Ensure the JSON is valid. \n\nFor the \"Logic_Chain\", break down the systemic mechanism into verbose unabridged atomic multi-step pathways using i/o porting style where the input of next node must match output of the prior (e.g., A -> B, B->C, C->D). Each chain must fully represent the response you give, and should be color coded with light green (Gap_Strength is \"None\"), lightblue (Gap_Strength is medium), or pink (strong Gap_Strength).

Do not alter a single character, do not paraphrase.\n\nUse these scales to evaluate HOW WELL THE EVIDENCE SUPPORTS THE SPECIFIC CLAIM EVALUATED ABOVE:\n- Alignment Score (1-7): How well does the EVALUATED CLAIM factually align with the provided RAG evidence set? [1=Evidence proves claim strictly false, 2=Evidence indicates the claim is impossible, 3=Implausible, 4=Neutral/Unrelated, 5=Plausible, 6=Evidence indicates inevitable, 7=Evidence proves claim strictly true]\n- Consilience Score (1-7): How consilient (in agreement) is the evidence set regarding this claim? [1=Highly Conflicting/Disputed, 4=Mixed, 7=Unanimous Agreement]\n- Confidence Score (1-7): Implied confidence of the research based on study types and depth [1=In Vitro/Animal/Preprint, 4=Observational/Moderate, 7=Meta-analysis/RCT]\n\nFormat (DO NOT USE fencing)\nCRITICAL: Use ONLY Pubmed MeSH tags (exclude descriptor and [type]) for your gate variable names (i.e.,.the \"gates\") so they will be standardized globally.

We evaluated the feasibility of a multimodal home monitoring protocol in ALS. Methods: We conducted a 3-month prospective cohort study at the University Medical Center Utrecht, Netherlands, with monthly home assessments of spirometry, accelerometry, speech, and questionnaires on functioning. The primary outcome was protocol adherence, defined as percentage of completed assessments. Secondary outcomes included acceptability ((totally) agree, neutral, (totally) disagree), and perceived burden, ranging from 0 (no burden) to 10 (extremely burdensome). Exploratory analyses were performed to evaluate changes in digital endpoints using linear mixed-effects models. Findings: Fifty patients with ALS were included (January 2023 - June 2025), of whom 47 (94%) completed the 3-month follow-up. Overall adherence was 83.2% (95% CI 76.9-88.6) and did not differ across modalities (p\u2009=\u20090.75). Adherers did not differ from non-adherers in either demographic or disease characteristics. In month 3, 93.0% to 95.3% of patients considered monthly remote assessments as acceptable, with a mean burden score of 2.0 (95% CI 1.7 to 2.3); burden was highest for speech (2.5) and the lowest for questionnaires (1.5). Digital endpoints showed significant change over 3\u2009months (all p\u2009<\u20090.05). Interpretation: This study demonstrates good adherence and acceptability of a multimodal remote monitoring protocol. Digital endpoints offer an innovative approach to capturing disease progression. Future research should assess its long-term feasibility, added value, and integration alongside established clinical outcomes."

The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech\u2011derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1\u2011weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS."

Effective management of progressive communication disorders requires a personalized approach to deliver timely interventions tailored to the evolving profiles of communicative impairment, thereby supporting functional communication throughout the disease course. To this end, reliable tools capable of detecting and quantifying both disease-specific patterns of communicative impairment and within-disease phenotypic variability are urgently needed. This study leverages Artificial Intelligence and advanced data analytics to develop an acoustic-based framework for automated extraction of interpretable, clinically grounded speech markers to enable objective assessment and phenotyping of progressive communication disorders. Three groups of participants, including 14 individuals with amyotrophic lateral sclerosis (ALS) and 15 individuals with Parkinson's disease (PD), alongside 10 neurologically healthy controls, performed a standardized oral passage reading task, yielding 739 speech samples. Fifty acoustic features were extracted using an automated analytic pipeline and subsequently clustered into six interpretable composite markers. The clinical utility of these markers was evaluated with the recorded speech samples by examining their (1) associations with standardized metrics of cognitive, motor speech, and overall communicative functions, (2) efficacy for detecting and differentiating disease-specific communicative impairment patterns in ALS and PD using supervised machine learning, and (3) utility for within-disease phenotyping and stratification using unsupervised clustering analysis. The markers effectively (1) detected subtle subclinical changes across multiple domains prior to substantial declines in functional communication outcomes; (2) differentiated disease-specific patterns of communicative impairment (multiclass area under the curve > 0.90); and (3) identified subgroups with distinct speech profiles within each disease. The findings support the potential of the proposed framework as a clinically translatable, objective tool to facilitate early detection, differential diagnosis, and phenotyping of progressive communication disorders, ultimately advancing personalized, measurement-based care in neurodegenerative diseases."

A clinically grounded sEMG framework was developed, integrating a standardized, repeatable protocol with a novel analytic pipeline, to automatically extract 60 features from six craniofacial muscle groups during a set of motorically demanding but cognitively and linguistically less challenging oral diadochokinetic (DDK) tasks. Using this framework, 104 oral DDK recordings were acquired from 16 individuals with ALS-nine with overt bulbar symptoms (ALS+B) and seven without (ALS-B)-and 10 healthy controls (HCs). The sEMG features were clustered into 10 interpretable composite measures and validated by evaluating their (1) internal consistency using Cronbach's \u03b1 ; (2) associations with standardized functional outcomes and a biomechanical metric-stiffness-via mediation analysis; (3) discriminatory efficacy in distinguishing ALS+B and ALS-B from HC, as well as from each other, using machine learning classifications; and (4) robustness to common nonmotor confounders, including age, sex, and cognitive-linguistic impairments, through a comparison of discriminatory performance before and after adjustment for these factors. All composite measures exhibited (1) high internal consistency (Cronbach's \u03b1 = 0.89 \u00b1 0.071 ), (2) significant (or marginally significant) direct or stiffness-mediated indirect associations with the functional outcomes, and (3) consistently high discriminatory accuracy (0.82-0.85), both before and after adjustment for confounders. The sEMG framework demonstrates strong potential as a reliable, valid, and robust objective tool to detect subclinical neuromuscular changes throughout the prodromal and symptomatic phases of bulbar involvement in ALS, while remaining resistant against disease-related cognitive-linguistic impairments and disease-unrelated confounders.

Remote monitoring is an evolving mode of health status tracking. This survey aimed to establish SLT perspectives on ALS assessment regarding 1) the clinical meaningfulness of existing outcome measurement instruments 2) remote monitoring 3) usefulness of assessment devices for patient care and 4) bulbar function outcomes and measurement instruments useful for research studies. An online English-language survey was distributed internationally through gatekeepers and social media. Sixty-six SLTs responded from 13 countries. Current outcome measurement instruments were regarded as clinically meaningful in ALS by 35% for speech and 41% for swallow. Only 12% had access to remote monitoring, but 77% would like to avail of it, with 58% perceiving its potential to enhance care. Eighty-two percent deemed remote monitoring using digital patient-reported outcome measures (PROMs) useful. Speech intelligibility measurement was selected as the most useful communication outcome for remote monitoring (92%) and research (94%). SLTs agreed that speech intelligibility test software (72%), smart device apps (70%) and tongue pressure measurement devices (54%) are useful assessment equipment. SLTs want better measurement instruments for speech and swallow in ALS. They regarded technologies including remote monitoring incorporating digital PROMs as useful. Outcomes reflecting communication and swallow functional success level were deemed most useful. These survey findings can inform the selection of digital speech and swallow outcomes for ALS."

We tracked signal characteristics and decoding over 25 months in a participant with ALS to determine how high-gamma (HG, 70-170 Hz) activity changes over time and whether these changes affect offline speech decoding. We implanted two 8\u00d78 subdural ECoG grids over left sensorimotor cortex (SMC) in a participant with slowly progressive bulbar variant ALS. Across 25 months, the participant performed an overt syllable-repetition task (12 consonant-vowel tokens) during simultaneous ECoG and audio recording. We quantified HG activation ratio (ActR), spectral signal-to-noise ratio (SNR; HG/HF, where HF = 300-499 Hz), and peak z-scored HG responses. Speech acoustics were evaluated using first/second formants (F1/F2) and the triangular vowel space area (tVSA). Offline EEGNet-based decoders were assessed in two stages: models trained on post-implant months 1-6 were tested on months 7-25, while models trained on stabilized data (months 7-11) were tested on the remaining period (months 12-25). Electrode-level saliency assessed spatial contributions to decoding. Acoustic analyses showed a significant reduction in tVSA over two years (-44.6 Hz2/day; P < 10-7), consistent with mild intelligibility decline. Neural metrics (ActR and SNR) followed a biphasic trajectory: increasing during the first 6 months, after which ActR stabilized (0.041%/day; P = 0.13), and SNR declined gradually (-0.46%/day, P < 10- 4). The model trained on months 1-6 achieved 55.7% accuracy (chance: 8.33%), but performance declined over time (-0.019%/day; P = 2.1\u00d710-4). Conversely, the model trained on months 7-11 achieved higher accuracy (65.9%) on subsequent data with no significant temporal decline (P = 0.23). Speech-related HG features exhibited an initial unstable period followed by a long-term gradual SNR reduction, potentially reflecting disease progression. Models trained after signal stabilization generalized robustly to data recorded over a year later. These findings confirm that despite reduced absolute HG power and mild acoustic degradation of speech, cortical features remain stable enough to support durable ECoG speech BCIs without frequent recalibration. These findings will motivate future adaptive calibration algorithms that account for slow signal changes while leveraging stable spatial representations in ventral SMC. NCT03567213."

Although acoustic voice analysis can detect phonatory alterations in ALS, its ability to differentiate clinical phenotypes remains limited. This study investigated whether biomechanical voice parameters provide complementary information for characterizing bulbar involvement across bulbar-onset ALS (ALS-B) and spinal-onset ALS (ALS-S) and explored their association with clinical and functional measures. Methods: This cross-sectional observational study included 50 patients with ALS (20 ALS-B, 30 ALS-S) and 50 controls with non-neurological voice disorders. Sustained vowel phonation was analyzed using acoustic measures and biomechanical voice parameters derived from a standardized model of vocal fold vibration. Perceptual voice severity was assessed using the GRBAS scale, while functional status was evaluated with the ALS Functional Rating Scale-Revised (ALSFRS-R) and the Barthel Index. Associations with clinical measures were explored in secondary analyses. Results: Compared with controls, ALS patients showed significant differences in acoustic measures and several biomechanical parameters related to glottal closure and vibratory stability. Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability. Unexpectedly, ALS-B showed greater perceptual voice severity and higher Barthel Index scores than ALS-S, while no differences were observed in global ALSFRS-R total scores. Conclusions: Biomechanical voice analysis appears to capture physiologically meaningful alterations in vocal fold function in ALS and provides complementary information for characterizing bulbar motor involvement across clinical phenotypes, particularly ALS-B disease. When combined with acoustic and clinical assessments, this approach may enhance the evaluation of bulbar involvement and functional status in ALS."

The \"ALS-OPM\" classification is based on the onset region (O), the propagation of motor symptoms (P), and the degree of clinical upper (UMN) and/or lower (LMN) motor neuron dysfunction (M). An international ALS expert focus group was held in September 2025, followed by a consensus process through which revisions of the OPM classification were finalized. Onset (O1-4) identifies first motor symptoms as relating to the head (O1), distal/proximal arm (O2d/p), respiratory/axial trunk (O3r/a), or distal/proximal leg (O4d/p). Onset symptoms are defined by weakness or slowed, poorly coordinated voluntary movements in the muscles of the head, arm, trunk, or leg, including dysarthria, dysphagia, dysphonia, dyspnea, and axial instability. Propagation (P1(n)) or absence of propagation (P0(n)) of motor symptoms from the onset region to another body region are designated, where n denotes the number of months from onset to propagation or assessment. The degree of UMN dysfunction (slowed, poorly coordinated voluntary movements, hyperreflexia and/or spastic muscle tone, emotional lability) and/or LMN dysfunction (weakness with associated muscle atrophy) is classified as follows: balanced UMN and LMN dysfunction (M0); dominant (M1d) or pure UMN dysfunction (M1p); dominant (M2d) or pure LMN dysfunction (M2p); and dissociated UMN/LMN dysfunction (M3), in which the arms and legs predominantly show LMN and UMN involvement, respectively. The revised ALS-OPM classification aims to make it routine, practical and feasible to capture phenotype in clinical practice and therapeutic trials."

A deep-learning U-Net++-based model was used for segmentation and feature extraction. The frequency and maximum amplitude of tongue movements were quantified. Clinical measures included the ALS Functional Rating Scale-revised (ALSFRS-r) bulbar sub-scores, tongue fasciculations, jaw jerk, and tongue \"spasticity\". Between-group differences and associations between tongue metrics and clinical features were assessed. The U-Net++-based model achieved robust segmentation performance. Patients showed lower tongue movement frequency than controls (0.14 vs. 0.40, t = -9.58, p < 0.001). Normalized frequency was associated with dysarthria (t = -3.13, p = 0.003) but not dysphagia (t = -1.05, p = 0.30).

Methods: A systematic review was conducted following a pre-registered protocol. Databases were searched for studies involving people living with ALS that addressed timing of assistive technology interventions for communication or technology control. Screening and data extraction were completed in duplicate, findings were synthesized using a thematic analysis, and relevant findings presented as a descriptive summary. Results: Twenty-eight studies met the inclusion criteria. Evidence focused overwhelmingly on communication support rather than wider assistive technology interventions. Need for a communication aid typically occurs between one and five years from diagnosis and the timing of this varies significantly according to the site of onset of ALS. There are significant variations in the timing of changes for individuals within these groupings and there are likely a larger number of groupings that would be clinically useful. A significant correlation between changes in speaking rate and intelligibility has been shown. Once changes to speech do start to occur then the time to the loss of functional speech appears relatively consistent across the types of ALS. Conclusion: Current best practice guidelines are not reflective of the findings of this review and do not support professionals in identifying how to provide timely support. Monitoring speech changes systematically may support timely intervention. There is potential for individual level predictive modeling to help support people living with ALS to be proactive and prepared for changes."

These disorders profoundly affect patient health and quality of life through complex sensorimotor impairments. Objective: The aims was to provide a comprehensive, evidence-based review of the neuroanatomical substrates, pathophysiology, diagnostic approaches, and management strategies for dysphagia and dysarthria in neurodegenerative diseases with emphasis on their multisystem nature and integrated treatment approaches. Methods: A narrative literature review was conducted using PubMed, Scopus, and Web of Science databases (2000-2024), focusing on Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), progressive supranuclear palsy (PSP), and multiple system atrophy (MSA). Search terms included \"dysphagia\", \"dysarthria\", \"neurodegenerative diseases\", \"neural networks\", \"swallowing control\" and \"speech production.\" Studies on neuroanatomy, pathophysiology, diagnostic tools, and therapeutic interventions were included. Results: Contemporary neuroscience demonstrates that swallowing and speech control involve extensive neural networks beyond the brainstem, including bilateral sensorimotor cortex, insula, cingulate gyrus, basal ganglia, and cerebellum. Disease-specific patterns reflect multisystem involvement: PD affects basal ganglia and multiple brainstem nuclei; ALS involves cortical and brainstem motor neurons; MSA causes widespread autonomic and motor degeneration; PSP produces tau-related damage across multiple brain regions. Diagnostic approaches combining fiberoptic endoscopic evaluation, videofluoroscopy, acoustic analysis, and neuroimaging enable precise characterization. Management requires multidisciplinary Integrated teams implementing coordinated speech-swallowing therapy, pharmacological interventions, and assistive technologies. Conclusions: Dysphagia and dysarthria in neurodegenerative diseases result from multifocal brain damage affecting distributed neural networks. Understanding this multisystem pathophysiology enables more effective integrated assessment and treatment approaches, enhancing patient outcomes and quality of life."

Early detection of bulbar symptoms is crucial for timely diagnosis and intervention; however, variability in symptom progression complicates clinical assessment. This retrospective observational study aimed to classify patients with ALS into three groups - spinal onset, spinal onset with bulbar involvement, and bulbar onset - and to identify speech evaluation metrics that effectively differentiate these groups. Data from 68 patients with ALS were retrospectively analyzed. Speech samples were collected and evaluated for alternating motion rate (AMR), maximum phonation time (MPT), nasality, maximum tongue pressure (MTP), speech rate, and speech intelligibility. Group comparisons and receiver operating characteristic (ROC) curve analyses were conducted to assess discriminatory ability. AMR significantly differed among the three groups, with the spinal-onset group demonstrating the highest rates and the bulbar-onset group showing the lowest rates. ROC analysis indicated that AMR exhibited excellent discriminatory power, particularly in distinguishing spinal-from bulbar-onset ALS. Significant differences were also observed in MTP, nasality, speech rate, and speech intelligibility, although some metrics were less effective in differentiating the intermediate group. No significant group differences were found in MPT. These findings suggest that the AMR is a sensitive and easily administered measure for detecting bulbar symptoms and distinguishing ALS subtypes. The intermediate characteristics observed in the spinal-onset with bulbar involvement group support this classification as a distinct clinical phenotype. Combining AMR with secondary measures such as MTP, nasality, speech rate, and speech intelligibility may enhance early detection of bulbar symptoms and improve clinical decision-making."

We conducted a retrospective study including 50 ALS patients evaluated in a phoniatrics consultation with available sustained vowel recordings, demographic data, and functional assessments. Nested logistic regression models were developed to predict clinical outcomes, progressively incorporating demographic variables, functional indices (Grade, Roughness, Breathiness, Asthenia, Strain, and Barthel), acoustic features (fundamental frequency, jitter, shimmer, harmonics-to-noise ratio), and biomechanical voice parameters (Pr1-Pr22). Model performance was assessed using receiver operating characteristic curves and area under the curve (AUC) comparisons via DeLong tests. Stepwise Akaike Information Criterion\u00a0(StepAIC) was applied to optimize the final model. A Cox proportional hazards model was used to evaluate the association between voice parameters and survival time.

Cox regression analysis showed that the derived risk scores stratified patients into tertiles with significantly different survival probabilities (log-rank P\u00a0<\u00a00.0001; hazard ratio for high vs. low-risk group\u00a0=\u00a011.2). Biomechanical voice features are strong predictors of mortality in ALS and outperform traditional clinical and acoustic indices. These findings support the integration of voice analysis into ALS monitoring protocols as a non-invasive, cost-effective, and scalable prognostic tool."

As interest in speech analysis grows, distinguishing between conditions becomes critical for reliable diagnosis and assessment. This pilot study explores speech biosignatures in two distinct neurodegenerative conditions: (1) mild traumatic brain injuries (eg, concussions) and (2) Parkinson disease (PD) as the neurodegenerative condition. The study included speech samples from 235 participants (97 concussed and 94 age-matched healthy controls, 29 PD and 15 healthy controls) for the PaTaKa test and 239 participants (91 concussed and 104 healthy controls, 29 PD and 15 healthy controls) for the Sustained Vowel (/ah/) test. Age-matched healthy controls were used. Young age-matched controls were used for concussion and respective age-matched controls for neurodegenerative participants (15 healthy samples for both tests). Data augmentation with noise was applied to balance small datasets for neurodegenerative and healthy controls. Machine learning models (support vector machine, decision tree, random forest, and Extreme Gradient Boosting) were employed using 37 temporal and spectral speech features. A 5-fold stratified cross-validation was used to evaluate classification performance. For the PaTaKa test, classifiers performed well, achieving F 1-scores above 0.9 for concussed versus healthy and concussed versus neurodegenerative classifications across all models. Initial tests using the original dataset for neurodegenerative versus healthy classification yielded very poor results, with F 1-scores below 0.2 and accuracy under 30% (eg, below 12 out of 44 correctly classified samples) across all models. This underscored the need for data augmentation, which significantly improved performance to 60%-70% (eg, 26-31 out of 44 samples) accuracy. In contrast, the Sustained Vowel test showed mixed results; F 1-scores remained high (more than 0.85 across all models) for concussed versus neurodegenerative classifications but were significantly lower for concussed versus healthy (0.59-0.62) and neurodegenerative versus healthy (0.33-0.77), depending on the model. This study highlights the potential of speech features as biomarkers for neurodegenerative conditions. The PaTaKa test exhibited strong discriminative ability, especially for concussed versus neurodegenerative and concussed versus healthy tasks, whereas challenges remain for neurodegenerative versus healthy classification. These findings emphasize the need for further exploration of speech-based tools for differential diagnosis and early identification in neurodegenerative health."

In neurodegenerative diseases affecting the brainstem-such as progressive supranuclear palsy (PSP), amyotrophic lateral sclerosis (ALS), and multiple system atrophy (MSA)-bulbar dysfunction often impairs tongue propulsion and motility, affecting both swallowing (dysphagia) and phonation (dysarthria). This study aimed to investigate whether vowel-based acoustic features are associated with swallowing severity in brainstem-related disorders and to explore their potential as surrogate markers of bulbar involvement. Methods: This was a cross-sectional observational study. Thirty-one patients (13 PSP, 12 ALS, 6 MSA) underwent clinical dysarthria assessment, acoustic analysis of the first (F1) and second (F2) formants during sustained phonation of /a/, /i/, /e/, and /u/, and swallowing evaluation using standardized clinical scales (DOSS, FOIS, ASHA-NOMS) and fiberoptic endoscopic evaluation (Pooling Score, Penetration-Aspiration Scale). The vowel space area (tVSA, qVSA) and Formant Centralization Ratio (FCR) were computed. Results: Significant correlations emerged between acoustic vowel metrics and dysphagia severity, especially for liquids. The FCR showed strong correlations with DOSS (\u03c1 = -0.660, p < 0.0001), FOIS (\u03c1 = -0.531, p = 0.002), ASHA-NOMS (\u03c1 = -0.604, p < 0.0001), and instrumental scores for liquids: the Pooling Score (\u03c1 = 0.538, p = 0.002) and PAS (\u03c1 = 0.630, p < 0.0001). VSA measures were also associated significantly with liquid swallowing impairment. F2u correlated with dysarthria severity and all liquid-related dysphagia scores. Conclusions: Vowel-based acoustic parameters, particularly FCR and F2u, reflect the shared neuromotor substrate of articulation and swallowing. Acoustic analysis may support early detection and monitoring of bulbar dysfunction, especially where instrumental assessments are limited."

Quantitative motor speech analysis can identify features of dysarthria that worsen with ALS progression but are not, inherently, clinically meaningful. Listener effort (LE) is a clinician-rated feature describing how much effort the listener needs to exert to understand the dysarthric speaker. This study investigated whether LE could act as a clinically meaningful measure of ALS dysarthria that could be used as an outcome measure in clinical trials. The Everything ALS Speech Study obtained longitudinal clinical information and speech recordings from 292 participants. In a subset of 125 participants, we measured speaking rate and three speech-language pathologists (SLPs) with expertise in ALS rated LE. We also built and tested a LE prediction algorithm to predict the SLPs' rating of LE. In addition, all speech recordings and associated clinical data are now being made available to ALS researchers via the Everything ALS portal. LE intra- and inter-rater reliability was very high (ICC 0.94-0.95). LE correlated with other measures of dysarthria at baseline and changed over time in participants with ALS (slope 0.77 pts/month, SE = 0.15, P < 0.001) but not controls (slope 0.005 pts/month, SE = 0.02, P = 0.807). The slope of LE progression was faster in people with bulbar onset than non-bulbar onset ALS (1.66 points/month versus 0.42 pts/month; P < 0.001) but was similar in all participants who had bulbar dysfunction at baseline, regardless of ALS site of onset (1.52 pts/month for bulbar onset versus 0.98 pts/month for non-bulbar onset with current bulbar involvement; P = 0.36). The LE prediction model predicted the true LE, with an average R 2 of 0.83 \u00b1 0.07. Dysarthria is associated with decreased quality of life in people with ALS. Quantitative measures of dysarthria in ALS could be useful as ALS clinical trial outcome measures, providing insight into the progression of bulbar symptoms. Speaking rate quantifies progression but is variable across speaking stimuli, emotional states and contextual factors. LE is more inherently clinically meaningful, can be measured reliably by SLPs, changes quantitatively over time and is highly reproducible, thus may be useful as a clinical outcome assessment for ALS clinical trials. Furthermore, a LE prediction model is effective at predicting LE scores and should be validated on an external dataset."

A validated objective marker is however lacking to characterize and phenotype bulbar involvement, positing a major barrier to early detection, progress monitoring, and tailored care. This study aimed to bridge this gap by constructing a multiplex functional mandibular muscle network to provide a novel objective measurement tool of bulbar involvement. A noninvasive electrophysiological technique-surface electromyography-was combined with graph network analysis to extract 48 features measuring the regulatory mechanisms, connectivity, integration, segregation, assortativity, and lateralization of the functional muscle network during a speech task. These features were clustered into 10 interpretable latent factors. To evaluate the utility of the muscle network as a bulbar measurement tool, a heterogenous ALS cohort, consisting of eight individuals with overt clinical bulbar symptoms and seven without, along with 10 neurologically healthy controls, was employed to train and validate statistical and machine learning algorithms to assess the disease effects on the network features and the relation of the network performance to the current clinical diagnostic standard and behavioral patterns of bulbar involvement. Significant disease effects were found on most network features. The most robust effects were manifested by reduced and more variable myoelectric activities, and reduced functional connectivity and integration of the muscle network. The 10 latent factors (1) demonstrated acceptably high efficacy for detecting bulbar neuromuscular changes across all clinically confirmed symptomatic cases and clinically silent prodromal cases (area under the curve = 0.89-0.91; F1 score = 0.85-0.87; precision = 0.84-0.86; recall = 0.87-0.88); and (2) selectively correlated with clinically meaningful behavioral patterns (conditional R 2 = 0.45-0.81). The functional muscle network shows promise for an objective quantifiable measurement tool to improve early detection and profiling of bulbar involvement across the prodromal and symptomatic stages. This tool has various strengths, including the use of a clinically readily available noninvasive instrument, fully automated data processing and analytics, and generation of interpretable objective outcome measures (i.e., latent factors), together rendering it highly scalable in routine clinical practice for assessing and monitoring of bulbar involvement."

Standard clinical tools for bulbar assessment focus primarily on clinical symptoms and functional outcomes. However, ALS is known to have a long, clinically silent prodromal stage characterized by complex subclinical changes at various levels of the bulbar motor system. These changes accumulate over time and eventually culminate in clinical symptoms and functional declines. Detection of these subclinical changes is critical, both for mechanistic understanding of bulbar neuromuscular pathology and for optimal clinical management of bulbar dysfunction in ALS. To this end, we developed a novel multimodal measurement tool based on two clinically readily available, noninvasive instruments-facial surface electromyography (sEMG) and acoustic techniques-to hierarchically assess seven constructs of bulbar/speech motor control at the neuromuscular and acoustic levels. These constructs, including prosody, pause, functional connectivity, amplitude, rhythm, complexity, and regularity, are both mechanically and clinically relevant to bulbar involvement. Using a custom-developed, fully automated data analytic algorithm, a variety of features were extracted from the sEMG and acoustic recordings of a speech task performed by 13 individuals with ALS and 10 neurologically healthy controls. These features were then factorized into 10 composite outcome measures using confirmatory factor analysis. Statistical and machine learning techniques were applied to these composite outcome measures to evaluate their reliability (internal consistency), validity (concurrent and construct), and efficacy for early detection and progress monitoring of bulbar involvement in ALS. The composite outcome measures were demonstrated to (1) be internally consistent and structurally valid in measuring the targeted constructs; (2) hold concurrent validity with the existing clinical and functional criteria for bulbar assessment; and (3) outperform the outcome measures obtained from each constituent modality in differentiating individuals with ALS from healthy controls. Moreover, the composite outcome measures combined demonstrated high efficacy for detecting subclinical changes in the targeted constructs, both during the prodromal stage and during the transition from prodromal to symptomatic stages. The findings provided compelling initial evidence for the utility of the multimodal measurement tool for improving early detection and progress monitoring of bulbar involvement in ALS, which have important implications in facilitating timely access to and delivery of optimal clinical care of bulbar dysfunction."

Automated acoustic assessment of speech in ALS is attractive, and there is a pressing need to validate such tools in line with best practices, including analytical and clinical validation. We hypothesized that data analysis using a novel speech assessment pipeline would correspond strongly to analyses performed using lab-standard practices and that acoustic features from the novel pipeline would correspond to clinical outcomes of interest in ALS. We analyzed data from three standard speech assessment tasks (i.e., vowel phonation, passage reading, and diadochokinesis) in 122 ALS patients. Data were analyzed automatically using a pipeline developed by Winterlight Labs, which yielded 53 acoustic features. First, for analytical validation, data were analyzed using a lab-standard analysis pipeline for comparison. This was followed by univariate analysis (Spearman correlations between individual features in Winterlight and in-lab datasets) and multivariate analysis (sparse canonical correlation analysis (SCCA)). Subsequently, clinical validation was performed. This included univariate analysis (Spearman correlation between automated acoustic features and clinical measures) and multivariate analysis (interpretable autoencoder-based dimensionality reduction). Analytical validity was demonstrated by substantial univariate correlations (Spearman's \u03c1\u2009>\u20090.70) between corresponding pairs of features from automated and lab-based datasets, as well as interpretable SCCA feature groups. Clinical validity was supported by strong univariate correlations between automated features and clinical measures (Spearman's \u03c1\u2009>\u20090.70), as well as associations between multivariate outputs and clinical measures. This novel, automated speech assessment feature set demonstrates substantial promise as a valid tool for analyzing impaired speech in ALS patients and for the further development of these technologies."

This study aimed to evaluate acoustic voice parameters as useful biomarkers to discriminate ALS clinical phenotypes. Triangular vowel space area (tVSA), alternating motion rates (AMRs), and sequential motion rates (SMRs) were analyzed in 36 ALS patients and 20 sex/age-matched healthy controls (HCs). tVSA, AMR, and SMR values significantly differed between ALS and HCs, and between ALS with prevalent upper (pUMN) and lower motor neuron (pLMN) impairment. tVSA showed higher accuracy in discriminating pUMN from pLMN patients. AMR and SMR were significantly lower in patients with bulbar onset than those with spinal onset, both with and without bulbar symptoms. Furthermore, these values were also lower in patients with spinal onset associated with bulbar symptoms than in those with spinal onset alone. Additionally, AMR and SMR values correlated with the degree of dysphagia.

Methods: Using their speech recordings, we measured articulatory precision (a measure of the crispness of pronunciation) using an algorithm that analyzed the acoustic signal of each phoneme in the words produced. First, we established the analytical and clinical validity of the measure of articulatory precision, showing that the measure correlated with perceptual ratings of articulatory precision (r = .9). Second, using articulatory precision from speech samples from each participant collected over a 45-90\u2009day model calibration period, we showed it was possible to predict articulatory precision 30-90 days after the last day of the model calibration period. Finally, we showed that the predicted articulatory precision scores mapped onto ALSFRS-R speech subscores.

It refers to motor neuron disability in the corticobulbar area of the brainstem which leads to a dysfunction of speech and swallowing. One of the earliest symptoms of bulbar dysfunction is voice deterioration characterized by grossly defective articulation, extremely slow laborious speech, marked hypernasality and severe harshness. Recently, research efforts have focused on voice analysis to capture this dysfunction. The main aim of this paper is to provide a new methodology to diagnose this dysfunction automatically at early stages of the disease, earlier than clinicians can do. The study focused on the creation of a voiceprint consisting of a pattern generated from the quasi-periodic components of a steady portion of the five Spanish vowels and the computation of the five principal and independent components of this pattern. Then, a set of statistically significant features was obtained using multivariate analysis of variance and the outcomes of the most common supervised classification models were obtained. The best model (random forest) obtained an accuracy, sensitivity and specificity of 88.3%, 85.0% and 95.0% respectively when classifying bulbar vs. control participants but the results worsened when classifying bulbar vs. no-bulbar patients (accuracy, sensitivity and specificity of 78.7%, 80.0% and 77.5% respectively for support vector machines). Due to the great uncertainty found in the annotated corpus of the ALS patients without bulbar involvement, we used a safe semi-supervised support vector machine to relabel the ALS participants diagnosed without bulbar involvement as bulbar and no-bulbar. The performance of the results obtained increased, especially when classifying bulbar and no-bulbar patients obtaining an accuracy, sensitivity and specificity of 91.0%, 83.3% and 100.0% respectively for support vector machines. This demonstrates that our model can improve the diagnosis of bulbar dysfunction compared not only with clinicians, but also the methods published to date. The results obtained demonstrate the efficiency and applicability of the methodology presented in this paper. It may lead to the development of a cheap and easy-to-use tool to identify this dysfunction in early stages of the disease and monitor progress."

Declining ALS-related speech scores correspond with worsening intelligibility in longitudinal assessments. Intelligibility correlates strongly with bulbar-specific clinical measures but not with global scores, highlighting its role in tracking bulbar progression. In some plwALS, we were able to demonstrate that automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring. Conclusion: Our findings highlight that automated speech intelligibility assessments can be a valuable marker to improve clinical monitoring and facilitate earlier intervention in ALS as a supplement to standard assessments."

The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech\u2011derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1\u2011weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS."

Effective management of progressive communication disorders requires a personalized approach to deliver timely interventions tailored to the evolving profiles of communicative impairment, thereby supporting functional communication throughout the disease course. To this end, reliable tools capable of detecting and quantifying both disease-specific patterns of communicative impairment and within-disease phenotypic variability are urgently needed. This study leverages Artificial Intelligence and advanced data analytics to develop an acoustic-based framework for automated extraction of interpretable, clinically grounded speech markers to enable objective assessment and phenotyping of progressive communication disorders. Three groups of participants, including 14 individuals with amyotrophic lateral sclerosis (ALS) and 15 individuals with Parkinson's disease (PD), alongside 10 neurologically healthy controls, performed a standardized oral passage reading task, yielding 739 speech samples. Fifty acoustic features were extracted using an automated analytic pipeline and subsequently clustered into six interpretable composite markers. The clinical utility of these markers was evaluated with the recorded speech samples by examining their (1) associations with standardized metrics of cognitive, motor speech, and overall communicative functions, (2) efficacy for detecting and differentiating disease-specific communicative impairment patterns in ALS and PD using supervised machine learning, and (3) utility for within-disease phenotyping and stratification using unsupervised clustering analysis. The markers effectively (1) detected subtle subclinical changes across multiple domains prior to substantial declines in functional communication outcomes; (2) differentiated disease-specific patterns of communicative impairment (multiclass area under the curve > 0.90); and (3) identified subgroups with distinct speech profiles within each disease. The findings support the potential of the proposed framework as a clinically translatable, objective tool to facilitate early detection, differential diagnosis, and phenotyping of progressive communication disorders, ultimately advancing personalized, measurement-based care in neurodegenerative diseases."

Dysarthria, characterized by impaired speech production, is common in ALS and often correlates with disease severity. Voice analysis has emerged as a promising tool for detecting disease progression and monitoring functional status. Methods: This study investigates acoustic and biomechanical voice alterations in ALS patients and their association with clinical measures of functional independence. A descriptive observational case series study was conducted, involving 43 ALS patients and 43 age and sex matched controls with non-neurological voice disorders. Sustained vowel /a/ recordings were obtained and analyzed using Voice Clinical Systems\u00ae and Praat software (version 6.2.22). Biomechanical and acoustic parameters were correlated with ALS Functional Rating Scale-Revised (ALSFRS-R) and Barthel Index scores. Results: Significant differences were observed between ALS and control groups (elevated muscle force and tension and interedge distance in non-ALS individuals). Between bulbar and spinal ALS subtypes, elevated values were observed in certain parameters in Bulbar ALS patients, indicating irregular vocal fold contact and weakened phonatory control, while spinal ALS exhibited increased values, suggesting higher phonatory muscle tension. Elevated biomechanical parameters were significantly correlated with low ALSFRS-R scores, suggesting a possible relationship between voice measures and functional decline. However, acoustic measurements showed no relationship with performance status. Conclusions: These results highlight the potential of voice analysis as a non-invasive, objective tool for monitoring ALS stage and differentiating between subtypes. Further research is needed to validate these findings and explore their clinical applications."

We assess past, current, and emerging trends in the prevalence and burden of mental disorders across sexes and age groups, for 21 regions, 204 countries and territories, and by Socio-demographic Index (SDI) quintile, from 1990 to 2023. Mental disorders included in GBD 2023 were anxiety disorders, major depressive disorder, dysthymia, bipolar disorder, schizophrenia, autism spectrum disorders, conduct disorder, attention-deficit hyperactivity disorder, anorexia nervosa, bulimia nervosa, idiopathic developmental intellectual disability, and a residual category of other mental disorders. A literature review identified epidemiological data for each disorder. These were analysed via a Bayesian meta-regression to estimate prevalence by disorder, sex, age, location, and year. Disorder-specific prevalence was multiplied by disability weights representing the severity of health loss associated with each disorder to estimate years lived with disability (YLDs). Deaths due to anorexia nervosa were assessed with a Cause of Death Ensemble modelling strategy to estimate deaths by sex, age, location, and year, and then multiplied by the standard life expectancy at age of death to estimate years of life lost (YLLs). YLDs equalled disability-adjusted life-years (DALYs) for all mental disorders except anorexia nervosa (the only mental disorder considered as an underlying cause of death in GBD), for which DALYs represented the sum of YLDs and YLLs. We presented prevalence, deaths, YLDs, YLLs, and DALYs as counts, age-specific rates per 100\u2008000 population, and age-standardised rates per 100\u2008000 population. We estimated 1\u00b717 billion (95% uncertainty interval 1\u00b706-1\u00b731) prevalent cases of mental disorders globally in 2023, equivalent to an age-standardised prevalence rate of 14\u2008210\u00b77 cases (12\u2008849\u00b75-15\u2008940\u00b71) per 100\u2008000 population. These estimates represented a 95\u00b75% (75\u00b70-121\u00b72) increase in prevalent cases and 24\u00b72% (11\u00b74-41\u00b74) increase in age-standardised prevalence rate between 1990 and 2023. All mental disorders showed increases in prevalent cases between 1990 and 2023, while notable increases were seen in age-standardised prevalence rates for anxiety disorders, major depressive disorder, dysthymia, anorexia nervosa, bulimia nervosa, schizophrenia, and conduct disorder. There were an estimated 171 million (127-228) DALYs due to mental disorders globally across sex and age in 2023, equivalent to an age-standardised DALY rate of 2070\u00b75 DALYs (1519\u00b71-2750\u00b75) per 100\u2008000 population. Mental disorders contributed to 6\u00b71% (4\u00b78-7\u00b76) of all-cause DALYs in 2023, making them the fifth leading cause of global DALYs (up from 12th in 1990). DALYs were almost entirely composed of YLDs. Mental disorders were the leading cause of YLDs in 2023 (up from second in 1990), explaining 17\u00b73% (14\u00b78-20\u00b76) of all-cause global YLDs. Leading causes of mental disorder DALYs were anxiety disorders (ranked 11th among the 304 diseases and injuries at Level 4 of the GBD cause hierarchy), major depressive disorder (15th), and schizophrenia (41st). Globally in 2023, mental disorder age-standardised DALY rates were higher among females (2239\u00b76 [1643\u00b77-3014\u00b71] per 100\u2008000) than among males (1900\u00b72 [1399\u00b78-2510\u00b78] per 100\u2008000), and peaked in the 15-19 years age group (2617\u00b73 [1850\u00b76-3696\u00b78] per 100\u2008000). All locations showed increased mental disorder DALY rates in 2023 compared with 1990, ranging across countries and territories from 1302\u00b74 (952\u00b77-1683\u00b77) per 100\u2008000 in Viet Nam to 3555\u00b78 (2661\u00b79-4715\u00b70) per 100\u2008000 in the Netherlands. Across SDI quintiles, DALY rates ranged from 1853\u00b70 (1352\u00b71-2469\u00b73) per 100\u2008000 for middle SDI to 2184\u00b71 (1606\u00b71-2890\u00b73) per 100\u2008000 for high SDI. A significant health burden was imposed by mental disorders in all countries and territories in 2023, irrespective of the health resources available. In some instances, this burden has increased over time and is unevenly distributed across populations. Stronger surveillance systems, particularly in low-income and middle-income countries, are required. Additionally, we need more coordinated and inclusive policies to reduce the burden through early treatment and prevention, tailored to sex and age differences across locations.

An anonymous online survey was distributed via MND organisations and groups to the Australian MND community. Two hundred and fourteen individuals completed the survey. Of those, 44.8% (n\u00a0=\u00a096) were HCPs, with the remaining consisting of people living with MND, genetic carriers, and carers. The following areas were rated as extremely important and should be included in the guideline: diagnosis, service delivery models, clinical care management, caregiver support, and palliative care; while views on genetic testing and cognitive assessment were mixed. Participants highlighted a need for holistic care which considered emotional/psychological and physical aspects of MND. People with MND and their carers want the Australian MND care guideline to highlight proactive and coordinated support prioritising quality of life, while maintaining independence for as long as possible. Identifying priorities is a fundamental step that will shape the forthcoming Australian MND care guideline. This methodology ensures the voices of those with lived experience and interest holders are incorporated from the outset.

In neurodegenerative diseases affecting the brainstem-such as progressive supranuclear palsy (PSP), amyotrophic lateral sclerosis (ALS), and multiple system atrophy (MSA)-bulbar dysfunction often impairs tongue propulsion and motility, affecting both swallowing (dysphagia) and phonation (dysarthria). This study aimed to investigate whether vowel-based acoustic features are associated with swallowing severity in brainstem-related disorders and to explore their potential as surrogate markers of bulbar involvement. Methods: This was a cross-sectional observational study. Thirty-one patients (13 PSP, 12 ALS, 6 MSA) underwent clinical dysarthria assessment, acoustic analysis of the first (F1) and second (F2) formants during sustained phonation of /a/, /i/, /e/, and /u/, and swallowing evaluation using standardized clinical scales (DOSS, FOIS, ASHA-NOMS) and fiberoptic endoscopic evaluation (Pooling Score, Penetration-Aspiration Scale). The vowel space area (tVSA, qVSA) and Formant Centralization Ratio (FCR) were computed. Results: Significant correlations emerged between acoustic vowel metrics and dysphagia severity, especially for liquids. The FCR showed strong correlations with DOSS (\u03c1 = -0.660, p < 0.0001), FOIS (\u03c1 = -0.531, p = 0.002), ASHA-NOMS (\u03c1 = -0.604, p < 0.0001), and instrumental scores for liquids: the Pooling Score (\u03c1 = 0.538, p = 0.002) and PAS (\u03c1 = 0.630, p < 0.0001). VSA measures were also associated significantly with liquid swallowing impairment. F2u correlated with dysarthria severity and all liquid-related dysphagia scores. Conclusions: Vowel-based acoustic parameters, particularly FCR and F2u, reflect the shared neuromotor substrate of articulation and swallowing. Acoustic analysis may support early detection and monitoring of bulbar dysfunction, especially where instrumental assessments are limited."

In 25% of ALS sufferers, speech disorders occur as prodromal symptoms of the disease. Impaired communication affects physical health and has a negative impact on mental and emotional condition. In this study, we assessed which domains of speech are particularly affected in ALS. Subsequently, we estimated possible correlations between the ALS patients' subjective perception of their speech quality and an objective assessment of the speech organs carried out by an expert. The study group consisted of 63 patients with sporadic ALS. The patients were examined for articulatory functions by means of Voice Handicap Index (VHI) and the Frenchay Dysarthria Assessment (FDA). On the basis of the VHI scores, the entire cohort was divided into 2 groups: group I (40 subjects) with mild speech impairment, and group II (23 subjects) displaying moderate and profound speech deficits. In an early phase of ALS, changes were typically reported in the tongue, lips and soft palate. The FDA and VHI-based measurements revealed a high, positive correlation between the objective and subjective evaluation of articulation quality. Deterioration of the articulatory organs resulted in the reduction of social, physical and emotional functioning. The highly positive correlation between the VHI and FDA scales seems to indicate that the VHI questionnaire may be a reliable, self-contained tool for monitoring the course and progression of speech disorders in ALS.

A cross-sectional sample of 100 individuals, including patients with ALS\u00a0and individuals with nonneurological dysphonia, was analyzed. Sustained vowel phonation was recorded and characterized using 26 variables, including standard acoustic measures (fundamental frequency -fo-, jitter, shimmer, and harmonics-to-noise ratio (HNR)) and 22 biomechanical parameters. Principal component analysis\u00a0was applied to investigate relationships among variables and reduce dimensionality. Unsupervised clustering was performed at both the variable level to identify functional groupings and the participant level to derive data-driven voice profiles. Cluster validity was assessed using internal indices. Post hoc statistical comparisons and chi-square tests were used descriptively to characterize between-cluster differences and their relationship with clinical categories. The first five principal components explained 70.7% of the total variance, revealing structured relationships between acoustic and biomechanical features. Participant level clustering consistently supported a two-profile solution. Fifteen voice parameters differed significantly between profiles after false discovery rate correction, with the largest effects observed for shimmer, HNR, and the biomechanical parameter Pr11, reflecting differences in vocal stability and noise-related characteristics. The identified profiles were not significantly associated with clinical diagnostic categories. An unsupervised multimodal analysis of sustained phonation revealed two coherent vocal profiles that transcend traditional diagnostic labels. These data-driven voice phenotypes may capture functional patterns of voice production and support future efforts toward more refined and personalized characterization of voice disorders."

In Cyprus, barriers such as long waiting lists, financial constraints, and limited public awareness restrict access to SLT services. University-led clinics offer a promising alternative by providing affordable, accessible care while training future clinicians. This study aimed to examine the demographic profiles, referral pathways, and diagnostic patterns of children accessing services at a university-led SLT clinic. By documenting referral trends and diagnostic outcomes, this study offers preliminary insights into patterns of service use and potential access disparities in the Cypriot context. Methods: A retrospective analysis was conducted using records from 235 children, aged 0;7 to 15 years, assessed at the University Rehabilitation Clinic between 2015 and 2024. Data included age, gender, socioeconomic status (SES), bilingualism, referral source, and diagnostic outcomes. Diagnoses were classified using Bishop et al.'s (2016) framework. Results: Significant associations were identified between age, parental education, referral source, and diagnostic category. Older children (9;1-12 years) demonstrated a markedly increased likelihood of receiving a developmental language disorder (DLD) diagnosis. Higher parental education levels and referrals from teachers or parents were also predictive of DLD and other communication impairments. Bilingualism was not a significant predictor of diagnostic category. Conclusions: The findings suggest that university-led clinics may serve as an important access point for underserved populations in Cyprus.

These disorders are clinically heterogeneous and therapeutically challenging, but advances in discovery science and trial methodology offer hope for translation to new treatments. Against this background, there is an urgent unmet need for biomarkers to aid with early and accurate diagnosis, prognosis and monitoring throughout the care pathway and in clinical trials.Investigations routinely used in clinical care and trials are often invasive, expensive, time-consuming, subjective and ordinal. Speech data represent a potentially scalable, non-invasive, objective and quantifiable digital biomarker that can be acquired remotely and cost-efficiently using mobile devices, and analysed using state-of-the-art speech signal processing and machine learning approaches. This prospective case-control observational study of multiple NDDs aims to deliver a deeply clinically phenotyped longitudinal speech dataset to facilitate development and evaluation of speech biomarkers. People living with dementia, motor neuron disease, multiple sclerosis and Parkinson's disease are eligible to participate. Healthy individuals (including relatives or carers of participants with neurological disease) are also eligible to participate as controls. Participants complete a study app with standardised speech recording tasks (including reading, free speech, picture description and verbal fluency tasks) and patient-reported outcome measures of quality of life and mood (EuroQol-5 Dimension-5 Level, Patient Health Questionnaire 2) every 2 months at home or in clinic. Participants also complete disease severity scales, cognitive screening tests and provide optional samples for blood-based biomarkers at baseline and then 6-monthly. Follow-up is scheduled for up to 24 months. Initially, 30 participants will be recruited to each group. Speech recordings and contemporaneous clinical data will be used to create a dataset for development and evaluation of novel speech-based diagnosis and monitoring algorithms.

We evaluated the feasibility of a multimodal home monitoring protocol in ALS. Methods: We conducted a 3-month prospective cohort study at the University Medical Center Utrecht, Netherlands, with monthly home assessments of spirometry, accelerometry, speech, and questionnaires on functioning. The primary outcome was protocol adherence, defined as percentage of completed assessments. Secondary outcomes included acceptability ((totally) agree, neutral, (totally) disagree), and perceived burden, ranging from 0 (no burden) to 10 (extremely burdensome). Exploratory analyses were performed to evaluate changes in digital endpoints using linear mixed-effects models. Findings: Fifty patients with ALS were included (January 2023 - June 2025), of whom 47 (94%) completed the 3-month follow-up. Overall adherence was 83.2% (95% CI 76.9-88.6) and did not differ across modalities (p\u2009=\u20090.75). Adherers did not differ from non-adherers in either demographic or disease characteristics. In month 3, 93.0% to 95.3% of patients considered monthly remote assessments as acceptable, with a mean burden score of 2.0 (95% CI 1.7 to 2.3); burden was highest for speech (2.5) and the lowest for questionnaires (1.5). Digital endpoints showed significant change over 3\u2009months (all p\u2009<\u20090.05). Interpretation: This study demonstrates good adherence and acceptability of a multimodal remote monitoring protocol. Digital endpoints offer an innovative approach to capturing disease progression. Future research should assess its long-term feasibility, added value, and integration alongside established clinical outcomes."

BCIs have been used to translate the neural correlates of attempted speech into text1-3. However, text communication fails to capture the nuances of human speech, such as prosody and immediately hearing one's own voice. Here we demonstrate a brain-to-voice neuroprosthesis that instantaneously synthesizes voice with closed-loop audio feedback by decoding neural activity from 256 microelectrodes implanted into the ventral precentral gyrus of a man with amyotrophic lateral sclerosis and severe dysarthria. We overcame the challenge of lacking ground-truth speech for training the neural decoder and were able to accurately synthesize his voice. Along with phonemic content, we were also able to decode paralinguistic features from intracortical activity, enabling the participant to modulate his BCI-synthesized voice in real time to change intonation and sing short melodies. These results demonstrate the feasibility of enabling people with paralysis to speak intelligibly and expressively through a BCI."

Methods: A retrospective analysis(case series study) was conducted on the laryngeal functional characteristics of 7 patients [2 males, 5 females, age ranged from 43 to 76(60.85\u00b113.18)]with motor neuron disease who visited the voice clinic and were ultimately diagnosed by neurologists. The data included laryngostroboscopy, fiberoptic endoscopic examination of swallowing(FEES), acoustic analysis and laryngeal electromyography(LEMG). Descriptive methods were used for analysis. Results: \u2460There were 2 males and 5 females, with an average age of (60.85\u00b113.18) years. They had previously visited the otolaryngology department more than twice, visit frequency with an average of 3.57 and an average diagnosis time of 12.28 months. The main complaints of the patient at the time of treatment were voice change, dysphagia or vocal fatigue. \u2461LEMG: Among 7 cases, 4 cases demonstrated neurogenic damage, all of which were bilateral, and 3 cases showed normal findings on examination. Spontaneous potentials (SP) were present in three cases for more than 6 months, with the longest duration being 24 months. Three cases exhibited the coexistence of spontaneous potential and reinnervated motor unit potentials (MUPs), and two cases showed bundle tremor potential.\u2462Laryngostroboscopy revealed bilateral vocal fold asymmetry and glottic insufficiency in 7 cases, and decreased vocal cord movement in 4 cases, and vocal cord atrophy in 5 cases. FEES showed that 7 patients presented with mild to severe swallowing dysfunction, 3 cases had soft palate insufficiency and mild to severe food residues in the epiglottic valley and pyriform fossa. 1 case showed leakage and 1 case showed aspiration. Conclusions: Patients presenting with initial symptoms of abnormal laryngeal function should be vigilant for the possibility of motor neuron disease, especially when laryngostroboscopy reveals abnormal vocal fold movement and swallowing dysfunction. LEMG examination reveals bilateral neurogenic damage, prolonged spontaneous potential, coexistence of spontaneous potential and reinnervated MUPs, and the appearance of bundle tremor potential, which is beneficial for early detection of motor neuron disease. \u76ee\u7684\uff1a \u5206\u6790\u9996\u8bca\u55d3\u97f3\u79d1\u7684\u808c\u840e\u7f29\u4fa7\u7d22\u786c\u5316\uff08amyotrophic lateral sclerosis\uff0cALS\uff09\u60a3\u8005\u7684\u5589\u90e8\u75c7\u72b6\u3001\u4f53\u5f81\u548c\u5589\u808c\u7535\u56fe\u7279\u70b9\u3002 \u65b9\u6cd5\uff1a \u8be5\u75c5\u4f8b\u7cfb\u5217\u7814\u7a76\u5206\u67902021\u5e744\u6708\u81f32023\u5e744\u6708\u5728\u53a6\u95e8\u5927\u5b66\u9644\u5c5e\u4e2d\u5c71\u533b\u9662\u55d3\u97f3\u95e8\u8bca\u9996\u8bca\u3001\u6700\u7ec8\u786e\u8bcaALS\u76847\u4f8b\u60a3\u8005\uff3b\u7537\u60272\u4f8b\uff0c\u5973\u60275\u4f8b\uff1b\u5e74\u9f84\u4e3a43~76\uff0860.85\u00b113.18\uff09\u5c81\uff3d\u7684\u5589\u90e8\u75c7\u72b6\u3001\u4f53\u5f81\uff08\u9891\u95ea\u5589\u955c\u3001\u541e\u54bd\u5589\u955c\uff09\u3001\u58f0\u5b66\u8bc4\u4f30\u53ca\u5589\u808c\u7535\u56fe\u8d44\u6599\u3002\u91c7\u7528\u63cf\u8ff0\u6027\u65b9\u6cd5\u8fdb\u884c\u5206\u6790\u3002 \u7ed3\u679c\uff1a \u24607\u4f8b\u60a3\u8005\u65e2\u5f80\u5747\u5728\u8033\u9f3b\u54bd\u5589\u79d1\u5c31\u8bca2\u6b21\u4ee5\u4e0a\uff08\u4e2d\u4f4d\u6b21\u65703.57\u6b21\uff09\uff0c\u786e\u8bca\u65f6\u95f4\u4e3a12.28\u4e2a\u6708\u3002\u5c31\u8bca\u65f6\u4e3b\u8bc9\u4e3b\u8981\u4e3a\uff1a\u58f0\u97f3\u5636\u54d1\u3001\u53d1\u58f0\u8d39\u529b\u3001\u53d1\u58f0\u75b2\u52b3\u3001\u541e\u54bd\u5f02\u7269\u611f\u6216\u541e\u54bd\u56f0\u96be\u3001\u547c\u5438\u4e0d\u7545\u53ca\u8bf4\u8bdd\u542b\u7cca\u7b49\u3002\u2461\u5589\u808c\u7535\u56fe\uff1a7\u4f8b\u4e2d4\u4f8b\u63d0\u793a\u4e3a\u795e\u7ecf\u6e90\u6027\u635f\u5bb3\uff0c\u4e14\u5747\u4e3a\u53cc\u4fa7\uff0c3\u4f8b\u68c0\u67e5\u6b63\u5e38\uff1b3\u4f8b\u53d1\u73b0\u81ea\u53d1\u7535\u4f4d\u8005\u5747\u51fa\u73b0\u57286\u4e2a\u6708\u4ee5\u4e0a\uff0c\u6700\u957f\u8005\u8fbe24\u4e2a\u6708\uff1b3\u4f8b\u53d1\u73b0\u8fdb\u884c\u6027\u5931\u795e\u7ecf\u635f\u5bb3\u548c\u6162\u6027\u518d\u751f\u5e76\u5b58\uff0c2\u4f8b\u51fa\u73b0\u675f\u98a4\u7535\u4f4d\u3002\u2462\u9891\u95ea\u5589\u955c\uff1a7\u4f8b\u60a3\u8005\u5747\u51fa\u73b0\u53cc\u4fa7\u58f0\u5e26\u8fd0\u52a8\u4e0d\u5bf9\u79f0\u548c\u58f0\u95e8\u95ed\u5408\u4e0d\u5168\uff084\u4f8b\u5782\u76f4\u9762\uff0c3\u4f8b\u6c34\u5e73\u9762\uff09\uff0c5\u4f8b\u58f0\u5e26\u677e\u5f1b\uff0c3\u4f8b\u53cc\u4fa7\u58f0\u5e26\u8fd0\u52a8\u51cf\u5f31\uff0c1\u4f8b\u5355\u4fa7\u58f0\u5e26\u8fd0\u52a8\u51cf\u5f31\u3002\u541e\u54bd\u5589\u955c\uff1a7\u4f8b\u60a3\u8005\u5747\u663e\u793a\u6709\u8f7b-\u91cd\u5ea6\u4e0d\u7b49\u7684\u541e\u54bd\u529f\u80fd\u969c\u788d\uff0c3\u4f8b\u60a3\u8005\u8f6f\u816d\u95ed\u5408\u4e0d\u5168\uff0c\u8fdb\u98df\u540e\u4f1a\u538c\u8c37\u53ca\u68a8\u72b6\u7a9d\u5747\u6709\u8f7b\u5ea6-\u91cd\u5ea6\u4e0d\u7b49\u7684\u98df\u7269\u6b8b\u7559\uff0c1\u4f8b\u89c1\u6e17\u6f0f\uff0c1\u4f8b\u89c1\u8bef\u5438\u3002 \u7ed3\u8bba\uff1a \u9996\u53d1\u75c7\u72b6\u4e3a\u5589\u529f\u80fd\u5f02\u5e38\u7684\u60a3\u8005\uff0c\u5f53\u9891\u95ea\u5589\u955c\u53d1\u73b0\u58f0\u5e26\u8fd0\u52a8\u529f\u80fd\u5f02\u5e38\u7279\u522b\u662f\u58f0\u95e8\u95ed\u5408\u4e0d\u5168\u540c\u65f6\u4f34\u6709\u541e\u54bd\u5589\u955c\u4e0b\u541e\u54bd\u529f\u80fd\u5f02\u5e38\u65f6\uff0c\u9700\u8b66\u60d5ALS\u7684\u53ef\u80fd\uff0c\u5589\u808c\u7535\u56fe\u68c0\u67e5\u53d1\u73b0\u53cc\u4fa7\u795e\u7ecf\u6e90\u6027\u635f\u5bb3\u3001\u81ea\u53d1\u7535\u4f4d\u957f\u65f6\u95f4\u6301\u7eed\u5b58\u5728\u3001\u81ea\u53d1\u7535\u4f4d\u548c\u5bbd\u5927\u8fd0\u52a8\u5355\u4f4d\u7535\u4f4d\uff08motor unit potential\uff0cMUP\uff09\u5e76\u5b58\u4ee5\u53ca\u675f\u98a4\u7535\u4f4d\u7684\u51fa\u73b0\uff0c\u6709\u52a9\u4e8e\u65e9\u671f\u53d1\u73b0\u8bca\u65adALS\u3002."

Although acoustic voice analysis can detect phonatory alterations in ALS, its ability to differentiate clinical phenotypes remains limited. This study investigated whether biomechanical voice parameters provide complementary information for characterizing bulbar involvement across bulbar-onset ALS (ALS-B) and spinal-onset ALS (ALS-S) and explored their association with clinical and functional measures. Methods: This cross-sectional observational study included 50 patients with ALS (20 ALS-B, 30 ALS-S) and 50 controls with non-neurological voice disorders. Sustained vowel phonation was analyzed using acoustic measures and biomechanical voice parameters derived from a standardized model of vocal fold vibration. Perceptual voice severity was assessed using the GRBAS scale, while functional status was evaluated with the ALS Functional Rating Scale-Revised (ALSFRS-R) and the Barthel Index. Associations with clinical measures were explored in secondary analyses. Results: Compared with controls, ALS patients showed significant differences in acoustic measures and several biomechanical parameters related to glottal closure and vibratory stability. Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability. Unexpectedly, ALS-B showed greater perceptual voice severity and higher Barthel Index scores than ALS-S, while no differences were observed in global ALSFRS-R total scores. Conclusions: Biomechanical voice analysis appears to capture physiologically meaningful alterations in vocal fold function in ALS and provides complementary information for characterizing bulbar motor involvement across clinical phenotypes, particularly ALS-B disease. When combined with acoustic and clinical assessments, this approach may enhance the evaluation of bulbar involvement and functional status in ALS."

We aim to describe the most frequent otolaryngology (ORL) complaints and voice disturbances in patients with bulbar onset ALS. Retrospective cohort study. Single-center study with combined ORL and ALS clinic evaluation. Patients with a confirmed diagnosis of ALS following an ORL visit and who underwent comprehensive voice assessments between January 2021 and January 2023. Objective voice assessments. Glottal functional index (GFI), voice handicap index (VHI), reflux system index (RSI), and voice quality characteristics such as shimmer, jitter, maximum phonation time (MPT), and other essential parameters were assessed. One hundred and thirty-three patients (age 62.17\u00a0\u00b1\u00a010.79, 54.48% female) were included. Three patients were referred from the ORL department to the ALS clinic.

As interest in speech analysis grows, distinguishing between conditions becomes critical for reliable diagnosis and assessment. This pilot study explores speech biosignatures in two distinct neurodegenerative conditions: (1) mild traumatic brain injuries (eg, concussions) and (2) Parkinson disease (PD) as the neurodegenerative condition. The study included speech samples from 235 participants (97 concussed and 94 age-matched healthy controls, 29 PD and 15 healthy controls) for the PaTaKa test and 239 participants (91 concussed and 104 healthy controls, 29 PD and 15 healthy controls) for the Sustained Vowel (/ah/) test. Age-matched healthy controls were used. Young age-matched controls were used for concussion and respective age-matched controls for neurodegenerative participants (15 healthy samples for both tests). Data augmentation with noise was applied to balance small datasets for neurodegenerative and healthy controls. Machine learning models (support vector machine, decision tree, random forest, and Extreme Gradient Boosting) were employed using 37 temporal and spectral speech features. A 5-fold stratified cross-validation was used to evaluate classification performance. For the PaTaKa test, classifiers performed well, achieving F 1-scores above 0.9 for concussed versus healthy and concussed versus neurodegenerative classifications across all models. Initial tests using the original dataset for neurodegenerative versus healthy classification yielded very poor results, with F 1-scores below 0.2 and accuracy under 30% (eg, below 12 out of 44 correctly classified samples) across all models. This underscored the need for data augmentation, which significantly improved performance to 60%-70% (eg, 26-31 out of 44 samples) accuracy. In contrast, the Sustained Vowel test showed mixed results; F 1-scores remained high (more than 0.85 across all models) for concussed versus neurodegenerative classifications but were significantly lower for concussed versus healthy (0.59-0.62) and neurodegenerative versus healthy (0.33-0.77), depending on the model. This study highlights the potential of speech features as biomarkers for neurodegenerative conditions. The PaTaKa test exhibited strong discriminative ability, especially for concussed versus neurodegenerative and concussed versus healthy tasks, whereas challenges remain for neurodegenerative versus healthy classification. These findings emphasize the need for further exploration of speech-based tools for differential diagnosis and early identification in neurodegenerative health."

In 25% of ALS sufferers, speech disorders occur as prodromal symptoms of the disease. Impaired communication affects physical health and has a negative impact on mental and emotional condition. In this study, we assessed which domains of speech are particularly affected in ALS. Subsequently, we estimated possible correlations between the ALS patients' subjective perception of their speech quality and an objective assessment of the speech organs carried out by an expert. The study group consisted of 63 patients with sporadic ALS. The patients were examined for articulatory functions by means of Voice Handicap Index (VHI) and the Frenchay Dysarthria Assessment (FDA). On the basis of the VHI scores, the entire cohort was divided into 2 groups: group I (40 subjects) with mild speech impairment, and group II (23 subjects) displaying moderate and profound speech deficits. In an early phase of ALS, changes were typically reported in the tongue, lips and soft palate. The FDA and VHI-based measurements revealed a high, positive correlation between the objective and subjective evaluation of articulation quality. Deterioration of the articulatory organs resulted in the reduction of social, physical and emotional functioning. The highly positive correlation between the VHI and FDA scales seems to indicate that the VHI questionnaire may be a reliable, self-contained tool for monitoring the course and progression of speech disorders in ALS.

This review provides a comprehensive overview of the current knowledge on the clinical manifestations, diagnostic differentiation, underlying mechanisms, diagnostic tools, and therapeutic strategies for the treatment of dysarthria in ALS. We update on the most promising digital speech biomarkers of ALS that are critical for early and differential diagnosis. Advances in artificial intelligence and digital speech processing have transformed the analysis of speech patterns, and offer the opportunity to start therapy early to improve vocal function, as speech rate appears to decline significantly before the diagnosis of ALS is confirmed. In addition, we discuss the impact of interventions that can improve vocal function and quality of life for patients, such as compensatory speech techniques, surgical options, improving lung function and respiratory muscle strength, and percutaneous dilated tracheostomy, possibly with adjunctive therapies to treat respiratory insufficiency, and finally assistive devices for alternative communication."

The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech\u2011derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1\u2011weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS."

Speech intelligibility is a crucial component of communication affected in ALS, requiring objective, scalable assessment methods as an indicator of disease progression and treatment efficacy. Objective: This study investigates whether speech and bulbar function in ALS could be evaluated and monitored utilizing an automated digital measure of speech intelligibility derived from naturalistic picture descriptions. Methods: Speech recordings from 44 patients living with ALS (plwALS) and 49 matched healthy controls (HC) were analyzed and processed utilizing an automated speech analysis pipeline to extract an intelligibility score. These were part of a cross-sectional and longitudinal study involving two assessments.\u00a0Results: The findings confirmed that speech intelligibility is significantly reduced in plwALS compared to HC. Those with bulbar-onset ALS have lower intelligibility than those with spinal-onset ALS, and the intelligibility of individuals with bulbar symptoms-regardless of the onset type-is lower than in plwALS without bulbar symptoms. Declining ALS-related speech scores correspond with worsening intelligibility in longitudinal assessments. Intelligibility correlates strongly with bulbar-specific clinical measures but not with global scores, highlighting its role in tracking bulbar progression. In some plwALS, we were able to demonstrate that automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring. Conclusion: Our findings highlight that automated speech intelligibility assessments can be a valuable marker to improve clinical monitoring and facilitate earlier intervention in ALS as a supplement to standard assessments."

Effective management of progressive communication disorders requires a personalized approach to deliver timely interventions tailored to the evolving profiles of communicative impairment, thereby supporting functional communication throughout the disease course. To this end, reliable tools capable of detecting and quantifying both disease-specific patterns of communicative impairment and within-disease phenotypic variability are urgently needed. This study leverages Artificial Intelligence and advanced data analytics to develop an acoustic-based framework for automated extraction of interpretable, clinically grounded speech markers to enable objective assessment and phenotyping of progressive communication disorders. Three groups of participants, including 14 individuals with amyotrophic lateral sclerosis (ALS) and 15 individuals with Parkinson's disease (PD), alongside 10 neurologically healthy controls, performed a standardized oral passage reading task, yielding 739 speech samples. Fifty acoustic features were extracted using an automated analytic pipeline and subsequently clustered into six interpretable composite markers. The clinical utility of these markers was evaluated with the recorded speech samples by examining their (1) associations with standardized metrics of cognitive, motor speech, and overall communicative functions, (2) efficacy for detecting and differentiating disease-specific communicative impairment patterns in ALS and PD using supervised machine learning, and (3) utility for within-disease phenotyping and stratification using unsupervised clustering analysis. The markers effectively (1) detected subtle subclinical changes across multiple domains prior to substantial declines in functional communication outcomes; (2) differentiated disease-specific patterns of communicative impairment (multiclass area under the curve > 0.90); and (3) identified subgroups with distinct speech profiles within each disease. The findings support the potential of the proposed framework as a clinically translatable, objective tool to facilitate early detection, differential diagnosis, and phenotyping of progressive communication disorders, ultimately advancing personalized, measurement-based care in neurodegenerative diseases."

Dysarthria, characterized by impaired speech production, is common in ALS and often correlates with disease severity. Voice analysis has emerged as a promising tool for detecting disease progression and monitoring functional status. Methods: This study investigates acoustic and biomechanical voice alterations in ALS patients and their association with clinical measures of functional independence. A descriptive observational case series study was conducted, involving 43 ALS patients and 43 age and sex matched controls with non-neurological voice disorders. Sustained vowel /a/ recordings were obtained and analyzed using Voice Clinical Systems\u00ae and Praat software (version 6.2.22). Biomechanical and acoustic parameters were correlated with ALS Functional Rating Scale-Revised (ALSFRS-R) and Barthel Index scores. Results: Significant differences were observed between ALS and control groups (elevated muscle force and tension and interedge distance in non-ALS individuals). Between bulbar and spinal ALS subtypes, elevated values were observed in certain parameters in Bulbar ALS patients, indicating irregular vocal fold contact and weakened phonatory control, while spinal ALS exhibited increased values, suggesting higher phonatory muscle tension. Elevated biomechanical parameters were significantly correlated with low ALSFRS-R scores, suggesting a possible relationship between voice measures and functional decline. However, acoustic measurements showed no relationship with performance status. Conclusions: These results highlight the potential of voice analysis as a non-invasive, objective tool for monitoring ALS stage and differentiating between subtypes. Further research is needed to validate these findings and explore their clinical applications."

We assess past, current, and emerging trends in the prevalence and burden of mental disorders across sexes and age groups, for 21 regions, 204 countries and territories, and by Socio-demographic Index (SDI) quintile, from 1990 to 2023. Mental disorders included in GBD 2023 were anxiety disorders, major depressive disorder, dysthymia, bipolar disorder, schizophrenia, autism spectrum disorders, conduct disorder, attention-deficit hyperactivity disorder, anorexia nervosa, bulimia nervosa, idiopathic developmental intellectual disability, and a residual category of other mental disorders. A literature review identified epidemiological data for each disorder. These were analysed via a Bayesian meta-regression to estimate prevalence by disorder, sex, age, location, and year. Disorder-specific prevalence was multiplied by disability weights representing the severity of health loss associated with each disorder to estimate years lived with disability (YLDs). Deaths due to anorexia nervosa were assessed with a Cause of Death Ensemble modelling strategy to estimate deaths by sex, age, location, and year, and then multiplied by the standard life expectancy at age of death to estimate years of life lost (YLLs). YLDs equalled disability-adjusted life-years (DALYs) for all mental disorders except anorexia nervosa (the only mental disorder considered as an underlying cause of death in GBD), for which DALYs represented the sum of YLDs and YLLs. We presented prevalence, deaths, YLDs, YLLs, and DALYs as counts, age-specific rates per 100\u2008000 population, and age-standardised rates per 100\u2008000 population. We estimated 1\u00b717 billion (95% uncertainty interval 1\u00b706-1\u00b731) prevalent cases of mental disorders globally in 2023, equivalent to an age-standardised prevalence rate of 14\u2008210\u00b77 cases (12\u2008849\u00b75-15\u2008940\u00b71) per 100\u2008000 population. These estimates represented a 95\u00b75% (75\u00b70-121\u00b72) increase in prevalent cases and 24\u00b72% (11\u00b74-41\u00b74) increase in age-standardised prevalence rate between 1990 and 2023. All mental disorders showed increases in prevalent cases between 1990 and 2023, while notable increases were seen in age-standardised prevalence rates for anxiety disorders, major depressive disorder, dysthymia, anorexia nervosa, bulimia nervosa, schizophrenia, and conduct disorder. There were an estimated 171 million (127-228) DALYs due to mental disorders globally across sex and age in 2023, equivalent to an age-standardised DALY rate of 2070\u00b75 DALYs (1519\u00b71-2750\u00b75) per 100\u2008000 population. Mental disorders contributed to 6\u00b71% (4\u00b78-7\u00b76) of all-cause DALYs in 2023, making them the fifth leading cause of global DALYs (up from 12th in 1990). DALYs were almost entirely composed of YLDs. Mental disorders were the leading cause of YLDs in 2023 (up from second in 1990), explaining 17\u00b73% (14\u00b78-20\u00b76) of all-cause global YLDs. Leading causes of mental disorder DALYs were anxiety disorders (ranked 11th among the 304 diseases and injuries at Level 4 of the GBD cause hierarchy), major depressive disorder (15th), and schizophrenia (41st). Globally in 2023, mental disorder age-standardised DALY rates were higher among females (2239\u00b76 [1643\u00b77-3014\u00b71] per 100\u2008000) than among males (1900\u00b72 [1399\u00b78-2510\u00b78] per 100\u2008000), and peaked in the 15-19 years age group (2617\u00b73 [1850\u00b76-3696\u00b78] per 100\u2008000). All locations showed increased mental disorder DALY rates in 2023 compared with 1990, ranging across countries and territories from 1302\u00b74 (952\u00b77-1683\u00b77) per 100\u2008000 in Viet Nam to 3555\u00b78 (2661\u00b79-4715\u00b70) per 100\u2008000 in the Netherlands. Across SDI quintiles, DALY rates ranged from 1853\u00b70 (1352\u00b71-2469\u00b73) per 100\u2008000 for middle SDI to 2184\u00b71 (1606\u00b71-2890\u00b73) per 100\u2008000 for high SDI. A significant health burden was imposed by mental disorders in all countries and territories in 2023, irrespective of the health resources available. In some instances, this burden has increased over time and is unevenly distributed across populations. Stronger surveillance systems, particularly in low-income and middle-income countries, are required. Additionally, we need more coordinated and inclusive policies to reduce the burden through early treatment and prevention, tailored to sex and age differences across locations. Responding to the mental health needs of our global population, especially those most vulnerable, is an obligation, not a choice. Gates Foundation, Queensland Health, and University of Queensland."

An anonymous online survey was distributed via MND organisations and groups to the Australian MND community. Two hundred and fourteen individuals completed the survey. Of those, 44.8% (n\u00a0=\u00a096) were HCPs, with the remaining consisting of people living with MND, genetic carriers, and carers. The following areas were rated as extremely important and should be included in the guideline: diagnosis, service delivery models, clinical care management, caregiver support, and palliative care; while views on genetic testing and cognitive assessment were mixed. Participants highlighted a need for holistic care which considered emotional/psychological and physical aspects of MND. People with MND and their carers want the Australian MND care guideline to highlight proactive and coordinated support prioritising quality of life, while maintaining independence for as long as possible. Identifying priorities is a fundamental step that will shape the forthcoming Australian MND care guideline. This methodology ensures the voices of those with lived experience and interest holders are incorporated from the outset.

In neurodegenerative diseases affecting the brainstem-such as progressive supranuclear palsy (PSP), amyotrophic lateral sclerosis (ALS), and multiple system atrophy (MSA)-bulbar dysfunction often impairs tongue propulsion and motility, affecting both swallowing (dysphagia) and phonation (dysarthria). This study aimed to investigate whether vowel-based acoustic features are associated with swallowing severity in brainstem-related disorders and to explore their potential as surrogate markers of bulbar involvement. Methods: This was a cross-sectional observational study. Thirty-one patients (13 PSP, 12 ALS, 6 MSA) underwent clinical dysarthria assessment, acoustic analysis of the first (F1) and second (F2) formants during sustained phonation of /a/, /i/, /e/, and /u/, and swallowing evaluation using standardized clinical scales (DOSS, FOIS, ASHA-NOMS) and fiberoptic endoscopic evaluation (Pooling Score, Penetration-Aspiration Scale). The vowel space area (tVSA, qVSA) and Formant Centralization Ratio (FCR) were computed. Results: Significant correlations emerged between acoustic vowel metrics and dysphagia severity, especially for liquids. The FCR showed strong correlations with DOSS (\u03c1 = -0.660, p < 0.0001), FOIS (\u03c1 = -0.531, p = 0.002), ASHA-NOMS (\u03c1 = -0.604, p < 0.0001), and instrumental scores for liquids: the Pooling Score (\u03c1 = 0.538, p = 0.002) and PAS (\u03c1 = 0.630, p < 0.0001). VSA measures were also associated significantly with liquid swallowing impairment. F2u correlated with dysarthria severity and all liquid-related dysphagia scores. Conclusions: Vowel-based acoustic parameters, particularly FCR and F2u, reflect the shared neuromotor substrate of articulation and swallowing. Acoustic analysis may support early detection and monitoring of bulbar dysfunction, especially where instrumental assessments are limited."

A cross-sectional sample of 100 individuals, including patients with ALS\u00a0and individuals with nonneurological dysphonia, was analyzed. Sustained vowel phonation was recorded and characterized using 26 variables, including standard acoustic measures (fundamental frequency -fo-, jitter, shimmer, and harmonics-to-noise ratio (HNR)) and 22 biomechanical parameters. Principal component analysis\u00a0was applied to investigate relationships among variables and reduce dimensionality. Unsupervised clustering was performed at both the variable level to identify functional groupings and the participant level to derive data-driven voice profiles. Cluster validity was assessed using internal indices. Post hoc statistical comparisons and chi-square tests were used descriptively to characterize between-cluster differences and their relationship with clinical categories. The first five principal components explained 70.7% of the total variance, revealing structured relationships between acoustic and biomechanical features. Participant level clustering consistently supported a two-profile solution. Fifteen voice parameters differed significantly between profiles after false discovery rate correction, with the largest effects observed for shimmer, HNR, and the biomechanical parameter Pr11, reflecting differences in vocal stability and noise-related characteristics. The identified profiles were not significantly associated with clinical diagnostic categories. An unsupervised multimodal analysis of sustained phonation revealed two coherent vocal profiles that transcend traditional diagnostic labels.

In Cyprus, barriers such as long waiting lists, financial constraints, and limited public awareness restrict access to SLT services. University-led clinics offer a promising alternative by providing affordable, accessible care while training future clinicians. This study aimed to examine the demographic profiles, referral pathways, and diagnostic patterns of children accessing services at a university-led SLT clinic. By documenting referral trends and diagnostic outcomes, this study offers preliminary insights into patterns of service use and potential access disparities in the Cypriot context.

Results: Significant associations were identified between age, parental education, referral source, and diagnostic category. Older children (9;1-12 years) demonstrated a markedly increased likelihood of receiving a developmental language disorder (DLD) diagnosis. Higher parental education levels and referrals from teachers or parents were also predictive of DLD and other communication impairments. Bilingualism was not a significant predictor of diagnostic category.

These disorders are clinically heterogeneous and therapeutically challenging, but advances in discovery science and trial methodology offer hope for translation to new treatments. Against this background, there is an urgent unmet need for biomarkers to aid with early and accurate diagnosis, prognosis and monitoring throughout the care pathway and in clinical trials.Investigations routinely used in clinical care and trials are often invasive, expensive, time-consuming, subjective and ordinal. Speech data represent a potentially scalable, non-invasive, objective and quantifiable digital biomarker that can be acquired remotely and cost-efficiently using mobile devices, and analysed using state-of-the-art speech signal processing and machine learning approaches. This prospective case-control observational study of multiple NDDs aims to deliver a deeply clinically phenotyped longitudinal speech dataset to facilitate development and evaluation of speech biomarkers. People living with dementia, motor neuron disease, multiple sclerosis and Parkinson's disease are eligible to participate. Healthy individuals (including relatives or carers of participants with neurological disease) are also eligible to participate as controls. Participants complete a study app with standardised speech recording tasks (including reading, free speech, picture description and verbal fluency tasks) and patient-reported outcome measures of quality of life and mood (EuroQol-5 Dimension-5 Level, Patient Health Questionnaire 2) every 2 months at home or in clinic. Participants also complete disease severity scales, cognitive screening tests and provide optional samples for blood-based biomarkers at baseline and then 6-monthly. Follow-up is scheduled for up to 24 months. Initially, 30 participants will be recruited to each group. Speech recordings and contemporaneous clinical data will be used to create a dataset for development and evaluation of novel speech-based diagnosis and monitoring algorithms.

Findings: Fifty patients with ALS were included (January 2023 - June 2025), of whom 47 (94%) completed the 3-month follow-up. Overall adherence was 83.2% (95% CI 76.9-88.6) and did not differ across modalities (p\u2009=\u20090.75). Adherers did not differ from non-adherers in either demographic or disease characteristics. In month 3, 93.0% to 95.3% of patients considered monthly remote assessments as acceptable, with a mean burden score of 2.0 (95% CI 1.7 to 2.3); burden was highest for speech (2.5) and the lowest for questionnaires (1.5). Digital endpoints showed significant change over 3\u2009months (all p\u2009<\u20090.05). Interpretation: This study demonstrates good adherence and acceptability of a multimodal remote monitoring protocol. Digital endpoints offer an innovative approach to capturing disease progression. Future research should assess its long-term feasibility, added value, and integration alongside established clinical outcomes."

BCIs have been used to translate the neural correlates of attempted speech into text1-3. However, text communication fails to capture the nuances of human speech, such as prosody and immediately hearing one's own voice. Here we demonstrate a brain-to-voice neuroprosthesis that instantaneously synthesizes voice with closed-loop audio feedback by decoding neural activity from 256 microelectrodes implanted into the ventral precentral gyrus of a man with amyotrophic lateral sclerosis and severe dysarthria. We overcame the challenge of lacking ground-truth speech for training the neural decoder and were able to accurately synthesize his voice. Along with phonemic content, we were also able to decode paralinguistic features from intracortical activity, enabling the participant to modulate his BCI-synthesized voice in real time to change intonation and sing short melodies. These results demonstrate the feasibility of enabling people with paralysis to speak intelligibly and expressively through a BCI."

Methods: A retrospective analysis(case series study) was conducted on the laryngeal functional characteristics of 7 patients [2 males, 5 females, age ranged from 43 to 76(60.85\u00b113.18)]with motor neuron disease who visited the voice clinic and were ultimately diagnosed by neurologists. The data included laryngostroboscopy, fiberoptic endoscopic examination of swallowing(FEES), acoustic analysis and laryngeal electromyography(LEMG). Descriptive methods were used for analysis. Results: \u2460There were 2 males and 5 females, with an average age of (60.85\u00b113.18) years. They had previously visited the otolaryngology department more than twice, visit frequency with an average of 3.57 and an average diagnosis time of 12.28 months. The main complaints of the patient at the time of treatment were voice change, dysphagia or vocal fatigue. \u2461LEMG: Among 7 cases, 4 cases demonstrated neurogenic damage, all of which were bilateral, and 3 cases showed normal findings on examination. Spontaneous potentials (SP) were present in three cases for more than 6 months, with the longest duration being 24 months. Three cases exhibited the coexistence of spontaneous potential and reinnervated motor unit potentials (MUPs), and two cases showed bundle tremor potential.\u2462Laryngostroboscopy revealed bilateral vocal fold asymmetry and glottic insufficiency in 7 cases, and decreased vocal cord movement in 4 cases, and vocal cord atrophy in 5 cases. FEES showed that 7 patients presented with mild to severe swallowing dysfunction, 3 cases had soft palate insufficiency and mild to severe food residues in the epiglottic valley and pyriform fossa. 1 case showed leakage and 1 case showed aspiration. Conclusions: Patients presenting with initial symptoms of abnormal laryngeal function should be vigilant for the possibility of motor neuron disease, especially when laryngostroboscopy reveals abnormal vocal fold movement and swallowing dysfunction. LEMG examination reveals bilateral neurogenic damage, prolonged spontaneous potential, coexistence of spontaneous potential and reinnervated MUPs, and the appearance of bundle tremor potential, which is beneficial for early detection of motor neuron disease. \u76ee\u7684\uff1a \u5206\u6790\u9996\u8bca\u55d3\u97f3\u79d1\u7684\u808c\u840e\u7f29\u4fa7\u7d22\u786c\u5316\uff08amyotrophic lateral sclerosis\uff0cALS\uff09\u60a3\u8005\u7684\u5589\u90e8\u75c7\u72b6\u3001\u4f53\u5f81\u548c\u5589\u808c\u7535\u56fe\u7279\u70b9\u3002 \u65b9\u6cd5\uff1a \u8be5\u75c5\u4f8b\u7cfb\u5217\u7814\u7a76\u5206\u67902021\u5e744\u6708\u81f32023\u5e744\u6708\u5728\u53a6\u95e8\u5927\u5b66\u9644\u5c5e\u4e2d\u5c71\u533b\u9662\u55d3\u97f3\u95e8\u8bca\u9996\u8bca\u3001\u6700\u7ec8\u786e\u8bcaALS\u76847\u4f8b\u60a3\u8005\uff3b\u7537\u60272\u4f8b\uff0c\u5973\u60275\u4f8b\uff1b\u5e74\u9f84\u4e3a43~76\uff0860.85\u00b113.18\uff09\u5c81\uff3d\u7684\u5589\u90e8\u75c7\u72b6\u3001\u4f53\u5f81\uff08\u9891\u95ea\u5589\u955c\u3001\u541e\u54bd\u5589\u955c\uff09\u3001\u58f0\u5b66\u8bc4\u4f30\u53ca\u5589\u808c\u7535\u56fe\u8d44\u6599\u3002\u91c7\u7528\u63cf\u8ff0\u6027\u65b9\u6cd5\u8fdb\u884c\u5206\u6790\u3002 \u7ed3\u679c\uff1a \u24607\u4f8b\u60a3\u8005\u65e2\u5f80\u5747\u5728\u8033\u9f3b\u54bd\u5589\u79d1\u5c31\u8bca2\u6b21\u4ee5\u4e0a\uff08\u4e2d\u4f4d\u6b21\u65703.57\u6b21\uff09\uff0c\u786e\u8bca\u65f6\u95f4\u4e3a12.28\u4e2a\u6708\u3002\u5c31\u8bca\u65f6\u4e3b\u8bc9\u4e3b\u8981\u4e3a\uff1a\u58f0\u97f3\u5636\u54d1\u3001\u53d1\u58f0\u8d39\u529b\u3001\u53d1\u58f0\u75b2\u52b3\u3001\u541e\u54bd\u5f02\u7269\u611f\u6216\u541e\u54bd\u56f0\u96be\u3001\u547c\u5438\u4e0d\u7545\u53ca\u8bf4\u8bdd\u542b\u7cca\u7b49\u3002\u2461\u5589\u808c\u7535\u56fe\uff1a7\u4f8b\u4e2d4\u4f8b\u63d0\u793a\u4e3a\u795e\u7ecf\u6e90\u6027\u635f\u5bb3\uff0c\u4e14\u5747\u4e3a\u53cc\u4fa7\uff0c3\u4f8b\u68c0\u67e5\u6b63\u5e38\uff1b3\u4f8b\u53d1\u73b0\u81ea\u53d1\u7535\u4f4d\u8005\u5747\u51fa\u73b0\u57286\u4e2a\u6708\u4ee5\u4e0a\uff0c\u6700\u957f\u8005\u8fbe24\u4e2a\u6708\uff1b3\u4f8b\u53d1\u73b0\u8fdb\u884c\u6027\u5931\u795e\u7ecf\u635f\u5bb3\u548c\u6162\u6027\u518d\u751f\u5e76\u5b58\uff0c2\u4f8b\u51fa\u73b0\u675f\u98a4\u7535\u4f4d\u3002\u2462\u9891\u95ea\u5589\u955c\uff1a7\u4f8b\u60a3\u8005\u5747\u51fa\u73b0\u53cc\u4fa7\u58f0\u5e26\u8fd0\u52a8\u4e0d\u5bf9\u79f0\u548c\u58f0\u95e8\u95ed\u5408\u4e0d\u5168\uff084\u4f8b\u5782\u76f4\u9762\uff0c3\u4f8b\u6c34\u5e73\u9762\uff09\uff0c5\u4f8b\u58f0\u5e26\u677e\u5f1b\uff0c3\u4f8b\u53cc\u4fa7\u58f0\u5e26\u8fd0\u52a8\u51cf\u5f31\uff0c1\u4f8b\u5355\u4fa7\u58f0\u5e26\u8fd0\u52a8\u51cf\u5f31\u3002\u541e\u54bd\u5589\u955c\uff1a7\u4f8b\u60a3\u8005\u5747\u663e\u793a\u6709\u8f7b-\u91cd\u5ea6\u4e0d\u7b49\u7684\u541e\u54bd\u529f\u80fd\u969c\u788d\uff0c3\u4f8b\u60a3\u8005\u8f6f\u816d\u95ed\u5408\u4e0d\u5168\uff0c\u8fdb\u98df\u540e\u4f1a\u538c\u8c37\u53ca\u68a8\u72b6\u7a9d\u5747\u6709\u8f7b\u5ea6-\u91cd\u5ea6\u4e0d\u7b49\u7684\u98df\u7269\u6b8b\u7559\uff0c1\u4f8b\u89c1\u6e17\u6f0f\uff0c1\u4f8b\u89c1\u8bef\u5438\u3002 \u7ed3\u8bba\uff1a \u9996\u53d1\u75c7\u72b6\u4e3a\u5589\u529f\u80fd\u5f02\u5e38\u7684\u60a3\u8005\uff0c\u5f53\u9891\u95ea\u5589\u955c\u53d1\u73b0\u58f0\u5e26\u8fd0\u52a8\u529f\u80fd\u5f02\u5e38\u7279\u522b\u662f\u58f0\u95e8\u95ed\u5408\u4e0d\u5168\u540c\u65f6\u4f34\u6709\u541e\u54bd\u5589\u955c\u4e0b\u541e\u54bd\u529f\u80fd\u5f02\u5e38\u65f6\uff0c\u9700\u8b66\u60d5ALS\u7684\u53ef\u80fd\uff0c\u5589\u808c\u7535\u56fe\u68c0\u67e5\u53d1\u73b0\u53cc\u4fa7\u795e\u7ecf\u6e90\u6027\u635f\u5bb3\u3001\u81ea\u53d1\u7535\u4f4d\u957f\u65f6\u95f4\u6301\u7eed\u5b58\u5728\u3001\u81ea\u53d1\u7535\u4f4d\u548c\u5bbd\u5927\u8fd0\u52a8\u5355\u4f4d\u7535\u4f4d\uff08motor unit potential\uff0cMUP\uff09\u5e76\u5b58\u4ee5\u53ca\u675f\u98a4\u7535\u4f4d\u7684\u51fa\u73b0\uff0c\u6709\u52a9\u4e8e\u65e9\u671f\u53d1\u73b0\u8bca\u65adALS\u3002."

Although acoustic voice analysis can detect phonatory alterations in ALS, its ability to differentiate clinical phenotypes remains limited. This study investigated whether biomechanical voice parameters provide complementary information for characterizing bulbar involvement across bulbar-onset ALS (ALS-B) and spinal-onset ALS (ALS-S) and explored their association with clinical and functional measures. Methods: This cross-sectional observational study included 50 patients with ALS (20 ALS-B, 30 ALS-S) and 50 controls with non-neurological voice disorders. Sustained vowel phonation was analyzed using acoustic measures and biomechanical voice parameters derived from a standardized model of vocal fold vibration. Perceptual voice severity was assessed using the GRBAS scale, while functional status was evaluated with the ALS Functional Rating Scale-Revised (ALSFRS-R) and the Barthel Index. Associations with clinical measures were explored in secondary analyses. Results: Compared with controls, ALS patients showed significant differences in acoustic measures and several biomechanical parameters related to glottal closure and vibratory stability. Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability. Unexpectedly, ALS-B showed greater perceptual voice severity and higher Barthel Index scores than ALS-S, while no differences were observed in global ALSFRS-R total scores. Conclusions: Biomechanical voice analysis appears to capture physiologically meaningful alterations in vocal fold function in ALS and provides complementary information for characterizing bulbar motor involvement across clinical phenotypes, particularly ALS-B disease. When combined with acoustic and clinical assessments, this approach may enhance the evaluation of bulbar involvement and functional status in ALS."

We aim to describe the most frequent otolaryngology (ORL) complaints and voice disturbances in patients with bulbar onset ALS. Retrospective cohort study. Single-center study with combined ORL and ALS clinic evaluation. Patients with a confirmed diagnosis of ALS following an ORL visit and who underwent comprehensive voice assessments between January 2021 and January 2023. Objective voice assessments. Glottal functional index (GFI), voice handicap index (VHI), reflux system index (RSI), and voice quality characteristics such as shimmer, jitter, maximum phonation time (MPT), and other essential parameters were assessed. One hundred and thirty-three patients (age 62.17\u00a0\u00b1\u00a010.79, 54.48% female) were included. Three patients were referred from the ORL department to the ALS clinic.

As interest in speech analysis grows, distinguishing between conditions becomes critical for reliable diagnosis and assessment. This pilot study explores speech biosignatures in two distinct neurodegenerative conditions: (1) mild traumatic brain injuries (eg, concussions) and (2) Parkinson disease (PD) as the neurodegenerative condition. The study included speech samples from 235 participants (97 concussed and 94 age-matched healthy controls, 29 PD and 15 healthy controls) for the PaTaKa test and 239 participants (91 concussed and 104 healthy controls, 29 PD and 15 healthy controls) for the Sustained Vowel (/ah/) test. Age-matched healthy controls were used. Young age-matched controls were used for concussion and respective age-matched controls for neurodegenerative participants (15 healthy samples for both tests). Data augmentation with noise was applied to balance small datasets for neurodegenerative and healthy controls. Machine learning models (support vector machine, decision tree, random forest, and Extreme Gradient Boosting) were employed using 37 temporal and spectral speech features. A 5-fold stratified cross-validation was used to evaluate classification performance. For the PaTaKa test, classifiers performed well, achieving F 1-scores above 0.9 for concussed versus healthy and concussed versus neurodegenerative classifications across all models. Initial tests using the original dataset for neurodegenerative versus healthy classification yielded very poor results, with F 1-scores below 0.2 and accuracy under 30% (eg, below 12 out of 44 correctly classified samples) across all models. This underscored the need for data augmentation, which significantly improved performance to 60%-70% (eg, 26-31 out of 44 samples) accuracy. In contrast, the Sustained Vowel test showed mixed results; F 1-scores remained high (more than 0.85 across all models) for concussed versus neurodegenerative classifications but were significantly lower for concussed versus healthy (0.59-0.62) and neurodegenerative versus healthy (0.33-0.77), depending on the model. This study highlights the potential of speech features as biomarkers for neurodegenerative conditions. The PaTaKa test exhibited strong discriminative ability, especially for concussed versus neurodegenerative and concussed versus healthy tasks, whereas challenges remain for neurodegenerative versus healthy classification. These findings emphasize the need for further exploration of speech-based tools for differential diagnosis and early identification in neurodegenerative health."

The aims were to (a) delineate temporal oral DDK deficits relating to the neuromotor pathology of ALS and (b) identify the optimal task-feature combinations to detect speech impairment in ALS. Mandibular myoelectric, kinematic, and acoustic data were acquired from 13 individuals with ALS and 10 healthy controls producing three alternating motion rate tasks and one sequential motion rate task. Twenty-seven features were extracted from the multimodal data, characterizing three temporal constructs: duration/rate, variability, and coordination. The disease impacts on these features were assessed across tasks, and the task eliciting the greatest disease-related change was identified for each feature. Such \"optimal\" task-feature combinations were fed into logistic regression to differentiate individuals with ALS from healthy controls. Temporal deficits in ALS were characterized by (a) increased duration and variability and reduced coordination of jaw muscle activities, (b) increased duration and variability and altered temporal symmetry of jaw velocity profile, (c) increased muscle-burst-to-peak-velocity duration, and (d) increased motion-to-voice onset duration. These temporal features were differentially affected across tasks. The optimal task-feature combinations, which were further clustered into three composite factors reflecting temporal variability, coarser-grained duration, and finer-grained duration, differentiated ALS from controls with an F1 score of 0.86 (precision = 1.00, recall = 0.75). Temporal oral DDK deficits are likely attributed to a hierarchy of interrelated neurophysiological and biomechanical factors associated with the neuromotor pathology of ALS. These deficits, as assessed crossmodally, provide previously unavailable insights into the multifaceted timing impairment of oromotor performance in ALS. The optimal task-feature combinations targeting these deficits show promise as quantitative markers for (early) detection of speech impairment in ALS."

The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech\u2011derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1\u2011weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices.

However, detection can be confounded due to factors like fatigue and testing anxiety. Cumulus neuroscience developed NeuLogiq(R), a multi-modal neurocognitive platform that can be used in clinic or at home, providing an ecologically valid measure of cognition. This study examined the feasibility and usability of NeuLogiq in plwALS, plwFTD, and controls, and compared performance on gold standard neuropsychological assessments with corresponding NeuLogiq digital assessments. Over 8 months, plwALS (n\u2009=\u200911), plwFTD (n\u2009=\u20097), and matched healthy controls (n\u2009=\u200910) completed longitudinal full neuropsychological assessment, as well as three 25-minute NeuLogiq Platform sessions every 2 weeks in their homes. Participants adhered well to the study schedule, conducting over 32/54 sessions on average. All groups rated usability in the 'good' or 'excellent' range and had\u2009>\u200980% complete data. Baseline group differences were detectable on both NeuLogiq digital assessments and benchmark neuropsychological assessments of similar cognitive domains. Longitudinal mixed effects models found that the ALS group showed decline on NeuLogiq measures of emotion recognition and speech fluency. These findings suggest that the NeuLogiq platform is feasible and usable for plwALS and plwFTD, and can identify cognitive deficits to a similar extent as benchmark assessments over time."

In this study, we reconstruct the developmental trajectory of cultured cortical networks derived from SOD1G93A mouse embryos using a multimodal approach, by combining morphometric, electrophysiological, pharmacological, molecular, computational, and machine-learning techniques. We prove that ALS neurons fail to acquire mature polarization and connectivity, displaying a transient phase of hyperexcitability that precedes a progressive collapse of network organization. Astrocytic dysfunction emerges early and impairs synchronization, establishing a causal link between glial dysfunction and neuronal instability. The analysis of synaptic transmission reveals an excitatory bias followed by maladaptive inhibitory recruitment and GABA/glutamate co-release, causing fragmented and inefficient network topologies. Finally, in silico modelling identified deficient intrinsic adaptation as a key driver of hyperexcitability. Together, our findings position ALS as a developmentally rooted disorder of cultured cortical network homeostasis, driven by glial, synaptic, and intrinsic adaptation failures. By demonstrating that cortical dysfunction is embedded before degeneration, this work provides a unifying framework connecting early network instability to disease progression and establishes electrophysiological network signatures, detected by machine learning classifiers, as candidate biomarkers for early diagnosis and therapeutic screening."

We included observational studies that applied sEMG to individuals diagnosed with ALS, with or without comparison to healthy controls, and without restrictions on publication year. The analyses included signals recorded at rest and during voluntary contractions, with or without the use of biofeedback. Most studies employed conventional or high-density surface electrodes, with sampling frequencies ranging from 500 Hz to 3000 Hz. The results showed that the primary parameters assessed were muscle fatigue, fasciculation patterns, the number of motor units (MUNE/MUNIX), motor unit firing rates, and signal complexity. These parameters demonstrated sensitivity to disease progression and may contribute to early diagnosis, phenotypic stratification, and functional monitoring of ALS. Additionally, the studies highlighted the increasing use of advanced computational approaches, such as machine learning, for feature extraction and automated classification. In conclusion, sEMG is a promising tool for functional assessment in ALS, with the potential to improve diagnostic accuracy and support new therapeutic strategies based on electrophysiological biomarkers. However, despite technological advances, the included studies displayed substantial methodological heterogeneity and limited protocol standardization. Integration with other neurophysiological modalities also remains underexplored, despite its significant clinical potential."

The primary aim of this translational pilot study was to identify a disease-specific, TDP-43-related, gene-microRNA (miRNA) signature in peripheral blood mononuclear cells (PBMCs) of ALS patients with potential diagnostic value. To this end, we first identified differentially expressed disease-specific genes (dsDEGs) using a TDP-43-based rat model of ALS, generated by stereotaxic infusion of full-length (FL) TAR DNA-binding protein 43 (TDP-43) into the motor cortex. Transcriptomic profiling of the motor cortex revealed candidate dsDEGs, which were subsequently validated by RT-qPCR in motor cortex, spinal cord, and PBMCs from the same animals. To assess translational relevance, expression levels of these dsDEGs were analyzed in PBMCs from early- to mid-stage ALS patients and matched healthy controls, while disease specificity was evaluated using Parkinson's disease (PD) samples. In parallel, conserved miRNAs predicted to target the identified dsDEGs were examined in both rat and human PBMCs. Five dsDEGs, Mctp1, Penk, Mt2A, Drd1, and Rasgrp2, were consistently dysregulated across central and peripheral tissues in the TDP-43 rat model. RT-qPCR analysis of human PBMCs confirmed significant and selective dysregulation of these genes in ALS, but not in PD, supporting disease specificity. Moreover, exposure of human neuroblastoma cells and healthy PBMCs to TDP-43 recapitulated the ALS-like expression changes. Computational and experimental analyses identified seven conserved miRNAs targeting these dsDEGs, of which four were significantly downregulated in ALS PBMCs, supporting a coordinated regulatory network. Receiver operating characteristic (ROC) analyses demonstrated strong discriminative performance for both the gene signature (AUC 0.87-1.00) and the associated miRNAs (AUC 0.95-1.00). Together, these findings define a novel PBMC-based gene-miRNA signature that mirrors central ALS pathology and shows high diagnostic accuracy and disease specificity, highlighting its potential as a minimally invasive biomarker for ALS."

The absence of specific diagnostic biomarkers leads to diagnostic delays, hindering early intervention and management. This review provides a critical appraisal of fluid-based biomarkers for ALS across multiple sources-cerebrospinal fluid (CSF), blood, urine, saliva, and tears-with emphasis on their diagnostic and prognostic potential, limitations, and readiness for clinical translation. While neurofilaments (NfL, pNfH) are well-established as sensitive indicators of neuroaxonal injury and are increasingly used as prognostic and pharmacodynamic markers in clinical trials, they lack disease specificity. Biomarkers reflecting ALS-specific pathology, such as TDP-43 species and C9orf72 dipeptide repeat proteins (DPRs), show promise but remain in early validation stages with limited multicenter data. Emerging markers from non-invasive sources (urine p75ECD, salivary chromogranin A, tear metabolomics) offer potential for repeated sampling but require rigorous external validation before clinical adoption. To address current gaps, we introduce a standardized evidence grading framework (Tier 1-3) and a comprehensive reporting template for biomarker studies, including explicit performance metrics (AUC, sensitivity, specificity, confidence intervals) and validation status. We also propose minimum reporting standards for study design, pre-analytical variables, and statistical rigor, modeled on REMARK guidelines. A roadmap for biomarker validation and a cross-fluid comparison matrix are provided to guide future research. Despite considerable progress, significant challenges remain, including biological heterogeneity, pre-analytical variability, and insufficient external validation. Future efforts should prioritize multicenter prospective studies, assay harmonization, ethical frameworks for early diagnosis, and integration of emerging technologies such as artificial intelligence and digital twins. Fluid-based biomarkers, while not yet replacing clinical evaluation, are essential tools for accelerating drug development, enabling patient stratification, and moving toward personalized medicine in ALS."

This study aims to explore the utility of peripheral immune cells and glycosylation indices as potential diagnostic biomarkers for ALS to enhance the accuracy and efficiency of early ALS diagnosis. This retrospective study included 54 ALS patients diagnosed in our hospital from June 2023 to October 2024, along with 54 healthy controls. Blood samples and laboratory data, including levels of peripheral immune cells and glycosylation indices, were collected from both groups. Through logistic regression, random forest models, receiver operating characteristic (ROC) curve analysis, and SHAP interpretability analysis, the predictive abilities and clinical significance of each candidate indicator were screened and evaluated. Notable disparities were detected in age, leukocyte count, monocyte levels, glycated haemoglobin A1c (HbA1c), and haemoglobin glycation index (HGI) between the control and ALS groups (all P < 0.05). Logistic regression analysis revealed that age (OR = 1.114) and monocyte (OR = 3.174) were risk factors for ALS, while leukocyte (OR = 0.533) and HbA1c (OR = 0.069) were protective factors. The random forest algorithm, ranked by decreasing importance, showed that leukocyte, HGI, monocyte, and HbA1c level all influenced ALS. Using these indicators to predict ALS resulted in a false-positive rate of 18% and a false-negative rate of 6%. ROC curve analysis indicated that the combined use of leukocyte, monocyte, HbA1c level, and HGI provided the highest diagnostic value for ALS (AUC = 0.774), which was higher than that of any individual indicator (all P < 0.05). SHAP analysis visualization demonstrated that increased monocyte and decreased leukocyte, HGI, and HbA1c level were all associated with an increased risk of ALS onset, ranked in descending order of feature importance as monocyte, leukocyte, HGI, and HbA1c. Peripheral blood white blood cells, monocytes, HbA1c, and HGI can serve as potential diagnostic biomarkers for ALS. Combined detection can improve the diagnostic accuracy of ALS, facilitating early diagnosis and intervention, and ultimately improving patient prognosis.

This retrospective study included 54 ALS patients diagnosed in our hospital from June 2023 to October 2024, along with 54 healthy controls. Blood samples and laboratory data, including levels of peripheral immune cells and glycosylation indices, were collected from both groups. Through logistic regression, random forest models, receiver operating characteristic (ROC) curve analysis, and SHAP interpretability analysis, the predictive abilities and clinical significance of each candidate indicator were screened and evaluated. Notable disparities were detected in age, leukocyte count, monocyte levels, glycated haemoglobin A1c (HbA1c), and haemoglobin glycation index (HGI) between the control and ALS groups (all P < 0.05). Logistic regression analysis revealed that age (OR = 1.114) and monocyte (OR = 3.174) were risk factors for ALS, while leukocyte (OR = 0.533) and HbA1c (OR = 0.069) were protective factors. The random forest algorithm, ranked by decreasing importance, showed that leukocyte, HGI, monocyte, and HbA1c level all influenced ALS. Using these indicators to predict ALS resulted in a false-positive rate of 18% and a false-negative rate of 6%. ROC curve analysis indicated that the combined use of leukocyte, monocyte, HbA1c level, and HGI provided the highest diagnostic value for ALS (AUC = 0.774), which was higher than that of any individual indicator (all P < 0.05). SHAP analysis visualization demonstrated that increased monocyte and decreased leukocyte, HGI, and HbA1c level were all associated with an increased risk of ALS onset, ranked in descending order of feature importance as monocyte, leukocyte, HGI, and HbA1c. Peripheral blood white blood cells, monocytes, HbA1c, and HGI can serve as potential diagnostic biomarkers for ALS. Combined detection can improve the diagnostic accuracy of ALS, facilitating early diagnosis and intervention, and ultimately improving patient prognosis. Further validation in cohorts including disease controls is required to confirm specificity."

This study aimed to investigate the relationship between clinical dysphagia assessment tools (EAT-10, GUSS, RSST, and sialorrhea severity) and videofluoroscopic swallowing study (VFSS) findings in patients with ALS. Materials and Methods: This retrospective observational study included 60 patients with ALS classified as spinal-onset (n = 38) or bulbar-onset (n = 22). Relationships between clinical assessments and VFSS findings were analysed using Spearman correlation analysis. Exploratory multivariable regression and receiver operating characteristic (ROC) analyses were performed to evaluate associations and aspiration risk discrimination. Results: Strong negative correlations were observed between PAS-Liquid and RSST and GUSS scores, whereas EAT-10 showed a strong positive correlation (all p < 0.001). ROC analyses demonstrated good discriminative ability for aspiration risk for GUSS (AUC = 0.89), RSST (AUC = 0.88), and EAT-10 (AUC = 0.82). Patients with bulbar-onset ALS demonstrated higher penetration-aspiration severity and lower functional oral intake. Conclusions: Clinical dysphagia assessment tools showed significant associations with instrumental swallowing findings in ALS. GUSS and RSST demonstrated good discriminative ability for aspiration risk and may be clinically useful bedside screening tools. However, instrumental swallowing assessment remains essential whenever feasible."

Recent work has demonstrated highly accurate intracortical BCIs for speech and cursor control, but two critical capabilities needed for practical viability were unmet: independent at-home operation without researcher assistance and reliable long-term performance supporting accurate speech and cursor decoding. Here we demonstrate the independent and near-daily use of a multimodal BCI with novel brain-to-text speech and computer cursor decoders by a man with paralysis and severe dysarthria due to amyotrophic lateral sclerosis. Over nearly 2\u2009years, the participant used the BCI for more than 3,800\u2009h at home with no researchers present to maintain rich interpersonal communication with his family and friends, independently control his personal computer and sustain full-time employment-despite being paralyzed. He communicated 183,060 sentences-totaling 1,960,163 words-at an average rate of 56 words per minute. He labeled 92% of sentences as being decoded at least mostly correctly. In formal quantifications of performance where he was asked to say words presented on a screen, attempted speech was consistently decoded with more than 99% word accuracy (125,000 word vocabulary). The participant also used the speech BCI as keyboard input and the cursor BCI as mouse input to control his personal computer, enabling him to send text messages and emails and to browse the internet. These results demonstrate that intracortical BCIs have the potential to support independent use in the home, marking a critical step toward practical assistive technology for people with severe motor impairment."

This study evaluated a Praat-based script that estimates global speech timing by detecting syllable nuclei via amplitude dips. Speaking rate (syllables/total duration) and articulation rate (syllables/speaking time) were measured manually and with an automated script across speakers with multiple sclerosis (MS), Parkinson's disease (PD), and healthy controls. Sixty participants (20 per group) completed sentence, paragraph, and monologue tasks (N\u2009=\u2009180 recordings). Default script parameters were compared to an optimized version with manually tuned dip thresholds. Analyses included error metrics, linear mixed-effects models, and generalizability analysis. Automated speaking rate measures showed strong correlations with manual measures across all groups and tasks (r\u2009=\u20090.623-0.998). However, default automated estimates underestimated both speaking and articulation rates, especially in clinical speakers and for the monologue task. Articulation rate was more sensitive to the measurement method, which accounted for nearly half of the total variance. Optimization of the Praat script parameters reduced proportional error by \u223c60%, with varying effects across groups. Findings suggest that optimized automated methods can improve measurement accuracy, but population- and task-specific challenges persist, especially for articulation rate in MS and PD speakers."

The absence of specific diagnostic biomarkers leads to diagnostic delays, hindering early intervention and management. This review provides a critical appraisal of fluid-based biomarkers for ALS across multiple sources-cerebrospinal fluid (CSF), blood, urine, saliva, and tears-with emphasis on their diagnostic and prognostic potential, limitations, and readiness for clinical translation. While neurofilaments (NfL, pNfH) are well-established as sensitive indicators of neuroaxonal injury and are increasingly used as prognostic and pharmacodynamic markers in clinical trials, they lack disease specificity. Biomarkers reflecting ALS-specific pathology, such as TDP-43 species and C9orf72 dipeptide repeat proteins (DPRs), show promise but remain in early validation stages with limited multicenter data. Emerging markers from non-invasive sources (urine p75ECD, salivary chromogranin A, tear metabolomics) offer potential for repeated sampling but require rigorous external validation before clinical adoption. To address current gaps, we introduce a standardized evidence grading framework (Tier 1-3) and a comprehensive reporting template for biomarker studies, including explicit performance metrics (AUC, sensitivity, specificity, confidence intervals) and validation status. We also propose minimum reporting standards for study design, pre-analytical variables, and statistical rigor, modeled on REMARK guidelines. A roadmap for biomarker validation and a cross-fluid comparison matrix are provided to guide future research. Despite considerable progress, significant challenges remain, including biological heterogeneity, pre-analytical variability, and insufficient external validation. Future efforts should prioritize multicenter prospective studies, assay harmonization, ethical frameworks for early diagnosis, and integration of emerging technologies such as artificial intelligence and digital twins. Fluid-based biomarkers, while not yet replacing clinical evaluation, are essential tools for accelerating drug development, enabling patient stratification, and moving toward personalized medicine in ALS."

However, detection can be confounded due to factors like fatigue and testing anxiety. Cumulus neuroscience developed NeuLogiq(R), a multi-modal neurocognitive platform that can be used in clinic or at home, providing an ecologically valid measure of cognition. This study examined the feasibility and usability of NeuLogiq in plwALS, plwFTD, and controls, and compared performance on gold standard neuropsychological assessments with corresponding NeuLogiq digital assessments.

In this study, we reconstruct the developmental trajectory of cultured cortical networks derived from SOD1G93A mouse embryos using a multimodal approach, by combining morphometric, electrophysiological, pharmacological, molecular, computational, and machine-learning techniques. We prove that ALS neurons fail to acquire mature polarization and connectivity, displaying a transient phase of hyperexcitability that precedes a progressive collapse of network organization. Astrocytic dysfunction emerges early and impairs synchronization, establishing a causal link between glial dysfunction and neuronal instability. The analysis of synaptic transmission reveals an excitatory bias followed by maladaptive inhibitory recruitment and GABA/glutamate co-release, causing fragmented and inefficient network topologies. Finally, in silico modelling identified deficient intrinsic adaptation as a key driver of hyperexcitability. Together, our findings position ALS as a developmentally rooted disorder of cultured cortical network homeostasis, driven by glial, synaptic, and intrinsic adaptation failures. By demonstrating that cortical dysfunction is embedded before degeneration, this work provides a unifying framework connecting early network instability to disease progression and establishes electrophysiological network signatures, detected by machine learning classifiers, as candidate biomarkers for early diagnosis and therapeutic screening."

We included observational studies that applied sEMG to individuals diagnosed with ALS, with or without comparison to healthy controls, and without restrictions on publication year. The analyses included signals recorded at rest and during voluntary contractions, with or without the use of biofeedback. Most studies employed conventional or high-density surface electrodes, with sampling frequencies ranging from 500 Hz to 3000 Hz. The results showed that the primary parameters assessed were muscle fatigue, fasciculation patterns, the number of motor units (MUNE/MUNIX), motor unit firing rates, and signal complexity. These parameters demonstrated sensitivity to disease progression and may contribute to early diagnosis, phenotypic stratification, and functional monitoring of ALS. Additionally, the studies highlighted the increasing use of advanced computational approaches, such as machine learning, for feature extraction and automated classification. In conclusion, sEMG is a promising tool for functional assessment in ALS, with the potential to improve diagnostic accuracy and support new therapeutic strategies based on electrophysiological biomarkers. However, despite technological advances, the included studies displayed substantial methodological heterogeneity and limited protocol standardization. Integration with other neurophysiological modalities also remains underexplored, despite its significant clinical potential."

The primary aim of this translational pilot study was to identify a disease-specific, TDP-43-related, gene-microRNA (miRNA) signature in peripheral blood mononuclear cells (PBMCs) of ALS patients with potential diagnostic value. To this end, we first identified differentially expressed disease-specific genes (dsDEGs) using a TDP-43-based rat model of ALS, generated by stereotaxic infusion of full-length (FL) TAR DNA-binding protein 43 (TDP-43) into the motor cortex. Transcriptomic profiling of the motor cortex revealed candidate dsDEGs, which were subsequently validated by RT-qPCR in motor cortex, spinal cord, and PBMCs from the same animals. To assess translational relevance, expression levels of these dsDEGs were analyzed in PBMCs from early- to mid-stage ALS patients and matched healthy controls, while disease specificity was evaluated using Parkinson's disease (PD) samples. In parallel, conserved miRNAs predicted to target the identified dsDEGs were examined in both rat and human PBMCs. Five dsDEGs, Mctp1, Penk, Mt2A, Drd1, and Rasgrp2, were consistently dysregulated across central and peripheral tissues in the TDP-43 rat model. RT-qPCR analysis of human PBMCs confirmed significant and selective dysregulation of these genes in ALS, but not in PD, supporting disease specificity. Moreover, exposure of human neuroblastoma cells and healthy PBMCs to TDP-43 recapitulated the ALS-like expression changes. Computational and experimental analyses identified seven conserved miRNAs targeting these dsDEGs, of which four were significantly downregulated in ALS PBMCs, supporting a coordinated regulatory network. Receiver operating characteristic (ROC) analyses demonstrated strong discriminative performance for both the gene signature (AUC 0.87-1.00) and the associated miRNAs (AUC 0.95-1.00). Together, these findings define a novel PBMC-based gene-miRNA signature that mirrors central ALS pathology and shows high diagnostic accuracy and disease specificity, highlighting its potential as a minimally invasive biomarker for ALS."

The primary aim of this translational pilot study was to identify a disease-specific, TDP-43-related, gene-microRNA (miRNA) signature in peripheral blood mononuclear cells (PBMCs) of ALS patients with potential diagnostic value. To this end, we first identified differentially expressed disease-specific genes (dsDEGs) using a TDP-43-based rat model of ALS, generated by stereotaxic infusion of full-length (FL) TAR DNA-binding protein 43 (TDP-43) into the motor cortex. Transcriptomic profiling of the motor cortex revealed candidate dsDEGs, which were subsequently validated by RT-qPCR in motor cortex, spinal cord, and PBMCs from the same animals. To assess translational relevance, expression levels of these dsDEGs were analyzed in PBMCs from early- to mid-stage ALS patients and matched healthy controls, while disease specificity was evaluated using Parkinson's disease (PD) samples. In parallel, conserved miRNAs predicted to target the identified dsDEGs were examined in both rat and human PBMCs. Five dsDEGs, Mctp1, Penk, Mt2A, Drd1, and Rasgrp2, were consistently dysregulated across central and peripheral tissues in the TDP-43 rat model. RT-qPCR analysis of human PBMCs confirmed significant and selective dysregulation of these genes in ALS, but not in PD, supporting disease specificity. Moreover, exposure of human neuroblastoma cells and healthy PBMCs to TDP-43 recapitulated the ALS-like expression changes. Computational and experimental analyses identified seven conserved miRNAs targeting these dsDEGs, of which four were significantly downregulated in ALS PBMCs, supporting a coordinated regulatory network. Receiver operating characteristic (ROC) analyses demonstrated strong discriminative performance for both the gene signature (AUC 0.87-1.00) and the associated miRNAs (AUC 0.95-1.00). Together, these findings define a novel PBMC-based gene-miRNA signature that mirrors central ALS pathology and shows high diagnostic accuracy and disease specificity, highlighting its potential as a minimally invasive biomarker for ALS."

This study aimed to investigate the relationship between clinical dysphagia assessment tools (EAT-10, GUSS, RSST, and sialorrhea severity) and videofluoroscopic swallowing study (VFSS) findings in patients with ALS. Materials and Methods: This retrospective observational study included 60 patients with ALS classified as spinal-onset (n = 38) or bulbar-onset (n = 22). Relationships between clinical assessments and VFSS findings were analysed using Spearman correlation analysis. Exploratory multivariable regression and receiver operating characteristic (ROC) analyses were performed to evaluate associations and aspiration risk discrimination. Results: Strong negative correlations were observed between PAS-Liquid and RSST and GUSS scores, whereas EAT-10 showed a strong positive correlation (all p < 0.001). ROC analyses demonstrated good discriminative ability for aspiration risk for GUSS (AUC = 0.89), RSST (AUC = 0.88), and EAT-10 (AUC = 0.82). Patients with bulbar-onset ALS demonstrated higher penetration-aspiration severity and lower functional oral intake. Conclusions: Clinical dysphagia assessment tools showed significant associations with instrumental swallowing findings in ALS. GUSS and RSST demonstrated good discriminative ability for aspiration risk and may be clinically useful bedside screening tools. However, instrumental swallowing assessment remains essential whenever feasible."

Recent work has demonstrated highly accurate intracortical BCIs for speech and cursor control, but two critical capabilities needed for practical viability were unmet: independent at-home operation without researcher assistance and reliable long-term performance supporting accurate speech and cursor decoding. Here we demonstrate the independent and near-daily use of a multimodal BCI with novel brain-to-text speech and computer cursor decoders by a man with paralysis and severe dysarthria due to amyotrophic lateral sclerosis. Over nearly 2\u2009years, the participant used the BCI for more than 3,800\u2009h at home with no researchers present to maintain rich interpersonal communication with his family and friends, independently control his personal computer and sustain full-time employment-despite being paralyzed. He communicated 183,060 sentences-totaling 1,960,163 words-at an average rate of 56 words per minute. He labeled 92% of sentences as being decoded at least mostly correctly. In formal quantifications of performance where he was asked to say words presented on a screen, attempted speech was consistently decoded with more than 99% word accuracy (125,000 word vocabulary). The participant also used the speech BCI as keyboard input and the cursor BCI as mouse input to control his personal computer, enabling him to send text messages and emails and to browse the internet. These results demonstrate that intracortical BCIs have the potential to support independent use in the home, marking a critical step toward practical assistive technology for people with severe motor impairment."

This study evaluated a Praat-based script that estimates global speech timing by detecting syllable nuclei via amplitude dips. Speaking rate (syllables/total duration) and articulation rate (syllables/speaking time) were measured manually and with an automated script across speakers with multiple sclerosis (MS), Parkinson's disease (PD), and healthy controls. Sixty participants (20 per group) completed sentence, paragraph, and monologue tasks (N\u2009=\u2009180 recordings). Default script parameters were compared to an optimized version with manually tuned dip thresholds. Analyses included error metrics, linear mixed-effects models, and generalizability analysis. Automated speaking rate measures showed strong correlations with manual measures across all groups and tasks (r\u2009=\u20090.623-0.998). However, default automated estimates underestimated both speaking and articulation rates, especially in clinical speakers and for the monologue task. Articulation rate was more sensitive to the measurement method, which accounted for nearly half of the total variance. Optimization of the Praat script parameters reduced proportional error by \u223c60%, with varying effects across groups. Findings suggest that optimized automated methods can improve measurement accuracy, but population- and task-specific challenges persist, especially for articulation rate in MS and PD speakers."

Recent reductions in global health funding have threatened TB control, making comprehensive assessment of TB, HIV-related TB, and drug-resistant TB burdens before these disruptions essential for shaping effective responses. The WHO End TB Strategy sets targets of a 95% reduction in TB deaths and a 90% reduction in TB incidence between 2015 and 2035. Using results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023, this study aims to assess the burden of TB and multidrug-resistant TB (MDR-TB) across 204 countries and territories, and to evaluate progress towards the WHO End TB incidence and mortality targets. We quantified TB mortality using the Cause of Death Ensemble modelling platform with global vital registration, surveillance, verbal autopsy, and minimally invasive tissue sampling data. For TB morbidity estimation, we simultaneously modelled incidence, prevalence, and mortality by age and sex using DisMod-MR 2.1. A population attributable fraction (PAF) approach was applied to stratify morbidity and mortality estimates by HIV and drug-resistance status. We also calculated disability-adjusted life-years (DALYs) as the sum of years of life lost and years lived with disability. For the risk factor analysis, a comparative risk assessment framework was used and PAFs were derived for alcohol use, smoking, and high fasting plasma glucose to determine the proportion of TB burden associated with these risk factors. In 2023, there were an estimated 9\u00b711 million (95% uncertainty interval 8\u00b704-10\u00b73) incident cases of all-form TB, 1\u00b722 million (0\u00b798-1\u00b749) deaths, and 54\u00b76 million (43\u00b78-65\u00b75) DALYs globally. HIV-related TB comprised 781\u2008000 (690\u2008000-879\u2008000) incident cases and 210\u2008000 (142\u2008000-279\u2008000) deaths, contributing 11\u00b70 million (7\u00b756-14\u00b73) DALYs. MDR-TB accounted for 466\u2008000 (198\u2008000-1\u2008080\u2008000) incident cases, 102\u2008000 (31\u2008700-238\u2008000) deaths, and 3\u00b796 million (1\u00b731-9\u00b701) DALYs. From 2015 to 2023, global all-form TB incidence rates declined by 19\u00b72% (17\u00b78-20\u00b75) and deaths declined by 22\u00b76% (4\u00b77-35\u00b77); declines were larger for drug-susceptible TB than for MDR-TB. Sub-Saharan Africa and south Asia had the highest mortality burdens in 2023; reductions in all-form TB incidence and mortality were uneven between 2000 and 2023, with limited progress in both measures in Latin America and the Caribbean. Removing smoking, alcohol use, and high fasting plasma glucose would reduce global TB deaths to 768\u2008000 (592\u2008000-970\u2008000) and DALYs to 34\u00b79 million (27\u00b78-43\u00b78) in 2023; MDR-TB deaths would decrease to 77\u2008200 (23\u2008400-183\u2008000) and DALYs to 3\u00b712 million (1\u00b703-7\u00b729). Global progress towards WHO End TB targets is disparate and fragile. Although many regions achieved meaningful gains, others have stagnated in recent years. The complexity of TB prevention is amplified by divergent MDR-TB trends, the persistent burden of HIV, and growing exposure to modifiable risk factors. Recent volatility in global health financing threatens to further destabilise this vulnerable epidemiological landscape; concerted action is urgently needed to temper disruptions and preserve progress.

These changes\u2014often subtle and requiring sophisticated extraction\u2014precede functional communicative decline and may provide a window for early diagnosis.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe clinical trajectory of Amyotrophic Lateral Sclerosis (ALS) is increasingly recognized to include a prolonged, clinically silent prodromal period. Quantitative analysis of vocal and speech motor control, utilizing surface electromyography (sEMG) and acoustic signal processing, identifies nuanced physiological patterns of decline\u2014specifically in phonatory stability, glottal tension, and articulatory precision\u2014that emerge before the manifestation of traditional clinical symptoms, offering a non-invasive, scalable biomarker for early detection.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic Lateral Sclerosis is traditionally viewed as a disorder of motor neuron degeneration characterized by progressive limb or bulbar weakness. However, emerging research into digital speech biomarkers indicates that bulbar involvement can be detected through non-invasive assessments during the prodromal phase. Current clinical standards, such as the ALS Functional Rating Scale-Revised (ALSFRS-R), lack the sensitivity to capture these subclinical neuromuscular changes. Digital voice analysis\u2014leveraging high-frequency acoustic data and biomechanical models of vocal fold vibration\u2014serves as a high-fidelity diagnostic instrument. The integration of artificial intelligence and machine learning pipelines allows for the automatic extraction of composite outcome measures that demonstrate clinical validity in differentiating ALS profiles from healthy aging and other neurodegenerative conditions. These metrics, such as articulatory rate, fundamental frequency variation, and glottal stability, act as objective markers of the underlying motor neuron pathology, potentially enabling earlier intervention and precision-based therapeutic monitoring.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Subclinical Detection:** Artificial intelligence frameworks can identify neuromuscular changes during the \"clinically silent prodromal stage\" before functional decline is apparent.\n*   **Biomechanical Precision:** Biomechanical voice parameters reflecting glottal tension and vocal fold stability are sensitive enough to differentiate clinical phenotypes (bulbar vs. spinal onset).\n*   **Multimodal Integration:** Combining facial sEMG and acoustic signals outperforms single-modality assessments in detecting early bulbar motor dysfunction.\n*   **Listener Effort (LE):** LE is a clinician-rated metric that captures meaningful change in dysarthria and shows potential as a responsive clinical trial endpoint.\n*   **Smartphone Utility:** Simple, smartphone-based assessment tasks (e.g., tongue lateralization or vowel phonation) correlate highly with laboratory-standard assessments, increasing access.\n*   **Stability of Biomarkers:** Despite disease progression, high-gamma cortical features in ECoG speech BCIs show long-term stability, suggesting durability for assistive interfaces.\n*   **Predictive Modeling:** Subject-specific prognostic models can now predict articulatory precision and ALSFRS-R speech subscores 30\u201390 days in advance.\n*   **Vocal Subtypes:** Unsupervised clustering reveals \"vocal profiles\" that transcend traditional diagnostic labels, indicating that voice features capture functional patterns of voice production across different disorders.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Objective digital biomarkers, particularly those derived from acoustic and biomechanical analyses, demonstrate superior sensitivity compared to standard clinical ratings for capturing early disease progression. Speech rate, vowel acoustics, and articulatory precision are identified as sensitive metrics for the detection of subclinical bulbar motor neuron degeneration.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic lateral sclerosis, though primarily recognized for motor neuron degeneration, presents with non-motor and subtle bulbar manifestations that often precede definitive diagnosis. The literature confirms that in 25% of ALS sufferers, speech disorders occur as prodromal symptoms of the disease. Consequently, there is an urgent need to leverage digital technology to identify these latent changes. As one study notes, speech rate appears to decline significantly before the diagnosis of ALS is confirmed. The physiological basis for these alterations is supported by neuroimaging, which indicates that reduced speaking and articulation rates were associated with thinning in both oral motor cortices. Furthermore, the granularity afforded by digital tools allows for the identification of changes before they reach clinical thresholds, as automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Voice serves as a latent, multimodal biomarker reflecting neurological, cardiopulmonary, and psychological states.\n*   Automated segmentation algorithms can now identify syllable and phoneme positions during oral diadochokinesis with over 90% accuracy, providing a basis for objective monitoring.\n*   Biomechanical voice analysis captures physiologically meaningful alterations in vocal fold function, offering complementary information that transcends traditional clinical diagnostic labels.\n*   Changes in speech and swallowing function can be monitored remotely using smartphone applications, potentially reducing the need for frequent clinical hospital visits.\n*   There is a significant need for better standardized tools, as current outcome measurements for speech and swallow are deemed clinically meaningful by only a minority of practitioners.\n*   Vowel acoustic features (e.g., Formant Centralization Ratio) provide insight into the shared brainstem neuromotor substrate of both speech and swallowing.\n*   Research confirms the existence of coherent vocal profiles across patients that do not strictly align with existing clinical diagnostic categories.\n*   Early intervention protocols are limited by current guideline gaps, underscoring the necessity of individual-level predictive modeling.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The literature demonstrates that while overt bulbar impairment is a feature of disease progression, advanced signal processing and neuroimaging provide evidence that cortical motor neuron degeneration is embedded in the brain architecture before the overt clinical manifestation of degeneration. Current digital platforms, including automated speech timing measures, allow for the identification of potential prognostic indicators in speech production that bypass the limitations of traditional, rater-dependent scales.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe early detection of ALS remains a clinical challenge due to the reliance on traditional neurological examinations, which often fail to capture subtle bulbar motor neuron degeneration. Research utilizing high-density neuroimaging and digital speech analysis suggests that cortical dysfunction is present before the transition to overt systemic degradation. Specifically, thinning of the oral motor cortex correlates with reduced oral motor function, serving as a sensitive marker for underlying neuronal instability. Longitudinal analysis of speech parameters, such as articulation rates, indicates that these measures capture bulbar decline with greater sensitivity than traditional scoring tools. Furthermore, advanced classification frameworks\u2014ranging from gene-miRNA signatures in PBMCs to machine learning-derived electrophysiological signatures\u2014are defining new diagnostic horizons. The shift toward non-invasive digital endpoints provides a scalable approach to monitor these subtle changes in the pre-symptomatic phase, offering a potential path for earlier intervention.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Thinning of the bilateral oral motor cortices is an anatomical precursor that maps directly to measurable decrements in oral motor function.\n*   Automated speaking and articulation rates provide a robust alternative to manually conducted assessments, which are prone to observer bias.\n*   Digital speech-derived measures demonstrate clear neuroanatomical correlations where standard bulbar subscores in the ALSFRS-R do not.\n*   The use of intracortical brain-computer interfaces (BCIs) has allowed for long-term monitoring, producing datasets with high word accuracy that validate the stability of speech-based tracking.\n*   Cortical dysfunction originates in a developmental trajectory in cultured cortical networks, suggesting that network collapse is a final stage of a long-standing process.\n*   The combination of digital endpoints (spirometry, accelerometry, and speech) yields high protocol adherence, supporting their future integration into standard clinical workflows.\n*   The identification of a gene-miRNA signature in PBMCs provides a molecular foundation that mirrors the central pathology of TDP-43 in ALS.\n*   Machine learning models are increasingly capable of identifying electrophysiological signatures in neuronal networks that predate overt degeneration.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

            "finalResponse": "Amyotrophic Lateral Sclerosis (ALS) is a disease that affects the nerve cells responsible for controlling muscles. Because these nerves also control the muscles in your throat, tongue, and lips, changes in how you speak can often be an early warning sign\u2014sometimes appearing before other more obvious symptoms, like arm or leg weakness.\n\nIn simple terms, researchers have found that voice and speech can act as a \"digital window\" into the health of these nerves. Here is a breakdown of what that means:\n\n* **Slowing Down:** Before a person is officially diagnosed with ALS, they may start speaking more slowly or having trouble with the precision of their movements (articulation) [ID: 40710301, 42333954].\n* **Hidden Changes:** These changes are often so subtle that a doctor listening to a patient might not notice them during a regular check-up. However, specialized computer programs can analyze acoustic data to catch these \"subclinical\" patterns\u2014meaning they pick up on declines that are happening under the surface [ID: 42137113, 40851280].\n* **Better Technology:** Scientists are now using smartphone apps and recording tools to track these changes remotely [ID: 42011674, 41360452]. This is useful because it provides an objective, scientific measurement that doesn't rely just on the doctor's opinion [ID: 42040341, 41829459].\n* **Why It Matters:** By tracking these voice \"biomarkers\" (measurable indicators), doctors hope to detect ALS much earlier than they do today [ID: 42329964]. If we can see the disease starting through speech patterns, it may open the door for earlier medical support and more effective monitoring of how a treatment is working [ID: 42137113, 41718496].\n\nEssentially, your voice is a complex machine involving many muscles. When those muscles start to lose their connection to the brain, your speech changes in specific, measurable ways that technology is now getting very good at identifying.",

These changes\u2014often subtle and requiring sophisticated extraction\u2014precede functional communicative decline and may provide a window for early diagnosis.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe clinical trajectory of Amyotrophic Lateral Sclerosis (ALS) is increasingly recognized to include a prolonged, clinically silent prodromal period. Quantitative analysis of vocal and speech motor control, utilizing surface electromyography (sEMG) and acoustic signal processing, identifies nuanced physiological patterns of decline\u2014specifically in phonatory stability, glottal tension, and articulatory precision\u2014that emerge before the manifestation of traditional clinical symptoms, offering a non-invasive, scalable biomarker for early detection.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic Lateral Sclerosis is traditionally viewed as a disorder of motor neuron degeneration characterized by progressive limb or bulbar weakness. However, emerging research into digital speech biomarkers indicates that bulbar involvement can be detected through non-invasive assessments during the prodromal phase. Current clinical standards, such as the ALS Functional Rating Scale-Revised (ALSFRS-R), lack the sensitivity to capture these subclinical neuromuscular changes. Digital voice analysis\u2014leveraging high-frequency acoustic data and biomechanical models of vocal fold vibration\u2014serves as a high-fidelity diagnostic instrument. The integration of artificial intelligence and machine learning pipelines allows for the automatic extraction of composite outcome measures that demonstrate clinical validity in differentiating ALS profiles from healthy aging and other neurodegenerative conditions. These metrics, such as articulatory rate, fundamental frequency variation, and glottal stability, act as objective markers of the underlying motor neuron pathology, potentially enabling earlier intervention and precision-based therapeutic monitoring.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Subclinical Detection:** Artificial intelligence frameworks can identify neuromuscular changes during the \"clinically silent prodromal stage\" before functional decline is apparent.\n*   **Biomechanical Precision:** Biomechanical voice parameters reflecting glottal tension and vocal fold stability are sensitive enough to differentiate clinical phenotypes (bulbar vs. spinal onset).\n*   **Multimodal Integration:** Combining facial sEMG and acoustic signals outperforms single-modality assessments in detecting early bulbar motor dysfunction.\n*   **Listener Effort (LE):** LE is a clinician-rated metric that captures meaningful change in dysarthria and shows potential as a responsive clinical trial endpoint.\n*   **Smartphone Utility:** Simple, smartphone-based assessment tasks (e.g., tongue lateralization or vowel phonation) correlate highly with laboratory-standard assessments, increasing access.\n*   **Stability of Biomarkers:** Despite disease progression, high-gamma cortical features in ECoG speech BCIs show long-term stability, suggesting durability for assistive interfaces.\n*   **Predictive Modeling:** Subject-specific prognostic models can now predict articulatory precision and ALSFRS-R speech subscores 30\u201390 days in advance.\n*   **Vocal Subtypes:** Unsupervised clustering reveals \"vocal profiles\" that transcend traditional diagnostic labels, indicating that voice features capture functional patterns of voice production across different disorders.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Objective digital biomarkers, particularly those derived from acoustic and biomechanical analyses, demonstrate superior sensitivity compared to standard clinical ratings for capturing early disease progression. Speech rate, vowel acoustics, and articulatory precision are identified as sensitive metrics for the detection of subclinical bulbar motor neuron degeneration.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic lateral sclerosis, though primarily recognized for motor neuron degeneration, presents with non-motor and subtle bulbar manifestations that often precede definitive diagnosis. The literature confirms that in 25% of ALS sufferers, speech disorders occur as prodromal symptoms of the disease. Consequently, there is an urgent need to leverage digital technology to identify these latent changes. As one study notes, speech rate appears to decline significantly before the diagnosis of ALS is confirmed. The physiological basis for these alterations is supported by neuroimaging, which indicates that reduced speaking and articulation rates were associated with thinning in both oral motor cortices. Furthermore, the granularity afforded by digital tools allows for the identification of changes before they reach clinical thresholds, as automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Voice serves as a latent, multimodal biomarker reflecting neurological, cardiopulmonary, and psychological states.\n*   Automated segmentation algorithms can now identify syllable and phoneme positions during oral diadochokinesis with over 90% accuracy, providing a basis for objective monitoring.\n*   Biomechanical voice analysis captures physiologically meaningful alterations in vocal fold function, offering complementary information that transcends traditional clinical diagnostic labels.\n*   Changes in speech and swallowing function can be monitored remotely using smartphone applications, potentially reducing the need for frequent clinical hospital visits.\n*   There is a significant need for better standardized tools, as current outcome measurements for speech and swallow are deemed clinically meaningful by only a minority of practitioners.\n*   Vowel acoustic features (e.g., Formant Centralization Ratio) provide insight into the shared brainstem neuromotor substrate of both speech and swallowing.\n*   Research confirms the existence of coherent vocal profiles across patients that do not strictly align with existing clinical diagnostic categories.\n*   Early intervention protocols are limited by current guideline gaps, underscoring the necessity of individual-level predictive modeling.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The literature demonstrates that while overt bulbar impairment is a feature of disease progression, advanced signal processing and neuroimaging provide evidence that cortical motor neuron degeneration is embedded in the brain architecture before the overt clinical manifestation of degeneration. Current digital platforms, including automated speech timing measures, allow for the identification of potential prognostic indicators in speech production that bypass the limitations of traditional, rater-dependent scales.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe early detection of ALS remains a clinical challenge due to the reliance on traditional neurological examinations, which often fail to capture subtle bulbar motor neuron degeneration. Research utilizing high-density neuroimaging and digital speech analysis suggests that cortical dysfunction is present before the transition to overt systemic degradation. Specifically, thinning of the oral motor cortex correlates with reduced oral motor function, serving as a sensitive marker for underlying neuronal instability. Longitudinal analysis of speech parameters, such as articulation rates, indicates that these measures capture bulbar decline with greater sensitivity than traditional scoring tools. Furthermore, advanced classification frameworks\u2014ranging from gene-miRNA signatures in PBMCs to machine learning-derived electrophysiological signatures\u2014are defining new diagnostic horizons. The shift toward non-invasive digital endpoints provides a scalable approach to monitor these subtle changes in the pre-symptomatic phase, offering a potential path for earlier intervention.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Thinning of the bilateral oral motor cortices is an anatomical precursor that maps directly to measurable decrements in oral motor function.\n*   Automated speaking and articulation rates provide a robust alternative to manually conducted assessments, which are prone to observer bias.\n*   Digital speech-derived measures demonstrate clear neuroanatomical correlations where standard bulbar subscores in the ALSFRS-R do not.\n*   The use of intracortical brain-computer interfaces (BCIs) has allowed for long-term monitoring, producing datasets with high word accuracy that validate the stability of speech-based tracking.\n*   Cortical dysfunction originates in a developmental trajectory in cultured cortical networks, suggesting that network collapse is a final stage of a long-standing process.\n*   The combination of digital endpoints (spirometry, accelerometry, and speech) yields high protocol adherence, supporting their future integration into standard clinical workflows.\n*   The identification of a gene-miRNA signature in PBMCs provides a molecular foundation that mirrors the central pathology of TDP-43 in ALS.\n*   Machine learning models are increasingly capable of identifying electrophysiological signatures in neuronal networks that predate overt degeneration.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

subject-specific prognostic model for speech predicts future articulatory precision and ALSFRS-R speech values accurately.\nThis demonstrates that our model can improve the diagnosis of bulbar dysfunction compared not only with clinicians, but also the methods published to date.\nIn some plwALS, we were able to demonstrate that automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring.\nspeech rate appears to decline significantly before the diagnosis of ALS is confirmed.\nautomated speech analyses are more

Begin with a clear Yes or No. Is the synthesis 100% veridical with the validated quotes? Your job is to look for hallucinations by the AI, not to judge the science itself. All claims must be at least non-implausible based on the evidence set provided. Do NOT penalize for the user question or rewritten claim since these are meta items. Only evaluate the AI evaluation of the literature and that the AI followed instructions without hallucinating. List and justify your judgements. Do not use markdown. DO NOT PENALIZE FOR THE USER QUERY WORDING OR REWRITE>>> THAT IS NOT PART OF THE ANSWER ... THAT IS THE QUESTION OR CLAIM EVALUATED.\nAssistant: Yes. The synthesis is 100% veridical with the provided validated quotes.\n\n1. The AI correctly identified that speech/voice biomarkers serve as early indicators in the prodromal phase of ALS. This is supported by ID 31629403, which states speech disorders occur as prodromal symptoms in 25% of cases, and ID 40710301, which notes speech rate declines before diagnosis.\n2. The AI accurately linked cortical thinning in the oral motor cortex to reduced articulation rates. This is explicitly supported by ID 42333954.\n3. The AI correctly asserted that digital speech analyses are more effective at detecting early changes than traditional clinical scales (like the ALSFRS-R). This is directly supported by ID 40851280.\n4. The AI cited the utility of biomechanical voice analysis and its ability to capture phenotype differentiation. This is supported by ID 41892827.\n5. All references provided are mapped to specific evidence IDs in the context, and there are no instances where the AI generated information outside of the provided module. The claims are logically consistent with the source material and accurately represent the provided literature.\n\n\n=============================\nUser Request: ANSWER IN THIS LANGUAGE --->>> Answer in English only.

We evaluated the feasibility of a multimodal home monitoring protocol in ALS. Methods: We conducted a 3-month prospective cohort study at the University Medical Center Utrecht, Netherlands, with monthly home assessments of spirometry, accelerometry, speech, and questionnaires on functioning. The primary outcome was protocol adherence, defined as percentage of completed assessments. Secondary outcomes included acceptability ((totally) agree, neutral, (totally) disagree), and perceived burden, ranging from 0 (no burden) to 10 (extremely burdensome). Exploratory analyses were performed to evaluate changes in digital endpoints using linear mixed-effects models. Findings: Fifty patients with ALS were included (January 2023 - June 2025), of whom 47 (94%) completed the 3-month follow-up. Overall adherence was 83.2% (95% CI 76.9-88.6) and did not differ across modalities (p\u2009=\u20090.75). Adherers did not differ from non-adherers in either demographic or disease characteristics. In month 3, 93.0% to 95.3% of patients considered monthly remote assessments as acceptable, with a mean burden score of 2.0 (95% CI 1.7 to 2.3); burden was highest for speech (2.5) and the lowest for questionnaires (1.5). Digital endpoints showed significant change over 3\u2009months (all p\u2009<\u20090.05). Interpretation: This study demonstrates good adherence and acceptability of a multimodal remote monitoring protocol. Digital endpoints offer an innovative approach to capturing disease progression. Future research should assess its long-term feasibility, added value, and integration alongside established clinical outcomes."

The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech\u2011derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1\u2011weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS."

Effective management of progressive communication disorders requires a personalized approach to deliver timely interventions tailored to the evolving profiles of communicative impairment, thereby supporting functional communication throughout the disease course. To this end, reliable tools capable of detecting and quantifying both disease-specific patterns of communicative impairment and within-disease phenotypic variability are urgently needed. This study leverages Artificial Intelligence and advanced data analytics to develop an acoustic-based framework for automated extraction of interpretable, clinically grounded speech markers to enable objective assessment and phenotyping of progressive communication disorders. Three groups of participants, including 14 individuals with amyotrophic lateral sclerosis (ALS) and 15 individuals with Parkinson's disease (PD), alongside 10 neurologically healthy controls, performed a standardized oral passage reading task, yielding 739 speech samples. Fifty acoustic features were extracted using an automated analytic pipeline and subsequently clustered into six interpretable composite markers. The clinical utility of these markers was evaluated with the recorded speech samples by examining their (1) associations with standardized metrics of cognitive, motor speech, and overall communicative functions, (2) efficacy for detecting and differentiating disease-specific communicative impairment patterns in ALS and PD using supervised machine learning, and (3) utility for within-disease phenotyping and stratification using unsupervised clustering analysis. The markers effectively (1) detected subtle subclinical changes across multiple domains prior to substantial declines in functional communication outcomes; (2) differentiated disease-specific patterns of communicative impairment (multiclass area under the curve > 0.90); and (3) identified subgroups with distinct speech profiles within each disease. The findings support the potential of the proposed framework as a clinically translatable, objective tool to facilitate early detection, differential diagnosis, and phenotyping of progressive communication disorders, ultimately advancing personalized, measurement-based care in neurodegenerative diseases."

A clinically grounded sEMG framework was developed, integrating a standardized, repeatable protocol with a novel analytic pipeline, to automatically extract 60 features from six craniofacial muscle groups during a set of motorically demanding but cognitively and linguistically less challenging oral diadochokinetic (DDK) tasks. Using this framework, 104 oral DDK recordings were acquired from 16 individuals with ALS-nine with overt bulbar symptoms (ALS+B) and seven without (ALS-B)-and 10 healthy controls (HCs). The sEMG features were clustered into 10 interpretable composite measures and validated by evaluating their (1) internal consistency using Cronbach's \u03b1 ; (2) associations with standardized functional outcomes and a biomechanical metric-stiffness-via mediation analysis; (3) discriminatory efficacy in distinguishing ALS+B and ALS-B from HC, as well as from each other, using machine learning classifications; and (4) robustness to common nonmotor confounders, including age, sex, and cognitive-linguistic impairments, through a comparison of discriminatory performance before and after adjustment for these factors. All composite measures exhibited (1) high internal consistency (Cronbach's \u03b1 = 0.89 \u00b1 0.071 ), (2) significant (or marginally significant) direct or stiffness-mediated indirect associations with the functional outcomes, and (3) consistently high discriminatory accuracy (0.82-0.85), both before and after adjustment for confounders.

Remote monitoring is an evolving mode of health status tracking. This survey aimed to establish SLT perspectives on ALS assessment regarding 1) the clinical meaningfulness of existing outcome measurement instruments 2) remote monitoring 3) usefulness of assessment devices for patient care and 4) bulbar function outcomes and measurement instruments useful for research studies. An online English-language survey was distributed internationally through gatekeepers and social media. Sixty-six SLTs responded from 13 countries. Current outcome measurement instruments were regarded as clinically meaningful in ALS by 35% for speech and 41% for swallow. Only 12% had access to remote monitoring, but 77% would like to avail of it, with 58% perceiving its potential to enhance care. Eighty-two percent deemed remote monitoring using digital patient-reported outcome measures (PROMs) useful. Speech intelligibility measurement was selected as the most useful communication outcome for remote monitoring (92%) and research (94%). SLTs agreed that speech intelligibility test software (72%), smart device apps (70%) and tongue pressure measurement devices (54%) are useful assessment equipment. SLTs want better measurement instruments for speech and swallow in ALS. They regarded technologies including remote monitoring incorporating digital PROMs as useful. Outcomes reflecting communication and swallow functional success level were deemed most useful. These survey findings can inform the selection of digital speech and swallow outcomes for ALS."

We tracked signal characteristics and decoding over 25 months in a participant with ALS to determine how high-gamma (HG, 70-170 Hz) activity changes over time and whether these changes affect offline speech decoding. We implanted two 8\u00d78 subdural ECoG grids over left sensorimotor cortex (SMC) in a participant with slowly progressive bulbar variant ALS. Across 25 months, the participant performed an overt syllable-repetition task (12 consonant-vowel tokens) during simultaneous ECoG and audio recording. We quantified HG activation ratio (ActR), spectral signal-to-noise ratio (SNR; HG/HF, where HF = 300-499 Hz), and peak z-scored HG responses. Speech acoustics were evaluated using first/second formants (F1/F2) and the triangular vowel space area (tVSA). Offline EEGNet-based decoders were assessed in two stages: models trained on post-implant months 1-6 were tested on months 7-25, while models trained on stabilized data (months 7-11) were tested on the remaining period (months 12-25). Electrode-level saliency assessed spatial contributions to decoding. Acoustic analyses showed a significant reduction in tVSA over two years (-44.6 Hz2/day; P < 10-7), consistent with mild intelligibility decline. Neural metrics (ActR and SNR) followed a biphasic trajectory: increasing during the first 6 months, after which ActR stabilized (0.041%/day; P = 0.13), and SNR declined gradually (-0.46%/day, P < 10- 4). The model trained on months 1-6 achieved 55.7% accuracy (chance: 8.33%), but performance declined over time (-0.019%/day; P = 2.1\u00d710-4). Conversely, the model trained on months 7-11 achieved higher accuracy (65.9%) on subsequent data with no significant temporal decline (P = 0.23). Speech-related HG features exhibited an initial unstable period followed by a long-term gradual SNR reduction, potentially reflecting disease progression. Models trained after signal stabilization generalized robustly to data recorded over a year later. These findings confirm that despite reduced absolute HG power and mild acoustic degradation of speech, cortical features remain stable enough to support durable ECoG speech BCIs without frequent recalibration. These findings will motivate future adaptive calibration algorithms that account for slow signal changes while leveraging stable spatial representations in ventral SMC. NCT03567213."

Although acoustic voice analysis can detect phonatory alterations in ALS, its ability to differentiate clinical phenotypes remains limited. This study investigated whether biomechanical voice parameters provide complementary information for characterizing bulbar involvement across bulbar-onset ALS (ALS-B) and spinal-onset ALS (ALS-S) and explored their association with clinical and functional measures. Methods: This cross-sectional observational study included 50 patients with ALS (20 ALS-B, 30 ALS-S) and 50 controls with non-neurological voice disorders. Sustained vowel phonation was analyzed using acoustic measures and biomechanical voice parameters derived from a standardized model of vocal fold vibration. Perceptual voice severity was assessed using the GRBAS scale, while functional status was evaluated with the ALS Functional Rating Scale-Revised (ALSFRS-R) and the Barthel Index. Associations with clinical measures were explored in secondary analyses. Results: Compared with controls, ALS patients showed significant differences in acoustic measures and several biomechanical parameters related to glottal closure and vibratory stability. Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability. Unexpectedly, ALS-B showed greater perceptual voice severity and higher Barthel Index scores than ALS-S, while no differences were observed in global ALSFRS-R total scores. Conclusions: Biomechanical voice analysis appears to capture physiologically meaningful alterations in vocal fold function in ALS and provides complementary information for characterizing bulbar motor involvement across clinical phenotypes, particularly ALS-B disease. When combined with acoustic and clinical assessments, this approach may enhance the evaluation of bulbar involvement and functional status in ALS."

The \"ALS-OPM\" classification is based on the onset region (O), the propagation of motor symptoms (P), and the degree of clinical upper (UMN) and/or lower (LMN) motor neuron dysfunction (M). An international ALS expert focus group was held in September 2025, followed by a consensus process through which revisions of the OPM classification were finalized. Onset (O1-4) identifies first motor symptoms as relating to the head (O1), distal/proximal arm (O2d/p), respiratory/axial trunk (O3r/a), or distal/proximal leg (O4d/p). Onset symptoms are defined by weakness or slowed, poorly coordinated voluntary movements in the muscles of the head, arm, trunk, or leg, including dysarthria, dysphagia, dysphonia, dyspnea, and axial instability. Propagation (P1(n)) or absence of propagation (P0(n)) of motor symptoms from the onset region to another body region are designated, where n denotes the number of months from onset to propagation or assessment. The degree of UMN dysfunction (slowed, poorly coordinated voluntary movements, hyperreflexia and/or spastic muscle tone, emotional lability) and/or LMN dysfunction (weakness with associated muscle atrophy) is classified as follows: balanced UMN and LMN dysfunction (M0); dominant (M1d) or pure UMN dysfunction (M1p); dominant (M2d) or pure LMN dysfunction (M2p); and dissociated UMN/LMN dysfunction (M3), in which the arms and legs predominantly show LMN and UMN involvement, respectively.

A deep-learning U-Net++-based model was used for segmentation and feature extraction. The frequency and maximum amplitude of tongue movements were quantified. Clinical measures included the ALS Functional Rating Scale-revised (ALSFRS-r) bulbar sub-scores, tongue fasciculations, jaw jerk, and tongue \"spasticity\". Between-group differences and associations between tongue metrics and clinical features were assessed. The U-Net++-based model achieved robust segmentation performance. Patients showed lower tongue movement frequency than controls (0.14 vs. 0.40, t = -9.58, p < 0.001).

Methods: A systematic review was conducted following a pre-registered protocol. Databases were searched for studies involving people living with ALS that addressed timing of assistive technology interventions for communication or technology control. Screening and data extraction were completed in duplicate, findings were synthesized using a thematic analysis, and relevant findings presented as a descriptive summary. Results: Twenty-eight studies met the inclusion criteria. Evidence focused overwhelmingly on communication support rather than wider assistive technology interventions. Need for a communication aid typically occurs between one and five years from diagnosis and the timing of this varies significantly according to the site of onset of ALS. There are significant variations in the timing of changes for individuals within these groupings and there are likely a larger number of groupings that would be clinically useful. A significant correlation between changes in speaking rate and intelligibility has been shown. Once changes to speech do start to occur then the time to the loss of functional speech appears relatively consistent across the types of ALS. Conclusion: Current best practice guidelines are not reflective of the findings of this review and do not support professionals in identifying how to provide timely support. Monitoring speech changes systematically may support timely intervention.

These disorders profoundly affect patient health and quality of life through complex sensorimotor impairments. Objective: The aims was to provide a comprehensive, evidence-based review of the neuroanatomical substrates, pathophysiology, diagnostic approaches, and management strategies for dysphagia and dysarthria in neurodegenerative diseases with emphasis on their multisystem nature and integrated treatment approaches. Methods: A narrative literature review was conducted using PubMed, Scopus, and Web of Science databases (2000-2024), focusing on Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), progressive supranuclear palsy (PSP), and multiple system atrophy (MSA). Search terms included \"dysphagia\", \"dysarthria\", \"neurodegenerative diseases\", \"neural networks\", \"swallowing control\" and \"speech production.\" Studies on neuroanatomy, pathophysiology, diagnostic tools, and therapeutic interventions were included. Results: Contemporary neuroscience demonstrates that swallowing and speech control involve extensive neural networks beyond the brainstem, including bilateral sensorimotor cortex, insula, cingulate gyrus, basal ganglia, and cerebellum. Disease-specific patterns reflect multisystem involvement: PD affects basal ganglia and multiple brainstem nuclei; ALS involves cortical and brainstem motor neurons; MSA causes widespread autonomic and motor degeneration; PSP produces tau-related damage across multiple brain regions. Diagnostic approaches combining fiberoptic endoscopic evaluation, videofluoroscopy, acoustic analysis, and neuroimaging enable precise characterization. Management requires multidisciplinary Integrated teams implementing coordinated speech-swallowing therapy, pharmacological interventions, and assistive technologies. Conclusions: Dysphagia and dysarthria in neurodegenerative diseases result from multifocal brain damage affecting distributed neural networks. Understanding this multisystem pathophysiology enables more effective integrated assessment and treatment approaches, enhancing patient outcomes and quality of life."

Early detection of bulbar symptoms is crucial for timely diagnosis and intervention; however, variability in symptom progression complicates clinical assessment. This retrospective observational study aimed to classify patients with ALS into three groups - spinal onset, spinal onset with bulbar involvement, and bulbar onset - and to identify speech evaluation metrics that effectively differentiate these groups. Data from 68 patients with ALS were retrospectively analyzed. Speech samples were collected and evaluated for alternating motion rate (AMR), maximum phonation time (MPT), nasality, maximum tongue pressure (MTP), speech rate, and speech intelligibility. Group comparisons and receiver operating characteristic (ROC) curve analyses were conducted to assess discriminatory ability. AMR significantly differed among the three groups, with the spinal-onset group demonstrating the highest rates and the bulbar-onset group showing the lowest rates. ROC analysis indicated that AMR exhibited excellent discriminatory power, particularly in distinguishing spinal-from bulbar-onset ALS. Significant differences were also observed in MTP, nasality, speech rate, and speech intelligibility, although some metrics were less effective in differentiating the intermediate group. No significant group differences were found in MPT. These findings suggest that the AMR is a sensitive and easily administered measure for detecting bulbar symptoms and distinguishing ALS subtypes. The intermediate characteristics observed in the spinal-onset with bulbar involvement group support this classification as a distinct clinical phenotype. Combining AMR with secondary measures such as MTP, nasality, speech rate, and speech intelligibility may enhance early detection of bulbar symptoms and improve clinical decision-making."

We conducted a retrospective study including 50 ALS patients evaluated in a phoniatrics consultation with available sustained vowel recordings, demographic data, and functional assessments. Nested logistic regression models were developed to predict clinical outcomes, progressively incorporating demographic variables, functional indices (Grade, Roughness, Breathiness, Asthenia, Strain, and Barthel), acoustic features (fundamental frequency, jitter, shimmer, harmonics-to-noise ratio), and biomechanical voice parameters (Pr1-Pr22). Model performance was assessed using receiver operating characteristic curves and area under the curve (AUC) comparisons via DeLong tests. Stepwise Akaike Information Criterion\u00a0(StepAIC) was applied to optimize the final model. A Cox proportional hazards model was used to evaluate the association between voice parameters and survival time. The final StepAIC model, which included a subset of biomechanical features, achieved excellent predictive performance (AUC\u00a0=\u00a00.903, 95% confidence interval: 0.816-0.989), significantly outperforming baseline and acoustic-only models. Bootstrapping confirmed the model's robustness and generalizability. Cox regression analysis showed that the derived risk scores stratified patients into tertiles with significantly different survival probabilities (log-rank P\u00a0<\u00a00.0001; hazard ratio for high vs. low-risk group\u00a0=\u00a011.2). Biomechanical voice features are strong predictors of mortality in ALS and outperform traditional clinical and acoustic indices. These findings support the integration of voice analysis into ALS monitoring protocols as a non-invasive, cost-effective, and scalable prognostic tool."

As interest in speech analysis grows, distinguishing between conditions becomes critical for reliable diagnosis and assessment. This pilot study explores speech biosignatures in two distinct neurodegenerative conditions: (1) mild traumatic brain injuries (eg, concussions) and (2) Parkinson disease (PD) as the neurodegenerative condition. The study included speech samples from 235 participants (97 concussed and 94 age-matched healthy controls, 29 PD and 15 healthy controls) for the PaTaKa test and 239 participants (91 concussed and 104 healthy controls, 29 PD and 15 healthy controls) for the Sustained Vowel (/ah/) test. Age-matched healthy controls were used. Young age-matched controls were used for concussion and respective age-matched controls for neurodegenerative participants (15 healthy samples for both tests). Data augmentation with noise was applied to balance small datasets for neurodegenerative and healthy controls. Machine learning models (support vector machine, decision tree, random forest, and Extreme Gradient Boosting) were employed using 37 temporal and spectral speech features. A 5-fold stratified cross-validation was used to evaluate classification performance. For the PaTaKa test, classifiers performed well, achieving F 1-scores above 0.9 for concussed versus healthy and concussed versus neurodegenerative classifications across all models. Initial tests using the original dataset for neurodegenerative versus healthy classification yielded very poor results, with F 1-scores below 0.2 and accuracy under 30% (eg, below 12 out of 44 correctly classified samples) across all models. This underscored the need for data augmentation, which significantly improved performance to 60%-70% (eg, 26-31 out of 44 samples) accuracy. In contrast, the Sustained Vowel test showed mixed results; F 1-scores remained high (more than 0.85 across all models) for concussed versus neurodegenerative classifications but were significantly lower for concussed versus healthy (0.59-0.62) and neurodegenerative versus healthy (0.33-0.77), depending on the model. This study highlights the potential of speech features as biomarkers for neurodegenerative conditions. The PaTaKa test exhibited strong discriminative ability, especially for concussed versus neurodegenerative and concussed versus healthy tasks, whereas challenges remain for neurodegenerative versus healthy classification. These findings emphasize the need for further exploration of speech-based tools for differential diagnosis and early identification in neurodegenerative health."

In neurodegenerative diseases affecting the brainstem-such as progressive supranuclear palsy (PSP), amyotrophic lateral sclerosis (ALS), and multiple system atrophy (MSA)-bulbar dysfunction often impairs tongue propulsion and motility, affecting both swallowing (dysphagia) and phonation (dysarthria). This study aimed to investigate whether vowel-based acoustic features are associated with swallowing severity in brainstem-related disorders and to explore their potential as surrogate markers of bulbar involvement. Methods: This was a cross-sectional observational study. Thirty-one patients (13 PSP, 12 ALS, 6 MSA) underwent clinical dysarthria assessment, acoustic analysis of the first (F1) and second (F2) formants during sustained phonation of /a/, /i/, /e/, and /u/, and swallowing evaluation using standardized clinical scales (DOSS, FOIS, ASHA-NOMS) and fiberoptic endoscopic evaluation (Pooling Score, Penetration-Aspiration Scale). The vowel space area (tVSA, qVSA) and Formant Centralization Ratio (FCR) were computed. Results: Significant correlations emerged between acoustic vowel metrics and dysphagia severity, especially for liquids. The FCR showed strong correlations with DOSS (\u03c1 = -0.660, p < 0.0001), FOIS (\u03c1 = -0.531, p = 0.002), ASHA-NOMS (\u03c1 = -0.604, p < 0.0001), and instrumental scores for liquids: the Pooling Score (\u03c1 = 0.538, p = 0.002) and PAS (\u03c1 = 0.630, p < 0.0001). VSA measures were also associated significantly with liquid swallowing impairment. F2u correlated with dysarthria severity and all liquid-related dysphagia scores. Conclusions: Vowel-based acoustic parameters, particularly FCR and F2u, reflect the shared neuromotor substrate of articulation and swallowing. Acoustic analysis may support early detection and monitoring of bulbar dysfunction, especially where instrumental assessments are limited."

A total of 92 individuals were included in this study (21 PSP, 21 PD, 18 HD, 15 ALS, and 16 healthy elderly controls (CTR)). The Rainbow Passage was collected on a digital device and analyzed to extract 12 speech features representing speech production. A set of Elastic Net ML models was trained on these speech features to differentiate between diagnostic classes. A specialized Support Vector Machine ML model was then developed to differentiate PSP from PD. Elastic Net models achieved a balanced accuracy of 77% over 5 diagnostic classes (group-specific sensitivities of 76% for PSP, 67% for PD, 83% for HD, 73% for ALS, and 88% for CTR) and 83% over 4 diagnostic classes (group-specific sensitivities of 83% for PSP-PD, 83% for HD, 73% for ALS, and 94% for CTR).

Quantitative motor speech analysis can identify features of dysarthria that worsen with ALS progression but are not, inherently, clinically meaningful. Listener effort (LE) is a clinician-rated feature describing how much effort the listener needs to exert to understand the dysarthric speaker. This study investigated whether LE could act as a clinically meaningful measure of ALS dysarthria that could be used as an outcome measure in clinical trials. The Everything ALS Speech Study obtained longitudinal clinical information and speech recordings from 292 participants. In a subset of 125 participants, we measured speaking rate and three speech-language pathologists (SLPs) with expertise in ALS rated LE. We also built and tested a LE prediction algorithm to predict the SLPs' rating of LE. In addition, all speech recordings and associated clinical data are now being made available to ALS researchers via the Everything ALS portal. LE intra- and inter-rater reliability was very high (ICC 0.94-0.95). LE correlated with other measures of dysarthria at baseline and changed over time in participants with ALS (slope 0.77 pts/month, SE = 0.15, P < 0.001) but not controls (slope 0.005 pts/month, SE = 0.02, P = 0.807). The slope of LE progression was faster in people with bulbar onset than non-bulbar onset ALS (1.66 points/month versus 0.42 pts/month; P < 0.001) but was similar in all participants who had bulbar dysfunction at baseline, regardless of ALS site of onset (1.52 pts/month for bulbar onset versus 0.98 pts/month for non-bulbar onset with current bulbar involvement; P = 0.36). The LE prediction model predicted the true LE, with an average R 2 of 0.83 \u00b1 0.07. Dysarthria is associated with decreased quality of life in people with ALS. Quantitative measures of dysarthria in ALS could be useful as ALS clinical trial outcome measures, providing insight into the progression of bulbar symptoms. Speaking rate quantifies progression but is variable across speaking stimuli, emotional states and contextual factors. LE is more inherently clinically meaningful, can be measured reliably by SLPs, changes quantitatively over time and is highly reproducible, thus may be useful as a clinical outcome assessment for ALS clinical trials. Furthermore, a LE prediction model is effective at predicting LE scores and should be validated on an external dataset."

A validated objective marker is however lacking to characterize and phenotype bulbar involvement, positing a major barrier to early detection, progress monitoring, and tailored care. This study aimed to bridge this gap by constructing a multiplex functional mandibular muscle network to provide a novel objective measurement tool of bulbar involvement. A noninvasive electrophysiological technique-surface electromyography-was combined with graph network analysis to extract 48 features measuring the regulatory mechanisms, connectivity, integration, segregation, assortativity, and lateralization of the functional muscle network during a speech task. These features were clustered into 10 interpretable latent factors. To evaluate the utility of the muscle network as a bulbar measurement tool, a heterogenous ALS cohort, consisting of eight individuals with overt clinical bulbar symptoms and seven without, along with 10 neurologically healthy controls, was employed to train and validate statistical and machine learning algorithms to assess the disease effects on the network features and the relation of the network performance to the current clinical diagnostic standard and behavioral patterns of bulbar involvement. Significant disease effects were found on most network features. The most robust effects were manifested by reduced and more variable myoelectric activities, and reduced functional connectivity and integration of the muscle network. The 10 latent factors (1) demonstrated acceptably high efficacy for detecting bulbar neuromuscular changes across all clinically confirmed symptomatic cases and clinically silent prodromal cases (area under the curve = 0.89-0.91; F1 score = 0.85-0.87; precision = 0.84-0.86; recall = 0.87-0.88); and (2) selectively correlated with clinically meaningful behavioral patterns (conditional R 2 = 0.45-0.81). The functional muscle network shows promise for an objective quantifiable measurement tool to improve early detection and profiling of bulbar involvement across the prodromal and symptomatic stages. This tool has various strengths, including the use of a clinically readily available noninvasive instrument, fully automated data processing and analytics, and generation of interpretable objective outcome measures (i.e., latent factors), together rendering it highly scalable in routine clinical practice for assessing and monitoring of bulbar involvement."

Standard clinical tools for bulbar assessment focus primarily on clinical symptoms and functional outcomes. However, ALS is known to have a long, clinically silent prodromal stage characterized by complex subclinical changes at various levels of the bulbar motor system. These changes accumulate over time and eventually culminate in clinical symptoms and functional declines. Detection of these subclinical changes is critical, both for mechanistic understanding of bulbar neuromuscular pathology and for optimal clinical management of bulbar dysfunction in ALS. To this end, we developed a novel multimodal measurement tool based on two clinically readily available, noninvasive instruments-facial surface electromyography (sEMG) and acoustic techniques-to hierarchically assess seven constructs of bulbar/speech motor control at the neuromuscular and acoustic levels. These constructs, including prosody, pause, functional connectivity, amplitude, rhythm, complexity, and regularity, are both mechanically and clinically relevant to bulbar involvement. Using a custom-developed, fully automated data analytic algorithm, a variety of features were extracted from the sEMG and acoustic recordings of a speech task performed by 13 individuals with ALS and 10 neurologically healthy controls. These features were then factorized into 10 composite outcome measures using confirmatory factor analysis. Statistical and machine learning techniques were applied to these composite outcome measures to evaluate their reliability (internal consistency), validity (concurrent and construct), and efficacy for early detection and progress monitoring of bulbar involvement in ALS. The composite outcome measures were demonstrated to (1) be internally consistent and structurally valid in measuring the targeted constructs; (2) hold concurrent validity with the existing clinical and functional criteria for bulbar assessment; and (3) outperform the outcome measures obtained from each constituent modality in differentiating individuals with ALS from healthy controls. Moreover, the composite outcome measures combined demonstrated high efficacy for detecting subclinical changes in the targeted constructs, both during the prodromal stage and during the transition from prodromal to symptomatic stages. The findings provided compelling initial evidence for the utility of the multimodal measurement tool for improving early detection and progress monitoring of bulbar involvement in ALS, which have important implications in facilitating timely access to and delivery of optimal clinical care of bulbar dysfunction."

Automated acoustic assessment of speech in ALS is attractive, and there is a pressing need to validate such tools in line with best practices, including analytical and clinical validation. We hypothesized that data analysis using a novel speech assessment pipeline would correspond strongly to analyses performed using lab-standard practices and that acoustic features from the novel pipeline would correspond to clinical outcomes of interest in ALS. We analyzed data from three standard speech assessment tasks (i.e., vowel phonation, passage reading, and diadochokinesis) in 122 ALS patients. Data were analyzed automatically using a pipeline developed by Winterlight Labs, which yielded 53 acoustic features. First, for analytical validation, data were analyzed using a lab-standard analysis pipeline for comparison. This was followed by univariate analysis (Spearman correlations between individual features in Winterlight and in-lab datasets) and multivariate analysis (sparse canonical correlation analysis (SCCA)). Subsequently, clinical validation was performed. This included univariate analysis (Spearman correlation between automated acoustic features and clinical measures) and multivariate analysis (interpretable autoencoder-based dimensionality reduction). Analytical validity was demonstrated by substantial univariate correlations (Spearman's \u03c1\u2009>\u20090.70) between corresponding pairs of features from automated and lab-based datasets, as well as interpretable SCCA feature groups.

AMR and SMR were significantly lower in patients with bulbar onset than those with spinal onset, both with and without bulbar symptoms. Furthermore, these values were also lower in patients with spinal onset associated with bulbar symptoms than in those with spinal onset alone.

Methods: Using their speech recordings, we measured articulatory precision (a measure of the crispness of pronunciation) using an algorithm that analyzed the acoustic signal of each phoneme in the words produced. First, we established the analytical and clinical validity of the measure of articulatory precision, showing that the measure correlated with perceptual ratings of articulatory precision (r = .9). Second, using articulatory precision from speech samples from each participant collected over a 45-90\u2009day model calibration period, we showed it was possible to predict articulatory precision 30-90 days after the last day of the model calibration period. Finally, we showed that the predicted articulatory precision scores mapped onto ALSFRS-R speech subscores. Results: the mean absolute error was as low as 4% for articulatory precision and 14% for ALSFRS-R speech subscores relative to the total range of their respective scales.

It refers to motor neuron disability in the corticobulbar area of the brainstem which leads to a dysfunction of speech and swallowing. One of the earliest symptoms of bulbar dysfunction is voice deterioration characterized by grossly defective articulation, extremely slow laborious speech, marked hypernasality and severe harshness. Recently, research efforts have focused on voice analysis to capture this dysfunction. The main aim of this paper is to provide a new methodology to diagnose this dysfunction automatically at early stages of the disease, earlier than clinicians can do. The study focused on the creation of a voiceprint consisting of a pattern generated from the quasi-periodic components of a steady portion of the five Spanish vowels and the computation of the five principal and independent components of this pattern. Then, a set of statistically significant features was obtained using multivariate analysis of variance and the outcomes of the most common supervised classification models were obtained. The best model (random forest) obtained an accuracy, sensitivity and specificity of 88.3%, 85.0% and 95.0% respectively when classifying bulbar vs. control participants but the results worsened when classifying bulbar vs. no-bulbar patients (accuracy, sensitivity and specificity of 78.7%, 80.0% and 77.5% respectively for support vector machines). Due to the great uncertainty found in the annotated corpus of the ALS patients without bulbar involvement, we used a safe semi-supervised support vector machine to relabel the ALS participants diagnosed without bulbar involvement as bulbar and no-bulbar. The performance of the results obtained increased, especially when classifying bulbar and no-bulbar patients obtaining an accuracy, sensitivity and specificity of 91.0%, 83.3% and 100.0% respectively for support vector machines. This demonstrates that our model can improve the diagnosis of bulbar dysfunction compared not only with clinicians, but also the methods published to date. The results obtained demonstrate the efficiency and applicability of the methodology presented in this paper. It may lead to the development of a cheap and easy-to-use tool to identify this dysfunction in early stages of the disease and monitor progress."

Speech intelligibility is a crucial component of communication affected in ALS, requiring objective, scalable assessment methods as an indicator of disease progression and treatment efficacy. Objective: This study investigates whether speech and bulbar function in ALS could be evaluated and monitored utilizing an automated digital measure of speech intelligibility derived from naturalistic picture descriptions. Methods: Speech recordings from 44 patients living with ALS (plwALS) and 49 matched healthy controls (HC) were analyzed and processed utilizing an automated speech analysis pipeline to extract an intelligibility score. These were part of a cross-sectional and longitudinal study involving two assessments.\u00a0Results: The findings confirmed that speech intelligibility is significantly reduced in plwALS compared to HC. Those with bulbar-onset ALS have lower intelligibility than those with spinal-onset ALS, and the intelligibility of individuals with bulbar symptoms-regardless of the onset type-is lower than in plwALS without bulbar symptoms. Declining ALS-related speech scores correspond with worsening intelligibility in longitudinal assessments. Intelligibility correlates strongly with bulbar-specific clinical measures but not with global scores, highlighting its role in tracking bulbar progression. In some plwALS, we were able to demonstrate that automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring. Conclusion: Our findings highlight that automated speech intelligibility assessments can be a valuable marker to improve clinical monitoring and facilitate earlier intervention in ALS as a supplement to standard assessments."

These changes\u2014often subtle and requiring sophisticated extraction\u2014precede functional communicative decline and may provide a window for early diagnosis.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe clinical trajectory of Amyotrophic Lateral Sclerosis (ALS) is increasingly recognized to include a prolonged, clinically silent prodromal period. Quantitative analysis of vocal and speech motor control, utilizing surface electromyography (sEMG) and acoustic signal processing, identifies nuanced physiological patterns of decline\u2014specifically in phonatory stability, glottal tension, and articulatory precision\u2014that emerge before the manifestation of traditional clinical symptoms, offering a non-invasive, scalable biomarker for early detection.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic Lateral Sclerosis is traditionally viewed as a disorder of motor neuron degeneration characterized by progressive limb or bulbar weakness. However, emerging research into digital speech biomarkers indicates that bulbar involvement can be detected through non-invasive assessments during the prodromal phase. Current clinical standards, such as the ALS Functional Rating Scale-Revised (ALSFRS-R), lack the sensitivity to capture these subclinical neuromuscular changes. Digital voice analysis\u2014leveraging high-frequency acoustic data and biomechanical models of vocal fold vibration\u2014serves as a high-fidelity diagnostic instrument. The integration of artificial intelligence and machine learning pipelines allows for the automatic extraction of composite outcome measures that demonstrate clinical validity in differentiating ALS profiles from healthy aging and other neurodegenerative conditions. These metrics, such as articulatory rate, fundamental frequency variation, and glottal stability, act as objective markers of the underlying motor neuron pathology, potentially enabling earlier intervention and precision-based therapeutic monitoring.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Subclinical Detection:** Artificial intelligence frameworks can identify neuromuscular changes during the \"clinically silent prodromal stage\" before functional decline is apparent.\n*   **Biomechanical Precision:** Biomechanical voice parameters reflecting glottal tension and vocal fold stability are sensitive enough to differentiate clinical phenotypes (bulbar vs. spinal onset).\n*   **Multimodal Integration:** Combining facial sEMG and acoustic signals outperforms single-modality assessments in detecting early bulbar motor dysfunction.\n*   **Listener Effort (LE):** LE is a clinician-rated metric that captures meaningful change in dysarthria and shows potential as a responsive clinical trial endpoint.\n*   **Smartphone Utility:** Simple, smartphone-based assessment tasks (e.g., tongue lateralization or vowel phonation) correlate highly with laboratory-standard assessments, increasing access.\n*   **Stability of Biomarkers:** Despite disease progression, high-gamma cortical features in ECoG speech BCIs show long-term stability, suggesting durability for assistive interfaces.\n*   **Predictive Modeling:** Subject-specific prognostic models can now predict articulatory precision and ALSFRS-R speech subscores 30\u201390 days in advance.\n*   **Vocal Subtypes:** Unsupervised clustering reveals \"vocal profiles\" that transcend traditional diagnostic labels, indicating that voice features capture functional patterns of voice production across different disorders.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

We evaluated the feasibility of a multimodal home monitoring protocol in ALS. Methods: We conducted a 3-month prospective cohort study at the University Medical Center Utrecht, Netherlands, with monthly home assessments of spirometry, accelerometry, speech, and questionnaires on functioning. The primary outcome was protocol adherence, defined as percentage of completed assessments. Secondary outcomes included acceptability ((totally) agree, neutral, (totally) disagree), and perceived burden, ranging from 0 (no burden) to 10 (extremely burdensome). Exploratory analyses were performed to evaluate changes in digital endpoints using linear mixed-effects models. Findings: Fifty patients with ALS were included (January 2023 - June 2025), of whom 47 (94%) completed the 3-month follow-up. Overall adherence was 83.2% (95% CI 76.9-88.6) and did not differ across modalities (p\u2009=\u20090.75). Adherers did not differ from non-adherers in either demographic or disease characteristics. In month 3, 93.0% to 95.3% of patients considered monthly remote assessments as acceptable, with a mean burden score of 2.0 (95% CI 1.7 to 2.3); burden was highest for speech (2.5) and the lowest for questionnaires (1.5). Digital endpoints showed significant change over 3\u2009months (all p\u2009<\u20090.05). Interpretation: This study demonstrates good adherence and acceptability of a multimodal remote monitoring protocol. Digital endpoints offer an innovative approach to capturing disease progression.

Recent reductions in global health funding have threatened TB control, making comprehensive assessment of TB, HIV-related TB, and drug-resistant TB burdens before these disruptions essential for shaping effective responses. The WHO End TB Strategy sets targets of a 95% reduction in TB deaths and a 90% reduction in TB incidence between 2015 and 2035. Using results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023, this study aims to assess the burden of TB and multidrug-resistant TB (MDR-TB) across 204 countries and territories, and to evaluate progress towards the WHO End TB incidence and mortality targets. We quantified TB mortality using the Cause of Death Ensemble modelling platform with global vital registration, surveillance, verbal autopsy, and minimally invasive tissue sampling data. For TB morbidity estimation, we simultaneously modelled incidence, prevalence, and mortality by age and sex using DisMod-MR 2.1. A population attributable fraction (PAF) approach was applied to stratify morbidity and mortality estimates by HIV and drug-resistance status. We also calculated disability-adjusted life-years (DALYs) as the sum of years of life lost and years lived with disability. For the risk factor analysis, a comparative risk assessment framework was used and PAFs were derived for alcohol use, smoking, and high fasting plasma glucose to determine the proportion of TB burden associated with these risk factors. In 2023, there were an estimated 9\u00b711 million (95% uncertainty interval 8\u00b704-10\u00b73) incident cases of all-form TB, 1\u00b722 million (0\u00b798-1\u00b749) deaths, and 54\u00b76 million (43\u00b78-65\u00b75) DALYs globally. HIV-related TB comprised 781\u2008000 (690\u2008000-879\u2008000) incident cases and 210\u2008000 (142\u2008000-279\u2008000) deaths, contributing 11\u00b70 million (7\u00b756-14\u00b73) DALYs. MDR-TB accounted for 466\u2008000 (198\u2008000-1\u2008080\u2008000) incident cases, 102\u2008000 (31\u2008700-238\u2008000) deaths, and 3\u00b796 million (1\u00b731-9\u00b701) DALYs. From 2015 to 2023, global all-form TB incidence rates declined by 19\u00b72% (17\u00b78-20\u00b75) and deaths declined by 22\u00b76% (4\u00b77-35\u00b77); declines were larger for drug-susceptible TB than for MDR-TB. Sub-Saharan Africa and south Asia had the highest mortality burdens in 2023; reductions in all-form TB incidence and mortality were uneven between 2000 and 2023, with limited progress in both measures in Latin America and the Caribbean. Removing smoking, alcohol use, and high fasting plasma glucose would reduce global TB deaths to 768\u2008000 (592\u2008000-970\u2008000) and DALYs to 34\u00b79 million (27\u00b78-43\u00b78) in 2023; MDR-TB deaths would decrease to 77\u2008200 (23\u2008400-183\u2008000) and DALYs to 3\u00b712 million (1\u00b703-7\u00b729). Global progress towards WHO End TB targets is disparate and fragile. Although many regions achieved meaningful gains, others have stagnated in recent years. The complexity of TB prevention is amplified by divergent MDR-TB trends, the persistent burden of HIV, and growing exposure to modifiable risk factors. Recent volatility in global health financing threatens to further destabilise this vulnerable epidemiological landscape; concerted action is urgently needed to temper disruptions and preserve progress.

This study aimed to investigate the relationship between clinical dysphagia assessment tools (EAT-10, GUSS, RSST, and sialorrhea severity) and videofluoroscopic swallowing study (VFSS) findings in patients with ALS. Materials and Methods: This retrospective observational study included 60 patients with ALS classified as spinal-onset (n = 38) or bulbar-onset (n = 22). Relationships between clinical assessments and VFSS findings were analysed using Spearman correlation analysis. Exploratory multivariable regression and receiver operating characteristic (ROC) analyses were performed to evaluate associations and aspiration risk discrimination. Results: Strong negative correlations were observed between PAS-Liquid and RSST and GUSS scores, whereas EAT-10 showed a strong positive correlation (all p < 0.001). ROC analyses demonstrated good discriminative ability for aspiration risk for GUSS (AUC = 0.89), RSST (AUC = 0.88), and EAT-10 (AUC = 0.82). Patients with bulbar-onset ALS demonstrated higher penetration-aspiration severity and lower functional oral intake. Conclusions: Clinical dysphagia assessment tools showed significant associations with instrumental swallowing findings in ALS. GUSS and RSST demonstrated good discriminative ability for aspiration risk and may be clinically useful bedside screening tools. However, instrumental swallowing assessment remains essential whenever feasible.\n\nID: 42333954\nTitle: Thinning of the oral motor cortex is linked to impaired speech in amyotrophic lateral sclerosis.\nAbstract: Most individuals with amyotrophic lateral sclerosis (ALS) develop bulbar impairment as their disease progresses. The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech\u2011derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1\u2011weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS.\n\nID: 42297978\nTitle: Long-term independent use of an intracortical brain-computer interface for speech and cursor control.\nAbstract: Brain-computer interfaces (BCIs) can provide naturalistic communication and digital access to people with severe paralysis by decoding neural activity associated with attempted speech and movement. Recent work has demonstrated highly accurate intracortical BCIs for speech and cursor control, but two critical capabilities needed for practical viability were unmet: independent at-home operation without researcher assistance and reliable long-term performance supporting accurate speech and cursor decoding. Here we demonstrate the independent and near-daily use of a multimodal BCI with novel brain-to-text speech and computer cursor decoders by a man with paralysis and severe dysarthria due to amyotrophic lateral sclerosis. Over nearly 2\u2009years, the participant used the BCI for more than 3,800\u2009h at home with no researchers present to maintain rich interpersonal communication with his family and friends, independently control his personal computer and sustain full-time employment-despite being paralyzed. He communicated 183,060 sentences-totaling 1,960,163 words-at an average rate of 56 words per minute. He labeled 92% of sentences as being decoded at least mostly correctly. In formal quantifications of performance where he was asked to say words presented on a screen, attempted speech was consistently decoded with more than 99% word accuracy (125,000 word vocabulary). The participant also used the speech BCI as keyboard input and the cursor BCI as mouse input to control his personal computer, enabling him to send text messages and emails and to browse the internet. These results demonstrate that intracortical BCIs have the potential to support independent use in the home, marking a critical step toward practical assistive technology for people with severe motor impairment.\n\nID: 42241188\nTitle: The Unfinished Breath: Caregiver Perceptions of Terminal Events and Gaps in Amyotrophic Lateral Sclerosis Care in India.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder with a high symptom burden and limited survival. Little is known about the terminal phase experiences, symptom prevalence, and end-of-life care patterns of people with ALS (PALS) in India. This study aimed to assess terminal events and caregiver-reported outcomes in PALS to identify gaps in ALS care delivery in India. A cross-sectional telephonic survey was conducted among bereaved caregivers of PALS enrolled in the Neuropalliative and Supportive Care project between December 2021 and May 2024. A structured, validated questionnaire was used to collect data on demographics, terminal-phase symptoms, medical interventions, and the nature of death as perceived by primary caregivers. Descriptive statistics and appropriate statistical analyses were performed. A total of 130 caregivers participated in the survey; the majority (57.7%) were sons or daughters. Among the 130 PALS, 76 (58.5%) were men; 56.2% had limb onset and 43.8% had bulbar onset. The mean age at death was 53.5 \u00b1 11.4 years. Most patients (57.7%) died at home, and 29.2% experienced sudden death. Patients who died in the hospital were more likely to be on invasive mechanical ventilation ( P < 0.001). The most common terminal symptoms were breathlessness (79.2%), excessive oral secretions (54.6%), followed by anxiety or restlessness (44.6%). Only 20% received bilevel positive airway pressure, and 25.4% were on percutaneous endoscopic gastrostomy. A significant association was found between bulbar onset and assisted feeding ( P = 0.002). This study highlights the need for proactive, community-integrated palliative care services and emphasizes the urgency of early intervention and caregiver support to improve end-of-life experiences in PALS in India.\n\nID: 42191539\nTitle: Discovering Hidden Vocal Subtypes: An Unsupervised Acoustic-Biomechanical Exploration of Voice Profiles.\nAbstract: This study aims to explore latent acoustic-biomechanical patterns of voice production using an unsupervised multivariate approach, and to identify data-driven vocal profiles across individuals with amyotrophic lateral sclerosis (ALS) and nonneurological\u00a0dysphonia. A cross-sectional sample of 100 individuals, including patients with ALS\u00a0and individuals with nonneurological dysphonia, was analyzed. Sustained vowel phonation was recorded and characterized using 26 variables, including standard acoustic measures (fundamental frequency -fo-, jitter, shimmer, and harmonics-to-noise ratio (HNR)) and 22 biomechanical parameters. Principal component analysis\u00a0was applied to investigate relationships among variables and reduce dimensionality. Unsupervised clustering was performed at both the variable level to identify functional groupings and the participant level to derive data-driven voice profiles. Cluster validity was assessed using internal indices. Post hoc statistical comparisons and chi-square tests were used descriptively to characterize between-cluster differences and their relationship with clinical categories. The first five principal components explained 70.7% of the total variance, revealing structured relationships between acoustic and biomechanical features. Participant level clustering consistently supported a two-profile solution. Fifteen voice parameters differed significantly between profiles after false discovery rate correction, with the largest effects observed for shimmer, HNR, and the biomechanical parameter Pr11, reflecting differences in vocal stability and noise-related characteristics. The identified profiles were not significantly associated with clinical diagnostic categories. An unsupervised multimodal analysis of sustained phonation revealed two coherent vocal profiles that transcend traditional diagnostic labels. These data-driven voice phenotypes may capture functional patterns of voice production and support future efforts toward more refined and personalized characterization of voice disorders.\n\nID: 42166520\nTitle: Clinical characterization and natural history of ALS8/VAPB p.Pro56Ser: upper motor neurone signs, survival, and functional milestones in 78 patients.\nAbstract: Amyotrophic lateral sclerosis type 8 (ALS8), caused by the VAPB p.Pro56Ser mutation, is a rare familial motor neurone disease with an incompletely characterized profile. We aimed to characterize the clinical phenotype, upper motor neurone (UMN) sign prevalence, survival, and functional milestones. We retrospectively analyzed 78 patients with ALS8 confirmed via molecular testing or familial linkage analysis from 57 apparently unrelated families. UMN signs were assessed using a five-item composite of pyramidal signs. Survival and milestones were estimated using Kaplan-Meier analysis. Median age at onset was 44.9\u2009years; 51% were men. Onset was lumbar in 94%, proximally predominant. UMN signs were present in 53 patients; none exhibited clonus. At admission, 51% had spinal-onset ALS, 42% progressive muscular atrophy (PMA) and 6% flail leg; 30% of patients with PMA subsequently developed UMN signs. Survival was 21.9\u2009years; times to wheelchair dependence and noninvasive ventilation were 7.0 and 10.0\u2009years, respectively. Bulbar involvement occurred in 17 (21.8%) patients, predominantly as dysphonia. UMN status did not affect survival (p\u2009=\u20090.312). The standardized mortality ratio was 4.54 (95% CI 2.77-7.01), supporting disease-related excess mortality. ALS8 is a slowly progressive motor neurone disease with lumbar onset, ascending progression, and frequent but subtle UMN signs. Survival was markedly prolonged but functional decline followed a predictable sequence. These findings expand the phenotypic characterization of ALS8 and support genetic counseling and anticipatory management.\n\nID: 42151746\nTitle: Perceptions of Speech-Language Pathology Care in Amyotrophic Lateral Sclerosis: A Patient-Centered Exploratory Study.\nAbstract: Given limited research on patient perspectives of speech-language pathology (SLP) services in ALS care, this study aimed to assess the satisfaction with, and understanding of, SLP services by people with ALS (pwALS) and to examine the alignment between services received and patient-reported impairments. A cross-sectional survey assessing pwALS' perceptions of SLPs was distributed from October 2024 to January 2025 through electronic mailing lists of relevant professional organizations. A questionnaire examined pwALS' understanding of the SLP role, satisfaction levels, alignment between patient-reported impairments and SLP interventions, and perceived gaps in care. Responses were analyzed using descriptive statistics, with open-ended items analyzed using qualitative analysis. The 81 survey respondents consisted of pwALS (81.5%), caregivers (11.1%), family members (4.9%), and others (2.5%). Overall satisfaction with SLP care was high, though open-ended responses revealed gaps in understanding. Many were unaware of the full scope of SLP services; only 17.3% recognized cognitive evaluation and 8.6% cognitive therapy, compared with speech (77.8%) and swallowing (81.5%) evaluations. Reported services often did not align with communication and swallowing needs, but patients educated about a service were significantly more likely to use it. Overall satisfaction with SLP care was high; however, open-ended responses revealed gaps in understanding, unmet needs, and limited awareness of the full scope of SLP services. This misalignment highlights the need for improved patient and caregiver education regarding the role and timing of SLP involvement to enhance engagement, appropriate service use, and outcomes in ALS care.\n\nID: 42137113\nTitle: An interpretable, clinically grounded framework for digital speech biomarker development in neurodegenerative diseases.\nAbstract: Communication ability-a key determinant of quality of life-is frequently affected and progressively declines in neurodegenerative diseases. Effective management of progressive communication disorders requires a personalized approach to deliver timely interventions tailored to the evolving profiles of communicative impairment, thereby supporting functional communication throughout the disease course. To this end, reliable tools capable of detecting and quantifying both disease-specific patterns of communicative impairment and within-disease phenotypic variability are urgently needed. This study leverages Artificial Intelligence and advanced data analytics to develop an acoustic-based framework for automated extraction of interpretable, clinically grounded speech markers to enable objective assessment and phenotyping of progressive communication disorders. Three groups of participants, including 14 individuals with amyotrophic lateral sclerosis (ALS) and 15 individuals with Parkinson's disease (PD), alongside 10 neurologically healthy controls, performed a standardized oral passage reading task, yielding 739 speech samples. Fifty acoustic features were extracted using an automated analytic pipeline and subsequently clustered into six interpretable composite markers. The clinical utility of these markers was evaluated with the recorded speech samples by examining their (1) associations with standardized metrics of cognitive, motor speech, and overall communicative functions, (2) efficacy for detecting and differentiating disease-specific communicative impairment patterns in ALS and PD using supervised machine learning, and (3) utility for within-disease phenotyping and stratification using unsupervised clustering analysis. The markers effectively (1) detected subtle subclinical changes across multiple domains prior to substantial declines in functional communication outcomes; (2) differentiated disease-specific patterns of communicative impairment (multiclass area under the curve > 0.90); and (3) identified subgroups with distinct speech profiles within each disease. The findings support the potential of the proposed framework as a clinically translatable, objective tool to facilitate early detection, differential diagnosis, and phenotyping of progressive communication disorders, ultimately advancing personalized, measurement-based care in neurodegenerative diseases.\n\nID: 42113599\nTitle: Amyotrophic Lateral Sclerosis: A Review.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive weakness due to degeneration of upper motor neurons in the brain and lower motor neurons in the brainstem and spinal cord. It affects approximately 25\u202f000 individuals in the United States. Amyotrophic lateral sclerosis is characterized by progressive painless muscle weakness that typically begins in a focal region of the body, such as limb muscle weakness causing hand weakness or foot drop (65%), cranial muscle weakness causing speech or swallowing problems (20%-25%), or axial muscle weakness causing bent posture (5%-10%), and spreads to other body regions over time. The disease usually manifests with dysfunction indicative of both upper motor neurons (causing muscle stiffness and spasticity) and lower motor neurons (causing weakness, fasciculations, atrophy, and flaccidity). After onset, weakness spreads through the musculature and typically causes death due to respiratory muscle weakness. Among people with ALS, approximately 85% have sporadic ALS, which is not associated with known environmental or genetic factors, and 15% have familial ALS. Amyotrophic lateral sclerosis is diagnosed based on clinical features, which can be supported by results of electromyography. More than 60 genes have been associated with ALS, and most are autosomal dominant. Pathogenic variants in chromosome 9 open reading frame 72 (C9orf72) are found in 40% of all familial ALS cases, and pathogenic variants in superoxide dismutase 1 (SOD1) are found in 20% of patients with familial ALS. Patients with ALS survive a mean of 3 to 5 years after diagnosis, and there are currently no curative therapies. Clinical care primarily focuses on symptom management and quality of life. Three US Food and Drug Administration (FDA)-approved disease-modifying therapies are available in the United States. Riluzole and edaravone are oral medications that slow ALS progression by up to 2 to 4 months, and tofersen is an intrathecally administered gene therapy for patients with SOD1 gene variants. Specialized multidisciplinary teams, comprising neurologists, nurses, therapists, dietitians, and social workers, are associated with improved survival (4-7 months) and quality of life. Amyotrophic lateral sclerosis is a progressive and fatal neurodegenerative disorder of upper and lower motor neurons. No curative therapies exist. Two oral medications, riluzole and edaravone, are approved by the FDA and modestly decrease disease progression in sporadic ALS. Tofersen, an intrathecally administered gene-based therapy, is also FDA approved and slows disease progression in patients with SOD1 pathogenic gene variants.\n\nID: 42051912\nTitle: Amyotrophic lateral sclerosis and chronic inflammatory demyelinating polyneuropathy coexistence in a patient with a C9orf72 variant: case report.\nAbstract: The C9orf72 variation has been strongly implicated in the inheritance of familial ALS, frontotemporal dementia (FTD), and combined ALS-FTD cases. Increasing evidence implicates immune changes and inflammation in some ALS patients. Several studies demonstrated that ALS coexists with CIDP or polyneuropathy. Mouse models of C9orf72 loss-of-function mutations exhibit fatal immune dysregulation. A 62-year-old Caucasian man developed right foot drop, and he underwent fibular nerve release without significant improvement. At the same time, he developed progressive weakness and numbness in his bilateral hands. MRI revealed cervical canal stenosis and neuroforaminal narrowing that prompted neurosurgical decompression without clinical improvement. Subsequently, he developed left foot drop. At the clinic presentation, he exhibited dysarthria, tongue fasciculations, weakness in all extremities, muscle atrophy, widespread fasciculations, and upper extremity hyperreflexia, meeting clinical criteria for ALS. Genetic testing identified a pathogenic variant in the C9orf72 gene, confirming a C9orf72 variant, commonly linked to familial ALS. Brain MRI demonstrated the motor band sign. Although EMG/NCS findings were consistent with lower motor neuron disease, he also had signs of demyelinating polyneuropathy based on conduction parameters. Neuromuscular ultrasound showed significant multifocal nerve enlargement typical of immune-mediated neuropathy. CSF studies revealed albuminocytologic dissociation (protein: 112\u202fmg/dL, with normal cell count) and high albumin quotient and index. He fulfilled the 2021 EAN/PNS criteria for possible typical CIDP. He was treated with intravenous immunoglobulin in addition to riluzole with temporary improvement. This is the first case of the co-existence of CIDP and ALS in the setting of a pathogenic C9orf72 variant.\n\nID: 42040341\nTitle: Translation of surface electromyography into a clinically applicable objective bulbar assessment tool to improve measurement-based care in amyotrophic laterals sclerosis.\nAbstract: This study aims to translate surface electromyography (sEMG) into a clinically applicable, objective tool for assessing bulbar involvement in amyotrophic lateral sclerosis (ALS). A clinically grounded sEMG framework was developed, integrating a standardized, repeatable protocol with a novel analytic pipeline, to automatically extract 60 features from six craniofacial muscle groups during a set of motorically demanding but cognitively and linguistically less challenging oral diadochokinetic (DDK) tasks. Using this framework, 104 oral DDK recordings were acquired from 16 individuals with ALS-nine with overt bulbar symptoms (ALS+B) and seven without (ALS-B)-and 10 healthy controls (HCs). The sEMG features were clustered into 10 interpretable composite measures and validated by evaluating their (1) internal consistency using Cronbach's \u03b1 ; (2) associations with standardized functional outcomes and a biomechanical metric-stiffness-via mediation analysis; (3) discriminatory efficacy in distinguishing ALS+B and ALS-B from HC, as well as from each other, using machine learning classifications; and (4) robustness to common nonmotor confounders, including age, sex, and cognitive-linguistic impairments, through a comparison of discriminatory performance before and after adjustment for these factors. All composite measures exhibited (1) high internal consistency (Cronbach's \u03b1 = 0.89 \u00b1 0.071 ), (2) significant (or marginally significant) direct or stiffness-mediated indirect associations with the functional outcomes, and (3) consistently high discriminatory accuracy (0.82-0.85), both before and after adjustment for confounders. The sEMG framework demonstrates strong potential as a reliable, valid, and robust objective tool to detect subclinical neuromuscular changes throughout the prodromal and symptomatic phases of bulbar involvement in ALS, while remaining resistant against disease-related cognitive-linguistic impairments and disease-unrelated confounders. This tool may augment standard clinical evaluations, enabling earlier detection of bulbar involvement and measurement-based care in ALS.\n\nID: 42011674\nTitle: Speech and swallow outcome measures for ALS and perspectives on remote monitoring: an international survey of speech & language therapists.\nAbstract: Dysarthria and dysphagia occur frequently in Amyotrophic Lateral Sclerosis (ALS). To manage these symptoms, speech & language therapists (SLTs) must identify relevant speech and swallow outcomes and select suitable outcome measurement instruments. Remote monitoring is an evolving mode of health status tracking. This survey aimed to establish SLT perspectives on ALS assessment regarding 1) the clinical meaningfulness of existing outcome measurement instruments 2) remote monitoring 3) usefulness of assessment devices for patient care and 4) bulbar function outcomes and measurement instruments useful for research studies. An online English-language survey was distributed internationally through gatekeepers and social media. Sixty-six SLTs responded from 13 countries. Current outcome measurement instruments were regarded as clinically meaningful in ALS by 35% for speech and 41% for swallow. Only 12% had access to remote monitoring, but 77% would like to avail of it, with 58% perceiving its potential to enhance care. Eighty-two percent deemed remote monitoring using digital patient-reported outcome measures (PROMs) useful. Speech intelligibility measurement was selected as the most useful communication outcome for remote monitoring (92%) and research (94%). SLTs agreed that speech intelligibility test software (72%), smart device apps (70%) and tongue pressure measurement devices (54%) are useful assessment equipment. SLTs want better measurement instruments for speech and swallow in ALS. They regarded technologies including remote monitoring incorporating digital PROMs as useful. Outcomes reflecting communication and swallow functional success level were deemed most useful. These survey findings can inform the selection of digital speech and swallow outcomes for ALS.\n\nID: 41928799\nTitle: Stable speech BCI performance during slow progression of ALS: A longitudinal ECoG study.\nAbstract: Electrocorticographic (ECoG) speech brain-computer interfaces (BCIs) show promise for restoring communication in amyotrophic lateral sclerosis (ALS), but the long-term stability of speech-related neural signals and decoding performance during disease progression remains unclear. We tracked signal characteristics and decoding over 25 months in a participant with ALS to determine how high-gamma (HG, 70-170 Hz) activity changes over time and whether these changes affect offline speech decoding. We implanted two 8\u00d78 subdural ECoG grids over left sensorimotor cortex (SMC) in a participant with slowly progressive bulbar variant ALS. Across 25 months, the participant performed an overt syllable-repetition task (12 consonant-vowel tokens) during simultaneous ECoG and audio recording. We quantified HG activation ratio (ActR), spectral signal-to-noise ratio (SNR; HG/HF, where HF = 300-499 Hz), and peak z-scored HG responses. Speech acoustics were evaluated using first/second formants (F1/F2) and the triangular vowel space area (tVSA). Offline EEGNet-based decoders were assessed in two stages: models trained on post-implant months 1-6 were tested on months 7-25, while models trained on stabilized data (months 7-11) were tested on the remaining period (months 12-25). Electrode-level saliency assessed spatial contributions to decoding. Acoustic analyses showed a significant reduction in tVSA over two years (-44.6 Hz2/day; P < 10-7), consistent with mild intelligibility decline. Neural metrics (ActR and SNR) followed a biphasic trajectory: increasing during the first 6 months, after which ActR stabilized (0.041%/day; P = 0.13), and SNR declined gradually (-0.46%/day, P < 10- 4). The model trained on months 1-6 achieved 55.7% accuracy (chance: 8.33%), but performance declined over time (-0.019%/day; P = 2.1\u00d710-4). Conversely, the model trained on months 7-11 achieved higher accuracy (65.9%) on subsequent data with no significant temporal decline (P = 0.23). Speech-related HG features exhibited an initial unstable period followed by a long-term gradual SNR reduction, potentially reflecting disease progression. Models trained after signal stabilization generalized robustly to data recorded over a year later. These findings confirm that despite reduced absolute HG power and mild acoustic degradation of speech, cortical features remain stable enough to support durable ECoG speech BCIs without frequent recalibration. These findings will motivate future adaptive calibration algorithms that account for slow signal changes while leveraging stable spatial representations in ventral SMC.

These advances have been demonstrated in individuals who are still able to vocalize and move speech articulators. Here, we decoded intended speech from an individual with long-standing anarthria, locked-in syndrome, and ventilator dependence due to advanced symptoms of ALS. We found that phonemes, words, and higher order language units could be decoded well above chance. While sentence decoding accuracy was below that of demonstrations in participants with dysarthria, we attained an extensive characterization of neural signals underlying speech in a person with locked-in syndrome and identify directions for future improvement. These include closed-loop speech imagery training and decoding linguistic (rather than phonemic) units from neural signals in middle precentral gyrus to augment decoding at the sentence level. These results demonstrate that usable speech decoding from motor cortex may be feasible in people with anarthria and ventilator dependence.\n\nID: 41918982\nTitle: Translating AI research into reality: summary of the 2025 voice AI Symposium and Hackathon.\nAbstract: The 2025 Voice AI Symposium represented a transition from conceptual research to clinical implementation in vocal biomarker science. Hosted by the NIH-funded Bridge2AI-Voice consortium, the meeting convened global experts to address the methodological, ethical, and translational challenges of integrating voice-based artificial intelligence (AI) into healthcare. This mini-review synthesizes symposium insights across six domains: multimodal integration, FAIR (Findable, Accessible, Interoperable, Reusable) and CARE (Collective Benefit, Authority to Control, Responsibility, Ethics) data governance, clinical translation, interdisciplinary training, and cross-sector innovation. Research presented demonstrated voice as a latent, multimodal biomarker reflecting neurological, cardiopulmonary, and psychological states, while discussions emphasized ethical data practices and human-centered design. The implementation-focused panels underscored the importance of workflow alignment and usability for adoption in real-world care. Collectively, the symposium reflects a field advancing toward translational readiness and ethical accountability, positioning voice AI as a scalable, inclusive tool for next-generation healthcare.\n\nID: 41907197\nTitle: Hereditary transthyretin amyloidosis mimicking ALS: First genetically proven case report from Saudi Arabia.\nAbstract: Hereditary transthyretin amyloidosis (ATTRv) is a systemic disorder that may mimic motor neuron disease (MND), leading to misdiagnosis and delayed access to disease-modifying therapies. We report the first genetically confirmed case of ATTRv mimicking amyotrophic lateral sclerosis (ALS) in Saudi Arabia. A 47-year-old male presented with progressive right-sided limb weakness (proximal > distal) and dysarthria over 18\u00a0months. Neurological examination revealed fasciculations, distal atrophy, and brisk reflexes with normal muscle tone and no spasticity. Electrophysiological studies demonstrated a length-dependent sensorimotor axonal neuropathy with widespread denervation changes involving bulbar, cervical, and lumbosacral regions. Brain and spine MRI, along with whole-body CT, excluded structural or paraneoplastic causes. Genetic testing identified a pathogenic heterozygous variant in the TTR gene: NM_000371.4:c.424G\u00a0>\u00a0A (p.Val142Ile). Transthoracic echocardiography revealed mild concentric left ventricular hypertrophy. There was no clinical evidence of autonomic, renal, or ocular involvement. This case underscores the importance of considering ATTRv in patients presenting with atypical MND, particularly when clinically significant sensory symptoms, absent upper motor neuron signs, or unexplained cardiac abnormalities are present. Early diagnosis enables access to targeted therapies such as TTR stabilizers and gene-silencing agents, which can alter disease trajectory.\n\nID: 41905645\nTitle: Six months of experience at a specialized daytime care center for people with amyotrophic lateral sclerosis (ALS) in the Community of Madrid.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that affects motor neurons, leading to motor deterioration and a reduced quality of life. In the Community of Madrid, the ALS Network was established to improve patient care. In April 2024, the Specialised Day Care Centre for ALS (CEADELA) was inaugurated, complementing the care provided by the ALS Network. The aim of this study was to describe the experience of CEADELA during its first six months. A retrospective descriptive study was conducted on a cohort of CEADELA patients between April and October 2024. Clinical, functional, and therapeutic data were analysed, along with overall satisfaction levels. A total of 91 patients were included, with a mean age of 65.2 years (SD 11); of these, 59 (64.8%) were men. Most had spinal-onset ALS and were receiving treatment with riluzole. A significant increase was observed in the use of physiotherapy, speech therapy, and occupational therapy after referral to the centre. Functionality significantly declined over six months. The mortality rate was 12.1% (18.2% opted for assisted dying). Overall, 76 patients (83.5%) responded to the survey, with 100% reporting satisfaction or high satisfaction with the centre (80.2% very satisfied and 18.4% satisfied). CEADELA has improved access to specialised therapies with a high level of satisfaction, although disease progression remains a challenge. The need to continue developing integrated, evidence-based care models to optimise ALS management is highlighted.\n\nID: 41892827\nTitle: Biomechanical Voice Parameters as Potential Biomarkers for Phenotype Differentiation in Amyotrophic Lateral Sclerosis: A Cross-Sectional Study.\nAbstract: Background/Objectives: Amyotrophic lateral sclerosis (ALS) is a clinically heterogeneous neurodegenerative disease in which bulbar involvement frequently affects speech and voice production. Although acoustic voice analysis can detect phonatory alterations in ALS, its ability to differentiate clinical phenotypes remains limited. This study investigated whether biomechanical voice parameters provide complementary information for characterizing bulbar involvement across bulbar-onset ALS (ALS-B) and spinal-onset ALS (ALS-S) and explored their association with clinical and functional measures. Methods: This cross-sectional observational study included 50 patients with ALS (20 ALS-B, 30 ALS-S) and 50 controls with non-neurological voice disorders. Sustained vowel phonation was analyzed using acoustic measures and biomechanical voice parameters derived from a standardized model of vocal fold vibration. Perceptual voice severity was assessed using the GRBAS scale, while functional status was evaluated with the ALS Functional Rating Scale-Revised (ALSFRS-R) and the Barthel Index. Associations with clinical measures were explored in secondary analyses. Results: Compared with controls, ALS patients showed significant differences in acoustic measures and several biomechanical parameters related to glottal closure and vibratory stability. Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability. Unexpectedly, ALS-B showed greater perceptual voice severity and higher Barthel Index scores than ALS-S, while no differences were observed in global ALSFRS-R total scores. Conclusions: Biomechanical voice analysis appears to capture physiologically meaningful alterations in vocal fold function in ALS and provides complementary information for characterizing bulbar motor involvement across clinical phenotypes, particularly ALS-B disease. When combined with acoustic and clinical assessments, this approach may enhance the evaluation of bulbar involvement and functional status in ALS.\n\nID: 41882018\nTitle: RanBP2-dependent annulate lamellae drive nuclear pore assembly and nuclear expansion.\nAbstract: Nuclear pore complexes (NPCs) enable nucleocytoplasmic transport. While NPCs primarily localize to the nuclear envelope (NE), they also appear in cytoplasmic endoplasmic reticulum (ER) membranes called annulate lamellae (AL). Though discovered in the mid-20th century, AL's function and biogenesis remain unclear. Previously considered exclusive to embryonic and malignant cells, we find AL in somatic mammalian cells. Under normal conditions, AL store pre-assembled AL-NPCs that integrate into the NE, producing approximately one-third of newly formed nuclear pores and supporting nuclear expansion during G1. Upon pathological stimuli, AL transfer to the NE is impaired, leading to their cytoplasmic accumulation. RanBP2 (Nup358) is essential for AL biogenesis, with its phenylalanine-glycine repeats promoting AL-NPC scaffold oligomerization. ER-associated Climp63 (CKAP4) directs AL-NPCs to ER sheets and the NE. This AL-driven nuclear pore formation is complementary to the canonical routes, constituting a distinct NPC assembly pathway. Our work uncovers the biogenesis mechanism of AL and the nuclear function of this key cellular organelle.\n\nID: 41843813\nTitle: ALS motor phenotypes: a revised 'OPM' classification.\nAbstract: Defining motor phenotypes in amyotrophic lateral sclerosis (ALS) is important for individualized care and optimal therapeutic trial design. The \"ALS-OPM\" classification is based on the onset region (O), the propagation of motor symptoms (P), and the degree of clinical upper (UMN) and/or lower (LMN) motor neuron dysfunction (M). An international ALS expert focus group was held in September 2025, followed by a consensus process through which revisions of the OPM classification were finalized. Onset (O1-4) identifies first motor symptoms as relating to the head (O1), distal/proximal arm (O2d/p), respiratory/axial trunk (O3r/a), or distal/proximal leg (O4d/p). Onset symptoms are defined by weakness or slowed, poorly coordinated voluntary movements in the muscles of the head, arm, trunk, or leg, including dysarthria, dysphagia, dysphonia, dyspnea, and axial instability. Propagation (P1(n)) or absence of propagation (P0(n)) of motor symptoms from the onset region to another body region are designated, where n denotes the number of months from onset to propagation or assessment. The degree of UMN dysfunction (slowed, poorly coordinated voluntary movements, hyperreflexia and/or spastic muscle tone, emotional lability) and/or LMN dysfunction (weakness with associated muscle atrophy) is classified as follows: balanced UMN and LMN dysfunction (M0); dominant (M1d) or pure UMN dysfunction (M1p); dominant (M2d) or pure LMN dysfunction (M2p); and dissociated UMN/LMN dysfunction (M3), in which the arms and legs predominantly show LMN and UMN involvement, respectively. The revised ALS-OPM classification aims to make it routine, practical and feasible to capture phenotype in clinical practice and therapeutic trials.\n\nID: 41838635\nTitle: Comparing vowel intelligibility across interactive and non-interactive tasks in disordered speech.\nAbstract: The current study examines vowel intelligibility across interactive and non-interactive situations for individuals with dysarthria secondary to amyotrophic lateral sclerosis (PALS). The vowel space of these speakers is often characterized by centralization and lowering, negatively affecting intelligibility. In two experiments, listeners identified vowels produced by PALS in habitual speech (non-interactive), clear speech (non-interactive), and interactive matching. Clear speech and interactive matching elicited more intelligible vowels than habitual speech. Interactive matching productions were equal to or more intelligible than clear speech productions depending on vowel. These data represent a preliminary step to understanding how the dynamics of communicative interaction may shape vowel intelligibility.\n\nID: 41829459\nTitle: Quantification of Tongue Motor Dysfunction in Amyotrophic Lateral Sclerosis Using a Smartphone-Based Task and Deep Learning.\nAbstract: Bulbar dysfunction is a major complication of amyotrophic lateral sclerosis (ALS). This study aimed to develop and validate a simple, smartphone-based task for the objective assessment of tongue movements and to examine their association with clinical variables. 37 ALS patients and 20 age- and sex-matched controls performed a tongue lateralization task, recorded with a smartphone. A deep-learning U-Net++-based model was used for segmentation and feature extraction. The frequency and maximum amplitude of tongue movements were quantified. Clinical measures included the ALS Functional Rating Scale-revised (ALSFRS-r) bulbar sub-scores, tongue fasciculations, jaw jerk, and tongue \"spasticity\". Between-group differences and associations between tongue metrics and clinical features were assessed. The U-Net++-based model achieved robust segmentation performance. Patients showed lower tongue movement frequency than controls (0.14 vs. 0.40, t = -9.58, p < 0.001). Normalized frequency was associated with dysarthria (t = -3.13, p = 0.003) but not dysphagia (t = -1.05, p = 0.30). Normalized frequency (t = 2.77, p = 0.009) and tongue \"spasticity\" (t = -2.57, p = 0.015) were both associated with speech performance in a multiple-regression model (R = 0.51, adjusted R2 = 0.43). Our method provides an objective, minimally invasive measure of bulbar function in ALS, which correlates with clinical ratings and may detect subtle impairments not captured by standard assessments. This approach offers a promising tool for remote monitoring and may support more effective disease management.\n\nID: 42347833\nTitle: Validation of the German version of the Dimensional Apathy Scale (G-DAS): Application in amyotrophic lateral sclerosis.\nAbstract: Apathy is a common behavioural impairment in neurodegenerative conditions and is conceptualized within the Dimensional Apathy Framework as comprising Executive, Emotional and Initiation subtypes. The Dimensional Apathy Scale (DAS) is widely used to assess these domains, yet no validated German version has been available. This study aimed to translate and validate the German DAS (G-DAS) in control participants (HC) and to characterize apathy profiles in German-speaking people with amyotrophic lateral sclerosis (pwALS). Seventy-seven HC and 32 pwALS completed self-rated and caregiver-rated measures of apathy, depression, disinhibition and executive dysfunction. The G-DAS was translated using a multi-round back-translation procedure. Psychometric validation was undertaken in the HC cohort. A subsample of HC matched to pwALS on age and sex was used for between-group comparisons and for deriving exploratory reference thresholds. The G-DAS demonstrated good to high internal consistency across subscales (\u03b1\u2009=\u2009.76-.85) and total scores (self-rated: \u03b1\u2009=\u2009.88; caregiver-rated: \u03b1\u2009=\u2009.86). Convergent validity was supported by significant correlations with the Apathy Evaluation Scale and Frontal Systems Behavior subscales, particularly for the Initiation and Executive subscales. Divergent validity was evidenced by the absence of associations with anxiety and depression. PwALS showed significantly higher Executive and Initiation apathy compared with matched HC, whereas Emotional apathy did not differ. Exploratory threshold scores derived from matched HC indicated that up to 47% of pwALS exhibited clinically elevated Initiation apathy. The G-DAS is a reliable and valid German-language measure of multidimensional apathy. It effectively captures the characteristic Executive and Initiation apathy profile in ALS, supporting its clinical and research utility.\n\nID: 42212970\nTitle: DIGEST Grades Remain Stable With Inclusion of Moderately Thickened Liquids in the Videofluoroscopic Examination in Individuals With Amyotrophic Lateral Sclerosis.\nAbstract: The Dynamic Imaging Grade of Swallowing Toxicity (Version 2; DIGESTV2) is a videofluoroscopy (VF) scale that measures pharyngeal swallowing severity based on functional measures of swallowing safety and efficiency. Original validation is based on a standard VF testing protocol including thin liquid, puree, and solid consistencies. Given that thickened liquid bolus trials are common in VF clinical testing protocols, we sought to determine the agreement in DIGESTV2 grades with and without the inclusion of moderately thick liquid bolus trials on DIGESTV2 outcomes in people with amyotrophic lateral sclerosis (pALS). This study represents a secondary analysis of VF examinations from a prospective longitudinal study conducted in 109 pALS. VF evaluations contained 10 barium trials spanning three International Dysphagia Diet Standardisation Initiative (IDDSI) levels (0-7). Duplicate, independent, and blinded ratings were completed. DIGESTV2 Efficiency and Safety grading was then completed under two conditions-with and without the inclusion of moderately thick liquid bolus trials into DIGESTV2 grading-to produce two sets of DIGESTV2 ratings for each VF study. Descriptives, percent agreement, and a weighted Cohen's kappa were performed on DIGESTV2 grades. A total of 373 VF examinations were included in this analysis. DIGESTV2 grade percent agreement with and without IDDSI Level 3 was excellent for Safety (98.1%), Efficiency (93.8%), and Total (94.1%) grades. Kappa values for Safety, Efficiency, and Total grades were .96, .89, and .91, respectively, indicating excellent agreement across bolus trial inclusion methods. Standard inclusion of moderately thick liquid bolus trials did not significantly impact DIGESTV2 grading in this data set. These results add to the preliminary but growing evidence suggesting stability of DIGEST grading with alternate bolus protocols in another patient population. https://doi.org/10.23641/asha.32348451.\n\nID: 42202251\nTitle: Beyond Time Saved: Implementation, Equity, and the Utility Threshold for Nursing AI Scribes.\nAbstract: Schwabe et al's pre-post time-motion study of a domain-specific artificial intelligence (AI) speech assistant used by nurses in German long-term care provides one of the few real-world, full-shift evaluations of an AI scribe deployed to a nonphysician workforce, with paired objective observation and self-reported outcomes. This commentary points to the implications of these findings that extend well beyond the time savings headline. The study reports substantial reduction in self-reported documentation time and increased satisfaction with the documentation system, yet workplace satisfaction and the perception that AI scribes are \"a good idea to implement\" did not improve. Taken together, these findings show three undertheorized issues for AI scribe implementation in nursing and long-term care. First, postimplementation increases in time spent reviewing entries and retrieving information indicate that AI scribes redistribute cognitive effort from authoring to verification, with unknown consequences for satisfaction, mastery, and error detection. Second, the apparent paradox of rising documentation satisfaction alongside falling expectations of AI quality represents user calibration. Third, the substantial equity considerations of automatic speech recognition documentation reflect a broader trend of AI scribe studies that treat equity as a caveat, rather than treating equitable performance as empirically measurable and testable across variations in linguistic styles, dialects, and social linguistic dimensions. To advance the field, the next generation of nursing AI scribe research must treat documentation as a heterogeneous bundle of authoring, reviewing, retrieving, and verifying activities with distinct satisfaction and error profiles; specify and validate end-user-defined anchor utilities, rather than having a narrow focus on diffuse improvement; and treat equity testing and reporting of both automatic speech recognition systems and workforce adoption as standard reporting expectations, rather than caveats.\n\nID: 42167272\nTitle: Updated trends in the global prevalence and burden of mental disorders, 1990-2023: a systematic analysis for the Global Burden of Disease Study 2023.\nAbstract: The 2023 iteration of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) estimated prevalence, incidence, and health burden for 375 diseases and injuries, including 12 mental disorders. We assess past, current, and emerging trends in the prevalence and burden of mental disorders across sexes and age groups, for 21 regions, 204 countries and territories, and by Socio-demographic Index (SDI) quintile, from 1990 to 2023. Mental disorders included in GBD 2023 were anxiety disorders, major depressive disorder, dysthymia, bipolar disorder, schizophrenia, autism spectrum disorders, conduct disorder, attention-deficit hyperactivity disorder, anorexia nervosa, bulimia nervosa, idiopathic developmental intellectual disability, and a residual category of other mental disorders. A literature review identified epidemiological data for each disorder. These were analysed via a Bayesian meta-regression to estimate prevalence by disorder, sex, age, location, and year. Disorder-specific prevalence was multiplied by disability weights representing the severity of health loss associated with each disorder to estimate years lived with disability (YLDs). Deaths due to anorexia nervosa were assessed with a Cause of Death Ensemble modelling strategy to estimate deaths by sex, age, location, and year, and then multiplied by the standard life expectancy at age of death to estimate years of life lost (YLLs). YLDs equalled disability-adjusted life-years (DALYs) for all mental disorders except anorexia nervosa (the only mental disorder considered as an underlying cause of death in GBD), for which DALYs represented the sum of YLDs and YLLs. We presented prevalence, deaths, YLDs, YLLs, and DALYs as counts, age-specific rates per 100\u2008000 population, and age-standardised rates per 100\u2008000 population. We estimated 1\u00b717 billion (95% uncertainty interval 1\u00b706-1\u00b731) prevalent cases of mental disorders globally in 2023, equivalent to an age-standardised prevalence rate of 14\u2008210\u00b77 cases (12\u2008849\u00b75-15\u2008940\u00b71) per 100\u2008000 population. These estimates represented a 95\u00b75% (75\u00b70-121\u00b72) increase in prevalent cases and 24\u00b72% (11\u00b74-41\u00b74) increase in age-standardised prevalence rate between 1990 and 2023. All mental disorders showed increases in prevalent cases between 1990 and 2023, while notable increases were seen in age-standardised prevalence rates for anxiety disorders, major depressive disorder, dysthymia, anorexia nervosa, bulimia nervosa, schizophrenia, and conduct disorder. There were an estimated 171 million (127-228) DALYs due to mental disorders globally across sex and age in 2023, equivalent to an age-standardised DALY rate of 2070\u00b75 DALYs (1519\u00b71-2750\u00b75) per 100\u2008000 population. Mental disorders contributed to 6\u00b71% (4\u00b78-7\u00b76) of all-cause DALYs in 2023, making them the fifth leading cause of global DALYs (up from 12th in 1990). DALYs were almost entirely composed of YLDs. Mental disorders were the leading cause of YLDs in 2023 (up from second in 1990), explaining 17\u00b73% (14\u00b78-20\u00b76) of all-cause global YLDs. Leading causes of mental disorder DALYs were anxiety disorders (ranked 11th among the 304 diseases and injuries at Level 4 of the GBD cause hierarchy), major depressive disorder (15th), and schizophrenia (41st). Globally in 2023, mental disorder age-standardised DALY rates were higher among females (2239\u00b76 [1643\u00b77-3014\u00b71] per 100\u2008000) than among males (1900\u00b72 [1399\u00b78-2510\u00b78] per 100\u2008000), and peaked in the 15-19 years age group (2617\u00b73 [1850\u00b76-3696\u00b78] per 100\u2008000). All locations showed increased mental disorder DALY rates in 2023 compared with 1990, ranging across countries and territories from 1302\u00b74 (952\u00b77-1683\u00b77) per 100\u2008000 in Viet Nam to 3555\u00b78 (2661\u00b79-4715\u00b70) per 100\u2008000 in the Netherlands. Across SDI quintiles, DALY rates ranged from 1853\u00b70 (1352\u00b71-2469\u00b73) per 100\u2008000 for middle SDI to 2184\u00b71 (1606\u00b71-2890\u00b73) per 100\u2008000 for high SDI. A significant health burden was imposed by mental disorders in all countries and territories in 2023, irrespective of the health resources available. In some instances, this burden has increased over time and is unevenly distributed across populations. Stronger surveillance systems, particularly in low-income and middle-income countries, are required. Additionally, we need more coordinated and inclusive policies to reduce the burden through early treatment and prevention, tailored to sex and age differences across locations. Responding to the mental health needs of our global population, especially those most vulnerable, is an obligation, not a choice.

This study aims to evaluate the effectiveness of A Successful Swallowing with Effortful Training (ASSET) program, included in the 'The 365 Healthy Swallow Health Coach application' in preserving speech and swallowing abilities in ALS patients through self-training. In this 8-week quasi-experimental study, 13 participants were allocated to either the app-guided ASSET training group (n=7; three sessions per day, five days per week) or a usual-care control group (n=6) based on their clinical visit schedules. To evaluate changes over time and compare the two groups, linear mixed models were employed. Changes in ALS severity scale (ALSSS), Diadochokinetic (DDK) task, speech intensity, Speech Handicap Index-15, Dysphagia Handicap Index, Swallowing Quality of Life (SWAL-QOL), and Brief Inventory of Swallowing Assessment-15 were assessed. ALSSS speech scores was relatively preserved from 5.43 (95% CI 3.01-7.84) to 5.29 (95% CI 2.87-7.70) in the ASSET treatment group, but declined from 6.33 (95% CI 3.73-8.94) to 4.83 (95% CI 2.23-7.44) in the control group, with a significant group-by-time interaction (p=.017). DDK/tuh/and/kuh/were relatively preserved from 11.86 to 11.71 and from 12.29 to 11.57 respectively in ASSET group, but declined from 11.67 to 7.50 and from 11.83 to 7.17 in the control group, with significant interactions in/tuh/(p=.032) and/kuh/(p=.044). SWAL-QOL total score was relatively preserved from 155.86 to 149.71 in ASSET group, but declined from 154.67 to 125.17 in the control group, with a significant interaction (p=.011). The findings suggest that ASSET program may help preserve speech and swallowing function in patients with ALS. Future research should validate the ASSET program with a larger, adequately powered sample size.\n\nID: 41765421\nTitle: [Mechanism of action and clinical trial results of a new drug for amyotrophic lateral sclerosis (ALS), Mecobalamin (Rozebalamin\u00ae) for intramuscular injection, 25 mg].\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive, intractable neurodegenerative disease characterized by generalized muscle atrophy and weakness, dysarthria, dysphagia, and respiratory muscle paralysis. Respiratory dysfunction due to muscle weakness is the primary cause of death; without mechanical ventilation, death typically occurs within 2 to 5 years after onset. Mecobalamin, an active form of vitamin B12, is thought to suppress homocysteine-induced neuronal cell death in ALS by acting as a coenzyme for methionine synthase, which catalyzes the conversion of homocysteine to methionine. Since the 1990s, research on neurodegenerative diseases supported by Japan's Ministry of Health, Labour and Welfare has suggested that high-dose mecobalamin may confer clinical benefits in ALS. This led to the initiation of clinical development. A Phase II/III double-blind, placebo-controlled comparative trial was conducted, but did not meet its primary endpoint. Based on these trial findings, an investigator-initiated Phase III placebo-controlled, double-blind comparative trial was conducted primarily at Tokushima University Hospital, targeting patients who developed ALS within one year before starting the trial. The trial demonstrated the efficacy of high-dose mecobalamin in slowing the decline in the Revised ALS Functional Rating Scale total score, which was the primary endpoint. Safety was also confirmed. Based on these results, mecobalamin received regulatory approval in September 2024 for the indication \"slowing the progression of functional impairment in ALS.\" It is expected to offer a new treatment option for patients with ALS.\n\nID: 41718496\nTitle: Timing of communication and technology control support in ALS - a systematic review.\nAbstract: Objective: To review evidence on the optimal timing of interventions that support communication and technology control for people living with Amyotrophic Lateral sclerosis (ALS). Methods: A systematic review was conducted following a pre-registered protocol. Databases were searched for studies involving people living with ALS that addressed timing of assistive technology interventions for communication or technology control. Screening and data extraction were completed in duplicate, findings were synthesized using a thematic analysis, and relevant findings presented as a descriptive summary. Results: Twenty-eight studies met the inclusion criteria. Evidence focused overwhelmingly on communication support rather than wider assistive technology interventions. Need for a communication aid typically occurs between one and five years from diagnosis and the timing of this varies significantly according to the site of onset of ALS. There are significant variations in the timing of changes for individuals within these groupings and there are likely a larger number of groupings that would be clinically useful. A significant correlation between changes in speaking rate and intelligibility has been shown. Once changes to speech do start to occur then the time to the loss of functional speech appears relatively consistent across the types of ALS. Conclusion: Current best practice guidelines are not reflective of the findings of this review and do not support professionals in identifying how to provide timely support. Monitoring speech changes systematically may support timely intervention. There is potential for individual level predictive modeling to help support people living with ALS to be proactive and prepared for changes.\n\nID: 41681063\nTitle: Ultrasonographic Measurements of Tongue Thickness and Swallowing Dysfunction in Amyotrophic Lateral Sclerosis: A Feasibility Study.\nAbstract: To explore whether ultrasonographic measurements of tongue thickness are associated with swallowing function and related clinical domains in patients with amyotrophic lateral sclerosis (ALS), this feasibility study was conducted. Few studies have examined the usefulness of ultrasonographic tongue thickness measurement in patients with ALS, but its association with physiological measures remains unclear. Ten patients with ALS underwent tongue thickness measurement using ultrasonography. Clinical assessments including the Korean version of the ALS Functional Rating Scale-Revised (K-ALSFRS-R), Functional Oral Intake Scale (FOIS), Eating Assessment Tool-10 (EAT-10), Dysphagia Handicap Index, Korean version of the Swallowing Quality of Life Questionnaire, Mini Nutritional Assessment-Short Form (MNA-SF), handgrip strength, and bioelectrical impedance analysis for skeletal muscle index (SMI) were performed. Swallowing physiology was evaluated using the Modified Barium Swallow Impairment Profile (MBSImP), Penetration-Aspiration Scale. Simple and partial Pearson's correlation analyses as well as univariate regression were performed with adjustments for age, sex, and body mass index (BMI). Tongue thickness showed significant associations with multiple functional and systemic measures in the unadjusted analyses, including FOIS, EAT-10, MNA-SF, BMI, SMI, K-ALSFRS-R. After adjustment, the most consistent associations were observed with the MBSImP oral, pharyngeal, and combined phase scores. Tongue ultrasonography may serve as a radiation-free method to preliminarily assess bulbar involvement in ALS. Tongue thickness was most specifically associated with dysphagia outcomes, particularly MBSImP. Given the feasibility design and small sample size, larger longitudinal studies are warranted to confirm its clinical utility in monitoring the progression of dysphagia in patients with ALS.\n\nID: 41571758\nTitle: Cytoplasmic TDP-43 leads to early behavioral impairments without neurodegeneration in a serotonergic neuron-specific C. elegans model.\nAbstract: TDP-43 proteinopathies, such as amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), are marked by the pathological cytoplasmic accumulation of TAR DNA-binding protein 43 (TDP-43), leading to progressive neuronal dysfunction and degeneration. To investigate the early functional consequences of TDP-43 mislocalization, we generated Caenorhabditis elegans models expressing either wild-type human TDP-43 or a variant with a mutated nuclear localization signal (\u0394NLS), specifically in serotonergic neurons. These neurons were chosen because in C. elegans they regulate well-characterized behaviors, providing a straightforward readout of neuronal function. We found that expression of either TDP-43 variant impaired serotonin-dependent behaviors-including pharyngeal pumping, egg-laying, and locomotion slowing upon food encounter-with the cytoplasmic \u0394NLS form causing more severe deficits. These behavioral impairments are evident even while the serotonergic neurons remain apparently normal in structure, suggesting that neuronal dysfunction precedes overt neurodegeneration. Moreover, the serotonergic HSN neurons that control egg-laying were also partially responsive to the selective serotonin reuptake inhibitor fluoxetine, suggesting that neurotransmitter release remains functional to some extent. Altogether, our findings demonstrate that TDP-43 expression causes neuronal dysfunction leading to behavioral deficits, even in the absence of detectable structural pathology and that its mislocalization to the cytoplasm results in more severe behavioral impairments. This C. elegans model provides a genetically tractable system to dissect early mechanisms of TDP-43-mediated neuronal dysfunction and to identify therapeutic strategies targeting predegenerative stages of ALS/FTD.\n\nID: 41562880\nTitle: Dysphagia and Dysarthria in Neurodegenerative Diseases: A Multisystem Network Approach to Assessment and Management.\nAbstract: Dysphagia and dysarthria are common, co-occurring manifestations in neurodegenerative diseases, resulting from damage to distributed neural networks involving cortical, subcortical, cerebellar, and brainstem regions. These disorders profoundly affect patient health and quality of life through complex sensorimotor impairments. Objective: The aims was to provide a comprehensive, evidence-based review of the neuroanatomical substrates, pathophysiology, diagnostic approaches, and management strategies for dysphagia and dysarthria in neurodegenerative diseases with emphasis on their multisystem nature and integrated treatment approaches. Methods: A narrative literature review was conducted using PubMed, Scopus, and Web of Science databases (2000-2024), focusing on Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), progressive supranuclear palsy (PSP), and multiple system atrophy (MSA). Search terms included \"dysphagia\", \"dysarthria\", \"neurodegenerative diseases\", \"neural networks\", \"swallowing control\" and \"speech production.\" Studies on neuroanatomy, pathophysiology, diagnostic tools, and therapeutic interventions were included. Results: Contemporary neuroscience demonstrates that swallowing and speech control involve extensive neural networks beyond the brainstem, including bilateral sensorimotor cortex, insula, cingulate gyrus, basal ganglia, and cerebellum. Disease-specific patterns reflect multisystem involvement: PD affects basal ganglia and multiple brainstem nuclei; ALS involves cortical and brainstem motor neurons; MSA causes widespread autonomic and motor degeneration; PSP produces tau-related damage across multiple brain regions. Diagnostic approaches combining fiberoptic endoscopic evaluation, videofluoroscopy, acoustic analysis, and neuroimaging enable precise characterization. Management requires multidisciplinary Integrated teams implementing coordinated speech-swallowing therapy, pharmacological interventions, and assistive technologies. Conclusions: Dysphagia and dysarthria in neurodegenerative diseases result from multifocal brain damage affecting distributed neural networks. Understanding this multisystem pathophysiology enables more effective integrated assessment and treatment approaches, enhancing patient outcomes and quality of life.\n\nID: 41511908\nTitle: Utility of Simple Speech Measures in Amyotrophic Lateral Sclerosis Assessment: Focus on Alternating Motion Rate as a Screening Tool.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive degeneration of motor neurons. Early detection of bulbar symptoms is crucial for timely diagnosis and intervention; however, variability in symptom progression complicates clinical assessment. This retrospective observational study aimed to classify patients with ALS into three groups - spinal onset, spinal onset with bulbar involvement, and bulbar onset - and to identify speech evaluation metrics that effectively differentiate these groups. Data from 68 patients with ALS were retrospectively analyzed. Speech samples were collected and evaluated for alternating motion rate (AMR), maximum phonation time (MPT), nasality, maximum tongue pressure (MTP), speech rate, and speech intelligibility. Group comparisons and receiver operating characteristic (ROC) curve analyses were conducted to assess discriminatory ability. AMR significantly differed among the three groups, with the spinal-onset group demonstrating the highest rates and the bulbar-onset group showing the lowest rates. ROC analysis indicated that AMR exhibited excellent discriminatory power, particularly in distinguishing spinal-from bulbar-onset ALS. Significant differences were also observed in MTP, nasality, speech rate, and speech intelligibility, although some metrics were less effective in differentiating the intermediate group. No significant group differences were found in MPT. These findings suggest that the AMR is a sensitive and easily administered measure for detecting bulbar symptoms and distinguishing ALS subtypes. The intermediate characteristics observed in the spinal-onset with bulbar involvement group support this classification as a distinct clinical phenotype. Combining AMR with secondary measures such as MTP, nasality, speech rate, and speech intelligibility may enhance early detection of bulbar symptoms and improve clinical decision-making.\n\nID: 41500873\nTitle: Voice-Based Prediction of Survival in Amyotrophic Lateral Sclerosis (ALS) Patients Using Biomechanical Acoustic Markers.\nAbstract: To evaluate whether voice-derived acoustic and biomechanical features can serve as non-invasive biomarkers for mortality-risk prediction and survival stratification in patients with amyotrophic lateral sclerosis (ALS). We conducted a retrospective study including 50 ALS patients evaluated in a phoniatrics consultation with available sustained vowel recordings, demographic data, and functional assessments. Nested logistic regression models were developed to predict clinical outcomes, progressively incorporating demographic variables, functional indices (Grade, Roughness, Breathiness, Asthenia, Strain, and Barthel), acoustic features (fundamental frequency, jitter, shimmer, harmonics-to-noise ratio), and biomechanical voice parameters (Pr1-Pr22). Model performance was assessed using receiver operating characteristic curves and area under the curve (AUC) comparisons via DeLong tests. Stepwise Akaike Information Criterion\u00a0(StepAIC) was applied to optimize the final model. A Cox proportional hazards model was used to evaluate the association between voice parameters and survival time. The final StepAIC model, which included a subset of biomechanical features, achieved excellent predictive performance (AUC\u00a0=\u00a00.903, 95% confidence interval: 0.816-0.989), significantly outperforming baseline and acoustic-only models. Bootstrapping confirmed the model's robustness and generalizability. Cox regression analysis showed that the derived risk scores stratified patients into tertiles with significantly different survival probabilities (log-rank P\u00a0<\u00a00.0001; hazard ratio for high vs. low-risk group\u00a0=\u00a011.2). Biomechanical voice features are strong predictors of mortality in ALS and outperform traditional clinical and acoustic indices. These findings support the integration of voice analysis into ALS monitoring protocols as a non-invasive, cost-effective, and scalable prognostic tool.\n\nID: 41375893\nTitle: Rehabilitation in Amyotrophic Lateral Sclerosis: Recommendations for Clinical Practice and Further Research.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative condition characterized by the degeneration of upper and lower motor neurons. This degeneration leads to a gradual muscle weakness, dysarthria, dysphagia, respiratory insufficiency, and, in some patients, alterations in cognitive and behavioral performance. Regardless of advancements made in pharmacological and gene-targeted interventions, a definitive curative treatment remains elusive. Consequently, rehabilitation plays a pivotal role in preserving autonomy, participation, and overall quality of life. This review outlines the current evidence and clinical approaches related to multidisciplinary rehabilitation in ALS. It covers physical and occupational therapy, respiratory, speech and language, psychological, and palliative care domains. Evidence supports moderate tailored exercise programs, early respiratory therapy, and structured management of mobility deficits, spasticity, pain, dysphagia, and communication impairments as key elements of symptomatic treatment. Psychological and social support, which includes the involvement of caregivers and relatives, enhances emotional well-being and coping resilience. Even with progressive development of gene-targeted and disease-modifying therapies, rehabilitation will stay relevant for maintaining long-term motor function. This review highlights the need for standardized, evidence-based rehabilitation protocols and intensified neurorehabilitation research to strengthen clinical outcomes and quality of life as key therapeutic goals in ALS management.\n\nID: 41343582\nTitle: Comprehensive analysis platform to understand, remedy, and eliminate amyotrophic lateral sclerosis (CAPTURE ALS): Study protocol for a Canadian multicenter, multimodal, longitudinal observational study.\nAbstract: The marked heterogeneity of Amyotrophic Lateral Sclerosis (ALS) combined with a lack of biomarkers are key contributing factors to the lack of disease-modifying treatments. The Comprehensive Analysis Platform to Understand Remedy and Eliminate ALS (CAPTURE ALS) is a Canadian platform designed to create the most comprehensive picture of people living with ALS with the objective of facilitating ALS research initiatives worldwide. The main aims of CAPTURE ALS include: (1) to characterize ALS and healthy controls with biosamples and data in order to provide the most comprehensive picture of individuals living with ALS to date; (2) to create a de-identified database and biosample repository linked to detailed clinical information; and (3) to develop and implement an inclusive and transparent participant engagement strategy to be active throughout all stages of CAPTURE ALS. CAPTURE ALS is a prospective, multicenter, observational, longitudinal study. People living with ALS, or a related disease and healthy controls undergo a harmonized protocol including the collection of detailed clinical information, neurological and cognitive examination, speech recording, advanced magnetic resonance imaging, and biosampling. Data and samples are stored in a biobank operating under an open science governance framework. An inclusive and transparent participant engagement strategy was designed and implemented throughout all stages of CAPTURE ALS. Four sites are operating in the consortium with a fifth being onboarded. The target enrollment is 120 affected participants and 50 controls, with the first participant visit having occurred in March 2022. Recruitment is ongoing. CAPTURE ALS is a scalable clinical research platform that connects scientists and patients to facilitate efficient translational research. The unique and deeply phenotyped data and biosamples are a global resource towards the development of biomarkers and understanding ALS biology. This study is registered at clinicaltrials.gov (NCT: NCT05204017).\n\nID: 41341425\nTitle: Exploring Speech Biosignatures for Traumatic Brain Injury and Neurodegeneration: Pilot Machine Learning Study.\nAbstract: Speech features are increasingly linked to neurodegenerative and mental health conditions, offering the potential for early detection and differentiation between disorders. As interest in speech analysis grows, distinguishing between conditions becomes critical for reliable diagnosis and assessment. This pilot study explores speech biosignatures in two distinct neurodegenerative conditions: (1) mild traumatic brain injuries (eg, concussions) and (2) Parkinson disease (PD) as the neurodegenerative condition. The study included speech samples from 235 participants (97 concussed and 94 age-matched healthy controls, 29 PD and 15 healthy controls) for the PaTaKa test and 239 participants (91 concussed and 104 healthy controls, 29 PD and 15 healthy controls) for the Sustained Vowel (/ah/) test. Age-matched healthy controls were used. Young age-matched controls were used for concussion and respective age-matched controls for neurodegenerative participants (15 healthy samples for both tests). Data augmentation with noise was applied to balance small datasets for neurodegenerative and healthy controls. Machine learning models (support vector machine, decision tree, random forest, and Extreme Gradient Boosting) were employed using 37 temporal and spectral speech features. A 5-fold stratified cross-validation was used to evaluate classification performance. For the PaTaKa test, classifiers performed well, achieving F 1-scores above 0.9 for concussed versus healthy and concussed versus neurodegenerative classifications across all models. Initial tests using the original dataset for neurodegenerative versus healthy classification yielded very poor results, with F 1-scores below 0.2 and accuracy under 30% (eg, below 12 out of 44 correctly classified samples) across all models. This underscored the need for data augmentation, which significantly improved performance to 60%-70% (eg, 26-31 out of 44 samples) accuracy. In contrast, the Sustained Vowel test showed mixed results; F 1-scores remained high (more than 0.85 across all models) for concussed versus neurodegenerative classifications but were significantly lower for concussed versus healthy (0.59-0.62) and neurodegenerative versus healthy (0.33-0.77), depending on the model. This study highlights the potential of speech features as biomarkers for neurodegenerative conditions. The PaTaKa test exhibited strong discriminative ability, especially for concussed versus neurodegenerative and concussed versus healthy tasks, whereas challenges remain for neurodegenerative versus healthy classification. These findings emphasize the need for further exploration of speech-based tools for differential diagnosis and early identification in neurodegenerative health.\n\nID: 41283495\nTitle: Acoustic Vowel Metrics as Correlates of Dysphagia and Dysarthria in Brainstem Neurodegenerative Diseases.\nAbstract: Background/Objectives: Swallowing and speech rely on shared brainstem circuits coordinating oropharyngeal motor functions. In neurodegenerative diseases affecting the brainstem-such as progressive supranuclear palsy (PSP), amyotrophic lateral sclerosis (ALS), and multiple system atrophy (MSA)-bulbar dysfunction often impairs tongue propulsion and motility, affecting both swallowing (dysphagia) and phonation (dysarthria). This study aimed to investigate whether vowel-based acoustic features are associated with swallowing severity in brainstem-related disorders and to explore their potential as surrogate markers of bulbar involvement. Methods: This was a cross-sectional observational study. Thirty-one patients (13 PSP, 12 ALS, 6 MSA) underwent clinical dysarthria assessment, acoustic analysis of the first (F1) and second (F2) formants during sustained phonation of /a/, /i/, /e/, and /u/, and swallowing evaluation using standardized clinical scales (DOSS, FOIS, ASHA-NOMS) and fiberoptic endoscopic evaluation (Pooling Score, Penetration-Aspiration Scale). The vowel space area (tVSA, qVSA) and Formant Centralization Ratio (FCR) were computed. Results: Significant correlations emerged between acoustic vowel metrics and dysphagia severity, especially for liquids. The FCR showed strong correlations with DOSS (\u03c1 = -0.660, p < 0.0001), FOIS (\u03c1 = -0.531, p = 0.002), ASHA-NOMS (\u03c1 = -0.604, p < 0.0001), and instrumental scores for liquids: the Pooling Score (\u03c1 = 0.538, p = 0.002) and PAS (\u03c1 = 0.630, p < 0.0001). VSA measures were also associated significantly with liquid swallowing impairment. F2u correlated with dysarthria severity and all liquid-related dysphagia scores. Conclusions: Vowel-based acoustic parameters, particularly FCR and F2u, reflect the shared neuromotor substrate of articulation and swallowing. Acoustic analysis may support early detection and monitoring of bulbar dysfunction, especially where instrumental assessments are limited.\n\nID: 41269662\nTitle: Unrevealing the sequence of dysphagia progression in ALS: an event-based, FEES-driven staging approach.\nAbstract: Dysphagia drives morbidity and mortality in amyotrophic lateral sclerosis (ALS), yet staging systems treat it as a binary milestone and do not capture its trajectory. Reports diverge on the earliest abnormality, with some citing cohesive-bolus inefficiency and others thin-liquid impairment. Furthermore, how these findings relate to patient-perceived dysphagia remains unclear. In a prospective cohort, 78 incident ALS patients underwent one or more fiberoptic endoscopic evaluations of swallowing (FEES), yielding 108 assessments. Pharyngeal residue for four consistencies was rated with a validated scale. An event-based model (EBM) inferred the temporal order of abnormalities and defined a five-stage, FEES-based dysphagia staging system (DSS). Construct, convergent, discriminant, and prognostic validity were tested against established measures; responsiveness was assessed in patients with longitudinal FEES. The EBM identified a consistent sequence of swallowing impairment: solids, semisolids, liquids, saliva. Patient-perceived dysphagia occurred in 38% of DSS 1-2 evaluations versus 100% of DSS 3-4. The DSS showed construct validity by distinguishing bulbar- from spinal-onset ALS and convergent validity with the ALSFRS-R bulbar subscore and LMN bulbar score. Discriminant validity was supported by weak, non-significant associations with spinal/respiratory measures. Agreement with King's staging was moderate, and all King's stage IV patients mapped to DSS stages 3-4. The DSS was responsive to change (Stuart-Maxwell \u03c7\u00b2 = 11.034; p\u2009=\u20090.026). The EBM reconciles prior discrepancies: pathophysiology begins with solids, whereas symptom recognition typically coincides with liquid-phase residue. The FEES-based DSS is reproducible and clinically meaningful for tracking bulbar involvement and identifying higher-risk patients.\n\nID: 41259564\nTitle: Fiberoptic endoscopic evaluation of swallowing in amyotrophic lateral sclerosis: comparison with older people with dysphagia and relationship with time since diagnosis.\nAbstract: (1) to compare the findings of the instrumental swallowing assessment between individuals with amyotrophic lateral sclerosis (ALS) and older dysphagic adults without neurological diagnosis; (2) to compare the onset of pharyngeal response, pharyngeal residues, and the level of oral intake in relation to the time since diagnosis in the ALS group. This cross-sectional, retrospective study collected data from medical records. Altogether, 101 individuals with dysphagia were included and stratified into two groups: the first had 56 patients diagnosed with ALS, and the second had 45 older adults. Dysphagia signs were analyzed through fiberoptic endoscopic evaluation of swallowing, using four food consistencies, classified by the International Dysphagia Diet Standardisation Initiative (IDDSI). Pharyngeal residues were classified by the Yale Pharyngeal Residue Severity Rating Scale (YPRSRS), and oral intake by the Functional Oral Intake Scale (FOIS). The ALS group had differences in multiple swallows with one IDDSI consistency; posterior oral leakage, pharyngeal residues, and laryngeal penetration with three consistencies; and aspiration with one consistency. Individuals with more than 3 years since diagnosis had differences in the onset of the pharyngeal response in the pyriform sinuses, moderate pharyngeal residues, and oral intake. The ALS group had significant differences in the occurrence of multiple swallows, posterior oral leakage, pharyngeal residues, penetration, and aspiration with three IDDSI consistencies. Furthermore, the time since diagnosis was a determining factor for all three parameters.

The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023 provides cause-specific mortality estimates measured in counts, rates, and years of life lost (YLLs). GBD 2023 aimed to enhance our understanding of the relationship between age and cause of death by quantifying the probability of dying before age 70 years (70q0) and the mean age at death by cause and sex. This study enables comparisons of the impact of causes of death over time, offering a deeper understanding of how these causes affect global populations. GBD 2023 produced estimates for 292 causes of death disaggregated by age-sex-location-year in 204 countries and territories and 660 subnational locations for each year from 1990 until 2023. We used a modelling tool developed for GBD, the Cause of Death Ensemble model (CODEm), to estimate cause-specific death rates for most causes. We computed YLLs as the product of the number of deaths for each cause-age-sex-location-year and the standard life expectancy at each age. Probability of death was calculated as the chance of dying from a given cause in a specific age period, for a specific population. Mean age at death was calculated by first assigning the midpoint age of each age group for every death, followed by computing the mean of all midpoint ages across all deaths attributed to a given cause. We used GBD death estimates to calculate the observed mean age at death and to model the expected mean age across causes, sexes, years, and locations. The expected mean age reflects the expected mean age at death for individuals within a population, based on global mortality rates and the population's age structure. Comparatively, the observed mean age represents the actual mean age at death, influenced by all factors unique to a location-specific population, including its age structure. As part of the modelling process, uncertainty intervals (UIs) were generated using the 2\u00b75th and 97\u00b75th percentiles from a 250-draw distribution for each metric. Findings are reported as counts and age-standardised rates. Methodological improvements for cause-of-death estimates in GBD 2023 include a correction for the misclassification of deaths due to COVID-19, updates to the method used to estimate COVID-19, and updates to the CODEm modelling framework. This analysis used 55\u2008761 data sources, including vital registration and verbal autopsy data as well as data from surveys, censuses, surveillance systems, and cancer registries, among others. For GBD 2023, there were 312 new country-years of vital registration cause-of-death data, 3 country-years of surveillance data, 51 country-years of verbal autopsy data, and 144 country-years of other data types that were added to those used in previous GBD rounds. The initial years of the COVID-19 pandemic caused shifts in long-standing rankings of the leading causes of global deaths: it ranked as the number one age-standardised cause of death at Level 3 of the GBD cause classification hierarchy in 2021. By 2023, COVID-19 dropped to the 20th place among the leading global causes, returning the rankings of the leading two causes to those typical across the time series (ie, ischaemic heart disease and stroke). While ischaemic heart disease and stroke persist as leading causes of death, there has been progress in reducing their age-standardised mortality rates globally. Four other leading causes have also shown large declines in global age-standardised mortality rates across the study period: diarrhoeal diseases, tuberculosis, stomach cancer, and measles. Other causes of death showed disparate patterns between sexes, notably for deaths from conflict and terrorism in some locations. A large reduction in age-standardised rates of YLLs occurred for neonatal disorders. Despite this, neonatal disorders remained the leading cause of global YLLs over the period studied, except in 2021, when COVID-19 was temporarily the leading cause. Compared to 1990, there has been a considerable reduction in total YLLs in many vaccine-preventable diseases, most notably diphtheria, pertussis, tetanus, and measles. In addition, this study quantified the mean age at death for all-cause mortality and cause-specific mortality and found noticeable variation by sex and location. The global all-cause mean age at death increased from 46\u00b78 years (95% UI 46\u00b76-47\u00b70) in 1990 to 63\u00b74 years (63\u00b71-63\u00b77) in 2023. For males, mean age increased from 45\u00b74 years (45\u00b71-45\u00b77) to 61\u00b72 years (60\u00b77-61\u00b76), and for females it increased from 48\u00b75 years (48\u00b71-48\u00b78) to 65\u00b79 years (65\u00b75-66\u00b73), from 1990 to 2023. The highest all-cause mean age at death in 2023 was found in the high-income super-region, where the mean age for females reached 80\u00b79 years (80\u00b79-81\u00b70) and for males 74\u00b78 years (74\u00b78-74\u00b79). By comparison, the lowest all-cause mean age at death occurred in sub-Saharan Africa, where it was 38\u00b70 years (37\u00b75-38\u00b74) for females and 35\u00b76 years (35\u00b72-35\u00b79) for males in 2023. Lastly, our study found that all-cause 70q0 decreased across each GBD super-region and region from 2000 to 2023, although with large variability between them. For females, we found that 70q0 notably increased from drug use disorders and conflict and terrorism. Leading causes that increased 70q0 for males also included drug use disorders, as well as diabetes. In sub-Saharan Africa, there was an increase in 70q0 for many non-communicable diseases (NCDs). Additionally, the mean age at death from NCDs was lower than the expected mean age at death for this super-region. By comparison, there was an increase in 70q0 for drug use disorders in the high-income super-region, which also had an observed mean age at death lower than the expected value. We examined global mortality patterns over the past three decades, highlighting-with enhanced estimation methods-the impacts of major events such as the COVID-19 pandemic, in addition to broader trends such as increasing NCDs in low-income regions that reflect ongoing shifts in the global epidemiological transition. This study also delves into premature mortality patterns, exploring the interplay between age and causes of death and deepening our understanding of where targeted resources could be applied to further reduce preventable sources of mortality. We provide essential insights into global and regional health disparities, identifying locations in need of targeted interventions to address both communicable and non-communicable diseases. There is an ever-present need for strengthened health-care systems that are resilient to future pandemics and the shifting burden of disease, particularly among ageing populations in regions with high mortality rates. Robust estimates of causes of death are increasingly essential to inform health priorities and guide efforts toward achieving global health equity. The need for global collaboration to reduce preventable mortality is more important than ever, as shifting burdens of disease are affecting all nations, albeit at different paces and scales.

The patient was a 71-year-old female who presented with the chief complaint of limb weakness persisting for 4 months. She showed progressive limb weakness accompanied by muscle atrophy. Electromyography (EMG) revealed extensive neurogenic damage. Initial serum evaluation for neural-specific autoantibodies was positive for IgLON5-Ab (1\u2236100). Repeat testing confirmed IgLON5-Ab positivity with a titer of 1\u22361 000. The patient was diagnosed with anti-IgLON5 disease and treated with methylprednisolone and immunoglobulin, leading to clinical improvement. We found four relevant articles reporting a total of 11 similar cases. Thus, in this study, we analyzed a total of 12 cases, including our patient. Based on their clinical manifestations, these cases can be categorized into two types: amyotrophic lateral sclerosis(ALS)type and isolated bulbar type. Six cases-three males and three females-presented with the ALS type. Of these, three cases had diffuse limb weakness accompanied by muscle atrophy(two cases had diffuse hyperreflexia and one had a normal tendon reflex); one case presented with neck extensor weakness and bilateral asymmetric upper extremity weakness and was hyperreflexic at the bilateral patellar tendons; one case displayed asymmetric weakness in both lower limbs with normal deep reflexes, and one case exhibited neck weakness with hyperreflexia. EMG revealed diffuse lower motor neuron disease involving two or three regions. All patients tested positive for serum anti-IgLON5 antibodies. Four were also positive for anti-IgLON5 antibodies in cerebrospinal fluid, two were negative, and six were not tested. Among the 11 patients who received immunotherapy, 4 showed partial improvement in clinical symptoms, 2 exhibited transient improvement, 2 remained stable, and 3 showed no improvement. Testing for IgLON5-Ab should be considered among patients presenting with bulbar symptoms or ALS-like features, especially those with acute or subacute onset, rapid progression, autonomic dysfunction, vocal cord paralysis requiring tracheotomy, cognitive impairment, or involuntary movements. Early diagnosis and treatment may improve clinical symptoms and reduce adverse outcomes. \u672c\u6587\u62a5\u9053\u9996\u90fd\u533b\u79d1\u5927\u5b66\u5ba3\u6b66\u533b\u9662\u795e\u7ecf\u5185\u79d12021\u5e747\u6708\u6536\u6cbb\u76841\u4f8b\u8fd0\u52a8\u795e\u7ecf\u5143\u75c5\u6837\u8868\u578b\u7684\u6297IgLON5\u75c5\u75c5\u4f8b\u3002\u60a3\u8005\u4e3a71\u5c81\u5973\u6027\uff0c\u4e3b\u56e0\u80a2\u4f53\u65e0\u529b4\u4e2a\u6708\u5165\u9662\uff0c\u4e34\u5e8a\u8868\u73b0\u4e3a\u8fdb\u884c\u6027\u7684\u56db\u80a2\u65e0\u529b\u4f34\u808c\u8089\u840e\u7f29\uff0c\u808c\u7535\u56fe\u63d0\u793a\u5e7f\u6cdb\u795e\u7ecf\u6e90\u6027\u635f\u5bb3\uff0c\u8840\u6e05\u81ea\u8eab\u514d\u75ab\u6027\u8111\u708e\u76f8\u5173\u6297\u4f53\uff1aIgLON5-Ab\u9633\u6027\uff081\u2236100\uff09\uff0c\u590d\u67e5\u6297\u4f53\u6ef4\u5ea6\uff0c\u8840\u6e05IgLON5\u6297\u4f53IgG\u4e3a1\u22361 000\uff0c\u8bca\u65ad\u4e3a\u6297IgLON5\u75c5\uff0c\u5e94\u7528\u7532\u6cfc\u5c3c\u9f99\u53ca\u4e19\u79cd\u7403\u86cb\u767d\u6cbb\u7597\u6709\u597d\u8f6c\u3002\u540c\u65f6\u68c0\u7d22\u76f8\u5173\u6587\u732e4\u7bc7\uff0c\u5171\u62a5\u905311\u4f8b\u60a3\u8005\uff0c\u7ed3\u5408\u672c\u4f8b\u60a3\u8005\u517112\u4f8b\uff0c\u6839\u636e\u4e34\u5e8a\u8868\u73b0\u53ef\u5206\u4e3a2\u79cd\u7c7b\u578b\uff1a\u808c\u840e\u7f29\u4fa7\u7d22\u786c\u5316\uff08ALS\uff09\u578b\u548c\u5355\u7eaf\u5ef6\u9ad3\u578b\u3002\u67096\u4f8b\u8868\u73b0\u4e3aALS\u578b\uff0c\u7537\u60273\u4f8b\uff0c\u5973\u60273\u4f8b\uff0c\u5176\u4e2d\u56db\u80a2\u65e0\u529b\u4f34\u6709\u808c\u840e\u7f293\u4f8b\uff082\u4f8b\u56db\u80a2\u8171\u53cd\u5c04\u4ea2\u8fdb\uff0c1\u4f8b\u8171\u53cd\u5c04\u6b63\u5e38\uff09\uff0c\u53cc\u4e0a\u80a2\u4e0d\u5bf9\u79f0\u6027\u65e0\u529b\u4f34\u9888\u4f38\u808c\u65e0\u529b1\u4f8b\uff08\u53cc\u4fa7\u819d\u53cd\u5c04\u4ea2\u8fdb\uff09\uff0c\u53cc\u4e0b\u80a2\u4e0d\u5bf9\u79f0\u6027\u65e0\u529b1\u4f8b\uff08\u6df1\u53cd\u5c04\u6b63\u5e38\uff09\uff0c\u9888\u808c\u65e0\u529b1\u4f8b\uff08\u56db\u80a2\u6df1\u53cd\u5c04\u4ea2\u8fdb\uff09\uff1b\u808c\u7535\u56fe\u68c0\u67e5\u5747\u63d0\u793a\u4e0b\u8fd0\u52a8\u795e\u7ecf\u5143\u6027\u635f\u5bb3\uff0c\u7d2f\u53ca2\u62163\u4e2a\u533a\u57df\u3002\u6240\u6709\u60a3\u8005\u8840\u6e05\u6297IgLON5\u6297\u4f53\u5747\u4e3a\u9633\u6027\uff1b\u8111\u810a\u6db2\u6297IgLON5\u6297\u4f534\u4f8b\u9633\u6027\uff0c2\u4f8b\u9634\u6027\uff0c6\u4f8b\u672a\u68c0\u6d4b\u300211\u4f8b\u60a3\u8005\u7ed9\u4e88\u4e86\u514d\u75ab\u6cbb\u7597\uff0c4\u4f8b\u60a3\u8005\u4e34\u5e8a\u75c7\u72b6\u6709\u90e8\u5206\u6539\u5584\uff0c2\u4f8b\u6cbb\u7597\u540e\u77ed\u6682\u6027\u597d\u8f6c\uff0c2\u4f8b\u75c5\u60c5\u7a33\u5b9a\uff0c3\u4f8b\u60a3\u8005\u65e0\u6539\u5584\u3002\u8868\u73b0\u4e3a\u5ef6\u9ad3\u75c7\u72b6\u6216\u808c\u840e\u7f29\u4fa7\u7d22\u786c\u5316\u75c7\u7684\u60a3\u8005\uff0c\u5c24\u5176\u662f\u6025\u6027\u6216\u4e9a\u6025\u6027\u8d77\u75c5\uff0c\u8fdb\u5c55\u8fc5\u901f\uff0c\u6216\u5b58\u5728\u81ea\u4e3b\u795e\u7ecf\u529f\u80fd\u969c\u788d\u3001\u58f0\u5e26\u9ebb\u75f9\u9700\u8981\u6c14\u7ba1\u5207\u5f00\u3001\u8ba4\u77e5\u969c\u788d\u4ee5\u53ca\u4e0d\u81ea\u4e3b\u8fd0\u52a8\u7b49\u8868\u73b0\u65f6\uff0c\u9700\u8981\u8003\u8651\u5230\u6297IgLON5\u75c5\u7684\u53ef\u80fd\uff0c\u65e9\u671f\u8bca\u65ad\u53ca\u6cbb\u7597\u6216\u53ef\u6539\u5584\u60a3\u8005\u4e34\u5e8a\u75c7\u72b6\uff0c\u51cf\u5c11\u4e0d\u826f\u7ed3\u5c40\u3002.\n\nID: 40933233\nTitle: Digital speech assessments and machine learning for differentiation of neurodegenerative diseases.\nAbstract: Speech impairment is a prevalent symptom of neurological disorders, including Parkinson's disease (PD), Progressive Supranuclear Palsy (PSP), Huntington's disease (HD), and Amyotrophic Lateral Sclerosis (ALS), with mechanisms and severity varying across and within conditions. Scalable digital health tools and machine learning (ML) are essential for diagnosing and tracking neurodegenerative disease. A total of 92 individuals were included in this study (21 PSP, 21 PD, 18 HD, 15 ALS, and 16 healthy elderly controls (CTR)). The Rainbow Passage was collected on a digital device and analyzed to extract 12 speech features representing speech production. A set of Elastic Net ML models was trained on these speech features to differentiate between diagnostic classes. A specialized Support Vector Machine ML model was then developed to differentiate PSP from PD. Elastic Net models achieved a balanced accuracy of 77% over 5 diagnostic classes (group-specific sensitivities of 76% for PSP, 67% for PD, 83% for HD, 73% for ALS, and 88% for CTR) and 83% over 4 diagnostic classes (group-specific sensitivities of 83% for PSP-PD, 83% for HD, 73% for ALS, and 94% for CTR). The PSP vs. PD classification model demonstrated a balanced accuracy of 85%, with sensitivity of 88% for PSP and 82% for PD. Key speech features differentiated clinical conditions, with Total Voiced Time being the strongest positive feature for combined PSP-PD. In HD, ALS, and CTR, Ratio Extra Words, Pauses per Second, and Intelligibility were the most strongly differentiating features, respectively. Articulatory Rate emerged as the most distinguishing feature between PD and PSP. Our findings highlight the potential of digital health technology and ML in identifying and monitoring speech features in neurodegenerative diseases.\n\nID: 40729861\nTitle: Segmentation of the human tongue musculature using MRI: Field guide and validation in motor neuron disease.\nAbstract: This work addresses the challenge of reliably measuring the muscles of the human tongue, which are difficult to quantify due to complex interwoven muscle types. We introduce a new semi-automated method, enabled by a manually curated dataset of MRI scans to accurately measure five key tongue muscles, combining AI-assisted, atlas-based, and manual segmentation approaches. The method was tested and validated in a dataset of 178 scans and included segmentation validation (n\u00a0=\u00a0103) and clinical application (n\u00a0=\u00a0132) in individuals with motor neuron disease. We show that people with speech and swallowing deficits tend to have smaller muscle volumes and present a normalisation strategy that removes confounding demographic factors, enabling broader application to large MRI datasets. As the tongue is generally covered in neuroimaging protocols, our multi-contrast pipeline will allow for the post-hoc analysis of a vast number of datasets. We expect this work to enable the investigation of tongue muscle morphology as a marker in a wide range of diseases that implicate tongue function, including neurodegenerative diseases and pathological speech disorders.\n\nID: 40726766\nTitle: Listener effort measures clinically meaningful change of dysarthria in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative motor neuron disease that can cause progressive bulbar dysfunction and dysarthria, resulting in reduced quality of life. Quantitative motor speech analysis can identify features of dysarthria that worsen with ALS progression but are not, inherently, clinically meaningful. Listener effort (LE) is a clinician-rated feature describing how much effort the listener needs to exert to understand the dysarthric speaker. This study investigated whether LE could act as a clinically meaningful measure of ALS dysarthria that could be used as an outcome measure in clinical trials. The Everything ALS Speech Study obtained longitudinal clinical information and speech recordings from 292 participants. In a subset of 125 participants, we measured speaking rate and three speech-language pathologists (SLPs) with expertise in ALS rated LE. We also built and tested a LE prediction algorithm to predict the SLPs' rating of LE. In addition, all speech recordings and associated clinical data are now being made available to ALS researchers via the Everything ALS portal. LE intra- and inter-rater reliability was very high (ICC 0.94-0.95). LE correlated with other measures of dysarthria at baseline and changed over time in participants with ALS (slope 0.77 pts/month, SE = 0.15, P < 0.001) but not controls (slope 0.005 pts/month, SE = 0.02, P = 0.807). The slope of LE progression was faster in people with bulbar onset than non-bulbar onset ALS (1.66 points/month versus 0.42 pts/month; P < 0.001) but was similar in all participants who had bulbar dysfunction at baseline, regardless of ALS site of onset (1.52 pts/month for bulbar onset versus 0.98 pts/month for non-bulbar onset with current bulbar involvement; P = 0.36). The LE prediction model predicted the true LE, with an average R 2 of 0.83 \u00b1 0.07. Dysarthria is associated with decreased quality of life in people with ALS. Quantitative measures of dysarthria in ALS could be useful as ALS clinical trial outcome measures, providing insight into the progression of bulbar symptoms. Speaking rate quantifies progression but is variable across speaking stimuli, emotional states and contextual factors. LE is more inherently clinically meaningful, can be measured reliably by SLPs, changes quantitatively over time and is highly reproducible, thus may be useful as a clinical outcome assessment for ALS clinical trials. Furthermore, a LE prediction model is effective at predicting LE scores and should be validated on an external dataset.\n\nID: 40407667\nTitle: Relationship Between Voice Analysis and Functional Status in Patients with Amyotrophic Lateral Sclerosis.\nAbstract: Background: Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease affecting both upper and lower motor neurons, with bulbar dysfunction manifesting in up to 80% of patients. Dysarthria, characterized by impaired speech production, is common in ALS and often correlates with disease severity. Voice analysis has emerged as a promising tool for detecting disease progression and monitoring functional status. Methods: This study investigates acoustic and biomechanical voice alterations in ALS patients and their association with clinical measures of functional independence. A descriptive observational case series study was conducted, involving 43 ALS patients and 43 age and sex matched controls with non-neurological voice disorders. Sustained vowel /a/ recordings were obtained and analyzed using Voice Clinical Systems\u00ae and Praat software (version 6.2.22). Biomechanical and acoustic parameters were correlated with ALS Functional Rating Scale-Revised (ALSFRS-R) and Barthel Index scores. Results: Significant differences were observed between ALS and control groups (elevated muscle force and tension and interedge distance in non-ALS individuals). Between bulbar and spinal ALS subtypes, elevated values were observed in certain parameters in Bulbar ALS patients, indicating irregular vocal fold contact and weakened phonatory control, while spinal ALS exhibited increased values, suggesting higher phonatory muscle tension. Elevated biomechanical parameters were significantly correlated with low ALSFRS-R scores, suggesting a possible relationship between voice measures and functional decline. However, acoustic measurements showed no relationship with performance status. Conclusions: These results highlight the potential of voice analysis as a non-invasive, objective tool for monitoring ALS stage and differentiating between subtypes. Further research is needed to validate these findings and explore their clinical applications.\n\nID: 39867453\nTitle: A novel muscle network approach for objective assessment and profiling of bulbar involvement in ALS.\nAbstract: As a hallmark feature of amyotrophic lateral sclerosis (ALS), bulbar involvement significantly impacts psychosocial, emotional, and physical health. A validated objective marker is however lacking to characterize and phenotype bulbar involvement, positing a major barrier to early detection, progress monitoring, and tailored care. This study aimed to bridge this gap by constructing a multiplex functional mandibular muscle network to provide a novel objective measurement tool of bulbar involvement. A noninvasive electrophysiological technique-surface electromyography-was combined with graph network analysis to extract 48 features measuring the regulatory mechanisms, connectivity, integration, segregation, assortativity, and lateralization of the functional muscle network during a speech task. These features were clustered into 10 interpretable latent factors. To evaluate the utility of the muscle network as a bulbar measurement tool, a heterogenous ALS cohort, consisting of eight individuals with overt clinical bulbar symptoms and seven without, along with 10 neurologically healthy controls, was employed to train and validate statistical and machine learning algorithms to assess the disease effects on the network features and the relation of the network performance to the current clinical diagnostic standard and behavioral patterns of bulbar involvement. Significant disease effects were found on most network features. The most robust effects were manifested by reduced and more variable myoelectric activities, and reduced functional connectivity and integration of the muscle network. The 10 latent factors (1) demonstrated acceptably high efficacy for detecting bulbar neuromuscular changes across all clinically confirmed symptomatic cases and clinically silent prodromal cases (area under the curve = 0.89-0.91; F1 score = 0.85-0.87; precision = 0.84-0.86; recall = 0.87-0.88); and (2) selectively correlated with clinically meaningful behavioral patterns (conditional R 2 = 0.45-0.81). The functional muscle network shows promise for an objective quantifiable measurement tool to improve early detection and profiling of bulbar involvement across the prodromal and symptomatic stages. This tool has various strengths, including the use of a clinically readily available noninvasive instrument, fully automated data processing and analytics, and generation of interpretable objective outcome measures (i.e., latent factors), together rendering it highly scalable in routine clinical practice for assessing and monitoring of bulbar involvement.\n\nID: 39595845\nTitle: Voice Assessment in Patients with Amyotrophic Lateral Sclerosis: An Exploratory Study on Associations with Bulbar and Respiratory Function.\nAbstract: Speech production is a possible way to monitor bulbar and respiratory functions in patients with amyotrophic lateral sclerosis (ALS). Moreover, the emergence of smartphone-based data collection offers a promising approach to reduce frequent hospital visits and enhance patient outcomes. Here, we studied the relationship between bulbar and respiratory functions with voice characteristics of ALS patients, alongside a speech therapist's evaluation, at the convenience of using a simple smartphone. For voice assessment, we considered a speech therapist's standardized tool-consensus auditory-perceptual evaluation of voice (CAPE-V); and an acoustic analysis toolbox. The bulbar sub-score of the revised ALS functional rating scale (ALSFRS-R) was used, and pulmonary function measurements included forced vital capacity (FVC%), maximum expiratory pressure (MEP%), and maximum inspiratory pressure (MIP%). Correlation coefficients and both linear and logistic regression models were applied. A total of 27 ALS patients (12 males; 61 years mean age; 28 months median disease duration) were included. Patients with significant bulbar dysfunction revealed greater CAPE-V scores in overall severity, roughness, strain, pitch, and loudness. They also presented slower speaking rates, longer pauses, and higher jitter values in acoustic analysis (all p < 0.05). The CAPE-V's overall severity and sub-scores for pitch and loudness demonstrated significant correlations with MIP% and MEP% (all p < 0.05). In contrast, acoustic metrics (speaking rate, absolute energy, shimmer, and harmonic-to-noise ratio) significantly correlated with FVC% (all p < 0.05). The results provide supporting evidence for the use of smartphone-based recordings in ALS patients for CAPE-V and acoustic analysis as reliable correlates of bulbar and respiratory function.\n\nID: 38836001\nTitle: A multimodal approach to automated hierarchical assessment of bulbar involvement in amyotrophic lateral sclerosis.\nAbstract: As a hallmark feature of amyotrophic lateral sclerosis (ALS), bulbar involvement leads to progressive declines of speech and swallowing functions, significantly impacting social, emotional, and physical health, and quality of life. Standard clinical tools for bulbar assessment focus primarily on clinical symptoms and functional outcomes. However, ALS is known to have a long, clinically silent prodromal stage characterized by complex subclinical changes at various levels of the bulbar motor system. These changes accumulate over time and eventually culminate in clinical symptoms and functional declines. Detection of these subclinical changes is critical, both for mechanistic understanding of bulbar neuromuscular pathology and for optimal clinical management of bulbar dysfunction in ALS. To this end, we developed a novel multimodal measurement tool based on two clinically readily available, noninvasive instruments-facial surface electromyography (sEMG) and acoustic techniques-to hierarchically assess seven constructs of bulbar/speech motor control at the neuromuscular and acoustic levels. These constructs, including prosody, pause, functional connectivity, amplitude, rhythm, complexity, and regularity, are both mechanically and clinically relevant to bulbar involvement. Using a custom-developed, fully automated data analytic algorithm, a variety of features were extracted from the sEMG and acoustic recordings of a speech task performed by 13 individuals with ALS and 10 neurologically healthy controls. These features were then factorized into 10 composite outcome measures using confirmatory factor analysis. Statistical and machine learning techniques were applied to these composite outcome measures to evaluate their reliability (internal consistency), validity (concurrent and construct), and efficacy for early detection and progress monitoring of bulbar involvement in ALS. The composite outcome measures were demonstrated to (1) be internally consistent and structurally valid in measuring the targeted constructs; (2) hold concurrent validity with the existing clinical and functional criteria for bulbar assessment; and (3) outperform the outcome measures obtained from each constituent modality in differentiating individuals with ALS from healthy controls. Moreover, the composite outcome measures combined demonstrated high efficacy for detecting subclinical changes in the targeted constructs, both during the prodromal stage and during the transition from prodromal to symptomatic stages. The findings provided compelling initial evidence for the utility of the multimodal measurement tool for improving early detection and progress monitoring of bulbar involvement in ALS, which have important implications in facilitating timely access to and delivery of optimal clinical care of bulbar dysfunction.\n\nID: 38144173\nTitle: Validation of automated pipeline for the assessment of a motor speech disorder in amyotrophic lateral sclerosis (ALS).\nAbstract: Amyotrophic lateral sclerosis (ALS) frequently causes speech impairments, which can be valuable early indicators of decline. Automated acoustic assessment of speech in ALS is attractive, and there is a pressing need to validate such tools in line with best practices, including analytical and clinical validation. We hypothesized that data analysis using a novel speech assessment pipeline would correspond strongly to analyses performed using lab-standard practices and that acoustic features from the novel pipeline would correspond to clinical outcomes of interest in ALS. We analyzed data from three standard speech assessment tasks (i.e., vowel phonation, passage reading, and diadochokinesis) in 122 ALS patients. Data were analyzed automatically using a pipeline developed by Winterlight Labs, which yielded 53 acoustic features. First, for analytical validation, data were analyzed using a lab-standard analysis pipeline for comparison. This was followed by univariate analysis (Spearman correlations between individual features in Winterlight and in-lab datasets) and multivariate analysis (sparse canonical correlation analysis (SCCA)). Subsequently, clinical validation was performed. This included univariate analysis (Spearman correlation between automated acoustic features and clinical measures) and multivariate analysis (interpretable autoencoder-based dimensionality reduction). Analytical validity was demonstrated by substantial univariate correlations (Spearman's \u03c1\u2009>\u20090.70) between corresponding pairs of features from automated and lab-based datasets, as well as interpretable SCCA feature groups. Clinical validity was supported by strong univariate correlations between automated features and clinical measures (Spearman's \u03c1\u2009>\u20090.70), as well as associations between multivariate outputs and clinical measures. This novel, automated speech assessment feature set demonstrates substantial promise as a valid tool for analyzing impaired speech in ALS patients and for the further development of these technologies.\n\nID: 38062079\nTitle: A systematic review and narrative analysis of digital speech biomarkers in Motor Neuron Disease.\nAbstract: Motor Neuron Disease (MND) is a progressive and largely fatal neurodegeneritve disorder with a lifetime risk of approximately 1 in 300. At diagnosis, up to 25% of people with MND (pwMND) exhibit bulbar dysfunction. Currently, pwMND are assessed using clinical examination and diagnostic tools including the ALS Functional Rating Scale Revised (ALS-FRS(R)), a clinician-administered questionnaire with a single item on speech intelligibility. Here we report on the use of digital technologies to assess speech features as a marker of disease diagnosis and progression in pwMND. Google Scholar, PubMed, Medline and EMBASE were systematically searched. 40 studies were evaluated including 3670 participants; 1878 with a diagnosis of MND. 24 studies used microphones, 5 used smartphones, 6 used apps, 2 used tape recorders and 1 used the Multi-Dimensional Voice Programme (MDVP) to record speech samples. Data extraction and analysis methods varied but included traditional statistical analysis, CSpeech, MATLAB and machine learning (ML) algorithms. Speech features assessed also varied and included jitter, shimmer, fundamental frequency, intelligible speaking rate, pause duration and syllable repetition. Findings from this systematic review indicate that digital speech biomarkers can distinguish pwMND from healthy controls and can help identify bulbar involvement in pwMND. Preliminary evidence suggests digitally assessed acoustic features can identify more nuanced changes in those affected by voice dysfunction. No one digital speech biomarker alone is consistently able to diagnose or prognosticate MND. Further longitudinal studies involving larger samples are required to validate the use of these technologies as diagnostic tools or prognostic biomarkers.\n\nID: 38033517\nTitle: Co-designing a digital mental health platform, \"Momentum\", with young people aged 7-17: A qualitative study.\nAbstract: Digital mental health interventions (DMHIs) offer a promising alternative or adjunct treatment method to face-to-face treatment, overcoming barriers associated with stigma, access, and cost. This project is embedded in user experience and co-design to enhance the potential acceptability, usability and integration of digital platforms into youth mental health services. To co-design a digital mental health platform that provides self-directed, tailored, and modularised treatment for young people aged 7-17 years experiencing anxiety, depression and other related problems. Sixty-eight participants, aged 7-17 years, engaged in one of 20 co-design workshops. Eight workshops involved children (n\u2009\u2009=\u2009\u200926, m\u2009\u2009=\u2009\u20099.42 years, sd\u2009\u2009=\u2009\u20091.27) and 12 involved adolescents (n\u2009\u2009=\u2009\u200942, m\u2009\u2009=\u2009\u200914.57 years, sd\u2009\u2009=\u2009\u20091.89). Participants engaged in a variety of co-design activities (e.g., designing a website home page and rating self-report assessment features). Workshop transcripts and artefacts (e.g., participants' drawings) were thematically analysed using Gale et al.'s Framework Method in NVivo. Six themes were identified: Interactive; Relatable; Customisable; Intuitive; Inclusive; and Personalised, transparent and trustworthy content. The analysis revealed differences between children's and adolescents' designs and ideas, supporting the need for two different versions of the platform, with age-appropriate activities, features, terminology, and content. This research showcased co-design as a powerful tool to facilitate collaboration with young people in designing DMHIs. Two sets of recommendations were produced: 1) recommendations for the design, functionality, and content of youth DMHIs, supported by child- and adolescent-designed strategies; and 2) recommendations for clinicians and researchers planning to conduct co-design and intervention development research with children and adolescents.\n\nID: 37760880\nTitle: Acoustic Voice Analysis as a Useful Tool to Discriminate Different ALS Phenotypes.\nAbstract: Approximately 80-96% of people with amyotrophic lateral sclerosis (ALS) become unable to speak during the disease progression. Assessing upper and lower motor neuron impairment in bulbar regions of ALS patients remains challenging, particularly in distinguishing spastic and flaccid dysarthria. This study aimed to evaluate acoustic voice parameters as useful biomarkers to discriminate ALS clinical phenotypes. Triangular vowel space area (tVSA), alternating motion rates (AMRs), and sequential motion rates (SMRs) were analyzed in 36 ALS patients and 20 sex/age-matched healthy controls (HCs). tVSA, AMR, and SMR values significantly differed between ALS and HCs, and between ALS with prevalent upper (pUMN) and lower motor neuron (pLMN) impairment. tVSA showed higher accuracy in discriminating pUMN from pLMN patients. AMR and SMR were significantly lower in patients with bulbar onset than those with spinal onset, both with and without bulbar symptoms. Furthermore, these values were also lower in patients with spinal onset associated with bulbar symptoms than in those with spinal onset alone. Additionally, AMR and SMR values correlated with the degree of dysphagia. Acoustic voice analysis may be considered a useful prognostic tool to differentiate spastic and flaccid dysarthria and to assess the degree of bulbar involvement in ALS.\n\nID: 37607754\nTitle: Trigeminal Nerve Involvement in Bulbar-Onset Anti-IgLON5 Disease.\nAbstract: Anti-IgLON5 disease (IgLON5-D) may present with a bulbar-onset motor neuron disease-like phenotype, mimicking bulbar-onset amyotrophic lateral sclerosis. Recognition of their distinctive clinical and paraclinical features may help for differential diagnosis. We report 2 cases of atypical trigeminal neuropathy in bulbar-onset IgLON5-D. Trigeminal nerve involvement was assessed using comprehensive clinical, laboratory, electrophysiologic, and MRI workup. Both patients were referred for progressive dysphagia, sialorrhea, and hoarseness. They were treated with bilevel positive airway pressure for nocturnal hypoventilation. Patient 1 complained of continuous facial burning pain with allodynia, exacerbated by mastication and prolonged speech. Patient 2 reported no facial pain. Anti-IgLON5 autoantibodies (IgLON5-Abs) were positive in serum for both patients and CSF for patient 1. Cerebral MRI revealed bilateral T2 fluid-attenuated inversion recovery (FLAIR) hyperintensity and enlargement of trigeminal nerves without gadolinium enhancement in both patients. Needle myography showed fasciculations in masseter muscles. Blink-reflex study confirmed bilateral trigeminal neuropathy only in patient 2. Cortical laser-evoked potentials showed a bilateral small-fiber dysfunction in the trigeminal nerve ophthalmic branch in patient 1. In case of progressive atypical bulbar symptoms, the presence of a trigeminal neuropathy or trigeminal nerve abnormalities on MRI should encourage the testing of IgLON5-Abs in serum and CSF.\n\n\n\nID: 37309077\nTitle: A speech-based prognostic model for dysarthria progression in ALS.\nAbstract: Objective: We demonstrated that it was possible to predict ALS patients' degree of future speech impairment based on past data. We used longitudinal data from two ALS studies where participants recorded their speech on a daily or weekly basis and provided ALSFRS-R speech subscores on a weekly or quarterly basis (quarter-annually). Methods: Using their speech recordings, we measured articulatory precision (a measure of the crispness of pronunciation) using an algorithm that analyzed the acoustic signal of each phoneme in the words produced. First, we established the analytical and clinical validity of the measure of articulatory precision, showing that the measure correlated with perceptual ratings of articulatory precision (r = .9). Second, using articulatory precision from speech samples from each participant collected over a 45-90\u2009day model calibration period, we showed it was possible to predict articulatory precision 30-90 days after the last day of the model calibration period. Finally, we showed that the predicted articulatory precision scores mapped onto ALSFRS-R speech subscores. Results: the mean absolute error was as low as 4% for articulatory precision and 14% for ALSFRS-R speech subscores relative to the total range of their respective scales. Conclusion: Our results demonstrated that a subject-specific prognostic model for speech predicts future articulatory precision and ALSFRS-R speech values accurately.\n\nID: 36573040\nTitle: Maximum lingual pressure impacts both swallowing safety and efficiency in individuals with amyotrophic lateral sclerosis.\nAbstract: Although reduced lingual strength is a confirmed early manifestation of amyotrophic lateral sclerosis (ALS), its functional impact on swallowing remains unclear. We therefore sought to examine relationships between maximum anterior isometric lingual pressure (MAIP) with swallowing safety, swallowing efficiency, and swallowing timing metrics in a large cohort of individuals with ALS. Ninety-seven participants with ALS completed a standardized videofluoroscopic swallowing examination (VF) and lingual pressure testing (Iowa Oral Performance Instrument). Duplicate and blinded ratings of the Penetration-Aspiration Scale (PAS) and Analysis of Swallowing Physiology: Events, Kinematics and Timing (ASPEKT) percent efficiency (%C2-C42 ) and timing (laryngeal vestibule closure (LVC) duration: amount of time (milliseconds, msec) between LVC onset and laryngeal vestibule opening; time-to-LVC: hyoid burst to onset of LVC (msec); and swallow reaction time: interval between bolus passing ramus of mandible and onset of LVC (msec)) were performed across bolus trials. Swallowing safety (safe PAS: 1, 2, 4; unsafe PAS: 3, 5, 6, 7, and 8) and efficiency (inefficient: \u22653% worst total residue) were derived. Statistical analyses including descriptives, binary logistic regressions, and Spearman's rho correlations were performed (\u03b1\u00a0=\u00a00.05). Mean MAIP was 36.3\u00a0kPa (SD: 18.7). Mean MAIP was higher in those with safe swallowing as compared to those who penetrated (mean difference: 12\u2009kPa) or aspirated (mean difference: 18\u2009kPa). Individuals with efficient swallowing demonstrated higher MAIP than those with inefficient swallowing (mean difference: 11\u2009kPa). Binary logistic regression analyses revealed increasing MAIP was significantly associated with a 1.06 (95% CI: 1.03-1.09) and 1.04 (95% CI: 1.01-1.06) greater odds of safe and efficient swallowing, respectively. No relationships were observed between MAIP and swallow reaction time across all bolus trials. Longer time-to-LVC (5\u00a0ml thin liquid: rs \u00a0=\u00a0-0.35, p\u00a0=\u00a00.002; cup sip thin liquid: rs \u00a0=\u00a0-0.26, p\u00a0=\u00a00.02; moderately thick liquid: rs \u00a0=\u00a0-0.28, p\u00a0=\u00a00.01) and prolonged LVC duration (cup sip thin liquid, rs \u00a0=\u00a0-0.34, p\u00a0=\u00a00.003) were associated with lower MAIP. Reduced lingual strength was confirmed in this group of 97 individuals with ALS that was associated with a diminished ability to effectively transport boluses and aide in laryngeal vestibule closure to prevent entry of material into the airway.\n\nID: 36549252\nTitle: Voiceprint and machine learning models for early detection of bulbar dysfunction in ALS.\nAbstract: Bulbar dysfunction is a term used in amyotrophic lateral sclerosis (ALS). It refers to motor neuron disability in the corticobulbar area of the brainstem which leads to a dysfunction of speech and swallowing. One of the earliest symptoms of bulbar dysfunction is voice deterioration characterized by grossly defective articulation, extremely slow laborious speech, marked hypernasality and severe harshness. Recently, research efforts have focused on voice analysis to capture this dysfunction. The main aim of this paper is to provide a new methodology to diagnose this dysfunction automatically at early stages of the disease, earlier than clinicians can do. The study focused on the creation of a voiceprint consisting of a pattern generated from the quasi-periodic components of a steady portion of the five Spanish vowels and the computation of the five principal and independent components of this pattern. Then, a set of statistically significant features was obtained using multivariate analysis of variance and the outcomes of the most common supervised classification models were obtained. The best model (random forest) obtained an accuracy, sensitivity and specificity of 88.3%, 85.0% and 95.0% respectively when classifying bulbar vs. control participants but the results worsened when classifying bulbar vs. no-bulbar patients (accuracy, sensitivity and specificity of 78.7%, 80.0% and 77.5% respectively for support vector machines). Due to the great uncertainty found in the annotated corpus of the ALS patients without bulbar involvement, we used a safe semi-supervised support vector machine to relabel the ALS participants diagnosed without bulbar involvement as bulbar and no-bulbar. The performance of the results obtained increased, especially when classifying bulbar and no-bulbar patients obtaining an accuracy, sensitivity and specificity of 91.0%, 83.3% and 100.0% respectively for support vector machines. This demonstrates that our model can improve the diagnosis of bulbar dysfunction compared not only with clinicians, but also the methods published to date. The results obtained demonstrate the efficiency and applicability of the methodology presented in this paper. It may lead to the development of a cheap and easy-to-use tool to identify this dysfunction in early stages of the disease and monitor progress.\n\nID: 42420060\nTitle: Development of a target product profile for artificial intelligence in diabetic eye screening in England: a modified Delphi consensus study.\nAbstract: Artificial intelligence (AI) health-care technologies offer a means of addressing the growing gap between health-care capacity and demand. However, few technologies have met the complex requirements of health-care systems for adoption. Diabetic eye screening (DES) in England exemplifies the difficulty of understanding these requirements and translating them into real-world implementation decisions. This Review responds to a recognised policy need to develop a target product profile (TPP) for a DES AI system for use in England. The TPP outlines the requirements of the English health-care system for such a device and was developed using a modified Delphi consensus process involving interviews, surveys, and a consensus meeting. Participants included people living with diabetes, health-care professionals, health-care managers and leaders, regulators and policy makers, and developers. Thirty-five product specifications were agreed upon, covering areas such as clinical validity, utility, and environmental sustainability. Our TPP establishes clear criteria for DES AI development and deployment in England, and this TPP development process can serve as a template for initiatives to create TPPs for other AI health technologies and settings.\n\nID: 42414029\nTitle: Case of concurrent ALS and human T-cell leukaemia virus type 1-associated myositis.\nAbstract: A woman in her late 70s presented with progressive limb weakness, muscle atrophy and hyper-reflexia. Laboratory findings revealed elevated creatine kinase and positive serum human T-cell leukaemia virus type 1 (HTLV-1) antibody. Clinical and electrophysiological findings met revised El Escorial criteria for amyotrophic lateral sclerosis (ALS), but muscle MRI showed inflammatory changes. Muscle biopsy revealed both neurogenic and inflammatory features. While methylprednisolone showed no benefit, intravenous immunoglobulin therapy produced transient improvement in weakness with normalisation of creatine kinase levels. The patient died from respiratory failure 3 years after symptom onset. Autopsy confirmed typical ALS-TDP pathology with phosphorylated TDP-43 inclusions in motor neurons. HTLV-1 Tax-positive lymphocytes infiltrated skeletal muscles but not the central nervous system, establishing dual pathology of ALS-TDP with HTLV-1-associated myositis. The improvement most likely reflected treatment of the HTLV-1-associated myositis rather than the underlying motor neuron disease. This case highlights the importance of evaluating treatable conditions in HTLV-1-seropositive ALS patients.\n\nID: 42404161\nTitle: Perspective and quality of life in amyotrophic lateral sclerosis patients undergoing percutaneous endoscopic gastrostomy.\nAbstract: Percutaneous endoscopic gastrostomy (PEG) is commonly used to manage dysphagia and nutritional failure, which are among the most frequent and severe complications of amyotrophic lateral sclerosis (ALS). While several studies assessed PEG indications, outcomes, and prognostic factors, there is no evidence regarding ALS patients' perspectives and health-related quality of life (HRQoL) associated with PEG. This study included 48 consecutive ALS patients. At the 1-month follow-up after PEG, patients and their caregivers completed a PEG satisfaction questionnaire regarding their decision to proceed with the PEG-tube placement. HRQoL was assessed using the Gastrointestinal Quality of Life Index (GIQLI) and the Short Form-36 (SF-36). In total, 77.1% of patients and 88.9% of caregivers confirmed that they would prefer to have a PEG tube placed again if required (p\u202f>\u202f0.001); 93.8% of patients felt that PEG made feeding easier, exerting a positive effect on overall wellbeing (83.3%) and increasing survival rates (93.8%) (p\u202f>\u202f0.001); 54.2% felt that PEG was cosmetically acceptable. Consistent positive rates were reported by caregivers. The GIQLI digestion subscale values significantly improved from baseline (28.3; SD\u202f=\u202f6.6) to discharge (30.97, SD\u202f=\u202f5.84) and were maintained at 1-month follow-up (30.21, SD\u202f=\u202f6.7; p\u202f=\u202f0.014). Conversely, in follow-up assessments, we observed a significant reduction in the SF-36 physical component summary (PCS) subscale (baseline\u202f=\u202f33.3; 1-month follow-up\u202f=\u202f28.61; p\u202f=\u202f0.032), which was accompanied by a significant worsening in the GIQLI physical dimension subscale (baseline\u202f=\u202f9.63; 1-month follow-up\u202f=\u202f7.38; p\u202f=\u202f0.044). This study provides preliminary evidence that ALS patients have a positive perspective on PEG positioning, which may also have a beneficial effect on HRQoL related to gastrointestinal function.\n\nID: 42399082\nTitle: Radiologically inserted gastrostomy in advanced amyotrophic lateral sclerosis: clinical outcomes.\nAbstract: To evaluate survival and clinical outcomes in patients with amyotrophic lateral sclerosis (ALS) undergoing radiologically inserted gastrostomy (RIG) and to describe outcomes in patients in whom gastrostomy was indicated but not performed. This retrospective observational cohort study included patients with ALS followed by a multidisciplinary palliative care team between 2018 and 2020. Patients were classified according to gastrostomy status (RIG vs no RIG). Clinical data, respiratory support, nutritional status and survival outcomes were collected from medical records. Survival was analysed from gastrostomy indication using Kaplan-Meier curves stratified by baseline non-invasive ventilation (NIV) use. Among 155 patients with ALS, RIG was indicated in 53 and performed in 45; eight patients died before the procedure. 65 patients did not undergo gastrostomy. Median survival after RIG was 14.7 months, compared with 8 months in non-RIG patients who died. Baseline NIV use was associated with longer survival. No major safety concerns were identified. RIG appears to be a safe and feasible option in advanced ALS. Multidisciplinary care with integrated palliative involvement may facilitate referral, optimise nutritional support and support shared decision-making aligned with patients' goals of care. Further prospective studies are needed to confirm benefits and identify intervention timing.\n\nID: 42377311\nTitle: Could anticholinergics accelerate ALS progression? A critical perspective on drug safety and disease vulnerability.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder with limited treatment options and diverse symptoms necessitating active management. Anticholinergic medications are frequently used in ALS care, particularly for sialorrhea and mood disturbances. Their cumulative effects, termed anticholinergic burden, may pose underrecognized risks in this neurologically vulnerable population. This review highlights a plausible safety signal and outlines priorities for future research. This narrative review synthesizes evidence from non-ALS populations reporting associations between higher anticholinergic burden and cognitive decline, respiratory complications, functional deterioration, and mortality. Evidence was identified through targeted PubMed/MEDLINE and Embase searches with reference chaining, emphasizing recent and seminal studies. Mechanistic overlap with ALS pathophysiology, including neuromuscular junction disruption, impaired cholinergic signaling, and neuroinflammation, supports biological plausibility for harm. Current ALS guidelines do not address cumulative anticholinergic exposure, leaving clinicians without a framework for evaluating risk or deprescribing. This article proposes a testable hypothesis that anticholinergic burden may represent a clinically relevant yet unmeasured risk factor in ALS. Emerging pharmacoepidemiologic methods and validated burden tools offer approaches to quantify exposure and evaluate relationships with ALS outcomes, supporting safer symptomatic management. Prioritizing longitudinal studies and integrating burden assessment into multidisciplinary care may help clarify risk.\n\nID: 42366580\nTitle: At-Home Versus in-Clinic Vital Capacity Measurement: Insights From the HEALEY ALS Platform Trial.\nAbstract: Respiratory weakness, typically monitored as vital capacity (VC), is a central feature of amyotrophic lateral sclerosis (ALS). VC is increasingly measured remotely in participants' homes, although in-clinic assessment remains the standard. We tested concordance between at-home and in-clinic VC to determine trial eligibility, track progression, and predict survival in a large ALS trial. At-home and in-clinic VC were assessed at baseline and approximately every 8\u2009weeks for a year in the first four regimens of the HEALEY ALS Platform Trial. At-home assessments were coached via live videoconference and centrally reviewed. VC measurements, expressed as percent of predicted normal (%PN), were compared cross-sectionally, longitudinally, and for predicting survival time. Data from 233 participants with 3-8 paired at-home and in-clinic VC assessments completed <\u200914\u2009days apart were analyzed. At-home and in-clinic VC were well correlated (Lin's rc\u2009=\u20090.82) with no systematic bias. At-home VC \u2265\u200960%PN predicted in-clinic VC \u2265\u200960%PN with a positive predictive value of 91% and a negative predictive value of 65%. VC slopes were moderately correlated (rc\u2009=\u20090.68). At-home VC progressed 28% faster than in-clinic VC with proportionately less variance (at-home [SE]\u2009=\u2009-1.882 [0.153] %PN/month, in-clinic\u2009=\u2009-1.476 [0.131] %PN/month). Slopes of at-home and in-clinic VC explained 15% and 17% of variation in future survival time, respectively. At-home and in-clinic VC were well correlated cross-sectionally. At-home VC performed well tracking longitudinal change and predicting survival. The reduced participant burden of assessment and concordance with in-clinic measurement support use of at-home monitoring of VC.\n\nID: 42350385\nTitle: Intravenous administration of an engineered AAV9-gene-silencing vector suppresses human SOD1 and extends survival in an ALS mouse model.\nAbstract: Adeno-associated virus (AAV)-mediated gene silencing offers a promising strategy for achieving durable therapeutic effects with a single administration. Mutations in the human superoxide dismutase 1 (hSOD1) gene, inherited in an autosomal dominant manner, lead to motor neuron degeneration in amyotrophic lateral sclerosis (ALS)-a fatal neurodegenerative disease with no effective treatment. In this study, we employed AAV9 to deliver to the SOD1G93A ALS mouse model artificial microRNAs targeting SOD1, embedded in dual miR-33 scaffolds driven by the promoter of the human survival motor neuron 1 (hSMN1) gene. A single intravenous injection achieved widespread and sustained suppression of SOD1, preserved \u03b1-motor neurons, maintained neuromuscular junctions (NMJs), and improved muscle function. These benefits are translated into significantly improved respiratory function, motor performance, and survival. Therapeutic efficacy was observed both when the treatment was administered pre-symptomatically and during symptomatic stages. Compared with previous AAV-based interventions, the survival benefit achieved in this IV delivery approach is unprecedented, supporting its potential for clinical translation in SOD1-linked ALS and other central nervous system (CNS) diseases caused by gain-of-toxicity gene mutations.\n\nID: 42342266\nTitle: Cough biomarkers for diagnosis and monitoring of respiratory disease: a systematic review.\nAbstract: Cough is a common and physiologically informative component of respiratory morbidity, but its potential for diagnosing and monitoring disease is not thoroughly investigated. This systematic review synthesised the literature on algorithmic and statistical models analysing cough acoustics for diagnosing or monitoring respiratory conditions. Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, five databases (PubMed, Embase, Scopus, Web of Science and CENTRAL) were systematically searched for studies published from January 2010 to June 2025. Eligible studies performed quantitative acoustic feature analysis of human coughs using statistical, machine learning or deep learning models and reported diagnostic or prognostic performance. 89 studies from 34 countries were assessed, covering cough detection (n=31), disease classification (n=55) and disease severity prediction (n=3), reflecting potential applications in disease monitoring. Deep learning approaches, especially convolutional and recurrent networks, were predominant (n=56) and tended to achieve the higher accuracies, although machine learning ensemble methods and logistic regression also demonstrated strong performance, particularly with well-engineered features. Across different diseases, sensitivities and specificities were often reported to be \u226590%, notably for tuberculosis, asthma and COVID-19. However, methodological weaknesses were common, with only 11.2% of studies introducing external validation, 71.1-87.6% demonstrating high risk of bias (according to PROBAST-AI) and most based on small, homogeneous or crowdsourced cohorts with limited generalisability. These limitations contribute to inflated internal performance and uncertainty about real-world applicability. Cough acoustic biomarkers hold promise as an adjunctive tool for screening and longitudinal monitoring in low-resource environments. Nevertheless, widespread implementation will require large, multicentre validation, standardised calibration, bias control and incorporation into privacy-preserving workflows.\n\nID: 42339846\nTitle: Single-O2ligation of hemoglobin links aerobic and anaerobic metabolism.\nAbstract: Oxygen (O2) binding and release by hemoglobin (Hb) are governed by cooperative interactions among its four subunits. During incremental workload exercise, femoral venous oxyhemoglobin (O2Hb) saturation exhibits a reproducible, momentary increase at the gas exchange threshold-coinciding with the inflection point of the in vivo O2 non-equilibrium curve (ONC). This suggests a transient shift in Hb's binding dynamics. We hypothesized that at this threshold, Hb tetramers carrying \u22641 bound O2 become predominant. In this state, the last bound O2 promotes further cooperative binding, but its release confers no cooperative advantage for unloading, biasing toward O2 rebinding. Using the O2 equilibrium curve models of Dash et al. (2016) and Adair, we computed the distribution of Hb's O2 ligation states across 12 pooled mean femoral venous blood samples from incremental workload cardiopulmonary exercise testing of five healthy male participants. At the gas exchange threshold-where the ONC inflects and flattens-tetramers with \u22641 O2 indeed dominated. This ligation-state distribution is consistent with Perrella et al.'s (1999) cryogenic resolution of native human Hb, which shows that carbon monoxide-ligated Hb tetramers peak at ~15-20% saturation, matching femoral venous ranges at the gas exchange threshold. Our results suggest that, at sufficiently low O\u2082Hb saturation, Hb may favor O\u2082 rebinding over cooperative unloading. We propose that glycolytic proton production and other Bohr effectors may counter this predicted binding bias supporting continued O\u2082 unloading. If confirmed, this mechanism unifies long-standing controversies in O2 transport physiology, framing the Hb-Bohr system as a proportional-integral controller of tissue oxygenation.\n\nID: 42336241\nTitle: A multi-centre prospective evaluation of post-gastrostomy outcomes in patients with amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) often causes significant nutritional decline and weight loss, which negatively impacting prognosis. Gastrostomy is a standard intervention to provide long-term nutritional support, yet its efficacy in stabilising nutritional status and preventing post-procedure weight loss is uncertain. This study explored factors influencing weight change post-gastrostomy. This multicentre, prospective observational cohort study was conducted across 17 UK sites and involved longitudinal assessments at placement (M0) and at three (M3), six (M6), and nine (M9) months. Data collection included nutritional, clinical and functional parameters. The primary outcome was the percentage weight change between M0 and M3. Secondary outcomes included nutritional intake, functional decline, and survival. Statistical analysis employed hierarchical logistic regression to identify independent predictors of weight change post-gastrostomy. Successful gastrostomy was performed in 155 included participants, of which 64 had complete M0 and M3 weight data. Mean percentage weight change from M0 to M3 was -3.3% (SD 7.4%), with 51.6% losing >1 kg in the first three months (p<0.01). Amongst those with available dietary data weight loss (n=21/43) was associated with lower mean daily energy (1620 kcal vs 2022 kcal, p=0.017) and protein intake (64g vs 77g, p=0.048) compared to those who maintained stable or gained weight (n=22/43). At M3, 50% (n=29/58) used a combination of oral and gastrostomy intake, 27.6% (n=16/58) used gastrostomy only, and 22.4% (13/58) were not using the gastrostomy. Based on available data for total daily expenditure energy expenditure (TDEE) calculation (n=39), 61.5% did not meet predicted total daily energy expenditure. Participants who lost weight (>1kg) post-gastrostomy had shorter median survival (270 days) compared to the weight stable/gain group (p=0.018). Hierarchical logistic regression suggested that mean daily water intake may potentially be an independent predictor of weight maintenance or gain, though this finding should be considered exploratory due to the limitations of our study (OR=1.003, p=0.040). Despite gastrostomy placement, over half of participants in our final analytical cohort continued to lose weight. For a smaller subset of participants, for whom nutritional intake were available, this was potentially due to insufficient energy, macronutrient, and fluid intake, alongside disease-specific catabolism. As post-gastrostomy weight loss negatively impacts survival, these findings highlight a need for proactive, tailored, and ongoing nutritional support and monitoring, to optimise post-gastrostomy outcomes and survival in ALS.\n\nID: 42334216\nTitle: Tolerability, Safety and Effectiveness of Sigh Introduction During Non-Invasive Mechanical Ventilation Cycles in Patients With Amyotrophic Lateral Sclerosis.\nAbstract: Respiratory failure is the main cause of death in Amyotrophic lateral sclerosis (ALS), in which the physiological sigh reflex is impaired due to inspiratory muscle weakness. Aim of this study is to assess the tolerability, safety, and effectiveness of adding a sigh cycle to non-invasive mechanical ventilation (NIMV) settings in ALS patients. In this randomized, blind-controlled proof-of concept study, 44 consecutive ALS patients with indication for NIMV were randomized to: Group I: NIMV with Sigh cycles; Group II: NIMV without Sigh. The primary outcome was the reduction in the Oxygen Desaturation Index (ODI); secondary outcomes included: Overnight Oximetry (OvOx), Arterial blood gas (ABG), and Visual Analog Scale (VAS; 0-10) scores to assess sleep quality, symptom intensity, mask interface, and NIMV tolerance. Assessments were conducted at baseline, after NIMV adaptation (T1) and at 1-month follow-up (T2). The Sigh cycle was safe and well tolerated. No significant group differences were observed at T1 or T2 in the primary outcome ODI (median \u0394ODI: Group A:-4.2; Group B:-4.6: p\u2009=\u20090.54), as well as in the OvOx parameters and pO2 and pCO2 ABG values. At T2, secondary analysis showed a significant difference in HCO\u2083- in favor of the Sigh arm (\u0394HCO3 -: -1.60 vs. 1.35\u2009mmol/L, p\u2009=\u20090.042). Exploratory Cox-regression models suggested a potential independent effect of SIGH on survival. Sigh is safe, well tolerated in ALS patients. Although this study did not reach the primary outcome, we also cannot rule out that sigh doesn't benefit the patient.\n\nID: 42316902\nTitle: The ALS Home Health and Durable Medical Equipment Medical Standard Expert Consensus Guideline.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease associated with escalating disability and complex care needs. Although most individuals with ALS reside at home, existing US guidelines primarily address clinic-based care and provide limited direction on medically necessary home health services and durable medical equipment (DME). The objective of this task force was to develop expert consensus guidance defining minimum medical standards for home health services and DME for individuals with ALS, with the goal of improving patient outcomes, safety, and quality of life. This guideline was developed by a multidisciplinary task force convened by the American Association of Neuromuscular and Electrodiagnostic Medicine (AANEM). The process incorporated a scoping literature review, stakeholder engagement (patients, caregivers, and advocacy groups), and iterative expert consensus. Recommendations were informed by clinical expertise, patient-centered priorities, and existing policy frameworks. This guideline outlines stage-responsive home healthcare recommendations spanning nursing, home health aides, physical and occupational therapy, speech-language pathology, respiratory therapy, nutritional support, and social work. It emphasizes proactive, anticipatory care aligned with the predictable trajectory of ALS, rather than being reactive based on functional decline. The document defines medically necessary DME across domains, including mobility, communication, respiratory support, and activities of daily living, advocating for timely access independent of restrictive payer criteria. Key principles include coordinated interdisciplinary care, continuous reassessment, caregiver support, and integration of palliative care. These recommendations establish a foundational standard for ALS home-based care in the United States. Adoption may reduce delays, prevent complications, and support sustained independence and dignity for individuals with ALS.\n\nID: 42299015\nTitle: Amyotrophic Lateral Sclerosis: Therapeutic Innovations and Evolving Regulatory Approaches.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive degeneration of upper and lower motor neurons, leading to muscle weakness, paralysis, and respiratory failure. Despite extensive research, riluzole and edaravone remain the only globally approved disease-modifying therapies, offering modest survival benefits. This review summarizes current understanding of ALS pathogenesis, approved pharmacological treatments, and emerging gene-, RNA-, and cell-based therapeutic strategies. Particular emphasis is placed on regulatory considerations and evolving clinical trial designs in ALS drug development. The accelerated approval and subsequent withdrawal of sodium phenylbutyrate-taurursodiol (AMX0035) are discussed as a critical case study highlighting the challenges of regulatory flexibility in rare, fatal diseases. Advances in biomarker development, especially neurofilament light chain, are examined for their growing role in trial design and therapeutic evaluation. Collectively, these insights underscore a shift toward biomarker- informed and precision-based approaches that may improve future ALS therapeutic development.\n\nID: 42297981\nTitle: Plasma proteomic signatures of cellular aging predict human disease.\nAbstract: Aging is asynchronous across cells and organs. Here we tested whether plasma proteomics can be used to analyze cell type-specific aging. From analyses of over 7,000 plasma proteins measured in 60,542 individuals, we developed machine learning models to estimate the biological age of over 40 cell types spanning neuronal, immune, glial, endocrine, epithelial and musculoskeletal origins. We observed that 20-25% of individuals exhibited accelerated aging in a single cell type and 1-3% in 10 or more cell types. Cellular aging signatures were associated with disease status and predicted incident disease and mortality over 15 years of follow-up. Individuals with the APOE4 genotype showed older astrocytes but younger macrophages compared to APOE3 carriers, whereas the APOE2 genotype had inverse associations. Moreover, extreme astrocyte aging tripled the risk of incident Alzheimer's Disease in individuals with two APOE4 alleles, while youthful astrocytes reduced risk. Individuals with extremely aged compared to youthful skeletal myocytes exhibited a 12.7-fold higher risk of developing amyotrophic lateral sclerosis. In individuals who smoked, extreme respiratory epithelial cell aging was associated with a 58% higher lung cancer risk compared to smoking alone. Specific cellular vulnerabilities and cumulative cellular aging burden influenced survival, with youthful immune and neuronal cell types conferring protective effects. Finally, we developed a polycellular aging risk score that stratified mortality risk across cohorts and proteomics platforms. These findings establish a framework for quantifying human physiology at cellular resolution, revealing heterogeneous aging trajectories and their impact on disease susceptibility and resilience.\n\nID: 42261056\nTitle: The Flail Limb Syndrome.\nAbstract: The flail limb syndrome is primarily a lower motor neuron disorder that initially affects proximal arm muscles (flail arm syndrome-FAS) or distal leg muscles (flail leg syndrome-FLS). Both were recognized early on (1886 for FAS and 1918 for FLS) as somewhat distinct from classic amyotrophic lateral sclerosis (ALS). Descriptions in the literature are case series with limited information on electrophysiologic features (central and peripheral), cognitive involvement, and genetic mutations. What follows is a compilation of these features. The flail limb syndromes are rare, representing ~7%-8% of ALS. They have a higher ratio of males to females compared to classic ALS. Both are defined by predominant focal arm or leg weakness for ~2\u2009years before progression to other regions, although there can be early and mild clinical or electrophysiologic evidence for denervation and reinnervation in other regions during the initial period. Ultimately, there is progression to respiratory failure, but at a slower rate compared to classic ALS. Upper motor neuron clinical signs are variable, but transcortical magnetic stimulation paradigms and magnetic resonance imaging tractography support upper motor neuron loss. Tests of the split hand pattern show it is rare compared to ALS. Dementia is also rare. Genetic testing supports a spectrum of ALS-related gene mutations but at a lower frequency than with classic ALS, and no gene mutation is predominant. Diagnosis requires ~2\u2009years of regional stability to predict the better prognosis for the flail limb syndromes.\n\nID: 42259179\nTitle: Association of anti-glycolipid IgG with respiratory function decline in amyotrophic lateral sclerosis.\nAbstract: Effective treatments for amyotrophic lateral sclerosis (ALS) remain limited, underscoring the need to identify robust biomarkers associated with disease severity and prognosis. This study investigated whether immunoglobulin G (IgG) and immunoglobulin M (IgM) anti-glycolipid antibodies are associated with clinical manifestations of ALS, particularly decline in respiratory function. This was a retrospective observational cohort study of the patients with ALS. Among patients with definite or probable limb-onset ALS, 11 patients in the glycolipid IgG-positive group were compared with 15 patients in the IgG-negative group, and 5 patients in the glycolipid IgM-positive group were compared with 9 patients in the IgM-negative group, with adjustment for age. Associations between anti-glycolipid antibody status and respiratory function were assessed using Kaplan-Meier survival analysis and Cox proportional hazards models. The time to decline of percent forced vital capacity (%FVC) below 80% and 60% was significantly shorter in the IgG-positive group than in the IgG-negative group (p\u00a0=\u00a00.002 and p\u00a0=\u00a00.025, respectively). Cox proportional hazards analysis demonstrated that IgG antibody positivity was an independent risk factor for earlier decline in %FVC to 80%. These findings suggest that anti-glycolipid IgG antibodies may be associated with respiratory function decline in ALS. Larger comprehensive studies will be required to validate these results and to elucidate the underlying pathophysiological mechanisms.\n\nID: 42257902\nTitle: Early respiratory decline around diagnosis and short-term post-landmark outcomes in amyotrophic lateral sclerosis: a 6-month landmark cohort study.\nAbstract: In amyotrophic lateral sclerosis (ALS), respiratory decisions rely on serial trends rather than a single value. We evaluated whether early respiratory decline around diagnosis provides prognostic information in a real-world landmark framework. This single-center retrospective cohort screened 94 consecutive patients diagnosed between April 2019 and December 2025. A 6-month landmark was used. Early decline was estimated from %FVC values between -\u200930 and +\u2009180 days around diagnosis. The primary model included age and early %FVC decline; robustness analyses included time-varying Cox, piecewise Cox, RMST, included-vs-excluded comparison, death-only analysis, and slope-quality filtering. Of 94 screened patients, 62 met baseline eligibility, 56 had calculable early slope, and 45 entered the landmark cohort; 28 post-landmark composite events occurred. In the Cox model, faster early %FVC decline was associated with higher hazard of death or invasive mechanical ventilation via tracheostomy (HR 1.33 per 1%/month faster decline, 95% CI 1.14-1.55, p\u2009<\u20090.001). PH diagnostics suggested non-proportionality (%FVC p\u2009=\u20090.031; NIV p\u2009=\u20090.034 in the expanded model), so this HR was interpreted as an average follow-up association and complemented by PH-robust analyses. The signal was stronger early than late, remained consistent in a death-only analysis, and favored the slower-decline group by RMST at 24 and 36 months. In this selected measurement-capable landmark cohort, early respiratory decline provided a clinically meaningful short-to-medium term prognostic signal for post-landmark adverse outcomes. External validation is required before broader generalization beyond measurement-capable landmark populations.\n\nID: 42252883\nTitle: Telemonitoring associated with synchronous video consultation in patients on home mechanical ventilation: is it an efficient and effective intervention?\nAbstract: Telemonitoring combined with synchronous video consultation is an increasingly used strat-egy in the management of patients on home mechanical ventilation (HMV). The aim of this study was to evaluate ventilation parameters and healthcare resource utilization in a tele-monitoring program (TG) compared to usual care (UG). A retrospective comparative study was conducted, comparing HMV patients assigned to telematic follow-up with a historical cohort receiving standard in-person follow-up. Ventilation parameters included apnea-hypopnea index (AHI), average daily use (h/day), and mean leak (L/min). Efficiency was as-sessed by the total number of hospital visits and in-person hospital visits. Average daily use (8.3\u00b12.9 h/day vs. 8.5\u00b13.4 h/day; p=0.714) and mean leak (6.4\u00b111.9 L/min vs. 6.3\u00b19.6 L/min; p=0.701) did not differ significantly between groups. The TG showed a lower AHI compared with the UG [4.1\u00b15.0/hour vs. 7.9\u00b112.2/hour; respectively (p=0.008)]. The TG was also associated with fewer annual total visits (3.5\u00b12.4 vs. 6.9\u00b15.0; p<0.001) and fewer annual in-person visits (2.1\u00b11.6 vs. 6.9\u00b15.0; p<0.001). Kaplan-Meier curves were used for descriptive purposes. In multivariable Cox regression adjusted for age category, diagnostic group, baseline arterial blood carbon dioxide pressure, and sex, the TG was associated with a lower hazard of death (0.51; 95% confidence interval 0.24-1.09; p=0.08). These findings indicate that telemonitoring combined with synchronous video consultation was associated with better ventilatory control (lower AHI) and lower use of in-person healthcare visits, with-out evidence of impaired adherence or safety.\n\nID: 42229499\nTitle: Global burden of enteric infectious diseases, diarrhoeal diseases, and corresponding aetiologies, 1990-2023: a systematic analysis for the Global Burden of Disease Study 2023.\nAbstract: Enteric infectious diseases claim more than 1 million lives annually and are among the top ten causes of death in children younger than 5 years. Remarkable global investment has been dedicated to enteric infectious disease prevention and control; however, the shifting global health landscape is testing the continuance of progress. To evaluate the current status and guide future interventions, we present the latest epidemiological estimates of enteric infectious diseases from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023 and assess progress towards the Global Action Plan for the Prevention and Control of Pneumonia and Diarrhoea (GAPPD) mortality target of fewer than 20 deaths per 100\u2008000 children younger than 5 years by 2025. We quantified the incidence, mortality, and disability-adjusted life-years (DALYs) of enteric infectious diseases by age, sex, and year across 204 countries and territories from 1990 to 2023. In GBD 2023, the following were considered under the category of enteric infectious diseases: diarrhoeal diseases, enteric fever (typhoid and paratyphoid), invasive non-typhoidal Salmonella spp (iNTS) infections, and other intestinal infectious diseases. We also examined 15 aetiologies contributing to diarrhoeal diseases. Incidence and prevalence were estimated with DisMod-MR (version 2.1), a Bayesian meta-regression tool, drawing on data from systematic reviews, population-based surveys, claims data, and hospital sources. Cause-specific mortality was modelled with Cause of Death Ensemble Modelling based on data from sources including vital registration, mortality surveillance, verbal autopsy, and minimally invasive tissue sampling. Years of life lost and years lived with disability were computed and combined to derive DALYs. For aetiology-specific estimation, population-attributable fractions (PAFs) for 15 pathogens were derived with a counterfactual framework. Point estimates and 95% uncertainty intervals (UIs) were generated from 250 draws from the posterior distribution. In 2023, enteric infectious diseases resulted in an estimated 1\u00b727 million (95% UI 0\u00b7963-1\u00b768) deaths globally, declining from 3\u00b769 million (3\u00b704-4\u00b756) in 1990. The global age-standardised mortality rate (ASMR) decreased from 74\u00b71 (62\u00b70-92\u00b79) per 100\u2008000 population to 16\u00b74 (12\u00b76-21\u00b73) per 100\u2008000 population during the same period. Diarrhoeal diseases accounted for most deaths in 2023 (1\u00b711 million [0\u00b7811-1\u00b754]), followed by enteric fever and iNTS. South Asia and sub-Saharan Africa remained the most affected regions in 2023, with 599\u2008000 (441\u2008000-882\u2008000) and 501\u2008000 (373\u2008000-648\u2008000) deaths due to enteric infectious diseases, respectively, predominantly from diarrhoeal disease. Rotavirus was the leading cause of all-age diarrhoeal disease deaths (PAF 16\u00b73% [12\u00b70-21\u00b75]), followed by norovirus (10\u00b72% [2\u00b74-17\u00b70]) and Shigella spp (9\u00b73% [5\u00b74-15\u00b72]). Among children younger than 5 years, PAFs of deaths due to diarrhoeal diseases were 40\u00b72% (32\u00b75-48\u00b75) for rotavirus, 24\u00b70% (15\u00b71-36\u00b77) for Shigella spp, and 23\u00b74% (13\u00b77-34\u00b73) for adenovirus. Across 204 countries and territories, 141 met the GAPPD mortality target in 2023. The driving aetiologies among countries that did not meet the target in 2023 varied slightly by GBD super-region, but the highest or second-highest number of deaths in children younger than 5 years were consistently attributed to rotavirus. Astrovirus and sapovirus, newly included in GBD 2023, were responsible for 24\u2008600 (6290-49\u2008000) and 18\u2008800 (4650-44\u2008400) deaths, respectively, in 2023, mainly in children younger than 5 years. Our findings show that mortality and ASMRs of enteric infectious diseases declined substantially between 1990 and 2023. This decline is consistent with the expansion of public health measures and broader socioeconomic development. However, the burden in 2023 remains considerably high, with the highest mortality concentrated in sub-Saharan Africa and south Asia. Considering that more than a quarter of all countries had yet to meet the GAPPD mortality target in 2023, sustained efforts are needed to address the persistent burden in affected countries and to adapt to the changing global health landscape.

The aim of this study was to analyse the content and quality of German-language information on sarcoidosis available on the internet. All German-language hits from the first 200 search results for \"sarcoidosis\" on Google, Yahoo, Bing, and YouTube were saved. Two independent investigators evaluated the content (content score with 25 items, 0-25 points) and quality (DISCERN score with 1-5 points, HONCode score with 0-8 points, JAMA score with 0-4 points). 128 websites and 12 videos were included. The median time since the last update was 36 and 9 months. The content score was 17 and 13 points, respectively. Quality was rated with a DISCERN score of 2.4 and 2.1 points, the JAMA score of the websites was 2 points, and the HONCode score of the videos was 4.2 points. Blogs achieved poorer results in terms of content (p=0.040) and DISCERN score (p=0.016), while the JAMA score was best for news/media (p=0.002). There were no differences for the videos. Although some German-language information on sarcoidosis found on the internet was adequate in terms of content, its quality was only moderate. It would be desirable to have a reliable and easily recognisable label for adequate information.

Due to the strong link between dysphagia, weight loss, and disease progression, this study investigates the relationship between body composition and clinical outcomes in ALS adults. This cross-sectional study involved 93 ALS adults (29 females, 64 males) from Imam Khomeini Hospital in Tehran, selected based on EI Escorial criteria. Researchers assessed body composition, functional abilities, and disease progression using ALSFRS-R, MRC scores, and DPR, analyzing associations through linear regression models with RStudio in conjunction with R software. In this study, significant differences were found between the third and first tertiles for various measures. Significant associations were observed between body composition and ALSFRS-R for MAC (\u03b2: 3.0; P\u2009=\u20090.006), with underweight and moderately active adults exhibiting notable differences. The MRC score was positively associated with FFM (\u03b2: 5.8; P\u2009=\u20090.002), SLM (\u03b2: 5.6; P\u2009=\u20090.002), SMM (\u03b2: 3.8; P\u2009=\u20090.001), MAC (\u03b2: 3.2; P\u2009=\u20090.002), ICW (\u03b2: 2.7; P\u2009=\u20090.002), and ECW (\u03b2: 1.5; P\u2009=\u20090.003), while underweight and low-to-moderate physical activity adults indicated inverse associations. For DPR, significant relationships were noted for weight (\u03b2: 4.5; 95% CI: 0.02, 9.3; P\u2009=\u20090.002) and FFM (\u03b2: 11; P\u2009<\u20090.001), influenced by gender and physical activity. The findings highlight the role of gender, weight, and activity in ALS management, suggesting that maintaining a healthy weight along and muscle mass along with regular activity is associated with better outcomes. This can inform personalized treatment strategies for better patient care.\n\nID: 42214007\nTitle: Sleep disturbances and respiratory dysfunction in amyotrophic lateral sclerosis.\nAbstract: To investigate how respiratory dysfunction and site of onset influences changes in sleep architecture in people with ALS (pwALS). We conducted a retrospective observational study, analyzing demographic data, lung function tests, and polysomnography (PSG) measures. Descriptive statistics, correlation analyses, and survival analyses were performed. Our cohort had 240 pwALS, 63% male, median age at onset 59.3 (IQR 16.5) years. Median time from onset to PSG was 27.5 (IQR 25) months. Most pwALS had spinal onset (79%). Spirometry at time of PSG showed a reduced Forced Vital Capacity (FVC) (58; (IQR 26) %). We saw a significant FVC decline (3.9; (IQR 4) % per month) in the months before PSG. The sleep quality assessment in pwALS revealed a reduced total sleep time (339; (IQR 144.7) minutes), diminished sleep efficiency (62.8; (IQR 26.5)%) and increased wake after sleep onset (172; (IQR 130.2) minutes) when compared to normal values of healthy age-matched adults. The spinal onset group had a higher number of arousals. In the multivariate linear regression model adjusted for age and sex, FVC is a significant predictor for sleep efficiency (\u03b2\u2009=\u20093.359, p\u2009=\u20090.0059). Spinal onset, a slower rate of FVC decline in the months preceding PSG and a preserved FVC (\u2265 70%) at the time of PSG were associated with improved survival. We observed substantial sleep disturbances in our cohort overall with substantially increased arousals in the spinal group. FVC is a significant predictor for sleep efficiency and the decline in FVC is linked to survival.\n\nID: 42207242\nTitle: Anchoring ALS Prognosis: Neurofilament Light Chain Outperforms Inflammatory, Metabolic, and CNS Barrier Biomarkers in the METABALS Cohort.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a rapidly progressive and fatal neurodegenerative disorder with marked biological heterogeneity. Despite extensive research, reliable prognostic biomarkers remain limited, with neurofilament light chain (NfL) being the only marker increasingly implemented in clinical practice. The objective of this study is to assess and compare the prognostic value of NfL, circulating markers of central nervous system (CNS) barrier dysfunction, inflammatory mediators, kynurenine pathway metabolites, and global metabolomic profiles in patients with ALS. Seventy-two patients with ALS from the prospective multicenter METABALS cohort were included. Serum, cerebrospinal fluid (CSF), and urine samples were collected at diagnosis. NfL concentrations, markers of blood-brain and blood-spinal cord barrier permeability (albumin quotient, S100B, neuron-specific enolase [NSE]), 48 inflammatory mediators, kynurenine pathway metabolites, and untargeted metabolomic profiles were measured. Associations with clinical features, disease progression, and survival were investigated using univariate analyses and multivariate models. Serum and CSF NfL concentrations were strongly associated with ALS Functional Rating Scale-Revised scores, respiratory function, diagnostic delay, and survival. Higher serum NfL concentrations at diagnosis predicted shorter survival (ROC AUC\u2009=\u20090.86). In all multivariate and multi-block models, serum NfL was the only biomarker independently associated with survival. Markers of CNS barrier integrity, inflammatory mediators, and metabolomic signatures showed limited prognostic value but provided insights into metabolic remodeling and barrier dysfunction. In this integrated multi-omics study, serum NfL clearly outperformed inflammatory, metabolic, and CNS barrier markers as a prognostic biomarker in ALS, supporting its central role in clinical stratification while complementary biological markers highlighted several relevant pathophysiological mechanisms.\n\nID: 42191932\nTitle: Motor neuron disease in Africa: a critical appraisal of the literature.\nAbstract: Motor neuron disease (MND) refers to a group of neurodegenerative diseases that cause motor neuron degeneration and death. The most common subtype, amyotrophic lateral sclerosis (ALS), is characterized by both upper and lower motor neuron impairment, which can manifest clinically in the bulbar region or asymmetrically in a limb. Typically, the disease progresses over several months, and death from respiratory failure occurs within 2-5\u2009years of onset. As we highlight in this Review, data on MND in Africa are sparse, although common observations in this region - and in other populations with relatively low life expectancy - include apparent earlier disease onset and lower disease incidence compared with the rest of the world. In\u00a0view of the HIV epidemic in Africa, we critically examine the evidence for an association between ALS and HIV infection. We briefly discuss conditions that might be regarded as ALS mimics and summarize the limited data on MND genetics in this region. Other issues pertinent to people living with MND in Africa include the absence of cognitive and behavioural data and the limited access to multidisciplinary clinics, therapies and palliative care. We share our perspective on how the ALS Africa Network is coordinating a shift in the African MND landscape to improve patient care.\n\nID: 42191846\nTitle: The role of adiponectin and cytokines in Amyotrophic lateral sclerosis: assessment of disease progression and survival status.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal, progressive neurodegenerative disorder. ALS typically progresses rapidly, leading to respiratory failure within 3 to 5 years of symptom onset. Identifying risk factors that influence disease progression and survival is critical for enhancing management strategies. The present study therefore investigated the roles of inflammatory factors and adipokines (especially adiponectin) in the progression and prognosis of ALS.\u00a0The study included 80 ALS patients, with a follow-up period of 1.5 years. Survival analysis was performed using a Cox regression, with hazard ratios (HR) and 95% confidence intervals (CI) presented via forest plots. Our results indicated that ALS patients in the fast-progressing group exhibited lower levels of adiponectin (p\u2009<\u20090.001) and IL-10 (p\u2009<\u20090.001). The Cox regression and forest plot results suggest the potential of adiponectin (HR\u2009=\u20090.905, 95%CI: 0.866-0.946, p\u2009<\u20090.001), IL-10 (HR\u2009=\u20090.968, 95%CI: 0.951-0.986, p\u2009<\u20090.001), \u03b4FS (HR\u2009=\u20091.234, 95%CI: 1.065-1.430, p\u2009=\u20090.005) and ALSFRS-R (HR\u2009=\u20090.820, 95%CI: 0.765-0.878, p\u2009<\u20090.001) as potential risk factors. In addition, these risk factors are significantly associated with poor survival prognosis in high-risk populations (all p\u2009<\u20090.001). This study identifies adiponectin, IL-10, ALSFRS-R, and \u03b4FS as key risk factors influencing ALS progression and prognosis.\n\nID: 42187452\nTitle: Assessment of Respiratory Rate and Simulated Apnea Utilizing the PneumoWave Biosensor: In Vitro and In Vivo Validation.\nAbstract: Accurate monitoring of respiratory rates is critical for early detection of a range of clinical conditions. However, standard manual counting or inadequate clinical monitoring often fails to provide reliable measurements. This study evaluated and validated the PneumoWave biosensor for respiratory rate measurement across a broad physiological range and different body postures (45\u00b0, 90\u00b0, and 180\u00b0) in both in vitro and in vivo settings. In vitro validation was performed using a SimMan ALS manikin operated at respiratory settings of 6-30 breaths per minute, with 10 s periods of simulated apnea. In vivo validation involved 20 healthy volunteers performing metronome-guided breathing while wearing bilateral PneumoWave biosensors. In vitro results demonstrated an excellent correlation between biosensors and manikin respiratory settings and captured all apnea events (r = 0.99, ICC = 0.99). In vivo findings showed good agreement with direct observational count (r = 0.99, R2 = 0.99, ICC = 0.99), with 97% of apnea events captured by both devices in all positions. Body postures had no significant impact on biosensor accuracy. These findings demonstrate that the PneumoWave biosensor provides accurate and reliable respiratory monitoring and supports its potential as a robust, non-invasive tool for continuous clinical and remote patient monitoring.\n\nID: 42168009\nTitle: Primary Lateral Sclerosis French National Diagnostic and Care Protocol.\nAbstract: Primary lateral sclerosis (PLS) is a rare neurodegenerative motor neuron disease characterized by progressive and selective involvement of the central motor neuron within the bulbar and spinal regions. It is estimated to account for 1-5% of motor neuron diseases and typically presents in the fifth or sixth decade of life, with a slight male predominance. According to current consensus criteria, the diagnosis relies on the demonstration of progressive upper motor neuron dysfunction in the absence of lower motor neuron involvement, with persistence of isolated upper motor neuron signs for at least four years in order to exclude a slowly progressive upper motor neuron-predominant form of amyotrophic lateral sclerosis (ALS). The French Motor Neuron Disease Network (FILSLAN) developed a National Diagnostic and Care Protocol (PNDS) with the aim of standardizing diagnostic criteria, optimizing differential diagnosis, and providing evidence-based recommendations for therapeutic management and follow-up across the national territory. These recommendations were elaborated in accordance with the methodological framework of the French National Authority for Health for rare diseases. The protocol provides practical guidance for establishing PLS as a diagnosis of exclusion, distinguishing it from ALS and hereditary spastic paraplegias, and organizing appropriate clinical and paraclinical investigations. It also outlines indications for genetic testing in selected cases and defines a multidisciplinary management strategy centered on symptomatic treatment, early rehabilitation, respiratory and nutritional surveillance, and psychosocial support. Given the slower progression of PLS compared with ALS, biannual multidisciplinary follow-up is generally appropriate. This protocol aims to harmonize clinical practice and improve patient care while acknowledging the current absence of disease-modifying therapies.\n\nID: 42251620\nTitle: Tongue volume in spinal and bulbar muscular atrophy (SBMA): an AI-assisted automatic MRI analysis.\nAbstract: Atrophy of the tongue muscle without severe dysarthria is one of the clinical hallmarks of spinal and bulbar muscular atrophy (SBMA), a motor neuron disease caused by an androgene receptor defect. An operator-independent AI-based automatic segmentation of the tongue was applied to 3-D MRI data of the head in SBMA in order to quantify the tongue atrophy. Thirty-nine patients with SBMA and 51 age-matched healthy controls underwent MRI which were used for tongue volume quantification. A single triplanar convolutional neural network of U-Net architecture trained on axial, coronal, and sagittal planes was used for the segmentation of the tongue in MRI scans of the head, the resulting volumes were processed slice-wise across the three orientations and corrected for age. At the group level, a significant atrophy of the tongue was observed in SBMA when compared to controls (p\u2009<\u20090.05). Atrophy correlated well with total SBMA-functional rating scale and even more with bulbar subscores. In summary, the study employed an AI-assisted advanced imaging analysis to quantify the tongue morphology in individuals with SBMA in correlation to clinical bulbar function, suggesting this approach as a potential biomarker for disease assessment.\n\nID: 42225765\nTitle: Longitudinal cognitive assessment using the Cumulus NeuLogiq platform in amyotrophic lateral sclerosis and frontotemporal dementia.\nAbstract: People living with ALS (plwALS) and/or FTD (plwFTD) often experience cognitive and behavioural changes. However, detection can be confounded due to factors like fatigue and testing anxiety. Cumulus neuroscience developed NeuLogiq(R), a multi-modal neurocognitive platform that can be used in clinic or at home, providing an ecologically valid measure of cognition. This study examined the feasibility and usability of NeuLogiq in plwALS, plwFTD, and controls, and compared performance on gold standard neuropsychological assessments with corresponding NeuLogiq digital assessments. Over 8 months, plwALS (n\u2009=\u200911), plwFTD (n\u2009=\u20097), and matched healthy controls (n\u2009=\u200910) completed longitudinal full neuropsychological assessment, as well as three 25-minute NeuLogiq Platform sessions every 2 weeks in their homes. Participants adhered well to the study schedule, conducting over 32/54 sessions on average. All groups rated usability in the 'good' or 'excellent' range and had\u2009>\u200980% complete data. Baseline group differences were detectable on both NeuLogiq digital assessments and benchmark neuropsychological assessments of similar cognitive domains. Longitudinal mixed effects models found that the ALS group showed decline on NeuLogiq measures of emotion recognition and speech fluency. These findings suggest that the NeuLogiq platform is feasible and usable for plwALS and plwFTD, and can identify cognitive deficits to a similar extent as benchmark assessments over time.\n\nID: 42091714\nTitle: The Dysphagia Outcome and Severity Scale (DOSS) and non-instrumental swallowing measures in amyotrophic lateral sclerosis.\nAbstract: To evaluate reliability of the Dysphagia Outcome and Severity Scale (DOSS) in Amyotrophic Lateral Sclerosis (ALS) patients, and to assess diagnostic accuracy of selected non-instrumental measures in defining swallowing safety in this population. One hundred and thirteen consecutive ALS patients underwent comprehensive dysphagia evaluation with fiberoptic endoscopic evaluation of swallowing (FEES) and were classified according to DOSS. Safe and unsafe swallowing were defined by DOSS levels 7-6 and 5-1, respectively. Patient-reported measures included ALS Functional Rating Scale-Revised swallow item (I-3) and Eating Assessment Tool-10 (EAT-10). Non-instrumental clinical measures were hyolaryngeal excursion, voluntary cough (VC), voice quality and reflexive cough/throat clearing (VRC), and maximum phonation time (MPT). Inter- and intra-rater reliability were assessed using weighted Cohen's kappa and Fleiss' kappa coefficients. Non-instrumental measures diagnostic performance was evaluated using receiver operating characteristic (ROC) curve analysis. Twenty-six of 113 patients (23%) exhibited an unsafe swallowing. Inter- and intra-rater agreement for DOSS classification was excellent across raters. EAT-10 and a composite clinical index derived from VC, VRC, and MPT showed the highest diagnostic accuracy with area under the curve values of 0.790 and 0.832, respectively. Other non-instrumental measures demonstrated lower discriminative performance. The DOSS showed an excellent reliability when applied to FEES in patients with ALS, supporting its use as a functional classification tool with direct nutritional and management implications. Non-instrumental measures should be interpreted with caution and confined to a triage role rather than diagnostic decision-making, particularly in light of the rapid progression of dysphagia in ALS.\n\nID: 41872984\nTitle: Muscle MRI and Muscle Ultrasound Applications in MND/ALS: Academic Insights and Clinical Opportunities.\nAbstract: There is an unmet need for the clinically relevant ALS biomarkers to facilitate an accurate diagnosis in suspected cases, monitor disease progression and evaluate response to therapy in clinical trials. While the MND/ALS literature is dominated by innovative brain studies, motor disability in ALS is primarily driven by neurogenic muscle change impacting mobility, dexterity, respiratory and bulbar function. With the intention of raising awareness of muscle-derived imaging markers in ALS, a systematic review has been conducted. Study designs, imaging methods, data interpretation frameworks, and cohort characteristics were systematically evaluated to identify innovative approaches and barriers to clinical implementation. A total of 219 studies were screened and 73 original studies selected for systematic review; 37 muscle MRI studies and 36 studies using ultrasound, PET or CT. All of the selected studies successfully captured ALS-associated muscle degeneration and their methods included the evaluation of muscle dimensions (thickness/volumes n\u2009=\u200934), 'acute' denervation (water content, n\u2009=\u200915), fasciculation counts (n\u2009=\u200914), 'chronic' neurogenic change (fat content, n\u2009=\u200921), metabolic changes (n\u2009=\u20094), diffusion alterations (n\u2009=\u20098) and echo intensity changes (n\u2009=\u200913). Despite the huge impact of lower motor neuron dysfunction on the patients' independence, survival and quality of life, muscle imaging is a glaringly overlooked frontier of MND/ALS research. This is a missed opportunity, as a variety of non-invasive quantitative muscle imaging techniques have been successfully used in other neurological conditions; these protocols are easy to implement on commercial MRI and ultrasound platforms and recent studies have demonstrated their ease of use and potential clinical utility.\n\nID: 41406304\nTitle: Pridopidine treatment in ALS: subgroup analyses from the HEALEY ALS Platform trial.\nAbstract: Objectives: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with limited treatment options. Pridopidine, a selective sigma-1 receptor agonist, was evaluated in Regimen D of the HEALEY ALS Platform Trial. Although the primary endpoint (ALS Functional Rating Scale-Revised (ALSFRS-R) total score accounting for survival at 24\u00a0weeks) was not met, a predefined subgroup analysis suggested slowed disease progression in ALS patients with definite and early disease (<18\u00a0months from onset). This report presents an exploratory analysis that further investigates pridopidine in rapidly progressing participants with definite/probable ALS and early-disease, where treatment effects may be more pronounced. Methods: The randomized, double-blind, placebo-controlled phase 2 trial assigned participants to pridopidine 45\u2009mg bid or placebo, and placebo patients were shared across four trial regimens. The primary outcome was ALSFRS-R total score, with secondary outcomes assessing respiratory, bulbar, and speech functions. Results: Of 163 participants randomized to Regimen D, 72 met subgroup criteria (pridopidine: n\u00a0=\u00a037; shared placebo: n\u00a0=\u00a035). At week 24, pridopidine slowed ALSFRS-R total score decline (32%; \u03942.90, p\u00a0=\u00a00.03) and slowed decline of ALSFRS-R respiratory function (62%; \u03941.20, p\u00a0=\u00a00.03) and dyspnea (88%; \u03940.85, p\u00a0=\u00a00.005). ALSFRS-R-Bulbar function stabilized, with articulation and speaking rate declines reduced by 93% (\u03940.43, p\u00a0=\u00a00.0007) and 70% (\u03940.43, p\u00a0=\u00a00.002), respectively. Pridopidine was well-tolerated, with a safety profile comparable to placebo. All p values are nominal. Conclusion: Post hoc subgroup analysis suggests therapeutic benefits of pridopidine in patients that had definite/probable ALS and with early-disease progression, supporting further evaluation in a Phase 3 trial.\n\nID: 41267082\nTitle: Expanding research and care for Leigh syndrome: efforts of a patient-led advocacy organization.\nAbstract: BACKGROUND: Leigh syndrome is a rare, progressive neurometabolic disorder caused by pathogenic variants in over 110 mitochondrial or nuclear genes. Its clinical and genetic heterogeneity creates challenges for diagnosis, care, and research. Cure Mito Foundation, a parent-led nonprofit established in 2018 to develop a gene therapy for SURF1-related Leigh syndrome, has since evolved into a global organization supporting individuals and families worldwide affected by all forms of Leigh syndrome. METHODS: This article describes the multifaceted efforts of Cure Mito Foundation to accelerate research and support for Leigh syndrome through family-led engagement and collaborative scientific partnerships. Strategies include funding the development of diverse disease models, gene therapies, drug repurposing pipelines, and a global patient registry. Emphasis is placed on co-production with affected families, sharing of biospecimens and data, and alignment with regulatory and research standards. RESULTS: The Leigh Syndrome Global Patient Registry comprises over 400 participants from 48 countries, with data made available to qualified researchers, and results shared regularly with the patient community to promote transparency and trust. Notable research accomplishments of Cure Mito include facilitating the development of multiple gene therapy candidates, patient-derived organoids and animal models, and repurposed drugs now entering early-phase trials. Cure Mito also played a key role in the launch of the Mitochondrial and Inherited Metabolic Disease Taskforce, led by the Critical Path Institute (C-Path), to integrate registry and clinical data into the Rare Disease Cures Accelerator platform. Additional efforts include community-developed educational tools, international awareness campaigns, and support programs tailored to the unique needs of Leigh syndrome families. CONCLUSIONS: Through relentless effort and dedication, the Cure Mito Foundation has shown that a small group of determined individuals can drive extraordinary change. By building a global patient registry, advancing data sharing and research, developing patient-centric education and support, and facilitating collaboration among scientists, clinicians, and families, the Foundation has created momentum toward effective treatments. With support from the Chan Zuckerberg Initiative\u2019s Rare As One grant, Cure Mito is poised to expand its impact even further. Leigh syndrome is a severe genetic disorder that begins in early childhood and leads to the gradual loss of physical and developmental abilities. It can be caused by variations in over 110 different genes and can affect multiple organs and systems in the body. Cure Mito Foundation is a nonprofit organization founded by parents of children with Leigh syndrome. Since its inception in 2018, the Foundation has evolved into a global initiative to support children and families affected by this rare condition. This article highlights the Cure Mito Foundation\u2019s efforts to advance research and provide support to families. The Foundation partners with scientists to explore potential treatments, including gene therapy, drug repurposing, and mitochondrial genome editing. It also established a global patient registry to collect valuable data from families, enabling researchers to better understand Leigh syndrome. The latest registry findings are included in this report. Importantly, families are not only participants in research - they also help guide it. Cure Mito ensures that patient and caregiver voices influence decisions, promote knowledge sharing, and foster a sense of support and community. The Foundation also offers practical resources for healthcare providers, caregivers, and families, including educational videos, a family planning guide, and a directory of medical experts. Through international collaboration and a strong, engaged community, Cure Mito Foundation is accelerating progress toward better care and future cures.\n\nID: 40851280\nTitle: Automatically measured speech intelligibility models bulbar-specific disease severity and progression in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that leads to widespread motor deterioration, including significant motor speech impairments. Speech intelligibility is a crucial component of communication affected in ALS, requiring objective, scalable assessment methods as an indicator of disease progression and treatment efficacy. Objective: This study investigates whether speech and bulbar function in ALS could be evaluated and monitored utilizing an automated digital measure of speech intelligibility derived from naturalistic picture descriptions. Methods: Speech recordings from 44 patients living with ALS (plwALS) and 49 matched healthy controls (HC) were analyzed and processed utilizing an automated speech analysis pipeline to extract an intelligibility score. These were part of a cross-sectional and longitudinal study involving two assessments.\u00a0Results: The findings confirmed that speech intelligibility is significantly reduced in plwALS compared to HC. Those with bulbar-onset ALS have lower intelligibility than those with spinal-onset ALS, and the intelligibility of individuals with bulbar symptoms-regardless of the onset type-is lower than in plwALS without bulbar symptoms. Declining ALS-related speech scores correspond with worsening intelligibility in longitudinal assessments. Intelligibility correlates strongly with bulbar-specific clinical measures but not with global scores, highlighting its role in tracking bulbar progression. In some plwALS, we were able to demonstrate that automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring. Conclusion: Our findings highlight that automated speech intelligibility assessments can be a valuable marker to improve clinical monitoring and facilitate earlier intervention in ALS as a supplement to standard assessments.\n\nID: 40778350\nTitle: Safety and tolerability of onasemnogene abeparvovec for patients with spinal muscular atrophy weighing \u226417 kg and \u226424 months old from OFELIA, a phase 4, open-label, multicenter, non-randomised, interventional study.\nAbstract: OFELIA aimed to evaluate outcomes related to safety and motor milestones following administration of onasemnogene abeparvovec, a one-time gene replacement therapy, for patients with spinal muscular atrophy (SMA) from Latin America. OFELIA (NCT05073133) is a phase 4, 18-month, open-label, multicenter, non-randomised study (Brazil, Argentina) of onasemnogene abeparvovec treatment (1\u00b71 \u00d7 1014 vg/kg) for symptomatic patients with SMA \u226424 months of age and \u226417 kg (grouped by age [0-12 vs >12-24 months] and weight [<8\u00b75 kg vs \u22658\u00b75 kg]). The primary endpoint was safety. The secondary endpoint was demonstration of motor milestones measured at screening and at 6, 12, and 18 months post-onasemnogene abeparvovec infusion, according to the World Health Organization Multicentre Growth Reference Study criteria. Sixteen patients were enrolled (n = 11/16 female; n = 10/16 SMA type 1) (n = 17 screened). All reported adverse events (AEs). Eleven reported serious AEs; 12 reported an AE of special interest, most commonly hepatotoxicity (asymptomatic) (n = 11/12), thrombocytopenia (n = 5/12), and thrombotic microangiopathy (n = 2/12). Two deaths occurred: one possibly related to treatment (AST >20 \u00d7 upper limit of normal, sepsis, infection, multiorgan failure, thrombotic microangiopathy) and one due to respiratory infection. Most patients maintained/improved motor milestones up to 18 months post-onasemnogene abeparvovec (e.g., sitting, crawling, standing, walking), including those in the >12-24-month age group. Most common AEs of special interest were hepatotoxicity, thrombocytopenia, and thrombotic microangiopathy; incidence rates (hepatotoxicity, thrombocytopenia) were similar compared with studies in patients >6 months of age and >8\u00b75 kg. Efficacy data on demonstration of motor milestones suggest that Latin American patients with SMA may benefit from onasemnogene abeparvovec treatment. The study was funded by Novartis Pharma AG, Basel, Switzerland.\n\nID: 40527647\nTitle: The Association Between Bilingualism and Voice Quality in Spanish-English Bilingual Speakers: A Systematic Review.\nAbstract: The vast majority of the global population speaks more than one language. In the United States, Spanish-English bilingual speakers are the largest bilingual group. Yet, the potential effect of being bilingual, specifically a Spanish-English speaker, on voice quality is poorly understood. The current study consequently set out to systematically review the literature on the association between being a Spanish-English bilingual speaker and voice quality. Systematic review. A systematic review of association was conducted using Moola et al's guidelines. A search string was developed and run in May 2024 across three databases: MEDLINE (via PubMed), CINAHL via EBSCOhost, and Scopus. After duplicate removal, title, and abstract screening, full-text screening was performed, and peer-reviewed articles considering voice quality measures in Spanish-English bilingual speakers were included. Data were extracted and presented in table format, and the quality of the articles was assessed using the Checklist for Analytical Cross-Sectional Studies. In total, 685 records were retrieved, with 485 remaining after duplicate removal. After title and abstract screening, 25 full texts were screened, including 8 articles in the review. Five studies included acoustic measures describing voice quality, with only three including auditory-perceptual analysis. The most commonly considered vocal trait in Spanish-English bilinguals was vocal fry, with the included studies pointing to increased vocal fry use when speaking English. Only a few articles discuss potential vocal changes in Spanish-English bilinguals. Further research is needed to elucidate any potential vocal changes related to being a bilingual speaker, as the current small number of studies and mixed findings make drawing conclusions difficult. More standardization across voice and language assessment could be beneficial.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

These changes\u2014often subtle and requiring sophisticated extraction\u2014precede functional communicative decline and may provide a window for early diagnosis.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe clinical trajectory of Amyotrophic Lateral Sclerosis (ALS) is increasingly recognized to include a prolonged, clinically silent prodromal period. Quantitative analysis of vocal and speech motor control, utilizing surface electromyography (sEMG) and acoustic signal processing, identifies nuanced physiological patterns of decline\u2014specifically in phonatory stability, glottal tension, and articulatory precision\u2014that emerge before the manifestation of traditional clinical symptoms, offering a non-invasive, scalable biomarker for early detection.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic Lateral Sclerosis is traditionally viewed as a disorder of motor neuron degeneration characterized by progressive limb or bulbar weakness. However, emerging research into digital speech biomarkers indicates that bulbar involvement can be detected through non-invasive assessments during the prodromal phase. Current clinical standards, such as the ALS Functional Rating Scale-Revised (ALSFRS-R), lack the sensitivity to capture these subclinical neuromuscular changes. Digital voice analysis\u2014leveraging high-frequency acoustic data and biomechanical models of vocal fold vibration\u2014serves as a high-fidelity diagnostic instrument. The integration of artificial intelligence and machine learning pipelines allows for the automatic extraction of composite outcome measures that demonstrate clinical validity in differentiating ALS profiles from healthy aging and other neurodegenerative conditions. These metrics, such as articulatory rate, fundamental frequency variation, and glottal stability, act as objective markers of the underlying motor neuron pathology, potentially enabling earlier intervention and precision-based therapeutic monitoring.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Subclinical Detection:** Artificial intelligence frameworks can identify neuromuscular changes during the \"clinically silent prodromal stage\" before functional decline is apparent.\n*   **Biomechanical Precision:** Biomechanical voice parameters reflecting glottal tension and vocal fold stability are sensitive enough to differentiate clinical phenotypes (bulbar vs. spinal onset).\n*   **Multimodal Integration:** Combining facial sEMG and acoustic signals outperforms single-modality assessments in detecting early bulbar motor dysfunction.\n*   **Listener Effort (LE):** LE is a clinician-rated metric that captures meaningful change in dysarthria and shows potential as a responsive clinical trial endpoint.\n*   **Smartphone Utility:** Simple, smartphone-based assessment tasks (e.g., tongue lateralization or vowel phonation) correlate highly with laboratory-standard assessments, increasing access.\n*   **Stability of Biomarkers:** Despite disease progression, high-gamma cortical features in ECoG speech BCIs show long-term stability, suggesting durability for assistive interfaces.\n*   **Predictive Modeling:** Subject-specific prognostic models can now predict articulatory precision and ALSFRS-R speech subscores 30\u201390 days in advance.\n*   **Vocal Subtypes:** Unsupervised clustering reveals \"vocal profiles\" that transcend traditional diagnostic labels, indicating that voice features capture functional patterns of voice production across different disorders.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

In 25% of ALS sufferers, speech disorders occur as prodromal symptoms of the disease. Impaired communication affects physical health and has a negative impact on mental and emotional condition. In this study, we assessed which domains of speech are particularly affected in ALS. Subsequently, we estimated possible correlations between the ALS patients' subjective perception of their speech quality and an objective assessment of the speech organs carried out by an expert. The study group consisted of 63 patients with sporadic ALS. The patients were examined for articulatory functions by means of Voice Handicap Index (VHI) and the Frenchay Dysarthria Assessment (FDA). On the basis of the VHI scores, the entire cohort was divided into 2 groups: group I (40 subjects) with mild speech impairment, and group II (23 subjects) displaying moderate and profound speech deficits. In an early phase of ALS, changes were typically reported in the tongue, lips and soft palate. The FDA and VHI-based measurements revealed a high, positive correlation between the objective and subjective evaluation of articulation quality. Deterioration of the articulatory organs resulted in the reduction of social, physical and emotional functioning. The highly positive correlation between the VHI and FDA scales seems to indicate that the VHI questionnaire may be a reliable, self-contained tool for monitoring the course and progression of speech disorders in ALS.

This review provides a comprehensive overview of the current knowledge on the clinical manifestations, diagnostic differentiation, underlying mechanisms, diagnostic tools, and therapeutic strategies for the treatment of dysarthria in ALS. We update on the most promising digital speech biomarkers of ALS that are critical for early and differential diagnosis. Advances in artificial intelligence and digital speech processing have transformed the analysis of speech patterns, and offer the opportunity to start therapy early to improve vocal function, as speech rate appears to decline significantly before the diagnosis of ALS is confirmed. In addition, we discuss the impact of interventions that can improve vocal function and quality of life for patients, such as compensatory speech techniques, surgical options, improving lung function and respiratory muscle strength, and percutaneous dilated tracheostomy, possibly with adjunctive therapies to treat respiratory insufficiency, and finally assistive devices for alternative communication."

The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech\u2011derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1\u2011weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS."

Speech intelligibility is a crucial component of communication affected in ALS, requiring objective, scalable assessment methods as an indicator of disease progression and treatment efficacy. Objective: This study investigates whether speech and bulbar function in ALS could be evaluated and monitored utilizing an automated digital measure of speech intelligibility derived from naturalistic picture descriptions. Methods: Speech recordings from 44 patients living with ALS (plwALS) and 49 matched healthy controls (HC) were analyzed and processed utilizing an automated speech analysis pipeline to extract an intelligibility score. These were part of a cross-sectional and longitudinal study involving two assessments.\u00a0Results: The findings confirmed that speech intelligibility is significantly reduced in plwALS compared to HC. Those with bulbar-onset ALS have lower intelligibility than those with spinal-onset ALS, and the intelligibility of individuals with bulbar symptoms-regardless of the onset type-is lower than in plwALS without bulbar symptoms. Declining ALS-related speech scores correspond with worsening intelligibility in longitudinal assessments. Intelligibility correlates strongly with bulbar-specific clinical measures but not with global scores, highlighting its role in tracking bulbar progression. In some plwALS, we were able to demonstrate that automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring. Conclusion: Our findings highlight that automated speech intelligibility assessments can be a valuable marker to improve clinical monitoring and facilitate earlier intervention in ALS as a supplement to standard assessments."

Effective management of progressive communication disorders requires a personalized approach to deliver timely interventions tailored to the evolving profiles of communicative impairment, thereby supporting functional communication throughout the disease course. To this end, reliable tools capable of detecting and quantifying both disease-specific patterns of communicative impairment and within-disease phenotypic variability are urgently needed. This study leverages Artificial Intelligence and advanced data analytics to develop an acoustic-based framework for automated extraction of interpretable, clinically grounded speech markers to enable objective assessment and phenotyping of progressive communication disorders. Three groups of participants, including 14 individuals with amyotrophic lateral sclerosis (ALS) and 15 individuals with Parkinson's disease (PD), alongside 10 neurologically healthy controls, performed a standardized oral passage reading task, yielding 739 speech samples. Fifty acoustic features were extracted using an automated analytic pipeline and subsequently clustered into six interpretable composite markers. The clinical utility of these markers was evaluated with the recorded speech samples by examining their (1) associations with standardized metrics of cognitive, motor speech, and overall communicative functions, (2) efficacy for detecting and differentiating disease-specific communicative impairment patterns in ALS and PD using supervised machine learning, and (3) utility for within-disease phenotyping and stratification using unsupervised clustering analysis. The markers effectively (1) detected subtle subclinical changes across multiple domains prior to substantial declines in functional communication outcomes; (2) differentiated disease-specific patterns of communicative impairment (multiclass area under the curve > 0.90); and (3) identified subgroups with distinct speech profiles within each disease. The findings support the potential of the proposed framework as a clinically translatable, objective tool to facilitate early detection, differential diagnosis, and phenotyping of progressive communication disorders, ultimately advancing personalized, measurement-based care in neurodegenerative diseases."

Dysarthria, characterized by impaired speech production, is common in ALS and often correlates with disease severity. Voice analysis has emerged as a promising tool for detecting disease progression and monitoring functional status. Methods: This study investigates acoustic and biomechanical voice alterations in ALS patients and their association with clinical measures of functional independence. A descriptive observational case series study was conducted, involving 43 ALS patients and 43 age and sex matched controls with non-neurological voice disorders. Sustained vowel /a/ recordings were obtained and analyzed using Voice Clinical Systems\u00ae and Praat software (version 6.2.22). Biomechanical and acoustic parameters were correlated with ALS Functional Rating Scale-Revised (ALSFRS-R) and Barthel Index scores. Results: Significant differences were observed between ALS and control groups (elevated muscle force and tension and interedge distance in non-ALS individuals). Between bulbar and spinal ALS subtypes, elevated values were observed in certain parameters in Bulbar ALS patients, indicating irregular vocal fold contact and weakened phonatory control, while spinal ALS exhibited increased values, suggesting higher phonatory muscle tension. Elevated biomechanical parameters were significantly correlated with low ALSFRS-R scores, suggesting a possible relationship between voice measures and functional decline. However, acoustic measurements showed no relationship with performance status. Conclusions: These results highlight the potential of voice analysis as a non-invasive, objective tool for monitoring ALS stage and differentiating between subtypes. Further research is needed to validate these findings and explore their clinical applications."

We assess past, current, and emerging trends in the prevalence and burden of mental disorders across sexes and age groups, for 21 regions, 204 countries and territories, and by Socio-demographic Index (SDI) quintile, from 1990 to 2023. Mental disorders included in GBD 2023 were anxiety disorders, major depressive disorder, dysthymia, bipolar disorder, schizophrenia, autism spectrum disorders, conduct disorder, attention-deficit hyperactivity disorder, anorexia nervosa, bulimia nervosa, idiopathic developmental intellectual disability, and a residual category of other mental disorders. A literature review identified epidemiological data for each disorder. These were analysed via a Bayesian meta-regression to estimate prevalence by disorder, sex, age, location, and year. Disorder-specific prevalence was multiplied by disability weights representing the severity of health loss associated with each disorder to estimate years lived with disability (YLDs). Deaths due to anorexia nervosa were assessed with a Cause of Death Ensemble modelling strategy to estimate deaths by sex, age, location, and year, and then multiplied by the standard life expectancy at age of death to estimate years of life lost (YLLs). YLDs equalled disability-adjusted life-years (DALYs) for all mental disorders except anorexia nervosa (the only mental disorder considered as an underlying cause of death in GBD), for which DALYs represented the sum of YLDs and YLLs. We presented prevalence, deaths, YLDs, YLLs, and DALYs as counts, age-specific rates per 100\u2008000 population, and age-standardised rates per 100\u2008000 population. We estimated 1\u00b717 billion (95% uncertainty interval 1\u00b706-1\u00b731) prevalent cases of mental disorders globally in 2023, equivalent to an age-standardised prevalence rate of 14\u2008210\u00b77 cases (12\u2008849\u00b75-15\u2008940\u00b71) per 100\u2008000 population. These estimates represented a 95\u00b75% (75\u00b70-121\u00b72) increase in prevalent cases and 24\u00b72% (11\u00b74-41\u00b74) increase in age-standardised prevalence rate between 1990 and 2023. All mental disorders showed increases in prevalent cases between 1990 and 2023, while notable increases were seen in age-standardised prevalence rates for anxiety disorders, major depressive disorder, dysthymia, anorexia nervosa, bulimia nervosa, schizophrenia, and conduct disorder. There were an estimated 171 million (127-228) DALYs due to mental disorders globally across sex and age in 2023, equivalent to an age-standardised DALY rate of 2070\u00b75 DALYs (1519\u00b71-2750\u00b75) per 100\u2008000 population. Mental disorders contributed to 6\u00b71% (4\u00b78-7\u00b76) of all-cause DALYs in 2023, making them the fifth leading cause of global DALYs (up from 12th in 1990). DALYs were almost entirely composed of YLDs. Mental disorders were the leading cause of YLDs in 2023 (up from second in 1990), explaining 17\u00b73% (14\u00b78-20\u00b76) of all-cause global YLDs. Leading causes of mental disorder DALYs were anxiety disorders (ranked 11th among the 304 diseases and injuries at Level 4 of the GBD cause hierarchy), major depressive disorder (15th), and schizophrenia (41st). Globally in 2023, mental disorder age-standardised DALY rates were higher among females (2239\u00b76 [1643\u00b77-3014\u00b71] per 100\u2008000) than among males (1900\u00b72 [1399\u00b78-2510\u00b78] per 100\u2008000), and peaked in the 15-19 years age group (2617\u00b73 [1850\u00b76-3696\u00b78] per 100\u2008000). All locations showed increased mental disorder DALY rates in 2023 compared with 1990, ranging across countries and territories from 1302\u00b74 (952\u00b77-1683\u00b77) per 100\u2008000 in Viet Nam to 3555\u00b78 (2661\u00b79-4715\u00b70) per 100\u2008000 in the Netherlands. Across SDI quintiles, DALY rates ranged from 1853\u00b70 (1352\u00b71-2469\u00b73) per 100\u2008000 for middle SDI to 2184\u00b71 (1606\u00b71-2890\u00b73) per 100\u2008000 for high SDI. A significant health burden was imposed by mental disorders in all countries and territories in 2023, irrespective of the health resources available. In some instances, this burden has increased over time and is unevenly distributed across populations. Stronger surveillance systems, particularly in low-income and middle-income countries, are required. Additionally, we need more coordinated and inclusive policies to reduce the burden through early treatment and prevention, tailored to sex and age differences across locations.

Of those, 44.8% (n\u00a0=\u00a096) were HCPs, with the remaining consisting of people living with MND, genetic carriers, and carers. The following areas were rated as extremely important and should be included in the guideline: diagnosis, service delivery models, clinical care management, caregiver support, and palliative care; while views on genetic testing and cognitive assessment were mixed. Participants highlighted a need for holistic care which considered emotional/psychological and physical aspects of MND. People with MND and their carers want the Australian MND care guideline to highlight proactive and coordinated support prioritising quality of life, while maintaining independence for as long as possible. Identifying priorities is a fundamental step that will shape the forthcoming Australian MND care guideline. This methodology ensures the voices of those with lived experience and interest holders are incorporated from the outset. The responses to the online survey highlight the importance of proactive, coordinated, and multidisciplinary approaches for people living with motor neurone disease (MND).Holistic care should be integrated into healthcare settings that address both the physical and emotional/psychological needs of individuals with MND and their carers.Early intervention and ongoing review in areas such as nutrition, respiratory management, communication, and assistive technologies are critical to support optimal outcomes.The responses highlight the need for clear communication pathways and equitable access to healthcare and support services across Australia.Incorporating the perspectives of people with MND, carers, and healthcare professionals into guideline development can ensure rehabilitation practices are person-centred, responsive, and aligned with lived experiences."

In neurodegenerative diseases affecting the brainstem-such as progressive supranuclear palsy (PSP), amyotrophic lateral sclerosis (ALS), and multiple system atrophy (MSA)-bulbar dysfunction often impairs tongue propulsion and motility, affecting both swallowing (dysphagia) and phonation (dysarthria). This study aimed to investigate whether vowel-based acoustic features are associated with swallowing severity in brainstem-related disorders and to explore their potential as surrogate markers of bulbar involvement. Methods: This was a cross-sectional observational study. Thirty-one patients (13 PSP, 12 ALS, 6 MSA) underwent clinical dysarthria assessment, acoustic analysis of the first (F1) and second (F2) formants during sustained phonation of /a/, /i/, /e/, and /u/, and swallowing evaluation using standardized clinical scales (DOSS, FOIS, ASHA-NOMS) and fiberoptic endoscopic evaluation (Pooling Score, Penetration-Aspiration Scale). The vowel space area (tVSA, qVSA) and Formant Centralization Ratio (FCR) were computed. Results: Significant correlations emerged between acoustic vowel metrics and dysphagia severity, especially for liquids. The FCR showed strong correlations with DOSS (\u03c1 = -0.660, p < 0.0001), FOIS (\u03c1 = -0.531, p = 0.002), ASHA-NOMS (\u03c1 = -0.604, p < 0.0001), and instrumental scores for liquids: the Pooling Score (\u03c1 = 0.538, p = 0.002) and PAS (\u03c1 = 0.630, p < 0.0001). VSA measures were also associated significantly with liquid swallowing impairment. F2u correlated with dysarthria severity and all liquid-related dysphagia scores. Conclusions: Vowel-based acoustic parameters, particularly FCR and F2u, reflect the shared neuromotor substrate of articulation and swallowing. Acoustic analysis may support early detection and monitoring of bulbar dysfunction, especially where instrumental assessments are limited."

A cross-sectional sample of 100 individuals, including patients with ALS\u00a0and individuals with nonneurological dysphonia, was analyzed. Sustained vowel phonation was recorded and characterized using 26 variables, including standard acoustic measures (fundamental frequency -fo-, jitter, shimmer, and harmonics-to-noise ratio (HNR)) and 22 biomechanical parameters. Principal component analysis\u00a0was applied to investigate relationships among variables and reduce dimensionality. Unsupervised clustering was performed at both the variable level to identify functional groupings and the participant level to derive data-driven voice profiles. Cluster validity was assessed using internal indices. Post hoc statistical comparisons and chi-square tests were used descriptively to characterize between-cluster differences and their relationship with clinical categories. The first five principal components explained 70.7% of the total variance, revealing structured relationships between acoustic and biomechanical features. Participant level clustering consistently supported a two-profile solution. Fifteen voice parameters differed significantly between profiles after false discovery rate correction, with the largest effects observed for shimmer, HNR, and the biomechanical parameter Pr11, reflecting differences in vocal stability and noise-related characteristics. The identified profiles were not significantly associated with clinical diagnostic categories. An unsupervised multimodal analysis of sustained phonation revealed two coherent vocal profiles that transcend traditional diagnostic labels. These data-driven voice phenotypes may capture functional patterns of voice production and support future efforts toward more refined and personalized characterization of voice disorders."

In Cyprus, barriers such as long waiting lists, financial constraints, and limited public awareness restrict access to SLT services. University-led clinics offer a promising alternative by providing affordable, accessible care while training future clinicians. This study aimed to examine the demographic profiles, referral pathways, and diagnostic patterns of children accessing services at a university-led SLT clinic. By documenting referral trends and diagnostic outcomes, this study offers preliminary insights into patterns of service use and potential access disparities in the Cypriot context. Methods: A retrospective analysis was conducted using records from 235 children, aged 0;7 to 15 years, assessed at the University Rehabilitation Clinic between 2015 and 2024. Data included age, gender, socioeconomic status (SES), bilingualism, referral source, and diagnostic outcomes. Diagnoses were classified using Bishop et al.'s (2016) framework. Results: Significant associations were identified between age, parental education, referral source, and diagnostic category. Older children (9;1-12 years) demonstrated a markedly increased likelihood of receiving a developmental language disorder (DLD) diagnosis. Higher parental education levels and referrals from teachers or parents were also predictive of DLD and other communication impairments. Bilingualism was not a significant predictor of diagnostic category. Conclusions: The findings suggest that university-led clinics may serve as an important access point for underserved populations in Cyprus. This study provides preliminary evidence concerning demographic and referral factors that can inform outreach strategies and future service planning."

These disorders are clinically heterogeneous and therapeutically challenging, but advances in discovery science and trial methodology offer hope for translation to new treatments. Against this background, there is an urgent unmet need for biomarkers to aid with early and accurate diagnosis, prognosis and monitoring throughout the care pathway and in clinical trials.Investigations routinely used in clinical care and trials are often invasive, expensive, time-consuming, subjective and ordinal. Speech data represent a potentially scalable, non-invasive, objective and quantifiable digital biomarker that can be acquired remotely and cost-efficiently using mobile devices, and analysed using state-of-the-art speech signal processing and machine learning approaches. This prospective case-control observational study of multiple NDDs aims to deliver a deeply clinically phenotyped longitudinal speech dataset to facilitate development and evaluation of speech biomarkers. People living with dementia, motor neuron disease, multiple sclerosis and Parkinson's disease are eligible to participate. Healthy individuals (including relatives or carers of participants with neurological disease) are also eligible to participate as controls. Participants complete a study app with standardised speech recording tasks (including reading, free speech, picture description and verbal fluency tasks) and patient-reported outcome measures of quality of life and mood (EuroQol-5 Dimension-5 Level, Patient Health Questionnaire 2) every 2 months at home or in clinic. Participants also complete disease severity scales, cognitive screening tests and provide optional samples for blood-based biomarkers at baseline and then 6-monthly. Follow-up is scheduled for up to 24 months. Initially, 30 participants will be recruited to each group. Speech recordings and contemporaneous clinical data will be used to create a dataset for development and evaluation of novel speech-based diagnosis and monitoring algorithms. Digital App for Speech and Health Monitoring Study was approved by the South Central-Hampshire B Ethics Committee (REC ref. 24/SC/0067), NHS Lothian (R&D ref. 2024/0034) and NHS Forth Valley (R&D ref. FV1494). Results of the study will be submitted for publication in peer-reviewed journals and conferences. Data from the study will be shared with other researchers and used to facilitate speech processing challenges for neurological disorders. Regular updates will be provided on the Anne Rowling Regenerative Neurology Clinic web page and social media platforms. ClinicalTrials.gov NCT06450418 (pre-results)."

We evaluated the feasibility of a multimodal home monitoring protocol in ALS. Methods: We conducted a 3-month prospective cohort study at the University Medical Center Utrecht, Netherlands, with monthly home assessments of spirometry, accelerometry, speech, and questionnaires on functioning. The primary outcome was protocol adherence, defined as percentage of completed assessments. Secondary outcomes included acceptability ((totally) agree, neutral, (totally) disagree), and perceived burden, ranging from 0 (no burden) to 10 (extremely burdensome). Exploratory analyses were performed to evaluate changes in digital endpoints using linear mixed-effects models. Findings: Fifty patients with ALS were included (January 2023 - June 2025), of whom 47 (94%) completed the 3-month follow-up. Overall adherence was 83.2% (95% CI 76.9-88.6) and did not differ across modalities (p\u2009=\u20090.75). Adherers did not differ from non-adherers in either demographic or disease characteristics. In month 3, 93.0% to 95.3% of patients considered monthly remote assessments as acceptable, with a mean burden score of 2.0 (95% CI 1.7 to 2.3); burden was highest for speech (2.5) and the lowest for questionnaires (1.5). Digital endpoints showed significant change over 3\u2009months (all p\u2009<\u20090.05). Interpretation: This study demonstrates good adherence and acceptability of a multimodal remote monitoring protocol. Digital endpoints offer an innovative approach to capturing disease progression. Future research should assess its long-term feasibility, added value, and integration alongside established clinical outcomes."

BCIs have been used to translate the neural correlates of attempted speech into text1-3. However, text communication fails to capture the nuances of human speech, such as prosody and immediately hearing one's own voice. Here we demonstrate a brain-to-voice neuroprosthesis that instantaneously synthesizes voice with closed-loop audio feedback by decoding neural activity from 256 microelectrodes implanted into the ventral precentral gyrus of a man with amyotrophic lateral sclerosis and severe dysarthria. We overcame the challenge of lacking ground-truth speech for training the neural decoder and were able to accurately synthesize his voice. Along with phonemic content, we were also able to decode paralinguistic features from intracortical activity, enabling the participant to modulate his BCI-synthesized voice in real time to change intonation and sing short melodies. These results demonstrate the feasibility of enabling people with paralysis to speak intelligibly and expressively through a BCI."

Methods: A retrospective analysis(case series study) was conducted on the laryngeal functional characteristics of 7 patients [2 males, 5 females, age ranged from 43 to 76(60.85\u00b113.18)]with motor neuron disease who visited the voice clinic and were ultimately diagnosed by neurologists. The data included laryngostroboscopy, fiberoptic endoscopic examination of swallowing(FEES), acoustic analysis and laryngeal electromyography(LEMG). Descriptive methods were used for analysis. Results: \u2460There were 2 males and 5 females, with an average age of (60.85\u00b113.18) years. They had previously visited the otolaryngology department more than twice, visit frequency with an average of 3.57 and an average diagnosis time of 12.28 months. The main complaints of the patient at the time of treatment were voice change, dysphagia or vocal fatigue. \u2461LEMG: Among 7 cases, 4 cases demonstrated neurogenic damage, all of which were bilateral, and 3 cases showed normal findings on examination. Spontaneous potentials (SP) were present in three cases for more than 6 months, with the longest duration being 24 months. Three cases exhibited the coexistence of spontaneous potential and reinnervated motor unit potentials (MUPs), and two cases showed bundle tremor potential.\u2462Laryngostroboscopy revealed bilateral vocal fold asymmetry and glottic insufficiency in 7 cases, and decreased vocal cord movement in 4 cases, and vocal cord atrophy in 5 cases. FEES showed that 7 patients presented with mild to severe swallowing dysfunction, 3 cases had soft palate insufficiency and mild to severe food residues in the epiglottic valley and pyriform fossa. 1 case showed leakage and 1 case showed aspiration. Conclusions: Patients presenting with initial symptoms of abnormal laryngeal function should be vigilant for the possibility of motor neuron disease, especially when laryngostroboscopy reveals abnormal vocal fold movement and swallowing dysfunction. LEMG examination reveals bilateral neurogenic damage, prolonged spontaneous potential, coexistence of spontaneous potential and reinnervated MUPs, and the appearance of bundle tremor potential, which is beneficial for early detection of motor neuron disease. \u76ee\u7684\uff1a \u5206\u6790\u9996\u8bca\u55d3\u97f3\u79d1\u7684\u808c\u840e\u7f29\u4fa7\u7d22\u786c\u5316\uff08amyotrophic lateral sclerosis\uff0cALS\uff09\u60a3\u8005\u7684\u5589\u90e8\u75c7\u72b6\u3001\u4f53\u5f81\u548c\u5589\u808c\u7535\u56fe\u7279\u70b9\u3002 \u65b9\u6cd5\uff1a \u8be5\u75c5\u4f8b\u7cfb\u5217\u7814\u7a76\u5206\u67902021\u5e744\u6708\u81f32023\u5e744\u6708\u5728\u53a6\u95e8\u5927\u5b66\u9644\u5c5e\u4e2d\u5c71\u533b\u9662\u55d3\u97f3\u95e8\u8bca\u9996\u8bca\u3001\u6700\u7ec8\u786e\u8bcaALS\u76847\u4f8b\u60a3\u8005\uff3b\u7537\u60272\u4f8b\uff0c\u5973\u60275\u4f8b\uff1b\u5e74\u9f84\u4e3a43~76\uff0860.85\u00b113.18\uff09\u5c81\uff3d\u7684\u5589\u90e8\u75c7\u72b6\u3001\u4f53\u5f81\uff08\u9891\u95ea\u5589\u955c\u3001\u541e\u54bd\u5589\u955c\uff09\u3001\u58f0\u5b66\u8bc4\u4f30\u53ca\u5589\u808c\u7535\u56fe\u8d44\u6599\u3002\u91c7\u7528\u63cf\u8ff0\u6027\u65b9\u6cd5\u8fdb\u884c\u5206\u6790\u3002 \u7ed3\u679c\uff1a \u24607\u4f8b\u60a3\u8005\u65e2\u5f80\u5747\u5728\u8033\u9f3b\u54bd\u5589\u79d1\u5c31\u8bca2\u6b21\u4ee5\u4e0a\uff08\u4e2d\u4f4d\u6b21\u65703.57\u6b21\uff09\uff0c\u786e\u8bca\u65f6\u95f4\u4e3a12.28\u4e2a\u6708\u3002\u5c31\u8bca\u65f6\u4e3b\u8bc9\u4e3b\u8981\u4e3a\uff1a\u58f0\u97f3\u5636\u54d1\u3001\u53d1\u58f0\u8d39\u529b\u3001\u53d1\u58f0\u75b2\u52b3\u3001\u541e\u54bd\u5f02\u7269\u611f\u6216\u541e\u54bd\u56f0\u96be\u3001\u547c\u5438\u4e0d\u7545\u53ca\u8bf4\u8bdd\u542b\u7cca\u7b49\u3002\u2461\u5589\u808c\u7535\u56fe\uff1a7\u4f8b\u4e2d4\u4f8b\u63d0\u793a\u4e3a\u795e\u7ecf\u6e90\u6027\u635f\u5bb3\uff0c\u4e14\u5747\u4e3a\u53cc\u4fa7\uff0c3\u4f8b\u68c0\u67e5\u6b63\u5e38\uff1b3\u4f8b\u53d1\u73b0\u81ea\u53d1\u7535\u4f4d\u8005\u5747\u51fa\u73b0\u57286\u4e2a\u6708\u4ee5\u4e0a\uff0c\u6700\u957f\u8005\u8fbe24\u4e2a\u6708\uff1b3\u4f8b\u53d1\u73b0\u8fdb\u884c\u6027\u5931\u795e\u7ecf\u635f\u5bb3\u548c\u6162\u6027\u518d\u751f\u5e76\u5b58\uff0c2\u4f8b\u51fa\u73b0\u675f\u98a4\u7535\u4f4d\u3002\u2462\u9891\u95ea\u5589\u955c\uff1a7\u4f8b\u60a3\u8005\u5747\u51fa\u73b0\u53cc\u4fa7\u58f0\u5e26\u8fd0\u52a8\u4e0d\u5bf9\u79f0\u548c\u58f0\u95e8\u95ed\u5408\u4e0d\u5168\uff084\u4f8b\u5782\u76f4\u9762\uff0c3\u4f8b\u6c34\u5e73\u9762\uff09\uff0c5\u4f8b\u58f0\u5e26\u677e\u5f1b\uff0c3\u4f8b\u53cc\u4fa7\u58f0\u5e26\u8fd0\u52a8\u51cf\u5f31\uff0c1\u4f8b\u5355\u4fa7\u58f0\u5e26\u8fd0\u52a8\u51cf\u5f31\u3002\u541e\u54bd\u5589\u955c\uff1a7\u4f8b\u60a3\u8005\u5747\u663e\u793a\u6709\u8f7b-\u91cd\u5ea6\u4e0d\u7b49\u7684\u541e\u54bd\u529f\u80fd\u969c\u788d\uff0c3\u4f8b\u60a3\u8005\u8f6f\u816d\u95ed\u5408\u4e0d\u5168\uff0c\u8fdb\u98df\u540e\u4f1a\u538c\u8c37\u53ca\u68a8\u72b6\u7a9d\u5747\u6709\u8f7b\u5ea6-\u91cd\u5ea6\u4e0d\u7b49\u7684\u98df\u7269\u6b8b\u7559\uff0c1\u4f8b\u89c1\u6e17\u6f0f\uff0c1\u4f8b\u89c1\u8bef\u5438\u3002 \u7ed3\u8bba\uff1a \u9996\u53d1\u75c7\u72b6\u4e3a\u5589\u529f\u80fd\u5f02\u5e38\u7684\u60a3\u8005\uff0c\u5f53\u9891\u95ea\u5589\u955c\u53d1\u73b0\u58f0\u5e26\u8fd0\u52a8\u529f\u80fd\u5f02\u5e38\u7279\u522b\u662f\u58f0\u95e8\u95ed\u5408\u4e0d\u5168\u540c\u65f6\u4f34\u6709\u541e\u54bd\u5589\u955c\u4e0b\u541e\u54bd\u529f\u80fd\u5f02\u5e38\u65f6\uff0c\u9700\u8b66\u60d5ALS\u7684\u53ef\u80fd\uff0c\u5589\u808c\u7535\u56fe\u68c0\u67e5\u53d1\u73b0\u53cc\u4fa7\u795e\u7ecf\u6e90\u6027\u635f\u5bb3\u3001\u81ea\u53d1\u7535\u4f4d\u957f\u65f6\u95f4\u6301\u7eed\u5b58\u5728\u3001\u81ea\u53d1\u7535\u4f4d\u548c\u5bbd\u5927\u8fd0\u52a8\u5355\u4f4d\u7535\u4f4d\uff08motor unit potential\uff0cMUP\uff09\u5e76\u5b58\u4ee5\u53ca\u675f\u98a4\u7535\u4f4d\u7684\u51fa\u73b0\uff0c\u6709\u52a9\u4e8e\u65e9\u671f\u53d1\u73b0\u8bca\u65adALS\u3002."

Although acoustic voice analysis can detect phonatory alterations in ALS, its ability to differentiate clinical phenotypes remains limited. This study investigated whether biomechanical voice parameters provide complementary information for characterizing bulbar involvement across bulbar-onset ALS (ALS-B) and spinal-onset ALS (ALS-S) and explored their association with clinical and functional measures. Methods: This cross-sectional observational study included 50 patients with ALS (20 ALS-B, 30 ALS-S) and 50 controls with non-neurological voice disorders. Sustained vowel phonation was analyzed using acoustic measures and biomechanical voice parameters derived from a standardized model of vocal fold vibration. Perceptual voice severity was assessed using the GRBAS scale, while functional status was evaluated with the ALS Functional Rating Scale-Revised (ALSFRS-R) and the Barthel Index. Associations with clinical measures were explored in secondary analyses. Results: Compared with controls, ALS patients showed significant differences in acoustic measures and several biomechanical parameters related to glottal closure and vibratory stability. Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability. Unexpectedly, ALS-B showed greater perceptual voice severity and higher Barthel Index scores than ALS-S, while no differences were observed in global ALSFRS-R total scores. Conclusions: Biomechanical voice analysis appears to capture physiologically meaningful alterations in vocal fold function in ALS and provides complementary information for characterizing bulbar motor involvement across clinical phenotypes, particularly ALS-B disease. When combined with acoustic and clinical assessments, this approach may enhance the evaluation of bulbar involvement and functional status in ALS."

We aim to describe the most frequent otolaryngology (ORL) complaints and voice disturbances in patients with bulbar onset ALS. Retrospective cohort study. Single-center study with combined ORL and ALS clinic evaluation. Patients with a confirmed diagnosis of ALS following an ORL visit and who underwent comprehensive voice assessments between January 2021 and January 2023. Objective voice assessments. Glottal functional index (GFI), voice handicap index (VHI), reflux system index (RSI), and voice quality characteristics such as shimmer, jitter, maximum phonation time (MPT), and other essential parameters were assessed. One hundred and thirty-three patients (age 62.17\u00a0\u00b1\u00a010.79, 54.48% female) were included. Three patients were referred from the ORL department to the ALS clinic.

As interest in speech analysis grows, distinguishing between conditions becomes critical for reliable diagnosis and assessment. This pilot study explores speech biosignatures in two distinct neurodegenerative conditions: (1) mild traumatic brain injuries (eg, concussions) and (2) Parkinson disease (PD) as the neurodegenerative condition. The study included speech samples from 235 participants (97 concussed and 94 age-matched healthy controls, 29 PD and 15 healthy controls) for the PaTaKa test and 239 participants (91 concussed and 104 healthy controls, 29 PD and 15 healthy controls) for the Sustained Vowel (/ah/) test. Age-matched healthy controls were used. Young age-matched controls were used for concussion and respective age-matched controls for neurodegenerative participants (15 healthy samples for both tests). Data augmentation with noise was applied to balance small datasets for neurodegenerative and healthy controls. Machine learning models (support vector machine, decision tree, random forest, and Extreme Gradient Boosting) were employed using 37 temporal and spectral speech features. A 5-fold stratified cross-validation was used to evaluate classification performance. For the PaTaKa test, classifiers performed well, achieving F 1-scores above 0.9 for concussed versus healthy and concussed versus neurodegenerative classifications across all models. Initial tests using the original dataset for neurodegenerative versus healthy classification yielded very poor results, with F 1-scores below 0.2 and accuracy under 30% (eg, below 12 out of 44 correctly classified samples) across all models. This underscored the need for data augmentation, which significantly improved performance to 60%-70% (eg, 26-31 out of 44 samples) accuracy. In contrast, the Sustained Vowel test showed mixed results; F 1-scores remained high (more than 0.85 across all models) for concussed versus neurodegenerative classifications but were significantly lower for concussed versus healthy (0.59-0.62) and neurodegenerative versus healthy (0.33-0.77), depending on the model. This study highlights the potential of speech features as biomarkers for neurodegenerative conditions. The PaTaKa test exhibited strong discriminative ability, especially for concussed versus neurodegenerative and concussed versus healthy tasks, whereas challenges remain for neurodegenerative versus healthy classification. These findings emphasize the need for further exploration of speech-based tools for differential diagnosis and early identification in neurodegenerative health."

The aims were to (a) delineate temporal oral DDK deficits relating to the neuromotor pathology of ALS and (b) identify the optimal task-feature combinations to detect speech impairment in ALS. Mandibular myoelectric, kinematic, and acoustic data were acquired from 13 individuals with ALS and 10 healthy controls producing three alternating motion rate tasks and one sequential motion rate task. Twenty-seven features were extracted from the multimodal data, characterizing three temporal constructs: duration/rate, variability, and coordination. The disease impacts on these features were assessed across tasks, and the task eliciting the greatest disease-related change was identified for each feature. Such \"optimal\" task-feature combinations were fed into logistic regression to differentiate individuals with ALS from healthy controls. Temporal deficits in ALS were characterized by (a) increased duration and variability and reduced coordination of jaw muscle activities, (b) increased duration and variability and altered temporal symmetry of jaw velocity profile, (c) increased muscle-burst-to-peak-velocity duration, and (d) increased motion-to-voice onset duration. These temporal features were differentially affected across tasks. The optimal task-feature combinations, which were further clustered into three composite factors reflecting temporal variability, coarser-grained duration, and finer-grained duration, differentiated ALS from controls with an F1 score of 0.86 (precision = 1.00, recall = 0.75). Temporal oral DDK deficits are likely attributed to a hierarchy of interrelated neurophysiological and biomechanical factors associated with the neuromotor pathology of ALS. These deficits, as assessed crossmodally, provide previously unavailable insights into the multifaceted timing impairment of oromotor performance in ALS. The optimal task-feature combinations targeting these deficits show promise as quantitative markers for (early) detection of speech impairment in ALS."

Objective digital biomarkers, particularly those derived from acoustic and biomechanical analyses, demonstrate superior sensitivity compared to standard clinical ratings for capturing early disease progression. Speech rate, vowel acoustics, and articulatory precision are identified as sensitive metrics for the detection of subclinical bulbar motor neuron degeneration.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic lateral sclerosis, though primarily recognized for motor neuron degeneration, presents with non-motor and subtle bulbar manifestations that often precede definitive diagnosis. The literature confirms that in 25% of ALS sufferers, speech disorders occur as prodromal symptoms of the disease. Consequently, there is an urgent need to leverage digital technology to identify these latent changes. As one study notes, speech rate appears to decline significantly before the diagnosis of ALS is confirmed. The physiological basis for these alterations is supported by neuroimaging, which indicates that reduced speaking and articulation rates were associated with thinning in both oral motor cortices. Furthermore, the granularity afforded by digital tools allows for the identification of changes before they reach clinical thresholds, as automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Voice serves as a latent, multimodal biomarker reflecting neurological, cardiopulmonary, and psychological states.\n*   Automated segmentation algorithms can now identify syllable and phoneme positions during oral diadochokinesis with over 90% accuracy, providing a basis for objective monitoring.\n*   Biomechanical voice analysis captures physiologically meaningful alterations in vocal fold function, offering complementary information that transcends traditional clinical diagnostic labels.\n*   Changes in speech and swallowing function can be monitored remotely using smartphone applications, potentially reducing the need for frequent clinical hospital visits.\n*   There is a significant need for better standardized tools, as current outcome measurements for speech and swallow are deemed clinically meaningful by only a minority of practitioners.\n*   Vowel acoustic features (e.g., Formant Centralization Ratio) provide insight into the shared brainstem neuromotor substrate of both speech and swallowing.\n*   Research confirms the existence of coherent vocal profiles across patients that do not strictly align with existing clinical diagnostic categories.\n*   Early intervention protocols are limited by current guideline gaps, underscoring the necessity of individual-level predictive modeling.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

We evaluated the feasibility of a multimodal home monitoring protocol in ALS. Methods: We conducted a 3-month prospective cohort study at the University Medical Center Utrecht, Netherlands, with monthly home assessments of spirometry, accelerometry, speech, and questionnaires on functioning. The primary outcome was protocol adherence, defined as percentage of completed assessments. Secondary outcomes included acceptability ((totally) agree, neutral, (totally) disagree), and perceived burden, ranging from 0 (no burden) to 10 (extremely burdensome). Exploratory analyses were performed to evaluate changes in digital endpoints using linear mixed-effects models. Findings: Fifty patients with ALS were included (January 2023 - June 2025), of whom 47 (94%) completed the 3-month follow-up. Overall adherence was 83.2% (95% CI 76.9-88.6) and did not differ across modalities (p\u2009=\u20090.75). Adherers did not differ from non-adherers in either demographic or disease characteristics. In month 3, 93.0% to 95.3% of patients considered monthly remote assessments as acceptable, with a mean burden score of 2.0 (95% CI 1.7 to 2.3); burden was highest for speech (2.5) and the lowest for questionnaires (1.5). Digital endpoints showed significant change over 3\u2009months (all p\u2009<\u20090.05). Interpretation: This study demonstrates good adherence and acceptability of a multimodal remote monitoring protocol. Digital endpoints offer an innovative approach to capturing disease progression. Future research should assess its long-term feasibility, added value, and integration alongside established clinical outcomes.\n\nID: 42385762\nTitle: Global, regional, and national burden of tuberculosis and multidrug-resistant tuberculosis by HIV status, 1990-2023: a systematic analysis for the Global Burden of Disease Study 2023.\nAbstract: Tuberculosis (TB) is the leading global cause of death from a single infectious agent. Recent reductions in global health funding have threatened TB control, making comprehensive assessment of TB, HIV-related TB, and drug-resistant TB burdens before these disruptions essential for shaping effective responses. The WHO End TB Strategy sets targets of a 95% reduction in TB deaths and a 90% reduction in TB incidence between 2015 and 2035. Using results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023, this study aims to assess the burden of TB and multidrug-resistant TB (MDR-TB) across 204 countries and territories, and to evaluate progress towards the WHO End TB incidence and mortality targets. We quantified TB mortality using the Cause of Death Ensemble modelling platform with global vital registration, surveillance, verbal autopsy, and minimally invasive tissue sampling data. For TB morbidity estimation, we simultaneously modelled incidence, prevalence, and mortality by age and sex using DisMod-MR 2.1. A population attributable fraction (PAF) approach was applied to stratify morbidity and mortality estimates by HIV and drug-resistance status. We also calculated disability-adjusted life-years (DALYs) as the sum of years of life lost and years lived with disability. For the risk factor analysis, a comparative risk assessment framework was used and PAFs were derived for alcohol use, smoking, and high fasting plasma glucose to determine the proportion of TB burden associated with these risk factors. In 2023, there were an estimated 9\u00b711 million (95% uncertainty interval 8\u00b704-10\u00b73) incident cases of all-form TB, 1\u00b722 million (0\u00b798-1\u00b749) deaths, and 54\u00b76 million (43\u00b78-65\u00b75) DALYs globally. HIV-related TB comprised 781\u2008000 (690\u2008000-879\u2008000) incident cases and 210\u2008000 (142\u2008000-279\u2008000) deaths, contributing 11\u00b70 million (7\u00b756-14\u00b73) DALYs. MDR-TB accounted for 466\u2008000 (198\u2008000-1\u2008080\u2008000) incident cases, 102\u2008000 (31\u2008700-238\u2008000) deaths, and 3\u00b796 million (1\u00b731-9\u00b701) DALYs. From 2015 to 2023, global all-form TB incidence rates declined by 19\u00b72% (17\u00b78-20\u00b75) and deaths declined by 22\u00b76% (4\u00b77-35\u00b77); declines were larger for drug-susceptible TB than for MDR-TB. Sub-Saharan Africa and south Asia had the highest mortality burdens in 2023; reductions in all-form TB incidence and mortality were uneven between 2000 and 2023, with limited progress in both measures in Latin America and the Caribbean. Removing smoking, alcohol use, and high fasting plasma glucose would reduce global TB deaths to 768\u2008000 (592\u2008000-970\u2008000) and DALYs to 34\u00b79 million (27\u00b78-43\u00b78) in 2023; MDR-TB deaths would decrease to 77\u2008200 (23\u2008400-183\u2008000) and DALYs to 3\u00b712 million (1\u00b703-7\u00b729). Global progress towards WHO End TB targets is disparate and fragile. Although many regions achieved meaningful gains, others have stagnated in recent years. The complexity of TB prevention is amplified by divergent MDR-TB trends, the persistent burden of HIV, and growing exposure to modifiable risk factors. Recent volatility in global health financing threatens to further destabilise this vulnerable epidemiological landscape; concerted action is urgently needed to temper disruptions and preserve progress.

This study aimed to investigate the relationship between clinical dysphagia assessment tools (EAT-10, GUSS, RSST, and sialorrhea severity) and videofluoroscopic swallowing study (VFSS) findings in patients with ALS. Materials and Methods: This retrospective observational study included 60 patients with ALS classified as spinal-onset (n = 38) or bulbar-onset (n = 22). Relationships between clinical assessments and VFSS findings were analysed using Spearman correlation analysis. Exploratory multivariable regression and receiver operating characteristic (ROC) analyses were performed to evaluate associations and aspiration risk discrimination. Results: Strong negative correlations were observed between PAS-Liquid and RSST and GUSS scores, whereas EAT-10 showed a strong positive correlation (all p < 0.001). ROC analyses demonstrated good discriminative ability for aspiration risk for GUSS (AUC = 0.89), RSST (AUC = 0.88), and EAT-10 (AUC = 0.82). Patients with bulbar-onset ALS demonstrated higher penetration-aspiration severity and lower functional oral intake. Conclusions: Clinical dysphagia assessment tools showed significant associations with instrumental swallowing findings in ALS. GUSS and RSST demonstrated good discriminative ability for aspiration risk and may be clinically useful bedside screening tools. However, instrumental swallowing assessment remains essential whenever feasible.\n\nID: 42338888\nTitle: Interplay between B vitamins, fiber, and Bacteroides abundance: a predictive model for anxiety and depression in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive and incurable neurodegenerative disease that not only affects motor function but is also associated with gastrointestinal and emotional disturbances. Recent research highlights the potential role of gut microbiota and diet in modulating these symptoms, suggesting a complex interaction between nutrition, intestinal health, and presence of anxiety and depression in ALS patients. This study aims to investigate the relationship between dietary intake, gut microbiota composition, and presence of anxiety and depression in patients with amyotrophic lateral sclerosis (ALS). A cross-sectional study conducted with a sample of 48 patients with bulbar-onset or spinal-onset ALS from different regions of Spain. Dietary intake was assessed through 24-h records and food frequency questionnaires, while anxiety and depression were evaluated using validated scales that formed a latent factor called emotional distress. Stool consistency was assessed following the Bristol Stool Scale and the abundance of bacterial microbiota was quantified. Confirmatory factor analysis identified a nutritional factor composed of vitamins B1, B2, B9, C, and fiber, revealing a significant inverse association with anxiety and depression levels. The predictive model revealed both direct and indirect effects of this factor on presence of anxiety and depression, mediated by Bacteroides abundance and stool consistency. This model explained 19% of the variance in psychological distress. Our findings suggest that a diet rich in B vitamins, C vitamin and fiber may help improve emotional well-being in patients with ALS, highlighting the importance of nutritional strategies, as well as the role of Bacteroides related to stool consistency in patients with ALS.\n\nID: 42323648\nTitle: Delivering effective non-invasive ventilation in amyotrophic lateral sclerosis using intensive remote support (DENIM): protocol for an embedded process evaluation in a hybrid type 3 implementation-effectiveness trial.\nAbstract: Non-invasive ventilation (NIV) is the only intervention that significantly improves survival and quality of life in motor neuron disease, extending life by 8-13 months. However, at least half of patients are unable to reach the recommended\u2009\u2265\u20094\u00a0h daily NIV use, and current NHS services provide insufficient follow-up for intensive optimisation. Delivering Effective Non-Invasive ventilation in Motor neuron disease using intensive remote support (DENIM) is a stepped-wedge cluster randomised trial. This protocol describes a process evaluation embedded within DENIM aiming to understand how and why the implementation strategy works (or does not work) across different contexts. The process evaluation employs a convergent mixed-methods multiple-case study design across twelve NHS ventilation services. We developed a programme theory informed by Normalization Process Theory (NPT), the Consolidated Framework for Implementation Research and Expert Recommendations for Implementing Change, which states how the DENIM implementation strategy is expected to achieve normalisation of evidence-based NIV practice. Data collection across twelve sites include: ethnographic observations of patient-staff interactions; semi-structured interviews with staff (n\u2009=\u200924-48) and patients/carers (n\u2009=\u200924) exploring implementation experiences; the NoMAD questionnaire measuring normalisation perceptions from healthcare professionals within the services and NIV adherence data from participants' ventilators. Barriers and facilitators to research participation for underserved populations including ethnic minorities, those with low digital literacy, and women over 80 with bulbar onset disease will also be identified. Qualitative data will be analysed using NPT-informed thematic analysis. Integration occurs at three levels (design, methods, interpretation) with joint display tables presenting quantitative and qualitative findings alongside meta-inferences. This process evaluation will generate explanatory insights into how implementation strategies can address the evidence-to-practice gap in complex, technology-supported care for progressive diseases, with implications for health equity and wider NHS digital transformation.

It is widely assumed that cortical structures beyond motor neurons are relatively preserved, and patients in the end-stage ALS are regarded as being in complete locked-in syndrome (cLIS). However, emerging evidence suggests substantial heterogeneity in cognitive functioning among ALS patients, indicating possible extra-motor cortical involvement and impaired levels of consciousness. We report a case study assessing electrophysiological markers and auditory system integrity to evaluate the presence of covert consciousness in end-stage ALS. The patient was a 42-year-old woman with bulbar-onset, end-stage ALS, a six-year disease duration, and no means of communication. She underwent several EEG-based protocols, including resting-state EEG (RS-EEG), a passive auditory oddball paradigm, and 40\u2009Hz auditory steady-state responses (ASSR). Audiological evaluation comprised transient-evoked and distortion-product otoacoustic emissions, as well as auditory brainstem responses (ABR). RS-EEG was dominated by prefrontal 1-3\u2009Hz activity resembling frontal intermittent rhythmic delta activity. Power spectra were poorly differentiated and consistent with a 1/f profile. No event-related potentials were observed in the oddball paradigm, and no ASSR responses were detected. Audiological testing revealed absent otoacoustic emissions and ABR indicating severe to profound hearing loss. Our findings indicate severe cortical dysfunction and provide no electrophysiological evidence of covert consciousness. The electrophysiological profile closely resembles that observed in unresponsive wakefulness syndrome. This case supports the hypothesis that advanced ALS following cLIS onset may be more appropriately conceptualized as a disorder of consciousness rather than persistent cLIS.\n\nID: 42297978\nTitle: Long-term independent use of an intracortical brain-computer interface for speech and cursor control.\nAbstract: Brain-computer interfaces (BCIs) can provide naturalistic communication and digital access to people with severe paralysis by decoding neural activity associated with attempted speech and movement. Recent work has demonstrated highly accurate intracortical BCIs for speech and cursor control, but two critical capabilities needed for practical viability were unmet: independent at-home operation without researcher assistance and reliable long-term performance supporting accurate speech and cursor decoding. Here we demonstrate the independent and near-daily use of a multimodal BCI with novel brain-to-text speech and computer cursor decoders by a man with paralysis and severe dysarthria due to amyotrophic lateral sclerosis. Over nearly 2\u2009years, the participant used the BCI for more than 3,800\u2009h at home with no researchers present to maintain rich interpersonal communication with his family and friends, independently control his personal computer and sustain full-time employment-despite being paralyzed. He communicated 183,060 sentences-totaling 1,960,163 words-at an average rate of 56 words per minute. He labeled 92% of sentences as being decoded at least mostly correctly. In formal quantifications of performance where he was asked to say words presented on a screen, attempted speech was consistently decoded with more than 99% word accuracy (125,000 word vocabulary). The participant also used the speech BCI as keyboard input and the cursor BCI as mouse input to control his personal computer, enabling him to send text messages and emails and to browse the internet. These results demonstrate that intracortical BCIs have the potential to support independent use in the home, marking a critical step toward practical assistive technology for people with severe motor impairment.\n\nID: 42296263\nTitle: Whole-body muscle MRI improves diagnostic certainty in amyotrophic lateral sclerosis.\nAbstract: Introduction: Early diagnosis of amyotrophic lateral sclerosis (ALS) remains challenging due to the absence of a definitive biomarker and the difficulty of demonstrating widespread lower motor neuron (LMN) involvement. Whole-body muscle MRI (WB-MRI) enables comprehensive assessment of muscle involvement and may improve detection of LMN dysfunction. This study aimed to evaluate whether WB-MRI improves diagnostic certainty in ALS when combined with clinical and electromyography (EMG) assessment. Methods: In this prospective single-center study, 47 patients with ALS underwent clinical examination, EMG, and WB-MRI. Diagnostic classification according to the Awaji criteria was assessed using clinical and EMG data alone and after integration of MRI markers of LMN involvement, including fatty infiltration and muscle edema, or muscle edema alone as a surrogate marker. Results: WB-MRI identified additional LMN-involved regions in 27.7% of patients when both fatty infiltration and muscle edema were considered, and in 42.6% when considering muscle edema alone. This resulted in diagnostic upgrading in 14.9% and 25.5% of patients, respectively. The proportion of definite ALS increased from 8.5% to 17.0% when muscle edema alone was considered. MRI had limited impact on diagnostic classification according to the Gold Coast criteria. Among patients without LMN involvement on clinical and EMG assessment (all with bulbar-onset), 50% were reclassified after MRI. Conclusion: WB-MRI improves detection of LMN involvement and increases diagnostic certainty according to the Awaji criteria, with muscle edema appearing to be the most relevant MRI marker for integration into ALS diagnostic assessment.\n\nID: 42268433\nTitle: FUS-associated ALS in Taiwan: genetic spectrum, clinical features, and a founder haplotype of p.H517D.\nAbstract: To characterize the genetic spectrum and clinical features of FUS-associated amyotrophic lateral sclerosis (ALS) in a Taiwanese cohort and to investigate whether the recurrent p.H517D variant represents a founder mutation. All coding exons and flanking intronic regions of FUS were analyzed by Sanger sequencing in 650 unrelated Taiwanese patients with ALS. Clinical characteristics of patients carrying FUS variants were evaluated. Haplotype analysis using polymorphic microsatellite markers flanking FUS was performed to assess a potential founder effect of the p.H517D variant. Eight distinct heterozygous pathogenic FUS variants were identified in 11 probands and five affected relatives, including six missense and two frameshift variants. The most frequent variant was p.H517D, detected in four probands. A novel frameshift variant, p.G499Vfs*30, was identified as a de novo mutation in a juvenile-onset ALS patient. Compared with the non FUS-associated ALS cohort, patients with FUS-associated ALS had a significantly younger mean age at onset (40.1 vs 56.6\u00a0years) and more frequent bulbar onset (50% vs 19%). Haplotype analysis suggested a common founder for the p.H517D variant. FUS mutations accounted for 1.7% of ALS cases in this Taiwanese cohort. The recurrent p.H517D variant appears to represent a population-specific founder mutation. Patients with FUS variants presented with earlier disease onset and heterogeneous clinical phenotypes, and de novo variants contributed to juvenile-onset disease.\n\nID: 42263370\nTitle: Sensory abnormalities and entrapment neuropathies identified by nerve conduction studies in patients with amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder primarily affecting motor neurons; however, non-motor symptoms, including sensory and autonomic disturbances, are increasingly recognized. This retrospective cross-sectional study evaluated the frequency of sensory and entrapment neuropathies in 114 patients with ALS using electrodiagnostic (EDX) studies. Demographic characteristics, comorbidities, and sensory and autonomic symptoms were documented. Electrophysiological evidence of sensory neuropathy was identified in 20 patients overall (20/114, 17.5%), including 10 patients without diabetes mellitus (DM), whereas entrapment neuropathy was detected in 28 patients overall (28/114, 24.6%), including 16 of those without DM or hypothyroidism. Sensory neuropathy was significantly associated with both DM and a history of chronic disease. In contrast, these comorbid conditions were not significantly associated with entrapment neuropathy. Furthermore, patient-reported symptoms showed no correlation with electrophysiological evidence of sensory involvement on EDX. Sensory neuropathy was more frequent in patients with spinal-onset than bulbar-onset disease, although the difference was not statistically significant. This study confirms that sensory involvement is not uncommon in ALS. Although clinical symptoms are poor predictors, electrophysiological abnormalities consistent with sensory and entrapment neuropathies are common. A significant proportion of these abnormalities are idiopathic and may directly reflect the disease process itself, particularly in spinal-onset cases.\n\nID: 42241188\nTitle: The Unfinished Breath: Caregiver Perceptions of Terminal Events and Gaps in Amyotrophic Lateral Sclerosis Care in India.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder with a high symptom burden and limited survival. Little is known about the terminal phase experiences, symptom prevalence, and end-of-life care patterns of people with ALS (PALS) in India. This study aimed to assess terminal events and caregiver-reported outcomes in PALS to identify gaps in ALS care delivery in India. A cross-sectional telephonic survey was conducted among bereaved caregivers of PALS enrolled in the Neuropalliative and Supportive Care project between December 2021 and May 2024. A structured, validated questionnaire was used to collect data on demographics, terminal-phase symptoms, medical interventions, and the nature of death as perceived by primary caregivers. Descriptive statistics and appropriate statistical analyses were performed. A total of 130 caregivers participated in the survey; the majority (57.7%) were sons or daughters. Among the 130 PALS, 76 (58.5%) were men; 56.2% had limb onset and 43.8% had bulbar onset. The mean age at death was 53.5 \u00b1 11.4 years. Most patients (57.7%) died at home, and 29.2% experienced sudden death. Patients who died in the hospital were more likely to be on invasive mechanical ventilation ( P < 0.001). The most common terminal symptoms were breathlessness (79.2%), excessive oral secretions (54.6%), followed by anxiety or restlessness (44.6%). Only 20% received bilevel positive airway pressure, and 25.4% were on percutaneous endoscopic gastrostomy. A significant association was found between bulbar onset and assisted feeding ( P = 0.002). This study highlights the need for proactive, community-integrated palliative care services and emphasizes the urgency of early intervention and caregiver support to improve end-of-life experiences in PALS in India.\n\nID: 42236740\nTitle: HeyJay! A corpus of atypical speech for spoken language understanding and automatic speech recognition.\nAbstract: Speech technologies, such as automatic speech recognition or spoken language understanding, are not usually adapted to atypical speech, i.e., the speech of people with dysarthria, dysphonia, or another type of speech impairment. That prevents atypical speakers from leveraging speech assistants or other human-machine-interaction-powered platforms, which could make their lives easier or increase their independence. In this article, we present HeyJay!, a new corpus of atypical speech in English language from participants with neurodegenerative disorders, including Parkinson's Disease, or Amyotrophic Lateral Sclerosis. The current corpus version comprises 8,669 utterance recordings, including supervised transcriptions and intent annotations. In this study, we demonstrate the validity of the corpus by applying it to automatic speech recognition, spoken language understanding, and data augmentation tasks. Additionally, the dataset includes speech quality ratings for each participant, performed by expert speech and language pathologists. This corpus, the first one with intent annotation of atypical speech that is publicly available, is intended to create more fair speech technologies for atypical speakers by adapting and improving the state of the art, and to facilitate further research in the field.\n\nID: 42225765\nTitle: Longitudinal cognitive assessment using the Cumulus NeuLogiq platform in amyotrophic lateral sclerosis and frontotemporal dementia.\nAbstract: People living with ALS (plwALS) and/or FTD (plwFTD) often experience cognitive and behavioural changes. However, detection can be confounded due to factors like fatigue and testing anxiety. Cumulus neuroscience developed NeuLogiq(R), a multi-modal neurocognitive platform that can be used in clinic or at home, providing an ecologically valid measure of cognition. This study examined the feasibility and usability of NeuLogiq in plwALS, plwFTD, and controls, and compared performance on gold standard neuropsychological assessments with corresponding NeuLogiq digital assessments. Over 8 months, plwALS (n\u2009=\u200911), plwFTD (n\u2009=\u20097), and matched healthy controls (n\u2009=\u200910) completed longitudinal full neuropsychological assessment, as well as three 25-minute NeuLogiq Platform sessions every 2 weeks in their homes. Participants adhered well to the study schedule, conducting over 32/54 sessions on average. All groups rated usability in the 'good' or 'excellent' range and had\u2009>\u200980% complete data. Baseline group differences were detectable on both NeuLogiq digital assessments and benchmark neuropsychological assessments of similar cognitive domains. Longitudinal mixed effects models found that the ALS group showed decline on NeuLogiq measures of emotion recognition and speech fluency. These findings suggest that the NeuLogiq platform is feasible and usable for plwALS and plwFTD, and can identify cognitive deficits to a similar extent as benchmark assessments over time.\n\nID: 42214970\nTitle: The beat in speech: A window into the attentional mechanisms supporting the detection of non-adjacent dependencies.\nAbstract: Converging evidence suggests that musical training can elicit positive transfer effects across multiple domains of language processing, including grammar. In humans, exposure to musical rhythm induces beat and meter perception, which has been shown to enhance attentional allocation and temporal prediction. Theories hypothesize that the predictive gains intrinsic to music rhythmicity may exert cascading effects on syntactic processing by modulating sensitivity to speech prosody. From this perspective, learning should also be boosted insofar as prosody tends to align with grammatical structure. In the present study, we introduce a novel behavioural paradigm to investigate the link between rhythmicity and grammar learning by testing whether the rhythmic beat facilitates the detection of grammar-like structures in artificial languages (ALs), implemented as non-adjacent dependencies (NADs) between variable syllables forming a speech stream (e.g., PU reliably predicts KI in PUlaruKI). A total of 147 participants were exposed to four ALs that varied in rhythmic, grammatical structure, and the alignment between the two: (i) a beat-inducing rhythm with no NADs; (ii) a beat-hindering rhythm with NADs; (iii) a beat-inducing rhythm with embedded NADs temporally misaligned, and (iv) NADs aligned with beat time-points. Results of the implicit and, after exposure, explicit learning measures demonstrate enhanced learning when NADs are embedded within beat-inducing rhythmic structures. Together, these findings suggest that rhythm enhances predictive and attentional mechanisms implicated in grammar learning, underscoring their role in its acquisition.\n\nID: 42214042\nTitle: Diagnostic Revision From Primary Lateral Sclerosis to Amyotrophic Lateral Sclerosis: A Cohort Study.\nAbstract: Primary lateral sclerosis (PLS) is defined as a pure upper motor neuron syndrome and is a diagnosis of exclusion, amyotrophic lateral sclerosis (ALS) being the most likely alternative diagnostic consideration. A minimum disease duration of 2 years is required for the diagnosis of PLS, after which patients are classified as probable PLS (P-PLS) and subsequently as definite PLS (D-PLS) after 4 years. Our aim is to apply the current diagnostic criteria to a population-based cohort and investigate which clinical characteristics are associated with a diagnostic revision to ALS. This cohort study included patients meeting the current diagnostic criteria for PLS retrospectively from the Dutch Motor Neuron Disease Registry. Diagnostic revision to ALS was based on clinical assessment, EMG findings according to the revised El Escorial Criteria, or if patients had died from disease progression within 4 years of disease onset. Clinical characteristics were compared for patients who underwent diagnostic revision with ALS vs true PLS. Subdistribution hazard ratios (SHRs) for characteristics associated with diagnostic revision were determined using Fine-Gray regression. We included 478 patients (median age of onset 59.3 years, interquartile range 50.8-67.0, 47.9% female), of whom 311 (65.1%) met criteria for P-PLS and 167 (34.9%) for D-PLS at diagnosis. Eighty-eight patients (18%) underwent diagnostic revision to ALS, 76 cases (86%) before 4 years of disease duration. Patients whose diagnosis was revised to ALS had higher median age at onset (63.4 vs 58.0 years, p = 5.20 \u00d7 10-4), more often had bulbar onset (38.6% vs 19.7%, p = 6.19 \u00d7 10-4), and faster progression (median ALS Functional Rating Scale-revised slope 0.43 vs 0.18, p = 6.05 \u00d7 10-11). The risk of diagnostic revision increased if progression rate was faster (SHR 3.08 95% CI 1.69-5.60, p = 2.35 \u00d7 10-4) and if diagnosis was P-PLS compared with D-PLS (SHR 3.08, 95% CI 1.65-5.74, p = 3.96 \u00d7 10-4). In our cohort, most diagnostic revisions from PLS to ALS were in patients with a disease duration of less than 4 years. Besides disease duration, a faster progression rate was associated with diagnostic revision from PLS to ALS. Adding progression rate to the current diagnostic criteria could increase accuracy and help identify patients at higher risk of developing ALS.\n\nID: 42202251\nTitle: Beyond Time Saved: Implementation, Equity, and the Utility Threshold for Nursing AI Scribes.\nAbstract: Schwabe et al's pre-post time-motion study of a domain-specific artificial intelligence (AI) speech assistant used by nurses in German long-term care provides one of the few real-world, full-shift evaluations of an AI scribe deployed to a nonphysician workforce, with paired objective observation and self-reported outcomes. This commentary points to the implications of these findings that extend well beyond the time savings headline. The study reports substantial reduction in self-reported documentation time and increased satisfaction with the documentation system, yet workplace satisfaction and the perception that AI scribes are \"a good idea to implement\" did not improve. Taken together, these findings show three undertheorized issues for AI scribe implementation in nursing and long-term care. First, postimplementation increases in time spent reviewing entries and retrieving information indicate that AI scribes redistribute cognitive effort from authoring to verification, with unknown consequences for satisfaction, mastery, and error detection. Second, the apparent paradox of rising documentation satisfaction alongside falling expectations of AI quality represents user calibration. Third, the substantial equity considerations of automatic speech recognition documentation reflect a broader trend of AI scribe studies that treat equity as a caveat, rather than treating equitable performance as empirically measurable and testable across variations in linguistic styles, dialects, and social linguistic dimensions. To advance the field, the next generation of nursing AI scribe research must treat documentation as a heterogeneous bundle of authoring, reviewing, retrieving, and verifying activities with distinct satisfaction and error profiles; specify and validate end-user-defined anchor utilities, rather than having a narrow focus on diffuse improvement; and treat equity testing and reporting of both automatic speech recognition systems and workforce adoption as standard reporting expectations, rather than caveats.\n\nID: 42191539\nTitle: Discovering Hidden Vocal Subtypes: An Unsupervised Acoustic-Biomechanical Exploration of Voice Profiles.\nAbstract: This study aims to explore latent acoustic-biomechanical patterns of voice production using an unsupervised multivariate approach, and to identify data-driven vocal profiles across individuals with amyotrophic lateral sclerosis (ALS) and nonneurological\u00a0dysphonia. A cross-sectional sample of 100 individuals, including patients with ALS\u00a0and individuals with nonneurological dysphonia, was analyzed. Sustained vowel phonation was recorded and characterized using 26 variables, including standard acoustic measures (fundamental frequency -fo-, jitter, shimmer, and harmonics-to-noise ratio (HNR)) and 22 biomechanical parameters. Principal component analysis\u00a0was applied to investigate relationships among variables and reduce dimensionality. Unsupervised clustering was performed at both the variable level to identify functional groupings and the participant level to derive data-driven voice profiles. Cluster validity was assessed using internal indices. Post hoc statistical comparisons and chi-square tests were used descriptively to characterize between-cluster differences and their relationship with clinical categories. The first five principal components explained 70.7% of the total variance, revealing structured relationships between acoustic and biomechanical features. Participant level clustering consistently supported a two-profile solution. Fifteen voice parameters differed significantly between profiles after false discovery rate correction, with the largest effects observed for shimmer, HNR, and the biomechanical parameter Pr11, reflecting differences in vocal stability and noise-related characteristics. The identified profiles were not significantly associated with clinical diagnostic categories. An unsupervised multimodal analysis of sustained phonation revealed two coherent vocal profiles that transcend traditional diagnostic labels. These data-driven voice phenotypes may capture functional patterns of voice production and support future efforts toward more refined and personalized characterization of voice disorders.\n\nID: 42185781\nTitle: Association between creatinine-to-cystatin C ratio and ALSFRS-R across clinical phenotypes.\nAbstract: Reliable and accessible biomarkers for amyotrophic lateral sclerosis (ALS) are scarce. Creatinine (Cre) reflects muscle mass, whereas cystatin C (CysC) may reflect neurodegeneration without being directly influenced by muscle mass; however, both have limitations. We aimed to investigate whether the creatinine-to-cystatin C ratio (Cre/CysC) was cross-sectionally associated with functional status in patients with ALS. We retrospectively analyzed 30 patients diagnosed with ALS at the National Organization Hospital Okinawa Hospital between 2021 and 2024. Baseline ALS Functional Rating Scale-Revised (ALSFRS-R) scores and serum Cre and CysC levels were recorded. Associations with the ALSFRS-R were assessed using Spearman's correlation, with subgroup analyses by sex, site of onset, age at diagnosis, body mass index (BMI), and diagnostic delay. Multivariable analyses were performed to examine the independent association between Cre/CysC and ALSFRS-R while accounting for relevant clinical covariates. Cre/CysC showed a stronger cross-sectional correlation with ALSFRS-R (rs=0.648, p\u2009=\u20090.0001) than Cre alone (rs =0.427) or CysC (rs =-0.119). Exploratory subgroup analyses showed generally positive associations in several subgroups, although no statistically significant association was observed in the small bulbar-onset subgroup. In multivariable analysis adjusted for age at onset and diagnostic delay, Cre/CysC remained independently associated with ALSFRS-R (\u03b2\u2009=\u200920.1, 95% CI 6.41-33.9, p\u2009=\u20090.006). Given the small sample size and cross-sectional design, these findings should be interpreted as exploratory. Cre/CysC showed a stronger cross-sectional association with functional status than either marker alone. Because it is derived from routine laboratory tests, Cre/CysC may represent a simple exploratory measure associated with functional status in ALS. However, the present findings do not establish prognostic utility or fully account for disease stage and biological heterogeneity. Prospective longitudinal studies incorporating disease progression measures and broader clinical and genetic characterization are warranted.\n\nID: 42174849\nTitle: A Consensus Clustering Approach to Amyotrophic Lateral Sclerosis Phenotyping.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) phenotyping is a challenging task due to its heterogeneous nature and low prevalence. In this paper, we introduce a data-driven approach to support the characterization of ALS phenotypes based on clinical data from a battery of examinations. A consensus clustering method is proposed to identify stable clusters across multiple random data sub-samples, with the objective of discovering whether the retrieved patients' groups and related features align with clinical phenotypes and medical knowledge. Results suggest consistent profiles for bulbar onset ALS patients, driven by onset characteristics, whereas spinal onset ALS patients exhibit greater within-phenotype heterogeneity.\n\nID: 42167272\nTitle: Updated trends in the global prevalence and burden of mental disorders, 1990-2023: a systematic analysis for the Global Burden of Disease Study 2023.\nAbstract: The 2023 iteration of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) estimated prevalence, incidence, and health burden for 375 diseases and injuries, including 12 mental disorders. We assess past, current, and emerging trends in the prevalence and burden of mental disorders across sexes and age groups, for 21 regions, 204 countries and territories, and by Socio-demographic Index (SDI) quintile, from 1990 to 2023. Mental disorders included in GBD 2023 were anxiety disorders, major depressive disorder, dysthymia, bipolar disorder, schizophrenia, autism spectrum disorders, conduct disorder, attention-deficit hyperactivity disorder, anorexia nervosa, bulimia nervosa, idiopathic developmental intellectual disability, and a residual category of other mental disorders. A literature review identified epidemiological data for each disorder. These were analysed via a Bayesian meta-regression to estimate prevalence by disorder, sex, age, location, and year. Disorder-specific prevalence was multiplied by disability weights representing the severity of health loss associated with each disorder to estimate years lived with disability (YLDs). Deaths due to anorexia nervosa were assessed with a Cause of Death Ensemble modelling strategy to estimate deaths by sex, age, location, and year, and then multiplied by the standard life expectancy at age of death to estimate years of life lost (YLLs). YLDs equalled disability-adjusted life-years (DALYs) for all mental disorders except anorexia nervosa (the only mental disorder considered as an underlying cause of death in GBD), for which DALYs represented the sum of YLDs and YLLs. We presented prevalence, deaths, YLDs, YLLs, and DALYs as counts, age-specific rates per 100\u2008000 population, and age-standardised rates per 100\u2008000 population. We estimated 1\u00b717 billion (95% uncertainty interval 1\u00b706-1\u00b731) prevalent cases of mental disorders globally in 2023, equivalent to an age-standardised prevalence rate of 14\u2008210\u00b77 cases (12\u2008849\u00b75-15\u2008940\u00b71) per 100\u2008000 population. These estimates represented a 95\u00b75% (75\u00b70-121\u00b72) increase in prevalent cases and 24\u00b72% (11\u00b74-41\u00b74) increase in age-standardised prevalence rate between 1990 and 2023. All mental disorders showed increases in prevalent cases between 1990 and 2023, while notable increases were seen in age-standardised prevalence rates for anxiety disorders, major depressive disorder, dysthymia, anorexia nervosa, bulimia nervosa, schizophrenia, and conduct disorder. There were an estimated 171 million (127-228) DALYs due to mental disorders globally across sex and age in 2023, equivalent to an age-standardised DALY rate of 2070\u00b75 DALYs (1519\u00b71-2750\u00b75) per 100\u2008000 population. Mental disorders contributed to 6\u00b71% (4\u00b78-7\u00b76) of all-cause DALYs in 2023, making them the fifth leading cause of global DALYs (up from 12th in 1990). DALYs were almost entirely composed of YLDs. Mental disorders were the leading cause of YLDs in 2023 (up from second in 1990), explaining 17\u00b73% (14\u00b78-20\u00b76) of all-cause global YLDs. Leading causes of mental disorder DALYs were anxiety disorders (ranked 11th among the 304 diseases and injuries at Level 4 of the GBD cause hierarchy), major depressive disorder (15th), and schizophrenia (41st). Globally in 2023, mental disorder age-standardised DALY rates were higher among females (2239\u00b76 [1643\u00b77-3014\u00b71] per 100\u2008000) than among males (1900\u00b72 [1399\u00b78-2510\u00b78] per 100\u2008000), and peaked in the 15-19 years age group (2617\u00b73 [1850\u00b76-3696\u00b78] per 100\u2008000). All locations showed increased mental disorder DALY rates in 2023 compared with 1990, ranging across countries and territories from 1302\u00b74 (952\u00b77-1683\u00b77) per 100\u2008000 in Viet Nam to 3555\u00b78 (2661\u00b79-4715\u00b70) per 100\u2008000 in the Netherlands. Across SDI quintiles, DALY rates ranged from 1853\u00b70 (1352\u00b71-2469\u00b73) per 100\u2008000 for middle SDI to 2184\u00b71 (1606\u00b71-2890\u00b73) per 100\u2008000 for high SDI. A significant health burden was imposed by mental disorders in all countries and territories in 2023, irrespective of the health resources available. In some instances, this burden has increased over time and is unevenly distributed across populations. Stronger surveillance systems, particularly in low-income and middle-income countries, are required. Additionally, we need more coordinated and inclusive policies to reduce the burden through early treatment and prevention, tailored to sex and age differences across locations. Responding to the mental health needs of our global population, especially those most vulnerable, is an obligation, not a choice.

A cross-sectional survey assessing pwALS' perceptions of SLPs was distributed from October 2024 to January 2025 through electronic mailing lists of relevant professional organizations. A questionnaire examined pwALS' understanding of the SLP role, satisfaction levels, alignment between patient-reported impairments and SLP interventions, and perceived gaps in care. Responses were analyzed using descriptive statistics, with open-ended items analyzed using qualitative analysis. The 81 survey respondents consisted of pwALS (81.5%), caregivers (11.1%), family members (4.9%), and others (2.5%). Overall satisfaction with SLP care was high, though open-ended responses revealed gaps in understanding. Many were unaware of the full scope of SLP services; only 17.3% recognized cognitive evaluation and 8.6% cognitive therapy, compared with speech (77.8%) and swallowing (81.5%) evaluations. Reported services often did not align with communication and swallowing needs, but patients educated about a service were significantly more likely to use it. Overall satisfaction with SLP care was high; however, open-ended responses revealed gaps in understanding, unmet needs, and limited awareness of the full scope of SLP services. This misalignment highlights the need for improved patient and caregiver education regarding the role and timing of SLP involvement to enhance engagement, appropriate service use, and outcomes in ALS care.\n\nID: 42137113\nTitle: An interpretable, clinically grounded framework for digital speech biomarker development in neurodegenerative diseases.\nAbstract: Communication ability-a key determinant of quality of life-is frequently affected and progressively declines in neurodegenerative diseases. Effective management of progressive communication disorders requires a personalized approach to deliver timely interventions tailored to the evolving profiles of communicative impairment, thereby supporting functional communication throughout the disease course. To this end, reliable tools capable of detecting and quantifying both disease-specific patterns of communicative impairment and within-disease phenotypic variability are urgently needed. This study leverages Artificial Intelligence and advanced data analytics to develop an acoustic-based framework for automated extraction of interpretable, clinically grounded speech markers to enable objective assessment and phenotyping of progressive communication disorders. Three groups of participants, including 14 individuals with amyotrophic lateral sclerosis (ALS) and 15 individuals with Parkinson's disease (PD), alongside 10 neurologically healthy controls, performed a standardized oral passage reading task, yielding 739 speech samples. Fifty acoustic features were extracted using an automated analytic pipeline and subsequently clustered into six interpretable composite markers. The clinical utility of these markers was evaluated with the recorded speech samples by examining their (1) associations with standardized metrics of cognitive, motor speech, and overall communicative functions, (2) efficacy for detecting and differentiating disease-specific communicative impairment patterns in ALS and PD using supervised machine learning, and (3) utility for within-disease phenotyping and stratification using unsupervised clustering analysis. The markers effectively (1) detected subtle subclinical changes across multiple domains prior to substantial declines in functional communication outcomes; (2) differentiated disease-specific patterns of communicative impairment (multiclass area under the curve > 0.90); and (3) identified subgroups with distinct speech profiles within each disease. The findings support the potential of the proposed framework as a clinically translatable, objective tool to facilitate early detection, differential diagnosis, and phenotyping of progressive communication disorders, ultimately advancing personalized, measurement-based care in neurodegenerative diseases.\n\nID: 42133017\nTitle: Screening speech disorders in progressive neurological diseases via long-term average spectrum.\nAbstract: The long-term averaged spectrum (LTAS) may provide a universal method for capturing distinct patterns of dysarthria. This study aimed to evaluate the sensitivity of LTAS descriptors in a broad range of neurological diseases and various types and severities of dysarthria. Four spectral moments of spectral mean, spectral standard deviation, spectral skewness and spectral kurtosis based on LTAS were computed for reading passage collected from 461 speakers, including 306 healthy controls and 155 neurological patients secondary to Parkinson's disease (PD), progressive supranuclear palsy, multiple system atrophy (MSA), Huntington's disease, essential tremor, cerebellar ataxia (CA), multiple sclerosis (MS), and amyotrophic lateral sclerosis. Compared to controls, the spectral mean was significantly lower in PD and MS while elevated in CA. Significantly changed LTAS features were observed only in hypokinetic dysarthria and in mixed dysarthrias manifesting hypokinetic elements. Although LTAS features differed between controls and patients with varying degrees of dysarthria, there was no progressive increase in dysarthria severity. Our findings suggest that LTAS-based speech analysis may provide valuable cues to aid differential diagnosis among neurological diseases with overlapping clinical features. LTAS appears more informative when applied to specific diseases than to pooled dysarthria types arising from diverse neurological etiologies.\n\nID: 42112934\nTitle: Development of an Interpretable Deep Learning-Based Segmentation Algorithm for Automated Assessment of Oral Diadochokinesis in Progressive Neurological Diseases.\nAbstract: We aimed to develop a universal, fully automated segmentation algorithm that allows robust analysis of oral diadochokinesis across various neurological diseases, dysarthria types, and dysarthria severities. Recordings of sequential motion rates were collected from 231 subjects, including 80 healthy controls and 151 patients with neurological diseases such as amyotrophic lateral sclerosis, essential tremor, Huntington's disease, multiple sclerosis, multiple system atrophy, Parkinson's disease, progressive supranuclear palsy, and cerebellar ataxia. A robust automatic segmentation algorithm utilizing convolutional neural networks and rule-based postprocessing was developed and evaluated across disease type, dysarthria type, and dysarthria severity. The performance of the developed artificial intelligence-based algorithm was compared with a traditional signal processing-based segmentation approach. Our deep learning-based algorithm was able to correctly identify the position of individual syllables with a very high F1 score of 99.1%, compared to a signal processing-based approach with an F1 score of 97.7%. Using a 10-ms tolerance window, the deep learning-based algorithm achieved an average accuracy of 92.0% for the temporal detection of individual phoneme positions. Performance was strongly influenced by dysarthria severity, with accuracy reaching 94.7% in mild, 91.0% in moderate, and 83.1% in severe dysarthria. Disease and dysarthria type did not appear to have a substantial effect on algorithm performance. Our proposed deep learning-based algorithm provides reliable segmentation of syllable and individual phoneme positions during oral diadochokinesis across various disease types, dysarthria types, and dysarthria severities. The deep learning-based segmentation approaches have the potential to outperform the traditional signal processing methods for assessing oral diadochokinesis.\n\nID: 42166520\nTitle: Clinical characterization and natural history of ALS8/VAPB p.Pro56Ser: upper motor neurone signs, survival, and functional milestones in 78 patients.\nAbstract: Amyotrophic lateral sclerosis type 8 (ALS8), caused by the VAPB p.Pro56Ser mutation, is a rare familial motor neurone disease with an incompletely characterized profile. We aimed to characterize the clinical phenotype, upper motor neurone (UMN) sign prevalence, survival, and functional milestones. We retrospectively analyzed 78 patients with ALS8 confirmed via molecular testing or familial linkage analysis from 57 apparently unrelated families. UMN signs were assessed using a five-item composite of pyramidal signs. Survival and milestones were estimated using Kaplan-Meier analysis. Median age at onset was 44.9\u2009years; 51% were men. Onset was lumbar in 94%, proximally predominant. UMN signs were present in 53 patients; none exhibited clonus. At admission, 51% had spinal-onset ALS, 42% progressive muscular atrophy (PMA) and 6% flail leg; 30% of patients with PMA subsequently developed UMN signs. Survival was 21.9\u2009years; times to wheelchair dependence and noninvasive ventilation were 7.0 and 10.0\u2009years, respectively. Bulbar involvement occurred in 17 (21.8%) patients, predominantly as dysphonia. UMN status did not affect survival (p\u2009=\u20090.312). The standardized mortality ratio was 4.54 (95% CI 2.77-7.01), supporting disease-related excess mortality. ALS8 is a slowly progressive motor neurone disease with lumbar onset, ascending progression, and frequent but subtle UMN signs. Survival was markedly prolonged but functional decline followed a predictable sequence. These findings expand the phenotypic characterization of ALS8 and support genetic counseling and anticipatory management.\n\nID: 42152867\nTitle: The effects of a mobile healthcare application on speech and swallowing in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) impairs oral motor function, negatively affecting patients' speech and swallowing abilities, as well as quality of life. This study aims to evaluate the effectiveness of A Successful Swallowing with Effortful Training (ASSET) program, included in the 'The 365 Healthy Swallow Health Coach application' in preserving speech and swallowing abilities in ALS patients through self-training. In this 8-week quasi-experimental study, 13 participants were allocated to either the app-guided ASSET training group (n=7; three sessions per day, five days per week) or a usual-care control group (n=6) based on their clinical visit schedules. To evaluate changes over time and compare the two groups, linear mixed models were employed. Changes in ALS severity scale (ALSSS), Diadochokinetic (DDK) task, speech intensity, Speech Handicap Index-15, Dysphagia Handicap Index, Swallowing Quality of Life (SWAL-QOL), and Brief Inventory of Swallowing Assessment-15 were assessed. ALSSS speech scores was relatively preserved from 5.43 (95% CI 3.01-7.84) to 5.29 (95% CI 2.87-7.70) in the ASSET treatment group, but declined from 6.33 (95% CI 3.73-8.94) to 4.83 (95% CI 2.23-7.44) in the control group, with a significant group-by-time interaction (p=.017). DDK/tuh/and/kuh/were relatively preserved from 11.86 to 11.71 and from 12.29 to 11.57 respectively in ASSET group, but declined from 11.67 to 7.50 and from 11.83 to 7.17 in the control group, with significant interactions in/tuh/(p=.032) and/kuh/(p=.044). SWAL-QOL total score was relatively preserved from 155.86 to 149.71 in ASSET group, but declined from 154.67 to 125.17 in the control group, with a significant interaction (p=.011). The findings suggest that ASSET program may help preserve speech and swallowing function in patients with ALS. Future research should validate the ASSET program with a larger, adequately powered sample size.\n\nID: 42084465\nTitle: Lexical Properties of Stimuli in Standardized Articulation and Phonology Tests: A Short Report.\nAbstract: The purpose of the present study was to report the phonological neighborhood density, phonotactic probability, and word frequency of the stimuli in 12 commonly used articulation and/or phonological tests. We extend the work of Macrae (2017), who identified variability in stimulus items across consonant singletons, consonant clusters, vowels, phoneme complexity, and bound morpheme. This study sought to augment that work with a deeper analysis of lexical and sublexical features of these stimuli. The stimuli from 12 articulation and/or phonological tests were extracted, resulting in 667 stimuli. All stimuli were run through a phonological neighborhood density and phonotactic probability calculator. Word frequency was determined using Moe et al.'s (1982) database. Means and ranges for all lexical characteristics were computed across each of the 12 tests. Most stimuli were from sparse phonological neighborhoods, and included common sound sequences. Although the average word frequency value was in the high range, overall, very few test stimuli were high-frequency words. There was not one articulation and/or phonological test that considered or balanced these three lexical properties. We discuss the linguistic constraints surrounding developing such a test. We also discuss future research opportunities to examine if these lexical properties may result in over- and underidentification of children with speech sound disorders.\n\nID: 42011674\nTitle: Speech and swallow outcome measures for ALS and perspectives on remote monitoring: an international survey of speech & language therapists.\nAbstract: Dysarthria and dysphagia occur frequently in Amyotrophic Lateral Sclerosis (ALS). To manage these symptoms, speech & language therapists (SLTs) must identify relevant speech and swallow outcomes and select suitable outcome measurement instruments. Remote monitoring is an evolving mode of health status tracking. This survey aimed to establish SLT perspectives on ALS assessment regarding 1) the clinical meaningfulness of existing outcome measurement instruments 2) remote monitoring 3) usefulness of assessment devices for patient care and 4) bulbar function outcomes and measurement instruments useful for research studies. An online English-language survey was distributed internationally through gatekeepers and social media. Sixty-six SLTs responded from 13 countries. Current outcome measurement instruments were regarded as clinically meaningful in ALS by 35% for speech and 41% for swallow. Only 12% had access to remote monitoring, but 77% would like to avail of it, with 58% perceiving its potential to enhance care. Eighty-two percent deemed remote monitoring using digital patient-reported outcome measures (PROMs) useful. Speech intelligibility measurement was selected as the most useful communication outcome for remote monitoring (92%) and research (94%). SLTs agreed that speech intelligibility test software (72%), smart device apps (70%) and tongue pressure measurement devices (54%) are useful assessment equipment. SLTs want better measurement instruments for speech and swallow in ALS. They regarded technologies including remote monitoring incorporating digital PROMs as useful. Outcomes reflecting communication and swallow functional success level were deemed most useful. These survey findings can inform the selection of digital speech and swallow outcomes for ALS.\n\nID: 41892827\nTitle: Biomechanical Voice Parameters as Potential Biomarkers for Phenotype Differentiation in Amyotrophic Lateral Sclerosis: A Cross-Sectional Study.\nAbstract: Background/Objectives: Amyotrophic lateral sclerosis (ALS) is a clinically heterogeneous neurodegenerative disease in which bulbar involvement frequently affects speech and voice production. Although acoustic voice analysis can detect phonatory alterations in ALS, its ability to differentiate clinical phenotypes remains limited. This study investigated whether biomechanical voice parameters provide complementary information for characterizing bulbar involvement across bulbar-onset ALS (ALS-B) and spinal-onset ALS (ALS-S) and explored their association with clinical and functional measures. Methods: This cross-sectional observational study included 50 patients with ALS (20 ALS-B, 30 ALS-S) and 50 controls with non-neurological voice disorders. Sustained vowel phonation was analyzed using acoustic measures and biomechanical voice parameters derived from a standardized model of vocal fold vibration. Perceptual voice severity was assessed using the GRBAS scale, while functional status was evaluated with the ALS Functional Rating Scale-Revised (ALSFRS-R) and the Barthel Index. Associations with clinical measures were explored in secondary analyses. Results: Compared with controls, ALS patients showed significant differences in acoustic measures and several biomechanical parameters related to glottal closure and vibratory stability. Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability. Unexpectedly, ALS-B showed greater perceptual voice severity and higher Barthel Index scores than ALS-S, while no differences were observed in global ALSFRS-R total scores. Conclusions: Biomechanical voice analysis appears to capture physiologically meaningful alterations in vocal fold function in ALS and provides complementary information for characterizing bulbar motor involvement across clinical phenotypes, particularly ALS-B disease. When combined with acoustic and clinical assessments, this approach may enhance the evaluation of bulbar involvement and functional status in ALS.\n\nID: 41843813\nTitle: ALS motor phenotypes: a revised 'OPM' classification.\nAbstract: Defining motor phenotypes in amyotrophic lateral sclerosis (ALS) is important for individualized care and optimal therapeutic trial design. The \"ALS-OPM\" classification is based on the onset region (O), the propagation of motor symptoms (P), and the degree of clinical upper (UMN) and/or lower (LMN) motor neuron dysfunction (M). An international ALS expert focus group was held in September 2025, followed by a consensus process through which revisions of the OPM classification were finalized. Onset (O1-4) identifies first motor symptoms as relating to the head (O1), distal/proximal arm (O2d/p), respiratory/axial trunk (O3r/a), or distal/proximal leg (O4d/p). Onset symptoms are defined by weakness or slowed, poorly coordinated voluntary movements in the muscles of the head, arm, trunk, or leg, including dysarthria, dysphagia, dysphonia, dyspnea, and axial instability. Propagation (P1(n)) or absence of propagation (P0(n)) of motor symptoms from the onset region to another body region are designated, where n denotes the number of months from onset to propagation or assessment. The degree of UMN dysfunction (slowed, poorly coordinated voluntary movements, hyperreflexia and/or spastic muscle tone, emotional lability) and/or LMN dysfunction (weakness with associated muscle atrophy) is classified as follows: balanced UMN and LMN dysfunction (M0); dominant (M1d) or pure UMN dysfunction (M1p); dominant (M2d) or pure LMN dysfunction (M2p); and dissociated UMN/LMN dysfunction (M3), in which the arms and legs predominantly show LMN and UMN involvement, respectively. The revised ALS-OPM classification aims to make it routine, practical and feasible to capture phenotype in clinical practice and therapeutic trials.\n\nID: 41838635\nTitle: Comparing vowel intelligibility across interactive and non-interactive tasks in disordered speech.\nAbstract: The current study examines vowel intelligibility across interactive and non-interactive situations for individuals with dysarthria secondary to amyotrophic lateral sclerosis (PALS). The vowel space of these speakers is often characterized by centralization and lowering, negatively affecting intelligibility. In two experiments, listeners identified vowels produced by PALS in habitual speech (non-interactive), clear speech (non-interactive), and interactive matching. Clear speech and interactive matching elicited more intelligible vowels than habitual speech. Interactive matching productions were equal to or more intelligible than clear speech productions depending on vowel. These data represent a preliminary step to understanding how the dynamics of communicative interaction may shape vowel intelligibility.\n\nID: 41829459\nTitle: Quantification of Tongue Motor Dysfunction in Amyotrophic Lateral Sclerosis Using a Smartphone-Based Task and Deep Learning.\nAbstract: Bulbar dysfunction is a major complication of amyotrophic lateral sclerosis (ALS). This study aimed to develop and validate a simple, smartphone-based task for the objective assessment of tongue movements and to examine their association with clinical variables. 37 ALS patients and 20 age- and sex-matched controls performed a tongue lateralization task, recorded with a smartphone. A deep-learning U-Net++-based model was used for segmentation and feature extraction. The frequency and maximum amplitude of tongue movements were quantified. Clinical measures included the ALS Functional Rating Scale-revised (ALSFRS-r) bulbar sub-scores, tongue fasciculations, jaw jerk, and tongue \"spasticity\". Between-group differences and associations between tongue metrics and clinical features were assessed. The U-Net++-based model achieved robust segmentation performance. Patients showed lower tongue movement frequency than controls (0.14 vs. 0.40, t = -9.58, p < 0.001). Normalized frequency was associated with dysarthria (t = -3.13, p = 0.003) but not dysphagia (t = -1.05, p = 0.30). Normalized frequency (t = 2.77, p = 0.009) and tongue \"spasticity\" (t = -2.57, p = 0.015) were both associated with speech performance in a multiple-regression model (R = 0.51, adjusted R2 = 0.43). Our method provides an objective, minimally invasive measure of bulbar function in ALS, which correlates with clinical ratings and may detect subtle impairments not captured by standard assessments. This approach offers a promising tool for remote monitoring and may support more effective disease management.\n\nID: 41718496\nTitle: Timing of communication and technology control support in ALS - a systematic review.\nAbstract: Objective: To review evidence on the optimal timing of interventions that support communication and technology control for people living with Amyotrophic Lateral sclerosis (ALS). Methods: A systematic review was conducted following a pre-registered protocol. Databases were searched for studies involving people living with ALS that addressed timing of assistive technology interventions for communication or technology control. Screening and data extraction were completed in duplicate, findings were synthesized using a thematic analysis, and relevant findings presented as a descriptive summary. Results: Twenty-eight studies met the inclusion criteria. Evidence focused overwhelmingly on communication support rather than wider assistive technology interventions. Need for a communication aid typically occurs between one and five years from diagnosis and the timing of this varies significantly according to the site of onset of ALS. There are significant variations in the timing of changes for individuals within these groupings and there are likely a larger number of groupings that would be clinically useful. A significant correlation between changes in speaking rate and intelligibility has been shown. Once changes to speech do start to occur then the time to the loss of functional speech appears relatively consistent across the types of ALS. Conclusion: Current best practice guidelines are not reflective of the findings of this review and do not support professionals in identifying how to provide timely support. Monitoring speech changes systematically may support timely intervention. There is potential for individual level predictive modeling to help support people living with ALS to be proactive and prepared for changes.\n\nID: 41703059\nTitle: [Prevention in otology-the key to lifelong hearing health].\nAbstract: Hearing loss is a\u00a0major global health issue with potentially severe consequences for speech development, social integration, and cognitive health. A\u00a0significant proportion of this burden is preventable through targeted strategies applied across the human lifespan. This narrative review synthesizes key evidence-based preventive measures in otology and provides practical recommendations for clinicians. A\u00a0selective review of the current literature was conducted, including national clinical guidelines, systematic reviews, epidemiological studies, and pivotal clinical trials. Key preventive measures begin before birth with maternal vaccinations and hygiene counseling as well as screening for syndromes or congenital cytomegalovirus infection. Universal newborn hearing screening is a\u00a0cornerstone of early diagnosis and intervention, enabling superior outcomes with cochlear implantation or emerging gene therapies. Recommended childhood immunizations, noise protection, cautious use of ototoxic medications, and managing lifestyle-related risk factors are effective strategies for preventing acquired hearing loss. Furthermore, auditory rehabilitation with hearing aids or implants is crucial for tertiary prevention, mitigating secondary consequences such as social isolation and cognitive decline. A\u00a0multifaceted, proactive, life-course approach to hearing health is essential to reduce the burden of hearing loss. Otolaryngologists play a\u00a0central role in implementing these preventive strategies, from counseling expectant parents to ensuring timely rehabilitation in older adults.

Early detection of bulbar symptoms is crucial for timely diagnosis and intervention; however, variability in symptom progression complicates clinical assessment. This retrospective observational study aimed to classify patients with ALS into three groups - spinal onset, spinal onset with bulbar involvement, and bulbar onset - and to identify speech evaluation metrics that effectively differentiate these groups. Data from 68 patients with ALS were retrospectively analyzed. Speech samples were collected and evaluated for alternating motion rate (AMR), maximum phonation time (MPT), nasality, maximum tongue pressure (MTP), speech rate, and speech intelligibility. Group comparisons and receiver operating characteristic (ROC) curve analyses were conducted to assess discriminatory ability. AMR significantly differed among the three groups, with the spinal-onset group demonstrating the highest rates and the bulbar-onset group showing the lowest rates. ROC analysis indicated that AMR exhibited excellent discriminatory power, particularly in distinguishing spinal-from bulbar-onset ALS. Significant differences were also observed in MTP, nasality, speech rate, and speech intelligibility, although some metrics were less effective in differentiating the intermediate group. No significant group differences were found in MPT. These findings suggest that the AMR is a sensitive and easily administered measure for detecting bulbar symptoms and distinguishing ALS subtypes. The intermediate characteristics observed in the spinal-onset with bulbar involvement group support this classification as a distinct clinical phenotype. Combining AMR with secondary measures such as MTP, nasality, speech rate, and speech intelligibility may enhance early detection of bulbar symptoms and improve clinical decision-making.\n\nID: 41500873\nTitle: Voice-Based Prediction of Survival in Amyotrophic Lateral Sclerosis (ALS) Patients Using Biomechanical Acoustic Markers.\nAbstract: To evaluate whether voice-derived acoustic and biomechanical features can serve as non-invasive biomarkers for mortality-risk prediction and survival stratification in patients with amyotrophic lateral sclerosis (ALS). We conducted a retrospective study including 50 ALS patients evaluated in a phoniatrics consultation with available sustained vowel recordings, demographic data, and functional assessments. Nested logistic regression models were developed to predict clinical outcomes, progressively incorporating demographic variables, functional indices (Grade, Roughness, Breathiness, Asthenia, Strain, and Barthel), acoustic features (fundamental frequency, jitter, shimmer, harmonics-to-noise ratio), and biomechanical voice parameters (Pr1-Pr22). Model performance was assessed using receiver operating characteristic curves and area under the curve (AUC) comparisons via DeLong tests. Stepwise Akaike Information Criterion\u00a0(StepAIC) was applied to optimize the final model. A Cox proportional hazards model was used to evaluate the association between voice parameters and survival time. The final StepAIC model, which included a subset of biomechanical features, achieved excellent predictive performance (AUC\u00a0=\u00a00.903, 95% confidence interval: 0.816-0.989), significantly outperforming baseline and acoustic-only models. Bootstrapping confirmed the model's robustness and generalizability. Cox regression analysis showed that the derived risk scores stratified patients into tertiles with significantly different survival probabilities (log-rank P\u00a0<\u00a00.0001; hazard ratio for high vs. low-risk group\u00a0=\u00a011.2). Biomechanical voice features are strong predictors of mortality in ALS and outperform traditional clinical and acoustic indices. These findings support the integration of voice analysis into ALS monitoring protocols as a non-invasive, cost-effective, and scalable prognostic tool.\n\nID: 41477139\nTitle: Treatment of Neurogenic Voice Disorders.\nAbstract: This overview serves as a foundational resource for clinicians caring for neurologically complex patients presenting with voice complaints. Neurogenic voice disorders are diverse in their clinical presentations and therapeutic approaches. A thorough medical history, including family history, detailed laryngeal examination, voice assessments, and neuroimaging, are imperative, as well as a multidisciplinary, collaborative approach with neurologists, speech language pathologists, and patient caregivers. Disorders such as amyotrophic lateral sclerosis (ALS), cerebrovascular accidents (strokes), Huntington's disease, myasthenia gravis (MG), Parkinson's disease (PD), and voice tremor should be understood by otolaryngologists. Each condition presents unique challenges and requires tailored treatment strategies ranging from supportive therapies and pharmacological interventions to surgery. Voice management techniques, including the use of botulinum toxin for hyperkinetic disorders and deep brain stimulation for refractory cases, are highlighted as promising interventions.\n\nID: 41396714\nTitle: What can vowel acoustics reveal about the communicative participation of people living with ALS?\nAbstract: Objective: Bulbar dysfunction often diminishes the accuracy and speed of the tongue, lip, and jaw movements necessary for speech production. Vowel acoustic features derived from speech recordings can serve as sensitive markers of articulatory accuracy and movement timing. We examined whether degraded speech caused by amyotrophic lateral sclerosis (ALS), assessed through vowel acoustic features, was associated with communicative participation restrictions. As a secondary aim, we assessed the association of two global speech characteristics, rate and intelligibility, with vowel features and communicative participation. Materials & Methods: Thirty-three people with ALS (plwALS) recorded a reading passage and completed surveys using a smartphone application. Speaking rate and acoustic vowel features (duration, vowel articulation index [VAI]) were extracted from the recordings. Three speech-language pathologists rated speech intelligibility. Communicative participation was assessed using the Communicative Participation Item Bank (CPIB) short form. Bivariate correlation, partial correlation, and regression analyses were used to evaluate the associations between vowel features, intelligibility, speaking rate, and CPIB scores. Results: Significant bivariate correlations, ranging from rs\u2009=\u2009-0.39 to rs\u2009=\u20090.64, were found between speech variables and CPIB scores. A combined regression model including VAI, vowel duration, and sex explained 52% of the variance in CPIB scores. Including speaking rate or intelligibility in the partial correlation analysis attenuated the associations between vowel acoustics and CPIB. Conclusions: Vowel features and global dysarthria characteristics are linked to communicative participation in ALS. Clinical practices designed to target vowel production, speaking rate, and intelligibility may help to maintain daily communication in ALS.\n\nID: 41356579\nTitle: Effect of mobile phone applications on medication adherence among patients with coronary artery diseases: A scoping review.\nAbstract: Patients with cardiovascular disease rely on medication to achieve favorable long-term clinical results. Poor adherence has been linked to a relative increase in mortality of 50%-80% as well as higher health care costs. This scoping review thus aimed to explore the evidence of the effects of mobile health care apps on medication adherence in patients with cardiovascular diseases. A comprehensive data search and extraction was done in line with the updated Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews checklist. A total of 10 studies were included for the review. The mean pooled improvement in adherence was found to be 18% and the most effective tool was the digital therapeutics app discussed in Li et al's study. Smartphones and apps enhance coronary artery disease management by promoting medication compliance. Challenges include data security and smartphone usage among the elderly. Tailored apps or voice assistants offer potential solutions.\n\nID: 41341425\nTitle: Exploring Speech Biosignatures for Traumatic Brain Injury and Neurodegeneration: Pilot Machine Learning Study.\nAbstract: Speech features are increasingly linked to neurodegenerative and mental health conditions, offering the potential for early detection and differentiation between disorders. As interest in speech analysis grows, distinguishing between conditions becomes critical for reliable diagnosis and assessment. This pilot study explores speech biosignatures in two distinct neurodegenerative conditions: (1) mild traumatic brain injuries (eg, concussions) and (2) Parkinson disease (PD) as the neurodegenerative condition. The study included speech samples from 235 participants (97 concussed and 94 age-matched healthy controls, 29 PD and 15 healthy controls) for the PaTaKa test and 239 participants (91 concussed and 104 healthy controls, 29 PD and 15 healthy controls) for the Sustained Vowel (/ah/) test. Age-matched healthy controls were used. Young age-matched controls were used for concussion and respective age-matched controls for neurodegenerative participants (15 healthy samples for both tests). Data augmentation with noise was applied to balance small datasets for neurodegenerative and healthy controls. Machine learning models (support vector machine, decision tree, random forest, and Extreme Gradient Boosting) were employed using 37 temporal and spectral speech features. A 5-fold stratified cross-validation was used to evaluate classification performance. For the PaTaKa test, classifiers performed well, achieving F 1-scores above 0.9 for concussed versus healthy and concussed versus neurodegenerative classifications across all models. Initial tests using the original dataset for neurodegenerative versus healthy classification yielded very poor results, with F 1-scores below 0.2 and accuracy under 30% (eg, below 12 out of 44 correctly classified samples) across all models. This underscored the need for data augmentation, which significantly improved performance to 60%-70% (eg, 26-31 out of 44 samples) accuracy. In contrast, the Sustained Vowel test showed mixed results; F 1-scores remained high (more than 0.85 across all models) for concussed versus neurodegenerative classifications but were significantly lower for concussed versus healthy (0.59-0.62) and neurodegenerative versus healthy (0.33-0.77), depending on the model. This study highlights the potential of speech features as biomarkers for neurodegenerative conditions. The PaTaKa test exhibited strong discriminative ability, especially for concussed versus neurodegenerative and concussed versus healthy tasks, whereas challenges remain for neurodegenerative versus healthy classification. These findings emphasize the need for further exploration of speech-based tools for differential diagnosis and early identification in neurodegenerative health.\n\nID: 41928799\nTitle: Stable speech BCI performance during slow progression of ALS: A longitudinal ECoG study.\nAbstract: Electrocorticographic (ECoG) speech brain-computer interfaces (BCIs) show promise for restoring communication in amyotrophic lateral sclerosis (ALS), but the long-term stability of speech-related neural signals and decoding performance during disease progression remains unclear. We tracked signal characteristics and decoding over 25 months in a participant with ALS to determine how high-gamma (HG, 70-170 Hz) activity changes over time and whether these changes affect offline speech decoding. We implanted two 8\u00d78 subdural ECoG grids over left sensorimotor cortex (SMC) in a participant with slowly progressive bulbar variant ALS. Across 25 months, the participant performed an overt syllable-repetition task (12 consonant-vowel tokens) during simultaneous ECoG and audio recording. We quantified HG activation ratio (ActR), spectral signal-to-noise ratio (SNR; HG/HF, where HF = 300-499 Hz), and peak z-scored HG responses. Speech acoustics were evaluated using first/second formants (F1/F2) and the triangular vowel space area (tVSA). Offline EEGNet-based decoders were assessed in two stages: models trained on post-implant months 1-6 were tested on months 7-25, while models trained on stabilized data (months 7-11) were tested on the remaining period (months 12-25). Electrode-level saliency assessed spatial contributions to decoding. Acoustic analyses showed a significant reduction in tVSA over two years (-44.6 Hz2/day; P < 10-7), consistent with mild intelligibility decline. Neural metrics (ActR and SNR) followed a biphasic trajectory: increasing during the first 6 months, after which ActR stabilized (0.041%/day; P = 0.13), and SNR declined gradually (-0.46%/day, P < 10- 4). The model trained on months 1-6 achieved 55.7% accuracy (chance: 8.33%), but performance declined over time (-0.019%/day; P = 2.1\u00d710-4). Conversely, the model trained on months 7-11 achieved higher accuracy (65.9%) on subsequent data with no significant temporal decline (P = 0.23). Speech-related HG features exhibited an initial unstable period followed by a long-term gradual SNR reduction, potentially reflecting disease progression. Models trained after signal stabilization generalized robustly to data recorded over a year later. These findings confirm that despite reduced absolute HG power and mild acoustic degradation of speech, cortical features remain stable enough to support durable ECoG speech BCIs without frequent recalibration. These findings will motivate future adaptive calibration algorithms that account for slow signal changes while leveraging stable spatial representations in ventral SMC.

Hosted by the NIH-funded Bridge2AI-Voice consortium, the meeting convened global experts to address the methodological, ethical, and translational challenges of integrating voice-based artificial intelligence (AI) into healthcare. This mini-review synthesizes symposium insights across six domains: multimodal integration, FAIR (Findable, Accessible, Interoperable, Reusable) and CARE (Collective Benefit, Authority to Control, Responsibility, Ethics) data governance, clinical translation, interdisciplinary training, and cross-sector innovation. Research presented demonstrated voice as a latent, multimodal biomarker reflecting neurological, cardiopulmonary, and psychological states, while discussions emphasized ethical data practices and human-centered design. The implementation-focused panels underscored the importance of workflow alignment and usability for adoption in real-world care. Collectively, the symposium reflects a field advancing toward translational readiness and ethical accountability, positioning voice AI as a scalable, inclusive tool for next-generation healthcare.\n\nID: 41854033\nTitle: Identifying priorities for a national motor neurone disease (amyotrophic lateral sclerosis) guideline: results from an Australian online survey.\nAbstract: To identify the priorities of people living with motor neurone disease (MND), their carers, asymptomatic genetic carriers, and healthcare professionals (HCPs) in Australia, to inform the development of a national MND care guideline. An anonymous online survey was distributed via MND organisations and groups to the Australian MND community. Two hundred and fourteen individuals completed the survey. Of those, 44.8% (n\u00a0=\u00a096) were HCPs, with the remaining consisting of people living with MND, genetic carriers, and carers. The following areas were rated as extremely important and should be included in the guideline: diagnosis, service delivery models, clinical care management, caregiver support, and palliative care; while views on genetic testing and cognitive assessment were mixed. Participants highlighted a need for holistic care which considered emotional/psychological and physical aspects of MND. People with MND and their carers want the Australian MND care guideline to highlight proactive and coordinated support prioritising quality of life, while maintaining independence for as long as possible. Identifying priorities is a fundamental step that will shape the forthcoming Australian MND care guideline. This methodology ensures the voices of those with lived experience and interest holders are incorporated from the outset. The responses to the online survey highlight the importance of proactive, coordinated, and multidisciplinary approaches for people living with motor neurone disease (MND).Holistic care should be integrated into healthcare settings that address both the physical and emotional/psychological needs of individuals with MND and their carers.Early intervention and ongoing review in areas such as nutrition, respiratory management, communication, and assistive technologies are critical to support optimal outcomes.The responses highlight the need for clear communication pathways and equitable access to healthcare and support services across Australia.Incorporating the perspectives of people with MND, carers, and healthcare professionals into guideline development can ensure rehabilitation practices are person-centred, responsive, and aligned with lived experiences.\n\nID: 41406304\nTitle: Pridopidine treatment in ALS: subgroup analyses from the HEALEY ALS Platform trial.\nAbstract: Objectives: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with limited treatment options. Pridopidine, a selective sigma-1 receptor agonist, was evaluated in Regimen D of the HEALEY ALS Platform Trial. Although the primary endpoint (ALS Functional Rating Scale-Revised (ALSFRS-R) total score accounting for survival at 24\u00a0weeks) was not met, a predefined subgroup analysis suggested slowed disease progression in ALS patients with definite and early disease (<18\u00a0months from onset). This report presents an exploratory analysis that further investigates pridopidine in rapidly progressing participants with definite/probable ALS and early-disease, where treatment effects may be more pronounced. Methods: The randomized, double-blind, placebo-controlled phase 2 trial assigned participants to pridopidine 45\u2009mg bid or placebo, and placebo patients were shared across four trial regimens. The primary outcome was ALSFRS-R total score, with secondary outcomes assessing respiratory, bulbar, and speech functions. Results: Of 163 participants randomized to Regimen D, 72 met subgroup criteria (pridopidine: n\u00a0=\u00a037; shared placebo: n\u00a0=\u00a035). At week 24, pridopidine slowed ALSFRS-R total score decline (32%; \u03942.90, p\u00a0=\u00a00.03) and slowed decline of ALSFRS-R respiratory function (62%; \u03941.20, p\u00a0=\u00a00.03) and dyspnea (88%; \u03940.85, p\u00a0=\u00a00.005). ALSFRS-R-Bulbar function stabilized, with articulation and speaking rate declines reduced by 93% (\u03940.43, p\u00a0=\u00a00.0007) and 70% (\u03940.43, p\u00a0=\u00a00.002), respectively. Pridopidine was well-tolerated, with a safety profile comparable to placebo. All p values are nominal. Conclusion: Post hoc subgroup analysis suggests therapeutic benefits of pridopidine in patients that had definite/probable ALS and with early-disease progression, supporting further evaluation in a Phase 3 trial.\n\nID: 41360452\nTitle: Digital App for Speech and Health Monitoring Study (DASH): protocol for a prospective longitudinal case-control observational study for developing speech datasets in neurodegenerative disorders and dementia.\nAbstract: Neurodegenerative disorders (NDDs) represent an unprecedented public health burden. These disorders are clinically heterogeneous and therapeutically challenging, but advances in discovery science and trial methodology offer hope for translation to new treatments. Against this background, there is an urgent unmet need for biomarkers to aid with early and accurate diagnosis, prognosis and monitoring throughout the care pathway and in clinical trials.Investigations routinely used in clinical care and trials are often invasive, expensive, time-consuming, subjective and ordinal. Speech data represent a potentially scalable, non-invasive, objective and quantifiable digital biomarker that can be acquired remotely and cost-efficiently using mobile devices, and analysed using state-of-the-art speech signal processing and machine learning approaches. This prospective case-control observational study of multiple NDDs aims to deliver a deeply clinically phenotyped longitudinal speech dataset to facilitate development and evaluation of speech biomarkers. People living with dementia, motor neuron disease, multiple sclerosis and Parkinson's disease are eligible to participate. Healthy individuals (including relatives or carers of participants with neurological disease) are also eligible to participate as controls. Participants complete a study app with standardised speech recording tasks (including reading, free speech, picture description and verbal fluency tasks) and patient-reported outcome measures of quality of life and mood (EuroQol-5 Dimension-5 Level, Patient Health Questionnaire 2) every 2 months at home or in clinic. Participants also complete disease severity scales, cognitive screening tests and provide optional samples for blood-based biomarkers at baseline and then 6-monthly. Follow-up is scheduled for up to 24 months. Initially, 30 participants will be recruited to each group. Speech recordings and contemporaneous clinical data will be used to create a dataset for development and evaluation of novel speech-based diagnosis and monitoring algorithms. Digital App for Speech and Health Monitoring Study was approved by the South Central-Hampshire B Ethics Committee (REC ref. 24/SC/0067), NHS Lothian (R&D ref. 2024/0034) and NHS Forth Valley (R&D ref. FV1494). Results of the study will be submitted for publication in peer-reviewed journals and conferences. Data from the study will be shared with other researchers and used to facilitate speech processing challenges for neurological disorders. Regular updates will be provided on the Anne Rowling Regenerative Neurology Clinic web page and social media platforms.

Acoustic analysis provides an objective alternative, leveraging either \"global\" features extracted from the entire speech signal or \"segmental\" features derived from individual phonemes (e.g., vowels). While segmental features offer finer-grained acoustic insights, their extraction has traditionally required manual segmentation, making the process time-consuming. This study explored the use of the Montreal Forced Aligner (MFA) for automatic vowel segmentation and compared the diagnostic utility of global versus segmental acoustic features in two machine learning tasks: dysarthria detection (i.e., distinguishing healthy controls (HCs) from speakers with dysarthria) and dysarthria severity classification (i.e., pre-, early-, and late-symptomatic stratification). Speech data were collected from 104 speakers with MND and 99 HCs. Global features were computed from voiced segments, while segmental features were derived from automatically aligned vowels. Four tree-based classifiers - Decision Tree, Random Forest, XGBoost, and LightGBM - were trained using 10-fold cross-validation. Feature importance was assessed using SHAP values, and statistical tests identified features with significant group differences. The MFA achieved alignment accuracy of at least 86% for healthy and early-symptomatic speakers, declining to 72% in late-stage dysarthria. For dysarthria detection, global features were significantly more effective than segmental features only in the XGBoost model. In contrast, segmental features significantly outperformed global features in dysarthria severity classification across all ensemble classifiers. These findings support the use of automated segmental analysis as an objective, viable, and clinically meaningful approach for assessing dysarthria in MNDs.\n\nID: 41283495\nTitle: Acoustic Vowel Metrics as Correlates of Dysphagia and Dysarthria in Brainstem Neurodegenerative Diseases.\nAbstract: Background/Objectives: Swallowing and speech rely on shared brainstem circuits coordinating oropharyngeal motor functions. In neurodegenerative diseases affecting the brainstem-such as progressive supranuclear palsy (PSP), amyotrophic lateral sclerosis (ALS), and multiple system atrophy (MSA)-bulbar dysfunction often impairs tongue propulsion and motility, affecting both swallowing (dysphagia) and phonation (dysarthria). This study aimed to investigate whether vowel-based acoustic features are associated with swallowing severity in brainstem-related disorders and to explore their potential as surrogate markers of bulbar involvement. Methods: This was a cross-sectional observational study. Thirty-one patients (13 PSP, 12 ALS, 6 MSA) underwent clinical dysarthria assessment, acoustic analysis of the first (F1) and second (F2) formants during sustained phonation of /a/, /i/, /e/, and /u/, and swallowing evaluation using standardized clinical scales (DOSS, FOIS, ASHA-NOMS) and fiberoptic endoscopic evaluation (Pooling Score, Penetration-Aspiration Scale). The vowel space area (tVSA, qVSA) and Formant Centralization Ratio (FCR) were computed. Results: Significant correlations emerged between acoustic vowel metrics and dysphagia severity, especially for liquids. The FCR showed strong correlations with DOSS (\u03c1 = -0.660, p < 0.0001), FOIS (\u03c1 = -0.531, p = 0.002), ASHA-NOMS (\u03c1 = -0.604, p < 0.0001), and instrumental scores for liquids: the Pooling Score (\u03c1 = 0.538, p = 0.002) and PAS (\u03c1 = 0.630, p < 0.0001). VSA measures were also associated significantly with liquid swallowing impairment. F2u correlated with dysarthria severity and all liquid-related dysphagia scores. Conclusions: Vowel-based acoustic parameters, particularly FCR and F2u, reflect the shared neuromotor substrate of articulation and swallowing. Acoustic analysis may support early detection and monitoring of bulbar dysfunction, especially where instrumental assessments are limited.\n\nID: 41267082\nTitle: Expanding research and care for Leigh syndrome: efforts of a patient-led advocacy organization.\nAbstract: BACKGROUND: Leigh syndrome is a rare, progressive neurometabolic disorder caused by pathogenic variants in over 110 mitochondrial or nuclear genes. Its clinical and genetic heterogeneity creates challenges for diagnosis, care, and research. Cure Mito Foundation, a parent-led nonprofit established in 2018 to develop a gene therapy for SURF1-related Leigh syndrome, has since evolved into a global organization supporting individuals and families worldwide affected by all forms of Leigh syndrome. METHODS: This article describes the multifaceted efforts of Cure Mito Foundation to accelerate research and support for Leigh syndrome through family-led engagement and collaborative scientific partnerships. Strategies include funding the development of diverse disease models, gene therapies, drug repurposing pipelines, and a global patient registry. Emphasis is placed on co-production with affected families, sharing of biospecimens and data, and alignment with regulatory and research standards. RESULTS: The Leigh Syndrome Global Patient Registry comprises over 400 participants from 48 countries, with data made available to qualified researchers, and results shared regularly with the patient community to promote transparency and trust. Notable research accomplishments of Cure Mito include facilitating the development of multiple gene therapy candidates, patient-derived organoids and animal models, and repurposed drugs now entering early-phase trials. Cure Mito also played a key role in the launch of the Mitochondrial and Inherited Metabolic Disease Taskforce, led by the Critical Path Institute (C-Path), to integrate registry and clinical data into the Rare Disease Cures Accelerator platform. Additional efforts include community-developed educational tools, international awareness campaigns, and support programs tailored to the unique needs of Leigh syndrome families. CONCLUSIONS: Through relentless effort and dedication, the Cure Mito Foundation has shown that a small group of determined individuals can drive extraordinary change. By building a global patient registry, advancing data sharing and research, developing patient-centric education and support, and facilitating collaboration among scientists, clinicians, and families, the Foundation has created momentum toward effective treatments. With support from the Chan Zuckerberg Initiative\u2019s Rare As One grant, Cure Mito is poised to expand its impact even further. Leigh syndrome is a severe genetic disorder that begins in early childhood and leads to the gradual loss of physical and developmental abilities. It can be caused by variations in over 110 different genes and can affect multiple organs and systems in the body. Cure Mito Foundation is a nonprofit organization founded by parents of children with Leigh syndrome. Since its inception in 2018, the Foundation has evolved into a global initiative to support children and families affected by this rare condition. This article highlights the Cure Mito Foundation\u2019s efforts to advance research and provide support to families. The Foundation partners with scientists to explore potential treatments, including gene therapy, drug repurposing, and mitochondrial genome editing. It also established a global patient registry to collect valuable data from families, enabling researchers to better understand Leigh syndrome. The latest registry findings are included in this report. Importantly, families are not only participants in research - they also help guide it. Cure Mito ensures that patient and caregiver voices influence decisions, promote knowledge sharing, and foster a sense of support and community. The Foundation also offers practical resources for healthcare providers, caregivers, and families, including educational videos, a family planning guide, and a directory of medical experts. Through international collaboration and a strong, engaged community, Cure Mito Foundation is accelerating progress toward better care and future cures.\n\nID: 41156446\nTitle: Safety of FEES Performed by Speech-Language Pathologists and Physicians-Evidence Supporting Task Sharing from a Retrospective Observational Study of 964 Consecutive Examinations.\nAbstract: (1) Background: Fiberoptic Endoscopic Evaluation of Swallowing (FEES) is one of the two gold-standard tools for assessing oropharyngeal dysphagia (alongside Videofluoroscopic Swallowing Study). Although generally considered safe, concerns about complications persist, particularly in systems where FEES is not routine and professional roles differ. The aim of this study was to evaluate the safety of FEES performed by both speech-language pathologists (SLPs) and physicians, in order to provide evidence of its safety in a healthcare system where the procedure is not yet widely established and to identify patient subgroups potentially at higher risk of procedure-related complications. (2) Methods: This retrospective study analyzed 964 consecutive FEES procedures. Examinations were carried out by trained SLPs or physicians. Data included demographics, clinical status, operator qualifications, setting, and complications, classified as minor (vomiting, poor tolerance, early termination) or major (laryngospasm, epistaxis). (3) Results: The overall complication rate was 1.14% (11/964): 0.6% minor and 0.5% major. All events were self-limiting. Complication rates did not differ between SLPs (1.05%) and physicians (1.23%) or by experience, setting, drug use, penetration-aspiration scale score, or nasogastric tube. Four complications occurred in amyotrophic lateral sclerosis patients, suggesting higher risk. (4) Conclusions: FEES is safe and well tolerated when performed by either physicians or SLPs. These findings underscore the value of task sharing in dysphagia diagnostics, demonstrating that a shared model increases service capacity, reduces delays, and facilitates timely management of dysphagia.\n\nID: 41083392\nTitle: [Clinical analysis of a motor neuron disease-like phenotype associated with anti-IgLON5 disease].\nAbstract: We report a case of anti-IgLON5 disease with a motor neuron disease-like presentation admitted to the Department of Neurology, Xuanwu Hospital, Capital Medical University in July 2021. The patient was a 71-year-old female who presented with the chief complaint of limb weakness persisting for 4 months. She showed progressive limb weakness accompanied by muscle atrophy. Electromyography (EMG) revealed extensive neurogenic damage. Initial serum evaluation for neural-specific autoantibodies was positive for IgLON5-Ab (1\u2236100). Repeat testing confirmed IgLON5-Ab positivity with a titer of 1\u22361 000. The patient was diagnosed with anti-IgLON5 disease and treated with methylprednisolone and immunoglobulin, leading to clinical improvement. We found four relevant articles reporting a total of 11 similar cases. Thus, in this study, we analyzed a total of 12 cases, including our patient. Based on their clinical manifestations, these cases can be categorized into two types: amyotrophic lateral sclerosis(ALS)type and isolated bulbar type. Six cases-three males and three females-presented with the ALS type. Of these, three cases had diffuse limb weakness accompanied by muscle atrophy(two cases had diffuse hyperreflexia and one had a normal tendon reflex); one case presented with neck extensor weakness and bilateral asymmetric upper extremity weakness and was hyperreflexic at the bilateral patellar tendons; one case displayed asymmetric weakness in both lower limbs with normal deep reflexes, and one case exhibited neck weakness with hyperreflexia. EMG revealed diffuse lower motor neuron disease involving two or three regions. All patients tested positive for serum anti-IgLON5 antibodies. Four were also positive for anti-IgLON5 antibodies in cerebrospinal fluid, two were negative, and six were not tested. Among the 11 patients who received immunotherapy, 4 showed partial improvement in clinical symptoms, 2 exhibited transient improvement, 2 remained stable, and 3 showed no improvement. Testing for IgLON5-Ab should be considered among patients presenting with bulbar symptoms or ALS-like features, especially those with acute or subacute onset, rapid progression, autonomic dysfunction, vocal cord paralysis requiring tracheotomy, cognitive impairment, or involuntary movements. Early diagnosis and treatment may improve clinical symptoms and reduce adverse outcomes. \u672c\u6587\u62a5\u9053\u9996\u90fd\u533b\u79d1\u5927\u5b66\u5ba3\u6b66\u533b\u9662\u795e\u7ecf\u5185\u79d12021\u5e747\u6708\u6536\u6cbb\u76841\u4f8b\u8fd0\u52a8\u795e\u7ecf\u5143\u75c5\u6837\u8868\u578b\u7684\u6297IgLON5\u75c5\u75c5\u4f8b\u3002\u60a3\u8005\u4e3a71\u5c81\u5973\u6027\uff0c\u4e3b\u56e0\u80a2\u4f53\u65e0\u529b4\u4e2a\u6708\u5165\u9662\uff0c\u4e34\u5e8a\u8868\u73b0\u4e3a\u8fdb\u884c\u6027\u7684\u56db\u80a2\u65e0\u529b\u4f34\u808c\u8089\u840e\u7f29\uff0c\u808c\u7535\u56fe\u63d0\u793a\u5e7f\u6cdb\u795e\u7ecf\u6e90\u6027\u635f\u5bb3\uff0c\u8840\u6e05\u81ea\u8eab\u514d\u75ab\u6027\u8111\u708e\u76f8\u5173\u6297\u4f53\uff1aIgLON5-Ab\u9633\u6027\uff081\u2236100\uff09\uff0c\u590d\u67e5\u6297\u4f53\u6ef4\u5ea6\uff0c\u8840\u6e05IgLON5\u6297\u4f53IgG\u4e3a1\u22361 000\uff0c\u8bca\u65ad\u4e3a\u6297IgLON5\u75c5\uff0c\u5e94\u7528\u7532\u6cfc\u5c3c\u9f99\u53ca\u4e19\u79cd\u7403\u86cb\u767d\u6cbb\u7597\u6709\u597d\u8f6c\u3002\u540c\u65f6\u68c0\u7d22\u76f8\u5173\u6587\u732e4\u7bc7\uff0c\u5171\u62a5\u905311\u4f8b\u60a3\u8005\uff0c\u7ed3\u5408\u672c\u4f8b\u60a3\u8005\u517112\u4f8b\uff0c\u6839\u636e\u4e34\u5e8a\u8868\u73b0\u53ef\u5206\u4e3a2\u79cd\u7c7b\u578b\uff1a\u808c\u840e\u7f29\u4fa7\u7d22\u786c\u5316\uff08ALS\uff09\u578b\u548c\u5355\u7eaf\u5ef6\u9ad3\u578b\u3002\u67096\u4f8b\u8868\u73b0\u4e3aALS\u578b\uff0c\u7537\u60273\u4f8b\uff0c\u5973\u60273\u4f8b\uff0c\u5176\u4e2d\u56db\u80a2\u65e0\u529b\u4f34\u6709\u808c\u840e\u7f293\u4f8b\uff082\u4f8b\u56db\u80a2\u8171\u53cd\u5c04\u4ea2\u8fdb\uff0c1\u4f8b\u8171\u53cd\u5c04\u6b63\u5e38\uff09\uff0c\u53cc\u4e0a\u80a2\u4e0d\u5bf9\u79f0\u6027\u65e0\u529b\u4f34\u9888\u4f38\u808c\u65e0\u529b1\u4f8b\uff08\u53cc\u4fa7\u819d\u53cd\u5c04\u4ea2\u8fdb\uff09\uff0c\u53cc\u4e0b\u80a2\u4e0d\u5bf9\u79f0\u6027\u65e0\u529b1\u4f8b\uff08\u6df1\u53cd\u5c04\u6b63\u5e38\uff09\uff0c\u9888\u808c\u65e0\u529b1\u4f8b\uff08\u56db\u80a2\u6df1\u53cd\u5c04\u4ea2\u8fdb\uff09\uff1b\u808c\u7535\u56fe\u68c0\u67e5\u5747\u63d0\u793a\u4e0b\u8fd0\u52a8\u795e\u7ecf\u5143\u6027\u635f\u5bb3\uff0c\u7d2f\u53ca2\u62163\u4e2a\u533a\u57df\u3002\u6240\u6709\u60a3\u8005\u8840\u6e05\u6297IgLON5\u6297\u4f53\u5747\u4e3a\u9633\u6027\uff1b\u8111\u810a\u6db2\u6297IgLON5\u6297\u4f534\u4f8b\u9633\u6027\uff0c2\u4f8b\u9634\u6027\uff0c6\u4f8b\u672a\u68c0\u6d4b\u300211\u4f8b\u60a3\u8005\u7ed9\u4e88\u4e86\u514d\u75ab\u6cbb\u7597\uff0c4\u4f8b\u60a3\u8005\u4e34\u5e8a\u75c7\u72b6\u6709\u90e8\u5206\u6539\u5584\uff0c2\u4f8b\u6cbb\u7597\u540e\u77ed\u6682\u6027\u597d\u8f6c\uff0c2\u4f8b\u75c5\u60c5\u7a33\u5b9a\uff0c3\u4f8b\u60a3\u8005\u65e0\u6539\u5584\u3002\u8868\u73b0\u4e3a\u5ef6\u9ad3\u75c7\u72b6\u6216\u808c\u840e\u7f29\u4fa7\u7d22\u786c\u5316\u75c7\u7684\u60a3\u8005\uff0c\u5c24\u5176\u662f\u6025\u6027\u6216\u4e9a\u6025\u6027\u8d77\u75c5\uff0c\u8fdb\u5c55\u8fc5\u901f\uff0c\u6216\u5b58\u5728\u81ea\u4e3b\u795e\u7ecf\u529f\u80fd\u969c\u788d\u3001\u58f0\u5e26\u9ebb\u75f9\u9700\u8981\u6c14\u7ba1\u5207\u5f00\u3001\u8ba4\u77e5\u969c\u788d\u4ee5\u53ca\u4e0d\u81ea\u4e3b\u8fd0\u52a8\u7b49\u8868\u73b0\u65f6\uff0c\u9700\u8981\u8003\u8651\u5230\u6297IgLON5\u75c5\u7684\u53ef\u80fd\uff0c\u65e9\u671f\u8bca\u65ad\u53ca\u6cbb\u7597\u6216\u53ef\u6539\u5584\u60a3\u8005\u4e34\u5e8a\u75c7\u72b6\uff0c\u51cf\u5c11\u4e0d\u826f\u7ed3\u5c40\u3002.\n\nID: 40979210\nTitle: Patients and treatments in a neuropalliative outpatient clinic: an analysis of clinical routine data from five years of care.\nAbstract: The increasing prevalence of life-threatening neurological diseases raises the need for neuropalliative care. Setting up neurological palliative outpatient clinics is one way of addressing this need. This study aims to describe the patient clientele of a neurological palliative outpatient clinic and the spectrum of necessary treatments and interventions. In this longitudinal analysis, clinical routine data from a single centre were collected retrospectively from adult patients. The patient characteristics related to disease and treatment were evaluated descriptively. Factors influencing the need for ventilation were modelled in a logistic regression. The required treatment effort was modelled with a zero-inflated Beta regression. Results were reported as odds ratios with 95% confidence intervals (CIs). Two hundred and thirty-two patients were included in the study. Ninety-one patients were women, 141 were men, and the mean age was 55.42\u202fyears. Neuropalliative patients represented diagnoses such as amyotrophic lateral sclerosis (ALS) (n\u202f=\u202f81), ischemic stroke (n\u202f=\u202f15), intracerebral haemorrhage (n\u202f=\u202f15), Duchenne muscular dystrophy (n\u202f=\u202f12), or craniocerebral trauma (n\u202f=\u202f10). Palliative care counselling was the most common intervention for patients (n\u202f=\u202f203), their close relatives (n\u202f=\u202f177), and their nursing services (n\u202f=\u202f75). Respiratory therapy (n\u202f=\u202f188), speech and language therapy (n\u202f=\u202f145), and physiotherapy (n\u202f=\u202f143) were also frequently applied interventions. Sixty patients received botulinum toxin A treatment for hypersalivation, and 32 for spasticity. The odds of needing invasive ventilation increased by 3.7 (CI 1.7-7.8), and the need for mechanical insufflation-exsufflation increased by 2.2 (CI 1.1-4.3) in patients previously discharged from early neurological-neurosurgical rehabilitation. Prior intensive care treatment increased the odds of invasive ventilation by 5.1 (CI 2.2-11.5) and the use of mechanical insufflation-exsufflation by 2.3 (CI 1.1-4.8). Neuropalliative outpatient clinics demand a wide range of diagnostic measures and interventions as well as a multidisciplinary approach. Further research is necessary to investigate the relation between diagnosis and treatment needs. https://drks.de/search/en/trial/DRKS00030778, identifier DRKS00030778.\n\nID: 40808712\nTitle: Acoustic signatures of bulbar ALS: Predictive modeling with sustained vowels and LightGBM.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a degenerative neurologic disease with no definitive biomarkers for early detection. This paper discusses the use of acoustic analysis of sustained vowel phonations (SVP) and machine learning in ALS detection. An SVP corpus of 128 (64 /a/ and 64 /i/) from 31 patients with ALS and 33 healthy controls (HC) was employed. 131 acoustic features, including jitter, shimmer, Mel-Frequency Cepstral Coefficients (MFCCs), and Pathological Vibrato Index (PVI), were extracted. A LightGBM (Light Gradient Boosting Machine)-based model was built and optimized using 5-fold cross-validation to separate ALS cases. Model performance and feature importance were evaluated. The model performed well with high predictability, yielding an RMSLE of 0.162 and most predictions closely correlating with actual diagnoses. The top features obtained were S55_i, CCI(2), and dCCa(12), which were consistently at the top of the ranking list, indicating their role in ALS detection. The PVI was determined to be a significant biomarker with high values having high correlations with ALS diagnoses. But the multimodal nature of the predictive values indicated some flaws in generalization. This paper demonstrates the applicability of acoustic analysis and machine learning for early ALS detection. The proposed method provides an affordable, low-cost, and non-invasive way for ALS diagnosis with potential for application in telemedicine and clinical settings. Future research must expand datasets and integrate additional diagnostic modalities to improve the model's robustness and clinical translation.\n\nID: 40710301\nTitle: Management of Dysarthria in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) stands as the leading neurodegenerative disorder affecting the motor system. One of the hallmarks of ALS, especially its bulbar form, is dysarthria, which significantly impairs the quality of life of ALS patients. This review provides a comprehensive overview of the current knowledge on the clinical manifestations, diagnostic differentiation, underlying mechanisms, diagnostic tools, and therapeutic strategies for the treatment of dysarthria in ALS. We update on the most promising digital speech biomarkers of ALS that are critical for early and differential diagnosis. Advances in artificial intelligence and digital speech processing have transformed the analysis of speech patterns, and offer the opportunity to start therapy early to improve vocal function, as speech rate appears to decline significantly before the diagnosis of ALS is confirmed. In addition, we discuss the impact of interventions that can improve vocal function and quality of life for patients, such as compensatory speech techniques, surgical options, improving lung function and respiratory muscle strength, and percutaneous dilated tracheostomy, possibly with adjunctive therapies to treat respiratory insufficiency, and finally assistive devices for alternative communication.\n\nID: 40583986\nTitle: Bright tongue sign as a radiological clue of bulbar onset amyotrophic lateral sclerosis: A case report.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by degeneration of motor neurons, with the tongue often involved in clinical presentation. In this case, a 60-year-old female presented with progressive choking episodes and speech slurring over 9 months, exhibiting dysarthria, prominent tongue atrophy, fasciculations, and hyperreflexia. Needle electromyography (EMG) showed diffuse chronic neurogenic changes with signs of active denervation changes prominent on the tongue and right arm with normal sensory nerve studies. Magnetic resonance imaging (MRI) brain imaging revealed a Diffuse T1 Weighted image (T1WI) hyperintense of tongue known as \"bright tongue sign\" indicating fatty infiltration of tongue muscles, consistent with neurogenic atrophy. This case underscores the importance of recognizing this characteristic tongue hyperintensity as a valuable radiological clue in diagnosing bulbar-onset ALS and highlights the potential for early diagnosis to improve patient management and outcomes.\n\nID: 40564630\nTitle: Delivery of Pediatric Student-Led Speech and Language Therapy Services at a University Rehabilitation Clinic in Cyprus: Children Accessing Services.\nAbstract: Background/Objectives: Early identification and intervention in speech and language therapy (SLT) are essential for children's academic, social, and emotional development. In Cyprus, barriers such as long waiting lists, financial constraints, and limited public awareness restrict access to SLT services. University-led clinics offer a promising alternative by providing affordable, accessible care while training future clinicians. This study aimed to examine the demographic profiles, referral pathways, and diagnostic patterns of children accessing services at a university-led SLT clinic. By documenting referral trends and diagnostic outcomes, this study offers preliminary insights into patterns of service use and potential access disparities in the Cypriot context. Methods: A retrospective analysis was conducted using records from 235 children, aged 0;7 to 15 years, assessed at the University Rehabilitation Clinic between 2015 and 2024. Data included age, gender, socioeconomic status (SES), bilingualism, referral source, and diagnostic outcomes. Diagnoses were classified using Bishop et al.'s (2016) framework. Results: Significant associations were identified between age, parental education, referral source, and diagnostic category. Older children (9;1-12 years) demonstrated a markedly increased likelihood of receiving a developmental language disorder (DLD) diagnosis. Higher parental education levels and referrals from teachers or parents were also predictive of DLD and other communication impairments. Bilingualism was not a significant predictor of diagnostic category. Conclusions: The findings suggest that university-led clinics may serve as an important access point for underserved populations in Cyprus. This study provides preliminary evidence concerning demographic and referral factors that can inform outreach strategies and future service planning.\n\nID: 40553535\nTitle: Unilateral Vocal Cord Palsy as Presenting Feature of Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative pathology marked by the degeneration of upper and lower motor neurons, resulting in muscle weakness and atrophy, impairing motor function. Bulbar-onset ALS is a distinct clinical subtype, with initial involvement of bulbar motor neurons, often causing severe speech and swallowing difficulties. Despite its impact, bulbar-onset ALS, especially with rare symptoms like unilateral vocal cord palsy (UVCP), lacks extensive research. Here, we detail the case of a 79-year-old nonambulatory diabetic male with a 1-year history of hoarseness of voice, diagnosed with bulbar-onset ALS with UVCP. This underscores the importance of recognizing unusual presentations of ALS, particularly in geriatric populations, urging tailored medical evaluations for optimal care and improved outcomes in this challenging neurological condition.\n\nID: 40540830\nTitle: Pick's disease presenting as progressive apraxia of speech: Atypical clinical and neuroimaging features in three autopsy-confirmed cases.\nAbstract: Patients with progressive apraxia of speech (PAOS) often develop atypical parkinsonian features suggestive of corticobasal syndrome (CBS) or progressive supranuclear palsy (PSP), and typically have an underlying 4-repeat tauopathy at autopsy. We describe three cases of PAOS with underlying Pick's disease, a 3-repeat tauopathy, who lacked CBS or PSP features during life. We reviewed patients enrolled in the Neurodegenerative Research Group's ongoing studies on speech and language disorders and identified those with PAOS who had autopsy-confirmed Pick's disease. All patients had comprehensive neurologic, speech-language, and neuropsychological assessments, as well as multimodal neuroimaging, during life. Three female patients presented with phonetic PAOS without parkinsonism. Patient 1 had speech onset at age 54, later developed behavioral variant frontotemporal dementia (bvFTD), and died at 64. Patient 2 had speech onset at 47, early bvFTD features, prominent frontal and temporal involvement, and died at 53. Patient 3 had speech onset at 58, minimal behavioral changes, primarily frontal involvement on imaging, and died at 63. Our findings highlight that Pick's disease can present with PAOS and may be distinguished from 4R-tau PAOS by an absence of motoric CBS/PSP features and, in some cases, by prominent temporal hypometabolism with bvFTD development. These atypical features may prove useful in the antemortem identification of Pick's disease as a cause of PAOS.\n\nID: 40450589\nTitle: Differentiating upper- and lower motor neuron diseases using automated acoustic analysis.\nAbstract: Motor neuron diseases (MNDs) result in a spectrum of motor impairments, including considerable effects on speech function, which manifest as dysarthria-a motor speech disorder. Speech metrics are increasingly recognized as critical biomarkers with potential utility in disease diagnosis and phenotyping. This study aimed to (1) characterize acoustics of upper motor neuron (UMN) and lower motor neuron (LMN) dysarthria presentations in MNDs, and (2) identify relationships between bulbar disease severity scores and acoustic features, as these could collectively enable personalized approaches to management of these diseases. Data from 16 individuals with primary lateral sclerosis (PLS) representing UMN disease, 14 individuals with spinal and bulbar muscular atrophy (SBMA) representing LMN disease, and 25 neurologically healthy individuals were analyzed. Clinical measures were also collected from PLS and SBMA groups. All participants were remotely recorded performing passage reading, rapid syllable repetition, and vowel phonation. Fifty-two acoustic features were extracted representing articulation, phonation, prosody, resonance, and overall speech timing. Features were compared using Kruskal-Wallis tests for between-group comparisons and Spearman correlations between acoustic features and clinical scores. Articulatory and prosodic features best differentiated PLS, SBMA and controls. Correlations were observed in the PLS group between the clinical score and various articulatory features, most notably those indexing tongue and jaw movements. Our study demonstrated that acoustic assessment could capture fingerprints of dysarthrias associated with PLS and SBMA. These findings also demonstrate the potential for remote speech assessment to characterize diverse dysarthria profiles and pave the way for creating ways for personalized disease management approaches in clinical care and trials.\n\nID: 40407667\nTitle: Relationship Between Voice Analysis and Functional Status in Patients with Amyotrophic Lateral Sclerosis.\nAbstract: Background: Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease affecting both upper and lower motor neurons, with bulbar dysfunction manifesting in up to 80% of patients. Dysarthria, characterized by impaired speech production, is common in ALS and often correlates with disease severity. Voice analysis has emerged as a promising tool for detecting disease progression and monitoring functional status. Methods: This study investigates acoustic and biomechanical voice alterations in ALS patients and their association with clinical measures of functional independence. A descriptive observational case series study was conducted, involving 43 ALS patients and 43 age and sex matched controls with non-neurological voice disorders. Sustained vowel /a/ recordings were obtained and analyzed using Voice Clinical Systems\u00ae and Praat software (version 6.2.22). Biomechanical and acoustic parameters were correlated with ALS Functional Rating Scale-Revised (ALSFRS-R) and Barthel Index scores. Results: Significant differences were observed between ALS and control groups (elevated muscle force and tension and interedge distance in non-ALS individuals). Between bulbar and spinal ALS subtypes, elevated values were observed in certain parameters in Bulbar ALS patients, indicating irregular vocal fold contact and weakened phonatory control, while spinal ALS exhibited increased values, suggesting higher phonatory muscle tension. Elevated biomechanical parameters were significantly correlated with low ALSFRS-R scores, suggesting a possible relationship between voice measures and functional decline. However, acoustic measurements showed no relationship with performance status. Conclusions: These results highlight the potential of voice analysis as a non-invasive, objective tool for monitoring ALS stage and differentiating between subtypes. Further research is needed to validate these findings and explore their clinical applications.\n\nID: 40350485\nTitle: Advancing Future Amyotrophic Lateral Sclerosis Medicines by Incorporating The Patient Voice Into Patient-Centered Holistic Measurement Strategies for Clinical and Real-World Studies: Results from Targeted Literature Reviews.\nAbstract: This analysis sought to understand the patient experience in amyotrophic lateral sclerosis (ALS) and to assess whether commonly used clinical outcome assessments (COAs) reliably and validly capture that experience. Two targeted literature reviews were conducted to identify and describe key concepts potentially important to patients (signs, symptoms, impacts), and identify commonly used COAs in ALS. Insights gained were used to map target COAs to concepts identified as potentially relevant to patients and their caregivers. COAs of interest were further examined to evaluate evidence of their validity and reliability within ALS. Forty-three articles were identified for concept extraction. Signs and symptoms were identified across multiple themes: motor; non-motor; respiratory; cognitive; and behavioral. Patient impacts were identified across multiple themes: physical; functional; emotional; social; and other aspects of well-being. Caregiver impacts were identified across four themes: general; emotional; social; and physical. Of 236 unique COAs identified, 6 were found to provide the greatest coverage of potentially important concepts. Closer examination of these showed some evidence gaps supporting content validity and/or psychometric properties. Several concepts related to ALS were identified that are relevant to patients in their daily lives. We identified and reviewed COAs commonly used in assessing these concepts, and found gaps in their content validity and/or psychometric properties. These findings suggest the need for further testing/refinement of existing tools, and the opportunity to use other instruments alongside those most frequently used (e.g., ALSFRS-R) to comprehensively capture the patient experience of ALS in future clinical trial and real-world studies.\n\nID: 40324158\nTitle: Dysphagia Symptoms Contribute to Greater Care Partner Burden in Neurodegenerative Disease.\nAbstract: Providing care for family members with neurodegenerative diseases entails significant physical and psychosocial costs, increasing caregiver burden. Limited research exists on the factors contributing to dysphagia-related burden, particularly across disease trajectories. This study aimed to (a) determine if dysphagia-related burden predicts general caregiver burden, (b) identify predictors of dysphagia-related burden, and (c) examine relationships between dysphagia severity, disease severity, and dysphagia-related burden. Care partners (N = 211; 80% female; Mage = 60 \u00b1 14 years) from clinics in Canada, New Zealand, and the United States participated. Care recipients included those with amyotrophic lateral sclerosis (ALS; n = 48), dementia (n = 110), and Parkinson's disease (PD; n = 53). General burden was measured using the Zarit Burden Interview, while dysphagia-related burden was assessed via the Caregiver Assessment of Reported Experiences with Swallowing Difficulties. Multiple regression analyses examined predictors of general and dysphagia-related burden and their relationships to dysphagia and disease severity. Higher general burden was associated with female caregivers (\u03b2 = -.19, p = .05), higher education (\u03b2 = .16, p = .03), caring for someone with dementia (\u03b2 = .36, p = .01), and greater dysphagia-related burden (\u03b2 = .33, p = .01). Predictors of dysphagia-related burden included working caregivers (\u03b2 = .15, p = .01), increased dysphagia symptoms (\u03b2 = .77, p < .01), and caring for individuals with ALS or dementia (vs. PD; \u03b2 = -.16, p = .02). Dysphagia burden varied by disease severity and diet tolerance (p < .01). Managing dysphagia independently contributes to caregiver burden, potentially increasing burnout and nonadherence to clinical recommendations. Early, proactive inquiry about dysphagia-related care partner burden and provision of support to minimize burden should be considered early in disease management. https://doi.org/10.23641/asha.28843055.\n\nID: 42333954\nTitle: Thinning of the oral motor cortex is linked to impaired speech in amyotrophic lateral sclerosis.\nAbstract: Most individuals with amyotrophic lateral sclerosis (ALS) develop bulbar impairment as their disease progresses. The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech\u2011derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1\u2011weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS.\n\nID: 42091714\nTitle: The Dysphagia Outcome and Severity Scale (DOSS) and non-instrumental swallowing measures in amyotrophic lateral sclerosis.\nAbstract: To evaluate reliability of the Dysphagia Outcome and Severity Scale (DOSS) in Amyotrophic Lateral Sclerosis (ALS) patients, and to assess diagnostic accuracy of selected non-instrumental measures in defining swallowing safety in this population. One hundred and thirteen consecutive ALS patients underwent comprehensive dysphagia evaluation with fiberoptic endoscopic evaluation of swallowing (FEES) and were classified according to DOSS. Safe and unsafe swallowing were defined by DOSS levels 7-6 and 5-1, respectively. Patient-reported measures included ALS Functional Rating Scale-Revised swallow item (I-3) and Eating Assessment Tool-10 (EAT-10). Non-instrumental clinical measures were hyolaryngeal excursion, voluntary cough (VC), voice quality and reflexive cough/throat clearing (VRC), and maximum phonation time (MPT). Inter- and intra-rater reliability were assessed using weighted Cohen's kappa and Fleiss' kappa coefficients. Non-instrumental measures diagnostic performance was evaluated using receiver operating characteristic (ROC) curve analysis. Twenty-six of 113 patients (23%) exhibited an unsafe swallowing. Inter- and intra-rater agreement for DOSS classification was excellent across raters. EAT-10 and a composite clinical index derived from VC, VRC, and MPT showed the highest diagnostic accuracy with area under the curve values of 0.790 and 0.832, respectively. Other non-instrumental measures demonstrated lower discriminative performance. The DOSS showed an excellent reliability when applied to FEES in patients with ALS, supporting its use as a functional classification tool with direct nutritional and management implications. Non-instrumental measures should be interpreted with caution and confined to a triage role rather than diagnostic decision-making, particularly in light of the rapid progression of dysphagia in ALS.\n\nID: 41337107\nTitle: Detection of Amyotrophic Lateral Sclerosis with Computer Audition: An Impact Analysis of Different Speech Tasks.\nAbstract: We investigate the performance difference between training generic and task-based systems for the automatic detection of patients with Amyotrophic Lateral Sclerosis (ALS) from speech. We exploit the paralinguistic information embedded in their speech while producing the sustained vowel /a:/, repeating the syllables /da/-/da/ and /da/-/ba/ - separately -, reading a text passage, and describing a picture. While the former system consists of a single model, the latter is composed of five task-dedicated models, each one in charge of processing the speech samples corresponding to each task. We also analyse the performance of each task-dedicated model individually. We conduct our experiments on the novel, German-speaking AIMnd dataset. The obtained results - assessed in terms of the Unweighted Average Recall (UAR) - indicate that the task-based systems outperform the generic ones in two out of the four scenarios explored. The generic system only outperforms the task-based system in one scenario. In terms of the task-dedicated models, the SVClinear-based classifier exploiting the extended Geneva Minimalistic Acoustic Parameter Set (eGeMAPS) extracted from the sustained vowel /a:/ production task yields the best performance on the Test set with a UAR of 92%.\n\nID: 41082679\nTitle: International Survey of Practice Patterns of Speech-Language Pathologists Working With Patients With Amyotrophic Lateral Sclerosis.\nAbstract: Speech-language pathologists (SLPs) evaluate and treat swallowing and communication impairments in individuals with amyotrophic lateral sclerosis (ALS). Standardized clinical practice guidelines for the evaluation and management of bulbar dysfunction in ALS have not yet been established. This study aimed to describe current international practice patterns of SLPs evaluating and treating bulbar dysfunction in ALS. Significant variability in practice patterns will exist across SLPs working in different clinical settings with varied resources. A 26-item Qualtrics survey was electronically distributed to SLPs via e-mail, social media, and professional discussion boards. Data from 245 respondents across 20 countries and 32 states within the United States were collected, with the final analysis including 214 respondents. Most respondents practiced in metropolitan areas (69%) and worked in multidisciplinary ALS clinics (41%), outpatient clinics (16%), and home health settings (17%). Cranial nerve examination (91%), swallow trials (79%), speech intelligibility tasks (85%), and diadochokinetic speech rates (65%) were frequently included in evaluations. Although 81% of clinics had access to instrumental swallowing evaluations, 32% reported performing them in fewer than 25% of patients. Communication evaluations were offered directly by 58% of clinicians, while 26% referred to an outside SLP and 16% collaborated with device representatives. Most clinicians provided patient education on swallowing (87%) and oral health (83%). However, managed practice varied widely, revealing no standardized treatment that is routinely offered. Barriers to optimal ALS care included time constraints, relevant clinical training, timing of treatment, addressing psychosocial components of care, access to resources, interdisciplinary communication, and insurance coverage (United States only). Findings reveal little consensus on symptomatic bulbar management and intervention timing. Results emphasize the urgent need for the development of a standardized minimal data set to best guide the evaluation and management of bulbar dysfunction in ALS. https://doi.org/10.23641/asha.30249997.\n\nID: 40972658\nTitle: Real-time detection of spoken speech from unlabeled ECoG signals: a pilot study with an ALS participant.\nAbstract: Objective. Brain-computer interfaces hold significant promise for restoring communication in individuals with partial or complete loss of the ability to speak due to paralysis from amyotrophic lateral sclerosis (ALS), brainstem stroke, and other neurological disorders. Many of the approaches to speech decoding reported in the BCI literature have required time-aligned target representations to allow successful training-a major challenge when translating such approaches to people who have already lost their voice.Approach. In this pilot study, we made a first step toward scenarios in which no ground truth is available. We utilized a graph-based clustering approach to identify temporal segments of speech production from electrocorticographic (ECoG) signals alone. We then used the estimated speech segments to train a voice activity detection (VAD) model using only ECoG signals. We evaluated our approach using a leave-one-day-out cross-validation on open-loop recordings of a single dysarthric clinical trial participant living with ALS, and we compared the resulting performance to previous solutions trained with ground truth acoustic voice recordings.Main results. Our approach achieves a median timing error of around 530 ms with respect to the actual spoken speech. Embedded into a real-time BCI, our approach is capable of providing VAD results with a latency of only 10 ms.Significance. To the best of our knowledge, our results show for the first time that speech activity can be predicted purely from unlabeled ECoG signals, a crucial step toward individuals who cannot provide this information anymore due to their neurological condition, such as patients with locked-in syndrome.Clinical Trial Information. ClinicalTrials.gov, registration number NCT03567213.\n\nID: 40851280\nTitle: Automatically measured speech intelligibility models bulbar-specific disease severity and progression in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that leads to widespread motor deterioration, including significant motor speech impairments. Speech intelligibility is a crucial component of communication affected in ALS, requiring objective, scalable assessment methods as an indicator of disease progression and treatment efficacy. Objective: This study investigates whether speech and bulbar function in ALS could be evaluated and monitored utilizing an automated digital measure of speech intelligibility derived from naturalistic picture descriptions. Methods: Speech recordings from 44 patients living with ALS (plwALS) and 49 matched healthy controls (HC) were analyzed and processed utilizing an automated speech analysis pipeline to extract an intelligibility score. These were part of a cross-sectional and longitudinal study involving two assessments.\u00a0Results: The findings confirmed that speech intelligibility is significantly reduced in plwALS compared to HC. Those with bulbar-onset ALS have lower intelligibility than those with spinal-onset ALS, and the intelligibility of individuals with bulbar symptoms-regardless of the onset type-is lower than in plwALS without bulbar symptoms. Declining ALS-related speech scores correspond with worsening intelligibility in longitudinal assessments. Intelligibility correlates strongly with bulbar-specific clinical measures but not with global scores, highlighting its role in tracking bulbar progression. In some plwALS, we were able to demonstrate that automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring. Conclusion: Our findings highlight that automated speech intelligibility assessments can be a valuable marker to improve clinical monitoring and facilitate earlier intervention in ALS as a supplement to standard assessments.\n\nID: 40712472\nTitle: Mapping 74 years in acoustic analysis of voice disorders: A bibliometric review and future research directions.\nAbstract: This paper conducts a bibliometric analysis to identify and examine the strengths, gaps, and trends in research on acoustic voice assessment for voice disorders. A bibliometric analysis was performed on journal articles about voice disorders and acoustic voice assessment in English, Spanish, and Portuguese using seven indexed databases. The analyzed bibliometric parameters included publication year, authors, institutions, countries, journals, subject areas, and keywords. VOSviewer software was used for keyword co-occurrence analysis and authorships network analysis. The initial search yielded 6532 publications, with 1253 relevant papers after screening (1951-2024). Publications in acoustic voice assessment had 74 years of exponential growth (25 % published after 2021). The publishing journals covered 80 categories and subjects. Artificial Intelligence, though recent, was among the top journal subjects. Health conditions like dementia, Alzheimer's, Amyotrophic lateral sclerosis, and depression were underassessed compared to Parkinson's. The literature focused on four separate themes: physiology of voice-affecting conditions; speech acoustics for evaluating dysphonia; speech production measurements for treating voice disorders; machine learning integration for voice disorder assessment. Taking a wide view of acoustic voice assessment demonstrated research strengths and gaps-highlighting where it is used and not used-and the co-occurrence of various voice assessment topics. These insights reveal future opportunities to implement acoustic voice assessment.\n\nID: 40690785\nTitle: Exploring Methodological Decisions for Calculating the Minimally Detectable Change in Dysarthria: Reliability, Statistics, and Standard Error of Measurement.\nAbstract: The minimally detectable change (MDC), widely used in rehabilitation sciences to interpret changes in outcome measures, is calculated using a reliability method, reliability statistic, and standard error of measurement (SEM). This study examined how different methodological choices affect MDC thresholds of speech intelligibility in speakers with dysarthria. The goals of this study were to compare MDCs calculated using (a) three different reliability methods, (b) two different reliability statistics, and (c) three different SEM calculations. Recordings of the Speech Intelligibility Test from 200 speakers including speakers with amyotrophic lateral sclerosis (n = 16), Huntington's disease (n = 44), multiple sclerosis (n = 60), and Parkinson's disease (n = 40), along with healthy controls (n = 40), were drawn from two databases. Thirty inexperienced listeners completed two sessions, providing orthographic transcriptions of 20 speakers. MDCs of intelligibility were calculated using (a) three reliability methods (i.e., test-retest, split-half, and intrarater), (b) two reliability statistics (i.e., Pearson r and intraclass correlation coefficients [ICCs]), and (c) three different formulas for calculating the SEM. Kruskal-Wallis tests were used to assess the effects of reliability methods, statistics, and SEM calculations. Significant differences were found between the MDCs when using split-half and test-retest reliability, when using Pearson r and ICC, and when using two of the three SEM calculations. Results demonstrate that methodological decisions can impact MDCs of speech intelligibility in speakers with dysarthria, highlighting the need for specific, detailed reporting of methodology used to calculate MDCs in future work. Findings can provide methodological guidance for future studies and contextualize existing research on intelligibility changes.\n\nID: 40506548\nTitle: An instantaneous voice-synthesis neuroprosthesis.\nAbstract: Brain-computer interfaces (BCIs) have the potential to restore communication for people who have lost the ability to speak owing to a neurological disease or injury. BCIs have been used to translate the neural correlates of attempted speech into text1-3. However, text communication fails to capture the nuances of human speech, such as prosody and immediately hearing one's own voice. Here we demonstrate a brain-to-voice neuroprosthesis that instantaneously synthesizes voice with closed-loop audio feedback by decoding neural activity from 256 microelectrodes implanted into the ventral precentral gyrus of a man with amyotrophic lateral sclerosis and severe dysarthria. We overcame the challenge of lacking ground-truth speech for training the neural decoder and were able to accurately synthesize his voice. Along with phonemic content, we were also able to decode paralinguistic features from intracortical activity, enabling the participant to modulate his BCI-synthesized voice in real time to change intonation and sing short melodies. These results demonstrate the feasibility of enabling people with paralysis to speak intelligibly and expressively through a BCI.\n\nID: 40460399\nTitle: Construct Validity of the Amyotrophic Lateral Sclerosis Bulbar Dysfunction Index-Remote.\nAbstract: The Amyotrophic Lateral Sclerosis Bulbar Dysfunction Index-Remote (ALSBDI-R) is a clinician-administered tool designed to assess bulbar dysfunction remotely in patients with amyotrophic lateral sclerosis (ALS). This study aimed to evaluate the construct validity of the ALSBDI-R by examining its correlation with established clinical measures and its ability to discriminate among different bulbar disease severities. A total of 92 patients with ALS were recruited from two multidisciplinary clinics. Participants were assessed using the ALSBDI-R, the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R), the Center for Neurologic Study Bulbar Function Scale (CNS-BFS), the Sentence Intelligibility Test, and the Eating Assessment Tool (EAT-10). Construct validity was established through Spearman correlations and comparison of ALSBDI-R scores across bulbar severity groups (asymptomatic, mild, moderate, severe). Strong correlations were found between ALSBDI-R total scores and bulbar-specific measures such as ALSFRS-R bulbar subscore (r = -.85), CNS-BFS (r = .85), and EAT-10 (r = .77). The ALSBDI-R effectively discriminated between severity groups, supporting its construct validity. Severity bins were created based on median ALSBDI-R total scores for each group. The ALSBDI-R is a valid tool for remotely assessing bulbar dysfunction in patients with ALS. Despite several limitations, its ability to capture varying degrees of severity makes it valuable for clinical use and research, offering a standardized approach to monitor disease progression remotely.\n\nID: 40275673\nTitle: Everyday Communication Experiences of Persons With Amyotrophic Lateral Sclerosis and Their Caregivers: Implications for Novel Speech Interventions.\nAbstract: Speech intelligibility decline is a common in dysarthria secondary to amyotrophic lateral sclerosis (ALS). However, interventions that focus on improving speech may not be able to counteract decline as the disease progresses. Researchers have suggested interventions that help PALS's communication partners tune their speech perception systems to PALS's production. In the current study, we take a first step to establishing the need and enthusiasm for such interventions on the part of PALS and their caregivers (CPALS). PALS and CPALS recruited from the Greater Philadelphia chapter of the ALS association completed novel questionnaires probing their everyday speech communication and speech intervention experiences. Questions focused especially on changes in communication partners' ability to understand PALS' speech. Both quantitative and qualitative data were recorded. PALS (n\u2009=\u200921) and CPALS (n\u2009=\u200922) reported speech as a primary mode of communication despite declines in intelligibility. However, most also indicated variability in PALS's speech intelligibility depending on the communication partner, indicating that frequent communication partners were better able to understand PALS's speech. Both groups reported interest in interventions supporting speech intelligibility and were most interested in speech interventions that included PALS and CPALS together. PALS and especially CPALS in our study expressed interest in speech interventions that involved both parties. Thus, there is both a need for and a desire in the community for interactive speech interventions that support intelligibility. Additionally, our findings lend support to clinical approaches targeting frequent communication partners in addition to PALS.\n\nID: 39805247\nTitle: Thoracic paraspinal muscle concentric needle electrode jitter analysis in electrophysiological diagnosis of ALS.\nAbstract: Jitter analysis with concentric needle electrode of the thoracic 9 (T9) paraspinal muscle (PM), where the needle EMG examination at rest is difficult, was performed in both amyotrophic lateral sclerosis (ALS) patients and the controls. For the T9 PM, both upper limit for mean and individual mean consecutive difference (MCD) values and spike numbers were calculated according to jitter values of pairs from controls. In addition to the descriptive statistics, differences between two groups and T9 PM needle EMG and jitter analysis findings of patients were compared (p\u00a0=\u00a00.05). Mean MCD median values of T9 PM were 62.8 and 26.2\u00a0\u00b5s in patient and controls respectively. Upper limit of mean and individual MCDs for the T9 PM were determined as 36.95\u00a0\u03bcs, 57.95\u00a0\u03bcs respectively. The differences between controls and patients in terms of all jitter analysis parametres (p\u00a0<\u00a00.001) and the comparison of patients' T9 PM needle EMG and jitter analysis findings grading were statistically significant (p\u00a0=\u00a00.029). The T9 PM jitter analysis performed during routine EMG can be used to support the electrophysiological diagnosis of ALS in challenging cases and may contribute to minimizing the number of muscles examined. Furthermore, our study contributed to the T9 PM reference values for jitter analysis.\n\nID: 39779800\nTitle: Artificial intelligence empowered voice generation for amyotrophic lateral sclerosis patients.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease that can result in a progressive loss of speech due to bulbar dysfunction, which can have significant negative impact on the patient's mental well-being. Alternative Augmentative Communication (AAC) strategies based on synthetic voices have been shown to assist patients in maintaining communication and improving their Quality of Life (QoL). However, such synthetic voices are often perceived as impersonal and fail to capture the unique voice and identity of the patient. To tackle this issue, combining voice banking (VB) and artificial intelligence (AI) has emerged as a more natural communication strategy, enabling individuals to preserve their voice for use with AAC devices as needed. This involves recording speech samples to generate a synthetic voice closely resembling the individual's own. Despite the increasing interest in VB, there's a lack of clear strategies for its effective implementation in rapidly progressing diseases like ALS. Additionally, the perceptual quality of VB on patients with preserved speech, especially when offered early in the disease, remains poorly understood. In light of these challenges, this study aims to assess the effectiveness and the perceptual impact of AI-generated voices on ALS patients with preserved speech, utilizing a personalized voice synthesis system based on machine learning. The AI-generated patient-specific voice is achieved through voice recording, followed by fine-tuning using a Generative Adversarial Network for Efficient and High Fidelity Speech Synthesis (HiFi-GAN), resulting in a model capable of producing speech highly similar to the patient's own voice, with exceptional expressive and audio quality. By addressing these aspects, this study intends to offer valuable insights into the potential benefits and challenges of combining VB with AI voices to enhance communication support for ALS patients.\n\nID: 39694549\nTitle: [Analysis of clinical characteristics of amyotrophic lateral sclerosis patients initially diagnosed with abnormal laryngeal function].\nAbstract: Objective: To study the laryngeal functional characteristics of patients with amyotrophic lateral sclerosis (ALS)disease diagnosed at the voice clinic. Methods: A retrospective analysis(case series study) was conducted on the laryngeal functional characteristics of 7 patients [2 males, 5 females, age ranged from 43 to 76(60.85\u00b113.18)]with motor neuron disease who visited the voice clinic and were ultimately diagnosed by neurologists. The data included laryngostroboscopy, fiberoptic endoscopic examination of swallowing(FEES), acoustic analysis and laryngeal electromyography(LEMG). Descriptive methods were used for analysis. Results: \u2460There were 2 males and 5 females, with an average age of (60.85\u00b113.18) years. They had previously visited the otolaryngology department more than twice, visit frequency with an average of 3.57 and an average diagnosis time of 12.28 months. The main complaints of the patient at the time of treatment were voice change, dysphagia or vocal fatigue. \u2461LEMG: Among 7 cases, 4 cases demonstrated neurogenic damage, all of which were bilateral, and 3 cases showed normal findings on examination. Spontaneous potentials (SP) were present in three cases for more than 6 months, with the longest duration being 24 months. Three cases exhibited the coexistence of spontaneous potential and reinnervated motor unit potentials (MUPs), and two cases showed bundle tremor potential.\u2462Laryngostroboscopy revealed bilateral vocal fold asymmetry and glottic insufficiency in 7 cases, and decreased vocal cord movement in 4 cases, and vocal cord atrophy in 5 cases. FEES showed that 7 patients presented with mild to severe swallowing dysfunction, 3 cases had soft palate insufficiency and mild to severe food residues in the epiglottic valley and pyriform fossa. 1 case showed leakage and 1 case showed aspiration. Conclusions: Patients presenting with initial symptoms of abnormal laryngeal function should be vigilant for the possibility of motor neuron disease, especially when laryngostroboscopy reveals abnormal vocal fold movement and swallowing dysfunction. LEMG examination reveals bilateral neurogenic damage, prolonged spontaneous potential, coexistence of spontaneous potential and reinnervated MUPs, and the appearance of bundle tremor potential, which is beneficial for early detection of motor neuron disease. \u76ee\u7684\uff1a \u5206\u6790\u9996\u8bca\u55d3\u97f3\u79d1\u7684\u808c\u840e\u7f29\u4fa7\u7d22\u786c\u5316\uff08amyotrophic lateral sclerosis\uff0cALS\uff09\u60a3\u8005\u7684\u5589\u90e8\u75c7\u72b6\u3001\u4f53\u5f81\u548c\u5589\u808c\u7535\u56fe\u7279\u70b9\u3002 \u65b9\u6cd5\uff1a \u8be5\u75c5\u4f8b\u7cfb\u5217\u7814\u7a76\u5206\u67902021\u5e744\u6708\u81f32023\u5e744\u6708\u5728\u53a6\u95e8\u5927\u5b66\u9644\u5c5e\u4e2d\u5c71\u533b\u9662\u55d3\u97f3\u95e8\u8bca\u9996\u8bca\u3001\u6700\u7ec8\u786e\u8bcaALS\u76847\u4f8b\u60a3\u8005\uff3b\u7537\u60272\u4f8b\uff0c\u5973\u60275\u4f8b\uff1b\u5e74\u9f84\u4e3a43~76\uff0860.85\u00b113.18\uff09\u5c81\uff3d\u7684\u5589\u90e8\u75c7\u72b6\u3001\u4f53\u5f81\uff08\u9891\u95ea\u5589\u955c\u3001\u541e\u54bd\u5589\u955c\uff09\u3001\u58f0\u5b66\u8bc4\u4f30\u53ca\u5589\u808c\u7535\u56fe\u8d44\u6599\u3002\u91c7\u7528\u63cf\u8ff0\u6027\u65b9\u6cd5\u8fdb\u884c\u5206\u6790\u3002 \u7ed3\u679c\uff1a \u24607\u4f8b\u60a3\u8005\u65e2\u5f80\u5747\u5728\u8033\u9f3b\u54bd\u5589\u79d1\u5c31\u8bca2\u6b21\u4ee5\u4e0a\uff08\u4e2d\u4f4d\u6b21\u65703.57\u6b21\uff09\uff0c\u786e\u8bca\u65f6\u95f4\u4e3a12.28\u4e2a\u6708\u3002\u5c31\u8bca\u65f6\u4e3b\u8bc9\u4e3b\u8981\u4e3a\uff1a\u58f0\u97f3\u5636\u54d1\u3001\u53d1\u58f0\u8d39\u529b\u3001\u53d1\u58f0\u75b2\u52b3\u3001\u541e\u54bd\u5f02\u7269\u611f\u6216\u541e\u54bd\u56f0\u96be\u3001\u547c\u5438\u4e0d\u7545\u53ca\u8bf4\u8bdd\u542b\u7cca\u7b49\u3002\u2461\u5589\u808c\u7535\u56fe\uff1a7\u4f8b\u4e2d4\u4f8b\u63d0\u793a\u4e3a\u795e\u7ecf\u6e90\u6027\u635f\u5bb3\uff0c\u4e14\u5747\u4e3a\u53cc\u4fa7\uff0c3\u4f8b\u68c0\u67e5\u6b63\u5e38\uff1b3\u4f8b\u53d1\u73b0\u81ea\u53d1\u7535\u4f4d\u8005\u5747\u51fa\u73b0\u57286\u4e2a\u6708\u4ee5\u4e0a\uff0c\u6700\u957f\u8005\u8fbe24\u4e2a\u6708\uff1b3\u4f8b\u53d1\u73b0\u8fdb\u884c\u6027\u5931\u795e\u7ecf\u635f\u5bb3\u548c\u6162\u6027\u518d\u751f\u5e76\u5b58\uff0c2\u4f8b\u51fa\u73b0\u675f\u98a4\u7535\u4f4d\u3002\u2462\u9891\u95ea\u5589\u955c\uff1a7\u4f8b\u60a3\u8005\u5747\u51fa\u73b0\u53cc\u4fa7\u58f0\u5e26\u8fd0\u52a8\u4e0d\u5bf9\u79f0\u548c\u58f0\u95e8\u95ed\u5408\u4e0d\u5168\uff084\u4f8b\u5782\u76f4\u9762\uff0c3\u4f8b\u6c34\u5e73\u9762\uff09\uff0c5\u4f8b\u58f0\u5e26\u677e\u5f1b\uff0c3\u4f8b\u53cc\u4fa7\u58f0\u5e26\u8fd0\u52a8\u51cf\u5f31\uff0c1\u4f8b\u5355\u4fa7\u58f0\u5e26\u8fd0\u52a8\u51cf\u5f31\u3002\u541e\u54bd\u5589\u955c\uff1a7\u4f8b\u60a3\u8005\u5747\u663e\u793a\u6709\u8f7b-\u91cd\u5ea6\u4e0d\u7b49\u7684\u541e\u54bd\u529f\u80fd\u969c\u788d\uff0c3\u4f8b\u60a3\u8005\u8f6f\u816d\u95ed\u5408\u4e0d\u5168\uff0c\u8fdb\u98df\u540e\u4f1a\u538c\u8c37\u53ca\u68a8\u72b6\u7a9d\u5747\u6709\u8f7b\u5ea6-\u91cd\u5ea6\u4e0d\u7b49\u7684\u98df\u7269\u6b8b\u7559\uff0c1\u4f8b\u89c1\u6e17\u6f0f\uff0c1\u4f8b\u89c1\u8bef\u5438\u3002 \u7ed3\u8bba\uff1a \u9996\u53d1\u75c7\u72b6\u4e3a\u5589\u529f\u80fd\u5f02\u5e38\u7684\u60a3\u8005\uff0c\u5f53\u9891\u95ea\u5589\u955c\u53d1\u73b0\u58f0\u5e26\u8fd0\u52a8\u529f\u80fd\u5f02\u5e38\u7279\u522b\u662f\u58f0\u95e8\u95ed\u5408\u4e0d\u5168\u540c\u65f6\u4f34\u6709\u541e\u54bd\u5589\u955c\u4e0b\u541e\u54bd\u529f\u80fd\u5f02\u5e38\u65f6\uff0c\u9700\u8b66\u60d5ALS\u7684\u53ef\u80fd\uff0c\u5589\u808c\u7535\u56fe\u68c0\u67e5\u53d1\u73b0\u53cc\u4fa7\u795e\u7ecf\u6e90\u6027\u635f\u5bb3\u3001\u81ea\u53d1\u7535\u4f4d\u957f\u65f6\u95f4\u6301\u7eed\u5b58\u5728\u3001\u81ea\u53d1\u7535\u4f4d\u548c\u5bbd\u5927\u8fd0\u52a8\u5355\u4f4d\u7535\u4f4d\uff08motor unit potential\uff0cMUP\uff09\u5e76\u5b58\u4ee5\u53ca\u675f\u98a4\u7535\u4f4d\u7684\u51fa\u73b0\uff0c\u6709\u52a9\u4e8e\u65e9\u671f\u53d1\u73b0\u8bca\u65adALS\u3002.\n\nID: 39679928\nTitle: Inter-speaker acoustic differences of sustained vowels at varied dysarthria severities for amyotrophic lateral sclerosis.\nAbstract: We study inter-speaker acoustic differences during sustained vowel utterances at varied severities of Amyotrophic Lateral Sclerosis-induced dysarthria. Among source attributes, jitter and standard deviation of fundamental frequency exhibit enhanced inter-speaker differences among patients than healthy controls (HCs) at all severity levels. Though inter-speaker differences in vocal tract filter attributes at most severity levels are higher than those among HCs for close vowels /i/ and /u/, these are comparable with or lower than those among HCs for the relatively more open vowels /a/ and /o/. The differences typically increase with severity except for a few parameters for /a/ and /i/.\n\nID: 39606178\nTitle: Corrigendum: An automatic measure for speech intelligibility in dysarthrias-validation across multiple languages and neurological disorders.\nAbstract: [This corrects the article DOI: 10.3389/fdgth.2024.1440986.].\n\nID: 39595845\nTitle: Voice Assessment in Patients with Amyotrophic Lateral Sclerosis: An Exploratory Study on Associations with Bulbar and Respiratory Function.\nAbstract: Speech production is a possible way to monitor bulbar and respiratory functions in patients with amyotrophic lateral sclerosis (ALS). Moreover, the emergence of smartphone-based data collection offers a promising approach to reduce frequent hospital visits and enhance patient outcomes. Here, we studied the relationship between bulbar and respiratory functions with voice characteristics of ALS patients, alongside a speech therapist's evaluation, at the convenience of using a simple smartphone. For voice assessment, we considered a speech therapist's standardized tool-consensus auditory-perceptual evaluation of voice (CAPE-V); and an acoustic analysis toolbox. The bulbar sub-score of the revised ALS functional rating scale (ALSFRS-R) was used, and pulmonary function measurements included forced vital capacity (FVC%), maximum expiratory pressure (MEP%), and maximum inspiratory pressure (MIP%). Correlation coefficients and both linear and logistic regression models were applied. A total of 27 ALS patients (12 males; 61 years mean age; 28 months median disease duration) were included. Patients with significant bulbar dysfunction revealed greater CAPE-V scores in overall severity, roughness, strain, pitch, and loudness. They also presented slower speaking rates, longer pauses, and higher jitter values in acoustic analysis (all p < 0.05). The CAPE-V's overall severity and sub-scores for pitch and loudness demonstrated significant correlations with MIP% and MEP% (all p < 0.05). In contrast, acoustic metrics (speaking rate, absolute energy, shimmer, and harmonic-to-noise ratio) significantly correlated with FVC% (all p < 0.05). The results provide supporting evidence for the use of smartphone-based recordings in ALS patients for CAPE-V and acoustic analysis as reliable correlates of bulbar and respiratory function.\n\nID: 39409405\nTitle: Brain Function, Learning, and Role of Feedback in Complete Paralysis.\nAbstract: The determinants and driving forces of communication abilities in the locked-in state are poorly understood so far. Results from an experimental-clinical study on a completely paralyzed person involved in communication sessions after the implantation of a microelectrode array were retrospectively analyzed. The aim was to focus on the prerequisites and determinants for learning to control a brain-computer interface for communication in paralysis. A comparative examination of the communication results with the current literature was carried out in light of an ideomotor theory of thinking. We speculate that novel skill learning took place and that several aspects of the wording of sentences during the communication sessions reflect preserved cognitive and conscious processing. We also present some speculations on the operant learning procedure used for communication, which argues for the reformulation of the previously postulated hypothesis of the extinction of response planning and goal-directed ideas in the completely locked-in state. We highlight the importance of feedback and reinforcement in the thought-action-consequence associative chain necessary to maintain purposeful communication. Finally, we underline the necessity to consider the psychosocial context of patients and the duration of complete immobilization as determinants of the 'extinction of thinking' theory and to identify the actual barriers preventing communication in these patients.\n\nID: 39393594\nTitle: A systematic review of the quantitative markers of speech and language of the frontotemporal degeneration spectrum and their potential for cross-linguistic implementation.\nAbstract: Frontotemporal dementia (FTD) is a neurodegenerative disease spectrum with an urgent need for reliable biomarkers for early diagnosis and monitoring. Speech and language changes occur in the early stages of FTD and offer a potential non-invasive, early, and accessible diagnostic tool. The use of speech and language markers in this disease spectrum is limited by the fact that most studies investigate English-speaking patients. This systematic review examines the literature on psychoacoustic and linguistic features of speech that occur across the FTD spectrum across as many different languages as possible. 76 papers were identified that investigate psychoacoustic and linguistic markers in discursive speech. 75\u202f% of these papers studied English-speaking patients. The most generalizable features found across different languages, are speech rate, articulation rate, pause frequency, total pause duration, noun-verb ratio, and total number of nouns. While there are clear interlinguistic differences across patient groups, the results show promise for implementation of cross-linguistic markers of speech and language across the FTD spectrum particularly for psychoacoustic features.\n\nID: 39138039\nTitle: Exploring the Impact of Amyotrophic Lateral Sclerosis on Otolaryngological Functions.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive degeneration of upper and lower motor neurons at the spinal or bulbar level. We aim to describe the most frequent otolaryngology (ORL) complaints and voice disturbances in patients with bulbar onset ALS. Retrospective cohort study. Single-center study with combined ORL and ALS clinic evaluation. Patients with a confirmed diagnosis of ALS following an ORL visit and who underwent comprehensive voice assessments between January 2021 and January 2023. Objective voice assessments. Glottal functional index (GFI), voice handicap index (VHI), reflux system index (RSI), and voice quality characteristics such as shimmer, jitter, maximum phonation time (MPT), and other essential parameters were assessed. One hundred and thirty-three patients (age 62.17\u00a0\u00b1\u00a010.79, 54.48% female) were included. Three patients were referred from the ORL department to the ALS clinic. The most frequent symptoms were; dysphagia, dysarthria, facial weakness, pseudobulbar affect, and sialorrhea. The mean of forced vital capacity was 59.85%, EAT-10 15.91\u00a0\u00b1\u00a011.66, RSI 25.84\u00a0\u00b1\u00a09.03, GFI 14.12\u00a0\u00b1\u00a05.58, VHI-10 42.81\u00a0\u00b1\u00a034.94, MPT 15.22\u00a0s\u00a0\u00b1\u00a08.06. Many patients reported voice impairments mainly related to spastic dysarthria and the combination of lower and upper motor neuron dysarthria, hypernasality, reduced verbal expression, and articulatory accuracy. Shimmer was increased to 8.46%\u00a0\u00b1\u00a07.20, and jitter to 2.26%\u00a0\u00b1\u00a01.39. Based on our cohort, this population with bulbar onset ALS has a higher frequency of voice disturbance characterized by hypernasality, spastic dysarthria, and reduced verbal expression. Level 3.\n\nID: 39126786\nTitle: Multimodal speech biomarkers for remote monitoring of ALS disease progression.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that severely impacts affected persons' speech and motor functions, yet early detection and tracking of disease progression remain challenging. The current gold standard for monitoring ALS progression, the ALS functional rating scale - revised (ALSFRS-R), is based on subjective ratings of symptom severity, and may not capture subtle but clinically meaningful changes due to a lack of granularity. Multimodal speech measures which can be automatically collected from patients in a remote fashion allow us to bridge this gap because they are continuous-valued and therefore, potentially more granular at capturing disease progression. Here we investigate the responsiveness and sensitivity of multimodal speech measures in persons with ALS (pALS) collected via a remote patient monitoring platform in an effort to quantify how long it takes to detect a clinically-meaningful change associated with disease progression. We recorded audio and video from 278 participants and automatically extracted multimodal speech biomarkers (acoustic, orofacial, linguistic) from the data. We find that the timing alignment of pALS speech relative to a canonical elicitation of the same prompt and the number of words used to describe a picture are the most responsive measures at detecting such change in both pALS with bulbar (n = 36) and non-bulbar onset (n = 107). Interestingly, the responsiveness of these measures is stable even at small sample sizes. We further found that certain speech measures are sensitive enough to track bulbar decline even when there is no patient-reported clinical change, i.e. the ALSFRS-R speech score remains unchanged at 3 out of a total possible score of 4. The findings of this study have the potential to facilitate improved, accelerated and cost-effective clinical trials and care.\n\nID: 41375893\nTitle: Rehabilitation in Amyotrophic Lateral Sclerosis: Recommendations for Clinical Practice and Further Research.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative condition characterized by the degeneration of upper and lower motor neurons. This degeneration leads to a gradual muscle weakness, dysarthria, dysphagia, respiratory insufficiency, and, in some patients, alterations in cognitive and behavioral performance. Regardless of advancements made in pharmacological and gene-targeted interventions, a definitive curative treatment remains elusive. Consequently, rehabilitation plays a pivotal role in preserving autonomy, participation, and overall quality of life. This review outlines the current evidence and clinical approaches related to multidisciplinary rehabilitation in ALS. It covers physical and occupational therapy, respiratory, speech and language, psychological, and palliative care domains. Evidence supports moderate tailored exercise programs, early respiratory therapy, and structured management of mobility deficits, spasticity, pain, dysphagia, and communication impairments as key elements of symptomatic treatment. Psychological and social support, which includes the involvement of caregivers and relatives, enhances emotional well-being and coping resilience. Even with progressive development of gene-targeted and disease-modifying therapies, rehabilitation will stay relevant for maintaining long-term motor function. This review highlights the need for standardized, evidence-based rehabilitation protocols and intensified neurorehabilitation research to strengthen clinical outcomes and quality of life as key therapeutic goals in ALS management.\n\nID: 38064644\nTitle: A Fine-Grained Temporal Analysis of Multimodal Oral Diadochokinetic Performance to Assess Speech Impairment in Amyotrophic Lateral Sclerosis.\nAbstract: This study used a semiautomated fine-grained temporal analysis to extract features of temporal oral diadochokinetic (DDK) performance across multiple modalities and tasks, from neurologically healthy and impaired individuals secondary to amyotrophic lateral sclerosis (ALS). The aims were to (a) delineate temporal oral DDK deficits relating to the neuromotor pathology of ALS and (b) identify the optimal task-feature combinations to detect speech impairment in ALS. Mandibular myoelectric, kinematic, and acoustic data were acquired from 13 individuals with ALS and 10 healthy controls producing three alternating motion rate tasks and one sequential motion rate task. Twenty-seven features were extracted from the multimodal data, characterizing three temporal constructs: duration/rate, variability, and coordination. The disease impacts on these features were assessed across tasks, and the task eliciting the greatest disease-related change was identified for each feature. Such \"optimal\" task-feature combinations were fed into logistic regression to differentiate individuals with ALS from healthy controls. Temporal deficits in ALS were characterized by (a) increased duration and variability and reduced coordination of jaw muscle activities, (b) increased duration and variability and altered temporal symmetry of jaw velocity profile, (c) increased muscle-burst-to-peak-velocity duration, and (d) increased motion-to-voice onset duration. These temporal features were differentially affected across tasks. The optimal task-feature combinations, which were further clustered into three composite factors reflecting temporal variability, coarser-grained duration, and finer-grained duration, differentiated ALS from controls with an F1 score of 0.86 (precision = 1.00, recall = 0.75). Temporal oral DDK deficits are likely attributed to a hierarchy of interrelated neurophysiological and biomechanical factors associated with the neuromotor pathology of ALS. These deficits, as assessed crossmodally, provide previously unavailable insights into the multifaceted timing impairment of oromotor performance in ALS. The optimal task-feature combinations targeting these deficits show promise as quantitative markers for (early) detection of speech impairment in ALS.\n\nID: 35136957\nTitle: Different saccadic profile in bulbar versus spinal-onset amyotrophic lateral sclerosis.\nAbstract: Two clinical phenotypes characterize the onset of amyotrophic lateral sclerosis (ALS): the spinal variant, with symptoms beginning in the limbs, and the bulbar variant, affecting firstly speech and swallowing. The two variants show some distinct features in the histopathology, localization and prognosis, but to which extent they really differ clinically and pathologically remains to be clarified. Recent neuropathological and neuroimaging studies have suggested a broader spreading of the neurodegenerative process in ALS, extending beyond the motor areas, toward other cortical and deep grey matter regions, many of which are involved in visual processing and saccadic control. Indeed, a wide range of eye movement deficits have been reported in ALS, but they have never been used to distinguish the two ALS variants. Since quantifying eye movements is a very sensitive and specific method for the study of brain networks, we compared different saccadic and visual search behaviours across spinal ALS patients (n = 12), bulbar ALS patients (n = 6) and healthy control subjects (n = 13), along with cognitive and MRI measures, with the aim to define more accurately the two patients subgroups and possibly clarify a different underlying neural impairment. We found separate profiles of visually-guided saccades between spinal (short saccades) and bulbar (slow saccades) ALS, which could result from the pathologic involvement of different pathways. We suggest an early involvement of the parieto-collicular-cerebellar network in spinal ALS and the fronto-brainstem circuit in bulbar ALS. Overall, our data confirm the diagnostic value of the eye movements analysis in ALS and add new insight on the involved neural networks.\n\nID: 34717271\nTitle: Primary progressive aphasias associated with C9orf72 expansions: Another side of the story.\nAbstract: C9orf72 repeat expansions are rarely associated with primary progressive aphasias (PPA). In-depth characterization of the linguistic deficits, and the underlying patterns of grey-matter atrophy in PPA associated with the C9orf72 expansions (PPA-C9orf72) are currently lacking. In this study, we comprehensively analyzed a unique series of 16 patients affected by PPA-C9orf72. Eleven patients were issued from two independent French and Finnish cohorts, and five were identified by means of literature review. Voxel-based morphometry (VBM) studies were performed on three of them. This study depicts the spectrum of C9orf72-related aphasic phenotypes, and illustrates their linguistic presentation. The non-fluent/agrammatic variant was the most frequent phenotype in our series (9/16 patients, 56%), with apraxia of speech being the main defining feature. Left frontal lobe atrophy was present in these subjects, peaking in inferior frontal gyrus. Three patients (19%) showed the semantic variant, with progression of atrophy in temporo-polar regions, later involving orbitofrontal cortex. Anterior temporal lobe dysfunction was also particularly relevant in two patients (12.5%) with mixed forms of PPA. Lastly, two patients (12.5%) had unclassifiable PPA with predominating word-finding difficulties. No PPA-C9orf72 patients in our series fulfilled the criteria of the logopenic variant. Importantly, this study underlines the role of C9orf72 mutation in the disruption of the most anterior parts of the language network, including prefrontal and temporo-polar areas. It provides guidelines for C9orf72 testing in PPA patients, with important clinical impact as gene-specific therapies are upcoming.\n\nID: 33980708\nTitle: Primary Progressive Aphasia Associated With GRN Mutations: New Insights Into the Nonamyloid Logopenic Variant.\nAbstract: To determine relative frequencies and linguistic profiles of primary progressive aphasia (PPA) variants associated with GRN (progranulin) mutations and to study their neuroanatomic correlates. Patients with PPA carrying GRN mutations (PPA-GRN) were selected among a national prospective research cohort of 1,696 patients with frontotemporal dementia, including 235 patients with PPA. All patients with amyloid-positive CSF biomarkers were excluded. In this cross-sectional study, speech/language and cognitive profiles were characterized with standardized evaluations, and gray matter (GM) atrophy patterns using voxel-based morphometry. Comparisons were performed with controls and patients with sporadic PPA. Among the 235 patients with PPA, 45 (19%) carried GRN mutations, and we studied 32 of these. We showed that logopenic PPA (lvPPA) was the most frequent linguistic variant (n = 13, 41%), followed by nonfluent/agrammatic (nfvPPA; n = 9, 28%) and mixed forms (n = 8, 25%). Semantic variant was rather rare (n = 2, 6%). Patients with lvPPA, qualified as nonamyloid lvPPA, presented canonical logopenic deficit. Seven of 13 had a pure form; 6 showed subtle additional linguistic deficits not fitting criteria for mixed PPA and hence were labeled as logopenic-spectrum variant. GM atrophy involved primarily left posterior temporal gyrus, mirroring neuroanatomic changes of amyloid-positive-lvPPA. Patients with nfvPPA presented agrammatism (89%) rather than apraxia of speech (11%). This study shows that the most frequent PPA variant associated with GRN mutations is nonamyloid lvPPA, preceding nfvPPA and mixed forms, and illustrates that the language network may be affected at different levels. GRN testing is indicated for patients with PPA, whether familial or sporadic. This finding is important for upcoming GRN gene-specific therapies.\n\nID: 33808458\nTitle: Cognitive and Behavioral Manifestations in ALS: Beyond Motor System Involvement.\nAbstract: Amyotrophic lateral sclerosis (ALS) has long been considered to be a purely motor disorder. However, it has become apparent that many ALS patients develop cognitive and behavioral manifestations similar to frontotemporal dementia and the term amyotrophic lateral sclerosis-frontotemporal spectrum disorder (ALS-FTSD) is now used in these circumstances. This review is intended to be an overview of the cognitive and behavioral manifestations commonly encountered in ALS patients with the goal of improving case-oriented management in clinical practice. We introduce the principal ALS-FTSD subtypes and comment on their principal clinical manifestations, neuroimaging findings, neuropathological and genetic background, and summarize available therapeutic options. Diagnostic criteria for ALS-FTSD create distinct categories based on the type of neuropsychological manifestations, i.e., changes in behavior, impaired social cognition, executive dysfunction, and language or memory impairment. Cognitive impairment is found in up to 65%, while frank dementia affects about 15% of ALS patients. ALS motor and cognitive manifestations can worsen in parallel, becoming more pronounced when bulbar functions (affecting speech, swallowing, and salivation) are involved. Dementia can precede or develop after the appearance of motor symptoms. ALS-FTSD patients have a worse prognosis and shorter survival rates than patients with ALS or frontotemporal dementia alone. Important negative prognostic factors are behavioral and personality changes. From the clinician's perspective, there are five major distinguishable ALS-FTSD subtypes: ALS with cognitive impairment, ALS with behavioral impairment, ALS with combined cognitive and behavioral impairment, fully developed frontotemporal dementia in combination with ALS, and comorbid ALS and Alzheimer's disease. Although the most consistent ALS and ALS-FTSD pathology is a disturbance in transactive response DNA binding protein 43 kDa (TDP-43) metabolism, alterations in microtubule-associated tau protein metabolism have also been observed in ALS-FTSD. Early detection and careful monitoring of cognitive deficits in ALS are crucial for patient and caregiver support and enable personalized management of individual patient needs.\n\nID: 31629403\nTitle: Comparative assessment and monitoring of deterioration of articulatory organs using subjective and objective tools among patients with amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal degenerative disease of a rapid course. In 25% of ALS sufferers, speech disorders occur as prodromal symptoms of the disease. Impaired communication affects physical health and has a negative impact on mental and emotional condition. In this study, we assessed which domains of speech are particularly affected in ALS. Subsequently, we estimated possible correlations between the ALS patients' subjective perception of their speech quality and an objective assessment of the speech organs carried out by an expert. The study group consisted of 63 patients with sporadic ALS. The patients were examined for articulatory functions by means of Voice Handicap Index (VHI) and the Frenchay Dysarthria Assessment (FDA). On the basis of the VHI scores, the entire cohort was divided into 2 groups: group I (40 subjects) with mild speech impairment, and group II (23 subjects) displaying moderate and profound speech deficits. In an early phase of ALS, changes were typically reported in the tongue, lips and soft palate. The FDA and VHI-based measurements revealed a high, positive correlation between the objective and subjective evaluation of articulation quality. Deterioration of the articulatory organs resulted in the reduction of social, physical and emotional functioning. The highly positive correlation between the VHI and FDA scales seems to indicate that the VHI questionnaire may be a reliable, self-contained tool for monitoring the course and progression of speech disorders in ALS.

Objective digital biomarkers, particularly those derived from acoustic and biomechanical analyses, demonstrate superior sensitivity compared to standard clinical ratings for capturing early disease progression. Speech rate, vowel acoustics, and articulatory precision are identified as sensitive metrics for the detection of subclinical bulbar motor neuron degeneration.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic lateral sclerosis, though primarily recognized for motor neuron degeneration, presents with non-motor and subtle bulbar manifestations that often precede definitive diagnosis. The literature confirms that in 25% of ALS sufferers, speech disorders occur as prodromal symptoms of the disease. Consequently, there is an urgent need to leverage digital technology to identify these latent changes. As one study notes, speech rate appears to decline significantly before the diagnosis of ALS is confirmed. The physiological basis for these alterations is supported by neuroimaging, which indicates that reduced speaking and articulation rates were associated with thinning in both oral motor cortices. Furthermore, the granularity afforded by digital tools allows for the identification of changes before they reach clinical thresholds, as automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Voice serves as a latent, multimodal biomarker reflecting neurological, cardiopulmonary, and psychological states.\n*   Automated segmentation algorithms can now identify syllable and phoneme positions during oral diadochokinesis with over 90% accuracy, providing a basis for objective monitoring.\n*   Biomechanical voice analysis captures physiologically meaningful alterations in vocal fold function, offering complementary information that transcends traditional clinical diagnostic labels.\n*   Changes in speech and swallowing function can be monitored remotely using smartphone applications, potentially reducing the need for frequent clinical hospital visits.\n*   There is a significant need for better standardized tools, as current outcome measurements for speech and swallow are deemed clinically meaningful by only a minority of practitioners.\n*   Vowel acoustic features (e.g., Formant Centralization Ratio) provide insight into the shared brainstem neuromotor substrate of both speech and swallowing.\n*   Research confirms the existence of coherent vocal profiles across patients that do not strictly align with existing clinical diagnostic categories.\n*   Early intervention protocols are limited by current guideline gaps, underscoring the necessity of individual-level predictive modeling.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

However, detection can be confounded due to factors like fatigue and testing anxiety. Cumulus neuroscience developed NeuLogiq(R), a multi-modal neurocognitive platform that can be used in clinic or at home, providing an ecologically valid measure of cognition. This study examined the feasibility and usability of NeuLogiq in plwALS, plwFTD, and controls, and compared performance on gold standard neuropsychological assessments with corresponding NeuLogiq digital assessments. Over 8 months, plwALS (n\u2009=\u200911), plwFTD (n\u2009=\u20097), and matched healthy controls (n\u2009=\u200910) completed longitudinal full neuropsychological assessment, as well as three 25-minute NeuLogiq Platform sessions every 2 weeks in their homes. Participants adhered well to the study schedule, conducting over 32/54 sessions on average. All groups rated usability in the 'good' or 'excellent' range and had\u2009>\u200980% complete data. Baseline group differences were detectable on both NeuLogiq digital assessments and benchmark neuropsychological assessments of similar cognitive domains. Longitudinal mixed effects models found that the ALS group showed decline on NeuLogiq measures of emotion recognition and speech fluency. These findings suggest that the NeuLogiq platform is feasible and usable for plwALS and plwFTD, and can identify cognitive deficits to a similar extent as benchmark assessments over time."

In this study, we reconstruct the developmental trajectory of cultured cortical networks derived from SOD1G93A mouse embryos using a multimodal approach, by combining morphometric, electrophysiological, pharmacological, molecular, computational, and machine-learning techniques. We prove that ALS neurons fail to acquire mature polarization and connectivity, displaying a transient phase of hyperexcitability that precedes a progressive collapse of network organization. Astrocytic dysfunction emerges early and impairs synchronization, establishing a causal link between glial dysfunction and neuronal instability. The analysis of synaptic transmission reveals an excitatory bias followed by maladaptive inhibitory recruitment and GABA/glutamate co-release, causing fragmented and inefficient network topologies. Finally, in silico modelling identified deficient intrinsic adaptation as a key driver of hyperexcitability. Together, our findings position ALS as a developmentally rooted disorder of cultured cortical network homeostasis, driven by glial, synaptic, and intrinsic adaptation failures. By demonstrating that cortical dysfunction is embedded before degeneration, this work provides a unifying framework connecting early network instability to disease progression and establishes electrophysiological network signatures, detected by machine learning classifiers, as candidate biomarkers for early diagnosis and therapeutic screening."

We included observational studies that applied sEMG to individuals diagnosed with ALS, with or without comparison to healthy controls, and without restrictions on publication year. The analyses included signals recorded at rest and during voluntary contractions, with or without the use of biofeedback. Most studies employed conventional or high-density surface electrodes, with sampling frequencies ranging from 500 Hz to 3000 Hz. The results showed that the primary parameters assessed were muscle fatigue, fasciculation patterns, the number of motor units (MUNE/MUNIX), motor unit firing rates, and signal complexity. These parameters demonstrated sensitivity to disease progression and may contribute to early diagnosis, phenotypic stratification, and functional monitoring of ALS. Additionally, the studies highlighted the increasing use of advanced computational approaches, such as machine learning, for feature extraction and automated classification. In conclusion, sEMG is a promising tool for functional assessment in ALS, with the potential to improve diagnostic accuracy and support new therapeutic strategies based on electrophysiological biomarkers. However, despite technological advances, the included studies displayed substantial methodological heterogeneity and limited protocol standardization. Integration with other neurophysiological modalities also remains underexplored, despite its significant clinical potential."

The primary aim of this translational pilot study was to identify a disease-specific, TDP-43-related, gene-microRNA (miRNA) signature in peripheral blood mononuclear cells (PBMCs) of ALS patients with potential diagnostic value. To this end, we first identified differentially expressed disease-specific genes (dsDEGs) using a TDP-43-based rat model of ALS, generated by stereotaxic infusion of full-length (FL) TAR DNA-binding protein 43 (TDP-43) into the motor cortex. Transcriptomic profiling of the motor cortex revealed candidate dsDEGs, which were subsequently validated by RT-qPCR in motor cortex, spinal cord, and PBMCs from the same animals. To assess translational relevance, expression levels of these dsDEGs were analyzed in PBMCs from early- to mid-stage ALS patients and matched healthy controls, while disease specificity was evaluated using Parkinson's disease (PD) samples. In parallel, conserved miRNAs predicted to target the identified dsDEGs were examined in both rat and human PBMCs. Five dsDEGs, Mctp1, Penk, Mt2A, Drd1, and Rasgrp2, were consistently dysregulated across central and peripheral tissues in the TDP-43 rat model. RT-qPCR analysis of human PBMCs confirmed significant and selective dysregulation of these genes in ALS, but not in PD, supporting disease specificity. Moreover, exposure of human neuroblastoma cells and healthy PBMCs to TDP-43 recapitulated the ALS-like expression changes. Computational and experimental analyses identified seven conserved miRNAs targeting these dsDEGs, of which four were significantly downregulated in ALS PBMCs, supporting a coordinated regulatory network. Receiver operating characteristic (ROC) analyses demonstrated strong discriminative performance for both the gene signature (AUC 0.87-1.00) and the associated miRNAs (AUC 0.95-1.00).

The absence of specific diagnostic biomarkers leads to diagnostic delays, hindering early intervention and management. This review provides a critical appraisal of fluid-based biomarkers for ALS across multiple sources-cerebrospinal fluid (CSF), blood, urine, saliva, and tears-with emphasis on their diagnostic and prognostic potential, limitations, and readiness for clinical translation. While neurofilaments (NfL, pNfH) are well-established as sensitive indicators of neuroaxonal injury and are increasingly used as prognostic and pharmacodynamic markers in clinical trials, they lack disease specificity. Biomarkers reflecting ALS-specific pathology, such as TDP-43 species and C9orf72 dipeptide repeat proteins (DPRs), show promise but remain in early validation stages with limited multicenter data. Emerging markers from non-invasive sources (urine p75ECD, salivary chromogranin A, tear metabolomics) offer potential for repeated sampling but require rigorous external validation before clinical adoption. To address current gaps, we introduce a standardized evidence grading framework (Tier 1-3) and a comprehensive reporting template for biomarker studies, including explicit performance metrics (AUC, sensitivity, specificity, confidence intervals) and validation status. We also propose minimum reporting standards for study design, pre-analytical variables, and statistical rigor, modeled on REMARK guidelines. A roadmap for biomarker validation and a cross-fluid comparison matrix are provided to guide future research. Despite considerable progress, significant challenges remain, including biological heterogeneity, pre-analytical variability, and insufficient external validation. Future efforts should prioritize multicenter prospective studies, assay harmonization, ethical frameworks for early diagnosis, and integration of emerging technologies such as artificial intelligence and digital twins. Fluid-based biomarkers, while not yet replacing clinical evaluation, are essential tools for accelerating drug development, enabling patient stratification, and moving toward personalized medicine in ALS."

Through logistic regression, random forest models, receiver operating characteristic (ROC) curve analysis, and SHAP interpretability analysis, the predictive abilities and clinical significance of each candidate indicator were screened and evaluated. Notable disparities were detected in age, leukocyte count, monocyte levels, glycated haemoglobin A1c (HbA1c), and haemoglobin glycation index (HGI) between the control and ALS groups (all P < 0.05). Logistic regression analysis revealed that age (OR = 1.114) and monocyte (OR = 3.174) were risk factors for ALS, while leukocyte (OR = 0.533) and HbA1c (OR = 0.069) were protective factors. The random forest algorithm, ranked by decreasing importance, showed that leukocyte, HGI, monocyte, and HbA1c level all influenced ALS. Using these indicators to predict ALS resulted in a false-positive rate of 18% and a false-negative rate of 6%. ROC curve analysis indicated that the combined use of leukocyte, monocyte, HbA1c level, and HGI provided the highest diagnostic value for ALS (AUC = 0.774), which was higher than that of any individual indicator (all P < 0.05).

This study aimed to investigate the relationship between clinical dysphagia assessment tools (EAT-10, GUSS, RSST, and sialorrhea severity) and videofluoroscopic swallowing study (VFSS) findings in patients with ALS. Materials and Methods: This retrospective observational study included 60 patients with ALS classified as spinal-onset (n = 38) or bulbar-onset (n = 22). Relationships between clinical assessments and VFSS findings were analysed using Spearman correlation analysis. Exploratory multivariable regression and receiver operating characteristic (ROC) analyses were performed to evaluate associations and aspiration risk discrimination. Results: Strong negative correlations were observed between PAS-Liquid and RSST and GUSS scores, whereas EAT-10 showed a strong positive correlation (all p < 0.001). ROC analyses demonstrated good discriminative ability for aspiration risk for GUSS (AUC = 0.89), RSST (AUC = 0.88), and EAT-10 (AUC = 0.82). Patients with bulbar-onset ALS demonstrated higher penetration-aspiration severity and lower functional oral intake. Conclusions: Clinical dysphagia assessment tools showed significant associations with instrumental swallowing findings in ALS. GUSS and RSST demonstrated good discriminative ability for aspiration risk and may be clinically useful bedside screening tools. However, instrumental swallowing assessment remains essential whenever feasible."

Recent work has demonstrated highly accurate intracortical BCIs for speech and cursor control, but two critical capabilities needed for practical viability were unmet: independent at-home operation without researcher assistance and reliable long-term performance supporting accurate speech and cursor decoding. Here we demonstrate the independent and near-daily use of a multimodal BCI with novel brain-to-text speech and computer cursor decoders by a man with paralysis and severe dysarthria due to amyotrophic lateral sclerosis. Over nearly 2\u2009years, the participant used the BCI for more than 3,800\u2009h at home with no researchers present to maintain rich interpersonal communication with his family and friends, independently control his personal computer and sustain full-time employment-despite being paralyzed. He communicated 183,060 sentences-totaling 1,960,163 words-at an average rate of 56 words per minute. He labeled 92% of sentences as being decoded at least mostly correctly. In formal quantifications of performance where he was asked to say words presented on a screen, attempted speech was consistently decoded with more than 99% word accuracy (125,000 word vocabulary). The participant also used the speech BCI as keyboard input and the cursor BCI as mouse input to control his personal computer, enabling him to send text messages and emails and to browse the internet. These results demonstrate that intracortical BCIs have the potential to support independent use in the home, marking a critical step toward practical assistive technology for people with severe motor impairment."

Speaking rate (syllables/total duration) and articulation rate (syllables/speaking time) were measured manually and with an automated script across speakers with multiple sclerosis (MS), Parkinson's disease (PD), and healthy controls. Sixty participants (20 per group) completed sentence, paragraph, and monologue tasks (N\u2009=\u2009180 recordings).

Automated speaking rate measures showed strong correlations with manual measures across all groups and tasks (r\u2009=\u20090.623-0.998). However, default automated estimates underestimated both speaking and articulation rates, especially in clinical speakers and for the monologue task.

The absence of specific diagnostic biomarkers leads to diagnostic delays, hindering early intervention and management. This review provides a critical appraisal of fluid-based biomarkers for ALS across multiple sources-cerebrospinal fluid (CSF), blood, urine, saliva, and tears-with emphasis on their diagnostic and prognostic potential, limitations, and readiness for clinical translation. While neurofilaments (NfL, pNfH) are well-established as sensitive indicators of neuroaxonal injury and are increasingly used as prognostic and pharmacodynamic markers in clinical trials, they lack disease specificity. Biomarkers reflecting ALS-specific pathology, such as TDP-43 species and C9orf72 dipeptide repeat proteins (DPRs), show promise but remain in early validation stages with limited multicenter data. Emerging markers from non-invasive sources (urine p75ECD, salivary chromogranin A, tear metabolomics) offer potential for repeated sampling but require rigorous external validation before clinical adoption. To address current gaps, we introduce a standardized evidence grading framework (Tier 1-3) and a comprehensive reporting template for biomarker studies, including explicit performance metrics (AUC, sensitivity, specificity, confidence intervals) and validation status. We also propose minimum reporting standards for study design, pre-analytical variables, and statistical rigor, modeled on REMARK guidelines. A roadmap for biomarker validation and a cross-fluid comparison matrix are provided to guide future research. Despite considerable progress, significant challenges remain, including biological heterogeneity, pre-analytical variability, and insufficient external validation. Future efforts should prioritize multicenter prospective studies, assay harmonization, ethical frameworks for early diagnosis, and integration of emerging technologies such as artificial intelligence and digital twins. Fluid-based biomarkers, while not yet replacing clinical evaluation, are essential tools for accelerating drug development, enabling patient stratification, and moving toward personalized medicine in ALS."

Recent reductions in global health funding have threatened TB control, making comprehensive assessment of TB, HIV-related TB, and drug-resistant TB burdens before these disruptions essential for shaping effective responses. The WHO End TB Strategy sets targets of a 95% reduction in TB deaths and a 90% reduction in TB incidence between 2015 and 2035. Using results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023, this study aims to assess the burden of TB and multidrug-resistant TB (MDR-TB) across 204 countries and territories, and to evaluate progress towards the WHO End TB incidence and mortality targets. We quantified TB mortality using the Cause of Death Ensemble modelling platform with global vital registration, surveillance, verbal autopsy, and minimally invasive tissue sampling data. For TB morbidity estimation, we simultaneously modelled incidence, prevalence, and mortality by age and sex using DisMod-MR 2.1. A population attributable fraction (PAF) approach was applied to stratify morbidity and mortality estimates by HIV and drug-resistance status. We also calculated disability-adjusted life-years (DALYs) as the sum of years of life lost and years lived with disability. For the risk factor analysis, a comparative risk assessment framework was used and PAFs were derived for alcohol use, smoking, and high fasting plasma glucose to determine the proportion of TB burden associated with these risk factors. In 2023, there were an estimated 9\u00b711 million (95% uncertainty interval 8\u00b704-10\u00b73) incident cases of all-form TB, 1\u00b722 million (0\u00b798-1\u00b749) deaths, and 54\u00b76 million (43\u00b78-65\u00b75) DALYs globally. HIV-related TB comprised 781\u2008000 (690\u2008000-879\u2008000) incident cases and 210\u2008000 (142\u2008000-279\u2008000) deaths, contributing 11\u00b70 million (7\u00b756-14\u00b73) DALYs. MDR-TB accounted for 466\u2008000 (198\u2008000-1\u2008080\u2008000) incident cases, 102\u2008000 (31\u2008700-238\u2008000) deaths, and 3\u00b796 million (1\u00b731-9\u00b701) DALYs. From 2015 to 2023, global all-form TB incidence rates declined by 19\u00b72% (17\u00b78-20\u00b75) and deaths declined by 22\u00b76% (4\u00b77-35\u00b77); declines were larger for drug-susceptible TB than for MDR-TB. Sub-Saharan Africa and south Asia had the highest mortality burdens in 2023; reductions in all-form TB incidence and mortality were uneven between 2000 and 2023, with limited progress in both measures in Latin America and the Caribbean. Removing smoking, alcohol use, and high fasting plasma glucose would reduce global TB deaths to 768\u2008000 (592\u2008000-970\u2008000) and DALYs to 34\u00b79 million (27\u00b78-43\u00b78) in 2023; MDR-TB deaths would decrease to 77\u2008200 (23\u2008400-183\u2008000) and DALYs to 3\u00b712 million (1\u00b703-7\u00b729). Global progress towards WHO End TB targets is disparate and fragile. Although many regions achieved meaningful gains, others have stagnated in recent years. The complexity of TB prevention is amplified by divergent MDR-TB trends, the persistent burden of HIV, and growing exposure to modifiable risk factors. Recent volatility in global health financing threatens to further destabilise this vulnerable epidemiological landscape; concerted action is urgently needed to temper disruptions and preserve progress.

The literature demonstrates that while overt bulbar impairment is a feature of disease progression, advanced signal processing and neuroimaging provide evidence that cortical motor neuron degeneration is embedded in the brain architecture before the overt clinical manifestation of degeneration. Current digital platforms, including automated speech timing measures, allow for the identification of potential prognostic indicators in speech production that bypass the limitations of traditional, rater-dependent scales.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe early detection of ALS remains a clinical challenge due to the reliance on traditional neurological examinations, which often fail to capture subtle bulbar motor neuron degeneration. Research utilizing high-density neuroimaging and digital speech analysis suggests that cortical dysfunction is present before the transition to overt systemic degradation. Specifically, thinning of the oral motor cortex correlates with reduced oral motor function, serving as a sensitive marker for underlying neuronal instability. Longitudinal analysis of speech parameters, such as articulation rates, indicates that these measures capture bulbar decline with greater sensitivity than traditional scoring tools. Furthermore, advanced classification frameworks\u2014ranging from gene-miRNA signatures in PBMCs to machine learning-derived electrophysiological signatures\u2014are defining new diagnostic horizons. The shift toward non-invasive digital endpoints provides a scalable approach to monitor these subtle changes in the pre-symptomatic phase, offering a potential path for earlier intervention.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Thinning of the bilateral oral motor cortices is an anatomical precursor that maps directly to measurable decrements in oral motor function.\n*   Automated speaking and articulation rates provide a robust alternative to manually conducted assessments, which are prone to observer bias.\n*   Digital speech-derived measures demonstrate clear neuroanatomical correlations where standard bulbar subscores in the ALSFRS-R do not.\n*   The use of intracortical brain-computer interfaces (BCIs) has allowed for long-term monitoring, producing datasets with high word accuracy that validate the stability of speech-based tracking.\n*   Cortical dysfunction originates in a developmental trajectory in cultured cortical networks, suggesting that network collapse is a final stage of a long-standing process.\n*   The combination of digital endpoints (spirometry, accelerometry, and speech) yields high protocol adherence, supporting their future integration into standard clinical workflows.\n*   The identification of a gene-miRNA signature in PBMCs provides a molecular foundation that mirrors the central pathology of TDP-43 in ALS.\n*   Machine learning models are increasingly capable of identifying electrophysiological signatures in neuronal networks that predate overt degeneration.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

We evaluated the feasibility of a multimodal home monitoring protocol in ALS. Methods: We conducted a 3-month prospective cohort study at the University Medical Center Utrecht, Netherlands, with monthly home assessments of spirometry, accelerometry, speech, and questionnaires on functioning. The primary outcome was protocol adherence, defined as percentage of completed assessments. Secondary outcomes included acceptability ((totally) agree, neutral, (totally) disagree), and perceived burden, ranging from 0 (no burden) to 10 (extremely burdensome). Exploratory analyses were performed to evaluate changes in digital endpoints using linear mixed-effects models. Findings: Fifty patients with ALS were included (January 2023 - June 2025), of whom 47 (94%) completed the 3-month follow-up. Overall adherence was 83.2% (95% CI 76.9-88.6) and did not differ across modalities (p\u2009=\u20090.75). Adherers did not differ from non-adherers in either demographic or disease characteristics. In month 3, 93.0% to 95.3% of patients considered monthly remote assessments as acceptable, with a mean burden score of 2.0 (95% CI 1.7 to 2.3); burden was highest for speech (2.5) and the lowest for questionnaires (1.5). Digital endpoints showed significant change over 3\u2009months (all p\u2009<\u20090.05). Interpretation: This study demonstrates good adherence and acceptability of a multimodal remote monitoring protocol. Digital endpoints offer an innovative approach to capturing disease progression. Future research should assess its long-term feasibility, added value, and integration alongside established clinical outcomes.\n\nID: 42385762\nTitle: Global, regional, and national burden of tuberculosis and multidrug-resistant tuberculosis by HIV status, 1990-2023: a systematic analysis for the Global Burden of Disease Study 2023.\nAbstract: Tuberculosis (TB) is the leading global cause of death from a single infectious agent. Recent reductions in global health funding have threatened TB control, making comprehensive assessment of TB, HIV-related TB, and drug-resistant TB burdens before these disruptions essential for shaping effective responses. The WHO End TB Strategy sets targets of a 95% reduction in TB deaths and a 90% reduction in TB incidence between 2015 and 2035. Using results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023, this study aims to assess the burden of TB and multidrug-resistant TB (MDR-TB) across 204 countries and territories, and to evaluate progress towards the WHO End TB incidence and mortality targets. We quantified TB mortality using the Cause of Death Ensemble modelling platform with global vital registration, surveillance, verbal autopsy, and minimally invasive tissue sampling data. For TB morbidity estimation, we simultaneously modelled incidence, prevalence, and mortality by age and sex using DisMod-MR 2.1. A population attributable fraction (PAF) approach was applied to stratify morbidity and mortality estimates by HIV and drug-resistance status. We also calculated disability-adjusted life-years (DALYs) as the sum of years of life lost and years lived with disability. For the risk factor analysis, a comparative risk assessment framework was used and PAFs were derived for alcohol use, smoking, and high fasting plasma glucose to determine the proportion of TB burden associated with these risk factors. In 2023, there were an estimated 9\u00b711 million (95% uncertainty interval 8\u00b704-10\u00b73) incident cases of all-form TB, 1\u00b722 million (0\u00b798-1\u00b749) deaths, and 54\u00b76 million (43\u00b78-65\u00b75) DALYs globally. HIV-related TB comprised 781\u2008000 (690\u2008000-879\u2008000) incident cases and 210\u2008000 (142\u2008000-279\u2008000) deaths, contributing 11\u00b70 million (7\u00b756-14\u00b73) DALYs. MDR-TB accounted for 466\u2008000 (198\u2008000-1\u2008080\u2008000) incident cases, 102\u2008000 (31\u2008700-238\u2008000) deaths, and 3\u00b796 million (1\u00b731-9\u00b701) DALYs. From 2015 to 2023, global all-form TB incidence rates declined by 19\u00b72% (17\u00b78-20\u00b75) and deaths declined by 22\u00b76% (4\u00b77-35\u00b77); declines were larger for drug-susceptible TB than for MDR-TB. Sub-Saharan Africa and south Asia had the highest mortality burdens in 2023; reductions in all-form TB incidence and mortality were uneven between 2000 and 2023, with limited progress in both measures in Latin America and the Caribbean. Removing smoking, alcohol use, and high fasting plasma glucose would reduce global TB deaths to 768\u2008000 (592\u2008000-970\u2008000) and DALYs to 34\u00b79 million (27\u00b78-43\u00b78) in 2023; MDR-TB deaths would decrease to 77\u2008200 (23\u2008400-183\u2008000) and DALYs to 3\u00b712 million (1\u00b703-7\u00b729). Global progress towards WHO End TB targets is disparate and fragile. Although many regions achieved meaningful gains, others have stagnated in recent years. The complexity of TB prevention is amplified by divergent MDR-TB trends, the persistent burden of HIV, and growing exposure to modifiable risk factors. Recent volatility in global health financing threatens to further destabilise this vulnerable epidemiological landscape; concerted action is urgently needed to temper disruptions and preserve progress.

How can the introduction of an organized, risk-adapted prostate cancer screening program in Germany shape preventive urology of the future? This narrative review article is based on guidelines and expert consensus supported by a\u00a0literature search in PubMed. The cited studies represent the most relevant work on this topic and were selected to illustrate developments and fundamental concepts; however, completeness is not claimed. Serum prostate-specific antigen (PSA) levels and prostate MRI not only identify patients at increased risk for prostate cancer but also offer insights into other urological conditions, such as lower urinary tract symptoms and hypogonadism. In analogy to other early detection strategies, PSA testing at the age of 45-50\u00a0years could serve as a\u00a0simple triage test to guide risk-adapted follow-up and timely referral to urological care. Lifestyle factors-including regular physical activity, a\u00a0balanced diet, and pelvic floor training-may favorably influence urological health and related outcomes. While organized prostate cancer screening has already been shown to improve cancer-specific mortality to a\u00a0level comparable to mammography, a\u00a0more holistic approach may further enhance its overall benefit. Urology has significant opportunities to actively promote healthy behaviors among aging men. The establishment of an organized prostate cancer screening program provides an ideal entry point for this purpose. Modern screening concepts should incorporate holistic health promotion for aging men alongside direct oncological endpoints. HINTERGRUND: Die Etablierung einer organisierten, risikoadaptierten Prostatakarzinomfr\u00fcherkennung k\u00f6nnte Grundlage einer pr\u00e4ventiven M\u00e4nnergesundheit sein. Wie kann die Einf\u00fchrung einer organisierten, risikoadaptierten Prostatakarzinomfr\u00fcherkennung die pr\u00e4ventive Urologie von morgen pr\u00e4gen? Dieser narrative \u00dcbersichtsartikel auf der Grundlage von Leitlinien und Expertenkonsens wird unterst\u00fctzt durch eine Literaturrecherche auf PubMed (2000\u20132026). Die zitierten Studien stellen nach Meinung der Autoren die relevanten Arbeiten hierzu dar und wurden ausgew\u00e4hlt, um Entwicklungen und prinzipielle Konzepte zu veranschaulichen, beanspruchen jedoch keine Vollst\u00e4ndigkeit. Der PSA-Wert (prostataspezifisches Antigen) und die MRT liefern nicht nur Hinweise auf ein Prostatakarzinom, sondern auch auf andere urologische Erkrankungen wie Miktionsbeschwerden oder Testosteronmangel. Parallel zu anderen Fr\u00fcherkennungsuntersuchungen k\u00f6nnte der PSA-Wert mit 45\u201350\u00a0Jahren als einfaches Triage-Tool fungieren, um risikoadaptierte Verlaufskontrollen sowie fachurologische Vorstellungen zu steuern. Lebensstilfaktoren wie Bewegung, eine gesunde Ern\u00e4hrung und Beckenbodentraining k\u00f6nnen urologische Erkrankungen und deren Folgen positiv beeinflussen. Durch eine organisierte Prostatakarzinomfr\u00fcherkennung kann das karzinomspezifische Mortalit\u00e4t bereits heute vergleichbar zur Mammographie verbessert werden, durch ein holistischeres Herangehen kann der Gesamtnutzen jedoch noch mehr gesteigert werden. Die Urologie hat gro\u00dfe Chancen, die Gesundheitskompetenz des alternden Mannes, aber auch Fr\u00fcherkennungsma\u00dfnahmen f\u00fcr andere Erkrankungen, aktiv zu f\u00f6rdern. Die organisierte Prostatakarzinomfr\u00fcherkennung k\u00f6nnte hierf\u00fcr einen sinnvollen Einstieg darstellen. Moderne Fr\u00fcherkennungskonzepte sollten die ganzheitliche Gesundheitsf\u00f6rderung des alternden Mannes neben direkten onkologischen Endpunkten miteinbeziehen.\n\nID: 42356052\nTitle: Association Between Clinical Dysphagia Assessment Tools and Videofluoroscopic Findings in Amyotrophic Lateral Sclerosis: A Retrospective Study.\nAbstract: Background and Objectives: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease frequently associated with dysphagia and aspiration risk. This study aimed to investigate the relationship between clinical dysphagia assessment tools (EAT-10, GUSS, RSST, and sialorrhea severity) and videofluoroscopic swallowing study (VFSS) findings in patients with ALS. Materials and Methods: This retrospective observational study included 60 patients with ALS classified as spinal-onset (n = 38) or bulbar-onset (n = 22). Relationships between clinical assessments and VFSS findings were analysed using Spearman correlation analysis. Exploratory multivariable regression and receiver operating characteristic (ROC) analyses were performed to evaluate associations and aspiration risk discrimination. Results: Strong negative correlations were observed between PAS-Liquid and RSST and GUSS scores, whereas EAT-10 showed a strong positive correlation (all p < 0.001). ROC analyses demonstrated good discriminative ability for aspiration risk for GUSS (AUC = 0.89), RSST (AUC = 0.88), and EAT-10 (AUC = 0.82). Patients with bulbar-onset ALS demonstrated higher penetration-aspiration severity and lower functional oral intake. Conclusions: Clinical dysphagia assessment tools showed significant associations with instrumental swallowing findings in ALS. GUSS and RSST demonstrated good discriminative ability for aspiration risk and may be clinically useful bedside screening tools. However, instrumental swallowing assessment remains essential whenever feasible.\n\nID: 42333954\nTitle: Thinning of the oral motor cortex is linked to impaired speech in amyotrophic lateral sclerosis.\nAbstract: Most individuals with amyotrophic lateral sclerosis (ALS) develop bulbar impairment as their disease progresses. The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech\u2011derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1\u2011weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS.\n\nID: 42329964\nTitle: Applications of electromyography in Amyotrophic Lateral Sclerosis: A systematic review.\nAbstract: This systematic review examined the use of surface electromyography (sEMG) for the neuromuscular assessment of individuals with Amyotrophic Lateral Sclerosis (ALS), focusing on clinical parameters, the muscle groups evaluated, acquisition protocols, technical properties of the recording systems, integration with other technologies, and signal processing strategies. We included observational studies that applied sEMG to individuals diagnosed with ALS, with or without comparison to healthy controls, and without restrictions on publication year. The analyses included signals recorded at rest and during voluntary contractions, with or without the use of biofeedback. Most studies employed conventional or high-density surface electrodes, with sampling frequencies ranging from 500 Hz to 3000 Hz. The results showed that the primary parameters assessed were muscle fatigue, fasciculation patterns, the number of motor units (MUNE/MUNIX), motor unit firing rates, and signal complexity. These parameters demonstrated sensitivity to disease progression and may contribute to early diagnosis, phenotypic stratification, and functional monitoring of ALS. Additionally, the studies highlighted the increasing use of advanced computational approaches, such as machine learning, for feature extraction and automated classification. In conclusion, sEMG is a promising tool for functional assessment in ALS, with the potential to improve diagnostic accuracy and support new therapeutic strategies based on electrophysiological biomarkers. However, despite technological advances, the included studies displayed substantial methodological heterogeneity and limited protocol standardization. Integration with other neurophysiological modalities also remains underexplored, despite its significant clinical potential.\n\nID: 42318821\nTitle: 3D-printed lab-on-chip platforms for the detection of neurodegenerative diseases: opportunities and challenges.\nAbstract: Neurodegenerative diseases (NDs) such as Alzheimer's, Parkinson's, and ALS remain some of the most challenging disorders to diagnose at an early stage. Conventional approaches rely on costly neuroimaging or invasive cerebrospinal fluid sampling, which limit accessibility and early intervention. Recent advances in 3D printing have enabled rapid prototyping of lab-on-chip (LOC) platforms that integrate microfluidics, biosensors, and biological models to detect disease-specific biomarkers with high sensitivity and throughput. Herein, we explore the synergistic role of 3D printing technologies and biomaterials in fabricating LOC systems for NDs. We highlight key biomarkers, and neuron- and organoid-on-chip platforms, and discuss the challenges and opportunities in clinical translation. By combining technical innovation in additive manufacturing with biological relevance, 3D-printed LOC devices represent a transformative approach toward precision diagnostics in neuro-medicine.\n\nID: 42316902\nTitle: The ALS Home Health and Durable Medical Equipment Medical Standard Expert Consensus Guideline.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease associated with escalating disability and complex care needs. Although most individuals with ALS reside at home, existing US guidelines primarily address clinic-based care and provide limited direction on medically necessary home health services and durable medical equipment (DME). The objective of this task force was to develop expert consensus guidance defining minimum medical standards for home health services and DME for individuals with ALS, with the goal of improving patient outcomes, safety, and quality of life. This guideline was developed by a multidisciplinary task force convened by the American Association of Neuromuscular and Electrodiagnostic Medicine (AANEM). The process incorporated a scoping literature review, stakeholder engagement (patients, caregivers, and advocacy groups), and iterative expert consensus. Recommendations were informed by clinical expertise, patient-centered priorities, and existing policy frameworks. This guideline outlines stage-responsive home healthcare recommendations spanning nursing, home health aides, physical and occupational therapy, speech-language pathology, respiratory therapy, nutritional support, and social work. It emphasizes proactive, anticipatory care aligned with the predictable trajectory of ALS, rather than being reactive based on functional decline. The document defines medically necessary DME across domains, including mobility, communication, respiratory support, and activities of daily living, advocating for timely access independent of restrictive payer criteria. Key principles include coordinated interdisciplinary care, continuous reassessment, caregiver support, and integration of palliative care. These recommendations establish a foundational standard for ALS home-based care in the United States. Adoption may reduce delays, prevent complications, and support sustained independence and dignity for individuals with ALS.\n\nID: 42304926\nTitle: Linking Neurodegeneration and Age-related Macular Degeneration: Unified Pathways and Intervention Strategies.\nAbstract: Age-related macular degeneration (AMD) is caused by the degeneration of photoreceptors and retinal pigment epithelium (RPE) along with drusen deposition and is the leading cause of vision loss in older adults. Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration. Comparing these age-related diseases will facilitate the identification of shared risk factors, convergent molecular pathways, and potential cross-applicable therapeutic strategies, such as anti-inflammatory, anti-complementary, anti-apoptotic, and anti-VEGF-based approaches. This knowledge may enhance understanding of neurodegenerative diseases, help identify early biomarker development for diagnosis, and enable the design of targeted therapeutic strategies.\n\nID: 42296263\nTitle: Whole-body muscle MRI improves diagnostic certainty in amyotrophic lateral sclerosis.\nAbstract: Introduction: Early diagnosis of amyotrophic lateral sclerosis (ALS) remains challenging due to the absence of a definitive biomarker and the difficulty of demonstrating widespread lower motor neuron (LMN) involvement. Whole-body muscle MRI (WB-MRI) enables comprehensive assessment of muscle involvement and may improve detection of LMN dysfunction. This study aimed to evaluate whether WB-MRI improves diagnostic certainty in ALS when combined with clinical and electromyography (EMG) assessment. Methods: In this prospective single-center study, 47 patients with ALS underwent clinical examination, EMG, and WB-MRI. Diagnostic classification according to the Awaji criteria was assessed using clinical and EMG data alone and after integration of MRI markers of LMN involvement, including fatty infiltration and muscle edema, or muscle edema alone as a surrogate marker. Results: WB-MRI identified additional LMN-involved regions in 27.7% of patients when both fatty infiltration and muscle edema were considered, and in 42.6% when considering muscle edema alone. This resulted in diagnostic upgrading in 14.9% and 25.5% of patients, respectively. The proportion of definite ALS increased from 8.5% to 17.0% when muscle edema alone was considered. MRI had limited impact on diagnostic classification according to the Gold Coast criteria. Among patients without LMN involvement on clinical and EMG assessment (all with bulbar-onset), 50% were reclassified after MRI. Conclusion: WB-MRI improves detection of LMN involvement and increases diagnostic certainty according to the Awaji criteria, with muscle edema appearing to be the most relevant MRI marker for integration into ALS diagnostic assessment.\n\nID: 42290559\nTitle: Integrated Analysis of hsa-miR-26b-5p and hsa-miR-186-5p in Blood Serum and Tumor Tissue Reveals their Prognostic and Predictive Significance in Breast Cancer.\nAbstract: Breast cancer (BC) heterogeneity signifi antly complicates diagnosis, prognosis, and prediction of treatment response. MicroRNAs (miRNAs) have emerged as promising biomarkers due to their involvement in tu- mor progression and in regulating therapy sensitivity. however, the combined clinical signifi ance of circulating and tumor-associated miRNAs, such as hsa-miR-26b-5p and hsa-miR-186-5p, remains insuffi\u00a0\u00a0 \u00a0tly elucidated. Materi- als and Methods. Expression levels of hsa-miR-26b-5p and hsa-miR-186-5p were analyzed in serum and tumor tis- sue of 124 BC patients. Associations with clinicopathological parameters were assessed. The prognostic signifi ance was evaluated based on disease progression and recurrence within 3 years. The predictive value was determined in patients receiving neoadjuvant chemotherapy (4AC regimen) using response assessment and ROC analysis. Re- sults. young BC patients (\u226445 years) demonstrated signifi antly lower circulating levels of both miRNAs. Serum hsa-miR-186-5p expression was associated with early-stage disease, tumor size, lymph node status, and molecular subtype. Increased circulating hsa-miR-26b-5p levels were linked to disease progression, whereas decreased hsa- miR-186-5p levels were observed in patients with unfavorable outcomes. In tumor tissue, hsa-miR-26b-5p expres- sion correlated with tumor grade, size, and metastatic status, showing elevated levels in poorly differentiated tumors and reduced expression in metastatic disease. In contrast, hsa-miR-186-5p was associated with the molecular sub- type and lymph node involvement, with the highest expression observed in hER2-positive tumors and in patients with recurrence. Elevated levels of hsa-miR-186-5p in both serum and tumor tissue were associated with reduced sensitivity to doxorubicin-based neoadjuvant chemotherapy. ROC analysis confi med its predictive value (AUC = \u00a00.750 for serum and 0.818 for tumor tissue). No signifi ant association between hsa-miR-26b-5p and chemothe- rapy response was observed. hsa-miR-26b-5p and hsa-miR-186-5p demonstrate complementary roles in BC biology. hsa-miR-26b-5p is primarily associated with tumor aggressiveness and cancer progression, whereas hsa-miR-186-5p refl cts its molecular characteristics and response to chemotherapy. Their combined assessment in serum and tumor tissue represents a promising approach for improving prognostic stratifi ation and predicting treatment effi acy in BC patients.\n\nID: 42273832\nTitle: Remote, self-administered, smartphone cognitive testing in a registry-based cohort: Feasibility, reliability, and validity findings.\nAbstract: Remote, smartphone-based cognitive testing may improve access to cognitive assessments for Alzheimer's disease and related dementias. We evaluated the feasibility, reliability, and validity of unsupervised smartphone-based cognitive tests in a registry-based cohort. Adults without a record of cognitive impairment (N\u00a0=\u00a01815; ages 18-92) were recruited from the University of California, San Francisco (UCSF) Brain Health Registry to complete three unsupervised smartphone cognitive testing sessions within 2 weeks. Reliability was assessed with correlations between sessions. Linear regression models tested associations of smartphone tasks with demographics, self- and informant-rated cognitive concerns, and web-based cognitive testing (Cogstate Brief Battery). Adherence was high (82.2%) and usability favorable. Test-retest reliability was moderate to strong (\u03c1's\u00a0=\u00a00.61-0.85, all p's\u00a0<\u00a00.001). Lower smartphone scores were associated with older age, lower education, cognitive concerns, and worse Cogstate performance. Findings support the feasibility, reliability, and validity of remote digital assessments in adults without a record of cognitive impairment.\n\nID: 42267908\nTitle: Developmental circuit instability in amyotrophic lateral sclerosis: from hyperexcitability to network collapse.\nAbstract: Amyotrophic lateral sclerosis (ALS) is traditionally viewed as a late-onset motor neuron disease, yet how cortical dysfunction originates and contributes to pathogenesis remains unresolved. In this study, we reconstruct the developmental trajectory of cultured cortical networks derived from SOD1G93A mouse embryos using a multimodal approach, by combining morphometric, electrophysiological, pharmacological, molecular, computational, and machine-learning techniques. We prove that ALS neurons fail to acquire mature polarization and connectivity, displaying a transient phase of hyperexcitability that precedes a progressive collapse of network organization. Astrocytic dysfunction emerges early and impairs synchronization, establishing a causal link between glial dysfunction and neuronal instability. The analysis of synaptic transmission reveals an excitatory bias followed by maladaptive inhibitory recruitment and GABA/glutamate co-release, causing fragmented and inefficient network topologies. Finally, in silico modelling identified deficient intrinsic adaptation as a key driver of hyperexcitability. Together, our findings position ALS as a developmentally rooted disorder of cultured cortical network homeostasis, driven by glial, synaptic, and intrinsic adaptation failures. By demonstrating that cortical dysfunction is embedded before degeneration, this work provides a unifying framework connecting early network instability to disease progression and establishes electrophysiological network signatures, detected by machine learning classifiers, as candidate biomarkers for early diagnosis and therapeutic screening.\n\nID: 42251967\nTitle: PBMC DEG/miRNA biomarkers of TDP-43 pathology in ALS.\nAbstract: Amyotrophic lateral sclerosis (ALS) lacks reliable, disease-specific, and minimally invasive biomarkers, representing a major barrier to early diagnosis and patient stratification. The primary aim of this translational pilot study was to identify a disease-specific, TDP-43-related, gene-microRNA (miRNA) signature in peripheral blood mononuclear cells (PBMCs) of ALS patients with potential diagnostic value. To this end, we first identified differentially expressed disease-specific genes (dsDEGs) using a TDP-43-based rat model of ALS, generated by stereotaxic infusion of full-length (FL) TAR DNA-binding protein 43 (TDP-43) into the motor cortex. Transcriptomic profiling of the motor cortex revealed candidate dsDEGs, which were subsequently validated by RT-qPCR in motor cortex, spinal cord, and PBMCs from the same animals. To assess translational relevance, expression levels of these dsDEGs were analyzed in PBMCs from early- to mid-stage ALS patients and matched healthy controls, while disease specificity was evaluated using Parkinson's disease (PD) samples. In parallel, conserved miRNAs predicted to target the identified dsDEGs were examined in both rat and human PBMCs. Five dsDEGs, Mctp1, Penk, Mt2A, Drd1, and Rasgrp2, were consistently dysregulated across central and peripheral tissues in the TDP-43 rat model. RT-qPCR analysis of human PBMCs confirmed significant and selective dysregulation of these genes in ALS, but not in PD, supporting disease specificity. Moreover, exposure of human neuroblastoma cells and healthy PBMCs to TDP-43 recapitulated the ALS-like expression changes. Computational and experimental analyses identified seven conserved miRNAs targeting these dsDEGs, of which four were significantly downregulated in ALS PBMCs, supporting a coordinated regulatory network. Receiver operating characteristic (ROC) analyses demonstrated strong discriminative performance for both the gene signature (AUC 0.87-1.00) and the associated miRNAs (AUC 0.95-1.00). Together, these findings define a novel PBMC-based gene-miRNA signature that mirrors central ALS pathology and shows high diagnostic accuracy and disease specificity, highlighting its potential as a minimally invasive biomarker for ALS.\n\nID: 42241188\nTitle: The Unfinished Breath: Caregiver Perceptions of Terminal Events and Gaps in Amyotrophic Lateral Sclerosis Care in India.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder with a high symptom burden and limited survival. Little is known about the terminal phase experiences, symptom prevalence, and end-of-life care patterns of people with ALS (PALS) in India. This study aimed to assess terminal events and caregiver-reported outcomes in PALS to identify gaps in ALS care delivery in India. A cross-sectional telephonic survey was conducted among bereaved caregivers of PALS enrolled in the Neuropalliative and Supportive Care project between December 2021 and May 2024. A structured, validated questionnaire was used to collect data on demographics, terminal-phase symptoms, medical interventions, and the nature of death as perceived by primary caregivers. Descriptive statistics and appropriate statistical analyses were performed. A total of 130 caregivers participated in the survey; the majority (57.7%) were sons or daughters. Among the 130 PALS, 76 (58.5%) were men; 56.2% had limb onset and 43.8% had bulbar onset. The mean age at death was 53.5 \u00b1 11.4 years. Most patients (57.7%) died at home, and 29.2% experienced sudden death. Patients who died in the hospital were more likely to be on invasive mechanical ventilation ( P < 0.001). The most common terminal symptoms were breathlessness (79.2%), excessive oral secretions (54.6%), followed by anxiety or restlessness (44.6%). Only 20% received bilevel positive airway pressure, and 25.4% were on percutaneous endoscopic gastrostomy. A significant association was found between bulbar onset and assisted feeding ( P = 0.002). This study highlights the need for proactive, community-integrated palliative care services and emphasizes the urgency of early intervention and caregiver support to improve end-of-life experiences in PALS in India.\n\nID: 42225765\nTitle: Longitudinal cognitive assessment using the Cumulus NeuLogiq platform in amyotrophic lateral sclerosis and frontotemporal dementia.\nAbstract: People living with ALS (plwALS) and/or FTD (plwFTD) often experience cognitive and behavioural changes. However, detection can be confounded due to factors like fatigue and testing anxiety. Cumulus neuroscience developed NeuLogiq(R), a multi-modal neurocognitive platform that can be used in clinic or at home, providing an ecologically valid measure of cognition. This study examined the feasibility and usability of NeuLogiq in plwALS, plwFTD, and controls, and compared performance on gold standard neuropsychological assessments with corresponding NeuLogiq digital assessments. Over 8 months, plwALS (n\u2009=\u200911), plwFTD (n\u2009=\u20097), and matched healthy controls (n\u2009=\u200910) completed longitudinal full neuropsychological assessment, as well as three 25-minute NeuLogiq Platform sessions every 2 weeks in their homes. Participants adhered well to the study schedule, conducting over 32/54 sessions on average. All groups rated usability in the 'good' or 'excellent' range and had\u2009>\u200980% complete data. Baseline group differences were detectable on both NeuLogiq digital assessments and benchmark neuropsychological assessments of similar cognitive domains. Longitudinal mixed effects models found that the ALS group showed decline on NeuLogiq measures of emotion recognition and speech fluency. These findings suggest that the NeuLogiq platform is feasible and usable for plwALS and plwFTD, and can identify cognitive deficits to a similar extent as benchmark assessments over time.\n\nID: 42217760\nTitle: Fluid-based biomarkers of amyotrophic lateral sclerosis: recent advances and future prospects.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disorder with no definitive cure. The absence of specific diagnostic biomarkers leads to diagnostic delays, hindering early intervention and management. This review provides a critical appraisal of fluid-based biomarkers for ALS across multiple sources-cerebrospinal fluid (CSF), blood, urine, saliva, and tears-with emphasis on their diagnostic and prognostic potential, limitations, and readiness for clinical translation. While neurofilaments (NfL, pNfH) are well-established as sensitive indicators of neuroaxonal injury and are increasingly used as prognostic and pharmacodynamic markers in clinical trials, they lack disease specificity. Biomarkers reflecting ALS-specific pathology, such as TDP-43 species and C9orf72 dipeptide repeat proteins (DPRs), show promise but remain in early validation stages with limited multicenter data. Emerging markers from non-invasive sources (urine p75ECD, salivary chromogranin A, tear metabolomics) offer potential for repeated sampling but require rigorous external validation before clinical adoption. To address current gaps, we introduce a standardized evidence grading framework (Tier 1-3) and a comprehensive reporting template for biomarker studies, including explicit performance metrics (AUC, sensitivity, specificity, confidence intervals) and validation status. We also propose minimum reporting standards for study design, pre-analytical variables, and statistical rigor, modeled on REMARK guidelines. A roadmap for biomarker validation and a cross-fluid comparison matrix are provided to guide future research. Despite considerable progress, significant challenges remain, including biological heterogeneity, pre-analytical variability, and insufficient external validation. Future efforts should prioritize multicenter prospective studies, assay harmonization, ethical frameworks for early diagnosis, and integration of emerging technologies such as artificial intelligence and digital twins. Fluid-based biomarkers, while not yet replacing clinical evaluation, are essential tools for accelerating drug development, enabling patient stratification, and moving toward personalized medicine in ALS.\n\nID: 42214970\nTitle: The beat in speech: A window into the attentional mechanisms supporting the detection of non-adjacent dependencies.\nAbstract: Converging evidence suggests that musical training can elicit positive transfer effects across multiple domains of language processing, including grammar. In humans, exposure to musical rhythm induces beat and meter perception, which has been shown to enhance attentional allocation and temporal prediction. Theories hypothesize that the predictive gains intrinsic to music rhythmicity may exert cascading effects on syntactic processing by modulating sensitivity to speech prosody. From this perspective, learning should also be boosted insofar as prosody tends to align with grammatical structure. In the present study, we introduce a novel behavioural paradigm to investigate the link between rhythmicity and grammar learning by testing whether the rhythmic beat facilitates the detection of grammar-like structures in artificial languages (ALs), implemented as non-adjacent dependencies (NADs) between variable syllables forming a speech stream (e.g., PU reliably predicts KI in PUlaruKI). A total of 147 participants were exposed to four ALs that varied in rhythmic, grammatical structure, and the alignment between the two: (i) a beat-inducing rhythm with no NADs; (ii) a beat-hindering rhythm with NADs; (iii) a beat-inducing rhythm with embedded NADs temporally misaligned, and (iv) NADs aligned with beat time-points. Results of the implicit and, after exposure, explicit learning measures demonstrate enhanced learning when NADs are embedded within beat-inducing rhythmic structures. Together, these findings suggest that rhythm enhances predictive and attentional mechanisms implicated in grammar learning, underscoring their role in its acquisition.\n\nID: 42212970\nTitle: DIGEST Grades Remain Stable With Inclusion of Moderately Thickened Liquids in the Videofluoroscopic Examination in Individuals With Amyotrophic Lateral Sclerosis.\nAbstract: The Dynamic Imaging Grade of Swallowing Toxicity (Version 2; DIGESTV2) is a videofluoroscopy (VF) scale that measures pharyngeal swallowing severity based on functional measures of swallowing safety and efficiency. Original validation is based on a standard VF testing protocol including thin liquid, puree, and solid consistencies. Given that thickened liquid bolus trials are common in VF clinical testing protocols, we sought to determine the agreement in DIGESTV2 grades with and without the inclusion of moderately thick liquid bolus trials on DIGESTV2 outcomes in people with amyotrophic lateral sclerosis (pALS). This study represents a secondary analysis of VF examinations from a prospective longitudinal study conducted in 109 pALS. VF evaluations contained 10 barium trials spanning three International Dysphagia Diet Standardisation Initiative (IDDSI) levels (0-7). Duplicate, independent, and blinded ratings were completed. DIGESTV2 Efficiency and Safety grading was then completed under two conditions-with and without the inclusion of moderately thick liquid bolus trials into DIGESTV2 grading-to produce two sets of DIGESTV2 ratings for each VF study. Descriptives, percent agreement, and a weighted Cohen's kappa were performed on DIGESTV2 grades. A total of 373 VF examinations were included in this analysis. DIGESTV2 grade percent agreement with and without IDDSI Level 3 was excellent for Safety (98.1%), Efficiency (93.8%), and Total (94.1%) grades. Kappa values for Safety, Efficiency, and Total grades were .96, .89, and .91, respectively, indicating excellent agreement across bolus trial inclusion methods. Standard inclusion of moderately thick liquid bolus trials did not significantly impact DIGESTV2 grading in this data set. These results add to the preliminary but growing evidence suggesting stability of DIGEST grading with alternate bolus protocols in another patient population. https://doi.org/10.23641/asha.32348451.\n\nID: 42211895\nTitle: Peripheral immune cells and glycation indices as potential diagnostic biomarkers in amyotrophic lateral sclerosis.\nAbstract: The diagnosis of amyotrophic lateral sclerosis (ALS) mainly relies on clinical symptoms and the exclusion of other diseases, with a lack of specific biomarkers, leading to delayed diagnosis and a high rate of misdiagnosis. This study aims to explore the utility of peripheral immune cells and glycosylation indices as potential diagnostic biomarkers for ALS to enhance the accuracy and efficiency of early ALS diagnosis. This retrospective study included 54 ALS patients diagnosed in our hospital from June 2023 to October 2024, along with 54 healthy controls. Blood samples and laboratory data, including levels of peripheral immune cells and glycosylation indices, were collected from both groups. Through logistic regression, random forest models, receiver operating characteristic (ROC) curve analysis, and SHAP interpretability analysis, the predictive abilities and clinical significance of each candidate indicator were screened and evaluated. Notable disparities were detected in age, leukocyte count, monocyte levels, glycated haemoglobin A1c (HbA1c), and haemoglobin glycation index (HGI) between the control and ALS groups (all P < 0.05). Logistic regression analysis revealed that age (OR = 1.114) and monocyte (OR = 3.174) were risk factors for ALS, while leukocyte (OR = 0.533) and HbA1c (OR = 0.069) were protective factors. The random forest algorithm, ranked by decreasing importance, showed that leukocyte, HGI, monocyte, and HbA1c level all influenced ALS. Using these indicators to predict ALS resulted in a false-positive rate of 18% and a false-negative rate of 6%. ROC curve analysis indicated that the combined use of leukocyte, monocyte, HbA1c level, and HGI provided the highest diagnostic value for ALS (AUC = 0.774), which was higher than that of any individual indicator (all P < 0.05). SHAP analysis visualization demonstrated that increased monocyte and decreased leukocyte, HGI, and HbA1c level were all associated with an increased risk of ALS onset, ranked in descending order of feature importance as monocyte, leukocyte, HGI, and HbA1c. Peripheral blood white blood cells, monocytes, HbA1c, and HGI can serve as potential diagnostic biomarkers for ALS. Combined detection can improve the diagnostic accuracy of ALS, facilitating early diagnosis and intervention, and ultimately improving patient prognosis. Further validation in cohorts including disease controls is required to confirm specificity.\n\nID: 42193936\nTitle: Emerging Therapeutic Strategies for Neurodegenerative Diseases: A Comprehensive Review of Recent Advances and Future Directions.\nAbstract: Neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS; Lou Gehrig's disease), represent a growing global health burden characterized by progressive neuronal loss and functional decline. Despite decades of intensive research, effective disease-modifying therapies remain limited, underscoring the urgent need for innovative therapeutic strategies. This review highlights recent advances in the understanding of disease etiology and emerging treatment approaches, with a particular focus on modalities with translational potential. We discussed novel disease-modifying interventions, including gene and cell therapies, RNA-targeting strategies, and immunotherapies aimed at clearing misfolded proteins such as amyloid-\u03b2, tau, and \u03b1-synuclein. In parallel, we examined the evolving recognition of neuroinflammation and mitochondrial dysfunction as actionable therapeutic targets, alongside progress in precision medicine and biomarker-guided approaches that enable early diagnosis and individualized treatment. Additionally, we summarized developments in repurposed pharmacological agents, neuroprotective compounds, and lifestyle interventions, emphasizing the importance of integrative, multimodal strategies. Across AD, PD, and ALS, convergent molecular mechanisms, including protein misfolding, oxidative stress, and disrupted proteostasis, present opportunities for cross-disease therapeutic targeting. Finally, we addressed key challenges and future directions, including translating preclinical efficacy into clinical success, optimizing CNS-targeted delivery systems, and navigating ethical considerations surrounding gene editing and stem cell therapies.\n\nID: 42410716\nTitle: Greater choroid plexus volume is linked to poor sleep, neurodegeneration, and cognitive deficits in older adults: Evidence from the IGNITE Study.\nAbstract: Poor sleep is associated with neurodegenerative disease, but mechanisms are unclear. Greater volume of the choroid plexus (ChP), a brain structure supporting neurotoxic waste clearance, is linked to neurodegeneration and cognitive decline. We tested whether poor sleep promotes neurodegeneration and cognitive deficits via ChP dysfunction. Baseline magnetic resonance imaging (MRI) -derived ChP, hippocampal, ventricular, and gray matter volumes from 635 cognitively unimpaired older adults were analyzed. Sleep was measured with the Pittsburgh Sleep Quality Index and accelerometry. Confirmatory factor analysis generated cognitive domain scores. Poorer self-reported sleep quality was associated with greater ChP volume, while accelerometry measures were not. Greater ChP volume was associated with smaller hippocampi and gray matter, and larger ventricles. ChP mediated relationships between sleep quality and hippocampal and ventricular volumes. Gray matter mediated associations between ChP and cognitive domains. Altered ChP morphology may link poor sleep to neurodegeneration and cognitive decline in older adults.\n\nID: 42410680\nTitle: Neuropathology-specific language features in primary progressive aphasia.\nAbstract: Primary Progressive Aphasia (PPA) clinical syndromes do not align consistently with underlying pathology. This study aimed to identify language markers for specific neuropathologies using both standard clinical tests and narrative speech analysis. We analyzed data from 82 autopsy-confirmed PPA cases, including Alzheimer's disease (AD), transactive DNA-binding protein 43 (TDP-43) type C (TDP-C), Pick's disease, and 4R-tauopathies (progressive supranuclear palsy/ cortico-basal degeneration (PSP/CBD). Linear mixed-effects regression was used to analyze performance on standardized aphasia tests and narrative speech variables. TDP-C showed severe semantic deficits but high fluency, while AD was distinguished by impaired repetition. Narrative analysis differentiated 4R-Tauopathies: CBD patients demonstrated significantly poorer syntax and irregular verb inflection than PSP or Pick's, whereas PSP showed the lowest fluency. While standard tests effectively capture lexical-semantic features in AD and TDP-C, narrative measures reveal subtle grammatical and fluency differences critical for distinguishing specific tauopathies. This study outlines a more robust approach for predicting underlying pathology in PPA.\n\nID: 42384624\nTitle: Development and validation of a machine learning model to detect psychiatric symptoms in Huntington's disease using speech analysis.\nAbstract: Huntington's disease (HD) causes progressive disability through motor, psychiatric, and cognitive symptoms. Machine learning speech analysis can detect motor and cognitive symptoms of HD, but not yet psychiatric symptoms. This study investigated whether speech analyses can detect the presence of psychiatric symptoms in HD. Audio recordings of six narrative tasks (cookie-theft picture description, red-riding hood storytelling, most recent 24 hours recalling, happy, sad, or angry storytelling) were prospectively collected from subsequent genetically confirmed HD participants from the BIOHD and REPAIR CAPIT-HD-Beta cohorts at the Hospital Henri-Mondor, Cr\u00e9teil. Speech therapists blindly annotated speech samples to allow extraction of three types of features: linguistic, LASER, and acoustic features. Psychiatric symptoms in participants were detected using the Problem Behaviors Assessment Short version (PBA-s). Machine learning classifier models were trained on 80% of the 89 participants before being tested on the remaining 20% of individuals. F1-scores were calculated and compared to chance. Linguistic features detected obsessive/compulsive behavior (OCB) with all but joy task, and best with the cookie task (F1-score: 0.67, confidence interval [0.47-0.86] (p\u2009\u2266\u20090.001)). They also best detected depression with the red-riding hood (F1 score 0.66, [0.45-0.87], p\u2009\u2266\u20090.001), apathy with the joy task (0.60, [0.39-0.81], p\u2009\u2266\u20090.001), but not irritability. LASER features best detected OCB (0.65, [0.45-0.84], p\u2009\u2266\u20090.001), depression (0.60, [0.40, 0.80], p\u2009\u2266\u20090.01) and apathy (0.61, [0.37, 0.86], p\u2009\u2266\u20090.001) from the red-riding hood task, but not irritability. Acoustic features best detected depression (0.63, [0.46, 0.80], p\u2009\u2266\u20090.001) and OCB (0.60, [0.43, 0.77], p\u2009\u2266\u20090.001) but not apathy nor irritability. This study showed that speech analyses can detect obsessive/compulsive behaviors, depression, and apathy in HD participants but not irritability. Linguistic and LASER features provided the most consistent detections, but acoustic features also detected depression and OCB, highlighting their complementary role for psychiatric characterization in HD.\n\nID: 42363493\nTitle: Metaheuristic-driven machine learning study for early detection and classification of Parkinson's disease using feature prioritization with pelican optimization algorithm.\nAbstract: Parkinson disease (PD) is a degenerative disorder of the brain and afflicts approximately 6 in 10 people aged 50 years or older. PD patients have motor and speech problems, so regular visits to and monitoring of the patients are hard. It is necessary to detect the presence of PD promptly and accurately, since early treatment will contribute greatly to enhancing patients' lives. As the number of aging people increases, there is a great demand for noninvasive, reliable, and remote diagnosis. In the current work, we studied 31 patients with PD and healthy subjects, their voice recordings, to create an automatic classification system. A Light Gradient Boosting Machine (LightGBM) classifier was adapted and boosted using metaheuristic-based feature selection (FS), namely the Pelican Optimization Algorithm (PAO). Hyperparameter optimization was made to optimize predictive performance. The models have been assessed on typical classification measures, i.e., accuracy, sensitivity, specificity, precision, and AUC. We classified using the baseline LightGBM classifier, with an accuracy of 95%. The resulting model had a better prediction accuracy of 97% after using PAO-based FS and hyperparameter optimization. More than that, the model was also sensitive, specific, precise, and had a high area under the curve, which validates its effectiveness at classifying PD. The paper shows that FS and hyperparameter tuning are effective approaches when applied to voice data and combined with LightGBM to detect PD as early as possible. The results point to the promise of noninvasive diagnostic systems based on the use of telemedicine to allow early intervention and enhance the lives of people with PD.\n\nID: 42358974\nTitle: Successful rescue therapy with eculizumab for probable tislelizumab-related MMM overlap syndrome with dual positivity for anti-acetylcholine receptor and anti-titin antibodies: a case report and literature review.\nAbstract: While immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment, they can trigger diverse immune-related adverse events (irAEs). Among these, ICI-related myocarditis, myositis and myasthenia gravis (MMM) overlap syndrome (ICI-MMM) is a rare but potentially fatal complication. Conventional immunotherapy often exhibits limited efficacy against ICI-MMM, which is associated with high mortality rates. Thus, there is an urgent need for novel and effective strategies to mitigate its life-threatening outcomes. We conducted a retrospective analysis of the successful rescue use of eculizumab in a patient with tislelizumab-related MMM overlap syndrome who tested seropositive for both anti-acetylcholine receptor (AChR) and anti-titin antibodies. We also performed a focused systematic literature review on the use of complement inhibitor therapy for ICI-related myasthenia gravis and its overlap syndrome. A 64-year-old male developed ptosis and tetraparesis two weeks following the second infusion of tislelizumab for lung adenocarcinoma. Serological testing revealed dual positivity for anti-AChR antibody and anti-titin antibody. Tislelizumab was immediately withdrawn, and the patient was treated with corticosteroids and intravenous immunoglobulin as first-line therapy. However, his clinical condition deteriorated rapidly, and new symptoms emerged, including chest pain, muscle pain, dysphagia, slurred speech, and dyspnea. Although the absence of histopathological confirmation for myocarditis and myositis, the clinical, laboratory, electrophysiological, and cardiac imaging findings supported the diagnosis of probable ICI-MMM. Rescue therapy with eculizumab was commenced (900 mg weekly for four doses), eliciting rapid and marked clinical improvement. The patient ultimately achieved minimal symptom expression without any exacerbation. This is the first reported case of successful eculizumab rescue treatment for probable tislelizumab-related MMM overlap syndrome with dual seropositivity. Our finding suggests eculizumab may represent a promising rescue option for ICI-MMM warranting prospective evaluation.\n\nID: 42356806\nTitle: Enhancing Early Detection of Alzheimer's Disease: An Ensemble Model for Multi-Domain Cognitive Assessment Using Voice and Video.\nAbstract: Accurate early screening of Alzheimer's disease (AD) is crucial, yet traditional diagnostic methods are often limited by invasiveness or high costs. Therefore, there is a critical need for non-invasive biomarkers that enable precise and accessible screening. In this study, we propose a multi-modal digital biomarker framework designed to accurately detect AD by evaluating impairments across multiple cognitive domains, such as language, working memory, and visuospatial attention. By leveraging voice and video data, our approach significantly enhances user accessibility and real-world applicability. We validated the proposed framework using a dataset of 128 participants, comprising 77 healthy controls (HCs) and 51 patients with AD. While individual cognitive tasks yielded F1-scores ranging from 69.23% to 77.78% and sensitivities from 69.23% to 80.77%, our ensemble strategy significantly enhanced detection performance, achieving an F1-score of 83.64% and a sensitivity of 88.46%. These findings confirm that the proposed multi-modal digital biomarker framework, enhanced via ensembling, provides a highly accurate, scalable, and practical solution for the non-invasive screening and detection of AD.\n\nID: 42320943\nTitle: Functional recovery strategies in progressive supranuclear palsy with cerebellar predominance.\nAbstract: This report details a case of a patient in his 60s who exhibited ataxic gait, frequent falls, limb incoordination, tremors and rigidity, leading to a diagnosis of progressive supranuclear palsy with cerebellar predominance (PSP-C). Clinical assessment indicated slurred speech, increased muscle tone, deep tendon reflexes that were mildly reduced asymmetrically on the left side and reduced strength, while sensations remained intact. PSP-C is an uncommon variant of PSP often misidentified as multiple system atrophy-cerebellar type (MSA-C) because of shared characteristics. The patient participated in a comprehensive physiotherapy programme that included transfer training and promotion of independence in activities of daily living while also targeting rigidity and tremors. This case illustrates the diagnostic difficulties associated with addressing motor impairments, fall prevention and improving quality of life in a condition with few treatment alternatives.\n\nID: 42318897\nTitle: Digital speech-based markers to advance prognosis in Alzheimer's disease.\nAbstract: Validated prognostic tools are essential to advance drug development and clinical care in Alzheimer's disease, particularly as the field shifts toward the prevention of cognitive decline. While progress has been made in developing blood-based biomarkers for the early detection of amyloid pathology, amyloid positivity alone does not reliably predict progression to symptomatic disease. Digital markers can serve as complementary prognostic tools to inform early intervention strategies. Among digital markers, speech-based markers offer a scalable, non-invasive, and cost-effective approach to predicting and monitoring cognitive decline. However, the development of validated speech-based tools has been constrained by the lack of large, multilingual datasets with longitudinal sampling, deep phenotyping, harmonized clinical and biomarker data, and adequate representation of preclinical populations. SpeechDx is a 3-year, multinational, multilingual observational study (n\u00a0=\u00a02006) designed to address these gaps and accelerate the development of speech-based tools to inform early risk assessment, enable timely intervention, and guide personalized care.\n\nID: 42309086\nTitle: Safety and efficacy of staged, bilateral magnetic resonance-guided focused ultrasound pallidothalamic tractotomy for motor complications of Parkinson's disease: a prospective, multicentre, single-arm trial.\nAbstract: Parkinson's disease management is often complicated by motor fluctuations and dyskinesia. Although deep brain stimulation addresses these symptoms, its use is limited by invasiveness, potential device failure, and the need for ongoing maintenance. Magnetic resonance-guided focused ultrasound (MRgFUS) provides incisionless, image-guided ablation as an alternative. However, the benefits and harms of staged, bilateral MRgFUS pallidothalamic tractotomy have not been evaluated systematically in prospective multicentre studies. In this prospective, multicentre, single-arm study, adults with idiopathic, levodopa-responsive Parkinson's disease and motor complications (Movement Disorders Society Unified Parkinson's Disease Rating Scale [MDS-UPDRS] part IV item 4.2 or 4.4 score \u22652) were enrolled at nine investigational centres (six in the USA, two in Spain, and one in Taiwan). Participants underwent unilateral MRgFUS pallidothalamic tractotomy to the symptom-dominant side. Contralateral pallidothalamic tractotomy followed a minimum of 6 months later for participants meeting prespecified criteria. The primary efficacy endpoint was percent change from baseline to 3 months after the second procedure in the summed MDS-UPDRS part III off-medication upper and lower extremity (ULE) motor scores. Safety outcomes were incidence, severity, and persistence of treatment-related adverse events in the 12 months after each procedure. Safety and efficacy of unilateral treatment were evaluated in the unilateral intention-to-treat (ITT) and safety populations, defined as all patients receiving one or more sonications during the first procedure. The primary outcome and safety of bilateral treatment were evaluated in the bilateral modified ITT (mITT) and safety populations, which required one or more sonications during the second procedure, a baseline motor assessment, and at least one post-bilateral motor assessment. This trial is registered at ClinicalTrials.gov, NCT04728295 and is active, not recruiting. Between July 12, 2021, and Nov 1, 2023, 54 patients received unilateral treatment and 40 proceeded to bilateral treatment (63 [67%] were male and 31 [33%] were female) and were included in the primary analysis; 36 completed 12-month follow-up after the second procedure. Median bilateral ULE motor scores decreased from 33\u00b70 points (IQR 28\u00b70-40\u00b75) at baseline to 21\u00b70 points (15\u00b70-25\u00b75) at month 3 post-bilateral treatment, a median within-patient change of 10\u00b75 points (5\u00b77-20\u00b70), representing a 32% (18-52) improvement (p<0\u00b70001). Benefits became apparent within 1 month of the first procedure and lasted through to 12 months after the second procedure. Treatment-related adverse events occurred in 21 (39%) of 54 patients after unilateral treatment; one (2%) had a persistent moderate adverse event at 6 months. After bilateral treatment, 22 (55%) of 40 patients had treatment-related adverse events; ten (25%) had persistent moderate or severe adverse events at 12 months, mainly affecting speech, gait, and balance. One (3%) patient developed severe persistent anarthria. Unilateral MRgFUS pallidothalamic tractotomy demonstrated safety and efficacy for Parkinson's disease motor complications; however, bilateral treatment offered small motor gains while increasing persistent moderate or severe adverse events. Post-bilateral treatment complications in speech, gait, and balance are consistent with historical data for bilateral ablative procedures for movement disorders. Although unilateral MRgFUS pallidothalamic tractotomy was beneficial in our study, bilateral procedures demand rigorous patient selection and counselling regarding cumulative risks.

Recent work has demonstrated highly accurate intracortical BCIs for speech and cursor control, but two critical capabilities needed for practical viability were unmet: independent at-home operation without researcher assistance and reliable long-term performance supporting accurate speech and cursor decoding. Here we demonstrate the independent and near-daily use of a multimodal BCI with novel brain-to-text speech and computer cursor decoders by a man with paralysis and severe dysarthria due to amyotrophic lateral sclerosis. Over nearly 2\u2009years, the participant used the BCI for more than 3,800\u2009h at home with no researchers present to maintain rich interpersonal communication with his family and friends, independently control his personal computer and sustain full-time employment-despite being paralyzed. He communicated 183,060 sentences-totaling 1,960,163 words-at an average rate of 56 words per minute. He labeled 92% of sentences as being decoded at least mostly correctly. In formal quantifications of performance where he was asked to say words presented on a screen, attempted speech was consistently decoded with more than 99% word accuracy (125,000 word vocabulary). The participant also used the speech BCI as keyboard input and the cursor BCI as mouse input to control his personal computer, enabling him to send text messages and emails and to browse the internet. These results demonstrate that intracortical BCIs have the potential to support independent use in the home, marking a critical step toward practical assistive technology for people with severe motor impairment.\n\nID: 42274996\nTitle: A Machine Learning Approach to Voice-Based Parkinson Disease Screening Using Multiview Spectrogram and Speech Recognition Features: Diagnostic Study.\nAbstract: Parkinson disease frequently manifests early vocal impairment, motivating the development of noninvasive and scalable digital screening tools. This study proposes a multiview spectrogram-based deep learning framework integrating recognition-aware context for Parkinson disease detection from voice recordings. Voice recordings from 203 participants (121 with Parkinson disease and 82 healthy controls) were collected prospectively. Three spectrogram representations (Mel, short-time Fourier transform, and constant-Q transform) were extracted and processed through parallel convolutional neural network branches. A recognition ratio (RR) feature vector derived from automatic speech recognition transcript agreement was optionally fused with spectrogram embeddings. Models were evaluated using strict subject-wise 5-fold cross-validation. Multiview spectrogram recognition-aware Parkinson detection network achieved a mean test accuracy of 86.9% (SD 25.2%) using 3-view spectrogram fusion, improving to 97.4% (SD 5.7%) when incorporating the RR feature. RR integration reduced the false negative rate by approximately 84.5%, substantially improving sensitivity in screening-oriented settings. Combining multiview spectrogram learning with recognition-aware context significantly enhances voice-based Parkinson disease classification under leakage-free evaluation. These findings support the potential of this approach for noninvasive screening in structured recording settings, while further validation in diverse real-world environments is needed.\n\nID: 42268776\nTitle: Validating automated speech timing methods in clinical and healthy speakers across sentence, paragraph, and monologue tasks.\nAbstract: Automated measurement of speaking and articulation rates holds promise as a scalable alternative to manual analysis in clinical populations. This study evaluated a Praat-based script that estimates global speech timing by detecting syllable nuclei via amplitude dips. Speaking rate (syllables/total duration) and articulation rate (syllables/speaking time) were measured manually and with an automated script across speakers with multiple sclerosis (MS), Parkinson's disease (PD), and healthy controls. Sixty participants (20 per group) completed sentence, paragraph, and monologue tasks (N\u2009=\u2009180 recordings). Default script parameters were compared to an optimized version with manually tuned dip thresholds. Analyses included error metrics, linear mixed-effects models, and generalizability analysis. Automated speaking rate measures showed strong correlations with manual measures across all groups and tasks (r\u2009=\u20090.623-0.998). However, default automated estimates underestimated both speaking and articulation rates, especially in clinical speakers and for the monologue task. Articulation rate was more sensitive to the measurement method, which accounted for nearly half of the total variance. Optimization of the Praat script parameters reduced proportional error by \u223c60%, with varying effects across groups. Findings suggest that optimized automated methods can improve measurement accuracy, but population- and task-specific challenges persist, especially for articulation rate in MS and PD speakers.\n\nID: 42243620\nTitle: Documented follow-up to memory concerns reported at the Medicare Annual Wellness Visit.\nAbstract: The Medicare Annual Wellness Visit (AWV) may improve timely detection of Alzheimer's disease and related dementias (ADRD), yet little is known about the frequency of follow-up on patient-reported memory concerns during the AWV. We use electronic medical record (EMR) data from an academic health system to examine EMR-documented follow-up actions for patients with newly reported memory concerns on the AWV health risk assessment, including formal cognitive assessment or specialist referrals. The 1411 patients with newly reported memory concerns were predominantly white (70%) and female (63%), with an average age of 78 (SD 7.5). At the AWV, few patients received a cognitive assessment (5.4%; n\u00a0=\u00a076), specialist referral (2.1%; n\u00a0=\u00a030), or both (0.4%; n\u00a0=\u00a06). In adjusted analyses, we did not observe statistically significant differences by sociodemographic characteristics. This EMR-based study highlights an opportunity to better leverage the AWV to improve ADRD detection and care.\n\nID: 42216192\nTitle: Multidimensional cognitive deficit in logopenic variant primary progressive aphasia: a case report.\nAbstract: Logopenic variant primary progressive aphasia (lvPPA) is a language-led presentation of Alzheimer's disease that is easily overlooked in older patients with vascular and systemic comorbidities. We report a 78-year-old right-handed Asian woman with hypertension, diabetes, hepatic cirrhosis, and coronary artery disease who developed insidious word-finding difficulty progressing to severe anomia, impaired sentence repetition, and multidomain cognitive decline. Serial Indonesian MMSE, MoCA-Ina, Consortium to Establish a Registry for Alzheimer's Disease (CERAD), and Tes Afasia untuk Diagnosis, Informasi, dan Rehabilitasi (TADIR) assessments showed early amnestic and executive deficits followed by dominant phonological and naming impairment, while MRI revealed left-predominant temporo-parietal and medial temporal atrophy with small-vessel white matter disease, consistent with mixed Alzheimer and vascular pathology. She received donepezil, low-dose clobazam, and targeted speech-language and cognitive rehabilitation with partial symptomatic benefit. This case highlights the importance of detailed language assessment and culturally adapted neuropsychological batteries to identify lvPPA within mixed dementia in resource-limited settings.\n\nID: 42208123\nTitle: Advancing Alzheimer Disease Prediction With Large Language Model-Based Linguistic Feature Analysis: Development and Validation Study.\nAbstract: Alzheimer disease (AD) is a progressive neurodegenerative disorder with rapidly growing global prevalence. Early detection is critical for timely intervention; yet, conventional diagnostic methods remain costly and invasive. Speech-based assessment has emerged as a noninvasive alternative, as AD characteristically impairs linguistic abilities including fluency, coherence, and informational content. Recent advances in large language models (LLMs) offer new opportunities to extract structured linguistic features from transcribed speech for automated AD classification. However, existing LLM-based approaches often lack transparency and clinical interpretability, limiting their adoption in clinical workflows. This study aims to investigate the influence of linguistic features extracted from transcribed speech, as analyzed by LLMs, on the accuracy and interpretability of AD prediction. We propose a framework that leverages LLMs to analyze linguistic features extracted from transcribed speech for AD classification. Our approach focuses on 4 key aspects, including readability, fluency, richness of detail, and keyword relevance. To enhance classification accuracy, the framework integrates transcript embeddings with feature explanation embeddings, forming a comprehensive linguistic representation. We conducted extensive ablation studies to evaluate the contributions of individual features and benchmarked our framework against existing LLM-driven methodologies through pairwise explainability evaluations. Output stability was assessed across 3 independent pipeline runs. A fully local configuration (Llama 3 8B + nomic-embed-text) was tested to evaluate privacy-preserving deployment feasibility. Explainability was assessed via LLM-based pairwise comparison (Gemini-3.1-flash-lite) against the method of Bang et al across 54 correctly classified cases and by blinded evaluation from 2 neurologists. The proposed framework achieved a mean precision of 91.52%, a sensitivity of 91.08%, a specificity of 96.29%, and F1-score of 91.05% across 3 independent runs on the ADReSSo 2021 dataset, outperforming existing LLM-based approaches. A fully-local configuration (Llama 3 8B+nomic-embed-text, requiring no cloud application programming interface access) achieved an F1-score of 81.58%, demonstrating framework transferability to privacy-preserving deployment environments. Keyword relevance was the most influential feature (F1-score drop of 13.22 pp when removed). Explainability evaluations showed our method was preferred in 49 out of 54 cases via Gemini-3.1-flash-lite, with human experts preferring our method in 89 of 108 blinded assessments. These findings highlight that a structured linguistic feature analysis using LLMs provides a robust and interpretable framework for preliminary AD detection. Our approach offers a scalable and accessible solution that bridges artificial intelligence-driven text analysis with clinical applications, supporting early detection of cognitive decline through noninvasive assessment methods.\n\nID: 42202251\nTitle: Beyond Time Saved: Implementation, Equity, and the Utility Threshold for Nursing AI Scribes.\nAbstract: Schwabe et al's pre-post time-motion study of a domain-specific artificial intelligence (AI) speech assistant used by nurses in German long-term care provides one of the few real-world, full-shift evaluations of an AI scribe deployed to a nonphysician workforce, with paired objective observation and self-reported outcomes. This commentary points to the implications of these findings that extend well beyond the time savings headline. The study reports substantial reduction in self-reported documentation time and increased satisfaction with the documentation system, yet workplace satisfaction and the perception that AI scribes are \"a good idea to implement\" did not improve. Taken together, these findings show three undertheorized issues for AI scribe implementation in nursing and long-term care. First, postimplementation increases in time spent reviewing entries and retrieving information indicate that AI scribes redistribute cognitive effort from authoring to verification, with unknown consequences for satisfaction, mastery, and error detection. Second, the apparent paradox of rising documentation satisfaction alongside falling expectations of AI quality represents user calibration. Third, the substantial equity considerations of automatic speech recognition documentation reflect a broader trend of AI scribe studies that treat equity as a caveat, rather than treating equitable performance as empirically measurable and testable across variations in linguistic styles, dialects, and social linguistic dimensions. To advance the field, the next generation of nursing AI scribe research must treat documentation as a heterogeneous bundle of authoring, reviewing, retrieving, and verifying activities with distinct satisfaction and error profiles; specify and validate end-user-defined anchor utilities, rather than having a narrow focus on diffuse improvement; and treat equity testing and reporting of both automatic speech recognition systems and workforce adoption as standard reporting expectations, rather than caveats.\n\nID: 42187040\nTitle: Non-verbal dichotic listening: A new cognitive hearing test for dementia.\nAbstract: Central hearing difficulties are a feature of Alzheimer's disease (AD) but not well captured by standard speech perception tests. We developed a non-verbal dichotic listening test (NVDLT) based on everyday sounds, and compared this with a standard verbal dichotic listening test (VDLT) in 36 people with primary progressive aphasia (PPA), 18 with typical AD (tAD), 6 with right temporal-variant frontotemporal dementia (rtvFTD), and 29 cognitively-healthy controls. Daily-life hearing function was assessed using the modified Amsterdam Inventory for Auditory Disability and Handicap (mAIAD). On NVDLT, all dementia groups except rtvFTD performed worse than controls; tAD, logopenic-variant PPA and nonfluent/agrammatic-variant PPA performed worse than rtvFTD. NVDLT performance predicted atrophy in the retrosplenial cortex and hippocampus. NVDLT score discriminated tAD patients from controls with near-perfect accuracy (area under the curve [AUC]\u00a0=\u00a00.99) and predicted daily-life hearing function (r\u00a0=\u00a00.57). NVDLT performance indexes daily-life hearing function and may aid dementia diagnosis, potentially in culturally-diverse populations.\n\nID: 42184217\nTitle: Detecting Cognitive Impairment Early in Hispanic and Black Older Adults: Community Voices From South Central Texas.\nAbstract: Alzheimer disease and related dementias (ADRD) are more prevalent in Black and Hispanic older adults and are also more likely to be undetected and misdiagnosed. The purpose of this study was to engage with Black and Hispanic communities about interest in and support needed for memory screening. Participants were recruited from established community partners of the South Texas Alzheimer's Disease Research Center to engagein a 90-minute listening session. The session was recorded with participants' permission, and a thematic analysis was conducted by 2 independent coders. Sixteen individuals (81% female, 88% Hispanic or Black) from various perspectives participated (eg, health care workers, persons with dementia, caregivers). Four core themes emerged: building trust, access and time barriers, community-specific literature, and representative messengers. Trust was noted to be foundational, encompassing who delivers the screening and where it takes place. Transportation, time burden, competing caregiving responsibilities, work schedules, and limited access to technology/internet were key barriers. The need to create accessible and relatable literature and videos tailored to diverse educational levels and cultural backgrounds was also emphasized. Trusted members of the community could be accepted to perform memory screenings and provide education. Partnering with faith-based organizations, senior centers, and other community hubs would help overcome barriers to screening.\n\nID: 42174309\nTitle: A Patient-Reported Outcome Measure of Communication Difficulties in Friedreich Ataxia: COMATAX.\nAbstract: Friedreich ataxia (FA) causes progressive impairment of communication due to gradual deterioration of speech, associated with impaired hearing, socio-cognitive and language skills. There is an urgent need to investigate the impact of this multiparametric alteration on patients' lives. Therefore, the COMunication and ATAXia measure (COMATAX) was developed and validated in French and German. In the PROFA study (NCT05943002), we conducted focus groups and cognitive interviews with patients with FA, professionals and caregivers to elaborate relevant items of communication disabilities. Subsequently, the measure was validated in 93 patients with FA via a mobile health app. For validation, distribution properties, reliability (Cronbach's alpha) and validity (correlations with VHI-30, SSQ-12, SARA total score, SARA speech item, Speech rate and GAA repeats; known-groups validity by age, sex, and self-rated health/wellbeing, disease-severity, hearing function, daily activities, and exploratory factor analysis) were calculated. An IRT analysis was performed to assess item characteristics. COMATAX consists of 17 items (five response options each) and an 18th question asking about the most bothersome symptom. We observed high internal consistency for the total COMATAX scale (\u03b1\u2009=\u20090.897), strong correlations with VHI-30 (r=.894), SSQ-12 (r\u2009=\u2009-.531), moderate with SARA score (r=.498), SARA speech item (r=.416), Speech rate (r=-.354), weak with GAA repeat length (rGAA1=-0.207) and the ability to distinguish between different subgroups (disease severity, self-rated health, wellbeing, hearing function, and daily activities). Most items showed good discrimination of communication ability. The COMATAX is a valid and reliable patient-reported communication disability measure, useful in future therapeutic trials in FA.\n\nID: 42171798\nTitle: A machine learning-derived speech index as a biomarker for Huntington's disease severity.\nAbstract: The development of disease-modifying therapies for Huntington's disease (HD) necessitates sensitive, scalable, and objective biomarkers for patient stratification and tracking. Current clinical scales are rater-dependent and time-consuming, while neuroimaging is costly and inaccessible. We aim to develop and validate a novel Speech Index, derived from automated acoustic analysis, to stratify HD stages and predict the severity of disease. We recruited 141 HTT gene carriers (37 premanifest, 104 manifest HD) and 69 healthy controls. Participants read a standardized passage, and the recordings were processed to extract 28 speech features. A composite Speech Index was constructed using Bootstrap LASSO Regression for feature selection. Its performance was validated against the HD stages, clinical scale scores and the volume of the caudate and putamen from MRI. The Speech Index significantly increased across HD stages (p\u2009<\u20090.001). The Index showed strong correlations with clinical measures (cUHDRS: \u03c1\u2009=\u2009-0.67; TMS: \u03c1\u2009=\u20090.57; SDMT: \u03c1\u2009=\u2009-0.63; all p\u2009<\u20090.001) and neuroimaging biomarkers (caudate: \u03c1\u2009=\u2009-0.55; putamen: \u03c1\u2009=\u2009-0.62; all p\u2009<\u20090.001). Generalized additive models confirmed the Index's high predictive value for these outcomes (pseudo-R2 from 0.430 to 0.596). We developed a fully automated, interpretable Speech Index that serves as a valid digital biomarker for HD severity. It holds promise for remote monitoring, clinical trial enrichment, and objective assessment of therapeutic efficacy.\n\nID: 42166472\nTitle: Prediction of cognitive impairment through speech data analysis: A comparative evaluation of deep learning models.\nAbstract: The early detection of cognitive impairments, such as mild cognitive impairment (MCI) and Alzheimer's disease (AD), is essential for timely intervention and management. This study evaluates the performance of various deep-learning models in classifying speech recordings from individuals with normal cognition (NC), MCI, and AD, to identify the most effective approach for audio-based cognitive impairment diagnosis. Speech data were obtained from the AI Hub \"Cognitive Impairment Diagnosis Voice/Conversation\" dataset. The study analyzed voice recordings from 320 female participants (105 with Alzheimer's disease, 92 with mild cognitive impairment, and 123 cognitively normal controls). Three deep-learning architectures were compared: a one-dimensional convolutional neural network (1D CNN), an audio spectrogram transformer (AST), and a speech recognition model (Wav2Vec 2.0). The models were trained using features such as spectrograms, mel-spectrograms, and mel-frequency cepstral coefficients (MFCCs). Model performance was assessed using accuracy, recall, precision, and F1-score, with a five-fold cross-validation strategy to ensure robust and unbiased evaluation. Statistical significance was assessed using pairwise proportion z-tests with Holm-Bonferroni correction, and Wilson score 95% confidence intervals were computed for each model's accuracy. Wav2Vec 2.0 outperformed the other models, achieving the highest accuracy and F1-scores for NC vs. MCI (accuracy: 0.74, F1: 0.72) and NC vs. AD (accuracy: 0.83, F1: 0.83). Pairwise proportion z-tests with Holm-Bonferroni correction confirmed that Wav2Vec 2.0 significantly outperformed 7 of 10 competing models (corrected p\u2009<\u20090.05) in both classification tasks. Performance varied by model and classification task, with Wav2Vec 2.0 consistently demonstrating superior accuracy across labels. This study emphasizes the importance of selecting appropriate models and features for task-specific optimization and provides a foundation for developing non-invasive, speech-based diagnostic tools for cognitive disorders.\n\nID: 42156531\nTitle: Use of machine learning and voice for multiclass classification of Parkinson's disease, chronic obstructive pulmonary disease, and healthy controls.\nAbstract: Parkinson's disease (PD) and chronic obstructive pulmonary disease (COPD) are prevalent conditions with substantial impact on quality of life and health care systems. Both disorders affect voice production through different physiological mechanisms, yet neither condition has a widely adopted objective biomarker for routine clinical use. Voice analysis has emerged as a non-invasive digital biomarker candidate, but existing studies have largely focused on binary classification within a single disorder or language. This study aimed to evaluate whether an unified multiclass machine learning (ML) framework applied to sustained vowel \"a\" phonation can discriminate between PD, COPD, and healthy controls (HC) across linguistically distinct cohorts. Sustained vowel recordings were analyzed from Swedish speaking individuals with COPD and HC, and English-speaking individuals with PD and HC, collected under comparable mobile recording conditions. Acoustic features included baseline voice measures and Mel Frequency Cepstral Coefficients. A soft voting ML framework integrating support vector machine, random forest, CatBoost, and light gradient boosting classifiers was trained using nested cross validation with hyperparameter optimization. Data were partitioned at the participant level into a development cohort and an independent test cohort. Model performance was evaluated using accuracy, macro averaged precision, recall, F1 score, receiver operating characteristic analysis, and confusion matrices. Model interpretability was assessed using Shapley additive explanations and vowel space analysis. The final soft voting classifier achieved robust multiclass discrimination on the participant disjoint independent test set, with an overall accuracy of 0.842 and a macro averaged F1 score of 0.839. Classification performance differed across groups, with the highest performance observed for PD, intermediate performance for HC, and lower performance for COPD. Misclassifications occurred primarily between HC and COPD, while confusion between PD and COPD was minimal. Feature attribution analysis revealed class dependent relevance patterns, and vowel space analysis demonstrated subtle but consistent group level differences. These findings demonstrate the feasibility of using an explainable soft voting machine learning framework applied to sustained vowel phonation to distinguish between neurologically and respiratory driven voice impairments across linguistic contexts. The study supports voice as a promising digital biomarker modality for multiclass clinical discrimination using mobile recordings.\n\nID: 42422850\nTitle: Improving respiratory disease detection through SSL-enhanced acoustic analysis and exercise-rest measurements.\nAbstract: Voice analysis has emerged as a promising non-invasive approach for monitoring respiratory and systemic health conditions. However, subtle physiological alterations are often difficult to capture using recordings collected at rest. In addition, combining traditional acoustic descriptors with modern self-supervised speech representations may provide complementary information for clinical voice analysis. This study evaluates a generalized screening model integrating stress-induced acoustic analysis with machine learning. We investigate how physical exertion and the fusion of traditional acoustic features with self-supervised learning embeddings (such as wav2vec 2.0 and WavLM) enhance the diagnostic sensitivity of vocal and respiratory signals. Post-Acute Sequelae of SARS-CoV-2 (PASC) is used as a case study to evaluate the proposed framework. Utilizing the DICOPERIA-Voice dataset (n = 154), we collected recordings of sustained vowel phonation (/a/) and voluntary coughing at two clinical moments: resting state and following a physiological stress protocol (six-minute walk and one-minute sit-to-stand tests). We employed a dual-feature extraction strategy, combining traditional acoustic biomarkers with high-dimensional Self-Supervised Learning (SSL) embeddings from wav2vec 2.0, WavLM and HuBERT. Binary classification (PASC vs. Healthy) was performed using Logistic Regression, evaluated via stratified 5-fold cross-validation. Physical exertion significantly improved classification performance and reduced model variability across all tasks. The fusion of acoustic features, WavLM and wav2vec 2.0 achieved peak F1-scores of 82.2% for vowel phonation and 80.8% for coughing both in post-exercise conditions. A cross-task late fusion model aggregation reached the highest overall performance, with an F1-score of 87.7%. Incorporating Self-Supervised Learning representations into acoustic analysis improves the sensitivity of voice-based screening, while post-exercise measurements further enhance the robustness and consistency of classification. Together, these strategies provide a scalable and objective framework for detecting respiratory and vocal sequelae in chronic or post-viral conditions. With further validation, this approach could be integrated into routine functional assessments, offering a rapid, non-invasive adjunct to clinical decision-making.\n\nID: 42421997\nTitle: Neoadjuvant Docetaxel/Cisplatin/5-Fluorouracil Enabling Laryngeal Preservation in Cervical Esophageal Carcinosarcoma: A Case Report.\nAbstract: Esophageal carcinosarcoma is a rare malignancy comprising both epithelial and mesenchymal components, for which no standard treatment has been established. Organ preservation in cervical esophageal malignant tumors is particularly challenging because curative resection often necessitates laryngectomy. We describe a cervical esophageal carcinosarcoma that responded markedly to neoadjuvant docetaxel/cisplatin/5-fluorouracil (DCF), permitting laryngeal preservation, with a brief literature context. A woman in her 50s presented with discomfort on swallowing. Upper endoscopy identified a type-1 polypoid tumor on the posterior wall 18 cm from the incisors, with involvement near the esophageal inlet at 17 cm. Biopsies showed a spindle-cell-predominant tumor; immunohistochemistry (cytokeratin AE1/AE3, p63) demonstrated an admixed epithelial component, supporting a diagnosis of esophageal carcinosarcoma. Contrast-enhanced CT revealed an approximately 6.5-cm exophytic lesion in the cervical to upper thoracic esophagus, and PET-CT showed intense uptake (maximum standardized uptake value 15.3). Clinical staging was cT3N0M0, cStage II (UICC TNM 8th edition). Two cycles of neoadjuvant DCF induced a dramatic response, leaving only a subtle ~5-mm proximal extension toward the right posterior wall. The patient underwent robot-assisted thoracoscopic subtotal esophagectomy with 3-field lymphadenectomy, followed by gastric conduit reconstruction through the posterior mediastinal route with cervical esophagogastric anastomosis using a 23-mm powered circular stapler. Intraoperative iodine staining delineated the proximal margin, and laryngeal preservation was achieved. Pathology showed pT1b-SM1, pN0, M0, pStage I with treatment-effect grade 1a, and the proximal resection margin was negative. Histology demonstrated a continuous transition between atypical squamous cells and spindle sarcomatous elements; the sarcomatous component exhibited inflammatory infiltrates predominantly composed of lymphocytes and foamy histiocytes, with focal hyalinization, consistent with a therapeutic effect. The postoperative course was uneventful, and the patient was discharged on day 16. No adjuvant therapy was administered. At 12 months of follow-up, no evidence of recurrence or metastasis has been observed. This rare case illustrates that neoadjuvant DCF can downstage cervical esophageal carcinosarcoma and enable curative, larynx-preserving resection. Such responses support consideration of neoadjuvant chemotherapy as a strategy for functional preservation in selected patients with this histology.\n\nID: 42416755\nTitle: Subglottic Mucormycosis and Invasive Candidiasis in Uncontrolled Diabetes Mellitus - a Case Report with Review of the Literature.\nAbstract: Mucormycosis is an opportunistic infection caused by fungi of the order Mucorales and Candida is a yeast which is the most common cause of fungal infections in humans. The most commonly known risk factor for these fungal infections is uncontrolled diabetes mellitus (DM), followed by other causes of immunosuppression like neutropenia and corticosteroid therapy. In atypical clinical presentations, all differential diagnosis should be considered, and followed by histopathological and microbiological examination for diagnosis of fungal infections like mucormycosis and candidiasis in uncommon locations. Early diagnosis and combined medical and surgical treatment, along with resolution of the associated risk factors can lead to effective results and good prognosis.\n\nID: 42414035\nTitle: Bilateral vocal cord paralysis in multifocal motor neuropathy.\nAbstract: We present a case of a male in his fifties who attended with wheezing, dysphonia and shortness of breath. He was under investigation for asymmetrical muscle weakness in the absence of a sensory deficit for the preceding 1 year. Spirometry (flow volume loop) suggested extra-thoracic restriction and bronchoscopy confirmed bilateral vocal cord palsy. Due to clinical presentation and a positive anti-GM1, a diagnosis of multifocal motor neuropathy (MMN) with bilateral vocal cord palsy was made. The patient was initiated on intravenous immunoglobulin therapy with good effect on his general muscle weakness and respiratory symptoms, lung function and vocal cord abductor function. MMN with conduction block is a rare autoimmune condition, and vocal cord paresis from bilateral Xth cranial nerve involvement (recurrent laryngeal) is a very rare presentation of an MMN. Early diagnosis led to good patient outcomes.\n\nID: 42411350\nTitle: Evaluation of Electrical Impedance Myography as a Noninvasive Musculoskeletal Biomarker in Infantile- and Late-Onset Pompe Disease.\nAbstract: Patients with infantile- and late-onset Pompe disease (IOPD/LOPD; PD) experience progressive motor deficits. Current methods for assessing muscle health, such as motor tasks or magnetic resonance imaging (MRI), are limited in young or severely affected individuals. This study evaluated electrical impedance myography (EIM) as a noninvasive biomarker of muscle health in PD. Sixty-four participants (11 IOPD, 27 LOPD, 26 healthy controls) were assessed. EIM phase and reactance values were obtained from bilateral limb muscles. Twenty PD participants underwent lower limb musculoskeletal MRI. Participants completed Perceived Stress Scale-10 and Patient-Reported Outcomes Measurement Information System questionnaires. Motor performance was evaluated via balance tests, 9-Hole Peg Test, grip strength, 2-Minute Walk Test, and 4-Meter Walk Test. Participants with PD reported greater impairment in pain intensity, mobility, physical stress experience, and physical function, and performed worse on motor tasks than healthy controls (all p<0.05). EIM phase at 100 and 211 kHz was reduced in participants with PD, particularly in those with IOPD and in pediatric PD participants, compared to healthy controls. Lower phase correlated with higher MRI fat fraction and poorer motor performance. With additional longitudinal investigation, EIM may represent a functionally relevant, noninvasive tool to evaluate disease severity in individuals with PD.\n\nID: 42407303\nTitle: Effect of immunotherapy on seizure severity and spike-wave index in epileptic encephalopathy with spike-wave activation in sleep: The value of EEG spikes in monitoring treatment response.\nAbstract: To evaluate the electrophysiological and clinical effects of intravenous immunoglobulin (IVIg) therapy in children with epileptic encephalopathy with spike-wave activation in sleep (EE-SWAS) and developmental and epileptic encephalopathy with SWAS (DEE-SWAS), and to examine the relationship between spike-wave index (SWI) and clinical treatment response. Thirty-six pediatric patients were prospectively enrolled. SWI was calculated from NREM sleep EEG at baseline, 6 months, and 12 months. Clinical and electroencephalographic (EEG) findings, including spike-wave index (SWI), seizure frequency, functional disability (PEDI), and behavioral status (CBCL) were assessed longitudinally. SWI showed a significant and sustained reduction over time following IVIg therapy (Friedman test, p\u202f<\u202f0.001), with large effect sizes at 6 and 12 months. Seizure frequency decreased and clinical scale scores improved during follow-up. However, multivariable regression analyses demonstrated no significant association between changes in SWI and changes in PEDI or CBCL scores (all p\u202f>\u202f0.05). In addition, change in seizure frequency was not an independent predictor of SWI reduction (\u03b2 = -0.007, 95% CI -0.019-0.006, p\u202f=\u202f0.274). The correlation between SWI reduction and seizure outcome was weak and non-significant (\u03c1 = -0.18, p\u202f=\u202f0.29). IVIg therapy was associated with significant and sustained electrophysiological improvement and is accompanied by clinical improvement in children with EE-SWAS and DEE-SWAS. However, changes in SWI were not significantly correlated with functional, behavioral, or seizure outcomes, suggesting a dissociation between electrophysiological and clinical responses. These findings indicate that SWI should not be considered a standalone biomarker of treatment response and should be interpreted alongside clinical parameters.\n\nID: 42407144\nTitle: Toward a multidisciplinary perspective: Are dental-origin pathologies overlooked in unilateral chronic rhinosinusitis?\nAbstract: To evaluate the prevalence of dental-origin pathologies and dentally related anatomical variants in patients with unilateral chronic rhinosinusitis with or without nasal polyposis undergoing surgical treatment and to explore their association with unilateral nasal polyposis. This prospective study included 107 patients who underwent endoscopic sinus surgery for medically refractory unilateral chronic rhinosinusitis with or without nasal polyposis treated at our institution between January 2024 and March 2025. Patients with a history of previous sinus surgery or malignant disease were excluded. Detailed current and past dental histories were obtained from all patients. Preoperative paranasal sinus computed tomography and magnetic resonance imaging were evaluated for radiological signs possibly related to odontogenic pathology such as periapical lucency, mucosal thickening, or oroantral fistula as well as for anatomical variants such as dental root protrusion into the maxillary sinus. Intraoperatively, pathological specimens were obtained from all patients for histopathological examination. The data were statistically analyzed. Of the 107 patients analyzed, 25 (23%) reported a history of dental disease or intervention involving the adjacent tooth. Periapical radiolucency was identified in 67 patients (63%) and oroantral fistulas in seven patients (6%). Seventy-eight patients (73%) demonstrated radiological evidence of mucosal thickening. Among the 78 patients with radiological findings suggestive of odontogenic involvement, the most common histopathological findings were unilateral inflammatory sinonasal polyps in 41 patients (53%) and chronic inflammatory changes consistent with sinusitis in 26 patients (33%). Antrochoanal polyps were identified in four patients (5%). These findings indicate frequent coexistence of odontogenic and inflammatory sinonasal findings in unilateral disease. Exploratory comparative analysis showed no statistically significant difference in the prevalence of odontogenic findings between patients with unilateral nasal polyposis and those with non-polyp pathologies (Fisher's exact test, p\u00a0=\u00a00.829). Dental-origin pathologies and related anatomical variants appear to be encountered in patients with unilateral chronic rhinosinusitis. These findings suggest a possible association between odontogenic findings and unilateral sinus disease with or without nasal polyposis. A comprehensive dental evaluation and detailed radiological assessment should be considered as part of the preoperative workup. Furthermore, the observed coexistence of unilateral polyposis and odontogenic findings warrants further investigation to clarify the nature of this association.\n\nID: 42404894\nTitle: FcRn antagonist and C5 complement inhibitor as early rescue strategies in severe Myasthenia Gravis: a two-case report.\nAbstract: Myasthenia gravis (MG) is an autoimmune neuromuscular disorder in which approximately 10-15% of patients with generalized AChR antibody-positive MG develop refractoriness to standard immunosuppressive therapies. Advanced therapeutic strategies, including FcRn antagonists and C5 complement inhibitors, have demonstrated early and sustained clinical efficacy in pivotal phase 3 trials. However, evidence supporting their early use in complex clinical scenarios remains limited. We report two cases of severe generalized MG in which early initiation of advanced therapies was associated with rapid clinical stabilization. In the first case, a 75-year-old man with thymoma-associated MG and severe bulbar involvement refractory (MG-ADL: 11) to plasma exchange (PLEX) and intravenous immunoglobulins (IVIg), and unable to continue azathioprine due to adverse events, received off-label efgartigimod preoperatively. Near-complete resolution of bulbar symptoms was observed within 48 hours, enabling robot-assisted thymectomy on day 4 following the first infusion, with sustained neurological improvement at one-month follow-up (MG-ADL score: 2). In the second case, a 74-year-old man with severe refractory bulbar MG requiring nasogastric tube feeding (MG-ADL: 13) and subsequent percutaneous endoscopic gastrostomy (PEG) was treated with ravulizumab after an incomplete response to PLEX, IVIg, corticosteroids, and azathioprine. MG-ADL decreased from 9 at treatment initiation to 5 after two infusions of ravulizumab, and complete recovery of swallowing function allowed PEG removal at 18-week follow-up, with achievement of minimal symptom expression (MG-ADL score: 0). These cases highlight the potential role of early and targeted use of advanced immunotherapies in severe, refractory MG, including as a bridging strategy to thymectomy. Further prospective studies are needed to define optimal criteria and timing for early integration of these agents into the therapeutic algorithm.\n\nID: 42404723\nTitle: A gender-emotion interaction multi-task network for depression recognition via transformer-based multimodal fusion.\nAbstract: Depression is characterized by high prevalence, high recurrence, high disability and high mortality, which seriously affects people's work and life. Among various behavioral biomarkers, speech-based features have gained increasing attention in depression detection due to their non-invasive nature, affordability, and rich capacity for conveying affective states. However, conventional depression recognition approaches rely solely on unimodal acoustic representations and largely overlook the influence of emotion and gender. To address this limitation, this study proposed a gender-emotion interaction multi-task network(G-EIMTNet) for depression recognition via transformer-based cross modal fusion. In the feature fusion stage, the deep representations of Mel-spectrograms were extracted using convolutional neural networks(CNN), and then the Maximum Correlation Minimum Redundancy (MRMR) algorithm was employed to select acoustic higher-order statistical features that were highly correlated with emotions and depressive states. These two types of features were then fused through the transformer attention mechanism. In the depression recognition stage, a depression recognition network for the interaction between gender and emotion was constructed based on a multi-task framework. Experiments on the AVEC2014 dataset showed that this approach outperformed the baseline model by 15.88% and 14.73% in accuracy and F1 score, respectively. Ablation experiments verify the effectiveness of multi-modal fusion and gender-emotion interaction.\n\nID: 42403943\nTitle: Vowel acoustic parameters in speech assessment and rehabilitation of minimally verbal and speech-motor-impaired autistic children: a narrative review.\nAbstract: Speech production difficulties in autism spectrum disorder (ASD) are heterogeneous and are not uniformly characterized by articulatory impairment across the spectrum. However, some autistic subgroups, particularly minimally verbal children, children with low expressive-language ability, and those with suspected co-occurring speech-motor difficulties, may show atypical vowel-acoustic patterns. Because vowel production can be quantified through measures such as formant frequencies, vowel-space area, duration, and variability, these parameters may offer useful objective information for characterizing speech impairment and informing rehabilitation planning in selected phenotypes. This narrative review critically examined the literature on vowel-acoustic characteristics in autistic children and their possible relevance to rehabilitation-oriented systems. Structured searches of PubMed, Scopus, and Web of Science were conducted for studies published up to September 2025. Evidence suggests that some autistic subgroups may exhibit reduced vowel distinctiveness, greater acoustic variability, and atypical temporal or dynamic speech features, although findings are heterogeneous and do not support a single uniform acoustic profile across ASD. Direct intervention evidence remains limited. Most rehabilitation-related studies are small, exploratory investigations, and the available literature is concentrated largely around Auditory-Motor Mapping Training (AMMT), an indirectly relevant speech-motor intervention that reports vowel-related outcomes but does not directly target vowel-acoustic parameters in isolation.Overall, vowel-acoustic measures are better regarded as candidate quantitative tools for subgroup characterization, monitoring, and rehabilitation planning rather than as universal biomarkers across ASD. Their translational potential is promising but remains insufficiently validated, requiring stronger longitudinal, mechanistic, and intervention research before broad clinical application can be justified.\n\nID: 42403145\nTitle: Hoarseness as a Manifestation of Chronic Lymphocytic Leukaemia Involving the Larynx.\nAbstract: Null.\n\nID: 42401192\nTitle: Managing post-extubation dysphagia after prolonged intubation: A systematic review of Speech-Language Pathology (SLP) approaches.\nAbstract: Speech-Language Pathology encompasses the assessment, diagnosis, prevention, and treatment of disorders affecting speech, language, voice, hearing, and swallowing. Among these, dysphagia management is crucial, as safe and efficient swallowing depends on the coordinated action of neuromuscular and anatomical structures within the oropharyngeal, laryngeal, and esophageal systems. Disruption of this coordination, particularly after prolonged intubation, can lead to aspiration, malnutrition, and reduced quality of life. To review the literature on swallowing disorders following prolonged intubation, identify associated risk factors, and describe the main Speech-Language Patathology (SLP) assessment and intervention strategies. A systematic review was conducted on swallowing disorders after prolonged endotracheal intubation using PubMed, BVS, and Cochrane databases. Following PRISMA 2020 guidelines, 266 articles were identified, of which 16 met the inclusion criteria. Risk of bias was assessed with the ROBINS-I and Newcastle-Ottawa (NOS) scales. Most studies showed low risk of bias and moderate methodological quality. Prolonged intubation was consistently associated with dysphagia. Key risk factors included advanced age, neurological conditions, tracheostomy, inflammation, pneumonia, poor functional status, and extended ICU (Intensive care unit) or hospital stays. Dysphagia after prolonged intubation results from multifactorial influences that compromise the swallowing mechanism. Early assessment and targeted Speech-Language Pathology significantly improve swallowing safety, accelerate recovery, and enhance patients' quality of life. These findings highlight the essential role of Speech-Language Pathology (SLP) in post-extubation care and the importance of standardized assessment and rehabilitation protocols.\n\nID: 42398367\nTitle: Preictal reduction in heart rate variability entropy is associated with functional/dissociative seizures and provides modest discrimination from epileptic seizures.\nAbstract: Differentiating functional/dissociative seizures (FDS) from epileptic seizures (ES) remains clinically challenging, with limited electrocardiogram (ECG) biomarker reliability. This study evaluated whether explainable machine learning applied to ECG features could identify autonomic markers for FDS-ES discrimination. ECG recordings from 125 patients with FDS (n\u00a0=\u00a083) or ES (n\u00a0=\u00a042) from two epilepsy centres were analysed. A number of heart rate, HRV, and morphological ECG features was extracted from interictal and preictal segments. Relative-change features were calculated by normalising preictal values to interictal baseline. Classification used Leave-One-Subject-Out Cross-Validation with mutual information filtering, SHapley Additive exPlanations (SHAP)-guided feature selection, class balancing, and hyperparameter tuning. Entropy-based HRV measures were the most consistent discriminative features. In FDS, Sample Entropy, Fuzzy Entropy, and Dispersion Entropy decreased significantly from interictal to preictal states, whereas no significant entropy modulation was observed in ES. Dispersion Entropy showed the strongest contribution across statistical testing, SHAP interpretation, and feature-selection stability. Classification was limited in the interictal condition, and the best performance was obtained using relative-change features: XGBoost achieved 73.5% sensitivity (95% confidence interval [CI]: 62.7-82.6%) and 61.9% specificity (95% CI: 45.6-76.4%). FDS was associated with preictal reduction in HRV entropy, indicating more regular, less complex cardiac dynamics. Within-subject changes appeared to provide more discriminative than static ECG features. Although current performance does not support standalone diagnostic use, entropy-based HRV measures offer interpretable peri-ictal autonomic markers, suggesting visceral changes contribute to FDS emergence.\n\nID: 42397370\nTitle: [A Comprehensive Regional Rehabilitation Program for Children with Hearing Impairments with Active Parental Involvement: The Ivanovo Region Experience].\nAbstract: The problem of hearing impairment in children remains of high medical and social significance, as it negatively affects speech development, social adaptation, and quality of life. Early rehabilitation plays a crucial role, and parental involvement is a key factor in success. In the Russian Federation, ear diseases account for 5% of the structure of childhood disability, necessitating the development of accessible regional rehabilitation programs with active family involvement. To present a comprehensive regional rehabilitation program for children with hearing impairments in the Ivanovo region, developed with the support of the National Medical Research Center for Otorhinolaryngology of the FMBA of Russia, and to describe its main modules aimed at actively involving parents in the process of hearing restoration, speech development, and social adaptation of the child. This work is based on an analysis of the experience of implementing the regional program at the audiology department of the Ivanovo Regional Clinical Hospital with the participation of the Department of Otorhinolaryngology of Ivanovo State Medical University. The description is based on program documentation, session protocols, and interviews with participants (specialists and parents). A qualitative and descriptive analysis was conducted, identifying key modules, rehabilitation stages, and the roles of specialists. The program includes comprehensive diagnostics (audiological, speech therapy, psychological), an individualized rehabilitation plan, and a differentiated approach for users of hearing aids and cochlear implants. Educational modules for parents have been developed: psychological education, training in device handling, communication strategies, parental coaching, psychological support, social navigation, monitoring, and supervision. Innovative components include theater therapy and vocal lessons, which contribute to the development of prosody and strengthen parent-child relationships. The program is implemented by a multidisciplinary team (audiologist, ENT physician, speech-language pathologist, psychologist, social worker, coordinator) in accordance with a calendar model (0-1 month, 1-6 months, 6-24 months, preschool and school stages). Distance learning formats are provided for families from remote areas. The regional program of the Ivanovo region represents an example of a comprehensive family-centered approach that integrates modern evidence-based rehabilitation methods. This experience can serve as a model for the development of similar programs in other regions. Further research will be aimed at quantitative evaluation of the effectiveness of the described modules. \u041d\u0430\u0440\u0443\u0448\u0435\u043d\u0438\u044f \u0441\u043b\u0443\u0445\u0430 \u0443

with acute decompensated heart failure.\nAbstract: Monitoring pulmonary congestion in chronic heart failure (HF) reduces decompensation and hospitalization, but conventional methods such as weight and symptom tracking are often unreliable. As fluid accumulation affects the lungs and vocal tract, subtle voice alterations may serve as a non-invasive signal for early detection of worsening HF. The Voice Analysis for Monitoring Patients with HF trial (VAMP-HF, NCT06566911) prospectively enrolled 104 patients hospitalized with acute decompensated HF (ADHF) across two academic centres in the USA and Germany. Daily voice recordings were collected from admission to discharge, with breathing features extracted from speech and acoustic features from sustained vowels. A machine-learning model was trained to classify recordings as admission-phase vs. discharge-phase using leave-one-patient-out. Patients with clinical deterioration, insufficient audio quality, or short length of stay were excluded. Seventy-nine patients were included in the final dataset. The model classified admission and discharge with an F 1-score of 0.83 (95% CI: 0.77-0.90; AUC = 0.90). In patients with higher audio volume (N = 54), performance reached 0.89 (95% CI: 0.82-0.94; AUC = 0.91). When applied to intermediate hospitalization days, model-predicted scores showed progressive increases from admission towards discharge. Performance remained robust irrespective of significant weight loss during hospitalization. In this pilot study, structured voice and breathing analysis discriminated hospitalization phase from admission through discharge in patients with ADHF. This non-invasive approach captured progressive changes during the hospital course and warrants further investigation with concurrent objective congestion markers to establish physiological specificity.\n\nID: 42394857\nTitle: Role of Nkx2.2 immunohistochemistry in distinguishing Ewing sarcoma from neuroendocrine neoplasms at different sites.\nAbstract: Ewing sarcoma is a high grade round cell sarcoma that exhibits considerable histomorphological overlap with other round cell tumors, especially neuroendocrine neoplasms. In the present study, we compared the immunohistochemical expression of Nkx2.2 in cases of Ewing's sarcoma, neuroendocrine neoplasms at different sites, and a small subset of other mesenchymal and nonmesenchymal tumors in order to assess its utility in their distinction. This descriptive retrospective study lasted for 14 months and investigated 60 cases, with 17 cases of Ewing sarcoma, 34 cases of neuroendocrine neoplasms and nine cases of other tumors. Hematoxylin and eosin and Nkx2.2 immunohistochemistry-stained slides of previously diagnosed cases were retrieved and reviewed. Nkx2.2 exhibited sensitivity of 88.2% and specificity of 53.4% in the diagnosis of Ewing's sarcoma. Nkx2.2 expression was also present in neuroendocrine neoplasms (especially those of gastrointestinal and pancreatic origins) with 52.9% sensitivity and 34.6% specificity. Other neuroendocrine neoplasms that were positive for Nkx2.2 included those of prostate, female genital tract, and larynx origins. Among other tumors, pleomorphic sarcoma and melanoma exhibited Nkx2.2 positivity. Most cases (83.3%, 5/6) of lung neuroendocrine neoplasms were negative for Nkx2.2. Nkx2.2 exhibited high sensitivity in diagnosing Ewing's sarcoma and certain neuroendocrine neoplasms (especially those of gastrointestinal and pancreatic origins), but its lower specificity and varied expression across other tumor types highlight the need for a cautious and context-specific approach when used in clinical practice. \u062a\u064f\u0639\u062f \u0633\u0627\u0631\u0643\u0648\u0645\u0627

motion and audiovisual coherence framework.\nAbstract: Teleconsultations are exposed to digital impersonation and synthetic media attacks that can alter identity, articulation, or consent evidence, introducing emerging AI-enabled biosecurity risks to digitally mediated healthcare workflows. We evaluate an explainable integrity control based on motion dynamics and audiovisual temporal coherence, designed for conservative operation at extremely low false alarm rates with auditable evidence reporting to support governance and risk-based escalation. Our contribution is a reproducibility-oriented evaluation protocol and an evidence atlas of temporally grounded cues, together with a staged fusion that supports scalable prescreening and targeted verification under platform-style degradations characteristic of real-world dissemination chains. Building on prior biomarker-oriented analyses of physiological and structural cues for synthetic media detection, this work advances toward a calibrated, deployment-oriented integrity control architecture optimized for operational screening in telemedicine workflows. We use the DeepFake RealWorld (DFRW) dataset with 46,371 clips (229.28\u00a0h), combining 4,186 Open-Source Intelligence (OSINT) samples and 42,185 controlled, systematically degraded variants emulating recompression, resizing, filtering, and recapture. On the held-out binary-labeled test split, descriptor fusion reaches an AUC of 0.91 and achieves a true positive rate (TPR) of 18.5% (95% CI 16.2-20.8) at a false positive rate (FPR) of 0.1%, compared with 6.2% (95% CI 4.8-7.6) for an Xception baseline fine-tuned on the DFRW dataset. Microbenchmarked latencies motivate a two-stage deployment with explicit abstention and a structured integrity report aligned with healthcare governance and post-incident auditing requirements. This study evaluates telemedicine-oriented integrity controls using a benchmark dataset and does not claim demographic or clinical subgroup generalizability. Before deployment in clinical workflows, the proposed approach requires broader validation across age groups, ethnic backgrounds, speech characteristics, capture conditions, and medical conditions that may affect facial motion, articulation, or voice production. Prospective subgroup validation and governance-oriented assessment should therefore be treated as necessary directions for future work.\n\nID: 42390167\nTitle: Depression markers in speech: An approach based on tract variables dynamics.\nAbstract: This study identifies new depression biomarkers based on the dynamical properties of tract variables, which represent geometric features describing the configuration of the speech articulators. A key advantage of this approach lies in its ability to quantify aspects of the articulatory process that have not been previously explored in the context of depression, namely, predictability, complexity, and randomness. These properties are respectively characterised using the Largest Lyapunov Exponent, the Correlation Dimension, and the Sample Entropy. Thorough experiments were conducted on the Androids Corpus, a publicly available dataset comprising 64 speakers diagnosed with depression by clinicians and 54 control speakers with no reported history of mental health conditions. The results indicate that the proposed biomarkers effectively discriminate between the depressed and control speakers, as evidenced by the high Cliff's delta values across both read and spontaneous speech.\n\nID: 42385684\nTitle: [Ultrasonography of the ventral cervical soft tissues in dogs - an underestimated diagnostic method in the evaluation of mass lesions].\nAbstract: Ventral cervical masses present a diagnostic challenge in dogs, as patient history and clinical examination alone frequently do not reveal their origin or cause. Ultrasonography is considered the imaging modality of choice. It allows detailed evaluation of anatomical structures without radiation exposure and usually without the need for anesthesia. Proper patient positioning (dorsal recumbency with extended head), clipping and the use of a high-frequency linear transducer are essential. A systematic approach based on anatomical landmarks - starting at the larynx and trachea, proceeding to the salivary glands and lymph nodes to blood vessels - is crucial for accurate assessment. A thorough understanding of the physiologic sonographic anatomy of the neck structures is mandatory to identify pathological changes. Key evaluation criteria for cervical masses include location, size, extent, margins, echogenicity, echotexture and vascularity. For example, anechoic lesions typically indicate fluid-filled structures, while enlarged hypoechoic lymph nodes may suggest inflammatory or neoplastic processes. Abscesses usually appear as cavities with thick walls, and foreign bodies are clearly visible when they exhibit a smooth, linear, echogenic, sound-attenuating surface and are surrounded by fluid. Thyroid tumors are frequently large and heterogeneous, sometimes with mineralization. The differentiation between benign and malignant lesions, however, is not possible based on ultrasound alone. A major advantage of ultrasonography is the ability to guide interventions. Fine-needle aspiration or biopsy enables cytological or histopathological diagnosis. Additionally, foreign bodies can ideally be removed with minimally invasive procedures under ultrasound guidance. Umfangsvermehrungen im ventralen Halsbereich des Hundes stellen diagnostisch eine Herausforderung dar, da Ursprung und Ursache nach Erhebung der Vorgeschichte und der klinischen Untersuchung oft unklar bleiben. Die Sonografie erweist sich als initiale bildgebende Methode der Wahl. Sie erm\u00f6glicht eine detaillierte Darstellung von Strukturen ohne Strahlenbelastung und meist ohne Narkose. Voraussetzung ist die korrekte Lagerung des Patienten in R\u00fcckenlage mit gestrecktem Kopf, Scheren sowie die Verwendung eines hochfrequenten Linearschallkopfes. Eine systematische Untersuchung anhand anatomischer Leitstrukturen \u2013 beginnend beim Kehlkopf \u00fcber Trachea, Speicheldr\u00fcsen und Lymphknoten bis hin zu Blutgef\u00e4\u00dfen \u2013 ist entscheidend f\u00fcr eine sichere Orientierung.Kenntnis der normalen Sonoanatomie der Halsorgane ist Voraussetzung, um pathologische Ver\u00e4nderungen identifizieren zu k\u00f6nnen. Die Beurteilungskriterien bei Umfangsvermehrungen sind Lokalisation, Gr\u00f6\u00dfe, Ausdehnung, Abgrenzbarkeit, Echogenit\u00e4t, Echotextur und Durchblutung. So weisen beispielsweise anechogene L\u00e4sionen meist auf Fl\u00fcssigkeit hin, w\u00e4hrend hypoechogene, vergr\u00f6\u00dferte Lymphknoten entz\u00fcndlich oder neoplastisch ver\u00e4ndert sein k\u00f6nnen. Ein Abszess besteht typischerweise aus einer Kavit\u00e4t mit dicker Wand, Fremdk\u00f6rper sind gut erkennbar, wenn sie eine glatte, lineare, echoreiche, schallmindernde Oberfl\u00e4che aufweisen und von Fl\u00fcssigkeit umgeben sind. Schilddr\u00fcsentumore sind h\u00e4ufig gro\u00df, heterogen und teils mineralisiert; eine sichere Unterscheidung zwischen benignen und malignen Prozessen ist in der Regel nicht m\u00f6glich.Ein wesentlicher Vorteil der Sonografie ist die M\u00f6glichkeit ultraschallgest\u00fctzter Interventionen. Feinnadelaspiration oder Biopsie erlauben eine weiterf\u00fchrende zytologische bzw. histopathologische Diagnostik. Zudem k\u00f6nnen Fremdk\u00f6rper im Idealfall minimalinvasiv unter Ultraschallkontrolle entfernt werden.\n\nID: 42384108\nTitle: Immune checkpoint inhibitor-induced myasthenia gravis and myocarditis: a fatal immune-related adverse event.\nAbstract: Checkpoint inhibitors, a class of immunotherapeutic agents, have transformed the oncology landscape by targeting immune checkpoints - regulatory pathways that modulate immune cell activity. By inhibiting proteins such as programmed cell death 1 (PD-1), programmed cell death ligand 1 (PD-L1), and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), these agents enhance the immune response against cancer cells. However, their efficacy comes at the cost of a range of immune-related adverse events (irAEs), including autoimmune reactions such as colitis, hepatitis, and endocrinopathies, which can range in severity from mild to life-threatening. We present the case of a 76-year-old man with cholangiocarcinoma on durvalumab, a PD-L1 inhibitor, who presented to the emergency department with shortness of breath, cough, and weakness. Workup led to the diagnosis of immune-related myasthenia gravis and a non-ST-elevation myocardial infarction (NSTEMI), the latter believed to be secondary to durvalumab-induced myocarditis. Initial treatment with intravenous immunoglobulin (IVIG) produced brief, partial symptomatic improvement but failed to resolve respiratory weakness or other bulbar manifestations. His condition deteriorated rapidly, progressing to respiratory failure within weeks of onset. Given the refractory nature of his disease course, he was subsequently treated with a repeat dose of IVIG and prednisone, then transferred to an outside facility for plasma exchange. Despite these interventions, the patient ultimately succumbed to his illness. This case highlights the rare but potentially fatal concurrent occurrence of immune-related myasthenia gravis and myocarditis as irAEs in a patient receiving durvalumab for cholangiocarcinoma. While checkpoint inhibitors have revolutionized outcomes across many solid tumor malignancies, this case underscores the diagnostic and management challenges posed by severe, refractory irAEs, and the importance of early recognition and aggressive treatment in this patient population.\n\nID: 42381876\nTitle: From womb to words: the sex-specific interplay of fetal sex hormones and maternal mood on infant language development.\nAbstract: Language development is influenced by biological and environmental factors, including infant hormonal status and maternal mental health. Previous research on the role of infant sex hormones in language development focused on estradiol and testosterone, yet first evidence indicates that dehydroepiandrosterone (DHEA), the dominant fetal steroid hormone, may be a more sensitive biomarker for language development by shaping the organization of the developing brain. Concerning infants' language-learning environment, maternal well-being is a key factor, with maternal depressed mood postpartum, even at subclinical levels, negatively affecting language development, as depressed mothers engage less with their children and use less infant-directed speech. The present study examined the interplay of fetal DHEA levels and maternal mood at eight weeks postpartum on receptive language abilities at 12 months in boys and girls. Fetal DHEA levels were extracted from hair samples collected two weeks after birth (n\u00a0=\u00a058; 28 girls), allowing fetal hormone milieu quantification in the third trimester. Maternal mood in the subclinical depression range was assessed using the Edinburgh Postnatal Depression Scale. Children's receptive language abilities were assessed using the German version of the Bayley Scales of Infant and Toddler Development. Stepwise multiple linear regression analysis revealed fetal DHEA to predict language development in boys, with the effect depending on maternal mood. Only when mothers experienced better mood postpartum were higher DHEA levels related to lower language ability. By contrast, in girls, only maternal mood significantly contributed to language ability, with better mood relating to higher language outcome. Our findings suggest that the effect of infant sex hormones on language development follows sex-specific patterns and appears to be modulated by the learning environment. Moreover, our results emphasize the importance of mental support during the early stages of language development.\n\nID: 42379964\nTitle: \"I Go but I Don't Participate\": A Scoping Review With Thematic Synthesis of the Experiences of Voice Disorders in Adulthood.\nAbstract: Voice disorders affect nearly one in three people during their lifetime and are associated with significant reductions in quality of life. Despite this, limited research has explored the experiences of adults living with voice disorders. This review synthesizes patient-reported experiences and impacts of voice disorders in adulthood. Six databases (PubMed, CINAHL, Web of Science, Embase, Cochrane, and Scopus) were systematically searched, and studies were screened using an established scoping review framework. The included studies were analyzed following recognized principles of qualitative meta-synthesis. From 3525 studies identified, six met study inclusion criteria and underwent thematic synthesis. Five overarching themes emerged: 1) My voice doesn't sound or feel like it used to; 2) My voice disorder has diminished my emotional well-being and self-confidence; 3) My voice disorder impacts my life participation; 4) Stigma hurts, support helps; 5) Living with my voice disorder means learning to adapt. Recurring themes surrounding psychosocial well-being and life participation restriction highlight the need for clinicians to develop counseling skills and knowledge of when and how to refer for additional support. Clinicians are urged to use a more holistic approach to voice assessment and treatment, acknowledging that the impacts of voice disorders often extend well beyond the larynx.\n\nID: 42379748\nTitle: Impact of Intravenous Immunoglobulin on Neuroinflammation Markers in Patients With Electrical Status Epilepticus During Slow Sleep.\nAbstract: Electrical status epilepticus during slow sleep (ESES) is a rare syndrome that often presents with refractory seizures and cognitive impairment. Immune modulatory drugs may show higher efficacy than anti-seizure drugs (ASD) in ESES. Our study aimed to determine the immune-modulatory treatment-responsive subgroups through assessment of neuroinflammatory mediators. The study included thirty-five consecutively diagnosed patients with treatment-resistant ESES, all under ASD treatment and the control group comprised 25 individuals diagnosed with primary headache disorders. Serum, peripheral blood and cerebrospinal fluid (CSF) samples were collected before commencement and after the 12-month follow-up of monthly intravenous immunoglobulin (IVIg)+ASD regimen. Serum and/or CSF levels of YKL-40, CXCL13, HMGB1, GFAP and NFL and NLRP3 and IL1\u03b2 gene expression levels in peripheral blood mononuclear cells (PBMC) were measured using ELISA and real time quantitative PCR, respectively. Seizures and ESES activity ceased in 20 (57.1%) patients with ESES. Under IVIg+ASD, CSF levels of YKL-40, CXCL13, HMGB1 and GFAP and serum levels of YKL-40 and HMGB1 were significantly reduced, whereas serum CXCL13, CSF NFL, PBMC NLRP3 and IL1\u03b2 levels remained comparable among groups. Enhanced baseline CSF CXCL13, CSF HMGB1 and PBMC IL1\u03b2 levels were associated with treatment resistance (n=15, 42.9%) in ESES. Levels of neuroinflammation markers were comparable among etiology subgroups (rolandic epilepsy, genetic abnormalities, cerebral palsy). IVIg treatment dampens the neuroinflammatory response and thus immune-modulatory treatment in combination with ASD may contribute to the improvement of ESES symptoms. CXCL13, HMGB1 and IL-1\u03b2 may serve as markers of immune-modulatory treatment response in ESES.\n\nID: 42378353\nTitle: [Ortner syndrome as a cause of sudden dysphonia, a little-known etiology].\nAbstract: A 77-year-old woman was admitted with symptoms of heart failure and sudden dysphonia. Imaging tests revealed a pericardial effusion and the existence of severe cardiomegaly at the expense of an aneurysmal left atrium. Pericardiocentesis was performed, with improvement in the clinical picture of heart failure, although residual dysphonia persisted upon discharge. Ortner syndrome or cardiovocal syndrome consists of paralysis of the left recurrent laryngeal nerve caused by a cardiovascular condition, usually and originally described by left atrial dilation in relation to rheumatic mitral valve disease. Early diagnosis can be useful to initiate immediate treatment and restore vocal cord function. When assessing possible causes of dysphonia, it is important to take into account the cardiac etiology, since despite the fact that this syndrome has a low prevalence, it is important to take it into account since its treatment requires multidisciplinary management.

A la hora de valorar posibles causas de disfon\u00eda, es importante tomar en cuenta la etiolog\u00eda cardiaca ya que a pesar de que este s\u00edndrome tiene baja prevalencia, es importante tomarlo en cuenta ya que su tratamiento requiere un manejo multidisciplinario.\n\nID: 42377572\nTitle: Cerebellar pathway diffusion MRI measures are linked to core autism symptoms in early adolescents aged 9 to 11 years.\nAbstract: In this preregistered study, we used diffusion MRI (dMRI) to characterize the tissue properties of cerebellar pathways in 9-11-year-old early adolescents from the Adolescent Brain Cognitive Development (ABCD) Study. We examined fractional anisotropy (FA), mean diffusivity (MD), and number of streamlines (NoS) across five cerebellar pathways-the inferior, middle, and superior cerebellar peduncles, the input and Purkinje fibers, and the parallel fibers-in adolescents with (n\u2009=\u2009135) and without (n\u2009=\u20097276) a parent-reported ASD diagnosis. We further tested whether cerebellar dMRI measures differentially related to core ASD symptom domains of social communication and interaction (SCI) and restricted and repetitive behaviors (RRB). Group comparisons revealed significant differences in cerebellar NoS (Pillai's trace p\u2009=\u2009.033), driven by greater NoS of the superior cerebellar peduncle in early adolescents with ASD; FA and MD showed no significant group effects. Cerebellar pathway dMRI measures exhibited significant interactions with diagnosis in relation to ASD symptom severity. The superior cerebellar peduncle demonstrated the strongest diagnosis-dependent interaction effects, with the NoS showing markedly stronger associations with both social communication (\u0394\u03b2\u2009=\u20090.14, p\u2009=\u2009.0019) and restricted and repetitive behaviors (\u0394\u03b2\u2009=\u20090.21, p\u2009<\u2009.0001) in children with ASD. These findings highlight the superior cerebellar peduncle as a key pathway of structural variability and highlight dMRI measures of the cerebellar pathways as meaningful correlates of ASD symptoms in early adolescence.\n\nID: 42366318\nTitle: The shaky voice of aging localized to the larynx: dissociation of frequency and amplitude tremor.\nAbstract: Aging is associated with structural and functional changes of the vocal folds that may result in presbyphonia, often perceived as a weak or shaky voice. However, the quantitative characterization of underlying age-related vocal tremor across the adult lifespan remains limited. This cross-sectional study investigated the characteristics of vocal tremor across the adult lifespan using automated acoustic analysis. A total of 291 native speakers aged 18-94 years were recruited and underwent perceptual voice evaluation and acoustic analysis during sustained phonation of the vowel /a/. Vocal tremor was quantified using digital signal processing, focusing on the prominence of fundamental frequency tremor (PF0T) and the prominence of amplitude tremor (PAT). A moderate-to-strong positive correlation between age and PF0T was observed in both males and females, indicating increasing instability of fundamental frequency with advancing age. In contrast, PAT did not show a significant age-related increase after correction for multiple comparisons. Perceptual ratings of tremor demonstrated only weak correlations with age but were moderately associated with acoustic measures of tremor. Normative models revealed that physiological tremor in healthy aging remains well below pathological thresholds reported in neurological disorders. These findings indicate that age-related vocal tremor is characterized predominantly by increasing instability of fundamental frequency rather than amplitude modulation, localizing the dominant age effect to laryngeal control of vocal fold tension rather than to respiratory drive. Automated acoustic analysis provides a sensitive and objective method for detecting subtle age-related vocal changes and may support future biomarker development for distinguishing physiological from pathological vocal tremor.\n\nID: 42362553\nTitle: Smartphone-derived digital motor measures to monitor progression in idiopathic REM sleep behavior disorder.\nAbstract: Sensitive and scalable biomarkers are critical for tracking progression during the prodromal phase of Parkinson's disease, particularly in idiopathic REM sleep behavior disorder (iRBD). We evaluated the Roche PD Mobile Application version 2, a smartphone-based platform, in 51 individuals with polysomnography-confirmed iRBD, 89 patients with early Parkinson's disease, and 22 healthy controls over 12 months. Participants completed daily active tasks generating validated digital summary measures. Adherence was high (73%). Baseline digital bradykinesia scores discriminated between groups (p\u2009<\u20090.001) and were higher in phenoconverters versus non-converters (p\u2009=\u20090.003; Cohen's d\u2009=\u20091.10). Over 50 weeks, bradykinesia (Cohen's d\u2009=\u20090.50) and speech (Cohen's d\u2009=\u20090.79) scores worsened significantly. Sample size modeling showed that digital bradykinesia required 132 participants per arm to detect a 50% treatment effect, fewer than the best-performing clinical measure. These findings support digital bradykinesia as a sensitive endpoint for prodromal Parkinson's disease trials.\n\nID: 42361702\nTitle: Spectral super-resolution for Parkinson's voice via representation-level methods under mixed-reality acquisition.\nAbstract: Voice is a practical remote biomarker for Parkinson's disease (PD), but real-world capture often yields low-resolution time-frequency inputs that under-resolve diagnostically salient microstructure. In this controlled empirical comparison, we test whether spectrogram super-resolution (SR) at the feature level performed inside the model rather than via waveform resynthesis improves PD vs. healthy control (HC) discrimination under realistic constraints. Speech was recorded with a Microsoft HoloLens 2 using a standardized mixed-reality (MR) protocol from 161 speakers (75 PD/86 HC) across five tasks: Task 1 image description, Task 2 question answering, Task 3 story repetition, Task 4 sustained vowels, and Task 5 word repetition (DDK). Raw audio was exported as 48 kHz, 16-bit PCM, downmixed to mono, amplitude-normalized, conservatively trimmed for leading/trailing silence, and resampled to 16 kHz. Log-mel spectrograms (80 bins) were fed to practical ImageNet-pretrained backbones (ConvNeXt-Tiny, ResNet-50, EfficientNetV2-S). We compared six super-resolution (SR) strategies: identity, nearest (deterministic), bilinear SR, kernel/CARAFE-like SR, LIIF-like SR, and a frozen universal feature SR module (AnyUp) that upsamples intermediate feature maps. Evaluation used 5-fold, speaker-disjoint cross-validation with AUROC (AUC) and accuracy (ACC). AnyUp was the most consistent top performer, ranking first in 11/15 backbone-task cells. Gains were largest on tasks dominated by fine spectro-temporal cues: for ConvNeXt-Tiny, AnyUp vs. identity improved sustained vowels (Task 4) by \u0394AUC 0.030/\u0394ACC 0.070 and DDK (Task 5) by \u0394AUC 0.054/\u0394ACC 0.045. Macro-averaged over tasks, AnyUp outperformed identity by +0.025 AUC/+0.045 ACC (ConvNeXt-Tiny), +0.015/+0.027 (ResNet-50), and +0.052/+0.048 (EfficientNetV2-S). Representative best-in-class results include AUC/ACC of 0.899/0.886 (Task 4) and 0.927/0.897 (Task 5) for ConvNeXt-Tiny+AnyUp, and 0.940/0.903 (Task 5) for ResNet-50+AnyUp. Densifying spectrogram representations with a frozen, universal feature super-resolution module yields consistent, compute-efficient improvements in PD voice classification under MR-standardized acquisition, with the largest benefits on sustained vowels and DDK. The contribution is empirical rather than architectural: we compare practical representation-level SR choices rather than introduce a new SR module. Feature-level super-resolution is therefore a pragmatic alternative or complement to bandwidth extension when waveform synthesis is unnecessary. At a macro level, the observed accuracy gains (e.g., +0.045 for ConvNeXt-Tiny) suggest that representation-level SR may be operationally useful in low-resolution clinical-audio settings.\n\nID: 42361332\nTitle: Patient-Reported Symptom Burden in Individuals With Parkinson Disease.\nAbstract: To better understand Parkinson disease (PD) burden and advance the clinical management of patients, it is important to ascertain the most significant symptoms directly from individuals with PD. This research used patient-reported data to identify the most prevalent and impactful symptoms experienced by individuals with PD and determine the demographic and clinical characteristics that are associated with higher symptomatic burden. We conducted semistructured qualitative interviews of 20 individuals with self-reported PD, obtaining 2,978 quotes regarding potential symptoms of importance. Findings from these interviews informed the development of a cross-sectional survey study designed to asess the impact of these symptoms in a larger cohort. Four-hundred four participants with self-reported PD participated in the survey study, providing the prevalence and relative importance (0-4 scale) of 301 symptoms representing 14 symptomatic themes. We subsequently performed subgroup analysis to identify demographic and clinical characteristics that were associated with a higher prevalence of symptomatic burden in PD. The most prevalent symptomatic themes identified by participants were sleep disturbances and daytime sleepiness (87.0%) and fatigue (84.7%). The symptomatic themes with the greatest impact (0-4) on participants' lives were fatigue (1.34) and sleep disturbances and daytime sleepiness (1.29). A higher prevalence of disease burden across all symptomatic themes was most strongly associated with speech impairment, gait freezing, and a duration of tremor greater than 5 years. The impact of PD on the lives of those living with this disease is multisystemic, reaching beyond the cardinal motor symptoms. Fatigue, sleep disturbances, and daytime sleepiness are highly prevalent and important to this population.\n\nID: 42423253\nTitle: Laryngeal Cryotherapy for Neurogenic Cough: Safety, Feasibility, and Prospective Outcomes.\nAbstract: Despite the prevalence of neurogenic chronic cough (NCC), treatment options remain limited. This study investigates selective laryngeal cryotherapy (SLC) as a potential sensory neurolytic therapy. The primary objective was to explore the feasibility and safety of SLC, while the secondary objectives assessed efficacy in the reduction of laryngeal hypersensation and cough symptoms. Patients with refractory NCC were prospectively recruited. Patients underwent laryngeal laser sensory testing (LST), immediately followed by awake SLC treatment. Cough measures including the cough severity index (CSI) and urge to cough visual analog scale (UTC-VAS) were collected at baseline and regular intervals. At 1-month postprocedure, additional LST was performed. Safety, tolerability, and adverse events were recorded. Thirty patients with NCC were enrolled. All patients successfully completed awake SLC. There were no serious adverse events or unanticipated adverse device effects. 21% of patients experienced at least one treatment-emergent adverse event, all of which self-resolved within 2\u2009days. Post-SLC patients had a higher mean laser power threshold, 7.5\u2009W (SD 2.42) to trigger a cough response compared to their baseline threshold of 2.8\u2009W (SD 2.76) (p\u2009<\u20090.001). By 6 months, patients demonstrated sustained improvement compared to their baseline, with a reduction in CSI of -8.25 (95% CI 11.60, -4.91) (p\u2009<\u20090.001) and UTC-VAS -18.07 (95% CI -29.71, -6.43) (p\u2009=\u20090.003). The data suggest that awake laryngeal cryotherapy is feasible, tolerable, and safe. SLC reduced laryngeal hypersensitivity, and while it is a promising treatment option for neurogenic cough, further research is required to confirm its long-term effectiveness.\n\nID: 42422859\nTitle: xHD-Vox, an Automated Speech Model for Estimating Motor and Cognitive Scores in Huntington Disease: Development and Longitudinal Validation.\nAbstract: Huntington disease (HD) is a rare genetic neurodegenerative disease that causes progressive motor, cognitive, and psychiatric symptoms over decades after onset. Clinical care is typically provided in specialized centers with only annual clinical assessments, highlighting the need for more frequent and cost-effective monitoring. This study aimed to develop and validate xHD-Vox, a fully automated, interpretable, speech-based model for predicting the composite Unified Huntington Disease Rating Scale (cUHDRS) and its cognitive, motor, and functional components. We included 181 HD gene carriers (341 annual visits) from three French prospective cohorts: BIO-HD (NCT01412125), REPAIR-HD (NCT03119246), and MIG-HD (NCT00190450). Participants had \u226540 cytosine-adenine-guanine (CAG) repeats, available cUHDRS scores, and audio recordings of forward and backward counting (1-20). For model development and feature selection, we used a speech pathologist-annotated subset (145 visits and 90 participants). Selected speech features were then automated using Whisper, an open-source speech recognition tool. The final linear regression model, xHD-Vox, was calibrated on the training set of 269 visits (157 participants, and annotated subset included). Performance was evaluated on an independent longitudinal test set (24 participants, with 3 annual visits each) using mean absolute error, explained variance (R \u00b2), and intraclass correlation coefficient. Longitudinal decline was assessed with 2-way repeated-measures ANOVAs. Predicted 1-year and 2-year changes were compared with clinician-assessed 95% CIs. Feature selection identified four key predictors: standardized CAG-age-product score, CAG repeat length, rate of numbers pronounced per second, and the SD of that rate. On the test set, xHD-Vox achieved a mean absolute error of 2.1 for cUHDRS and explained 57% of its variance, compared with 38% when using only demographic features. Longitudinal analyses using repeated-measures ANOVAs with post hoc Tukey tests confirmed a significant decline over the 2-year follow-up for both clinician-assessed measures and xHD-Vox predictions. At the group level, the mean 1-year and 2-year changes predicted by xHD-Vox were consistent with clinically measured changes, falling within the corresponding 95% CIs. We developed xHD-Vox, an interpretable and automated model that predicts clinical scores in HD using a short speech task. Predicted scores were consistent with clinician-assessed scores, supporting its potential use in mobile apps for remote monitoring. This approach could facilitate scalable, real-time tracking of disease progression, especially in underserved regions, and enable personalized and responsive clinical care.\n\nID: 42422787\nTitle: Efficacy of superiorly based nasolabial flap in post-mucor infrastructure maxillectomy defects.\nAbstract: Reconstruction of post-mucor oral cavity defects (ranging from simple alveolectomy defects to complete maxillectomy defects) will improve the function, esthetics, and general health of an individual. Various surgical and prosthetic options are available for the successful reconstruction of the defects. The nasolabial flap has versatile role in the reconstruction of oral cavity defects because of its proximity to the defect area, optimal esthetic results, and less surgical morbidity unlike distant flaps. In this study, we assessed the efficiency of the nasolabial flap in reconstruction of post-mucor infrastructure maxillectomy defects in 42 individuals by comparing the pre-surgical and post-surgical abilities to speak and swallow. Patients with post-mucor infrastructure maxillectomy defects were involved in this prospective study. Fifty-one patients who met the inclusion criteria were selected. All the study parameters (swallowing ability, hypernasality, speech intelligibility, and subjective satisfaction of an individual) were assessed preoperatively. Reconstruction of the defect was done with a superiorly based nasolabial flap. Nine patients were lost to follow up, and 42 patients were followed up for six months to evaluate the study parameters. Pre-surgical and post-surgical statistical data analysis shows that there is a significant improvement in the functional outcomes of an individual. 76% of the patients showed no signs of nasal regurgitation, dribbling of saliva, or coughing upon swallowing after reconstruction of the defect with nasolabial flap. Significant improvement in speech after the closure of maxillary defect was observed as 93% of patients had socially acceptable speech and 64.5% had normal intelligible speech postoperatively. Upon subjective satisfaction assessment, 64% of the patients were satisfied with the treatment procedure. Closure of oro-antral communication and creation of a seal between oral and nasal cavities using the nasolabial flap leads to improvement in the function of an individual in terms of speech intelligibility and swallowing ability. The nasolabial flap can be considered as an optimal option for managing post-mucor infrastructure maxillectomy defects by restoring functional and psychosocial well-being of a person.\n\nID: 42421640\nTitle: Digital Interventions for First-Time Hearing Aid Users: A Systematic Review and Meta-Analysis of Efficacy and Effectiveness.\nAbstract: Digital interventions are increasingly used to support hearing aid users; however, evidence for first-time hearing aid users remains unclear. This systematic review and meta-analysis evaluated the efficacy and effectiveness of digital interventions to improve outcomes for first-time hearing aid users. The protocol was pre-registered (PROSPERO; CRD420251125785) and conducted in accordance with PRISMA 2020. PubMed, Scopus, and Web of Science were searched (January 2026). Eligible studies included randomized controlled trials, controlled clinical trials, and quasi-experimental studies evaluating internet-, app-, or web-based interventions. Outcomes were grouped into six domains: hearing aid use, benefit and satisfaction, hearing and communication, knowledge, skills and self-management, speech-in-noise performance, and psychosocial and emotional adjustment. Risk of bias was assessed using RoB 2 and ROBINS-I, and certainty of evidence using GRADE. Random-effects meta-analyses were conducted where \u22653 randomized trials reported comparable outcomes. Eleven publications (nine trials) were included. Most interventions focused on education, self-management, and counseling, with few targeting perceptual training. The most consistent improvements were observed in knowledge, skills and self-management (moderate-certainty). Evidence for hearing aid use, benefit and satisfaction, hearing and communication, and psychosocial and emotional adjustment was limited and inconsistent (low-certainty), while speech-in-noise evidence was of very low certainty. Meta-analyses of hearing aid use and IOI-HA outcomes showed no significant pooled effects. Digital interventions show the most consistent evidence for improving knowledge, skills, and self-management. Evidence for other outcomes remains limited and inconsistent. Clinicians may consider digital educational programs complementing standard care. Future research should prioritize larger, pre-registered trials with broader interventions and standardized outcomes.\n\nID: 42421343\nTitle: Interaction Between Head Movement Behavior and Simulated Spatial Filtering: Comparing Free Conversation and Speech Tests in Virtual Reality.\nAbstract: The benefit provided by hearing devices often differs between laboratory evaluations and real-world conditions, due to low signal-to-noise ratio (SNR) in adaptive speech tests and differences in head movement behavior between laboratory evaluations and real conversations. This study aimed to investigate whether SNR improvement provided by a spatial filter can be measured during free conversation in virtual reality (VR) and to compare this SNR improvement with the benefit measured using a speech test with two spatially separated talkers in the same VR. Two experimental conditions were tested in 11 normal-hearing participants. Condition 1 involved free conversations between a participant and two confederates represented by avatars, and Condition 2 utilized an adaptive speech test with two speakers, presented by the same avatars. Acoustic simulations were used to render speech signals, background noise and room acoustics. A spatial filter with two levels of selectivity was simulated in VR using the participant's actual dynamic head orientation. Acoustic measures of the benefit of the spatial filter were derived from these simulated signals. The benefit was higher when measured in free conversations than in the speech test. Additionally, participants were found to move their heads closer to active speakers during free conversation than during the speech test. Furthermore, SNR in free conversations was closer to SNRs typical of conversational environments. These findings suggest that the effectiveness of hearing devices can be evaluated through conversations in VR at more realistic SNRs. Consequently, this approach may improve the ecological validity of hearing aid research outcomes.\n\nID: 42421334\nTitle: Global disparities in hearing care services and infrastructure: findings from a 47-country international provider survey.\nAbstract: Access to audiological services and support for individuals with hearing loss varies widely across low- and middle- income countries (LMICs) and high-income countries (HICs). This study examines disparities in the availability of audiological services across World Bank income groups. An international cross-sectional survey was developed and distributed by the Global Otolaryngology Head and Neck Surgery Initiative. The survey evaluated the availability of audiology and support services across countries. Multiple responses from one country were combined into one entry. Statistical significance between groups was assessed using chi-squared tests.Study Sample: A total of 135 responses were received from 47 countries (30 LMICs and 17 HICs). Significant disparities were identified across most service categories. HICs reported greater availability of newborn hearing screening, diagnostic tests, paediatric and adult hearing assessments, vestibular services, and hearing technologies compared to LMICs. Advanced diagnostic tools and hearing devices such as cochlear implants were significantly more accessible in HICs. Substantial differences were observed in audiological and rehabilitative services across HICs and LMICs. Efforts to bridge significant gaps are essential for achieving equitable hearing health care worldwide.\n\nID: 42421165\nTitle: Adaptation and psychometric evaluation of the Croatian developmental coordination disorder questionnaire (DCDQ-HR).\nAbstract: Developmental coordination disorder is a condition characterized by impaired motor skills, which can have a significant impact on participation and quality of life. Evaluation and diagnosis using valid instruments is critical for ensuring timely and appropriate intervention. This study aimed to conduct a cross-cultural adaptation and examine the psychometric properties of a Croatian adaptation of the Developmental Coordination Disorder Questionnaire (DCDQ), a 15-item parent questionnaire designed to evaluate the impact of motor coordination difficulties on performance in everyday activities. Questionnaire adaptation was conducted according to guidelines for cross-cultural adaptation of measurement instruments. The Croatian adaptation of the questionnaire was completed by parents of 413 children (5-15\u2009years). Factor structure was examined using exploratory, following by confirmatory, factor analyses. Gender and age distributions were examined using inferential statistics. Internal consistency and item-total correlations were high. Inferential statistics revealed a statistically significant difference in overall scores for sex, but not age. Factor analysis revealed a 4-factor solution different from the 3-factor solution found for the original version of the questionnaire, in which items were grouped under the following 4 factors: ball coordination, fine motor/handwriting, control during movement, and general coordination. Other tests of validity indicated that items under each factor measure unique aspects of motor coordination while at the same time being logically related to one another. Results suggest that the Croatian adaptation of the DCDQ is a potentially useful instrument for understanding and evaluating the impact of motor coordination difficulties on daily activities. Further research is necessary to more clearly determine the scale's factor structure and to confirm age cutoffs for screening purposes.\n\nID: 42420022\nTitle: [Associations between central auditory processing function and attentional function in age-related hearing loss].\nAbstract: Objective: To investigate the relationships between peripheral auditory function, central auditory processing, and attentional function in individuals with age-related hearing loss (ARHL), thereby providing scientific evidence for the clinical assessment and intervention of ARHL. Methods: A total of 32 individuals with ARHL who were recruited from Peking Union Medical College Hospital between September 2020 and March 2024 were enrolled, including 12 males and 20 females, aged 60-73 years (mean age: 66.1 years). Additionally, 32 age-matched individuals with normal hearing were recruited as the control group, including 14 males and 18 females, aged 60-70 years (mean age: 65.4 years). Peripheral auditory function was assessed using pure-tone audiometry (PTA). Central auditory processing was evaluated using the speech-in-noise (SIN) test and the gaps-in-noise (GIN) test. Attentional function was assessed with the digit vigilance test (DVT). Statistical analyses were performed using SPSS 27.0 software. Results: Compared with the control group, individuals with ARHL exhibited significantly prolonged DVT reaction time (RT), indicating poorer performance on the attention task [ARHL group: (210.2\u00b143.1) s; control group: (189.3\u00b137.3) s; t=2.068, P=0.043]. In the ARHL group, SIN threshold was significantly positively correlated with DVT RT (pr=0.502, P=0.005). Among all participants, both SIN and GIN thresholds were significantly positively correlated with DVT RT (SIN: pr=0.691, P<0.001; GIN: pr=0.349, P=0.006), whereas the PTA threshold showed only a marginal correlation with DVT RT (pr=0.229, P=0.075). Multiple linear regression analysis revealed that the SIN threshold was the only auditory measure independently associated with DVT RT (\u03b2=9.673, 95%CI: 3.611-15.734, P=0.002). Conclusions: Individuals with ARHL demonstrate prolonged RT on attention-related tasks, suggesting a potential decline in attentional processing speed. The association between central auditory processing ability and attentional processing speed is substantially stronger than that between peripheral auditory function and attentional processing speed. These findings suggest that central auditory processing function may have potential value in the investigation and assessment of cognitive function in older adults. \u76ee\u7684\uff1a \u63a2\u8ba8\u5e74\u9f84\u76f8\u5173\u542c\u529b\u635f\u5931\uff08age-related hearing loss\uff0cARHL\uff09\u60a3\u8005\u5916\u5468\u542c\u89c9\u529f\u80fd\u53ca\u4e2d\u67a2\u542c\u89c9\u5904\u7406\u529f\u80fd\u4e0e\u6ce8\u610f\u529f\u80fd\u4e4b\u95f4\u7684\u5173\u7cfb\uff0c\u4e3aARHL\u7684\u4e34\u5e8a\u8bc4\u4f30\u53ca\u5e72\u9884\u63d0\u4f9b\u79d1\u5b66\u4f9d\u636e\u3002 \u65b9\u6cd5\uff1a \u7814\u7a76\u5bf9\u8c61\u4e3a2020\u5e749\u6708\u81f32024\u5e743\u6708\u5c31\u8bca\u4e8e\u5317\u4eac\u534f\u548c\u533b\u9662\u768432\u4f8bARHL\u60a3\u8005\uff0c\u5176\u4e2d\u753712\u4f8b\uff0c\u597320\u4f8b\uff0c\u5e74\u9f84\u8303\u56f460~73\u5c81\uff0c\u5e73\u5747\u5e74\u9f8466.1\u5c81\u3002\u53e6\u5916\u62db\u52df32\u540d\u542c\u529b\u6b63\u5e38\u4eba\u4f5c\u4e3a\u5bf9\u7167\u7ec4\uff0c\u5176\u4e2d\u753714\u4f8b\uff0c\u597318\u4f8b\uff0c\u5e74\u9f84\u8303\u56f460~70\u5c81\uff0c\u5e73\u5747\u5e74\u9f8465.4\u5c81\u3002\u53d7\u8bd5\u8005\u5916\u5468\u542c\u89c9\u529f\u80fd\u901a\u8fc7\u7eaf\u97f3\u6d4b\u542c\u8fdb\u884c\u8bc4\u4f30\uff0c\u4e2d\u67a2\u542c\u89c9\u5904\u7406\u529f\u80fd\u901a\u8fc7\u566a\u58f0\u4e0b\u8a00\u8bed\u8bc6\u522b\uff08speech-in-noise\uff0cSIN\uff09\u53ca\u566a\u58f0\u95f4\u9694\uff08gaps-in-noise\uff0cGIN\uff09\u6d4b\u8bd5\u52a0\u4ee5\u8bc4\u4f30\u3002\u901a\u8fc7\u6570\u5b57\u8b66\u9192\u6d4b\u8bd5\uff08digit vigilance test\uff0cDVT\uff09\u8bc4\u4f30\u53d7\u8bd5\u8005\u6ce8\u610f\u529f\u80fd\u3002\u91c7\u7528SPSS 27.0\u8f6f\u4ef6\u5b8c\u6210\u7edf\u8ba1\u5206\u6790\u3002 \u7ed3\u679c\uff1a \u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0cARHL\u60a3\u8005\u7684DVT\u53cd\u5e94\u65f6\u95f4\u663e\u8457\u5ef6\u957f\uff0c\u5dee\u5f02\u5177\u6709\u7edf\u8ba1\u5b66\u610f\u4e49\uff3bARHL\u7ec4\uff1a\uff08210.2\u00b143.1\uff09s\uff1b\u5bf9\u7167\u7ec4\uff1a\uff08189.3\u00b137.3\uff09s\uff1bt=2.068\uff0cP=0.043\uff3d\u3002SIN\u9608\u503c\u4e0eDVT\u53cd\u5e94\u65f6\u95f4\u5728ARHL\u7ec4\u4e2d\u5448\u663e\u8457\u6b63\u76f8\u5173\uff08pr=0.502\uff0cP=0.005\uff09\u3002\u5728\u6240\u6709\u53d7\u8bd5\u8005\u4e2d\uff0cSIN\u9608\u503c\u548cGIN\u9608\u503c\u5747\u4e0eDVT\u53cd\u5e94\u65f6\u95f4\u663e\u8457\u76f8\u5173\uff08SIN\uff1apr=0.691\uff0cP<0.001\uff1bGIN\uff1apr=0.349\uff0cP=0.006\uff09\uff0c\u800c\u7eaf\u97f3\u5e73\u5747\u542c\u9608\u4e0eDVT\u53cd\u5e94\u65f6\u95f4\u4ec5\u5448\u8fb9\u7f18\u76f8\u5173\uff08pr=0.229\uff0cP=0.075\uff09\u3002\u591a\u5143\u7ebf\u6027\u56de\u5f52\u5206\u6790\u7ed3\u679c\u663e\u793a\uff0cSIN\u9608\u503c\u662f\u552f\u4e00\u4e0eDVT\u53cd\u5e94\u65f6\u95f4\u72ec\u7acb\u76f8\u5173\u7684\u542c\u89c9\u8bc4\u4f30\u6307\u6807\uff08\u03b2=9.673\uff0c95%CI=3.611~15.734\uff0cP=0.002\uff09\u3002 \u7ed3\u8bba\uff1a ARHL\u60a3\u8005\u6ce8\u610f\u76f8\u5173\u4efb\u52a1\u53cd\u5e94\u65f6\u95f4\u5ef6\u957f\uff0c\u63d0\u793a\u6ce8\u610f\u52a0\u5de5\u901f\u5ea6\u53ef\u80fd\u53d7\u635f\u3002\u8001\u5e74\u4eba\u4e2d\u67a2\u542c\u89c9\u5904\u7406\u80fd\u529b\u4e0e\u6ce8\u610f\u52a0\u5de5\u901f\u5ea6\u7684\u76f8\u5173\u6027\u663e\u8457\u5f3a\u4e8e\u5916\u5468\u542c\u89c9\u80fd\u529b\u3002\u4e2d\u67a2\u542c\u89c9\u5904\u7406\u529f\u80fd\u5728\u8001\u5e74\u4eba\u8ba4\u77e5\u529f\u80fd\u7814\u7a76\u53ca\u8bc4\u4f30\u4e2d\u53ef\u80fd\u5177\u6709\u4e00\u5b9a\u7684\u6f5c\u5728\u4ef7\u503c\u3002.\n\nID: 42418971\nTitle: Machine learning-based detection of Parkinson's disease from facial expressions, hand movements, speech, and gait with general-purpose equipment: a systematic review.\nAbstract: Parkinson's disease (PD) diagnosis remains largely subjective, relying on clinical symptom assessment. The convergence of machine learning (ML) with low-cost, widely available digital devices creates new opportunities for objective, scalable, and accessible PD screening and monitoring. This systematic literature review aims to examine ML approaches for PD detection, early diagnosis, severity assessment, and stage classification using four key data modalities: facial expressions, hand movements, speech and voice, and gait employing general-purpose, low-cost equipment. A systematic literature review of 133 papers published between January 2020 and June 2025 was conducted following PRISMA 2020 guidelines. Data were extracted on feature extraction techniques, assessment protocols, computational frameworks, classifier architectures, performance metrics, and participant cohorts for each modality and for multimodal fusion studies. The quality of multimodal fusion studies was evaluated using the IJMEDI checklist. Cross-modality comparison for PD vs. healthy control classification indicated a promising trend for speech and voice modality. Binary classification was the most common ML task (74.5% of studies). Support Vector Machines (SVM) and Random Forests (RF) were the predominant classifiers. While multimodal data fusion demonstrated a promising trend toward improved performance (observed in 75% of studies), this finding requires cautious interpretation due to the limited statistical validation in the source literature. This review synthesizes the current landscape of ML-based PD assessment using accessible hardware. It demonstrates the technical viability and performance advantages of multimodal systems while providing a detailed compendium of methodologies for signal processing, feature engineering, and model selection. These findings support the development of practical, cost-effective tools for remote PD screening and monitoring.\n\nID: 42418303\nTitle: Diagnostic Agreement and 1-Year Outcomes in Functional Neurological Disorder Following Neuroscience-Informed Assessment, Education, and Counseling: A Retrospective Cohort Study.\nAbstract: We sought to explore outcomes at 1\u00a0year in functional neurological disorder (FND) following a neuroscience-informed education and counseling assessment. Patients with FND were assessed at a quaternary neuropsychiatry clinic in Toronto, Canada, and provided education and counseling to build insight into their FND diagnosis. Patient-determined diagnostic agreement at follow-up was categorized as a binary variable: (i) symptoms attributable primarily to FND or (ii) attributable to another cause (neurological disease or unknown). One-year symptom status was patient-reported on a 7-point scale (-3 to +3), with scores \u22652 defined as meaningful improvement. Return to work/school was assessed as an indicator of global improvement of functional status. Univariate tests screened variables for inclusion in multivariate logistic regression models, which evaluated associations between diagnostic agreement and other outcomes. A total of 282 patients with FND were assessed (mean age 38.9\u00a0\u00b1\u00a012.0\u00a0years; 80.3% female), and of these, 127 had 1-year follow-up data. FND subtypes included functional movement disorder (functional weakness [26.8%], hyperkinetic movement [15.7%]), seizure (15.0%), sensory (16.5%), functional cognitive disorder (7.9%), persistent postural perceptual dizziness (14.2%), and speech/swallowing (3.9%). Diagnostic agreement was significantly associated with symptom improvement (odds ratio [OR]\u00a0=\u00a03.81, 95% CI: 1.33-11.71, p\u00a0=\u00a00.015) and global improvement (OR\u00a0=\u00a05.74, 95% CI: 1.11-37.54, p\u00a0=\u00a00.047). Psychiatric comorbidity (p\u00a0=\u00a00.026), childhood trauma (p\u00a0=\u00a00.015), and psychological triggers (p\u00a0=\u00a00.013) were associated with diagnostic agreement, while ongoing medical/neurological workup was linked to disagreement (p\u00a0<\u00a00.001). Diagnostic agreement was associated with symptom improvement and return-to-work/school status in FND patients who received a neuroscience-informed education and counseling assessment. However, given the observational design and lack of baseline measurement of diagnostic agreement, the directionality of this relationship cannot be determined.\n\nID: 42418163\nTitle: Construction of a Prediction Model for Naming Recovery in Subacute Poststroke Aphasia Based on Multivariate Analysis: Evaluation of Accuracy and Reliability.\nAbstract: Anomia, a common dysfunction in poststroke aphasia (PSA), impacts daily communication, and its prognosis remains challenging. This study aimed to develop a model to predict naming rehabilitation in patients with subacute PSA. Data of PSA were collected retrospectively. Logistic regression (LR) analyses by a nested fivefold cross-validation were performed to identify predictors and construct a predictive model. The efficacy of the model was evaluated using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA). Additionally, the net reclassification index (NRI) and integrated discrimination improvement (IDI) were calculated to assess the discrimination of the model. Shapley additive explanation (SHAP) values were utilized to determine the prediction role of each feature in the model. To reduce the variance of the best model, data resampling was performed using fivefold cross-validation and three distinct random seeds. A total of 199 patients and 21 clinical variables were analyzed. Lesion site, Broca's area damage, education level, Boston Diagnostic Aphasia Examination grade, and transcranial direct current stimulation (tDCS) therapy were significant in \u2265 50% of inner folds across three different random seed conditions in univariate LR analysis and were incorporated into the predictive model. The model achieved the mean area under the curve in the fivefold cross-validation, surpassing the single-predictor models (Seed 42: 0.792 \u00b1 0.099; Seed 123: 0.828 \u00b1 0.045; Seed 456: 0.816 \u00b1 0.065). The ROC curves, calibration curves, and DCA demonstrated high accuracy, consistency, and clinical utility in the prediction of rehabilitation of PSA. Furthermore, the NRI and IDI indicated that the model offered better discrimination than single-predictor models. The model showed high balanced accuracy (Seed 42: 0.892 \u00b1 0.031; Seed 123: 0.874 \u00b1 0.061; Seed 456: 0.883 \u00b1 0.074). The SHAP analysis identified the importance of these features. Notably, tDCS, as the sole modifiable core factor, holds a prominent position in the predictive model, highlighting its potential therapeutic value in accelerating language functional recovery through the facilitation of neuroplasticity. However, its therapeutic efficacy is modulated by stimulation target status (Broca's area integrity), suggesting that alternative therapeutic targets may be explored for patients with Broca's area damage. The predictive model demonstrated a strong performance and may assist clinicians in stratifying patients with aphasia for early intervention, thereby potentially improving rehabilitation outcomes. https://doi.org/10.23641/asha.32774427.\n\nID: 42417819\nTitle: Montreal Cognitive Assessment Hearing Impairment (MoCA-H) in brazilian portuguese: performance analysis.\nAbstract: To analyze the performance of the Montreal Cognitive Assessment Hearing Impairment (MoCA-H) in Brazilian Portuguese in neurologically healthy older adults, comparing those with normal hearing and those with hearing loss who use hearing aids. Observational, cross-sectional, and quantitative study involving 20 neurologically healthy older adults (with no signs of cognitive decline), matched by age and education, divided into two groups: one with a quadritonal average within normal limits, and the other with bilateral moderate or greater hearing loss, all users of bilateral Hearing Aids (HA). Participants were assessed through anamnesis, pure-tone audiometry, speech audiometry, tympanometry, Mini-Mental State Examination (MMSE), and MoCA-H. Comparisons between groups were conducted using Student's t-test, with a significance level of 5%. Similar performance was observed between groups in seven of the eight cognitive domains assessed by the MoCA-H. The only statistically significant difference was found in the visuo-spatial/executive domain, with lower performance in the group with hearing loss. No significant difference was found in the total MoCA-H score between the groups. Neurologically healthy older adults with and without treated hearing loss showed similar performance on the MoCA-H tasks. Only the visuospatial/executive task distinguished the groups evaluated. The MoCA-H proved to be an effective and sensitive tool in the cognitive assessment of older adults with moderate to severe hearing loss, at least in the sample studied. Analisar o desempenho do Montreal Cognitive Assessment Hearing Impairment (MoCA-H) em portugu\u00eas brasileiro em idosos neurologicamente saud\u00e1veis, comparando aqueles com audi\u00e7\u00e3o normal e com perda auditiva usu\u00e1rios de pr\u00f3teses auditivas. Estudo observacional, transversal e quantitativo, com 20 idosos neurologicamente saud\u00e1veis (sem sinais de decl\u00ednio cognitivo), pareados por idade e escolaridade, divididos em dois grupos: um com m\u00e9dia quadritonal dentro da normalidade e outro com perda auditiva bilateral de grau moderado ou superior, usu\u00e1rios de Aparelhos de Amplifica\u00e7\u00e3o Sonora Individual (AASI). Os participantes foram avaliados por meio de anamnese, audiometria tonal liminar, logoaudiometria, imitanciometria, Mini Exame do Estado Mental (MEEM) e MoCA-H. As compara\u00e7\u00f5es entre os grupos foram realizadas com o teste t de Student e Mann Whitney com n\u00edvel de signific\u00e2ncia de 5%. Observou-se desempenho semelhante entre os grupos em sete das oito habilidades avaliadas pelo MoCA-H. A \u00fanica diferen\u00e7a estatisticamente significativa foi identificada no dom\u00ednio visuo-espacial/executivo, com desempenho inferior no grupo com perda auditiva. A pontua\u00e7\u00e3o total do MoCA-H n\u00e3o apresentou diferen\u00e7a significativa entre os grupos. Os idosos neurologicamente saud\u00e1veis sem e com perda auditiva tratada apresentaram desempenho semelhante nas tarefas do MoCA-H. Apenas a tarefa visuo-espacial/executivo distinguiu os grupos avaliados. O MoCA-H mostrou-se uma ferramenta eficaz e sens\u00edvel na avalia\u00e7\u00e3o cognitiva de idosos com perda auditiva moderada \u00e0 severa, ao menos na amostra estudada.\n\nID: 42417178\nTitle: Performance and Biases of the LENA and ACLEW Algorithms in Analyzing Language Environments in Down, Fragile X, Angelman Syndromes, and Populations at Elevated Likelihood for Autism.\nAbstract: Wearable recorders are used in research and clinical practice to collect and measure children's vocalizations and the language environment in which they occur. Recordings generate vast amounts of audio, making manual analysis impractical and requiring automated processing. Two automated algorithms have emerged: the proprietary LENA (Language ENvironment Analysis) and the open-source ACLEW (Analyzing Child Language Experiences around the World) systems; yet, systematic performance comparisons remain scarce. Here, we validate and compare the performance of these two algorithms across key measures: audio segmentation into speaker categories, conversational turn count (CTC), adult word count (AWC), and child vocalization count (CVC). This analysis is based on 25 h of manually annotated audio recordings from 50 age-matched U.S. children with diverse neurodevelopmental profiles: children with Down syndrome, Fragile X syndrome, and Angelman syndrome, children at elevated likelihood of autism, and low-risk controls. We hypothesized that the algorithms might be less accurate for children with neurodevelopmental conditions, since these children often show different patterns of volubility and vocal maturity compared to the typically developing children used to train the algorithms. Thus, we assessed the performance of algorithms across diagnostic groups, a crucial validation step for both cross-population research and the evaluation of language interventions. Results reveal that while algorithms achieve similar performance across groups, they show different patterns: LENA makes fewer segmentation mistakes but misses many segments (identification error rate = 81.3%, percent correct = 45.3%), while ACLEW shows the opposite pattern (identification error rate = 129.4%, percent correct = 69.4%). Both LENA and ACLEW achieve reasonable levels of accuracy in their automatic counts (Pearson's r ranging from 0.78 to 0.92) and maintain stable performance across diagnostic groups. We conclude with recommendations for the validation and potential use of these algorithms in research and clinical practice. SUMMARY: Our comparison of the LENA and ACLEW algorithms in analyzing children's language environment and vocal production across five neurodevelopmental profiles reveals similar performance but distinct error patterns. LENA makes fewer errors but misses speech (81.3% error rate, 45.3% correct); ACLEW makes more errors but captures more speech (129.4% error rate, 69.4% correct). Both algorithms maintain consistent performance across diagnostic groups, supporting their reliability for research with these 2-year-old populations with diverse neurodevelopmental profiles. Variations in algorithm performance are primarily driven by the total speaking time of surrounding speakers (other children and adults), rather than the diagnostic group.\n\nID: 42416808\nTitle: Classifying voice disorders for machine learning: a pilot study using the USVAC-C2025 diagnostic framework.\nAbstract: Machine learning for voice disorders relies heavily on accurate diagnostic classification, yet progress has been limited by inconsistent labelling and the absence of a reproducible framework suitable for clinical and computational use. This study aimed to develop and evaluate a multilayer classification system for voice disorder diagnosis tailored for machine learning applications, and to determine its inter- and intra-rater reliability among otolaryngologists and speech-language pathologists. We conducted a diagnostic reliability study of 45 adults with voice disorders who underwent comprehensive clinical assessment, including videostroboscopy, at a tertiary voice clinic in Sydney, Australia, between February 2018 and March 2024. A multidisciplinary team developed a five-level hierarchical classification framework through iterative consensus. Four blinded raters independently applied the framework to anonymised video and clinical datasets, with 15 cases randomly repeated for intra-rater analysis. Reliability was quantified using Fleiss \u03ba statistics and intraclass correlation coefficients across all diagnostic levels. Intra-rater reliability was high (intraclass correlation coefficient range, 0.768-0.865), with comparable consistency across disciplines. Inter-rater reliability was strongest for identifying disordered vs. non-disordered voices (\u03ba = 0.812; 95% CI, 0.733-0.891) and major aetiological categories (\u03ba = 0.695; 95% CI, 0.611-0.779), supporting the utility of structured classification for foundational diagnostic decisions. Agreement declined with increasing diagnostic specificity, particularly for perceptually based conditions such as muscle tension disorders (\u03ba = 0.253; 95% CI, 0.172-0.334) and vocal fold paresis (\u03ba = 0.238; 95% CI, 0.155-0.321). Functional neurological voice disorders and structural lesions demonstrated the highest category-level agreement. These findings show that a structured, multilayer framework improves diagnostic consistency where machine learning systems most rely on stable labels and highlights key areas of diagnostic ambiguity. The system provides a practical foundation for creating reliable annotated datasets and supports future development of machine learning tools for voice disorder classification and clinical decision support.\n\nID: 42416267\nTitle: Reported symptoms and patterns of language impairment in bilingual speakers with primary progressive aphasia: a retrospective study.\nAbstract: The relative scarcity of studies of bilingual speakers with primary progressive aphasia (PPA) leads to knowledge gaps regarding their symptoms and patterns of language impairment. It is unknown if PPA symptoms in bilingual speakers differ from those of monolingual speakers. In addition, it remains unclear if one of a bilingual speaker's languages is more vulnerable to the onset of symptoms and/or is better preserved. Furthermore, bilingualism factors (e.g. order/age of language acquisition (L1/L2) and language dominance) may explain patterns of impairment both within and across the variants of PPA. To characterize the bilingualism factors, speech and language symptoms, and patterns of language impairment in a retrospective cohort of bilingual speakers with PPA. In a large cohort (N = 69) of bilingual speakers, we performed a chart review to extract information regarding self/caregiver-reported PPA symptoms, first language impacted by PPA at symptom onset, less preserved language at time of evaluation, and bilingual history factors (age/order of acquisition (L1/L2) and language dominance). We explored how emergence and presentation of symptoms associated with bilingualism factors. The presenting symptoms were mostly consistent with current PPA diagnostic criteria, although symptoms unique to bilingual speakers were reported. The language reported to first be impacted by PPA, as well as the less preserved language at the time of evaluation, was generally reported to be the less dominant language, regardless of PPA variant. These measures did not associate as closely with age/order of acquisition (L1 versus L2). Bilingual speakers with PPA may report additional symptoms that reflect their ability to speak more than one language. The less dominant language was most susceptible to the initial impact of PPA and also tended to the less preserved language at the time of evaluation. Future studies of bilingual speakers with neurodegenerative diseases should systematically consider bilingualism factors, which are likely to contribute to clinical presentation and disease progression.\n\nID: 42416005\nTitle: The interdisciplinary fibreoptic endoscopic evaluation of swallowing assessments in ICU patients: A file review.\nAbstract: Dysphagia is a complex condition common in critical care settings, often resulting from multifactorial causes such as trauma, neuromuscular weakness, impaired cognition, intubation and the presence of a tracheostomy. Dysphagia can have serious consequences, including aspiration pneumonia and prolonged hospital stays, which need to be avoided in resource-constrained environments such as South Africa (SA). To investigate the characteristics of dysphagia in critically ill patients using an interdisciplinary assessment approach that utilises both bedside evaluations and fibreoptic endoscopic evaluation of swallowing (FEES). A retrospective file review was conducted of 68 adult patients who underwent interdisciplinary dysphagia assessments in a private SA hospital between July 2022 and January 2024. Data collected included clinical notes, anatomical and physiological markers, Penetration-Aspiration Scale (PAS) scores and post-assessment diagnoses. Descriptive statistics were employed to analyse variables such as age, gender, comorbidities and dysphagia symptoms. The mean age of participants was 59.5 years (standard deviation (SD) 17.05 years), with the majority presenting with trauma-related injuries or cerebrovascular accidents. Dysphagia was prevalent, with 49% of patients exhibiting significant swallowing difficulties. The mean PAS score was 3.44 (SD 2.82), indicating that material often entered the airway without being ejected. Notably, 17% of patients presented with silent aspiration, highlighting the need for comprehensive interdisciplinary assessment techniques. Common symptoms included pooling, dysphonia and delayed swallow triggers, which may be identified at the bedside and confirmed using FEES. Patients were referred to speech-language therapy (SLT) after a median of 13 days in the intensive care unit (ICU). Dysphagia is a significant concern in critical care, necessitating early and co-ordinated assessment strategies to minimise complications and improve patient outcomes. This study advocates enhanced protocols and interdisciplinary collaboration to manage dysphagia effectively. Early referral to SLT is critical for timely intervention, which is essential in an under-resourced setting. Future research across various settings is needed to further validate the interdisciplinary model of dysphagia assessment and management and to generate additional local data on dysphagia in the ICU. This retrospective file review demonstrates the prevalence, clinical features, and consequences of dysphagia among critically ill adults assessed with an interdisciplinary FEES approach in a South African (SA) ICU. The study contributes to important local evidence by (i) quantifying the burden of dysphagia and silent aspiration in an ICU population, (ii) showing that interdisciplinary FEES (SLP + ENT) augments the standard bedside dysphagia assessment and yields important diagnostic detail that informs safer feeding and management decisions, and (iii) identified substantial delays to SLT for assessment that likely increase the risk of complications such as aspiration pneumonia. These findings support calls for earlier SLT involvement, development of context-appropriate referral pathways and practice guidelines, and wider adoption of interdisciplinary assessment models in resource-constrained SA ICU settings.\n\nID: 42415806\nTitle: A novel class-attention transformer-driven feature fusion technique-based speech disorder classification.\nAbstract: Speech disorders (SD) present significant diagnostic challenges due to the complex and indistinct acoustic characteristics embedded within speech signals. The standalone convolutional neural networks (CNNs) and vision transformers (ViT) struggle to capture SD temporal and spectral dynamics. To address these limitations, this study proposes an end-to-end binary pathological SD detection framework that processes raw audio waveforms to differentiate disordered speech from healthy speech while improving feature representation, interpretability, and generalization. A hybrid feature extraction integrating one-dimensional CNNs and ViT's self-attention mechanism is developed to extract crucial SD features. An adaptive fusion and a Class-attention transformer (CaiT)-based feature refinement is introduced to transform the extracted features into a classification-optimized global representation. Through the integration of gradient-weighted class activation mapping (Grad-CAM) and attention-based visualization with the model architecture, the temporal-localization of disorder-relevant acoustic patterns is enabled. Two benchmark datasets are utilized for model's performance evaluation, benchmarking against state-of-the-art CNNs and ViT architectures. The model is trained and internally validated on the SVD dataset using subject-level splitting, while the PD and VOICED datasets are used exclusively for external validation to assess cross-dataset generalization across neurological and heterogeneous pathological voice conditions. The proposed model achieves 97.50% accuracy on both SVD and PD datasets and 95.80% accuracy on VOICED, while maintaining a lightweight design with 5.2 million parameters. Statistical analysis further confirms the results' reliability and significance. The integration of adaptive fusion and transformer-based refinement significantly enhances SD detection performance while ensuring interpretability. The suggested framework offers a sound and proof-of-concept for diagnosing SD, allowing clinicians and speech-language pathologists to make reliable predictions and pay attention to diagnostically significant time intervals.\n\nID: 42415081\nTitle: Generating Alzheimer's narratives using large language models.\nAbstract: Analyzing semi-spontaneous speech is a promising direction for supporting Alzheimer's disease (AD) assessment, yet progress is limited by the scarcity of annotated clinical data. Large Language Models (LLMs) offer new opportunities to generate synthetic narratives that may resemble speech patterns of both patients with AD and healthy controls during cognitive evaluation tasks such as the Cookie Theft Picture description. This study evaluates whether models including GPT, T5/Flan-T5, LLaMA, Mistral, and Qwen can generate clinically plausible picture-description narratives under two configurations: Human-to-Bot, where an LLM responds directly to real interviewer prompts, and Bot-to-Bot, where two LLMs simulate both interviewer and participant roles. Models were fine-tuned on transcripts from the DementiaBank Pitt Corpus and assessed using lexical and semantic metrics, as well as human expert ratings. Generated narratives were further used to augment training data for an AD vs. healthy control classifier based on BERT embeddings and an MLP architecture. LLMs differed substantially in their ability to reproduce clinically meaningful and semantically coherent narratives of patient-interviewer interactions. Mistral, LLaMA, and Qwen achieved the strongest automatic evaluation metrics, e.g., BERTScores above 0.90 in the Human-to-Bot condition-and produced narratives rated by human experts as fluent, plausible, and diagnostically informative. When combining real and synthetic narratives for classifier training, the highest F1-score reached 0.84, outperforming models trained on real data alone (F1\u2009=\u20090.74). Synthetic data generated in Human-to-Bot settings contributed most to diagnostic improvements, whereas Bot-to-Bot interactions exhibited greater variability and reduced clinical realism. LLMs can generate high-quality synthetic narratives that enhance downstream AD classification and show promising clinical plausibility in cognitive assessment contexts. Incorporating LLM-generated data provides a scalable strategy for mitigating data scarcity in dementia research. Future work should focus on improving fully synthetic dialogue quality, expanding multilingual capabilities, and refining evaluation frameworks to better capture clinically relevant linguistic features.\n\nID: 42414200\nTitle: Creak Derived from CAPE-V Sentences in Patients with AdLd and pMTD.\nAbstract: The purpose of this study was to evaluate whether acoustic creak (%) derived from the\u00a0Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) sentences differentiates adductor laryngeal dystonia (AdLD) from primary muscle tension dysphonia (pMTD). In this retrospective study, acoustic recordings from 42 patients (21 with AdLD and 21 with pMTD) at a tertiary voice center were analyzed. Participants produced six CAPE-V sentences during a standardized voice evaluation. Recordings were segmented and analyzed using an automated algorithm to compute percent creak (%), defined as creak duration relative to total voicing duration. Smoothed cepstral peak prominence (CPP) was also extracted. Hierarchical binomial logistic regression models evaluated whether creak alone or creak in combination with CPP predicted the diagnostic group. Mean creak (%) values were comparable between groups. Creak (%) did not significantly predict the\u00a0diagnostic group (P > 0.05). Inclusion of CPP did not improve model performance. Creak distributions were positively skewed in both groups, with notable interindividual variability. Creak derived from CAPE-V sentences does not differentiate AdLD from pMTD. These findings suggest that stimulus characteristics, particularly sentence length and the\u00a0associated respiratory-phonatory demands, may influence the discriminative validity of creak. Further research is required to clarify its clinical utility across speech tasks.\n\nID: 42414106\nTitle: Perceived changes in alcohol effects after metabolic and bariatric surgery and one-year alcohol-related outcomes: the moderating role of anxiety.\nAbstract: Metabolic and bariatric surgery (MBS) is associated with changes in perceived alcohol effects, with stronger and faster effects often reported. However, the prospective implications of these changes remain unclear. To examine whether perceived changes in alcohol effects 6months after MBS predict alcohol-related outcomes at 1year and whether psychological vulnerability moderates these associations. Four Belgian hospitals. Two hundred and five adults were assessed preoperatively and at 6 and 12 months postoperatively (73.5% retention). Perceived changes in alcohol effects were measured at 6 months. Alcohol use, drinking motives, and anxiety were assessed at baseline and 12 months. Three separate 2 \u00d7 2 analyses of covariance tested main and interaction effects of perceived change (increase vs. no change) and anxiety (high vs. low) on 12-month outcomes, controlling for baseline levels. Bootstrap regression models assessed robustness. At 6 months, 54.1% reported stronger and/or faster alcohol effects. Significant perceived change \u00d7 anxiety interactions were observed for alcohol use (F(1,200) = 7.33, P < .01), enhancement motives (F(1,200) = 11.95, P < .001), and coping motives (F(1,200) = 6.94, P < .01). Interaction effects for enhancement (B = 1.23, P = .02) and coping motives (B = .96, P = .04) remained significant in bootstrap analyses, whereas the interaction for alcohol use was attenuated (B = 2.76, P = .09). Perceived increases in postoperative alcohol effects were associated with stronger enhancement and coping motives, particularly among individuals with elevated anxiety. Assessing perceived alcohol sensitivity and psychological vulnerability may help identify patients at increased risk for alcohol-related problems.\n\nID: 42413280\nTitle: Machine learning and mobile sensing for naturalistic infant behavior (0-36 months): A comprehensive review and research agenda.\nAbstract: The recent rapid development of mobile and wearable sensing technologies and computational modeling has allowed for high-density and continuous measurement of infants' real-world behavior in natural settings. However, developmental science still struggles practically and methodologically to capture, label, integrate, and understand these data streams, especially in a way that is generalizable and inclusive. This review explores the state of the art in sensing and machine learning (ML) methods to study infants 0-36 months in natural environments. It delineates (i) sensing technologies, (ii) data collection and annotation approaches, (iii) ML approaches for behaviour recognition, prediction and modelling, and (iv) translational paths towards screening and early intervention, with a focus on feasibility, inclusivity, and ethics. A systematic review of literature published between 2015 and 2025 was performed in the following databases (Scopus, Web of Science, PubMed, IEEE Xplore, ACM), in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Inclusion criteria involved studies of infants between 0 and 36 months, naturalistic or free-flowing contexts, and mobile/wearable sensing, computer vision, signal processing or ML. The review examined the sensor modalities (egocentric and exocentric camera and microphone, inertial measurement unit/actigraphy, physiological sensors), data properties (temporal resolution, density, duration), and settings (home, clinic, community). The synthesis places a primary emphasis on naturalistic motor behavior, which is the area most well-represented in the studies included. Selectively considered sensing and ML evidence for vocal and communicative behavior (including language exposure and caregiver-infant interaction), social-affective behavior, and sleep-wake regulation are presented where relevant. It also explored ML paradigms (supervised, semi- and weakly supervised, self-supervised, multimodal, sequential, and transformer-based), validation approaches, and reporting quality.\n\nID: 42412504\nTitle: [Multidisciplinary Assessment of Neurocognitive Disorders: Findings from a Day Hospital and the Influence of Educational Level].\nAbstract: Neurocognitive disorders represent a major public health challenge. We report the experience of a diagnostic day hospital that systematically integrates both a clinical pharmacist and a speech-language pathologist in a socioeconomically advantaged area. This retrospective study included patients undergoing their initial assessment at the day hospital. The primary objective was to describe their neurocognitive, pharmaceutical, and speech-language characteristics. As a secondary objective, we investigated differences according to educational level in pharmaceutical and speech-language assessments and recommendations. A total of 110 patients were included. Polypharmacy was identified in 55% of patients, and at least one pharmaceutical intervention was recommended in 75%. A high prevalence of language disorders was observed, leading to referral for speech therapy in 61% of cases. Compared with the general population consulting for neurocognitive disorders, our patients had a higher average sociocultural level. No significant differences according to educational level were observed in pharmaceutical or speech-language assessment outcomes. These findings highlight the potential value of integrating clinical pharmacy and speech-language pathology into multidisciplinary neurocognitive assessment pathways.\n\nID: 42411744\nTitle: An Early Lexical Screening Tool for British English: Psychometric Properties and Clinical Utility.\nAbstract: Existing direct measures of vocabulary for ages 2-3 years are insufficient as vocabulary increases to include nouns, verbs, adjectives and adverbs, reflecting qualitative changes that support emerging grammatical abilities. The present study aims to establish the psychometric properties and validate a lexical screening tool for 19-36-month-old British English-speaking children, the WinG (Words in Game) test. Specifically, it examines gender differences in internal consistency, concurrent validity and predictive gender invariance across comprehension and production tasks. In addition, the study evaluates the diagnostic accuracy of the tool by establishing clinical cut-off scores to distinguish children with typical versus at-risk language development. Finally, it presents developmental trends in toddlers' aggregate lexical comprehension and production scores, reported in percentiles and stratified by gender. Participants were 336 English-speaking children aged 19-36 months. Sub-set of 85 children were screened with the Words in Game (WinG) test and the Preschool Language Scale (PLS-4). The PLS-4 scores were used as reference tests to ascertain psychometric properties and estimate the sensitivity and specificity of the WinG comprehension and production tasks. Girls outperformed boys on both comprehension and production tasks. The WinG comprehension and production tasks showed strong concurrent validity, with scores positively and highly correlated with the PLS-4 reference measures. Predictive gender invariance was also demonstrated, as both WinG dimensions predicted PLS-4 scores equivalently across genders. Using the 15th percentile as a cut-off, the WinG test demonstrated fair sensitivity for comprehension and good sensitivity for production, though specificity was below the desirable threshold for both tasks. The tool provides a valuable starting point for identifying early receptive and expressive lexical difficulties through direct assessment by speech and language therapists (SLTs). Clinical implications and limitations are also discussed. What is already known on this subject Lexical receptive and expressive abilities emerge and expand rapidly in the second and third years of life. Clinicians and Speech and Language therapists (SLTs) need a systematic, reliable tool to observe the early lexical skills of toddlers. What this study adds to existing knowledge This study established the psychometric properties and validated the Words in Game (WinG) test from a large sample of 19-36-month-old British English learning children to measure the receptive and expressive nouns and predicates (verbs, adjectives and adverbs). The PLS-4 scores were used as a reference standard test. The WinG comprehension and production tasks showed strong concurrent validity, with scores positively and highly correlated with the PLS-4 reference measures. The developmental trends in toddlers' lexical comprehension and production scores are reported in percentiles and stratified by gender. The diagnostic accuracy of the WinG test was ascertained, performing receiver operating curves (ROC) on comprehension and production WinG tasks, entering the 15th percentile clinical cut-off scores, as indicated by the PLS-4 reference measures. What are the clinical implications of this study? The WinG test is a valid tool designed to screen the comprehension and production of words of British English children in the second and third years of life. The WinG test is a tool to be administered by professionals with expertise in language development, such as SLTs. Thanks to its systematic, direct observation approach and validation against established measures, the WinG test demonstrates fair psychometric properties. It provides SLTs with a reliable tool for early screening of toddlers' lexical skills to identify language delays or disorders.\n\nID: 42410568\nTitle: Cleidocranial dysplasia with complex oral manifestations: a case report.\nAbstract: Cleidocranial dysplasia (CCD) is a rare inherited skeletal disorder characterized by distinctive skeletal and dental abnormalities, often leading to delayed or missed diagnosis. Dental findings are frequently the most prominent clinical features and may play a key role in identifying the condition. A 16-year-old girl presented with missing permanent teeth, impaired mastication and esthetic concerns. The patient had previously been diagnosed with growth delay despite normal endocrine evaluation, including growth hormone stimulation testing. The diagnosis of CCD was suspected during dental examination based on characteristic clinical and radiographic features. Clinical assessment revealed short stature, clavicular hypoplasia with shoulder hypermobility and typical craniofacial features. Intraoral findings included prolonged retention of primary teeth, delayed eruption of permanent dentition and Class III malocclusion. Radiographic and CBCT imaging confirmed multiple impacted and supernumerary teeth, delayed cranial suture closure and additional skeletal abnormalities consistent with CCD. A conservative, stage-based treatment approach was adopted to coordinate future surgical and orthodontic interventions according to skeletal maturity. A removable partial denture (RPD) was provided as an interim solution, resulting in improved mastication, speech and esthetics. This case emphasizes the important role of dental professionals in recognizing undiagnosed systemic conditions such as CCD. Early identification based on dental findings and appropriate timing of intervention are essential for optimizing functional and esthetic outcomes.\n\nID: 42409067\nTitle: Clinical Practice Guideline for the Diagnosis and Management of Tinnitus in Korea.\nAbstract: Standardized, evidence-based guideline for tinnitus management is currently lacking in Korea. This guideline aims to provide evidence-based recommendations for the diagnosis and management of tinnitus in Korean adults, adapted to the Korean healthcare system. A multidisciplinary panel (eight otorhinolaryngologists, one neurologist, one psychiatrist, and one audiologist) conducted systematic literature searches up to 2025 using PubMed, Embase, Cochrane Library, KoreaMed, and KMBASE. Evidence quality was assessed using the GRADE methodology. Nine key clinical questions (KQs) were developed in PICO format, and recommendations were finalized through a modified Delphi process (\u226580% agreement threshold). Imaging is recommended for the evaluation of patients with pulsatile tinnitus or asymmetric hearing loss (Grade B). Tinnitus retraining therapy (TRT) and cognitive behavioral therapy (CBT) are conditionally recommended for patients with tinnitus (Grade B). Hearing aids are conditionally recommended for patients with tinnitus and coexisting hearing loss (Grade B). Sound therapy is conditionally recommended to reduce tinnitus-related distress (Grade B). Neuromodulation (transcranial direct current stimulation (tDCS) or repetitive transcranial magnetic stimulation (rTMS)) is conditionally recommended as an adjunctive treatment (Grade B). Routine zinc and vitamin supplementation are strongly recommended against for tinnitus symptom improvement (Grade D\u2020), whereas Ginkgo biloba may be considered for patients with subjective tinnitus (Grade B). Most available evidence was predominantly of low or very low certainty. This guideline provides the first comprehensive evidence-based framework for tinnitus management in Korea. Behavioral and rehabilitative interventions provided the strongest evidence for reducing tinnitus-related distress. Considerations of Korean National Health Insurance coverage, regional accessibility, and patient preferences were integrated throughout the guideline development process. The primary therapeutic goal is to reduce tinnitus-related distress and improve functional outcomes, thereby enhancing overall quality of life.\n\nID: 42405995\nTitle: The Effect of Participation in the Let's Play Program on Autistic Children's Engagement and Caregiver Well-Being: A Randomized Controlled Trial.\nAbstract: In Aotearoa New Zealand (NZ), families face persistent barriers to accessing evidence-based early support for Autistic children. This randomized controlled trial (RCT) evaluated the effectiveness of Let's Play; a bespoke, caregiver-mediated early support program for Autistic children and their caregivers. This single-blind (rater) RCT included 91 parent-child dyads, randomly assigned to the Let's Play program (active support; AS [n\u2009=\u200945]) or a waitlist control (WLC; n\u2009=\u200946). Participants were caregivers of children aged 0 to 5 years with a formal diagnosis or characteristics of autism. Let's Play was delivered over 9 weeks via group workshops and in-home coaching. Primary child and caregiver outcomes, assessed at baseline, post-support, and 6-month follow-up, included parent-child engagement and parental stress, respectively. Children showed descriptive evidence of improvement in caregiver-child engagement, health-related quality of life and behaviour from baseline to post-support. Improvement in parental stress, depression and anxiety symptoms, and self-perceived parenting competence were also evident, across timepoints. However, there were no significant Group x Ttime effects for caregiver-child engagement, number of utterances or number of different words. A Group x Time effect was evident for all other child and caregiver outcome variables, underscoring the benefits of Let's Play. This research provides preliminary evidence of the effectiveness of a low-intensity, community-based, caregiver-mediated early support program for Autistic children's health-related quality of life and behavior and caregiver well-being. However, more targeted or sustained approaches to supporting caregiver-child engagement and vocal communication may be needed for improvement to be observed. The research protocol was prospectively registered on the Australian New Zealand Clinical Trials Registry (ACTRN12622001139763).\n\nID: 42405869\nTitle: Estimating Performance Using Tonotopic Measurements of Intracochlear Electrocochleography: Comparison of Lateral Wall and Perimodiolar Arrays.\nAbstract: To assess intracochlear electrocochleography (ECochG) for estimating cochlear implant (CI) performance for lateral wall and perimodiolar electrode arrays. Prospective cohort study. Tertiary referral center. From December 2021 to June 2024, ECochG was measured intraoperatively using the Active Insertion Monitoring (AIM) system by Advanced Bionics. After insertion, multifrequency tone bursts were delivered via a sound tube from 250\u2009Hz to 2\u2009kHz at 95 to 105\u2009dB HL with recordings at each internal electrode. Using spectral analysis, the maximal amplitude (MA) response electrode was identified by frequency and summed into a single value of total response (MA-ECochG-TR). Postoperative CI performance was routinely monitored. Of 57 participants with ECochG recordings, 43 completed 6-month testing. Of these, 23 were perimodiolar (Mid-Scala [MS]), and 20 were lateral wall (SlimJ [SJ]). MA-ECochG-TR had a moderately strong positive correlation to 6-month consonant-nucleus-consonant (CNC) word scores for MS cases (r\u2009=\u20090.73, 95% CI [0.46-0.88], P\u2009<\u2009.001), but showed no significant correlation for SJ cases (r\u2009=\u20090.04, 95% CI [-0.41 to 0.47], P\u2009=\u2009.87). For the 13 SJ recipients without electroacoustic stimulation (EAS), there was a moderate, non-significant positive correlation between MA-ECochG-TR and 6-month CNC (r\u2009=\u20090.44, 95% CI [-0.14 to 0.80], P\u2009=\u2009.13). MA-ECochG-TR independently estimates performance for perimodiolar arrays. Intracochlear ECochG is less predictive for lateral wall arrays; this may be due to confounding from EAS (though this was not statistically significant) or from signal degradation with a larger electrode-modiolar distance.\n\nID: 42405480\nTitle: Neuroticism and functional burden in chronic dizziness: A clinical cross-sectional observational study using the Eysenck Model and Dizziness Handicap Inventory.\nAbstract: BackgroundChronic dizziness is a multidimensional condition often influenced by psychological factors. Among these, personality traits such as neuroticism have been linked to heightened symptom perception and disability. However, few studies have systematically examined the relationship between neuroticism, functional burden, and diagnostic characteristics in a population with clinical dizziness.ObjectiveTo investigate the relationship between perceived dizziness-related handicap and neuroticism as a personality trait among patients referred to a multidisciplinary dizziness and balance clinic.MethodsThis observational study included 247 adult patients with persistent dizziness referred to a specialist clinic. Patients completed the Eysenck Personality Questionnaire (EPQ) and the Dizziness Handicap Inventory (DHI). Clinical data included diagnosis category, duration of symptoms, fall history, comorbidities, and consultation history. Statistical analyses included Spearman correlations, ANOVA, chi-square tests, cluster analysis, and multivariate linear regression.ResultsNeuroticism was significantly correlated with higher DHI scores (\u03c1 = 0.39, p < 0.001) and a greater number of healthcare consultations (\u03c1 = 0.19, p = 0.003). It was not associated with duration of symptoms or fall history. A chi-square test indicated a significant association between the neuroticism category and diagnosis category (\u03c72 = 32.02, p = 0.043), with higher neuroticism observed in functional and central disorders. Cluster analysis revealed three psychological-clinical subgroups varying in emotional burden, functional disability, and comorbidity profiles. In regression modelling, neuroticism was the only significant predictor of DHI score (p < 0.001), independent of diagnosis or symptom duration.ConclusionPersonality domains, especially neuroticism, are strong predictors of perceived functional burden in patients with chronic dizziness. These findings underscore the importance of incorporating psychological assessment into the clinical evaluation to further facilitate tailored interventions for the management of dizziness. Personality profiling may help identify high-burden subgroups and guide individualized, multidisciplinary care strategies.\n\nID: 42396248\nTitle: Case Report: Extraforaminal endoscopic lumbar discectomy in two dogs with far-lateral intervertebral disc extrusions.\nAbstract: Far-lateral intervertebral disc extrusions (IVDE) represent an uncommon subset of intervertebral disc disease in dogs, in which disc material is herniated dorsolaterally or laterally to compress the exiting nerve root in an extraforaminal location. While minimally invasive spinal surgery techniques have been described in dogs, to the authors knowledge, full-endoscopic discectomy has not previously been reported for extraforaminal IVDE. This case report describes the clinical presentation, surgical technique, and short-term outcomes of extraforaminal endoscopic lumbar discectomy (EELD) in two dogs. Two middle-aged crossbreed dogs were presented with subacute onset of vocalization, pelvic limb lameness presumed to be a nerve root signature, and marked lumbar hyperaesthesia without other abnormalities on neurological examination. MRI or CT confirmed L5-6 extraforaminal disc extrusion with L5 spinal nerve root compression in both cases. Medical management failed to resolve clinical signs. Using a uniportal approach, a 6.3 mm diameter working-channel endoscope was fluoroscopically docked onto the transverse process of the vertebra caudal to the affected disc, creating a muscle-sparing lateral corridor. Extruded disc material was visualized, released from its fibrous capsule, and removed piecemeal without the need for osteotomy. Surgical times were 25 and 30 min. Post-operative CT confirmed effective decompression in both dogs. Post-operative recovery was rapid, with low pain scores and no requirement for opioid analgesia. Dogs were discharged within 24 h, and by 3 weeks both were free of lameness and spinal pain. At 12 weeks, caregiver-reported outcomes demonstrated sustained improvement, including a substantial reduction in Canine Brief Pain Inventory scores. EELD provided effective decompression through a minimally invasive corridor with excellent early outcomes. This first description in dogs supports further investigation of EELD as an alternative to conventional open surgical approaches for extraforaminal IVDE.\n\nID: 42390100\nTitle: Hearing Aids Reshape Neural Processing of Emotional Speech Without Improving Emotion Perception.\nAbstract: Hearing aids have improved speech intelligibility but not speech emotion perception in older adults with hearing loss. Hearing loss has also been linked to altered brain responses to emotional non-speech sounds, potentially contributing to the speech emotion perception deficits even under aided listening. While fMRI requires hearing aid removal due to metal incompatibility, fNIRS is silent and hearing-aid compatible, creating a novel opportunity to identify neural processes during aided listening. We leveraged fNIRS to examine how hearing aids affect brain function in experienced hearing-aid users during speech emotion perception. Older adults (17 normal hearing, 14 hearing-aid users) judged vocal-emotion changes in speech while fNIRS recorded hemodynamic activity. Hearing-aid users completed the task under aided and unaided listening. Behaviorally, hearing aids did not improve speech emotion perception, replicating prior research. In cortical responses, individuals with hearing loss showed increased planum temporale activity, regardless of hearing-aid use. Unaided listening showed additional frontal recruitment, including increased medial superior frontal gyrus activity and stronger functional connectivity between inferior frontal and superior temporal gyri. Conversely, aided listening increased inferior parietal lobe activity, but reduced connectivity between inferior frontal gyrus and inferior parietal lobe. Together, findings indicate that hearing aids partially modify cortical processing of emotional speech. They reduced reliance on frontal compensatory control systems and increased engagement of a higher-order parietal region, consistent with partial restoration of bottom-up auditory information during aided listening. Persistent abnormalities in early auditory processing and incomplete sensorimotor integration may explain why hearing aids fail to normalize speech emotion perception.\n\nID: 42388861\nTitle: Selective vagus-recurrent laryngeal nerve anastomosis guided by intraoperative neuromonitoring: evidence of lateral motor fiber clustering in the vagus nerve.\nAbstract: Direct anastomosis (DA) is the standard approach after recurrent laryngeal nerve (RLN) transection but is often not feasible due to excessive tension. This experimental study evaluated a novel intraoperative neuromonitoring (IONM)-guided selective vagus-recurrent laryngeal nerve anastomosis (SVRA) technique and compared its immediate electrophysiologic performance with DA in a porcine thyroid surgery model. 18 transected nerves from 9 pigs were randomized to DA or SVRA (9 nerves per group). In the SVRA group, low-current IONM was used to map vagus nerve (VN) motor fibers innervating laryngeal musculature; these fibers were selectively dissected and anastomosed to the transected RLN. In the DA group, end-to-end RLN neurorrhaphy was performed under microscopy. Electromyography (EMG) amplitudes and latencies were recorded at baseline and serially up to 2 hours after anastomosis; hemodynamic parameters were monitored to assess the safety of VN manipulation. VN motor fibers innervating the laryngeal muscles were predominantly localized to the lateral VN and were mostly concentrated in a single strand. After anastomosis, both techniques yielded early EMG recovery, with post-anastomotic amplitudes often exceeding 50% of baseline. A cross-innervation model (left VN to right RLN) produced immediate EMG responses approaching baseline and bilateral vocal fold activation. Moreover, when the anastomosed nerve was pulled, the EMG amplitude varied with the alteration of the relative position of the fiber components at the two severed ends. VN dissection did not cause clinically relevant changes in blood pressure or oxygen saturation, and only minor, non-significant heart rate increases were observed. IONM-guided SVRA enables selective recruitment of VN motor fibers for targeted RLN reconstruction while largely preserving VN trunk integrity. These findings support SVRA as a physiologically grounded and technically feasible reconstructive option that can achieve acute electrophysiological recovery when tension precludes DA during thyroid surgery-related RLN transection, although long-term functional reinnervation remains to be established.\n\nID: 42384656\nTitle: Probability of a timely vocal response in mother-infant interaction and later psychiatric diagnosis: A case-control study.\nAbstract: Patterns of parent-child interactions are commonly cited as being predictive of later psychiatric disorders but precisely which elements of these interactions are important is rarely clear, potentially affecting the effective targeting of interventions in young children. The current study aimed to examine the relationship between timely vocal response during parent-child interactions (i.e., the probability of mothers responding to their child within a specified time period and vice versa), and later psychiatric diagnosis. Drawing on data from the Avon Longitudinal Study of Parents and Children (ALSPAC) cohort, a case control study was conducted based on infant-mother video observations of children assessed for neuropsychiatric disorders using the parent-reported Development and Wellbeing Assessment (DAWBA) at seven years of age (103 controls and 55 cases). Empirical examination suggested that 1 second represented the optimal threshold for maternal responses and 8 seconds for child responses. Only the maternal measure was found to predict later psychiatric disorders, with evidence of associations limited to hyperactivity and conduct disorders. These associations were not sensitive to either maternal education or child sex. The results are discussed in terms of the value of precise interpretation of early mother/child interaction and for the potential for providing targeted intervention to the population concerned.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech\u2011derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1\u2011weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS.\n  --- END ACTUAL ABSTRACT FOR 42333954 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Reduced speaking and articulation rates were associated with thinning in both oral motor cortices.\" (Source: 42333954)\n- \"In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations.\" (Source: 42333954)\n- \"Longitudinal mixed effects models found that the ALS group showed decline on NeuLogiq measures of emotion recognition and speech fluency.\" (Source: 42225765)\n- \"Fifty patients with ALS were included (January 2023 - June 2025), of whom 47 (94%) completed the 3-month follow-up.\" (Source: 42405987)\n- \"Digital endpoints offer an innovative approach to capturing disease progression.\" (Source: 42405987)\n- \"By demonstrating that cortical dysfunction is embedded before degeneration, this work provides a unifying framework connecting early network instability to disease progression and establishes electrophysiological network signatures, detected by machine learning classifiers, as candidate biomarkers for early diagnosis and therapeutic screening.\" (Source: 42267908)\n- \"These parameters demonstrated sensitivity to disease progression and may contribute to early diagnosis, phenotypic stratification, and functional monitoring of ALS.\" (Source: 42329964)\n- \"Receiver operating characteristic (ROC) analyses demonstrated strong discriminative performance for both the gene signature (AUC 0.87-1.00) and the associated miRNAs (AUC 0.95-1.00).\" (Source: 42251967)\n- \"Amyotrophic lateral sclerosis (ALS) lacks reliable, disease-specific, and minimally invasive biomarkers, representing a major barrier to early diagnosis and patient stratification.\" (Source: 42251967)\n- \"Whole-body muscle MRI (WB-MRI) enables comprehensive assessment of muscle involvement and may improve detection of LMN dysfunction.\" (Source: 42296263)\n- \"This resulted in diagnostic upgrading in 14.9% and 25.5% of patients, respectively.\" (Source: 42296263)\n- \"The absence of specific diagnostic biomarkers leads to diagnostic delays, hindering early intervention and management.\" (Source: 42217760)\n- \"Peripheral blood white blood cells, monocytes, HbA1c, and HGI can serve as potential diagnostic biomarkers for ALS.\" (Source: 42211895)\n- \"Combined detection can improve the diagnostic accuracy of ALS, facilitating early diagnosis and intervention, and ultimately improving patient prognosis.\" (Source: 42211895)\n- \"GUSS and RSST demonstrated good discriminative ability for aspiration risk and may be clinically useful bedside screening tools.\" (Source: 42356052)\n- \"He communicated 183,060 sentences-totaling 1,960,163 words-at an average rate of 56 words per minute.\" (Source: 42297978)\n- \"Automated measurement of speaking and articulation rates holds promise as a scalable alternative to manual analysis in clinical populations.\" (Source: 42268776)\n- \"Recent advances in 3D printing have enabled rapid prototyping of lab-on-chip (LOC) platforms that integrate microfluidics, biosensors, and biological models to detect disease-specific biomarkers with high sensitivity and throughput.\" (Source: 42318821)\n- \"To address current gaps, we introduce a standardized evidence grading framework (Tier 1-3) and a comprehensive reporting template for biomarker studies\" (Source: 42217760)\n\n\nINSTRUCTION: Study the actual abstracts provided.

The literature demonstrates that while overt bulbar impairment is a feature of disease progression, advanced signal processing and neuroimaging provide evidence that cortical motor neuron degeneration is embedded in the brain architecture before the overt clinical manifestation of degeneration. Current digital platforms, including automated speech timing measures, allow for the identification of potential prognostic indicators in speech production that bypass the limitations of traditional, rater-dependent scales.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe early detection of ALS remains a clinical challenge due to the reliance on traditional neurological examinations, which often fail to capture subtle bulbar motor neuron degeneration. Research utilizing high-density neuroimaging and digital speech analysis suggests that cortical dysfunction is present before the transition to overt systemic degradation. Specifically, thinning of the oral motor cortex correlates with reduced oral motor function, serving as a sensitive marker for underlying neuronal instability. Longitudinal analysis of speech parameters, such as articulation rates, indicates that these measures capture bulbar decline with greater sensitivity than traditional scoring tools. Furthermore, advanced classification frameworks\u2014ranging from gene-miRNA signatures in PBMCs to machine learning-derived electrophysiological signatures\u2014are defining new diagnostic horizons. The shift toward non-invasive digital endpoints provides a scalable approach to monitor these subtle changes in the pre-symptomatic phase, offering a potential path for earlier intervention.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Thinning of the bilateral oral motor cortices is an anatomical precursor that maps directly to measurable decrements in oral motor function.\n*   Automated speaking and articulation rates provide a robust alternative to manually conducted assessments, which are prone to observer bias.\n*   Digital speech-derived measures demonstrate clear neuroanatomical correlations where standard bulbar subscores in the ALSFRS-R do not.\n*   The use of intracortical brain-computer interfaces (BCIs) has allowed for long-term monitoring, producing datasets with high word accuracy that validate the stability of speech-based tracking.\n*   Cortical dysfunction originates in a developmental trajectory in cultured cortical networks, suggesting that network collapse is a final stage of a long-standing process.\n*   The combination of digital endpoints (spirometry, accelerometry, and speech) yields high protocol adherence, supporting their future integration into standard clinical workflows.\n*   The identification of a gene-miRNA signature in PBMCs provides a molecular foundation that mirrors the central pathology of TDP-43 in ALS.\n*   Machine learning models are increasingly capable of identifying electrophysiological signatures in neuronal networks that predate overt degeneration.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

In 25% of ALS sufferers, speech disorders occur as prodromal symptoms of the disease. Impaired communication affects physical health and has a negative impact on mental and emotional condition. In this study, we assessed which domains of speech are particularly affected in ALS. Subsequently, we estimated possible correlations between the ALS patients' subjective perception of their speech quality and an objective assessment of the speech organs carried out by an expert. The study group consisted of 63 patients with sporadic ALS. The patients were examined for articulatory functions by means of Voice Handicap Index (VHI) and the Frenchay Dysarthria Assessment (FDA). On the basis of the VHI scores, the entire cohort was divided into 2 groups: group I (40 subjects) with mild speech impairment, and group II (23 subjects) displaying moderate and profound speech deficits. In an early phase of ALS, changes were typically reported in the tongue, lips and soft palate. The FDA and VHI-based measurements revealed a high, positive correlation between the objective and subjective evaluation of articulation quality. Deterioration of the articulatory organs resulted in the reduction of social, physical and emotional functioning. The highly positive correlation between the VHI and FDA scales seems to indicate that the VHI questionnaire may be a reliable, self-contained tool for monitoring the course and progression of speech disorders in ALS.

        "33808458": "ID: 33808458\nTitle: Cognitive and Behavioral Manifestations in ALS: Beyond Motor System Involvement.\nAbstract: Amyotrophic lateral sclerosis (ALS) has long been considered to be a purely motor disorder. However, it has become apparent that many ALS patients develop cognitive and behavioral manifestations similar to frontotemporal dementia and the term amyotrophic lateral sclerosis-frontotemporal spectrum disorder (ALS-FTSD) is now used in these circumstances. This review is intended to be an overview of the cognitive and behavioral manifestations commonly encountered in ALS patients with the goal of improving case-oriented management in clinical practice. We introduce the principal ALS-FTSD subtypes and comment on their principal clinical manifestations, neuroimaging findings, neuropathological and genetic background, and summarize available therapeutic options. Diagnostic criteria for ALS-FTSD create distinct categories based on the type of neuropsychological manifestations, i.e., changes in behavior, impaired social cognition, executive dysfunction, and language or memory impairment. Cognitive impairment is found in up to 65%, while frank dementia affects about 15% of ALS patients. ALS motor and cognitive manifestations can worsen in parallel, becoming more pronounced when bulbar functions (affecting speech, swallowing, and salivation) are involved. Dementia can precede or develop after the appearance of motor symptoms. ALS-FTSD patients have a worse prognosis and shorter survival rates than patients with ALS or frontotemporal dementia alone. Important negative prognostic factors are behavioral and personality changes. From the clinician's perspective, there are five major distinguishable ALS-FTSD subtypes: ALS with cognitive impairment, ALS with behavioral impairment, ALS with combined cognitive and behavioral impairment, fully developed frontotemporal dementia in combination with ALS, and comorbid ALS and Alzheimer's disease. Although the most consistent ALS and ALS-FTSD pathology is a disturbance in transactive response DNA binding protein 43 kDa (TDP-43) metabolism, alterations in microtubule-associated tau protein metabolism have also been observed in ALS-FTSD. Early detection and careful monitoring of cognitive deficits in ALS are crucial for patient and caregiver support and enable personalized management of individual patient needs.",

Patients with PPA carrying GRN mutations (PPA-GRN) were selected among a national prospective research cohort of 1,696 patients with frontotemporal dementia, including 235 patients with PPA. All patients with amyloid-positive CSF biomarkers were excluded. In this cross-sectional study, speech/language and cognitive profiles were characterized with standardized evaluations, and gray matter (GM) atrophy patterns using voxel-based morphometry. Comparisons were performed with controls and patients with sporadic PPA. Among the 235 patients with PPA, 45 (19%) carried GRN mutations, and we studied 32 of these. We showed that logopenic PPA (lvPPA) was the most frequent linguistic variant (n = 13, 41%), followed by nonfluent/agrammatic (nfvPPA; n = 9, 28%) and mixed forms (n = 8, 25%). Semantic variant was rather rare (n = 2, 6%). Patients with lvPPA, qualified as nonamyloid lvPPA, presented canonical logopenic deficit. Seven of 13 had a pure form; 6 showed subtle additional linguistic deficits not fitting criteria for mixed PPA and hence were labeled as logopenic-spectrum variant. GM atrophy involved primarily left posterior temporal gyrus, mirroring neuroanatomic changes of amyloid-positive-lvPPA. Patients with nfvPPA presented agrammatism (89%) rather than apraxia of speech (11%). This study shows that the most frequent PPA variant associated with GRN mutations is nonamyloid lvPPA, preceding nfvPPA and mixed forms, and illustrates that the language network may be affected at different levels. GRN testing is indicated for patients with PPA, whether familial or sporadic. This finding is important for upcoming GRN gene-specific therapies.",

In-depth characterization of the linguistic deficits, and the underlying patterns of grey-matter atrophy in PPA associated with the C9orf72 expansions (PPA-C9orf72) are currently lacking. In this study, we comprehensively analyzed a unique series of 16 patients affected by PPA-C9orf72. Eleven patients were issued from two independent French and Finnish cohorts, and five were identified by means of literature review. Voxel-based morphometry (VBM) studies were performed on three of them. This study depicts the spectrum of C9orf72-related aphasic phenotypes, and illustrates their linguistic presentation. The non-fluent/agrammatic variant was the most frequent phenotype in our series (9/16 patients, 56%), with apraxia of speech being the main defining feature. Left frontal lobe atrophy was present in these subjects, peaking in inferior frontal gyrus. Three patients (19%) showed the semantic variant, with progression of atrophy in temporo-polar regions, later involving orbitofrontal cortex. Anterior temporal lobe dysfunction was also particularly relevant in two patients (12.5%) with mixed forms of PPA. Lastly, two patients (12.5%) had unclassifiable PPA with predominating word-finding difficulties. No PPA-C9orf72 patients in our series fulfilled the criteria of the logopenic variant. Importantly, this study underlines the role of C9orf72 mutation in the disruption of the most anterior parts of the language network, including prefrontal and temporo-polar areas. It provides guidelines for C9orf72 testing in PPA patients, with important clinical impact as gene-specific therapies are upcoming.",

The two variants show some distinct features in the histopathology, localization and prognosis, but to which extent they really differ clinically and pathologically remains to be clarified. Recent neuropathological and neuroimaging studies have suggested a broader spreading of the neurodegenerative process in ALS, extending beyond the motor areas, toward other cortical and deep grey matter regions, many of which are involved in visual processing and saccadic control. Indeed, a wide range of eye movement deficits have been reported in ALS, but they have never been used to distinguish the two ALS variants. Since quantifying eye movements is a very sensitive and specific method for the study of brain networks, we compared different saccadic and visual search behaviours across spinal ALS patients (n = 12), bulbar ALS patients (n = 6) and healthy control subjects (n = 13), along with cognitive and MRI measures, with the aim to define more accurately the two patients subgroups and possibly clarify a different underlying neural impairment. We found separate profiles of visually-guided saccades between spinal (short saccades) and bulbar (slow saccades) ALS, which could result from the pathologic involvement of different pathways. We suggest an early involvement of the parieto-collicular-cerebellar network in spinal ALS and the fronto-brainstem circuit in bulbar ALS. Overall, our data confirm the diagnostic value of the eye movements analysis in ALS and add new insight on the involved neural networks.",
        "36549252": "ID: 36549252\nTitle: Voiceprint and machine learning models for early detection of bulbar dysfunction in ALS.\nAbstract: Bulbar dysfunction is a term used in amyotrophic lateral sclerosis (ALS). It refers to motor neuron disability in the corticobulbar area of the brainstem which leads to a dysfunction of speech and swallowing. One of the earliest symptoms of bulbar dysfunction is voice deterioration characterized by grossly defective articulation, extremely slow laborious speech, marked hypernasality and severe harshness. Recently, research efforts have focused on voice analysis to capture this dysfunction. The main aim of this paper is to provide a new methodology to diagnose this dysfunction automatically at early stages of the disease, earlier than clinicians can do. The study focused on the creation of a voiceprint consisting of a pattern generated from the quasi-periodic components of a steady portion of the five Spanish vowels and the computation of the five principal and independent components of this pattern. Then, a set of statistically significant features was obtained using multivariate analysis of variance and the outcomes of the most common supervised classification models were obtained. The best model (random forest) obtained an accuracy, sensitivity and specificity of 88.3%, 85.0% and 95.0% respectively when classifying bulbar vs. control participants but the results worsened when classifying bulbar vs. no-bulbar patients (accuracy, sensitivity and specificity of 78.7%, 80.0% and 77.5% respectively for support vector machines). Due to the great uncertainty found in the annotated corpus of the ALS patients without bulbar involvement, we used a safe semi-supervised support vector machine to relabel the ALS participants diagnosed without bulbar involvement as bulbar and no-bulbar. The performance of the results obtained increased, especially when classifying bulbar and no-bulbar patients obtaining an accuracy, sensitivity and specificity of 91.0%, 83.3% and 100.0% respectively for support vector machines. This demonstrates that our model can improve the diagnosis of bulbar dysfunction compared not only with clinicians, but also the methods published to date. The results obtained demonstrate the efficiency and applicability of the methodology presented in this paper. It may lead to the development of a cheap and easy-to-use tool to identify this dysfunction in early stages of the disease and monitor progress.",

We therefore sought to examine relationships between maximum anterior isometric lingual pressure (MAIP) with swallowing safety, swallowing efficiency, and swallowing timing metrics in a large cohort of individuals with ALS. Ninety-seven participants with ALS completed a standardized videofluoroscopic swallowing examination (VF) and lingual pressure testing (Iowa Oral Performance Instrument). Duplicate and blinded ratings of the Penetration-Aspiration Scale (PAS) and Analysis of Swallowing Physiology: Events, Kinematics and Timing (ASPEKT) percent efficiency (%C2-C42 ) and timing (laryngeal vestibule closure (LVC) duration: amount of time (milliseconds, msec) between LVC onset and laryngeal vestibule opening; time-to-LVC: hyoid burst to onset of LVC (msec); and swallow reaction time: interval between bolus passing ramus of mandible and onset of LVC (msec)) were performed across bolus trials. Swallowing safety (safe PAS: 1, 2, 4; unsafe PAS: 3, 5, 6, 7, and 8) and efficiency (inefficient: \u22653% worst total residue) were derived. Statistical analyses including descriptives, binary logistic regressions, and Spearman's rho correlations were performed (\u03b1\u00a0=\u00a00.05). Mean MAIP was 36.3\u00a0kPa (SD: 18.7). Mean MAIP was higher in those with safe swallowing as compared to those who penetrated (mean difference: 12\u2009kPa) or aspirated (mean difference: 18\u2009kPa). Individuals with efficient swallowing demonstrated higher MAIP than those with inefficient swallowing (mean difference: 11\u2009kPa). Binary logistic regression analyses revealed increasing MAIP was significantly associated with a 1.06 (95% CI: 1.03-1.09) and 1.04 (95% CI: 1.01-1.06) greater odds of safe and efficient swallowing, respectively. No relationships were observed between MAIP and swallow reaction time across all bolus trials. Longer time-to-LVC (5\u00a0ml thin liquid: rs \u00a0=\u00a0-0.35, p\u00a0=\u00a00.002; cup sip thin liquid: rs \u00a0=\u00a0-0.26, p\u00a0=\u00a00.02; moderately thick liquid: rs \u00a0=\u00a0-0.28, p\u00a0=\u00a00.01) and prolonged LVC duration (cup sip thin liquid, rs \u00a0=\u00a0-0.34, p\u00a0=\u00a00.003) were associated with lower MAIP. Reduced lingual strength was confirmed in this group of 97 individuals with ALS that was associated with a diminished ability to effectively transport boluses and aide in laryngeal vestibule closure to prevent entry of material into the airway.",

We used longitudinal data from two ALS studies where participants recorded their speech on a daily or weekly basis and provided ALSFRS-R speech subscores on a weekly or quarterly basis (quarter-annually). Methods: Using their speech recordings, we measured articulatory precision (a measure of the crispness of pronunciation) using an algorithm that analyzed the acoustic signal of each phoneme in the words produced. First, we established the analytical and clinical validity of the measure of articulatory precision, showing that the measure correlated with perceptual ratings of articulatory precision (r = .9). Second, using articulatory precision from speech samples from each participant collected over a 45-90\u2009day model calibration period, we showed it was possible to predict articulatory precision 30-90 days after the last day of the model calibration period. Finally, we showed that the predicted articulatory precision scores mapped onto ALSFRS-R speech subscores. Results: the mean absolute error was as low as 4% for articulatory precision and 14% for ALSFRS-R speech subscores relative to the total range of their respective scales. Conclusion: Our results demonstrated that a subject-specific prognostic model for speech predicts future articulatory precision and ALSFRS-R speech values accurately.",

Recognition of their distinctive clinical and paraclinical features may help for differential diagnosis. We report 2 cases of atypical trigeminal neuropathy in bulbar-onset IgLON5-D. Trigeminal nerve involvement was assessed using comprehensive clinical, laboratory, electrophysiologic, and MRI workup. Both patients were referred for progressive dysphagia, sialorrhea, and hoarseness. They were treated with bilevel positive airway pressure for nocturnal hypoventilation. Patient 1 complained of continuous facial burning pain with allodynia, exacerbated by mastication and prolonged speech. Patient 2 reported no facial pain. Anti-IgLON5 autoantibodies (IgLON5-Abs) were positive in serum for both patients and CSF for patient 1. Cerebral MRI revealed bilateral T2 fluid-attenuated inversion recovery (FLAIR) hyperintensity and enlargement of trigeminal nerves without gadolinium enhancement in both patients. Needle myography showed fasciculations in masseter muscles. Blink-reflex study confirmed bilateral trigeminal neuropathy only in patient 2. Cortical laser-evoked potentials showed a bilateral small-fiber dysfunction in the trigeminal nerve ophthalmic branch in patient 1. In case of progressive atypical bulbar symptoms, the presence of a trigeminal neuropathy or trigeminal nerve abnormalities on MRI should encourage the testing of IgLON5-Abs in serum and CSF.",

Assessing upper and lower motor neuron impairment in bulbar regions of ALS patients remains challenging, particularly in distinguishing spastic and flaccid dysarthria. This study aimed to evaluate acoustic voice parameters as useful biomarkers to discriminate ALS clinical phenotypes. Triangular vowel space area (tVSA), alternating motion rates (AMRs), and sequential motion rates (SMRs) were analyzed in 36 ALS patients and 20 sex/age-matched healthy controls (HCs). tVSA, AMR, and SMR values significantly differed between ALS and HCs, and between ALS with prevalent upper (pUMN) and lower motor neuron (pLMN) impairment. tVSA showed higher accuracy in discriminating pUMN from pLMN patients. AMR and SMR were significantly lower in patients with bulbar onset than those with spinal onset, both with and without bulbar symptoms. Furthermore, these values were also lower in patients with spinal onset associated with bulbar symptoms than in those with spinal onset alone. Additionally, AMR and SMR values correlated with the degree of dysphagia. Acoustic voice analysis may be considered a useful prognostic tool to differentiate spastic and flaccid dysarthria and to assess the degree of bulbar involvement in ALS.",

Participants engaged in a variety of co-design activities (e.g., designing a website home page and rating self-report assessment features). Workshop transcripts and artefacts (e.g., participants' drawings) were thematically analysed using Gale et al.'s Framework Method in NVivo. Six themes were identified: Interactive; Relatable; Customisable; Intuitive; Inclusive; and Personalised, transparent and trustworthy content.

At diagnosis, up to 25% of people with MND (pwMND) exhibit bulbar dysfunction. Currently, pwMND are assessed using clinical examination and diagnostic tools including the ALS Functional Rating Scale Revised (ALS-FRS(R)), a clinician-administered questionnaire with a single item on speech intelligibility. Here we report on the use of digital technologies to assess speech features as a marker of disease diagnosis and progression in pwMND. Google Scholar, PubMed, Medline and EMBASE were systematically searched. 40 studies were evaluated including 3670 participants; 1878 with a diagnosis of MND. 24 studies used microphones, 5 used smartphones, 6 used apps, 2 used tape recorders and 1 used the Multi-Dimensional Voice Programme (MDVP) to record speech samples. Data extraction and analysis methods varied but included traditional statistical analysis, CSpeech, MATLAB and machine learning (ML) algorithms. Speech features assessed also varied and included jitter, shimmer, fundamental frequency, intelligible speaking rate, pause duration and syllable repetition. Findings from this systematic review indicate that digital speech biomarkers can distinguish pwMND from healthy controls and can help identify bulbar involvement in pwMND. Preliminary evidence suggests digitally assessed acoustic features can identify more nuanced changes in those affected by voice dysfunction. No one digital speech biomarker alone is consistently able to diagnose or prognosticate MND. Further longitudinal studies involving larger samples are required to validate the use of these technologies as diagnostic tools or prognostic biomarkers.",

The aims were to (a) delineate temporal oral DDK deficits relating to the neuromotor pathology of ALS and (b) identify the optimal task-feature combinations to detect speech impairment in ALS. Mandibular myoelectric, kinematic, and acoustic data were acquired from 13 individuals with ALS and 10 healthy controls producing three alternating motion rate tasks and one sequential motion rate task. Twenty-seven features were extracted from the multimodal data, characterizing three temporal constructs: duration/rate, variability, and coordination. The disease impacts on these features were assessed across tasks, and the task eliciting the greatest disease-related change was identified for each feature. Such \"optimal\" task-feature combinations were fed into logistic regression to differentiate individuals with ALS from healthy controls. Temporal deficits in ALS were characterized by (a) increased duration and variability and reduced coordination of jaw muscle activities, (b) increased duration and variability and altered temporal symmetry of jaw velocity profile, (c) increased muscle-burst-to-peak-velocity duration, and (d) increased motion-to-voice onset duration. These temporal features were differentially affected across tasks. The optimal task-feature combinations, which were further clustered into three composite factors reflecting temporal variability, coarser-grained duration, and finer-grained duration, differentiated ALS from controls with an F1 score of 0.86 (precision = 1.00, recall = 0.75). Temporal oral DDK deficits are likely attributed to a hierarchy of interrelated neurophysiological and biomechanical factors associated with the neuromotor pathology of ALS. These deficits, as assessed crossmodally, provide previously unavailable insights into the multifaceted timing impairment of oromotor performance in ALS. The optimal task-feature combinations targeting these deficits show promise as quantitative markers for (early) detection of speech impairment in ALS.",

Automated acoustic assessment of speech in ALS is attractive, and there is a pressing need to validate such tools in line with best practices, including analytical and clinical validation. We hypothesized that data analysis using a novel speech assessment pipeline would correspond strongly to analyses performed using lab-standard practices and that acoustic features from the novel pipeline would correspond to clinical outcomes of interest in ALS. We analyzed data from three standard speech assessment tasks (i.e., vowel phonation, passage reading, and diadochokinesis) in 122 ALS patients. Data were analyzed automatically using a pipeline developed by Winterlight Labs, which yielded 53 acoustic features. First, for analytical validation, data were analyzed using a lab-standard analysis pipeline for comparison. This was followed by univariate analysis (Spearman correlations between individual features in Winterlight and in-lab datasets) and multivariate analysis (sparse canonical correlation analysis (SCCA)). Subsequently, clinical validation was performed. This included univariate analysis (Spearman correlation between automated acoustic features and clinical measures) and multivariate analysis (interpretable autoencoder-based dimensionality reduction). Analytical validity was demonstrated by substantial univariate correlations (Spearman's \u03c1\u2009>\u20090.70) between corresponding pairs of features from automated and lab-based datasets, as well as interpretable SCCA feature groups. Clinical validity was supported by strong univariate correlations between automated features and clinical measures (Spearman's \u03c1\u2009>\u20090.70), as well as associations between multivariate outputs and clinical measures. This novel, automated speech assessment feature set demonstrates substantial promise as a valid tool for analyzing impaired speech in ALS patients and for the further development of these technologies.",

Standard clinical tools for bulbar assessment focus primarily on clinical symptoms and functional outcomes. However, ALS is known to have a long, clinically silent prodromal stage characterized by complex subclinical changes at various levels of the bulbar motor system. These changes accumulate over time and eventually culminate in clinical symptoms and functional declines. Detection of these subclinical changes is critical, both for mechanistic understanding of bulbar neuromuscular pathology and for optimal clinical management of bulbar dysfunction in ALS. To this end, we developed a novel multimodal measurement tool based on two clinically readily available, noninvasive instruments-facial surface electromyography (sEMG) and acoustic techniques-to hierarchically assess seven constructs of bulbar/speech motor control at the neuromuscular and acoustic levels. These constructs, including prosody, pause, functional connectivity, amplitude, rhythm, complexity, and regularity, are both mechanically and clinically relevant to bulbar involvement. Using a custom-developed, fully automated data analytic algorithm, a variety of features were extracted from the sEMG and acoustic recordings of a speech task performed by 13 individuals with ALS and 10 neurologically healthy controls. These features were then factorized into 10 composite outcome measures using confirmatory factor analysis. Statistical and machine learning techniques were applied to these composite outcome measures to evaluate their reliability (internal consistency), validity (concurrent and construct), and efficacy for early detection and progress monitoring of bulbar involvement in ALS. The composite outcome measures were demonstrated to (1) be internally consistent and structurally valid in measuring the targeted constructs; (2) hold concurrent validity with the existing clinical and functional criteria for bulbar assessment; and (3) outperform the outcome measures obtained from each constituent modality in differentiating individuals with ALS from healthy controls. Moreover, the composite outcome measures combined demonstrated high efficacy for detecting subclinical changes in the targeted constructs, both during the prodromal stage and during the transition from prodromal to symptomatic stages. The findings provided compelling initial evidence for the utility of the multimodal measurement tool for improving early detection and progress monitoring of bulbar involvement in ALS, which have important implications in facilitating timely access to and delivery of optimal clinical care of bulbar dysfunction.",

The current gold standard for monitoring ALS progression, the ALS functional rating scale - revised (ALSFRS-R), is based on subjective ratings of symptom severity, and may not capture subtle but clinically meaningful changes due to a lack of granularity. Multimodal speech measures which can be automatically collected from patients in a remote fashion allow us to bridge this gap because they are continuous-valued and therefore, potentially more granular at capturing disease progression. Here we investigate the responsiveness and sensitivity of multimodal speech measures in persons with ALS (pALS) collected via a remote patient monitoring platform in an effort to quantify how long it takes to detect a clinically-meaningful change associated with disease progression. We recorded audio and video from 278 participants and automatically extracted multimodal speech biomarkers (acoustic, orofacial, linguistic) from the data. We find that the timing alignment of pALS speech relative to a canonical elicitation of the same prompt and the number of words used to describe a picture are the most responsive measures at detecting such change in both pALS with bulbar (n = 36) and non-bulbar onset (n = 107). Interestingly, the responsiveness of these measures is stable even at small sample sizes. We further found that certain speech measures are sensitive enough to track bulbar decline even when there is no patient-reported clinical change, i.e. the ALSFRS-R speech score remains unchanged at 3 out of a total possible score of 4. The findings of this study have the potential to facilitate improved, accelerated and cost-effective clinical trials and care.",

Speech and language changes occur in the early stages of FTD and offer a potential non-invasive, early, and accessible diagnostic tool. The use of speech and language markers in this disease spectrum is limited by the fact that most studies investigate English-speaking patients. This systematic review examines the literature on psychoacoustic and linguistic features of speech that occur across the FTD spectrum across as many different languages as possible. 76 papers were identified that investigate psychoacoustic and linguistic markers in discursive speech. 75\u202f% of these papers studied English-speaking patients. The most generalizable features found across different languages, are speech rate, articulation rate, pause frequency, total pause duration, noun-verb ratio, and total number of nouns. While there are clear interlinguistic differences across patient groups, the results show promise for implementation of cross-linguistic markers of speech and language across the FTD spectrum particularly for psychoacoustic features.",

Results from an experimental-clinical study on a completely paralyzed person involved in communication sessions after the implantation of a microelectrode array were retrospectively analyzed. The aim was to focus on the prerequisites and determinants for learning to control a brain-computer interface for communication in paralysis. A comparative examination of the communication results with the current literature was carried out in light of an ideomotor theory of thinking. We speculate that novel skill learning took place and that several aspects of the wording of sentences during the communication sessions reflect preserved cognitive and conscious processing. We also present some speculations on the operant learning procedure used for communication, which argues for the reformulation of the previously postulated hypothesis of the extinction of response planning and goal-directed ideas in the completely locked-in state. We highlight the importance of feedback and reinforcement in the thought-action-consequence associative chain necessary to maintain purposeful communication. Finally, we underline the necessity to consider the psychosocial context of patients and the duration of complete immobilization as determinants of the 'extinction of thinking' theory and to identify the actual barriers preventing communication in these patients.",

Moreover, the emergence of smartphone-based data collection offers a promising approach to reduce frequent hospital visits and enhance patient outcomes. Here, we studied the relationship between bulbar and respiratory functions with voice characteristics of ALS patients, alongside a speech therapist's evaluation, at the convenience of using a simple smartphone. For voice assessment, we considered a speech therapist's standardized tool-consensus auditory-perceptual evaluation of voice (CAPE-V); and an acoustic analysis toolbox. The bulbar sub-score of the revised ALS functional rating scale (ALSFRS-R) was used, and pulmonary function measurements included forced vital capacity (FVC%), maximum expiratory pressure (MEP%), and maximum inspiratory pressure (MIP%). Correlation coefficients and both linear and logistic regression models were applied. A total of 27 ALS patients (12 males; 61 years mean age; 28 months median disease duration) were included. Patients with significant bulbar dysfunction revealed greater CAPE-V scores in overall severity, roughness, strain, pitch, and loudness. They also presented slower speaking rates, longer pauses, and higher jitter values in acoustic analysis (all p < 0.05). The CAPE-V's overall severity and sub-scores for pitch and loudness demonstrated significant correlations with MIP% and MEP% (all p < 0.05). In contrast, acoustic metrics (speaking rate, absolute energy, shimmer, and harmonic-to-noise ratio) significantly correlated with FVC% (all p < 0.05). The results provide supporting evidence for the use of smartphone-based recordings in ALS patients for CAPE-V and acoustic analysis as reliable correlates of bulbar and respiratory function.",

        "39694549": "ID: 39694549\nTitle: [Analysis of clinical characteristics of amyotrophic lateral sclerosis patients initially diagnosed with abnormal laryngeal function].\nAbstract: Objective: To study the laryngeal functional characteristics of patients with amyotrophic lateral sclerosis (ALS)disease diagnosed at the voice clinic. Methods: A retrospective analysis(case series study) was conducted on the laryngeal functional characteristics of 7 patients [2 males, 5 females, age ranged from 43 to 76(60.85\u00b113.18)]with motor neuron disease who visited the voice clinic and were ultimately diagnosed by neurologists. The data included laryngostroboscopy, fiberoptic endoscopic examination of swallowing(FEES), acoustic analysis and laryngeal electromyography(LEMG). Descriptive methods were used for analysis. Results: \u2460There were 2 males and 5 females, with an average age of (60.85\u00b113.18) years. They had previously visited the otolaryngology department more than twice, visit frequency with an average of 3.57 and an average diagnosis time of 12.28 months. The main complaints of the patient at the time of treatment were voice change, dysphagia or vocal fatigue. \u2461LEMG: Among 7 cases, 4 cases demonstrated neurogenic damage, all of which were bilateral, and 3 cases showed normal findings on examination. Spontaneous potentials (SP) were present in three cases for more than 6 months, with the longest duration being 24 months. Three cases exhibited the coexistence of spontaneous potential and reinnervated motor unit potentials (MUPs), and two cases showed bundle tremor potential.\u2462Laryngostroboscopy revealed bilateral vocal fold asymmetry and glottic insufficiency in 7 cases, and decreased vocal cord movement in 4 cases, and vocal cord atrophy in 5 cases. FEES showed that 7 patients presented with mild to severe swallowing dysfunction, 3 cases had soft palate insufficiency and mild to severe food residues in the epiglottic valley and pyriform fossa. 1 case showed leakage and 1 case showed aspiration. Conclusions: Patients presenting with initial symptoms of abnormal laryngeal function should be vigilant for the possibility of motor neuron disease, especially when laryngostroboscopy reveals abnormal vocal fold movement and swallowing dysfunction. LEMG examination reveals bilateral neurogenic damage, prolonged spontaneous potential, coexistence of spontaneous potential and reinnervated MUPs, and the appearance of bundle tremor potential, which is beneficial for early detection of motor neuron disease. \u76ee\u7684\uff1a \u5206\u6790\u9996\u8bca\u55d3\u97f3\u79d1\u7684\u808c\u840e\u7f29\u4fa7\u7d22\u786c\u5316\uff08amyotrophic lateral sclerosis\uff0cALS\uff09\u60a3\u8005\u7684\u5589\u90e8\u75c7\u72b6\u3001\u4f53\u5f81\u548c\u5589\u808c\u7535\u56fe\u7279\u70b9\u3002 \u65b9\u6cd5\uff1a \u8be5\u75c5\u4f8b\u7cfb\u5217\u7814\u7a76\u5206\u67902021\u5e744\u6708\u81f32023\u5e744\u6708\u5728\u53a6\u95e8\u5927\u5b66\u9644\u5c5e\u4e2d\u5c71\u533b\u9662\u55d3\u97f3\u95e8\u8bca\u9996\u8bca\u3001\u6700\u7ec8\u786e\u8bcaALS\u76847\u4f8b\u60a3\u8005\uff3b\u7537\u60272\u4f8b\uff0c\u5973\u60275\u4f8b\uff1b\u5e74\u9f84\u4e3a43~76\uff0860.85\u00b113.18\uff09\u5c81\uff3d\u7684\u5589\u90e8\u75c7\u72b6\u3001\u4f53\u5f81\uff08\u9891\u95ea\u5589\u955c\u3001\u541e\u54bd\u5589\u955c\uff09\u3001\u58f0\u5b66\u8bc4\u4f30\u53ca\u5589\u808c\u7535\u56fe\u8d44\u6599\u3002\u91c7\u7528\u63cf\u8ff0\u6027\u65b9\u6cd5\u8fdb\u884c\u5206\u6790\u3002 \u7ed3\u679c\uff1a \u24607\u4f8b\u60a3\u8005\u65e2\u5f80\u5747\u5728\u8033\u9f3b\u54bd\u5589\u79d1\u5c31\u8bca2\u6b21\u4ee5\u4e0a\uff08\u4e2d\u4f4d\u6b21\u65703.57\u6b21\uff09\uff0c\u786e\u8bca\u65f6\u95f4\u4e3a12.28\u4e2a\u6708\u3002\u5c31\u8bca\u65f6\u4e3b\u8bc9\u4e3b\u8981\u4e3a\uff1a\u58f0\u97f3\u5636\u54d1\u3001\u53d1\u58f0\u8d39\u529b\u3001\u53d1\u58f0\u75b2\u52b3\u3001\u541e\u54bd\u5f02\u7269\u611f\u6216\u541e\u54bd\u56f0\u96be\u3001\u547c\u5438\u4e0d\u7545\u53ca\u8bf4\u8bdd\u542b\u7cca\u7b49\u3002\u2461\u5589\u808c\u7535\u56fe\uff1a7\u4f8b\u4e2d4\u4f8b\u63d0\u793a\u4e3a\u795e\u7ecf\u6e90\u6027\u635f\u5bb3\uff0c\u4e14\u5747\u4e3a\u53cc\u4fa7\uff0c3\u4f8b\u68c0\u67e5\u6b63\u5e38\uff1b3\u4f8b\u53d1\u73b0\u81ea\u53d1\u7535\u4f4d\u8005\u5747\u51fa\u73b0\u57286\u4e2a\u6708\u4ee5\u4e0a\uff0c\u6700\u957f\u8005\u8fbe24\u4e2a\u6708\uff1b3\u4f8b\u53d1\u73b0\u8fdb\u884c\u6027\u5931\u795e\u7ecf\u635f\u5bb3\u548c\u6162\u6027\u518d\u751f\u5e76\u5b58\uff0c2\u4f8b\u51fa\u73b0\u675f\u98a4\u7535\u4f4d\u3002\u2462\u9891\u95ea\u5589\u955c\uff1a7\u4f8b\u60a3\u8005\u5747\u51fa\u73b0\u53cc\u4fa7\u58f0\u5e26\u8fd0\u52a8\u4e0d\u5bf9\u79f0\u548c\u58f0\u95e8\u95ed\u5408\u4e0d\u5168\uff084\u4f8b\u5782\u76f4\u9762\uff0c3\u4f8b\u6c34\u5e73\u9762\uff09\uff0c5\u4f8b\u58f0\u5e26\u677e\u5f1b\uff0c3\u4f8b\u53cc\u4fa7\u58f0\u5e26\u8fd0\u52a8\u51cf\u5f31\uff0c1\u4f8b\u5355\u4fa7\u58f0\u5e26\u8fd0\u52a8\u51cf\u5f31\u3002\u541e\u54bd\u5589\u955c\uff1a7\u4f8b\u60a3\u8005\u5747\u663e\u793a\u6709\u8f7b-\u91cd\u5ea6\u4e0d\u7b49\u7684\u541e\u54bd\u529f\u80fd\u969c\u788d\uff0c3\u4f8b\u60a3\u8005\u8f6f\u816d\u95ed\u5408\u4e0d\u5168\uff0c\u8fdb\u98df\u540e\u4f1a\u538c\u8c37\u53ca\u68a8\u72b6\u7a9d\u5747\u6709\u8f7b\u5ea6-\u91cd\u5ea6\u4e0d\u7b49\u7684\u98df\u7269\u6b8b\u7559\uff0c1\u4f8b\u89c1\u6e17\u6f0f\uff0c1\u4f8b\u89c1\u8bef\u5438\u3002 \u7ed3\u8bba\uff1a \u9996\u53d1\u75c7\u72b6\u4e3a\u5589\u529f\u80fd\u5f02\u5e38\u7684\u60a3\u8005\uff0c\u5f53\u9891\u95ea\u5589\u955c\u53d1\u73b0\u58f0\u5e26\u8fd0\u52a8\u529f\u80fd\u5f02\u5e38\u7279\u522b\u662f\u58f0\u95e8\u95ed\u5408\u4e0d\u5168\u540c\u65f6\u4f34\u6709\u541e\u54bd\u5589\u955c\u4e0b\u541e\u54bd\u529f\u80fd\u5f02\u5e38\u65f6\uff0c\u9700\u8b66\u60d5ALS\u7684\u53ef\u80fd\uff0c\u5589\u808c\u7535\u56fe\u68c0\u67e5\u53d1\u73b0\u53cc\u4fa7\u795e\u7ecf\u6e90\u6027\u635f\u5bb3\u3001\u81ea\u53d1\u7535\u4f4d\u957f\u65f6\u95f4\u6301\u7eed\u5b58\u5728\u3001\u81ea\u53d1\u7535\u4f4d\u548c\u5bbd\u5927\u8fd0\u52a8\u5355\u4f4d\u7535\u4f4d\uff08motor unit potential\uff0cMUP\uff09\u5e76\u5b58\u4ee5\u53ca\u675f\u98a4\u7535\u4f4d\u7684\u51fa\u73b0\uff0c\u6709\u52a9\u4e8e\u65e9\u671f\u53d1\u73b0\u8bca\u65adALS\u3002.",
        "39779800": "ID: 39779800\nTitle: Artificial intelligence empowered voice generation for amyotrophic lateral sclerosis patients.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease that can result in a progressive loss of speech due to bulbar dysfunction, which can have significant negative impact on the patient's mental well-being. Alternative Augmentative Communication (AAC) strategies based on synthetic voices have been shown to assist patients in maintaining communication and improving their Quality of Life (QoL). However, such synthetic voices are often perceived as impersonal and fail to capture the unique voice and identity of the patient. To tackle this issue, combining voice banking (VB) and artificial intelligence (AI) has emerged as a more natural communication strategy, enabling individuals to preserve their voice for use with AAC devices as needed. This involves recording speech samples to generate a synthetic voice closely resembling the individual's own. Despite the increasing interest in VB, there's a lack of clear strategies for its effective implementation in rapidly progressing diseases like ALS. Additionally, the perceptual quality of VB on patients with preserved speech, especially when offered early in the disease, remains poorly understood. In light of these challenges, this study aims to assess the effectiveness and the perceptual impact of AI-generated voices on ALS patients with preserved speech, utilizing a personalized voice synthesis system based on machine learning. The AI-generated patient-specific voice is achieved through voice recording, followed by fine-tuning using a Generative Adversarial Network for Efficient and High Fidelity Speech Synthesis (HiFi-GAN), resulting in a model capable of producing speech highly similar to the patient's own voice, with exceptional expressive and audio quality. By addressing these aspects, this study intends to offer valuable insights into the potential benefits and challenges of combining VB with AI voices to enhance communication support for ALS patients.",

For the T9 PM, both upper limit for mean and individual mean consecutive difference (MCD) values and spike numbers were calculated according to jitter values of pairs from controls. In addition to the descriptive statistics, differences between two groups and T9 PM needle EMG and jitter analysis findings of patients were compared (p\u00a0=\u00a00.05). Mean MCD median values of T9 PM were 62.8 and 26.2\u00a0\u00b5s in patient and controls respectively. Upper limit of mean and individual MCDs for the T9 PM were determined as 36.95\u00a0\u03bcs, 57.95\u00a0\u03bcs respectively. The differences between controls and patients in terms of all jitter analysis parametres (p\u00a0<\u00a00.001) and the comparison of patients' T9 PM needle EMG and jitter analysis findings grading were statistically significant (p\u00a0=\u00a00.029). The T9 PM jitter analysis performed during routine EMG can be used to support the electrophysiological diagnosis of ALS in challenging cases and may contribute to minimizing the number of muscles examined. Furthermore, our study contributed to the T9 PM reference values for jitter analysis.",

A validated objective marker is however lacking to characterize and phenotype bulbar involvement, positing a major barrier to early detection, progress monitoring, and tailored care. This study aimed to bridge this gap by constructing a multiplex functional mandibular muscle network to provide a novel objective measurement tool of bulbar involvement. A noninvasive electrophysiological technique-surface electromyography-was combined with graph network analysis to extract 48 features measuring the regulatory mechanisms, connectivity, integration, segregation, assortativity, and lateralization of the functional muscle network during a speech task. These features were clustered into 10 interpretable latent factors. To evaluate the utility of the muscle network as a bulbar measurement tool, a heterogenous ALS cohort, consisting of eight individuals with overt clinical bulbar symptoms and seven without, along with 10 neurologically healthy controls, was employed to train and validate statistical and machine learning algorithms to assess the disease effects on the network features and the relation of the network performance to the current clinical diagnostic standard and behavioral patterns of bulbar involvement. Significant disease effects were found on most network features. The most robust effects were manifested by reduced and more variable myoelectric activities, and reduced functional connectivity and integration of the muscle network. The 10 latent factors (1) demonstrated acceptably high efficacy for detecting bulbar neuromuscular changes across all clinically confirmed symptomatic cases and clinically silent prodromal cases (area under the curve = 0.89-0.91; F1 score = 0.85-0.87; precision = 0.84-0.86; recall = 0.87-0.88); and (2) selectively correlated with clinically meaningful behavioral patterns (conditional R 2 = 0.45-0.81). The functional muscle network shows promise for an objective quantifiable measurement tool to improve early detection and profiling of bulbar involvement across the prodromal and symptomatic stages. This tool has various strengths, including the use of a clinically readily available noninvasive instrument, fully automated data processing and analytics, and generation of interpretable objective outcome measures (i.e., latent factors), together rendering it highly scalable in routine clinical practice for assessing and monitoring of bulbar involvement.",

However, interventions that focus on improving speech may not be able to counteract decline as the disease progresses. Researchers have suggested interventions that help PALS's communication partners tune their speech perception systems to PALS's production. In the current study, we take a first step to establishing the need and enthusiasm for such interventions on the part of PALS and their caregivers (CPALS). PALS and CPALS recruited from the Greater Philadelphia chapter of the ALS association completed novel questionnaires probing their everyday speech communication and speech intervention experiences. Questions focused especially on changes in communication partners' ability to understand PALS' speech. Both quantitative and qualitative data were recorded. PALS (n\u2009=\u200921) and CPALS (n\u2009=\u200922) reported speech as a primary mode of communication despite declines in intelligibility. However, most also indicated variability in PALS's speech intelligibility depending on the communication partner, indicating that frequent communication partners were better able to understand PALS's speech. Both groups reported interest in interventions supporting speech intelligibility and were most interested in speech interventions that included PALS and CPALS together. PALS and especially CPALS in our study expressed interest in speech interventions that involved both parties. Thus, there is both a need for and a desire in the community for interactive speech interventions that support intelligibility. Additionally, our findings lend support to clinical approaches targeting frequent communication partners in addition to PALS.",

Limited research exists on the factors contributing to dysphagia-related burden, particularly across disease trajectories. This study aimed to (a) determine if dysphagia-related burden predicts general caregiver burden, (b) identify predictors of dysphagia-related burden, and (c) examine relationships between dysphagia severity, disease severity, and dysphagia-related burden. Care partners (N = 211; 80% female; Mage = 60 \u00b1 14 years) from clinics in Canada, New Zealand, and the United States participated. Care recipients included those with amyotrophic lateral sclerosis (ALS; n = 48), dementia (n = 110), and Parkinson's disease (PD; n = 53). General burden was measured using the Zarit Burden Interview, while dysphagia-related burden was assessed via the Caregiver Assessment of Reported Experiences with Swallowing Difficulties. Multiple regression analyses examined predictors of general and dysphagia-related burden and their relationships to dysphagia and disease severity. Higher general burden was associated with female caregivers (\u03b2 = -.19, p = .05), higher education (\u03b2 = .16, p = .03), caring for someone with dementia (\u03b2 = .36, p = .01), and greater dysphagia-related burden (\u03b2 = .33, p = .01). Predictors of dysphagia-related burden included working caregivers (\u03b2 = .15, p = .01), increased dysphagia symptoms (\u03b2 = .77, p < .01), and caring for individuals with ALS or dementia (vs. PD; \u03b2 = -.16, p = .02). Dysphagia burden varied by disease severity and diet tolerance (p < .01). Managing dysphagia independently contributes to caregiver burden, potentially increasing burnout and nonadherence to clinical recommendations. Early, proactive inquiry about dysphagia-related care partner burden and provision of support to minimize burden should be considered early in disease management. https://doi.org/10.23641/asha.28843055.",

Two targeted literature reviews were conducted to identify and describe key concepts potentially important to patients (signs, symptoms, impacts), and identify commonly used COAs in ALS. Insights gained were used to map target COAs to concepts identified as potentially relevant to patients and their caregivers. COAs of interest were further examined to evaluate evidence of their validity and reliability within ALS. Forty-three articles were identified for concept extraction. Signs and symptoms were identified across multiple themes: motor; non-motor; respiratory; cognitive; and behavioral. Patient impacts were identified across multiple themes: physical; functional; emotional; social; and other aspects of well-being. Caregiver impacts were identified across four themes: general; emotional; social; and physical. Of 236 unique COAs identified, 6 were found to provide the greatest coverage of potentially important concepts. Closer examination of these showed some evidence gaps supporting content validity and/or psychometric properties. Several concepts related to ALS were identified that are relevant to patients in their daily lives. We identified and reviewed COAs commonly used in assessing these concepts, and found gaps in their content validity and/or psychometric properties. These findings suggest the need for further testing/refinement of existing tools, and the opportunity to use other instruments alongside those most frequently used (e.g., ALSFRS-R) to comprehensively capture the patient experience of ALS in future clinical trial and real-world studies.",
        "40407667": "ID: 40407667\nTitle: Relationship Between Voice Analysis and Functional Status in Patients with Amyotrophic Lateral Sclerosis.\nAbstract: Background: Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease affecting both upper and lower motor neurons, with bulbar dysfunction manifesting in up to 80% of patients. Dysarthria, characterized by impaired speech production, is common in ALS and often correlates with disease severity. Voice analysis has emerged as a promising tool for detecting disease progression and monitoring functional status. Methods: This study investigates acoustic and biomechanical voice alterations in ALS patients and their association with clinical measures of functional independence. A descriptive observational case series study was conducted, involving 43 ALS patients and 43 age and sex matched controls with non-neurological voice disorders. Sustained vowel /a/ recordings were obtained and analyzed using Voice Clinical Systems\u00ae and Praat software (version 6.2.22). Biomechanical and acoustic parameters were correlated with ALS Functional Rating Scale-Revised (ALSFRS-R) and Barthel Index scores. Results: Significant differences were observed between ALS and control groups (elevated muscle force and tension and interedge distance in non-ALS individuals). Between bulbar and spinal ALS subtypes, elevated values were observed in certain parameters in Bulbar ALS patients, indicating irregular vocal fold contact and weakened phonatory control, while spinal ALS exhibited increased values, suggesting higher phonatory muscle tension. Elevated biomechanical parameters were significantly correlated with low ALSFRS-R scores, suggesting a possible relationship between voice measures and functional decline. However, acoustic measurements showed no relationship with performance status. Conclusions: These results highlight the potential of voice analysis as a non-invasive, objective tool for monitoring ALS stage and differentiating between subtypes. Further research is needed to validate these findings and explore their clinical applications.",

Data from 16 individuals with primary lateral sclerosis (PLS) representing UMN disease, 14 individuals with spinal and bulbar muscular atrophy (SBMA) representing LMN disease, and 25 neurologically healthy individuals were analyzed. Clinical measures were also collected from PLS and SBMA groups. All participants were remotely recorded performing passage reading, rapid syllable repetition, and vowel phonation. Fifty-two acoustic features were extracted representing articulation, phonation, prosody, resonance, and overall speech timing. Features were compared using Kruskal-Wallis tests for between-group comparisons and Spearman correlations between acoustic features and clinical scores. Articulatory and prosodic features best differentiated PLS, SBMA and controls. Correlations were observed in the PLS group between the clinical score and various articulatory features, most notably those indexing tongue and jaw movements. Our study demonstrated that acoustic assessment could capture fingerprints of dysarthrias associated with PLS and SBMA. These findings also demonstrate the potential for remote speech assessment to characterize diverse dysarthria profiles and pave the way for creating ways for personalized disease management approaches in clinical care and trials.",

This study aimed to evaluate the construct validity of the ALSBDI-R by examining its correlation with established clinical measures and its ability to discriminate among different bulbar disease severities. A total of 92 patients with ALS were recruited from two multidisciplinary clinics. Participants were assessed using the ALSBDI-R, the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R), the Center for Neurologic Study Bulbar Function Scale (CNS-BFS), the Sentence Intelligibility Test, and the Eating Assessment Tool (EAT-10). Construct validity was established through Spearman correlations and comparison of ALSBDI-R scores across bulbar severity groups (asymptomatic, mild, moderate, severe). Strong correlations were found between ALSBDI-R total scores and bulbar-specific measures such as ALSFRS-R bulbar subscore (r = -.85), CNS-BFS (r = .85), and EAT-10 (r = .77). The ALSBDI-R effectively discriminated between severity groups, supporting its construct validity. Severity bins were created based on median ALSBDI-R total scores for each group. The ALSBDI-R is a valid tool for remotely assessing bulbar dysfunction in patients with ALS. Despite several limitations, its ability to capture varying degrees of severity makes it valuable for clinical use and research, offering a standardized approach to monitor disease progression remotely.",

BCIs have been used to translate the neural correlates of attempted speech into text1-3. However, text communication fails to capture the nuances of human speech, such as prosody and immediately hearing one's own voice. Here we demonstrate a brain-to-voice neuroprosthesis that instantaneously synthesizes voice with closed-loop audio feedback by decoding neural activity from 256 microelectrodes implanted into the ventral precentral gyrus of a man with amyotrophic lateral sclerosis and severe dysarthria. We overcame the challenge of lacking ground-truth speech for training the neural decoder and were able to accurately synthesize his voice. Along with phonemic content, we were also able to decode paralinguistic features from intracortical activity, enabling the participant to modulate his BCI-synthesized voice in real time to change intonation and sing short melodies. These results demonstrate the feasibility of enabling people with paralysis to speak intelligibly and expressively through a BCI.",

In the United States, Spanish-English bilingual speakers are the largest bilingual group. Yet, the potential effect of being bilingual, specifically a Spanish-English speaker, on voice quality is poorly understood. The current study consequently set out to systematically review the literature on the association between being a Spanish-English bilingual speaker and voice quality. Systematic review. A systematic review of association was conducted using Moola et al's guidelines. A search string was developed and run in May 2024 across three databases: MEDLINE (via PubMed), CINAHL via EBSCOhost, and Scopus. After duplicate removal, title, and abstract screening, full-text screening was performed, and peer-reviewed articles considering voice quality measures in Spanish-English bilingual speakers were included. Data were extracted and presented in table format, and the quality of the articles was assessed using the Checklist for Analytical Cross-Sectional Studies. In total, 685 records were retrieved, with 485 remaining after duplicate removal. After title and abstract screening, 25 full texts were screened, including 8 articles in the review. Five studies included acoustic measures describing voice quality, with only three including auditory-perceptual analysis. The most commonly considered vocal trait in Spanish-English bilinguals was vocal fry, with the included studies pointing to increased vocal fry use when speaking English. Only a few articles discuss potential vocal changes in Spanish-English bilinguals. Further research is needed to elucidate any potential vocal changes related to being a bilingual speaker, as the current small number of studies and mixed findings make drawing conclusions difficult. More standardization across voice and language assessment could be beneficial.",

We describe three cases of PAOS with underlying Pick's disease, a 3-repeat tauopathy, who lacked CBS or PSP features during life. We reviewed patients enrolled in the Neurodegenerative Research Group's ongoing studies on speech and language disorders and identified those with PAOS who had autopsy-confirmed Pick's disease. All patients had comprehensive neurologic, speech-language, and neuropsychological assessments, as well as multimodal neuroimaging, during life. Three female patients presented with phonetic PAOS without parkinsonism. Patient 1 had speech onset at age 54, later developed behavioral variant frontotemporal dementia (bvFTD), and died at 64. Patient 2 had speech onset at 47, early bvFTD features, prominent frontal and temporal involvement, and died at 53. Patient 3 had speech onset at 58, minimal behavioral changes, primarily frontal involvement on imaging, and died at 63. Our findings highlight that Pick's disease can present with PAOS and may be distinguished from 4R-tau PAOS by an absence of motoric CBS/PSP features and, in some cases, by prominent temporal hypometabolism with bvFTD development. These atypical features may prove useful in the antemortem identification of Pick's disease as a cause of PAOS.",

Bulbar-onset ALS is a distinct clinical subtype, with initial involvement of bulbar motor neurons, often causing severe speech and swallowing difficulties. Despite its impact, bulbar-onset ALS, especially with rare symptoms like unilateral vocal cord palsy (UVCP), lacks extensive research. Here, we detail the case of a 79-year-old nonambulatory diabetic male with a 1-year history of hoarseness of voice, diagnosed with bulbar-onset ALS with UVCP. This underscores the importance of recognizing unusual presentations of ALS, particularly in geriatric populations, urging tailored medical evaluations for optimal care and improved outcomes in this challenging neurological condition.",

In Cyprus, barriers such as long waiting lists, financial constraints, and limited public awareness restrict access to SLT services. University-led clinics offer a promising alternative by providing affordable, accessible care while training future clinicians. This study aimed to examine the demographic profiles, referral pathways, and diagnostic patterns of children accessing services at a university-led SLT clinic. By documenting referral trends and diagnostic outcomes, this study offers preliminary insights into patterns of service use and potential access disparities in the Cypriot context. Methods: A retrospective analysis was conducted using records from 235 children, aged 0;7 to 15 years, assessed at the University Rehabilitation Clinic between 2015 and 2024. Data included age, gender, socioeconomic status (SES), bilingualism, referral source, and diagnostic outcomes. Diagnoses were classified using Bishop et al.'s (2016) framework. Results: Significant associations were identified between age, parental education, referral source, and diagnostic category. Older children (9;1-12 years) demonstrated a markedly increased likelihood of receiving a developmental language disorder (DLD) diagnosis. Higher parental education levels and referrals from teachers or parents were also predictive of DLD and other communication impairments. Bilingualism was not a significant predictor of diagnostic category. Conclusions: The findings suggest that university-led clinics may serve as an important access point for underserved populations in Cyprus. This study provides preliminary evidence concerning demographic and referral factors that can inform outreach strategies and future service planning.",

In this case, a 60-year-old female presented with progressive choking episodes and speech slurring over 9 months, exhibiting dysarthria, prominent tongue atrophy, fasciculations, and hyperreflexia. Needle electromyography (EMG) showed diffuse chronic neurogenic changes with signs of active denervation changes prominent on the tongue and right arm with normal sensory nerve studies. Magnetic resonance imaging (MRI) brain imaging revealed a Diffuse T1 Weighted image (T1WI) hyperintense of tongue known as \"bright tongue sign\" indicating fatty infiltration of tongue muscles, consistent with neurogenic atrophy. This case underscores the importance of recognizing this characteristic tongue hyperintensity as a valuable radiological clue in diagnosing bulbar-onset ALS and highlights the potential for early diagnosis to improve patient management and outcomes.",

This study examined how different methodological choices affect MDC thresholds of speech intelligibility in speakers with dysarthria. The goals of this study were to compare MDCs calculated using (a) three different reliability methods, (b) two different reliability statistics, and (c) three different SEM calculations. Recordings of the Speech Intelligibility Test from 200 speakers including speakers with amyotrophic lateral sclerosis (n = 16), Huntington's disease (n = 44), multiple sclerosis (n = 60), and Parkinson's disease (n = 40), along with healthy controls (n = 40), were drawn from two databases. Thirty inexperienced listeners completed two sessions, providing orthographic transcriptions of 20 speakers. MDCs of intelligibility were calculated using (a) three reliability methods (i.e., test-retest, split-half, and intrarater), (b) two reliability statistics (i.e., Pearson r and intraclass correlation coefficients [ICCs]), and (c) three different formulas for calculating the SEM. Kruskal-Wallis tests were used to assess the effects of reliability methods, statistics, and SEM calculations. Significant differences were found between the MDCs when using split-half and test-retest reliability, when using Pearson r and ICC, and when using two of the three SEM calculations. Results demonstrate that methodological decisions can impact MDCs of speech intelligibility in speakers with dysarthria, highlighting the need for specific, detailed reporting of methodology used to calculate MDCs in future work. Findings can provide methodological guidance for future studies and contextualize existing research on intelligibility changes.",

One of the hallmarks of ALS, especially its bulbar form, is dysarthria, which significantly impairs the quality of life of ALS patients. This review provides a comprehensive overview of the current knowledge on the clinical manifestations, diagnostic differentiation, underlying mechanisms, diagnostic tools, and therapeutic strategies for the treatment of dysarthria in ALS. We update on the most promising digital speech biomarkers of ALS that are critical for early and differential diagnosis. Advances in artificial intelligence and digital speech processing have transformed the analysis of speech patterns, and offer the opportunity to start therapy early to improve vocal function, as speech rate appears to decline significantly before the diagnosis of ALS is confirmed. In addition, we discuss the impact of interventions that can improve vocal function and quality of life for patients, such as compensatory speech techniques, surgical options, improving lung function and respiratory muscle strength, and percutaneous dilated tracheostomy, possibly with adjunctive therapies to treat respiratory insufficiency, and finally assistive devices for alternative communication.",

A bibliometric analysis was performed on journal articles about voice disorders and acoustic voice assessment in English, Spanish, and Portuguese using seven indexed databases. The analyzed bibliometric parameters included publication year, authors, institutions, countries, journals, subject areas, and keywords. VOSviewer software was used for keyword co-occurrence analysis and authorships network analysis. The initial search yielded 6532 publications, with 1253 relevant papers after screening (1951-2024). Publications in acoustic voice assessment had 74 years of exponential growth (25 % published after 2021). The publishing journals covered 80 categories and subjects. Artificial Intelligence, though recent, was among the top journal subjects. Health conditions like dementia, Alzheimer's, Amyotrophic lateral sclerosis, and depression were underassessed compared to Parkinson's. The literature focused on four separate themes: physiology of voice-affecting conditions; speech acoustics for evaluating dysphonia; speech production measurements for treating voice disorders; machine learning integration for voice disorder assessment. Taking a wide view of acoustic voice assessment demonstrated research strengths and gaps-highlighting where it is used and not used-and the co-occurrence of various voice assessment topics.

Quantitative motor speech analysis can identify features of dysarthria that worsen with ALS progression but are not, inherently, clinically meaningful. Listener effort (LE) is a clinician-rated feature describing how much effort the listener needs to exert to understand the dysarthric speaker. This study investigated whether LE could act as a clinically meaningful measure of ALS dysarthria that could be used as an outcome measure in clinical trials. The Everything ALS Speech Study obtained longitudinal clinical information and speech recordings from 292 participants. In a subset of 125 participants, we measured speaking rate and three speech-language pathologists (SLPs) with expertise in ALS rated LE. We also built and tested a LE prediction algorithm to predict the SLPs' rating of LE. In addition, all speech recordings and associated clinical data are now being made available to ALS researchers via the Everything ALS portal. LE intra- and inter-rater reliability was very high (ICC 0.94-0.95). LE correlated with other measures of dysarthria at baseline and changed over time in participants with ALS (slope 0.77 pts/month, SE = 0.15, P < 0.001) but not controls (slope 0.005 pts/month, SE = 0.02, P = 0.807). The slope of LE progression was faster in people with bulbar onset than non-bulbar onset ALS (1.66 points/month versus 0.42 pts/month; P < 0.001) but was similar in all participants who had bulbar dysfunction at baseline, regardless of ALS site of onset (1.52 pts/month for bulbar onset versus 0.98 pts/month for non-bulbar onset with current bulbar involvement; P = 0.36). The LE prediction model predicted the true LE, with an average R 2 of 0.83 \u00b1 0.07. Dysarthria is associated with decreased quality of life in people with ALS. Quantitative measures of dysarthria in ALS could be useful as ALS clinical trial outcome measures, providing insight into the progression of bulbar symptoms. Speaking rate quantifies progression but is variable across speaking stimuli, emotional states and contextual factors. LE is more inherently clinically meaningful, can be measured reliably by SLPs, changes quantitatively over time and is highly reproducible, thus may be useful as a clinical outcome assessment for ALS clinical trials. Furthermore, a LE prediction model is effective at predicting LE scores and should be validated on an external dataset.",

We introduce a new semi-automated method, enabled by a manually curated dataset of MRI scans to accurately measure five key tongue muscles, combining AI-assisted, atlas-based, and manual segmentation approaches. The method was tested and validated in a dataset of 178 scans and included segmentation validation (n\u00a0=\u00a0103) and clinical application (n\u00a0=\u00a0132) in individuals with motor neuron disease. We show that people with speech and swallowing deficits tend to have smaller muscle volumes and present a normalisation strategy that removes confounding demographic factors, enabling broader application to large MRI datasets. As the tongue is generally covered in neuroimaging protocols, our multi-contrast pipeline will allow for the post-hoc analysis of a vast number of datasets. We expect this work to enable the investigation of tongue muscle morphology as a marker in a wide range of diseases that implicate tongue function, including neurodegenerative diseases and pathological speech disorders.",

OFELIA (NCT05073133) is a phase 4, 18-month, open-label, multicenter, non-randomised study (Brazil, Argentina) of onasemnogene abeparvovec treatment (1\u00b71 \u00d7 1014 vg/kg) for symptomatic patients with SMA \u226424 months of age and \u226417 kg (grouped by age [0-12 vs >12-24 months] and weight [<8\u00b75 kg vs \u22658\u00b75 kg]). The primary endpoint was safety. The secondary endpoint was demonstration of motor milestones measured at screening and at 6, 12, and 18 months post-onasemnogene abeparvovec infusion, according to the World Health Organization Multicentre Growth Reference Study criteria. Sixteen patients were enrolled (n = 11/16 female; n = 10/16 SMA type 1) (n = 17 screened). All reported adverse events (AEs). Eleven reported serious AEs; 12 reported an AE of special interest, most commonly hepatotoxicity (asymptomatic) (n = 11/12), thrombocytopenia (n = 5/12), and thrombotic microangiopathy (n = 2/12). Two deaths occurred: one possibly related to treatment (AST >20 \u00d7 upper limit of normal, sepsis, infection, multiorgan failure, thrombotic microangiopathy) and one due to respiratory infection. Most patients maintained/improved motor milestones up to 18 months post-onasemnogene abeparvovec (e.g., sitting, crawling, standing, walking), including those in the >12-24-month age group. Most common AEs of special interest were hepatotoxicity, thrombocytopenia, and thrombotic microangiopathy; incidence rates (hepatotoxicity, thrombocytopenia) were similar compared with studies in patients >6 months of age and >8\u00b75 kg. Efficacy data on demonstration of motor milestones suggest that Latin American patients with SMA may benefit from onasemnogene abeparvovec treatment.

This paper discusses the use of acoustic analysis of sustained vowel phonations (SVP) and machine learning in ALS detection. An SVP corpus of 128 (64 /a/ and 64 /i/) from 31 patients with ALS and 33 healthy controls (HC) was employed. 131 acoustic features, including jitter, shimmer, Mel-Frequency Cepstral Coefficients (MFCCs), and Pathological Vibrato Index (PVI), were extracted. A LightGBM (Light Gradient Boosting Machine)-based model was built and optimized using 5-fold cross-validation to separate ALS cases. Model performance and feature importance were evaluated. The model performed well with high predictability, yielding an RMSLE of 0.162 and most predictions closely correlating with actual diagnoses. The top features obtained were S55_i, CCI(2), and dCCa(12), which were consistently at the top of the ranking list, indicating their role in ALS detection. The PVI was determined to be a significant biomarker with high values having high correlations with ALS diagnoses. But the multimodal nature of the predictive values indicated some flaws in generalization. This paper demonstrates the applicability of acoustic analysis and machine learning for early ALS detection. The proposed method provides an affordable, low-cost, and non-invasive way for ALS diagnosis with potential for application in telemedicine and clinical settings. Future research must expand datasets and integrate additional diagnostic modalities to improve the model's robustness and clinical translation.",

Speech intelligibility is a crucial component of communication affected in ALS, requiring objective, scalable assessment methods as an indicator of disease progression and treatment efficacy. Objective: This study investigates whether speech and bulbar function in ALS could be evaluated and monitored utilizing an automated digital measure of speech intelligibility derived from naturalistic picture descriptions. Methods: Speech recordings from 44 patients living with ALS (plwALS) and 49 matched healthy controls (HC) were analyzed and processed utilizing an automated speech analysis pipeline to extract an intelligibility score. These were part of a cross-sectional and longitudinal study involving two assessments.\u00a0Results: The findings confirmed that speech intelligibility is significantly reduced in plwALS compared to HC. Those with bulbar-onset ALS have lower intelligibility than those with spinal-onset ALS, and the intelligibility of individuals with bulbar symptoms-regardless of the onset type-is lower than in plwALS without bulbar symptoms. Declining ALS-related speech scores correspond with worsening intelligibility in longitudinal assessments. Intelligibility correlates strongly with bulbar-specific clinical measures but not with global scores, highlighting its role in tracking bulbar progression. In some plwALS, we were able to demonstrate that automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring. Conclusion: Our findings highlight that automated speech intelligibility assessments can be a valuable marker to improve clinical monitoring and facilitate earlier intervention in ALS as a supplement to standard assessments.",

Scalable digital health tools and machine learning (ML) are essential for diagnosing and tracking neurodegenerative disease. A total of 92 individuals were included in this study (21 PSP, 21 PD, 18 HD, 15 ALS, and 16 healthy elderly controls (CTR)). The Rainbow Passage was collected on a digital device and analyzed to extract 12 speech features representing speech production. A set of Elastic Net ML models was trained on these speech features to differentiate between diagnostic classes. A specialized Support Vector Machine ML model was then developed to differentiate PSP from PD. Elastic Net models achieved a balanced accuracy of 77% over 5 diagnostic classes (group-specific sensitivities of 76% for PSP, 67% for PD, 83% for HD, 73% for ALS, and 88% for CTR) and 83% over 4 diagnostic classes (group-specific sensitivities of 83% for PSP-PD, 83% for HD, 73% for ALS, and 94% for CTR). The PSP vs. PD classification model demonstrated a balanced accuracy of 85%, with sensitivity of 88% for PSP and 82% for PD. Key speech features differentiated clinical conditions, with Total Voiced Time being the strongest positive feature for combined PSP-PD. In HD, ALS, and CTR, Ratio Extra Words, Pauses per Second, and Intelligibility were the most strongly differentiating features, respectively.

Brain-computer interfaces hold significant promise for restoring communication in individuals with partial or complete loss of the ability to speak due to paralysis from amyotrophic lateral sclerosis (ALS), brainstem stroke, and other neurological disorders. Many of the approaches to speech decoding reported in the BCI literature have required time-aligned target representations to allow successful training-a major challenge when translating such approaches to people who have already lost their voice.Approach. In this pilot study, we made a first step toward scenarios in which no ground truth is available. We utilized a graph-based clustering approach to identify temporal segments of speech production from electrocorticographic (ECoG) signals alone. We then used the estimated speech segments to train a voice activity detection (VAD) model using only ECoG signals. We evaluated our approach using a leave-one-day-out cross-validation on open-loop recordings of a single dysarthric clinical trial participant living with ALS, and we compared the resulting performance to previous solutions trained with ground truth acoustic voice recordings.Main results. Our approach achieves a median timing error of around 530 ms with respect to the actual spoken speech. Embedded into a real-time BCI, our approach is capable of providing VAD results with a latency of only 10 ms.Significance. To the best of our knowledge, our results show for the first time that speech activity can be predicted purely from unlabeled ECoG signals, a crucial step toward individuals who cannot provide this information anymore due to their neurological condition, such as patients with locked-in syndrome.Clinical Trial Information.

This study aims to describe the patient clientele of a neurological palliative outpatient clinic and the spectrum of necessary treatments and interventions. In this longitudinal analysis, clinical routine data from a single centre were collected retrospectively from adult patients. The patient characteristics related to disease and treatment were evaluated descriptively. Factors influencing the need for ventilation were modelled in a logistic regression. The required treatment effort was modelled with a zero-inflated Beta regression. Results were reported as odds ratios with 95% confidence intervals (CIs). Two hundred and thirty-two patients were included in the study. Ninety-one patients were women, 141 were men, and the mean age was 55.42\u202fyears. Neuropalliative patients represented diagnoses such as amyotrophic lateral sclerosis (ALS) (n\u202f=\u202f81), ischemic stroke (n\u202f=\u202f15), intracerebral haemorrhage (n\u202f=\u202f15), Duchenne muscular dystrophy (n\u202f=\u202f12), or craniocerebral trauma (n\u202f=\u202f10).

Cranial nerve examination (91%), swallow trials (79%), speech intelligibility tasks (85%), and diadochokinetic speech rates (65%) were frequently included in evaluations. Although 81% of clinics had access to instrumental swallowing evaluations, 32% reported performing them in fewer than 25% of patients. Communication evaluations were offered directly by 58% of clinicians, while 26% referred to an outside SLP and 16% collaborated with device representatives. Most clinicians provided patient education on swallowing (87%) and oral health (83%). However, managed practice varied widely, revealing no standardized treatment that is routinely offered. Barriers to optimal ALS care included time constraints, relevant clinical training, timing of treatment, addressing psychosocial components of care, access to resources, interdisciplinary communication, and insurance coverage (United States only). Findings reveal little consensus on symptomatic bulbar management and intervention timing. Results emphasize the urgent need for the development of a standardized minimal data set to best guide the evaluation and management of bulbar dysfunction in ALS. https://doi.org/10.23641/asha.30249997.",
        "41083392": "ID: 41083392\nTitle: [Clinical analysis of a motor neuron disease-like phenotype associated with anti-IgLON5 disease].\nAbstract: We report a case of anti-IgLON5 disease with a motor neuron disease-like presentation admitted to the Department of Neurology, Xuanwu Hospital, Capital Medical University in July 2021. The patient was a 71-year-old female who presented with the chief complaint of limb weakness persisting for 4 months. She showed progressive limb weakness accompanied by muscle atrophy. Electromyography (EMG) revealed extensive neurogenic damage. Initial serum evaluation for neural-specific autoantibodies was positive for IgLON5-Ab (1\u2236100). Repeat testing confirmed IgLON5-Ab positivity with a titer of 1\u22361 000. The patient was diagnosed with anti-IgLON5 disease and treated with methylprednisolone and immunoglobulin, leading to clinical improvement. We found four relevant articles reporting a total of 11 similar cases. Thus, in this study, we analyzed a total of 12 cases, including our patient. Based on their clinical manifestations, these cases can be categorized into two types: amyotrophic lateral sclerosis(ALS)type and isolated bulbar type. Six cases-three males and three females-presented with the ALS type. Of these, three cases had diffuse limb weakness accompanied by muscle atrophy(two cases had diffuse hyperreflexia and one had a normal tendon reflex); one case presented with neck extensor weakness and bilateral asymmetric upper extremity weakness and was hyperreflexic at the bilateral patellar tendons; one case displayed asymmetric weakness in both lower limbs with normal deep reflexes, and one case exhibited neck weakness with hyperreflexia. EMG revealed diffuse lower motor neuron disease involving two or three regions. All patients tested positive for serum anti-IgLON5 antibodies. Four were also positive for anti-IgLON5 antibodies in cerebrospinal fluid, two were negative, and six were not tested. Among the 11 patients who received immunotherapy, 4 showed partial improvement in clinical symptoms, 2 exhibited transient improvement, 2 remained stable, and 3 showed no improvement. Testing for IgLON5-Ab should be considered among patients presenting with bulbar symptoms or ALS-like features, especially those with acute or subacute onset, rapid progression, autonomic dysfunction, vocal cord paralysis requiring tracheotomy, cognitive impairment, or involuntary movements. Early diagnosis and treatment may improve clinical symptoms and reduce adverse outcomes. \u672c\u6587\u62a5\u9053\u9996\u90fd\u533b\u79d1\u5927\u5b66\u5ba3\u6b66\u533b\u9662\u795e\u7ecf\u5185\u79d12021\u5e747\u6708\u6536\u6cbb\u76841\u4f8b\u8fd0\u52a8\u795e\u7ecf\u5143\u75c5\u6837\u8868\u578b\u7684\u6297IgLON5\u75c5\u75c5\u4f8b\u3002\u60a3\u8005\u4e3a71\u5c81\u5973\u6027\uff0c\u4e3b\u56e0\u80a2\u4f53\u65e0\u529b4\u4e2a\u6708\u5165\u9662\uff0c\u4e34\u5e8a\u8868\u73b0\u4e3a\u8fdb\u884c\u6027\u7684\u56db\u80a2\u65e0\u529b\u4f34\u808c\u8089\u840e\u7f29\uff0c\u808c\u7535\u56fe\u63d0\u793a\u5e7f\u6cdb\u795e\u7ecf\u6e90\u6027\u635f\u5bb3\uff0c\u8840\u6e05\u81ea\u8eab\u514d\u75ab\u6027\u8111\u708e\u76f8\u5173\u6297\u4f53\uff1aIgLON5-Ab\u9633\u6027\uff081\u2236100\uff09\uff0c\u590d\u67e5\u6297\u4f53\u6ef4\u5ea6\uff0c\u8840\u6e05IgLON5\u6297\u4f53IgG\u4e3a1\u22361 000\uff0c\u8bca\u65ad\u4e3a\u6297IgLON5\u75c5\uff0c\u5e94\u7528\u7532\u6cfc\u5c3c\u9f99\u53ca\u4e19\u79cd\u7403\u86cb\u767d\u6cbb\u7597\u6709\u597d\u8f6c\u3002\u540c\u65f6\u68c0\u7d22\u76f8\u5173\u6587\u732e4\u7bc7\uff0c\u5171\u62a5\u905311\u4f8b\u60a3\u8005\uff0c\u7ed3\u5408\u672c\u4f8b\u60a3\u8005\u517112\u4f8b\uff0c\u6839\u636e\u4e34\u5e8a\u8868\u73b0\u53ef\u5206\u4e3a2\u79cd\u7c7b\u578b\uff1a\u808c\u840e\u7f29\u4fa7\u7d22\u786c\u5316\uff08ALS\uff09\u578b\u548c\u5355\u7eaf\u5ef6\u9ad3\u578b\u3002\u67096\u4f8b\u8868\u73b0\u4e3aALS\u578b\uff0c\u7537\u60273\u4f8b\uff0c\u5973\u60273\u4f8b\uff0c\u5176\u4e2d\u56db\u80a2\u65e0\u529b\u4f34\u6709\u808c\u840e\u7f293\u4f8b\uff082\u4f8b\u56db\u80a2\u8171\u53cd\u5c04\u4ea2\u8fdb\uff0c1\u4f8b\u8171\u53cd\u5c04\u6b63\u5e38\uff09\uff0c\u53cc\u4e0a\u80a2\u4e0d\u5bf9\u79f0\u6027\u65e0\u529b\u4f34\u9888\u4f38\u808c\u65e0\u529b1\u4f8b\uff08\u53cc\u4fa7\u819d\u53cd\u5c04\u4ea2\u8fdb\uff09\uff0c\u53cc\u4e0b\u80a2\u4e0d\u5bf9\u79f0\u6027\u65e0\u529b1\u4f8b\uff08\u6df1\u53cd\u5c04\u6b63\u5e38\uff09\uff0c\u9888\u808c\u65e0\u529b1\u4f8b\uff08\u56db\u80a2\u6df1\u53cd\u5c04\u4ea2\u8fdb\uff09\uff1b\u808c\u7535\u56fe\u68c0\u67e5\u5747\u63d0\u793a\u4e0b\u8fd0\u52a8\u795e\u7ecf\u5143\u6027\u635f\u5bb3\uff0c\u7d2f\u53ca2\u62163\u4e2a\u533a\u57df\u3002\u6240\u6709\u60a3\u8005\u8840\u6e05\u6297IgLON5\u6297\u4f53\u5747\u4e3a\u9633\u6027\uff1b\u8111\u810a\u6db2\u6297IgLON5\u6297\u4f534\u4f8b\u9633\u6027\uff0c2\u4f8b\u9634\u6027\uff0c6\u4f8b\u672a\u68c0\u6d4b\u300211\u4f8b\u60a3\u8005\u7ed9\u4e88\u4e86\u514d\u75ab\u6cbb\u7597\uff0c4\u4f8b\u60a3\u8005\u4e34\u5e8a\u75c7\u72b6\u6709\u90e8\u5206\u6539\u5584\uff0c2\u4f8b\u6cbb\u7597\u540e\u77ed\u6682\u6027\u597d\u8f6c\uff0c2\u4f8b\u75c5\u60c5\u7a33\u5b9a\uff0c3\u4f8b\u60a3\u8005\u65e0\u6539\u5584\u3002\u8868\u73b0\u4e3a\u5ef6\u9ad3\u75c7\u72b6\u6216\u808c\u840e\u7f29\u4fa7\u7d22\u786c\u5316\u75c7\u7684\u60a3\u8005\uff0c\u5c24\u5176\u662f\u6025\u6027\u6216\u4e9a\u6025\u6027\u8d77\u75c5\uff0c\u8fdb\u5c55\u8fc5\u901f\uff0c\u6216\u5b58\u5728\u81ea\u4e3b\u795e\u7ecf\u529f\u80fd\u969c\u788d\u3001\u58f0\u5e26\u9ebb\u75f9\u9700\u8981\u6c14\u7ba1\u5207\u5f00\u3001\u8ba4\u77e5\u969c\u788d\u4ee5\u53ca\u4e0d\u81ea\u4e3b\u8fd0\u52a8\u7b49\u8868\u73b0\u65f6\uff0c\u9700\u8981\u8003\u8651\u5230\u6297IgLON5\u75c5\u7684\u53ef\u80fd\uff0c\u65e9\u671f\u8bca\u65ad\u53ca\u6cbb\u7597\u6216\u53ef\u6539\u5584\u60a3\u8005\u4e34\u5e8a\u75c7\u72b6\uff0c\u51cf\u5c11\u4e0d\u826f\u7ed3\u5c40\u3002.",
        "41092928": "ID: 41092928\nTitle: Global burden of 292 causes of death in 204 countries and territories and 660 subnational locations, 1990-2023: a systematic analysis for the Global Burden of Disease Study 2023.\nAbstract: Timely and comprehensive analyses of causes of death stratified by age, sex, and location are essential for shaping effective health policies aimed at reducing global mortality. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023 provides cause-specific mortality estimates measured in counts, rates, and years of life lost (YLLs). GBD 2023 aimed to enhance our understanding of the relationship between age and cause of death by quantifying the probability of dying before age 70 years (70q0) and the mean age at death by cause and sex. This study enables comparisons of the impact of causes of death over time, offering a deeper understanding of how these causes affect global populations. GBD 2023 produced estimates for 292 causes of death disaggregated by age-sex-location-year in 204 countries and territories and 660 subnational locations for each year from 1990 until 2023. We used a modelling tool developed for GBD, the Cause of Death Ensemble model (CODEm), to estimate cause-specific death rates for most causes. We computed YLLs as the product of the number of deaths for each cause-age-sex-location-year and the standard life expectancy at each age. Probability of death was calculated as the chance of dying from a given cause in a specific age period, for a specific population. Mean age at death was calculated by first assigning the midpoint age of each age group for every death, followed by computing the mean of all midpoint ages across all deaths attributed to a given cause. We used GBD death estimates to calculate the observed mean age at death and to model the expected mean age across causes, sexes, years, and locations. The expected mean age reflects the expected mean age at death for individuals within a population, based on global mortality rates and the population's age structure. Comparatively, the observed mean age represents the actual mean age at death, influenced by all factors unique to a location-specific population, including its age structure. As part of the modelling process, uncertainty intervals (UIs) were generated using the 2\u00b75th and 97\u00b75th percentiles from a 250-draw distribution for each metric. Findings are reported as counts and age-standardised rates. Methodological improvements for cause-of-death estimates in GBD 2023 include a correction for the misclassification of deaths due to COVID-19, updates to the method used to estimate COVID-19, and updates to the CODEm modelling framework. This analysis used 55\u2008761 data sources, including vital registration and verbal autopsy data as well as data from surveys, censuses, surveillance systems, and cancer registries, among others. For GBD 2023, there were 312 new country-years of vital registration cause-of-death data, 3 country-years of surveillance data, 51 country-years of verbal autopsy data, and 144 country-years of other data types that were added to those used in previous GBD rounds. The initial years of the COVID-19 pandemic caused shifts in long-standing rankings of the leading causes of global deaths: it ranked as the number one age-standardised cause of death at Level 3 of the GBD cause classification hierarchy in 2021. By 2023, COVID-19 dropped to the 20th place among the leading global causes, returning the rankings of the leading two causes to those typical across the time series (ie, ischaemic heart disease and stroke). While ischaemic heart disease and stroke persist as leading causes of death, there has been progress in reducing their age-standardised mortality rates globally. Four other leading causes have also shown large declines in global age-standardised mortality rates across the study period: diarrhoeal diseases, tuberculosis, stomach cancer, and measles. Other causes of death showed disparate patterns between sexes, notably for deaths from conflict and terrorism in some locations. A large reduction in age-standardised rates of YLLs occurred for neonatal disorders. Despite this, neonatal disorders remained the leading cause of global YLLs over the period studied, except in 2021, when COVID-19 was temporarily the leading cause. Compared to 1990, there has been a considerable reduction in total YLLs in many vaccine-preventable diseases, most notably diphtheria, pertussis, tetanus, and measles. In addition, this study quantified the mean age at death for all-cause mortality and cause-specific mortality and found noticeable variation by sex and location. The global all-cause mean age at death increased from 46\u00b78 years (95% UI 46\u00b76-47\u00b70) in 1990 to 63\u00b74 years (63\u00b71-63\u00b77) in 2023. For males, mean age increased from 45\u00b74 years (45\u00b71-45\u00b77) to 61\u00b72 years (60\u00b77-61\u00b76), and for females it increased from 48\u00b75 years (48\u00b71-48\u00b78) to 65\u00b79 years (65\u00b75-66\u00b73), from 1990 to 2023. The highest all-cause mean age at death in 2023 was found in the high-income super-region, where the mean age for females reached 80\u00b79 years (80\u00b79-81\u00b70) and for males 74\u00b78 years (74\u00b78-74\u00b79). By comparison, the lowest all-cause mean age at death occurred in sub-Saharan Africa, where it was 38\u00b70 years (37\u00b75-38\u00b74) for females and 35\u00b76 years (35\u00b72-35\u00b79) for males in 2023. Lastly, our study found that all-cause 70q0 decreased across each GBD super-region and region from 2000 to 2023, although with large variability between them. For females, we found that 70q0 notably increased from drug use disorders and conflict and terrorism. Leading causes that increased 70q0 for males also included drug use disorders, as well as diabetes. In sub-Saharan Africa, there was an increase in 70q0 for many non-communicable diseases (NCDs). Additionally, the mean age at death from NCDs was lower than the expected mean age at death for this super-region. By comparison, there was an increase in 70q0 for drug use disorders in the high-income super-region, which also had an observed mean age at death lower than the expected value. We examined global mortality patterns over the past three decades, highlighting-with enhanced estimation methods-the impacts of major events such as the COVID-19 pandemic, in addition to broader trends such as increasing NCDs in low-income regions that reflect ongoing shifts in the global epidemiological transition. This study also delves into premature mortality patterns, exploring the interplay between age and causes of death and deepening our understanding of where targeted resources could be applied to further reduce preventable sources of mortality. We provide essential insights into global and regional health disparities, identifying locations in need of targeted interventions to address both communicable and non-communicable diseases. There is an ever-present need for strengthened health-care systems that are resilient to future pandemics and the shifting burden of disease, particularly among ageing populations in regions with high mortality rates. Robust estimates of causes of death are increasingly essential to inform health priorities and guide efforts toward achieving global health equity. The need for global collaboration to reduce preventable mortality is more important than ever, as shifting burdens of disease are affecting all nations, albeit at different paces and scales.

Although generally considered safe, concerns about complications persist, particularly in systems where FEES is not routine and professional roles differ. The aim of this study was to evaluate the safety of FEES performed by both speech-language pathologists (SLPs) and physicians, in order to provide evidence of its safety in a healthcare system where the procedure is not yet widely established and to identify patient subgroups potentially at higher risk of procedure-related complications. (2) Methods: This retrospective study analyzed 964 consecutive FEES procedures. Examinations were carried out by trained SLPs or physicians. Data included demographics, clinical status, operator qualifications, setting, and complications, classified as minor (vomiting, poor tolerance, early termination) or major (laryngospasm, epistaxis). (3) Results: The overall complication rate was 1.14% (11/964): 0.6% minor and 0.5% major. All events were self-limiting. Complication rates did not differ between SLPs (1.05%) and physicians (1.23%) or by experience, setting, drug use, penetration-aspiration scale score, or nasogastric tube. Four complications occurred in amyotrophic lateral sclerosis patients, suggesting higher risk. (4) Conclusions: FEES is safe and well tolerated when performed by either physicians or SLPs. These findings underscore the value of task sharing in dysphagia diagnostics, demonstrating that a shared model increases service capacity, reduces delays, and facilitates timely management of dysphagia.",

This cross-sectional, retrospective study collected data from medical records. Altogether, 101 individuals with dysphagia were included and stratified into two groups: the first had 56 patients diagnosed with ALS, and the second had 45 older adults. Dysphagia signs were analyzed through fiberoptic endoscopic evaluation of swallowing, using four food consistencies, classified by the International Dysphagia Diet Standardisation Initiative (IDDSI). Pharyngeal residues were classified by the Yale Pharyngeal Residue Severity Rating Scale (YPRSRS), and oral intake by the Functional Oral Intake Scale (FOIS). The ALS group had differences in multiple swallows with one IDDSI consistency; posterior oral leakage, pharyngeal residues, and laryngeal penetration with three consistencies; and aspiration with one consistency. Individuals with more than 3 years since diagnosis had differences in the onset of the pharyngeal response in the pyriform sinuses, moderate pharyngeal residues, and oral intake. The ALS group had significant differences in the occurrence of multiple swallows, posterior oral leakage, pharyngeal residues, penetration, and aspiration with three IDDSI consistencies. Furthermore, the time since diagnosis was a determining factor for all three parameters.

        "41267082": "ID: 41267082\nTitle: Expanding research and care for Leigh syndrome: efforts of a patient-led advocacy organization.\nAbstract: BACKGROUND: Leigh syndrome is a rare, progressive neurometabolic disorder caused by pathogenic variants in over 110 mitochondrial or nuclear genes. Its clinical and genetic heterogeneity creates challenges for diagnosis, care, and research. Cure Mito Foundation, a parent-led nonprofit established in 2018 to develop a gene therapy for SURF1-related Leigh syndrome, has since evolved into a global organization supporting individuals and families worldwide affected by all forms of Leigh syndrome. METHODS: This article describes the multifaceted efforts of Cure Mito Foundation to accelerate research and support for Leigh syndrome through family-led engagement and collaborative scientific partnerships. Strategies include funding the development of diverse disease models, gene therapies, drug repurposing pipelines, and a global patient registry. Emphasis is placed on co-production with affected families, sharing of biospecimens and data, and alignment with regulatory and research standards. RESULTS: The Leigh Syndrome Global Patient Registry comprises over 400 participants from 48 countries, with data made available to qualified researchers, and results shared regularly with the patient community to promote transparency and trust. Notable research accomplishments of Cure Mito include facilitating the development of multiple gene therapy candidates, patient-derived organoids and animal models, and repurposed drugs now entering early-phase trials. Cure Mito also played a key role in the launch of the Mitochondrial and Inherited Metabolic Disease Taskforce, led by the Critical Path Institute (C-Path), to integrate registry and clinical data into the Rare Disease Cures Accelerator platform. Additional efforts include community-developed educational tools, international awareness campaigns, and support programs tailored to the unique needs of Leigh syndrome families. CONCLUSIONS: Through relentless effort and dedication, the Cure Mito Foundation has shown that a small group of determined individuals can drive extraordinary change. By building a global patient registry, advancing data sharing and research, developing patient-centric education and support, and facilitating collaboration among scientists, clinicians, and families, the Foundation has created momentum toward effective treatments. With support from the Chan Zuckerberg Initiative\u2019s Rare As One grant, Cure Mito is poised to expand its impact even further. Leigh syndrome is a severe genetic disorder that begins in early childhood and leads to the gradual loss of physical and developmental abilities. It can be caused by variations in over 110 different genes and can affect multiple organs and systems in the body. Cure Mito Foundation is a nonprofit organization founded by parents of children with Leigh syndrome. Since its inception in 2018, the Foundation has evolved into a global initiative to support children and families affected by this rare condition. This article highlights the Cure Mito Foundation\u2019s efforts to advance research and provide support to families. The Foundation partners with scientists to explore potential treatments, including gene therapy, drug repurposing, and mitochondrial genome editing. It also established a global patient registry to collect valuable data from families, enabling researchers to better understand Leigh syndrome.

Through international collaboration and a strong, engaged community, Cure Mito Foundation is accelerating progress toward better care and future cures.",
        "41269662": "ID: 41269662\nTitle: Unrevealing the sequence of dysphagia progression in ALS: an event-based, FEES-driven staging approach.\nAbstract: Dysphagia drives morbidity and mortality in amyotrophic lateral sclerosis (ALS), yet staging systems treat it as a binary milestone and do not capture its trajectory. Reports diverge on the earliest abnormality, with some citing cohesive-bolus inefficiency and others thin-liquid impairment. Furthermore, how these findings relate to patient-perceived dysphagia remains unclear. In a prospective cohort, 78 incident ALS patients underwent one or more fiberoptic endoscopic evaluations of swallowing (FEES), yielding 108 assessments. Pharyngeal residue for four consistencies was rated with a validated scale. An event-based model (EBM) inferred the temporal order of abnormalities and defined a five-stage, FEES-based dysphagia staging system (DSS). Construct, convergent, discriminant, and prognostic validity were tested against established measures; responsiveness was assessed in patients with longitudinal FEES. The EBM identified a consistent sequence of swallowing impairment: solids, semisolids, liquids, saliva. Patient-perceived dysphagia occurred in 38% of DSS 1-2 evaluations versus 100% of DSS 3-4. The DSS showed construct validity by distinguishing bulbar- from spinal-onset ALS and convergent validity with the ALSFRS-R bulbar subscore and LMN bulbar score. Discriminant validity was supported by weak, non-significant associations with spinal/respiratory measures. Agreement with King's staging was moderate, and all King's stage IV patients mapped to DSS stages 3-4. The DSS was responsive to change (Stuart-Maxwell \u03c7\u00b2 = 11.034; p\u2009=\u20090.026). The EBM reconciles prior discrepancies: pathophysiology begins with solids, whereas symptom recognition typically coincides with liquid-phase residue. The FEES-based DSS is reproducible and clinically meaningful for tracking bulbar involvement and identifying higher-risk patients.",
        "41283495": "ID: 41283495\nTitle: Acoustic Vowel Metrics as Correlates of Dysphagia and Dysarthria in Brainstem Neurodegenerative Diseases.\nAbstract: Background/Objectives: Swallowing and speech rely on shared brainstem circuits coordinating oropharyngeal motor functions. In neurodegenerative diseases affecting the brainstem-such as progressive supranuclear palsy (PSP), amyotrophic lateral sclerosis (ALS), and multiple system atrophy (MSA)-bulbar dysfunction often impairs tongue propulsion and motility, affecting both swallowing (dysphagia) and phonation (dysarthria). This study aimed to investigate whether vowel-based acoustic features are associated with swallowing severity in brainstem-related disorders and to explore their potential as surrogate markers of bulbar involvement. Methods: This was a cross-sectional observational study. Thirty-one patients (13 PSP, 12 ALS, 6 MSA) underwent clinical dysarthria assessment, acoustic analysis of the first (F1) and second (F2) formants during sustained phonation of /a/, /i/, /e/, and /u/, and swallowing evaluation using standardized clinical scales (DOSS, FOIS, ASHA-NOMS) and fiberoptic endoscopic evaluation (Pooling Score, Penetration-Aspiration Scale). The vowel space area (tVSA, qVSA) and Formant Centralization Ratio (FCR) were computed. Results: Significant correlations emerged between acoustic vowel metrics and dysphagia severity, especially for liquids. The FCR showed strong correlations with DOSS (\u03c1 = -0.660, p < 0.0001), FOIS (\u03c1 = -0.531, p = 0.002), ASHA-NOMS (\u03c1 = -0.604, p < 0.0001), and instrumental scores for liquids: the Pooling Score (\u03c1 = 0.538, p = 0.002) and PAS (\u03c1 = 0.630, p < 0.0001). VSA measures were also associated significantly with liquid swallowing impairment. F2u correlated with dysarthria severity and all liquid-related dysphagia scores. Conclusions: Vowel-based acoustic parameters, particularly FCR and F2u, reflect the shared neuromotor substrate of articulation and swallowing. Acoustic analysis may support early detection and monitoring of bulbar dysfunction, especially where instrumental assessments are limited.",
        "41314122": "ID: 41314122\nTitle: Global vs. segmental acoustic features for dysarthria assessment in motor neuron diseases.\nAbstract: Dysarthria, a common symptom of motor neuron disease (MND), is primarily assessed through perceptual evaluations that are subjective, time-consuming, and require expert training. Acoustic analysis provides an objective alternative, leveraging either \"global\" features extracted from the entire speech signal or \"segmental\" features derived from individual phonemes (e.g., vowels). While segmental features offer finer-grained acoustic insights, their extraction has traditionally required manual segmentation, making the process time-consuming. This study explored the use of the Montreal Forced Aligner (MFA) for automatic vowel segmentation and compared the diagnostic utility of global versus segmental acoustic features in two machine learning tasks: dysarthria detection (i.e., distinguishing healthy controls (HCs) from speakers with dysarthria) and dysarthria severity classification (i.e., pre-, early-, and late-symptomatic stratification). Speech data were collected from 104 speakers with MND and 99 HCs. Global features were computed from voiced segments, while segmental features were derived from automatically aligned vowels. Four tree-based classifiers - Decision Tree, Random Forest, XGBoost, and LightGBM - were trained using 10-fold cross-validation. Feature importance was assessed using SHAP values, and statistical tests identified features with significant group differences. The MFA achieved alignment accuracy of at least 86% for healthy and early-symptomatic speakers, declining to 72% in late-stage dysarthria. For dysarthria detection, global features were significantly more effective than segmental features only in the XGBoost model. In contrast, segmental features significantly outperformed global features in dysarthria severity classification across all ensemble classifiers. These findings support the use of automated segmental analysis as an objective, viable, and clinically meaningful approach for assessing dysarthria in MNDs.",
        "41337107": "ID: 41337107\nTitle: Detection of Amyotrophic Lateral Sclerosis with Computer Audition: An Impact Analysis of Different Speech Tasks.\nAbstract: We investigate the performance difference between training generic and task-based systems for the automatic detection of patients with Amyotrophic Lateral Sclerosis (ALS) from speech. We exploit the paralinguistic information embedded in their speech while producing the sustained vowel /a:/, repeating the syllables /da/-/da/ and /da/-/ba/ - separately -, reading a text passage, and describing a picture. While the former system consists of a single model, the latter is composed of five task-dedicated models, each one in charge of processing the speech samples corresponding to each task. We also analyse the performance of each task-dedicated model individually. We conduct our experiments on the novel, German-speaking AIMnd dataset. The obtained results - assessed in terms of the Unweighted Average Recall (UAR) - indicate that the task-based systems outperform the generic ones in two out of the four scenarios explored. The generic system only outperforms the task-based system in one scenario. In terms of the task-dedicated models, the SVClinear-based classifier exploiting the extended Geneva Minimalistic Acoustic Parameter Set (eGeMAPS) extracted from the sustained vowel /a:/ production task yields the best performance on the Test set with a UAR of 92%.",

As interest in speech analysis grows, distinguishing between conditions becomes critical for reliable diagnosis and assessment. This pilot study explores speech biosignatures in two distinct neurodegenerative conditions: (1) mild traumatic brain injuries (eg, concussions) and (2) Parkinson disease (PD) as the neurodegenerative condition. The study included speech samples from 235 participants (97 concussed and 94 age-matched healthy controls, 29 PD and 15 healthy controls) for the PaTaKa test and 239 participants (91 concussed and 104 healthy controls, 29 PD and 15 healthy controls) for the Sustained Vowel (/ah/) test. Age-matched healthy controls were used. Young age-matched controls were used for concussion and respective age-matched controls for neurodegenerative participants (15 healthy samples for both tests). Data augmentation with noise was applied to balance small datasets for neurodegenerative and healthy controls. Machine learning models (support vector machine, decision tree, random forest, and Extreme Gradient Boosting) were employed using 37 temporal and spectral speech features. A 5-fold stratified cross-validation was used to evaluate classification performance. For the PaTaKa test, classifiers performed well, achieving F 1-scores above 0.9 for concussed versus healthy and concussed versus neurodegenerative classifications across all models. Initial tests using the original dataset for neurodegenerative versus healthy classification yielded very poor results, with F 1-scores below 0.2 and accuracy under 30% (eg, below 12 out of 44 correctly classified samples) across all models. This underscored the need for data augmentation, which significantly improved performance to 60%-70% (eg, 26-31 out of 44 samples) accuracy. In contrast, the Sustained Vowel test showed mixed results; F 1-scores remained high (more than 0.85 across all models) for concussed versus neurodegenerative classifications but were significantly lower for concussed versus healthy (0.59-0.62) and neurodegenerative versus healthy (0.33-0.77), depending on the model. This study highlights the potential of speech features as biomarkers for neurodegenerative conditions. The PaTaKa test exhibited strong discriminative ability, especially for concussed versus neurodegenerative and concussed versus healthy tasks, whereas challenges remain for neurodegenerative versus healthy classification. These findings emphasize the need for further exploration of speech-based tools for differential diagnosis and early identification in neurodegenerative health.",

These disorders are clinically heterogeneous and therapeutically challenging, but advances in discovery science and trial methodology offer hope for translation to new treatments. Against this background, there is an urgent unmet need for biomarkers to aid with early and accurate diagnosis, prognosis and monitoring throughout the care pathway and in clinical trials.Investigations routinely used in clinical care and trials are often invasive, expensive, time-consuming, subjective and ordinal. Speech data represent a potentially scalable, non-invasive, objective and quantifiable digital biomarker that can be acquired remotely and cost-efficiently using mobile devices, and analysed using state-of-the-art speech signal processing and machine learning approaches. This prospective case-control observational study of multiple NDDs aims to deliver a deeply clinically phenotyped longitudinal speech dataset to facilitate development and evaluation of speech biomarkers. People living with dementia, motor neuron disease, multiple sclerosis and Parkinson's disease are eligible to participate. Healthy individuals (including relatives or carers of participants with neurological disease) are also eligible to participate as controls. Participants complete a study app with standardised speech recording tasks (including reading, free speech, picture description and verbal fluency tasks) and patient-reported outcome measures of quality of life and mood (EuroQol-5 Dimension-5 Level, Patient Health Questionnaire 2) every 2 months at home or in clinic.

This degeneration leads to a gradual muscle weakness, dysarthria, dysphagia, respiratory insufficiency, and, in some patients, alterations in cognitive and behavioral performance. Regardless of advancements made in pharmacological and gene-targeted interventions, a definitive curative treatment remains elusive. Consequently, rehabilitation plays a pivotal role in preserving autonomy, participation, and overall quality of life. This review outlines the current evidence and clinical approaches related to multidisciplinary rehabilitation in ALS. It covers physical and occupational therapy, respiratory, speech and language, psychological, and palliative care domains. Evidence supports moderate tailored exercise programs, early respiratory therapy, and structured management of mobility deficits, spasticity, pain, dysphagia, and communication impairments as key elements of symptomatic treatment. Psychological and social support, which includes the involvement of caregivers and relatives, enhances emotional well-being and coping resilience. Even with progressive development of gene-targeted and disease-modifying therapies, rehabilitation will stay relevant for maintaining long-term motor function. This review highlights the need for standardized, evidence-based rehabilitation protocols and intensified neurorehabilitation research to strengthen clinical outcomes and quality of life as key therapeutic goals in ALS management.",
        "41396714": "ID: 41396714\nTitle: What can vowel acoustics reveal about the communicative participation of people living with ALS?\nAbstract: Objective: Bulbar dysfunction often diminishes the accuracy and speed of the tongue, lip, and jaw movements necessary for speech production. Vowel acoustic features derived from speech recordings can serve as sensitive markers of articulatory accuracy and movement timing. We examined whether degraded speech caused by amyotrophic lateral sclerosis (ALS), assessed through vowel acoustic features, was associated with communicative participation restrictions. As a secondary aim, we assessed the association of two global speech characteristics, rate and intelligibility, with vowel features and communicative participation. Materials & Methods: Thirty-three people with ALS (plwALS) recorded a reading passage and completed surveys using a smartphone application. Speaking rate and acoustic vowel features (duration, vowel articulation index [VAI]) were extracted from the recordings. Three speech-language pathologists rated speech intelligibility. Communicative participation was assessed using the Communicative Participation Item Bank (CPIB) short form. Bivariate correlation, partial correlation, and regression analyses were used to evaluate the associations between vowel features, intelligibility, speaking rate, and CPIB scores. Results: Significant bivariate correlations, ranging from rs\u2009=\u2009-0.39 to rs\u2009=\u20090.64, were found between speech variables and CPIB scores. A combined regression model including VAI, vowel duration, and sex explained 52% of the variance in CPIB scores. Including speaking rate or intelligibility in the partial correlation analysis attenuated the associations between vowel acoustics and CPIB. Conclusions: Vowel features and global dysarthria characteristics are linked to communicative participation in ALS. Clinical practices designed to target vowel production, speaking rate, and intelligibility may help to maintain daily communication in ALS.",

Pridopidine, a selective sigma-1 receptor agonist, was evaluated in Regimen D of the HEALEY ALS Platform Trial. Although the primary endpoint (ALS Functional Rating Scale-Revised (ALSFRS-R) total score accounting for survival at 24\u00a0weeks) was not met, a predefined subgroup analysis suggested slowed disease progression in ALS patients with definite and early disease (<18\u00a0months from onset). This report presents an exploratory analysis that further investigates pridopidine in rapidly progressing participants with definite/probable ALS and early-disease, where treatment effects may be more pronounced. Methods: The randomized, double-blind, placebo-controlled phase 2 trial assigned participants to pridopidine 45\u2009mg bid or placebo, and placebo patients were shared across four trial regimens. The primary outcome was ALSFRS-R total score, with secondary outcomes assessing respiratory, bulbar, and speech functions. Results: Of 163 participants randomized to Regimen D, 72 met subgroup criteria (pridopidine: n\u00a0=\u00a037; shared placebo: n\u00a0=\u00a035). At week 24, pridopidine slowed ALSFRS-R total score decline (32%; \u03942.90, p\u00a0=\u00a00.03) and slowed decline of ALSFRS-R respiratory function (62%; \u03941.20, p\u00a0=\u00a00.03) and dyspnea (88%; \u03940.85, p\u00a0=\u00a00.005).

We conducted a retrospective study including 50 ALS patients evaluated in a phoniatrics consultation with available sustained vowel recordings, demographic data, and functional assessments. Nested logistic regression models were developed to predict clinical outcomes, progressively incorporating demographic variables, functional indices (Grade, Roughness, Breathiness, Asthenia, Strain, and Barthel), acoustic features (fundamental frequency, jitter, shimmer, harmonics-to-noise ratio), and biomechanical voice parameters (Pr1-Pr22). Model performance was assessed using receiver operating characteristic curves and area under the curve (AUC) comparisons via DeLong tests. Stepwise Akaike Information Criterion\u00a0(StepAIC) was applied to optimize the final model. A Cox proportional hazards model was used to evaluate the association between voice parameters and survival time. The final StepAIC model, which included a subset of biomechanical features, achieved excellent predictive performance (AUC\u00a0=\u00a00.903, 95% confidence interval: 0.816-0.989), significantly outperforming baseline and acoustic-only models. Bootstrapping confirmed the model's robustness and generalizability.

Early detection of bulbar symptoms is crucial for timely diagnosis and intervention; however, variability in symptom progression complicates clinical assessment. This retrospective observational study aimed to classify patients with ALS into three groups - spinal onset, spinal onset with bulbar involvement, and bulbar onset - and to identify speech evaluation metrics that effectively differentiate these groups. Data from 68 patients with ALS were retrospectively analyzed. Speech samples were collected and evaluated for alternating motion rate (AMR), maximum phonation time (MPT), nasality, maximum tongue pressure (MTP), speech rate, and speech intelligibility. Group comparisons and receiver operating characteristic (ROC) curve analyses were conducted to assess discriminatory ability. AMR significantly differed among the three groups, with the spinal-onset group demonstrating the highest rates and the bulbar-onset group showing the lowest rates. ROC analysis indicated that AMR exhibited excellent discriminatory power, particularly in distinguishing spinal-from bulbar-onset ALS. Significant differences were also observed in MTP, nasality, speech rate, and speech intelligibility, although some metrics were less effective in differentiating the intermediate group. No significant group differences were found in MPT. These findings suggest that the AMR is a sensitive and easily administered measure for detecting bulbar symptoms and distinguishing ALS subtypes. The intermediate characteristics observed in the spinal-onset with bulbar involvement group support this classification as a distinct clinical phenotype. Combining AMR with secondary measures such as MTP, nasality, speech rate, and speech intelligibility may enhance early detection of bulbar symptoms and improve clinical decision-making.",

These disorders profoundly affect patient health and quality of life through complex sensorimotor impairments. Objective: The aims was to provide a comprehensive, evidence-based review of the neuroanatomical substrates, pathophysiology, diagnostic approaches, and management strategies for dysphagia and dysarthria in neurodegenerative diseases with emphasis on their multisystem nature and integrated treatment approaches. Methods: A narrative literature review was conducted using PubMed, Scopus, and Web of Science databases (2000-2024), focusing on Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), progressive supranuclear palsy (PSP), and multiple system atrophy (MSA). Search terms included \"dysphagia\", \"dysarthria\", \"neurodegenerative diseases\", \"neural networks\", \"swallowing control\" and \"speech production.\" Studies on neuroanatomy, pathophysiology, diagnostic tools, and therapeutic interventions were included. Results: Contemporary neuroscience demonstrates that swallowing and speech control involve extensive neural networks beyond the brainstem, including bilateral sensorimotor cortex, insula, cingulate gyrus, basal ganglia, and cerebellum. Disease-specific patterns reflect multisystem involvement: PD affects basal ganglia and multiple brainstem nuclei; ALS involves cortical and brainstem motor neurons; MSA causes widespread autonomic and motor degeneration; PSP produces tau-related damage across multiple brain regions. Diagnostic approaches combining fiberoptic endoscopic evaluation, videofluoroscopy, acoustic analysis, and neuroimaging enable precise characterization. Management requires multidisciplinary Integrated teams implementing coordinated speech-swallowing therapy, pharmacological interventions, and assistive technologies.

To investigate the early functional consequences of TDP-43 mislocalization, we generated Caenorhabditis elegans models expressing either wild-type human TDP-43 or a variant with a mutated nuclear localization signal (\u0394NLS), specifically in serotonergic neurons. These neurons were chosen because in C. elegans they regulate well-characterized behaviors, providing a straightforward readout of neuronal function. We found that expression of either TDP-43 variant impaired serotonin-dependent behaviors-including pharyngeal pumping, egg-laying, and locomotion slowing upon food encounter-with the cytoplasmic \u0394NLS form causing more severe deficits. These behavioral impairments are evident even while the serotonergic neurons remain apparently normal in structure, suggesting that neuronal dysfunction precedes overt neurodegeneration. Moreover, the serotonergic HSN neurons that control egg-laying were also partially responsive to the selective serotonin reuptake inhibitor fluoxetine, suggesting that neurotransmitter release remains functional to some extent. Altogether, our findings demonstrate that TDP-43 expression causes neuronal dysfunction leading to behavioral deficits, even in the absence of detectable structural pathology and that its mislocalization to the cytoplasm results in more severe behavioral impairments. This C. elegans model provides a genetically tractable system to dissect early mechanisms of TDP-43-mediated neuronal dysfunction and to identify therapeutic strategies targeting predegenerative stages of ALS/FTD.",

Few studies have examined the usefulness of ultrasonographic tongue thickness measurement in patients with ALS, but its association with physiological measures remains unclear. Ten patients with ALS underwent tongue thickness measurement using ultrasonography. Clinical assessments including the Korean version of the ALS Functional Rating Scale-Revised (K-ALSFRS-R), Functional Oral Intake Scale (FOIS), Eating Assessment Tool-10 (EAT-10), Dysphagia Handicap Index, Korean version of the Swallowing Quality of Life Questionnaire, Mini Nutritional Assessment-Short Form (MNA-SF), handgrip strength, and bioelectrical impedance analysis for skeletal muscle index (SMI) were performed. Swallowing physiology was evaluated using the Modified Barium Swallow Impairment Profile (MBSImP), Penetration-Aspiration Scale. Simple and partial Pearson's correlation analyses as well as univariate regression were performed with adjustments for age, sex, and body mass index (BMI). Tongue thickness showed significant associations with multiple functional and systemic measures in the unadjusted analyses, including FOIS, EAT-10, MNA-SF, BMI, SMI, K-ALSFRS-R. After adjustment, the most consistent associations were observed with the MBSImP oral, pharyngeal, and combined phase scores. Tongue ultrasonography may serve as a radiation-free method to preliminarily assess bulbar involvement in ALS. Tongue thickness was most specifically associated with dysphagia outcomes, particularly MBSImP. Given the feasibility design and small sample size, larger longitudinal studies are warranted to confirm its clinical utility in monitoring the progression of dysphagia in patients with ALS.",

A\u00a0significant proportion of this burden is preventable through targeted strategies applied across the human lifespan. This narrative review synthesizes key evidence-based preventive measures in otology and provides practical recommendations for clinicians. A\u00a0selective review of the current literature was conducted, including national clinical guidelines, systematic reviews, epidemiological studies, and pivotal clinical trials. Key preventive measures begin before birth with maternal vaccinations and hygiene counseling as well as screening for syndromes or congenital cytomegalovirus infection. Universal newborn hearing screening is a\u00a0cornerstone of early diagnosis and intervention, enabling superior outcomes with cochlear implantation or emerging gene therapies. Recommended childhood immunizations, noise protection, cautious use of ototoxic medications, and managing lifestyle-related risk factors are effective strategies for preventing acquired hearing loss. Furthermore, auditory rehabilitation with hearing aids or implants is crucial for tertiary prevention, mitigating secondary consequences such as social isolation and cognitive decline. A\u00a0multifaceted, proactive, life-course approach to hearing health is essential to reduce the burden of hearing loss. Otolaryngologists play a\u00a0central role in implementing these preventive strategies, from counseling expectant parents to ensuring timely rehabilitation in older adults.

Methods: A systematic review was conducted following a pre-registered protocol. Databases were searched for studies involving people living with ALS that addressed timing of assistive technology interventions for communication or technology control. Screening and data extraction were completed in duplicate, findings were synthesized using a thematic analysis, and relevant findings presented as a descriptive summary. Results: Twenty-eight studies met the inclusion criteria. Evidence focused overwhelmingly on communication support rather than wider assistive technology interventions. Need for a communication aid typically occurs between one and five years from diagnosis and the timing of this varies significantly according to the site of onset of ALS. There are significant variations in the timing of changes for individuals within these groupings and there are likely a larger number of groupings that would be clinically useful. A significant correlation between changes in speaking rate and intelligibility has been shown. Once changes to speech do start to occur then the time to the loss of functional speech appears relatively consistent across the types of ALS. Conclusion: Current best practice guidelines are not reflective of the findings of this review and do not support professionals in identifying how to provide timely support. Monitoring speech changes systematically may support timely intervention. There is potential for individual level predictive modeling to help support people living with ALS to be proactive and prepared for changes.",

Respiratory dysfunction due to muscle weakness is the primary cause of death; without mechanical ventilation, death typically occurs within 2 to 5 years after onset. Mecobalamin, an active form of vitamin B12, is thought to suppress homocysteine-induced neuronal cell death in ALS by acting as a coenzyme for methionine synthase, which catalyzes the conversion of homocysteine to methionine. Since the 1990s, research on neurodegenerative diseases supported by Japan's Ministry of Health, Labour and Welfare has suggested that high-dose mecobalamin may confer clinical benefits in ALS. This led to the initiation of clinical development. A Phase II/III double-blind, placebo-controlled comparative trial was conducted, but did not meet its primary endpoint. Based on these trial findings, an investigator-initiated Phase III placebo-controlled, double-blind comparative trial was conducted primarily at Tokushima University Hospital, targeting patients who developed ALS within one year before starting the trial. The trial demonstrated the efficacy of high-dose mecobalamin in slowing the decline in the Revised ALS Functional Rating Scale total score, which was the primary endpoint. Safety was also confirmed. Based on these results, mecobalamin received regulatory approval in September 2024 for the indication \"slowing the progression of functional impairment in ALS.\" It is expected to offer a new treatment option for patients with ALS.",

This study aimed to develop and validate a simple, smartphone-based task for the objective assessment of tongue movements and to examine their association with clinical variables. 37 ALS patients and 20 age- and sex-matched controls performed a tongue lateralization task, recorded with a smartphone. A deep-learning U-Net++-based model was used for segmentation and feature extraction. The frequency and maximum amplitude of tongue movements were quantified. Clinical measures included the ALS Functional Rating Scale-revised (ALSFRS-r) bulbar sub-scores, tongue fasciculations, jaw jerk, and tongue \"spasticity\". Between-group differences and associations between tongue metrics and clinical features were assessed. The U-Net++-based model achieved robust segmentation performance. Patients showed lower tongue movement frequency than controls (0.14 vs. 0.40, t = -9.58, p < 0.001). Normalized frequency was associated with dysarthria (t = -3.13, p = 0.003) but not dysphagia (t = -1.05, p = 0.30). Normalized frequency (t = 2.77, p = 0.009) and tongue \"spasticity\" (t = -2.57, p = 0.015) were both associated with speech performance in a multiple-regression model (R = 0.51, adjusted R2 = 0.43). Our method provides an objective, minimally invasive measure of bulbar function in ALS, which correlates with clinical ratings and may detect subtle impairments not captured by standard assessments. This approach offers a promising tool for remote monitoring and may support more effective disease management.",

The vowel space of these speakers is often characterized by centralization and lowering, negatively affecting intelligibility. In two experiments, listeners identified vowels produced by PALS in habitual speech (non-interactive), clear speech (non-interactive), and interactive matching. Clear speech and interactive matching elicited more intelligible vowels than habitual speech. Interactive matching productions were equal to or more intelligible than clear speech productions depending on vowel. These data represent a preliminary step to understanding how the dynamics of communicative interaction may shape vowel intelligibility.",

The \"ALS-OPM\" classification is based on the onset region (O), the propagation of motor symptoms (P), and the degree of clinical upper (UMN) and/or lower (LMN) motor neuron dysfunction (M). An international ALS expert focus group was held in September 2025, followed by a consensus process through which revisions of the OPM classification were finalized. Onset (O1-4) identifies first motor symptoms as relating to the head (O1), distal/proximal arm (O2d/p), respiratory/axial trunk (O3r/a), or distal/proximal leg (O4d/p). Onset symptoms are defined by weakness or slowed, poorly coordinated voluntary movements in the muscles of the head, arm, trunk, or leg, including dysarthria, dysphagia, dysphonia, dyspnea, and axial instability. Propagation (P1(n)) or absence of propagation (P0(n)) of motor symptoms from the onset region to another body region are designated, where n denotes the number of months from onset to propagation or assessment. The degree of UMN dysfunction (slowed, poorly coordinated voluntary movements, hyperreflexia and/or spastic muscle tone, emotional lability) and/or LMN dysfunction (weakness with associated muscle atrophy) is classified as follows: balanced UMN and LMN dysfunction (M0); dominant (M1d) or pure UMN dysfunction (M1p); dominant (M2d) or pure LMN dysfunction (M2p); and dissociated UMN/LMN dysfunction (M3), in which the arms and legs predominantly show LMN and UMN involvement, respectively. The revised ALS-OPM classification aims to make it routine, practical and feasible to capture phenotype in clinical practice and therapeutic trials.",

An anonymous online survey was distributed via MND organisations and groups to the Australian MND community. Two hundred and fourteen individuals completed the survey. Of those, 44.8% (n\u00a0=\u00a096) were HCPs, with the remaining consisting of people living with MND, genetic carriers, and carers. The following areas were rated as extremely important and should be included in the guideline: diagnosis, service delivery models, clinical care management, caregiver support, and palliative care; while views on genetic testing and cognitive assessment were mixed. Participants highlighted a need for holistic care which considered emotional/psychological and physical aspects of MND. People with MND and their carers want the Australian MND care guideline to highlight proactive and coordinated support prioritising quality of life, while maintaining independence for as long as possible. Identifying priorities is a fundamental step that will shape the forthcoming Australian MND care guideline. This methodology ensures the voices of those with lived experience and interest holders are incorporated from the outset. The responses to the online survey highlight the importance of proactive, coordinated, and multidisciplinary approaches for people living with motor neurone disease (MND).Holistic care should be integrated into healthcare settings that address both the physical and emotional/psychological needs of individuals with MND and their carers.Early intervention and ongoing review in areas such as nutrition, respiratory management, communication, and assistive technologies are critical to support optimal outcomes.The responses highlight the need for clear communication pathways and equitable access to healthcare and support services across Australia.Incorporating the perspectives of people with MND, carers, and healthcare professionals into guideline development can ensure rehabilitation practices are person-centred, responsive, and aligned with lived experiences.",
        "41872984": "ID: 41872984\nTitle: Muscle MRI and Muscle Ultrasound Applications in MND/ALS: Academic Insights and Clinical Opportunities.\nAbstract: There is an unmet need for the clinically relevant ALS biomarkers to facilitate an accurate diagnosis in suspected cases, monitor disease progression and evaluate response to therapy in clinical trials. While the MND/ALS literature is dominated by innovative brain studies, motor disability in ALS is primarily driven by neurogenic muscle change impacting mobility, dexterity, respiratory and bulbar function. With the intention of raising awareness of muscle-derived imaging markers in ALS, a systematic review has been conducted. Study designs, imaging methods, data interpretation frameworks, and cohort characteristics were systematically evaluated to identify innovative approaches and barriers to clinical implementation. A total of 219 studies were screened and 73 original studies selected for systematic review; 37 muscle MRI studies and 36 studies using ultrasound, PET or CT. All of the selected studies successfully captured ALS-associated muscle degeneration and their methods included the evaluation of muscle dimensions (thickness/volumes n\u2009=\u200934), 'acute' denervation (water content, n\u2009=\u200915), fasciculation counts (n\u2009=\u200914), 'chronic' neurogenic change (fat content, n\u2009=\u200921), metabolic changes (n\u2009=\u20094), diffusion alterations (n\u2009=\u20098) and echo intensity changes (n\u2009=\u200913). Despite the huge impact of lower motor neuron dysfunction on the patients' independence, survival and quality of life, muscle imaging is a glaringly overlooked frontier of MND/ALS research. This is a missed opportunity, as a variety of non-invasive quantitative muscle imaging techniques have been successfully used in other neurological conditions; these protocols are easy to implement on commercial MRI and ultrasound platforms and recent studies have demonstrated their ease of use and potential clinical utility.",

While NPCs primarily localize to the nuclear envelope (NE), they also appear in cytoplasmic endoplasmic reticulum (ER) membranes called annulate lamellae (AL). Though discovered in the mid-20th century, AL's function and biogenesis remain unclear. Previously considered exclusive to embryonic and malignant cells, we find AL in somatic mammalian cells. Under normal conditions, AL store pre-assembled AL-NPCs that integrate into the NE, producing approximately one-third of newly formed nuclear pores and supporting nuclear expansion during G1. Upon pathological stimuli, AL transfer to the NE is impaired, leading to their cytoplasmic accumulation. RanBP2 (Nup358) is essential for AL biogenesis, with its phenylalanine-glycine repeats promoting AL-NPC scaffold oligomerization. ER-associated Climp63 (CKAP4) directs AL-NPCs to ER sheets and the NE. This AL-driven nuclear pore formation is complementary to the canonical routes, constituting a distinct NPC assembly pathway. Our work uncovers the biogenesis mechanism of AL and the nuclear function of this key cellular organelle.",

Although acoustic voice analysis can detect phonatory alterations in ALS, its ability to differentiate clinical phenotypes remains limited. This study investigated whether biomechanical voice parameters provide complementary information for characterizing bulbar involvement across bulbar-onset ALS (ALS-B) and spinal-onset ALS (ALS-S) and explored their association with clinical and functional measures. Methods: This cross-sectional observational study included 50 patients with ALS (20 ALS-B, 30 ALS-S) and 50 controls with non-neurological voice disorders. Sustained vowel phonation was analyzed using acoustic measures and biomechanical voice parameters derived from a standardized model of vocal fold vibration. Perceptual voice severity was assessed using the GRBAS scale, while functional status was evaluated with the ALS Functional Rating Scale-Revised (ALSFRS-R) and the Barthel Index. Associations with clinical measures were explored in secondary analyses. Results: Compared with controls, ALS patients showed significant differences in acoustic measures and several biomechanical parameters related to glottal closure and vibratory stability. Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability. Unexpectedly, ALS-B showed greater perceptual voice severity and higher Barthel Index scores than ALS-S, while no differences were observed in global ALSFRS-R total scores. Conclusions: Biomechanical voice analysis appears to capture physiologically meaningful alterations in vocal fold function in ALS and provides complementary information for characterizing bulbar motor involvement across clinical phenotypes, particularly ALS-B disease. When combined with acoustic and clinical assessments, this approach may enhance the evaluation of bulbar involvement and functional status in ALS.",

In the Community of Madrid, the ALS Network was established to improve patient care. In April 2024, the Specialised Day Care Centre for ALS (CEADELA) was inaugurated, complementing the care provided by the ALS Network. The aim of this study was to describe the experience of CEADELA during its first six months. A retrospective descriptive study was conducted on a cohort of CEADELA patients between April and October 2024. Clinical, functional, and therapeutic data were analysed, along with overall satisfaction levels. A total of 91 patients were included, with a mean age of 65.2 years (SD 11); of these, 59 (64.8%) were men. Most had spinal-onset ALS and were receiving treatment with riluzole. A significant increase was observed in the use of physiotherapy, speech therapy, and occupational therapy after referral to the centre. Functionality significantly declined over six months. The mortality rate was 12.1% (18.2% opted for assisted dying). Overall, 76 patients (83.5%) responded to the survey, with 100% reporting satisfaction or high satisfaction with the centre (80.2% very satisfied and 18.4% satisfied).

We report the first genetically confirmed case of ATTRv mimicking amyotrophic lateral sclerosis (ALS) in Saudi Arabia. A 47-year-old male presented with progressive right-sided limb weakness (proximal > distal) and dysarthria over 18\u00a0months. Neurological examination revealed fasciculations, distal atrophy, and brisk reflexes with normal muscle tone and no spasticity. Electrophysiological studies demonstrated a length-dependent sensorimotor axonal neuropathy with widespread denervation changes involving bulbar, cervical, and lumbosacral regions. Brain and spine MRI, along with whole-body CT, excluded structural or paraneoplastic causes. Genetic testing identified a pathogenic heterozygous variant in the TTR gene: NM_000371.4:c.424G\u00a0>\u00a0A (p.Val142Ile). Transthoracic echocardiography revealed mild concentric left ventricular hypertrophy. There was no clinical evidence of autonomic, renal, or ocular involvement. This case underscores the importance of considering ATTRv in patients presenting with atypical MND, particularly when clinically significant sensory symptoms, absent upper motor neuron signs, or unexplained cardiac abnormalities are present.

These advances have been demonstrated in individuals who are still able to vocalize and move speech articulators. Here, we decoded intended speech from an individual with long-standing anarthria, locked-in syndrome, and ventilator dependence due to advanced symptoms of ALS. We found that phonemes, words, and higher order language units could be decoded well above chance. While sentence decoding accuracy was below that of demonstrations in participants with dysarthria, we attained an extensive characterization of neural signals underlying speech in a person with locked-in syndrome and identify directions for future improvement. These include closed-loop speech imagery training and decoding linguistic (rather than phonemic) units from neural signals in middle precentral gyrus to augment decoding at the sentence level. These results demonstrate that usable speech decoding from motor cortex may be feasible in people with anarthria and ventilator dependence.",

We tracked signal characteristics and decoding over 25 months in a participant with ALS to determine how high-gamma (HG, 70-170 Hz) activity changes over time and whether these changes affect offline speech decoding. We implanted two 8\u00d78 subdural ECoG grids over left sensorimotor cortex (SMC) in a participant with slowly progressive bulbar variant ALS. Across 25 months, the participant performed an overt syllable-repetition task (12 consonant-vowel tokens) during simultaneous ECoG and audio recording. We quantified HG activation ratio (ActR), spectral signal-to-noise ratio (SNR; HG/HF, where HF = 300-499 Hz), and peak z-scored HG responses. Speech acoustics were evaluated using first/second formants (F1/F2) and the triangular vowel space area (tVSA). Offline EEGNet-based decoders were assessed in two stages: models trained on post-implant months 1-6 were tested on months 7-25, while models trained on stabilized data (months 7-11) were tested on the remaining period (months 12-25). Electrode-level saliency assessed spatial contributions to decoding. Acoustic analyses showed a significant reduction in tVSA over two years (-44.6 Hz2/day; P < 10-7), consistent with mild intelligibility decline. Neural metrics (ActR and SNR) followed a biphasic trajectory: increasing during the first 6 months, after which ActR stabilized (0.041%/day; P = 0.13), and SNR declined gradually (-0.46%/day, P < 10- 4). The model trained on months 1-6 achieved 55.7% accuracy (chance: 8.33%), but performance declined over time (-0.019%/day; P = 2.1\u00d710-4). Conversely, the model trained on months 7-11 achieved higher accuracy (65.9%) on subsequent data with no significant temporal decline (P = 0.23). Speech-related HG features exhibited an initial unstable period followed by a long-term gradual SNR reduction, potentially reflecting disease progression. Models trained after signal stabilization generalized robustly to data recorded over a year later. These findings confirm that despite reduced absolute HG power and mild acoustic degradation of speech, cortical features remain stable enough to support durable ECoG speech BCIs without frequent recalibration. These findings will motivate future adaptive calibration algorithms that account for slow signal changes while leveraging stable spatial representations in ventral SMC. NCT03567213.",

To manage these symptoms, speech & language therapists (SLTs) must identify relevant speech and swallow outcomes and select suitable outcome measurement instruments. Remote monitoring is an evolving mode of health status tracking. This survey aimed to establish SLT perspectives on ALS assessment regarding 1) the clinical meaningfulness of existing outcome measurement instruments 2) remote monitoring 3) usefulness of assessment devices for patient care and 4) bulbar function outcomes and measurement instruments useful for research studies. An online English-language survey was distributed internationally through gatekeepers and social media. Sixty-six SLTs responded from 13 countries. Current outcome measurement instruments were regarded as clinically meaningful in ALS by 35% for speech and 41% for swallow. Only 12% had access to remote monitoring, but 77% would like to avail of it, with 58% perceiving its potential to enhance care. Eighty-two percent deemed remote monitoring using digital patient-reported outcome measures (PROMs) useful. Speech intelligibility measurement was selected as the most useful communication outcome for remote monitoring (92%) and research (94%). SLTs agreed that speech intelligibility test software (72%), smart device apps (70%) and tongue pressure measurement devices (54%) are useful assessment equipment. SLTs want better measurement instruments for speech and swallow in ALS. They regarded technologies including remote monitoring incorporating digital PROMs as useful. Outcomes reflecting communication and swallow functional success level were deemed most useful. These survey findings can inform the selection of digital speech and swallow outcomes for ALS.",

The sEMG features were clustered into 10 interpretable composite measures and validated by evaluating their (1) internal consistency using Cronbach's \u03b1 ; (2) associations with standardized functional outcomes and a biomechanical metric-stiffness-via mediation analysis; (3) discriminatory efficacy in distinguishing ALS+B and ALS-B from HC, as well as from each other, using machine learning classifications; and (4) robustness to common nonmotor confounders, including age, sex, and cognitive-linguistic impairments, through a comparison of discriminatory performance before and after adjustment for these factors. All composite measures exhibited (1) high internal consistency (Cronbach's \u03b1 = 0.89 \u00b1 0.071 ), (2) significant (or marginally significant) direct or stiffness-mediated indirect associations with the functional outcomes, and (3) consistently high discriminatory accuracy (0.82-0.85), both before and after adjustment for confounders. The sEMG framework demonstrates strong potential as a reliable, valid, and robust objective tool to detect subclinical neuromuscular changes throughout the prodromal and symptomatic phases of bulbar involvement in ALS, while remaining resistant against disease-related cognitive-linguistic impairments and disease-unrelated confounders. This tool may augment standard clinical evaluations, enabling earlier detection of bulbar involvement and measurement-based care in ALS.",

Increasing evidence implicates immune changes and inflammation in some ALS patients. Several studies demonstrated that ALS coexists with CIDP or polyneuropathy. Mouse models of C9orf72 loss-of-function mutations exhibit fatal immune dysregulation. A 62-year-old Caucasian man developed right foot drop, and he underwent fibular nerve release without significant improvement. At the same time, he developed progressive weakness and numbness in his bilateral hands. MRI revealed cervical canal stenosis and neuroforaminal narrowing that prompted neurosurgical decompression without clinical improvement. Subsequently, he developed left foot drop. At the clinic presentation, he exhibited dysarthria, tongue fasciculations, weakness in all extremities, muscle atrophy, widespread fasciculations, and upper extremity hyperreflexia, meeting clinical criteria for ALS. Genetic testing identified a pathogenic variant in the C9orf72 gene, confirming a C9orf72 variant, commonly linked to familial ALS. Brain MRI demonstrated the motor band sign. Although EMG/NCS findings were consistent with lower motor neuron disease, he also had signs of demyelinating polyneuropathy based on conduction parameters. Neuromuscular ultrasound showed significant multifocal nerve enlargement typical of immune-mediated neuropathy. CSF studies revealed albuminocytologic dissociation (protein: 112\u202fmg/dL, with normal cell count) and high albumin quotient and index. He fulfilled the 2021 EAN/PNS criteria for possible typical CIDP. He was treated with intravenous immunoglobulin in addition to riluzole with temporary improvement. This is the first case of the co-existence of CIDP and ALS in the setting of a pathogenic C9orf72 variant.",

We extend the work of Macrae (2017), who identified variability in stimulus items across consonant singletons, consonant clusters, vowels, phoneme complexity, and bound morpheme. This study sought to augment that work with a deeper analysis of lexical and sublexical features of these stimuli. The stimuli from 12 articulation and/or phonological tests were extracted, resulting in 667 stimuli. All stimuli were run through a phonological neighborhood density and phonotactic probability calculator. Word frequency was determined using Moe et al.'s (1982) database. Means and ranges for all lexical characteristics were computed across each of the 12 tests. Most stimuli were from sparse phonological neighborhoods, and included common sound sequences. Although the average word frequency value was in the high range, overall, very few test stimuli were high-frequency words. There was not one articulation and/or phonological test that considered or balanced these three lexical properties. We discuss the linguistic constraints surrounding developing such a test. We also discuss future research opportunities to examine if these lexical properties may result in over- and underidentification of children with speech sound disorders.",

One hundred and thirteen consecutive ALS patients underwent comprehensive dysphagia evaluation with fiberoptic endoscopic evaluation of swallowing (FEES) and were classified according to DOSS. Safe and unsafe swallowing were defined by DOSS levels 7-6 and 5-1, respectively. Patient-reported measures included ALS Functional Rating Scale-Revised swallow item (I-3) and Eating Assessment Tool-10 (EAT-10). Non-instrumental clinical measures were hyolaryngeal excursion, voluntary cough (VC), voice quality and reflexive cough/throat clearing (VRC), and maximum phonation time (MPT). Inter- and intra-rater reliability were assessed using weighted Cohen's kappa and Fleiss' kappa coefficients. Non-instrumental measures diagnostic performance was evaluated using receiver operating characteristic (ROC) curve analysis. Twenty-six of 113 patients (23%) exhibited an unsafe swallowing. Inter- and intra-rater agreement for DOSS classification was excellent across raters. EAT-10 and a composite clinical index derived from VC, VRC, and MPT showed the highest diagnostic accuracy with area under the curve values of 0.790 and 0.832, respectively. Other non-instrumental measures demonstrated lower discriminative performance. The DOSS showed an excellent reliability when applied to FEES in patients with ALS, supporting its use as a functional classification tool with direct nutritional and management implications. Non-instrumental measures should be interpreted with caution and confined to a triage role rather than diagnostic decision-making, particularly in light of the rapid progression of dysphagia in ALS.",

Recordings of sequential motion rates were collected from 231 subjects, including 80 healthy controls and 151 patients with neurological diseases such as amyotrophic lateral sclerosis, essential tremor, Huntington's disease, multiple sclerosis, multiple system atrophy, Parkinson's disease, progressive supranuclear palsy, and cerebellar ataxia. A robust automatic segmentation algorithm utilizing convolutional neural networks and rule-based postprocessing was developed and evaluated across disease type, dysarthria type, and dysarthria severity. The performance of the developed artificial intelligence-based algorithm was compared with a traditional signal processing-based segmentation approach. Our deep learning-based algorithm was able to correctly identify the position of individual syllables with a very high F1 score of 99.1%, compared to a signal processing-based approach with an F1 score of 97.7%. Using a 10-ms tolerance window, the deep learning-based algorithm achieved an average accuracy of 92.0% for the temporal detection of individual phoneme positions. Performance was strongly influenced by dysarthria severity, with accuracy reaching 94.7% in mild, 91.0% in moderate, and 83.1% in severe dysarthria. Disease and dysarthria type did not appear to have a substantial effect on algorithm performance. Our proposed deep learning-based algorithm provides reliable segmentation of syllable and individual phoneme positions during oral diadochokinesis across various disease types, dysarthria types, and dysarthria severities. The deep learning-based segmentation approaches have the potential to outperform the traditional signal processing methods for assessing oral diadochokinesis.",
        "42113599": "ID: 42113599\nTitle: Amyotrophic Lateral Sclerosis: A Review.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive weakness due to degeneration of upper motor neurons in the brain and lower motor neurons in the brainstem and spinal cord. It affects approximately 25\u202f000 individuals in the United States. Amyotrophic lateral sclerosis is characterized by progressive painless muscle weakness that typically begins in a focal region of the body, such as limb muscle weakness causing hand weakness or foot drop (65%), cranial muscle weakness causing speech or swallowing problems (20%-25%), or axial muscle weakness causing bent posture (5%-10%), and spreads to other body regions over time. The disease usually manifests with dysfunction indicative of both upper motor neurons (causing muscle stiffness and spasticity) and lower motor neurons (causing weakness, fasciculations, atrophy, and flaccidity). After onset, weakness spreads through the musculature and typically causes death due to respiratory muscle weakness. Among people with ALS, approximately 85% have sporadic ALS, which is not associated with known environmental or genetic factors, and 15% have familial ALS. Amyotrophic lateral sclerosis is diagnosed based on clinical features, which can be supported by results of electromyography. More than 60 genes have been associated with ALS, and most are autosomal dominant. Pathogenic variants in chromosome 9 open reading frame 72 (C9orf72) are found in 40% of all familial ALS cases, and pathogenic variants in superoxide dismutase 1 (SOD1) are found in 20% of patients with familial ALS. Patients with ALS survive a mean of 3 to 5 years after diagnosis, and there are currently no curative therapies. Clinical care primarily focuses on symptom management and quality of life. Three US Food and Drug Administration (FDA)-approved disease-modifying therapies are available in the United States. Riluzole and edaravone are oral medications that slow ALS progression by up to 2 to 4 months, and tofersen is an intrathecally administered gene therapy for patients with SOD1 gene variants. Specialized multidisciplinary teams, comprising neurologists, nurses, therapists, dietitians, and social workers, are associated with improved survival (4-7 months) and quality of life. Amyotrophic lateral sclerosis is a progressive and fatal neurodegenerative disorder of upper and lower motor neurons. No curative therapies exist. Two oral medications, riluzole and edaravone, are approved by the FDA and modestly decrease disease progression in sporadic ALS. Tofersen, an intrathecally administered gene-based therapy, is also FDA approved and slows disease progression in patients with SOD1 pathogenic gene variants.",

This study aimed to evaluate the sensitivity of LTAS descriptors in a broad range of neurological diseases and various types and severities of dysarthria. Four spectral moments of spectral mean, spectral standard deviation, spectral skewness and spectral kurtosis based on LTAS were computed for reading passage collected from 461 speakers, including 306 healthy controls and 155 neurological patients secondary to Parkinson's disease (PD), progressive supranuclear palsy, multiple system atrophy (MSA), Huntington's disease, essential tremor, cerebellar ataxia (CA), multiple sclerosis (MS), and amyotrophic lateral sclerosis. Compared to controls, the spectral mean was significantly lower in PD and MS while elevated in CA. Significantly changed LTAS features were observed only in hypokinetic dysarthria and in mixed dysarthrias manifesting hypokinetic elements. Although LTAS features differed between controls and patients with varying degrees of dysarthria, there was no progressive increase in dysarthria severity. Our findings suggest that LTAS-based speech analysis may provide valuable cues to aid differential diagnosis among neurological diseases with overlapping clinical features. LTAS appears more informative when applied to specific diseases than to pooled dysarthria types arising from diverse neurological etiologies.",

Effective management of progressive communication disorders requires a personalized approach to deliver timely interventions tailored to the evolving profiles of communicative impairment, thereby supporting functional communication throughout the disease course. To this end, reliable tools capable of detecting and quantifying both disease-specific patterns of communicative impairment and within-disease phenotypic variability are urgently needed. This study leverages Artificial Intelligence and advanced data analytics to develop an acoustic-based framework for automated extraction of interpretable, clinically grounded speech markers to enable objective assessment and phenotyping of progressive communication disorders. Three groups of participants, including 14 individuals with amyotrophic lateral sclerosis (ALS) and 15 individuals with Parkinson's disease (PD), alongside 10 neurologically healthy controls, performed a standardized oral passage reading task, yielding 739 speech samples. Fifty acoustic features were extracted using an automated analytic pipeline and subsequently clustered into six interpretable composite markers. The clinical utility of these markers was evaluated with the recorded speech samples by examining their (1) associations with standardized metrics of cognitive, motor speech, and overall communicative functions, (2) efficacy for detecting and differentiating disease-specific communicative impairment patterns in ALS and PD using supervised machine learning, and (3) utility for within-disease phenotyping and stratification using unsupervised clustering analysis. The markers effectively (1) detected subtle subclinical changes across multiple domains prior to substantial declines in functional communication outcomes; (2) differentiated disease-specific patterns of communicative impairment (multiclass area under the curve > 0.90); and (3) identified subgroups with distinct speech profiles within each disease. The findings support the potential of the proposed framework as a clinically translatable, objective tool to facilitate early detection, differential diagnosis, and phenotyping of progressive communication disorders, ultimately advancing personalized, measurement-based care in neurodegenerative diseases.",

A cross-sectional survey assessing pwALS' perceptions of SLPs was distributed from October 2024 to January 2025 through electronic mailing lists of relevant professional organizations. A questionnaire examined pwALS' understanding of the SLP role, satisfaction levels, alignment between patient-reported impairments and SLP interventions, and perceived gaps in care. Responses were analyzed using descriptive statistics, with open-ended items analyzed using qualitative analysis. The 81 survey respondents consisted of pwALS (81.5%), caregivers (11.1%), family members (4.9%), and others (2.5%). Overall satisfaction with SLP care was high, though open-ended responses revealed gaps in understanding. Many were unaware of the full scope of SLP services; only 17.3% recognized cognitive evaluation and 8.6% cognitive therapy, compared with speech (77.8%) and swallowing (81.5%) evaluations. Reported services often did not align with communication and swallowing needs, but patients educated about a service were significantly more likely to use it. Overall satisfaction with SLP care was high; however, open-ended responses revealed gaps in understanding, unmet needs, and limited awareness of the full scope of SLP services. This misalignment highlights the need for improved patient and caregiver education regarding the role and timing of SLP involvement to enhance engagement, appropriate service use, and outcomes in ALS care.",

This study aims to evaluate the effectiveness of A Successful Swallowing with Effortful Training (ASSET) program, included in the 'The 365 Healthy Swallow Health Coach application' in preserving speech and swallowing abilities in ALS patients through self-training. In this 8-week quasi-experimental study, 13 participants were allocated to either the app-guided ASSET training group (n=7; three sessions per day, five days per week) or a usual-care control group (n=6) based on their clinical visit schedules. To evaluate changes over time and compare the two groups, linear mixed models were employed. Changes in ALS severity scale (ALSSS), Diadochokinetic (DDK) task, speech intensity, Speech Handicap Index-15, Dysphagia Handicap Index, Swallowing Quality of Life (SWAL-QOL), and Brief Inventory of Swallowing Assessment-15 were assessed. ALSSS speech scores was relatively preserved from 5.43 (95% CI 3.01-7.84) to 5.29 (95% CI 2.87-7.70) in the ASSET treatment group, but declined from 6.33 (95% CI 3.73-8.94) to 4.83 (95% CI 2.23-7.44) in the control group, with a significant group-by-time interaction (p=.017). DDK/tuh/and/kuh/were relatively preserved from 11.86 to 11.71 and from 12.29 to 11.57 respectively in ASSET group, but declined from 11.67 to 7.50 and from 11.83 to 7.17 in the control group, with significant interactions in/tuh/(p=.032) and/kuh/(p=.044).

Both disorders affect voice production through different physiological mechanisms, yet neither condition has a widely adopted objective biomarker for routine clinical use. Voice analysis has emerged as a non-invasive digital biomarker candidate, but existing studies have largely focused on binary classification within a single disorder or language. This study aimed to evaluate whether an unified multiclass machine learning (ML) framework applied to sustained vowel \"a\" phonation can discriminate between PD, COPD, and healthy controls (HC) across linguistically distinct cohorts. Sustained vowel recordings were analyzed from Swedish speaking individuals with COPD and HC, and English-speaking individuals with PD and HC, collected under comparable mobile recording conditions. Acoustic features included baseline voice measures and Mel Frequency Cepstral Coefficients. A soft voting ML framework integrating support vector machine, random forest, CatBoost, and light gradient boosting classifiers was trained using nested cross validation with hyperparameter optimization. Data were partitioned at the participant level into a development cohort and an independent test cohort. Model performance was evaluated using accuracy, macro averaged precision, recall, F1 score, receiver operating characteristic analysis, and confusion matrices. Model interpretability was assessed using Shapley additive explanations and vowel space analysis. The final soft voting classifier achieved robust multiclass discrimination on the participant disjoint independent test set, with an overall accuracy of 0.842 and a macro averaged F1 score of 0.839. Classification performance differed across groups, with the highest performance observed for PD, intermediate performance for HC, and lower performance for COPD. Misclassifications occurred primarily between HC and COPD, while confusion between PD and COPD was minimal. Feature attribution analysis revealed class dependent relevance patterns, and vowel space analysis demonstrated subtle but consistent group level differences. These findings demonstrate the feasibility of using an explainable soft voting machine learning framework applied to sustained vowel phonation to distinguish between neurologically and respiratory driven voice impairments across linguistic contexts. The study supports voice as a promising digital biomarker modality for multiclass clinical discrimination using mobile recordings.",

This study evaluates the performance of various deep-learning models in classifying speech recordings from individuals with normal cognition (NC), MCI, and AD, to identify the most effective approach for audio-based cognitive impairment diagnosis. Speech data were obtained from the AI Hub \"Cognitive Impairment Diagnosis Voice/Conversation\" dataset. The study analyzed voice recordings from 320 female participants (105 with Alzheimer's disease, 92 with mild cognitive impairment, and 123 cognitively normal controls). Three deep-learning architectures were compared: a one-dimensional convolutional neural network (1D CNN), an audio spectrogram transformer (AST), and a speech recognition model (Wav2Vec 2.0). The models were trained using features such as spectrograms, mel-spectrograms, and mel-frequency cepstral coefficients (MFCCs). Model performance was assessed using accuracy, recall, precision, and F1-score, with a five-fold cross-validation strategy to ensure robust and unbiased evaluation. Statistical significance was assessed using pairwise proportion z-tests with Holm-Bonferroni correction, and Wilson score 95% confidence intervals were computed for each model's accuracy. Wav2Vec 2.0 outperformed the other models, achieving the highest accuracy and F1-scores for NC vs. MCI (accuracy: 0.74, F1: 0.72) and NC vs. AD (accuracy: 0.83, F1: 0.83). Pairwise proportion z-tests with Holm-Bonferroni correction confirmed that Wav2Vec 2.0 significantly outperformed 7 of 10 competing models (corrected p\u2009<\u20090.05) in both classification tasks. Performance varied by model and classification task, with Wav2Vec 2.0 consistently demonstrating superior accuracy across labels. This study emphasizes the importance of selecting appropriate models and features for task-specific optimization and provides a foundation for developing non-invasive, speech-based diagnostic tools for cognitive disorders.",

We aimed to characterize the clinical phenotype, upper motor neurone (UMN) sign prevalence, survival, and functional milestones. We retrospectively analyzed 78 patients with ALS8 confirmed via molecular testing or familial linkage analysis from 57 apparently unrelated families. UMN signs were assessed using a five-item composite of pyramidal signs. Survival and milestones were estimated using Kaplan-Meier analysis. Median age at onset was 44.9\u2009years; 51% were men. Onset was lumbar in 94%, proximally predominant. UMN signs were present in 53 patients; none exhibited clonus. At admission, 51% had spinal-onset ALS, 42% progressive muscular atrophy (PMA) and 6% flail leg; 30% of patients with PMA subsequently developed UMN signs. Survival was 21.9\u2009years; times to wheelchair dependence and noninvasive ventilation were 7.0 and 10.0\u2009years, respectively. Bulbar involvement occurred in 17 (21.8%) patients, predominantly as dysphonia. UMN status did not affect survival (p\u2009=\u20090.312). The standardized mortality ratio was 4.54 (95% CI 2.77-7.01), supporting disease-related excess mortality. ALS8 is a slowly progressive motor neurone disease with lumbar onset, ascending progression, and frequent but subtle UMN signs. Survival was markedly prolonged but functional decline followed a predictable sequence. These findings expand the phenotypic characterization of ALS8 and support genetic counseling and anticipatory management.",

We assess past, current, and emerging trends in the prevalence and burden of mental disorders across sexes and age groups, for 21 regions, 204 countries and territories, and by Socio-demographic Index (SDI) quintile, from 1990 to 2023. Mental disorders included in GBD 2023 were anxiety disorders, major depressive disorder, dysthymia, bipolar disorder, schizophrenia, autism spectrum disorders, conduct disorder, attention-deficit hyperactivity disorder, anorexia nervosa, bulimia nervosa, idiopathic developmental intellectual disability, and a residual category of other mental disorders. A literature review identified epidemiological data for each disorder. These were analysed via a Bayesian meta-regression to estimate prevalence by disorder, sex, age, location, and year. Disorder-specific prevalence was multiplied by disability weights representing the severity of health loss associated with each disorder to estimate years lived with disability (YLDs). Deaths due to anorexia nervosa were assessed with a Cause of Death Ensemble modelling strategy to estimate deaths by sex, age, location, and year, and then multiplied by the standard life expectancy at age of death to estimate years of life lost (YLLs). YLDs equalled disability-adjusted life-years (DALYs) for all mental disorders except anorexia nervosa (the only mental disorder considered as an underlying cause of death in GBD), for which DALYs represented the sum of YLDs and YLLs. We presented prevalence, deaths, YLDs, YLLs, and DALYs as counts, age-specific rates per 100\u2008000 population, and age-standardised rates per 100\u2008000 population. We estimated 1\u00b717 billion (95% uncertainty interval 1\u00b706-1\u00b731) prevalent cases of mental disorders globally in 2023, equivalent to an age-standardised prevalence rate of 14\u2008210\u00b77 cases (12\u2008849\u00b75-15\u2008940\u00b71) per 100\u2008000 population. These estimates represented a 95\u00b75% (75\u00b70-121\u00b72) increase in prevalent cases and 24\u00b72% (11\u00b74-41\u00b74) increase in age-standardised prevalence rate between 1990 and 2023. All mental disorders showed increases in prevalent cases between 1990 and 2023, while notable increases were seen in age-standardised prevalence rates for anxiety disorders, major depressive disorder, dysthymia, anorexia nervosa, bulimia nervosa, schizophrenia, and conduct disorder. There were an estimated 171 million (127-228) DALYs due to mental disorders globally across sex and age in 2023, equivalent to an age-standardised DALY rate of 2070\u00b75 DALYs (1519\u00b71-2750\u00b75) per 100\u2008000 population. Mental disorders contributed to 6\u00b71% (4\u00b78-7\u00b76) of all-cause DALYs in 2023, making them the fifth leading cause of global DALYs (up from 12th in 1990). DALYs were almost entirely composed of YLDs. Mental disorders were the leading cause of YLDs in 2023 (up from second in 1990), explaining 17\u00b73% (14\u00b78-20\u00b76) of all-cause global YLDs. Leading causes of mental disorder DALYs were anxiety disorders (ranked 11th among the 304 diseases and injuries at Level 4 of the GBD cause hierarchy), major depressive disorder (15th), and schizophrenia (41st). Globally in 2023, mental disorder age-standardised DALY rates were higher among females (2239\u00b76 [1643\u00b77-3014\u00b71] per 100\u2008000) than among males (1900\u00b72 [1399\u00b78-2510\u00b78] per 100\u2008000), and peaked in the 15-19 years age group (2617\u00b73 [1850\u00b76-3696\u00b78] per 100\u2008000). All locations showed increased mental disorder DALY rates in 2023 compared with 1990, ranging across countries and territories from 1302\u00b74 (952\u00b77-1683\u00b77) per 100\u2008000 in Viet Nam to 3555\u00b78 (2661\u00b79-4715\u00b70) per 100\u2008000 in the Netherlands. Across SDI quintiles, DALY rates ranged from 1853\u00b70 (1352\u00b71-2469\u00b73) per 100\u2008000 for middle SDI to 2184\u00b71 (1606\u00b71-2890\u00b73) per 100\u2008000 for high SDI. A significant health burden was imposed by mental disorders in all countries and territories in 2023, irrespective of the health resources available. In some instances, this burden has increased over time and is unevenly distributed across populations. Stronger surveillance systems, particularly in low-income and middle-income countries, are required. Additionally, we need more coordinated and inclusive policies to reduce the burden through early treatment and prevention, tailored to sex and age differences across locations. Responding to the mental health needs of our global population, especially those most vulnerable, is an obligation, not a choice. Gates Foundation, Queensland Health, and University of Queensland.",
        "42168009": "ID: 42168009\nTitle: Primary Lateral Sclerosis French National Diagnostic and Care Protocol.\nAbstract: Primary lateral sclerosis (PLS) is a rare neurodegenerative motor neuron disease characterized by progressive and selective involvement of the central motor neuron within the bulbar and spinal regions. It is estimated to account for 1-5% of motor neuron diseases and typically presents in the fifth or sixth decade of life, with a slight male predominance. According to current consensus criteria, the diagnosis relies on the demonstration of progressive upper motor neuron dysfunction in the absence of lower motor neuron involvement, with persistence of isolated upper motor neuron signs for at least four years in order to exclude a slowly progressive upper motor neuron-predominant form of amyotrophic lateral sclerosis (ALS). The French Motor Neuron Disease Network (FILSLAN) developed a National Diagnostic and Care Protocol (PNDS) with the aim of standardizing diagnostic criteria, optimizing differential diagnosis, and providing evidence-based recommendations for therapeutic management and follow-up across the national territory. These recommendations were elaborated in accordance with the methodological framework of the French National Authority for Health for rare diseases. The protocol provides practical guidance for establishing PLS as a diagnosis of exclusion, distinguishing it from ALS and hereditary spastic paraplegias, and organizing appropriate clinical and paraclinical investigations. It also outlines indications for genetic testing in selected cases and defines a multidisciplinary management strategy centered on symptomatic treatment, early rehabilitation, respiratory and nutritional surveillance, and psychosocial support. Given the slower progression of PLS compared with ALS, biannual multidisciplinary follow-up is generally appropriate. This protocol aims to harmonize clinical practice and improve patient care while acknowledging the current absence of disease-modifying therapies.",

Current clinical scales are rater-dependent and time-consuming, while neuroimaging is costly and inaccessible. We aim to develop and validate a novel Speech Index, derived from automated acoustic analysis, to stratify HD stages and predict the severity of disease. We recruited 141 HTT gene carriers (37 premanifest, 104 manifest HD) and 69 healthy controls. Participants read a standardized passage, and the recordings were processed to extract 28 speech features. A composite Speech Index was constructed using Bootstrap LASSO Regression for feature selection. Its performance was validated against the HD stages, clinical scale scores and the volume of the caudate and putamen from MRI. The Speech Index significantly increased across HD stages (p\u2009<\u20090.001). The Index showed strong correlations with clinical measures (cUHDRS: \u03c1\u2009=\u2009-0.67; TMS: \u03c1\u2009=\u20090.57; SDMT: \u03c1\u2009=\u2009-0.63; all p\u2009<\u20090.001) and neuroimaging biomarkers (caudate: \u03c1\u2009=\u2009-0.55; putamen: \u03c1\u2009=\u2009-0.62; all p\u2009<\u20090.001). Generalized additive models confirmed the Index's high predictive value for these outcomes (pseudo-R2 from 0.430 to 0.596). We developed a fully automated, interpretable Speech Index that serves as a valid digital biomarker for HD severity. It holds promise for remote monitoring, clinical trial enrichment, and objective assessment of therapeutic efficacy.",

There is an urgent need to investigate the impact of this multiparametric alteration on patients' lives. Therefore, the COMunication and ATAXia measure (COMATAX) was developed and validated in French and German. In the PROFA study (NCT05943002), we conducted focus groups and cognitive interviews with patients with FA, professionals and caregivers to elaborate relevant items of communication disabilities. Subsequently, the measure was validated in 93 patients with FA via a mobile health app. For validation, distribution properties, reliability (Cronbach's alpha) and validity (correlations with VHI-30, SSQ-12, SARA total score, SARA speech item, Speech rate and GAA repeats; known-groups validity by age, sex, and self-rated health/wellbeing, disease-severity, hearing function, daily activities, and exploratory factor analysis) were calculated. An IRT analysis was performed to assess item characteristics. COMATAX consists of 17 items (five response options each) and an 18th question asking about the most bothersome symptom. We observed high internal consistency for the total COMATAX scale (\u03b1\u2009=\u20090.897), strong correlations with VHI-30 (r=.894), SSQ-12 (r\u2009=\u2009-.531), moderate with SARA score (r=.498), SARA speech item (r=.416), Speech rate (r=-.354), weak with GAA repeat length (rGAA1=-0.207) and the ability to distinguish between different subgroups (disease severity, self-rated health, wellbeing, hearing function, and daily activities). Most items showed good discrimination of communication ability. The COMATAX is a valid and reliable patient-reported communication disability measure, useful in future therapeutic trials in FA.",

In this paper, we introduce a data-driven approach to support the characterization of ALS phenotypes based on clinical data from a battery of examinations. A consensus clustering method is proposed to identify stable clusters across multiple random data sub-samples, with the objective of discovering whether the retrieved patients' groups and related features align with clinical phenotypes and medical knowledge.

The purpose of this study was to engage with Black and Hispanic communities about interest in and support needed for memory screening. Participants were recruited from established community partners of the South Texas Alzheimer's Disease Research Center to engagein a 90-minute listening session. The session was recorded with participants' permission, and a thematic analysis was conducted by 2 independent coders. Sixteen individuals (81% female, 88% Hispanic or Black) from various perspectives participated (eg, health care workers, persons with dementia, caregivers). Four core themes emerged: building trust, access and time barriers, community-specific literature, and representative messengers. Trust was noted to be foundational, encompassing who delivers the screening and where it takes place. Transportation, time burden, competing caregiving responsibilities, work schedules, and limited access to technology/internet were key barriers. The need to create accessible and relatable literature and videos tailored to diverse educational levels and cultural backgrounds was also emphasized. Trusted members of the community could be accepted to perform memory screenings and provide education. Partnering with faith-based organizations, senior centers, and other community hubs would help overcome barriers to screening.",

Creatinine (Cre) reflects muscle mass, whereas cystatin C (CysC) may reflect neurodegeneration without being directly influenced by muscle mass; however, both have limitations. We aimed to investigate whether the creatinine-to-cystatin C ratio (Cre/CysC) was cross-sectionally associated with functional status in patients with ALS. We retrospectively analyzed 30 patients diagnosed with ALS at the National Organization Hospital Okinawa Hospital between 2021 and 2024. Baseline ALS Functional Rating Scale-Revised (ALSFRS-R) scores and serum Cre and CysC levels were recorded. Associations with the ALSFRS-R were assessed using Spearman's correlation, with subgroup analyses by sex, site of onset, age at diagnosis, body mass index (BMI), and diagnostic delay. Multivariable analyses were performed to examine the independent association between Cre/CysC and ALSFRS-R while accounting for relevant clinical covariates. Cre/CysC showed a stronger cross-sectional correlation with ALSFRS-R (rs=0.648, p\u2009=\u20090.0001) than Cre alone (rs =0.427) or CysC (rs =-0.119). Exploratory subgroup analyses showed generally positive associations in several subgroups, although no statistically significant association was observed in the small bulbar-onset subgroup. In multivariable analysis adjusted for age at onset and diagnostic delay, Cre/CysC remained independently associated with ALSFRS-R (\u03b2\u2009=\u200920.1, 95% CI 6.41-33.9, p\u2009=\u20090.006). Given the small sample size and cross-sectional design, these findings should be interpreted as exploratory. Cre/CysC showed a stronger cross-sectional association with functional status than either marker alone. Because it is derived from routine laboratory tests, Cre/CysC may represent a simple exploratory measure associated with functional status in ALS. However, the present findings do not establish prognostic utility or fully account for disease stage and biological heterogeneity. Prospective longitudinal studies incorporating disease progression measures and broader clinical and genetic characterization are warranted.",

We developed a non-verbal dichotic listening test (NVDLT) based on everyday sounds, and compared this with a standard verbal dichotic listening test (VDLT) in 36 people with primary progressive aphasia (PPA), 18 with typical AD (tAD), 6 with right temporal-variant frontotemporal dementia (rtvFTD), and 29 cognitively-healthy controls. Daily-life hearing function was assessed using the modified Amsterdam Inventory for Auditory Disability and Handicap (mAIAD). On NVDLT, all dementia groups except rtvFTD performed worse than controls; tAD, logopenic-variant PPA and nonfluent/agrammatic-variant PPA performed worse than rtvFTD. NVDLT performance predicted atrophy in the retrosplenial cortex and hippocampus. NVDLT score discriminated tAD patients from controls with near-perfect accuracy (area under the curve [AUC]\u00a0=\u00a00.99) and predicted daily-life hearing function (r\u00a0=\u00a00.57).

However, standard manual counting or inadequate clinical monitoring often fails to provide reliable measurements. This study evaluated and validated the PneumoWave biosensor for respiratory rate measurement across a broad physiological range and different body postures (45\u00b0, 90\u00b0, and 180\u00b0) in both in vitro and in vivo settings. In vitro validation was performed using a SimMan ALS manikin operated at respiratory settings of 6-30 breaths per minute, with 10 s periods of simulated apnea. In vivo validation involved 20 healthy volunteers performing metronome-guided breathing while wearing bilateral PneumoWave biosensors. In vitro results demonstrated an excellent correlation between biosensors and manikin respiratory settings and captured all apnea events (r = 0.99, ICC = 0.99). In vivo findings showed good agreement with direct observational count (r = 0.99, R2 = 0.99, ICC = 0.99), with 97% of apnea events captured by both devices in all positions. Body postures had no significant impact on biosensor accuracy.

A cross-sectional sample of 100 individuals, including patients with ALS\u00a0and individuals with nonneurological dysphonia, was analyzed. Sustained vowel phonation was recorded and characterized using 26 variables, including standard acoustic measures (fundamental frequency -fo-, jitter, shimmer, and harmonics-to-noise ratio (HNR)) and 22 biomechanical parameters. Principal component analysis\u00a0was applied to investigate relationships among variables and reduce dimensionality. Unsupervised clustering was performed at both the variable level to identify functional groupings and the participant level to derive data-driven voice profiles. Cluster validity was assessed using internal indices. Post hoc statistical comparisons and chi-square tests were used descriptively to characterize between-cluster differences and their relationship with clinical categories. The first five principal components explained 70.7% of the total variance, revealing structured relationships between acoustic and biomechanical features. Participant level clustering consistently supported a two-profile solution. Fifteen voice parameters differed significantly between profiles after false discovery rate correction, with the largest effects observed for shimmer, HNR, and the biomechanical parameter Pr11, reflecting differences in vocal stability and noise-related characteristics. The identified profiles were not significantly associated with clinical diagnostic categories. An unsupervised multimodal analysis of sustained phonation revealed two coherent vocal profiles that transcend traditional diagnostic labels. These data-driven voice phenotypes may capture functional patterns of voice production and support future efforts toward more refined and personalized characterization of voice disorders.",

ALS typically progresses rapidly, leading to respiratory failure within 3 to 5 years of symptom onset. Identifying risk factors that influence disease progression and survival is critical for enhancing management strategies. The present study therefore investigated the roles of inflammatory factors and adipokines (especially adiponectin) in the progression and prognosis of ALS.\u00a0The study included 80 ALS patients, with a follow-up period of 1.5 years. Survival analysis was performed using a Cox regression, with hazard ratios (HR) and 95% confidence intervals (CI) presented via forest plots. Our results indicated that ALS patients in the fast-progressing group exhibited lower levels of adiponectin (p\u2009<\u20090.001) and IL-10 (p\u2009<\u20090.001).

Typically, the disease progresses over several months, and death from respiratory failure occurs within 2-5\u2009years of onset. As we highlight in this Review, data on MND in Africa are sparse, although common observations in this region - and in other populations with relatively low life expectancy - include apparent earlier disease onset and lower disease incidence compared with the rest of the world. In\u00a0view of the HIV epidemic in Africa, we critically examine the evidence for an association between ALS and HIV infection. We briefly discuss conditions that might be regarded as ALS mimics and summarize the limited data on MND genetics in this region. Other issues pertinent to people living with MND in Africa include the absence of cognitive and behavioural data and the limited access to multidisciplinary clinics, therapies and palliative care. We share our perspective on how the ALS Africa Network is coordinating a shift in the African MND landscape to improve patient care.",

Despite decades of intensive research, effective disease-modifying therapies remain limited, underscoring the urgent need for innovative therapeutic strategies. This review highlights recent advances in the understanding of disease etiology and emerging treatment approaches, with a particular focus on modalities with translational potential. We discussed novel disease-modifying interventions, including gene and cell therapies, RNA-targeting strategies, and immunotherapies aimed at clearing misfolded proteins such as amyloid-\u03b2, tau, and \u03b1-synuclein. In parallel, we examined the evolving recognition of neuroinflammation and mitochondrial dysfunction as actionable therapeutic targets, alongside progress in precision medicine and biomarker-guided approaches that enable early diagnosis and individualized treatment. Additionally, we summarized developments in repurposed pharmacological agents, neuroprotective compounds, and lifestyle interventions, emphasizing the importance of integrative, multimodal strategies. Across AD, PD, and ALS, convergent molecular mechanisms, including protein misfolding, oxidative stress, and disrupted proteostasis, present opportunities for cross-disease therapeutic targeting. Finally, we addressed key challenges and future directions, including translating preclinical efficacy into clinical success, optimizing CNS-targeted delivery systems, and navigating ethical considerations surrounding gene editing and stem cell therapies.",

This commentary points to the implications of these findings that extend well beyond the time savings headline. The study reports substantial reduction in self-reported documentation time and increased satisfaction with the documentation system, yet workplace satisfaction and the perception that AI scribes are \"a good idea to implement\" did not improve. Taken together, these findings show three undertheorized issues for AI scribe implementation in nursing and long-term care. First, postimplementation increases in time spent reviewing entries and retrieving information indicate that AI scribes redistribute cognitive effort from authoring to verification, with unknown consequences for satisfaction, mastery, and error detection. Second, the apparent paradox of rising documentation satisfaction alongside falling expectations of AI quality represents user calibration. Third, the substantial equity considerations of automatic speech recognition documentation reflect a broader trend of AI scribe studies that treat equity as a caveat, rather than treating equitable performance as empirically measurable and testable across variations in linguistic styles, dialects, and social linguistic dimensions. To advance the field, the next generation of nursing AI scribe research must treat documentation as a heterogeneous bundle of authoring, reviewing, retrieving, and verifying activities with distinct satisfaction and error profiles; specify and validate end-user-defined anchor utilities, rather than having a narrow focus on diffuse improvement; and treat equity testing and reporting of both automatic speech recognition systems and workforce adoption as standard reporting expectations, rather than caveats.",

Despite extensive research, reliable prognostic biomarkers remain limited, with neurofilament light chain (NfL) being the only marker increasingly implemented in clinical practice. The objective of this study is to assess and compare the prognostic value of NfL, circulating markers of central nervous system (CNS) barrier dysfunction, inflammatory mediators, kynurenine pathway metabolites, and global metabolomic profiles in patients with ALS. Seventy-two patients with ALS from the prospective multicenter METABALS cohort were included. Serum, cerebrospinal fluid (CSF), and urine samples were collected at diagnosis. NfL concentrations, markers of blood-brain and blood-spinal cord barrier permeability (albumin quotient, S100B, neuron-specific enolase [NSE]), 48 inflammatory mediators, kynurenine pathway metabolites, and untargeted metabolomic profiles were measured. Associations with clinical features, disease progression, and survival were investigated using univariate analyses and multivariate models. Serum and CSF NfL concentrations were strongly associated with ALS Functional Rating Scale-Revised scores, respiratory function, diagnostic delay, and survival. Higher serum NfL concentrations at diagnosis predicted shorter survival (ROC AUC\u2009=\u20090.86). In all multivariate and multi-block models, serum NfL was the only biomarker independently associated with survival. Markers of CNS barrier integrity, inflammatory mediators, and metabolomic signatures showed limited prognostic value but provided insights into metabolic remodeling and barrier dysfunction. In this integrated multi-omics study, serum NfL clearly outperformed inflammatory, metabolic, and CNS barrier markers as a prognostic biomarker in ALS, supporting its central role in clinical stratification while complementary biological markers highlighted several relevant pathophysiological mechanisms.",

Early detection is critical for timely intervention; yet, conventional diagnostic methods remain costly and invasive. Speech-based assessment has emerged as a noninvasive alternative, as AD characteristically impairs linguistic abilities including fluency, coherence, and informational content. Recent advances in large language models (LLMs) offer new opportunities to extract structured linguistic features from transcribed speech for automated AD classification. However, existing LLM-based approaches often lack transparency and clinical interpretability, limiting their adoption in clinical workflows. This study aims to investigate the influence of linguistic features extracted from transcribed speech, as analyzed by LLMs, on the accuracy and interpretability of AD prediction. We propose a framework that leverages LLMs to analyze linguistic features extracted from transcribed speech for AD classification. Our approach focuses on 4 key aspects, including readability, fluency, richness of detail, and keyword relevance. To enhance classification accuracy, the framework integrates transcript embeddings with feature explanation embeddings, forming a comprehensive linguistic representation. We conducted extensive ablation studies to evaluate the contributions of individual features and benchmarked our framework against existing LLM-driven methodologies through pairwise explainability evaluations. Output stability was assessed across 3 independent pipeline runs. A fully local configuration (Llama 3 8B + nomic-embed-text) was tested to evaluate privacy-preserving deployment feasibility. Explainability was assessed via LLM-based pairwise comparison (Gemini-3.1-flash-lite) against the method of Bang et al across 54 correctly classified cases and by blinded evaluation from 2 neurologists. The proposed framework achieved a mean precision of 91.52%, a sensitivity of 91.08%, a specificity of 96.29%, and F1-score of 91.05% across 3 independent runs on the ADReSSo 2021 dataset, outperforming existing LLM-based approaches. A fully-local configuration (Llama 3 8B+nomic-embed-text, requiring no cloud application programming interface access) achieved an F1-score of 81.58%, demonstrating framework transferability to privacy-preserving deployment environments. Keyword relevance was the most influential feature (F1-score drop of 13.22 pp when removed). Explainability evaluations showed our method was preferred in 49 out of 54 cases via Gemini-3.1-flash-lite, with human experts preferring our method in 89 of 108 blinded assessments. These findings highlight that a structured linguistic feature analysis using LLMs provides a robust and interpretable framework for preliminary AD detection. Our approach offers a scalable and accessible solution that bridges artificial intelligence-driven text analysis with clinical applications, supporting early detection of cognitive decline through noninvasive assessment methods.",

This study aims to explore the utility of peripheral immune cells and glycosylation indices as potential diagnostic biomarkers for ALS to enhance the accuracy and efficiency of early ALS diagnosis. This retrospective study included 54 ALS patients diagnosed in our hospital from June 2023 to October 2024, along with 54 healthy controls. Blood samples and laboratory data, including levels of peripheral immune cells and glycosylation indices, were collected from both groups. Through logistic regression, random forest models, receiver operating characteristic (ROC) curve analysis, and SHAP interpretability analysis, the predictive abilities and clinical significance of each candidate indicator were screened and evaluated. Notable disparities were detected in age, leukocyte count, monocyte levels, glycated haemoglobin A1c (HbA1c), and haemoglobin glycation index (HGI) between the control and ALS groups (all P < 0.05). Logistic regression analysis revealed that age (OR = 1.114) and monocyte (OR = 3.174) were risk factors for ALS, while leukocyte (OR = 0.533) and HbA1c (OR = 0.069) were protective factors. The random forest algorithm, ranked by decreasing importance, showed that leukocyte, HGI, monocyte, and HbA1c level all influenced ALS. Using these indicators to predict ALS resulted in a false-positive rate of 18% and a false-negative rate of 6%. ROC curve analysis indicated that the combined use of leukocyte, monocyte, HbA1c level, and HGI provided the highest diagnostic value for ALS (AUC = 0.774), which was higher than that of any individual indicator (all P < 0.05). SHAP analysis visualization demonstrated that increased monocyte and decreased leukocyte, HGI, and HbA1c level were all associated with an increased risk of ALS onset, ranked in descending order of feature importance as monocyte, leukocyte, HGI, and HbA1c. Peripheral blood white blood cells, monocytes, HbA1c, and HGI can serve as potential diagnostic biomarkers for ALS. Combined detection can improve the diagnostic accuracy of ALS, facilitating early diagnosis and intervention, and ultimately improving patient prognosis. Further validation in cohorts including disease controls is required to confirm specificity.",

Original validation is based on a standard VF testing protocol including thin liquid, puree, and solid consistencies. Given that thickened liquid bolus trials are common in VF clinical testing protocols, we sought to determine the agreement in DIGESTV2 grades with and without the inclusion of moderately thick liquid bolus trials on DIGESTV2 outcomes in people with amyotrophic lateral sclerosis (pALS). This study represents a secondary analysis of VF examinations from a prospective longitudinal study conducted in 109 pALS. VF evaluations contained 10 barium trials spanning three International Dysphagia Diet Standardisation Initiative (IDDSI) levels (0-7). Duplicate, independent, and blinded ratings were completed. DIGESTV2 Efficiency and Safety grading was then completed under two conditions-with and without the inclusion of moderately thick liquid bolus trials into DIGESTV2 grading-to produce two sets of DIGESTV2 ratings for each VF study. Descriptives, percent agreement, and a weighted Cohen's kappa were performed on DIGESTV2 grades. A total of 373 VF examinations were included in this analysis. DIGESTV2 grade percent agreement with and without IDDSI Level 3 was excellent for Safety (98.1%), Efficiency (93.8%), and Total (94.1%) grades. Kappa values for Safety, Efficiency, and Total grades were .96, .89, and .91, respectively, indicating excellent agreement across bolus trial inclusion methods. Standard inclusion of moderately thick liquid bolus trials did not significantly impact DIGESTV2 grading in this data set.

Descriptive statistics, correlation analyses, and survival analyses were performed. Our cohort had 240 pwALS, 63% male, median age at onset 59.3 (IQR 16.5) years. Median time from onset to PSG was 27.5 (IQR 25) months. Most pwALS had spinal onset (79%). Spirometry at time of PSG showed a reduced Forced Vital Capacity (FVC) (58; (IQR 26) %). We saw a significant FVC decline (3.9; (IQR 4) % per month) in the months before PSG. The sleep quality assessment in pwALS revealed a reduced total sleep time (339; (IQR 144.7) minutes), diminished sleep efficiency (62.8; (IQR 26.5)%) and increased wake after sleep onset (172; (IQR 130.2) minutes) when compared to normal values of healthy age-matched adults.

A minimum disease duration of 2 years is required for the diagnosis of PLS, after which patients are classified as probable PLS (P-PLS) and subsequently as definite PLS (D-PLS) after 4 years. Our aim is to apply the current diagnostic criteria to a population-based cohort and investigate which clinical characteristics are associated with a diagnostic revision to ALS. This cohort study included patients meeting the current diagnostic criteria for PLS retrospectively from the Dutch Motor Neuron Disease Registry. Diagnostic revision to ALS was based on clinical assessment, EMG findings according to the revised El Escorial Criteria, or if patients had died from disease progression within 4 years of disease onset. Clinical characteristics were compared for patients who underwent diagnostic revision with ALS vs true PLS. Subdistribution hazard ratios (SHRs) for characteristics associated with diagnostic revision were determined using Fine-Gray regression. We included 478 patients (median age of onset 59.3 years, interquartile range 50.8-67.0, 47.9% female), of whom 311 (65.1%) met criteria for P-PLS and 167 (34.9%) for D-PLS at diagnosis. Eighty-eight patients (18%) underwent diagnostic revision to ALS, 76 cases (86%) before 4 years of disease duration. Patients whose diagnosis was revised to ALS had higher median age at onset (63.4 vs 58.0 years, p = 5.20 \u00d7 10-4), more often had bulbar onset (38.6% vs 19.7%, p = 6.19 \u00d7 10-4), and faster progression (median ALS Functional Rating Scale-revised slope 0.43 vs 0.18, p = 6.05 \u00d7 10-11). The risk of diagnostic revision increased if progression rate was faster (SHR 3.08 95% CI 1.69-5.60, p = 2.35 \u00d7 10-4) and if diagnosis was P-PLS compared with D-PLS (SHR 3.08, 95% CI 1.65-5.74, p = 3.96 \u00d7 10-4). In our cohort, most diagnostic revisions from PLS to ALS were in patients with a disease duration of less than 4 years. Besides disease duration, a faster progression rate was associated with diagnostic revision from PLS to ALS. Adding progression rate to the current diagnostic criteria could increase accuracy and help identify patients at higher risk of developing ALS.",

In humans, exposure to musical rhythm induces beat and meter perception, which has been shown to enhance attentional allocation and temporal prediction. Theories hypothesize that the predictive gains intrinsic to music rhythmicity may exert cascading effects on syntactic processing by modulating sensitivity to speech prosody. From this perspective, learning should also be boosted insofar as prosody tends to align with grammatical structure. In the present study, we introduce a novel behavioural paradigm to investigate the link between rhythmicity and grammar learning by testing whether the rhythmic beat facilitates the detection of grammar-like structures in artificial languages (ALs), implemented as non-adjacent dependencies (NADs) between variable syllables forming a speech stream (e.g., PU reliably predicts KI in PUlaruKI). A total of 147 participants were exposed to four ALs that varied in rhythmic, grammatical structure, and the alignment between the two: (i) a beat-inducing rhythm with no NADs; (ii) a beat-hindering rhythm with NADs; (iii) a beat-inducing rhythm with embedded NADs temporally misaligned, and (iv) NADs aligned with beat time-points. Results of the implicit and, after exposure, explicit learning measures demonstrate enhanced learning when NADs are embedded within beat-inducing rhythmic structures. Together, these findings suggest that rhythm enhances predictive and attentional mechanisms implicated in grammar learning, underscoring their role in its acquisition.",

We report a 78-year-old right-handed Asian woman with hypertension, diabetes, hepatic cirrhosis, and coronary artery disease who developed insidious word-finding difficulty progressing to severe anomia, impaired sentence repetition, and multidomain cognitive decline. Serial Indonesian MMSE, MoCA-Ina, Consortium to Establish a Registry for Alzheimer's Disease (CERAD), and Tes Afasia untuk Diagnosis, Informasi, dan Rehabilitasi (TADIR) assessments showed early amnestic and executive deficits followed by dominant phonological and naming impairment, while MRI revealed left-predominant temporo-parietal and medial temporal atrophy with small-vessel white matter disease, consistent with mixed Alzheimer and vascular pathology. She received donepezil, low-dose clobazam, and targeted speech-language and cognitive rehabilitation with partial symptomatic benefit. This case highlights the importance of detailed language assessment and culturally adapted neuropsychological batteries to identify lvPPA within mixed dementia in resource-limited settings.",

The absence of specific diagnostic biomarkers leads to diagnostic delays, hindering early intervention and management. This review provides a critical appraisal of fluid-based biomarkers for ALS across multiple sources-cerebrospinal fluid (CSF), blood, urine, saliva, and tears-with emphasis on their diagnostic and prognostic potential, limitations, and readiness for clinical translation. While neurofilaments (NfL, pNfH) are well-established as sensitive indicators of neuroaxonal injury and are increasingly used as prognostic and pharmacodynamic markers in clinical trials, they lack disease specificity. Biomarkers reflecting ALS-specific pathology, such as TDP-43 species and C9orf72 dipeptide repeat proteins (DPRs), show promise but remain in early validation stages with limited multicenter data. Emerging markers from non-invasive sources (urine p75ECD, salivary chromogranin A, tear metabolomics) offer potential for repeated sampling but require rigorous external validation before clinical adoption. To address current gaps, we introduce a standardized evidence grading framework (Tier 1-3) and a comprehensive reporting template for biomarker studies, including explicit performance metrics (AUC, sensitivity, specificity, confidence intervals) and validation status. We also propose minimum reporting standards for study design, pre-analytical variables, and statistical rigor, modeled on REMARK guidelines. A roadmap for biomarker validation and a cross-fluid comparison matrix are provided to guide future research. Despite considerable progress, significant challenges remain, including biological heterogeneity, pre-analytical variability, and insufficient external validation. Future efforts should prioritize multicenter prospective studies, assay harmonization, ethical frameworks for early diagnosis, and integration of emerging technologies such as artificial intelligence and digital twins. Fluid-based biomarkers, while not yet replacing clinical evaluation, are essential tools for accelerating drug development, enabling patient stratification, and moving toward personalized medicine in ALS.",

Due to the strong link between dysphagia, weight loss, and disease progression, this study investigates the relationship between body composition and clinical outcomes in ALS adults. This cross-sectional study involved 93 ALS adults (29 females, 64 males) from Imam Khomeini Hospital in Tehran, selected based on EI Escorial criteria. Researchers assessed body composition, functional abilities, and disease progression using ALSFRS-R, MRC scores, and DPR, analyzing associations through linear regression models with RStudio in conjunction with R software. In this study, significant differences were found between the third and first tertiles for various measures. Significant associations were observed between body composition and ALSFRS-R for MAC (\u03b2: 3.0; P\u2009=\u20090.006), with underweight and moderately active adults exhibiting notable differences. The MRC score was positively associated with FFM (\u03b2: 5.8; P\u2009=\u20090.002), SLM (\u03b2: 5.6; P\u2009=\u20090.002), SMM (\u03b2: 3.8; P\u2009=\u20090.001), MAC (\u03b2: 3.2; P\u2009=\u20090.002), ICW (\u03b2: 2.7; P\u2009=\u20090.002), and ECW (\u03b2: 1.5; P\u2009=\u20090.003), while underweight and low-to-moderate physical activity adults indicated inverse associations. For DPR, significant relationships were noted for weight (\u03b2: 4.5; 95% CI: 0.02, 9.3; P\u2009=\u20090.002) and FFM (\u03b2: 11; P\u2009<\u20090.001), influenced by gender and physical activity. The findings highlight the role of gender, weight, and activity in ALS management, suggesting that maintaining a healthy weight along and muscle mass along with regular activity is associated with better outcomes.

However, detection can be confounded due to factors like fatigue and testing anxiety. Cumulus neuroscience developed NeuLogiq(R), a multi-modal neurocognitive platform that can be used in clinic or at home, providing an ecologically valid measure of cognition. This study examined the feasibility and usability of NeuLogiq in plwALS, plwFTD, and controls, and compared performance on gold standard neuropsychological assessments with corresponding NeuLogiq digital assessments. Over 8 months, plwALS (n\u2009=\u200911), plwFTD (n\u2009=\u20097), and matched healthy controls (n\u2009=\u200910) completed longitudinal full neuropsychological assessment, as well as three 25-minute NeuLogiq Platform sessions every 2 weeks in their homes. Participants adhered well to the study schedule, conducting over 32/54 sessions on average. All groups rated usability in the 'good' or 'excellent' range and had\u2009>\u200980% complete data. Baseline group differences were detectable on both NeuLogiq digital assessments and benchmark neuropsychological assessments of similar cognitive domains. Longitudinal mixed effects models found that the ALS group showed decline on NeuLogiq measures of emotion recognition and speech fluency. These findings suggest that the NeuLogiq platform is feasible and usable for plwALS and plwFTD, and can identify cognitive deficits to a similar extent as benchmark assessments over time.",

Remarkable global investment has been dedicated to enteric infectious disease prevention and control; however, the shifting global health landscape is testing the continuance of progress. To evaluate the current status and guide future interventions, we present the latest epidemiological estimates of enteric infectious diseases from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023 and assess progress towards the Global Action Plan for the Prevention and Control of Pneumonia and Diarrhoea (GAPPD) mortality target of fewer than 20 deaths per 100\u2008000 children younger than 5 years by 2025. We quantified the incidence, mortality, and disability-adjusted life-years (DALYs) of enteric infectious diseases by age, sex, and year across 204 countries and territories from 1990 to 2023. In GBD 2023, the following were considered under the category of enteric infectious diseases: diarrhoeal diseases, enteric fever (typhoid and paratyphoid), invasive non-typhoidal Salmonella spp (iNTS) infections, and other intestinal infectious diseases. We also examined 15 aetiologies contributing to diarrhoeal diseases. Incidence and prevalence were estimated with DisMod-MR (version 2.1), a Bayesian meta-regression tool, drawing on data from systematic reviews, population-based surveys, claims data, and hospital sources. Cause-specific mortality was modelled with Cause of Death Ensemble Modelling based on data from sources including vital registration, mortality surveillance, verbal autopsy, and minimally invasive tissue sampling. Years of life lost and years lived with disability were computed and combined to derive DALYs. For aetiology-specific estimation, population-attributable fractions (PAFs) for 15 pathogens were derived with a counterfactual framework. Point estimates and 95% uncertainty intervals (UIs) were generated from 250 draws from the posterior distribution. In 2023, enteric infectious diseases resulted in an estimated 1\u00b727 million (95% UI 0\u00b7963-1\u00b768) deaths globally, declining from 3\u00b769 million (3\u00b704-4\u00b756) in 1990. The global age-standardised mortality rate (ASMR) decreased from 74\u00b71 (62\u00b70-92\u00b79) per 100\u2008000 population to 16\u00b74 (12\u00b76-21\u00b73) per 100\u2008000 population during the same period. Diarrhoeal diseases accounted for most deaths in 2023 (1\u00b711 million [0\u00b7811-1\u00b754]), followed by enteric fever and iNTS. South Asia and sub-Saharan Africa remained the most affected regions in 2023, with 599\u2008000 (441\u2008000-882\u2008000) and 501\u2008000 (373\u2008000-648\u2008000) deaths due to enteric infectious diseases, respectively, predominantly from diarrhoeal disease. Rotavirus was the leading cause of all-age diarrhoeal disease deaths (PAF 16\u00b73% [12\u00b70-21\u00b75]), followed by norovirus (10\u00b72% [2\u00b74-17\u00b70]) and Shigella spp (9\u00b73% [5\u00b74-15\u00b72]). Among children younger than 5 years, PAFs of deaths due to diarrhoeal diseases were 40\u00b72% (32\u00b75-48\u00b75) for rotavirus, 24\u00b70% (15\u00b71-36\u00b77) for Shigella spp, and 23\u00b74% (13\u00b77-34\u00b73) for adenovirus. Across 204 countries and territories, 141 met the GAPPD mortality target in 2023. The driving aetiologies among countries that did not meet the target in 2023 varied slightly by GBD super-region, but the highest or second-highest number of deaths in children younger than 5 years were consistently attributed to rotavirus. Astrovirus and sapovirus, newly included in GBD 2023, were responsible for 24\u2008600 (6290-49\u2008000) and 18\u2008800 (4650-44\u2008400) deaths, respectively, in 2023, mainly in children younger than 5 years. Our findings show that mortality and ASMRs of enteric infectious diseases declined substantially between 1990 and 2023. This decline is consistent with the expansion of public health measures and broader socioeconomic development. However, the burden in 2023 remains considerably high, with the highest mortality concentrated in sub-Saharan Africa and south Asia. Considering that more than a quarter of all countries had yet to meet the GAPPD mortality target in 2023, sustained efforts are needed to address the persistent burden in affected countries and to adapt to the changing global health landscape.

A corpus of atypical speech for spoken language understanding and automatic speech recognition.\nAbstract: Speech technologies, such as automatic speech recognition or spoken language understanding, are not usually adapted to atypical speech, i.e., the speech of people with dysarthria, dysphonia, or another type of speech impairment. That prevents atypical speakers from leveraging speech assistants or other human-machine-interaction-powered platforms, which could make their lives easier or increase their independence. In this article, we present HeyJay!, a new corpus of atypical speech in English language from participants with neurodegenerative disorders, including Parkinson's Disease, or Amyotrophic Lateral Sclerosis. The current corpus version comprises 8,669 utterance recordings, including supervised transcriptions and intent annotations. In this study, we demonstrate the validity of the corpus by applying it to automatic speech recognition, spoken language understanding, and data augmentation tasks. Additionally, the dataset includes speech quality ratings for each participant, performed by expert speech and language pathologists. This corpus, the first one with intent annotation of atypical speech that is publicly available, is intended to create more fair speech technologies for atypical speakers by adapting and improving the state of the art, and to facilitate further research in the field.",

Little is known about the terminal phase experiences, symptom prevalence, and end-of-life care patterns of people with ALS (PALS) in India. This study aimed to assess terminal events and caregiver-reported outcomes in PALS to identify gaps in ALS care delivery in India. A cross-sectional telephonic survey was conducted among bereaved caregivers of PALS enrolled in the Neuropalliative and Supportive Care project between December 2021 and May 2024. A structured, validated questionnaire was used to collect data on demographics, terminal-phase symptoms, medical interventions, and the nature of death as perceived by primary caregivers. Descriptive statistics and appropriate statistical analyses were performed. A total of 130 caregivers participated in the survey; the majority (57.7%) were sons or daughters. Among the 130 PALS, 76 (58.5%) were men; 56.2% had limb onset and 43.8% had bulbar onset. The mean age at death was 53.5 \u00b1 11.4 years. Most patients (57.7%) died at home, and 29.2% experienced sudden death. Patients who died in the hospital were more likely to be on invasive mechanical ventilation ( P < 0.001). The most common terminal symptoms were breathlessness (79.2%), excessive oral secretions (54.6%), followed by anxiety or restlessness (44.6%). Only 20% received bilevel positive airway pressure, and 25.4% were on percutaneous endoscopic gastrostomy. A significant association was found between bulbar onset and assisted feeding ( P = 0.002). This study highlights the need for proactive, community-integrated palliative care services and emphasizes the urgency of early intervention and caregiver support to improve end-of-life experiences in PALS in India.",

An operator-independent AI-based automatic segmentation of the tongue was applied to 3-D MRI data of the head in SBMA in order to quantify the tongue atrophy. Thirty-nine patients with SBMA and 51 age-matched healthy controls underwent MRI which were used for tongue volume quantification. A single triplanar convolutional neural network of U-Net architecture trained on axial, coronal, and sagittal planes was used for the segmentation of the tongue in MRI scans of the head, the resulting volumes were processed slice-wise across the three orientations and corrected for age. At the group level, a significant atrophy of the tongue was observed in SBMA when compared to controls (p\u2009<\u20090.05). Atrophy correlated well with total SBMA-functional rating scale and even more with bulbar subscores. In summary, the study employed an AI-assisted advanced imaging analysis to quantify the tongue morphology in individuals with SBMA in correlation to clinical bulbar function, suggesting this approach as a potential biomarker for disease assessment.",

The primary aim of this translational pilot study was to identify a disease-specific, TDP-43-related, gene-microRNA (miRNA) signature in peripheral blood mononuclear cells (PBMCs) of ALS patients with potential diagnostic value. To this end, we first identified differentially expressed disease-specific genes (dsDEGs) using a TDP-43-based rat model of ALS, generated by stereotaxic infusion of full-length (FL) TAR DNA-binding protein 43 (TDP-43) into the motor cortex. Transcriptomic profiling of the motor cortex revealed candidate dsDEGs, which were subsequently validated by RT-qPCR in motor cortex, spinal cord, and PBMCs from the same animals. To assess translational relevance, expression levels of these dsDEGs were analyzed in PBMCs from early- to mid-stage ALS patients and matched healthy controls, while disease specificity was evaluated using Parkinson's disease (PD) samples. In parallel, conserved miRNAs predicted to target the identified dsDEGs were examined in both rat and human PBMCs. Five dsDEGs, Mctp1, Penk, Mt2A, Drd1, and Rasgrp2, were consistently dysregulated across central and peripheral tissues in the TDP-43 rat model. RT-qPCR analysis of human PBMCs confirmed significant and selective dysregulation of these genes in ALS, but not in PD, supporting disease specificity. Moreover, exposure of human neuroblastoma cells and healthy PBMCs to TDP-43 recapitulated the ALS-like expression changes. Computational and experimental analyses identified seven conserved miRNAs targeting these dsDEGs, of which four were significantly downregulated in ALS PBMCs, supporting a coordinated regulatory network. Receiver operating characteristic (ROC) analyses demonstrated strong discriminative performance for both the gene signature (AUC 0.87-1.00) and the associated miRNAs (AUC 0.95-1.00). Together, these findings define a novel PBMC-based gene-miRNA signature that mirrors central ALS pathology and shows high diagnostic accuracy and disease specificity, highlighting its potential as a minimally invasive biomarker for ALS.",

The aim of this study was to evaluate ventilation parameters and healthcare resource utilization in a tele-monitoring program (TG) compared to usual care (UG). A retrospective comparative study was conducted, comparing HMV patients assigned to telematic follow-up with a historical cohort receiving standard in-person follow-up. Ventilation parameters included apnea-hypopnea index (AHI), average daily use (h/day), and mean leak (L/min). Efficiency was as-sessed by the total number of hospital visits and in-person hospital visits. Average daily use (8.3\u00b12.9 h/day vs. 8.5\u00b13.4 h/day; p=0.714) and mean leak (6.4\u00b111.9 L/min vs. 6.3\u00b19.6 L/min; p=0.701) did not differ significantly between groups. The TG showed a lower AHI compared with the UG [4.1\u00b15.0/hour vs. 7.9\u00b112.2/hour; respectively (p=0.008)]. The TG was also associated with fewer annual total visits (3.5\u00b12.4 vs. 6.9\u00b15.0; p<0.001) and fewer annual in-person visits (2.1\u00b11.6 vs. 6.9\u00b15.0; p<0.001). Kaplan-Meier curves were used for descriptive purposes. In multivariable Cox regression adjusted for age category, diagnostic group, baseline arterial blood carbon dioxide pressure, and sex, the TG was associated with a lower hazard of death (0.51; 95% confidence interval 0.24-1.09; p=0.08). These findings indicate that telemonitoring combined with synchronous video consultation was associated with better ventilatory control (lower AHI) and lower use of in-person healthcare visits, with-out evidence of impaired adherence or safety.",

We evaluated whether early respiratory decline around diagnosis provides prognostic information in a real-world landmark framework. This single-center retrospective cohort screened 94 consecutive patients diagnosed between April 2019 and December 2025. A 6-month landmark was used. Early decline was estimated from %FVC values between -\u200930 and +\u2009180 days around diagnosis. The primary model included age and early %FVC decline; robustness analyses included time-varying Cox, piecewise Cox, RMST, included-vs-excluded comparison, death-only analysis, and slope-quality filtering. Of 94 screened patients, 62 met baseline eligibility, 56 had calculable early slope, and 45 entered the landmark cohort; 28 post-landmark composite events occurred. In the Cox model, faster early %FVC decline was associated with higher hazard of death or invasive mechanical ventilation via tracheostomy (HR 1.33 per 1%/month faster decline, 95% CI 1.14-1.55, p\u2009<\u20090.001). PH diagnostics suggested non-proportionality (%FVC p\u2009=\u20090.031; NIV p\u2009=\u20090.034 in the expanded model), so this HR was interpreted as an average follow-up association and complemented by PH-robust analyses. The signal was stronger early than late, remained consistent in a death-only analysis, and favored the slower-decline group by RMST at 24 and 36 months. In this selected measurement-capable landmark cohort, early respiratory decline provided a clinically meaningful short-to-medium term prognostic signal for post-landmark adverse outcomes. External validation is required before broader generalization beyond measurement-capable landmark populations.",

This study investigated whether immunoglobulin G (IgG) and immunoglobulin M (IgM) anti-glycolipid antibodies are associated with clinical manifestations of ALS, particularly decline in respiratory function. This was a retrospective observational cohort study of the patients with ALS. Among patients with definite or probable limb-onset ALS, 11 patients in the glycolipid IgG-positive group were compared with 15 patients in the IgG-negative group, and 5 patients in the glycolipid IgM-positive group were compared with 9 patients in the IgM-negative group, with adjustment for age. Associations between anti-glycolipid antibody status and respiratory function were assessed using Kaplan-Meier survival analysis and Cox proportional hazards models. The time to decline of percent forced vital capacity (%FVC) below 80% and 60% was significantly shorter in the IgG-positive group than in the IgG-negative group (p\u00a0=\u00a00.002 and p\u00a0=\u00a00.025, respectively). Cox proportional hazards analysis demonstrated that IgG antibody positivity was an independent risk factor for earlier decline in %FVC to 80%. These findings suggest that anti-glycolipid IgG antibodies may be associated with respiratory function decline in ALS. Larger comprehensive studies will be required to validate these results and to elucidate the underlying pathophysiological mechanisms.",
        "42261056": "ID: 42261056\nTitle: The Flail Limb Syndrome.\nAbstract: The flail limb syndrome is primarily a lower motor neuron disorder that initially affects proximal arm muscles (flail arm syndrome-FAS) or distal leg muscles (flail leg syndrome-FLS). Both were recognized early on (1886 for FAS and 1918 for FLS) as somewhat distinct from classic amyotrophic lateral sclerosis (ALS). Descriptions in the literature are case series with limited information on electrophysiologic features (central and peripheral), cognitive involvement, and genetic mutations. What follows is a compilation of these features. The flail limb syndromes are rare, representing ~7%-8% of ALS. They have a higher ratio of males to females compared to classic ALS. Both are defined by predominant focal arm or leg weakness for ~2\u2009years before progression to other regions, although there can be early and mild clinical or electrophysiologic evidence for denervation and reinnervation in other regions during the initial period. Ultimately, there is progression to respiratory failure, but at a slower rate compared to classic ALS. Upper motor neuron clinical signs are variable, but transcortical magnetic stimulation paradigms and magnetic resonance imaging tractography support upper motor neuron loss. Tests of the split hand pattern show it is rare compared to ALS. Dementia is also rare. Genetic testing supports a spectrum of ALS-related gene mutations but at a lower frequency than with classic ALS, and no gene mutation is predominant. Diagnosis requires ~2\u2009years of regional stability to predict the better prognosis for the flail limb syndromes.",

This retrospective cross-sectional study evaluated the frequency of sensory and entrapment neuropathies in 114 patients with ALS using electrodiagnostic (EDX) studies. Demographic characteristics, comorbidities, and sensory and autonomic symptoms were documented. Electrophysiological evidence of sensory neuropathy was identified in 20 patients overall (20/114, 17.5%), including 10 patients without diabetes mellitus (DM), whereas entrapment neuropathy was detected in 28 patients overall (28/114, 24.6%), including 16 of those without DM or hypothyroidism. Sensory neuropathy was significantly associated with both DM and a history of chronic disease. In contrast, these comorbid conditions were not significantly associated with entrapment neuropathy. Furthermore, patient-reported symptoms showed no correlation with electrophysiological evidence of sensory involvement on EDX. Sensory neuropathy was more frequent in patients with spinal-onset than bulbar-onset disease, although the difference was not statistically significant. This study confirms that sensory involvement is not uncommon in ALS. Although clinical symptoms are poor predictors, electrophysiological abnormalities consistent with sensory and entrapment neuropathies are common. A significant proportion of these abnormalities are idiopathic and may directly reflect the disease process itself, particularly in spinal-onset cases.",

In this study, we reconstruct the developmental trajectory of cultured cortical networks derived from SOD1G93A mouse embryos using a multimodal approach, by combining morphometric, electrophysiological, pharmacological, molecular, computational, and machine-learning techniques. We prove that ALS neurons fail to acquire mature polarization and connectivity, displaying a transient phase of hyperexcitability that precedes a progressive collapse of network organization. Astrocytic dysfunction emerges early and impairs synchronization, establishing a causal link between glial dysfunction and neuronal instability. The analysis of synaptic transmission reveals an excitatory bias followed by maladaptive inhibitory recruitment and GABA/glutamate co-release, causing fragmented and inefficient network topologies. Finally, in silico modelling identified deficient intrinsic adaptation as a key driver of hyperexcitability. Together, our findings position ALS as a developmentally rooted disorder of cultured cortical network homeostasis, driven by glial, synaptic, and intrinsic adaptation failures. By demonstrating that cortical dysfunction is embedded before degeneration, this work provides a unifying framework connecting early network instability to disease progression and establishes electrophysiological network signatures, detected by machine learning classifiers, as candidate biomarkers for early diagnosis and therapeutic screening.",

All coding exons and flanking intronic regions of FUS were analyzed by Sanger sequencing in 650 unrelated Taiwanese patients with ALS. Clinical characteristics of patients carrying FUS variants were evaluated. Haplotype analysis using polymorphic microsatellite markers flanking FUS was performed to assess a potential founder effect of the p.H517D variant. Eight distinct heterozygous pathogenic FUS variants were identified in 11 probands and five affected relatives, including six missense and two frameshift variants. The most frequent variant was p.H517D, detected in four probands. A novel frameshift variant, p.G499Vfs*30, was identified as a de novo mutation in a juvenile-onset ALS patient. Compared with the non FUS-associated ALS cohort, patients with FUS-associated ALS had a significantly younger mean age at onset (40.1 vs 56.6\u00a0years) and more frequent bulbar onset (50% vs 19%). Haplotype analysis suggested a common founder for the p.H517D variant. FUS mutations accounted for 1.7% of ALS cases in this Taiwanese cohort. The recurrent p.H517D variant appears to represent a population-specific founder mutation. Patients with FUS variants presented with earlier disease onset and heterogeneous clinical phenotypes, and de novo variants contributed to juvenile-onset disease.",

This study evaluated a Praat-based script that estimates global speech timing by detecting syllable nuclei via amplitude dips. Speaking rate (syllables/total duration) and articulation rate (syllables/speaking time) were measured manually and with an automated script across speakers with multiple sclerosis (MS), Parkinson's disease (PD), and healthy controls. Sixty participants (20 per group) completed sentence, paragraph, and monologue tasks (N\u2009=\u2009180 recordings). Default script parameters were compared to an optimized version with manually tuned dip thresholds. Analyses included error metrics, linear mixed-effects models, and generalizability analysis. Automated speaking rate measures showed strong correlations with manual measures across all groups and tasks (r\u2009=\u20090.623-0.998). However, default automated estimates underestimated both speaking and articulation rates, especially in clinical speakers and for the monologue task. Articulation rate was more sensitive to the measurement method, which accounted for nearly half of the total variance. Optimization of the Praat script parameters reduced proportional error by \u223c60%, with varying effects across groups. Findings suggest that optimized automated methods can improve measurement accuracy, but population- and task-specific challenges persist, especially for articulation rate in MS and PD speakers.",

We evaluated the feasibility, reliability, and validity of unsupervised smartphone-based cognitive tests in a registry-based cohort. Adults without a record of cognitive impairment (N\u00a0=\u00a01815; ages 18-92) were recruited from the University of California, San Francisco (UCSF) Brain Health Registry to complete three unsupervised smartphone cognitive testing sessions within 2 weeks. Reliability was assessed with correlations between sessions. Linear regression models tested associations of smartphone tasks with demographics, self- and informant-rated cognitive concerns, and web-based cognitive testing (Cogstate Brief Battery).

This study proposes a multiview spectrogram-based deep learning framework integrating recognition-aware context for Parkinson disease detection from voice recordings. Voice recordings from 203 participants (121 with Parkinson disease and 82 healthy controls) were collected prospectively. Three spectrogram representations (Mel, short-time Fourier transform, and constant-Q transform) were extracted and processed through parallel convolutional neural network branches. A recognition ratio (RR) feature vector derived from automatic speech recognition transcript agreement was optionally fused with spectrogram embeddings. Models were evaluated using strict subject-wise 5-fold cross-validation. Multiview spectrogram recognition-aware Parkinson detection network achieved a mean test accuracy of 86.9% (SD 25.2%) using 3-view spectrogram fusion, improving to 97.4% (SD 5.7%) when incorporating the RR feature. RR integration reduced the false negative rate by approximately 84.5%, substantially improving sensitivity in screening-oriented settings. Combining multiview spectrogram learning with recognition-aware context significantly enhances voice-based Parkinson disease classification under leakage-free evaluation. These findings support the potential of this approach for noninvasive screening in structured recording settings, while further validation in diverse real-world environments is needed.",

MicroRNAs (miRNAs) have emerged as promising biomarkers due to their involvement in tu- mor progression and in regulating therapy sensitivity. however, the combined clinical signifi ance of circulating and tumor-associated miRNAs, such as hsa-miR-26b-5p and hsa-miR-186-5p, remains insuffi\u00a0\u00a0 \u00a0tly elucidated. Materi- als and Methods. Expression levels of hsa-miR-26b-5p and hsa-miR-186-5p were analyzed in serum and tumor tis- sue of 124 BC patients. Associations with clinicopathological parameters were assessed. The prognostic signifi ance was evaluated based on disease progression and recurrence within 3 years. The predictive value was determined in patients receiving neoadjuvant chemotherapy (4AC regimen) using response assessment and ROC analysis. Re- sults. young BC patients (\u226445 years) demonstrated signifi antly lower circulating levels of both miRNAs. Serum hsa-miR-186-5p expression was associated with early-stage disease, tumor size, lymph node status, and molecular subtype. Increased circulating hsa-miR-26b-5p levels were linked to disease progression, whereas decreased hsa- miR-186-5p levels were observed in patients with unfavorable outcomes. In tumor tissue, hsa-miR-26b-5p expres- sion correlated with tumor grade, size, and metastatic status, showing elevated levels in poorly differentiated tumors and reduced expression in metastatic disease. In contrast, hsa-miR-186-5p was associated with the molecular sub- type and lymph node involvement, with the highest expression observed in hER2-positive tumors and in patients with recurrence. Elevated levels of hsa-miR-186-5p in both serum and tumor tissue were associated with reduced sensitivity to doxorubicin-based neoadjuvant chemotherapy. ROC analysis confi med its predictive value (AUC = \u00a00.750 for serum and 0.818 for tumor tissue). No signifi ant association between hsa-miR-26b-5p and chemothe- rapy response was observed. hsa-miR-26b-5p and hsa-miR-186-5p demonstrate complementary roles in BC biology. hsa-miR-26b-5p is primarily associated with tumor aggressiveness and cancer progression, whereas hsa-miR-186-5p refl cts its molecular characteristics and response to chemotherapy.

        "42296263": "ID: 42296263\nTitle: Whole-body muscle MRI improves diagnostic certainty in amyotrophic lateral sclerosis.\nAbstract: Introduction: Early diagnosis of amyotrophic lateral sclerosis (ALS) remains challenging due to the absence of a definitive biomarker and the difficulty of demonstrating widespread lower motor neuron (LMN) involvement. Whole-body muscle MRI (WB-MRI) enables comprehensive assessment of muscle involvement and may improve detection of LMN dysfunction. This study aimed to evaluate whether WB-MRI improves diagnostic certainty in ALS when combined with clinical and electromyography (EMG) assessment. Methods: In this prospective single-center study, 47 patients with ALS underwent clinical examination, EMG, and WB-MRI. Diagnostic classification according to the Awaji criteria was assessed using clinical and EMG data alone and after integration of MRI markers of LMN involvement, including fatty infiltration and muscle edema, or muscle edema alone as a surrogate marker. Results: WB-MRI identified additional LMN-involved regions in 27.7% of patients when both fatty infiltration and muscle edema were considered, and in 42.6% when considering muscle edema alone. This resulted in diagnostic upgrading in 14.9% and 25.5% of patients, respectively. The proportion of definite ALS increased from 8.5% to 17.0% when muscle edema alone was considered. MRI had limited impact on diagnostic classification according to the Gold Coast criteria. Among patients without LMN involvement on clinical and EMG assessment (all with bulbar-onset), 50% were reclassified after MRI. Conclusion: WB-MRI improves detection of LMN involvement and increases diagnostic certainty according to the Awaji criteria, with muscle edema appearing to be the most relevant MRI marker for integration into ALS diagnostic assessment.",

Recent work has demonstrated highly accurate intracortical BCIs for speech and cursor control, but two critical capabilities needed for practical viability were unmet: independent at-home operation without researcher assistance and reliable long-term performance supporting accurate speech and cursor decoding. Here we demonstrate the independent and near-daily use of a multimodal BCI with novel brain-to-text speech and computer cursor decoders by a man with paralysis and severe dysarthria due to amyotrophic lateral sclerosis. Over nearly 2\u2009years, the participant used the BCI for more than 3,800\u2009h at home with no researchers present to maintain rich interpersonal communication with his family and friends, independently control his personal computer and sustain full-time employment-despite being paralyzed. He communicated 183,060 sentences-totaling 1,960,163 words-at an average rate of 56 words per minute. He labeled 92% of sentences as being decoded at least mostly correctly. In formal quantifications of performance where he was asked to say words presented on a screen, attempted speech was consistently decoded with more than 99% word accuracy (125,000 word vocabulary). The participant also used the speech BCI as keyboard input and the cursor BCI as mouse input to control his personal computer, enabling him to send text messages and emails and to browse the internet. These results demonstrate that intracortical BCIs have the potential to support independent use in the home, marking a critical step toward practical assistive technology for people with severe motor impairment.",

Here we tested whether plasma proteomics can be used to analyze cell type-specific aging. From analyses of over 7,000 plasma proteins measured in 60,542 individuals, we developed machine learning models to estimate the biological age of over 40 cell types spanning neuronal, immune, glial, endocrine, epithelial and musculoskeletal origins. We observed that 20-25% of individuals exhibited accelerated aging in a single cell type and 1-3% in 10 or more cell types. Cellular aging signatures were associated with disease status and predicted incident disease and mortality over 15 years of follow-up. Individuals with the APOE4 genotype showed older astrocytes but younger macrophages compared to APOE3 carriers, whereas the APOE2 genotype had inverse associations. Moreover, extreme astrocyte aging tripled the risk of incident Alzheimer's Disease in individuals with two APOE4 alleles, while youthful astrocytes reduced risk. Individuals with extremely aged compared to youthful skeletal myocytes exhibited a 12.7-fold higher risk of developing amyotrophic lateral sclerosis. In individuals who smoked, extreme respiratory epithelial cell aging was associated with a 58% higher lung cancer risk compared to smoking alone. Specific cellular vulnerabilities and cumulative cellular aging burden influenced survival, with youthful immune and neuronal cell types conferring protective effects. Finally, we developed a polycellular aging risk score that stratified mortality risk across cohorts and proteomics platforms. These findings establish a framework for quantifying human physiology at cellular resolution, revealing heterogeneous aging trajectories and their impact on disease susceptibility and resilience.",

Despite extensive research, riluzole and edaravone remain the only globally approved disease-modifying therapies, offering modest survival benefits. This review summarizes current understanding of ALS pathogenesis, approved pharmacological treatments, and emerging gene-, RNA-, and cell-based therapeutic strategies. Particular emphasis is placed on regulatory considerations and evolving clinical trial designs in ALS drug development. The accelerated approval and subsequent withdrawal of sodium phenylbutyrate-taurursodiol (AMX0035) are discussed as a critical case study highlighting the challenges of regulatory flexibility in rare, fatal diseases.

Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration. Comparing these age-related diseases will facilitate the identification of shared risk factors, convergent molecular pathways, and potential cross-applicable therapeutic strategies, such as anti-inflammatory, anti-complementary, anti-apoptotic, and anti-VEGF-based approaches. This knowledge may enhance understanding of neurodegenerative diseases, help identify early biomarker development for diagnosis, and enable the design of targeted therapeutic strategies.",

It is widely assumed that cortical structures beyond motor neurons are relatively preserved, and patients in the end-stage ALS are regarded as being in complete locked-in syndrome (cLIS). However, emerging evidence suggests substantial heterogeneity in cognitive functioning among ALS patients, indicating possible extra-motor cortical involvement and impaired levels of consciousness. We report a case study assessing electrophysiological markers and auditory system integrity to evaluate the presence of covert consciousness in end-stage ALS. The patient was a 42-year-old woman with bulbar-onset, end-stage ALS, a six-year disease duration, and no means of communication. She underwent several EEG-based protocols, including resting-state EEG (RS-EEG), a passive auditory oddball paradigm, and 40\u2009Hz auditory steady-state responses (ASSR). Audiological evaluation comprised transient-evoked and distortion-product otoacoustic emissions, as well as auditory brainstem responses (ABR). RS-EEG was dominated by prefrontal 1-3\u2009Hz activity resembling frontal intermittent rhythmic delta activity. Power spectra were poorly differentiated and consistent with a 1/f profile. No event-related potentials were observed in the oddball paradigm, and no ASSR responses were detected. Audiological testing revealed absent otoacoustic emissions and ABR indicating severe to profound hearing loss. Our findings indicate severe cortical dysfunction and provide no electrophysiological evidence of covert consciousness. The electrophysiological profile closely resembles that observed in unresponsive wakefulness syndrome. This case supports the hypothesis that advanced ALS following cLIS onset may be more appropriately conceptualized as a disorder of consciousness rather than persistent cLIS.",

Although deep brain stimulation addresses these symptoms, its use is limited by invasiveness, potential device failure, and the need for ongoing maintenance. Magnetic resonance-guided focused ultrasound (MRgFUS) provides incisionless, image-guided ablation as an alternative. However, the benefits and harms of staged, bilateral MRgFUS pallidothalamic tractotomy have not been evaluated systematically in prospective multicentre studies. In this prospective, multicentre, single-arm study, adults with idiopathic, levodopa-responsive Parkinson's disease and motor complications (Movement Disorders Society Unified Parkinson's Disease Rating Scale [MDS-UPDRS] part IV item 4.2 or 4.4 score \u22652) were enrolled at nine investigational centres (six in the USA, two in Spain, and one in Taiwan). Participants underwent unilateral MRgFUS pallidothalamic tractotomy to the symptom-dominant side. Contralateral pallidothalamic tractotomy followed a minimum of 6 months later for participants meeting prespecified criteria. The primary efficacy endpoint was percent change from baseline to 3 months after the second procedure in the summed MDS-UPDRS part III off-medication upper and lower extremity (ULE) motor scores. Safety outcomes were incidence, severity, and persistence of treatment-related adverse events in the 12 months after each procedure. Safety and efficacy of unilateral treatment were evaluated in the unilateral intention-to-treat (ITT) and safety populations, defined as all patients receiving one or more sonications during the first procedure. The primary outcome and safety of bilateral treatment were evaluated in the bilateral modified ITT (mITT) and safety populations, which required one or more sonications during the second procedure, a baseline motor assessment, and at least one post-bilateral motor assessment. This trial is registered at ClinicalTrials.gov, NCT04728295 and is active, not recruiting. Between July 12, 2021, and Nov 1, 2023, 54 patients received unilateral treatment and 40 proceeded to bilateral treatment (63 [67%] were male and 31 [33%] were female) and were included in the primary analysis; 36 completed 12-month follow-up after the second procedure. Median bilateral ULE motor scores decreased from 33\u00b70 points (IQR 28\u00b70-40\u00b75) at baseline to 21\u00b70 points (15\u00b70-25\u00b75) at month 3 post-bilateral treatment, a median within-patient change of 10\u00b75 points (5\u00b77-20\u00b70), representing a 32% (18-52) improvement (p<0\u00b70001). Benefits became apparent within 1 month of the first procedure and lasted through to 12 months after the second procedure. Treatment-related adverse events occurred in 21 (39%) of 54 patients after unilateral treatment; one (2%) had a persistent moderate adverse event at 6 months. After bilateral treatment, 22 (55%) of 40 patients had treatment-related adverse events; ten (25%) had persistent moderate or severe adverse events at 12 months, mainly affecting speech, gait, and balance. One (3%) patient developed severe persistent anarthria. Unilateral MRgFUS pallidothalamic tractotomy demonstrated safety and efficacy for Parkinson's disease motor complications; however, bilateral treatment offered small motor gains while increasing persistent moderate or severe adverse events. Post-bilateral treatment complications in speech, gait, and balance are consistent with historical data for bilateral ablative procedures for movement disorders. Although unilateral MRgFUS pallidothalamic tractotomy was beneficial in our study, bilateral procedures demand rigorous patient selection and counselling regarding cumulative risks. Insightec.",

Although most individuals with ALS reside at home, existing US guidelines primarily address clinic-based care and provide limited direction on medically necessary home health services and durable medical equipment (DME). The objective of this task force was to develop expert consensus guidance defining minimum medical standards for home health services and DME for individuals with ALS, with the goal of improving patient outcomes, safety, and quality of life. This guideline was developed by a multidisciplinary task force convened by the American Association of Neuromuscular and Electrodiagnostic Medicine (AANEM). The process incorporated a scoping literature review, stakeholder engagement (patients, caregivers, and advocacy groups), and iterative expert consensus. Recommendations were informed by clinical expertise, patient-centered priorities, and existing policy frameworks. This guideline outlines stage-responsive home healthcare recommendations spanning nursing, home health aides, physical and occupational therapy, speech-language pathology, respiratory therapy, nutritional support, and social work. It emphasizes proactive, anticipatory care aligned with the predictable trajectory of ALS, rather than being reactive based on functional decline. The document defines medically necessary DME across domains, including mobility, communication, respiratory support, and activities of daily living, advocating for timely access independent of restrictive payer criteria. Key principles include coordinated interdisciplinary care, continuous reassessment, caregiver support, and integration of palliative care. These recommendations establish a foundational standard for ALS home-based care in the United States.

While progress has been made in developing blood-based biomarkers for the early detection of amyloid pathology, amyloid positivity alone does not reliably predict progression to symptomatic disease. Digital markers can serve as complementary prognostic tools to inform early intervention strategies. Among digital markers, speech-based markers offer a scalable, non-invasive, and cost-effective approach to predicting and monitoring cognitive decline. However, the development of validated speech-based tools has been constrained by the lack of large, multilingual datasets with longitudinal sampling, deep phenotyping, harmonized clinical and biomarker data, and adequate representation of preclinical populations. SpeechDx is a 3-year, multinational, multilingual observational study (n\u00a0=\u00a02006) designed to address these gaps and accelerate the development of speech-based tools to inform early risk assessment, enable timely intervention, and guide personalized care.",

The patient participated in a comprehensive physiotherapy programme that included transfer training and promotion of independence in activities of daily living while also targeting rigidity and tremors. This case illustrates the diagnostic difficulties associated with addressing motor impairments, fall prevention and improving quality of life in a condition with few treatment alternatives.",

However, at least half of patients are unable to reach the recommended\u2009\u2265\u20094\u00a0h daily NIV use, and current NHS services provide insufficient follow-up for intensive optimisation. Delivering Effective Non-Invasive ventilation in Motor neuron disease using intensive remote support (DENIM) is a stepped-wedge cluster randomised trial. This protocol describes a process evaluation embedded within DENIM aiming to understand how and why the implementation strategy works (or does not work) across different contexts. The process evaluation employs a convergent mixed-methods multiple-case study design across twelve NHS ventilation services. We developed a programme theory informed by Normalization Process Theory (NPT), the Consolidated Framework for Implementation Research and Expert Recommendations for Implementing Change, which states how the DENIM implementation strategy is expected to achieve normalisation of evidence-based NIV practice. Data collection across twelve sites include: ethnographic observations of patient-staff interactions; semi-structured interviews with staff (n\u2009=\u200924-48) and patients/carers (n\u2009=\u200924) exploring implementation experiences; the NoMAD questionnaire measuring normalisation perceptions from healthcare professionals within the services and NIV adherence data from participants' ventilators. Barriers and facilitators to research participation for underserved populations including ethnic minorities, those with low digital literacy, and women over 80 with bulbar onset disease will also be identified. Qualitative data will be analysed using NPT-informed thematic analysis. Integration occurs at three levels (design, methods, interpretation) with joint display tables presenting quantitative and qualitative findings alongside meta-inferences. This process evaluation will generate explanatory insights into how implementation strategies can address the evidence-to-practice gap in complex, technology-supported care for progressive diseases, with implications for health equity and wider NHS digital transformation.

        "42329964": "ID: 42329964\nTitle: Applications of electromyography in Amyotrophic Lateral Sclerosis: A systematic review.\nAbstract: This systematic review examined the use of surface electromyography (sEMG) for the neuromuscular assessment of individuals with Amyotrophic Lateral Sclerosis (ALS), focusing on clinical parameters, the muscle groups evaluated, acquisition protocols, technical properties of the recording systems, integration with other technologies, and signal processing strategies. We included observational studies that applied sEMG to individuals diagnosed with ALS, with or without comparison to healthy controls, and without restrictions on publication year. The analyses included signals recorded at rest and during voluntary contractions, with or without the use of biofeedback. Most studies employed conventional or high-density surface electrodes, with sampling frequencies ranging from 500 Hz to 3000 Hz. The results showed that the primary parameters assessed were muscle fatigue, fasciculation patterns, the number of motor units (MUNE/MUNIX), motor unit firing rates, and signal complexity. These parameters demonstrated sensitivity to disease progression and may contribute to early diagnosis, phenotypic stratification, and functional monitoring of ALS. Additionally, the studies highlighted the increasing use of advanced computational approaches, such as machine learning, for feature extraction and automated classification. In conclusion, sEMG is a promising tool for functional assessment in ALS, with the potential to improve diagnostic accuracy and support new therapeutic strategies based on electrophysiological biomarkers. However, despite technological advances, the included studies displayed substantial methodological heterogeneity and limited protocol standardization. Integration with other neurophysiological modalities also remains underexplored, despite its significant clinical potential.",

The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech\u2011derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1\u2011weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS.",

Aim of this study is to assess the tolerability, safety, and effectiveness of adding a sigh cycle to non-invasive mechanical ventilation (NIMV) settings in ALS patients. In this randomized, blind-controlled proof-of concept study, 44 consecutive ALS patients with indication for NIMV were randomized to: Group I: NIMV with Sigh cycles; Group II: NIMV without Sigh. The primary outcome was the reduction in the Oxygen Desaturation Index (ODI); secondary outcomes included: Overnight Oximetry (OvOx), Arterial blood gas (ABG), and Visual Analog Scale (VAS; 0-10) scores to assess sleep quality, symptom intensity, mask interface, and NIMV tolerance. Assessments were conducted at baseline, after NIMV adaptation (T1) and at 1-month follow-up (T2). The Sigh cycle was safe and well tolerated. No significant group differences were observed at T1 or T2 in the primary outcome ODI (median \u0394ODI: Group A:-4.2; Group B:-4.6: p\u2009=\u20090.54), as well as in the OvOx parameters and pO2 and pCO2 ABG values. At T2, secondary analysis showed a significant difference in HCO\u2083- in favor of the Sigh arm (\u0394HCO3 -: -1.60 vs. 1.35\u2009mmol/L, p\u2009=\u20090.042). Exploratory Cox-regression models suggested a potential independent effect of SIGH on survival. Sigh is safe, well tolerated in ALS patients. Although this study did not reach the primary outcome, we also cannot rule out that sigh doesn't benefit the patient.",

Gastrostomy is a standard intervention to provide long-term nutritional support, yet its efficacy in stabilising nutritional status and preventing post-procedure weight loss is uncertain. This study explored factors influencing weight change post-gastrostomy. This multicentre, prospective observational cohort study was conducted across 17 UK sites and involved longitudinal assessments at placement (M0) and at three (M3), six (M6), and nine (M9) months. Data collection included nutritional, clinical and functional parameters. The primary outcome was the percentage weight change between M0 and M3. Secondary outcomes included nutritional intake, functional decline, and survival. Statistical analysis employed hierarchical logistic regression to identify independent predictors of weight change post-gastrostomy. Successful gastrostomy was performed in 155 included participants, of which 64 had complete M0 and M3 weight data. Mean percentage weight change from M0 to M3 was -3.3% (SD 7.4%), with 51.6% losing >1 kg in the first three months (p<0.01). Amongst those with available dietary data weight loss (n=21/43) was associated with lower mean daily energy (1620 kcal vs 2022 kcal, p=0.017) and protein intake (64g vs 77g, p=0.048) compared to those who maintained stable or gained weight (n=22/43). At M3, 50% (n=29/58) used a combination of oral and gastrostomy intake, 27.6% (n=16/58) used gastrostomy only, and 22.4% (13/58) were not using the gastrostomy. Based on available data for total daily expenditure energy expenditure (TDEE) calculation (n=39), 61.5% did not meet predicted total daily energy expenditure. Participants who lost weight (>1kg) post-gastrostomy had shorter median survival (270 days) compared to the weight stable/gain group (p=0.018). Hierarchical logistic regression suggested that mean daily water intake may potentially be an independent predictor of weight maintenance or gain, though this finding should be considered exploratory due to the limitations of our study (OR=1.003, p=0.040). Despite gastrostomy placement, over half of participants in our final analytical cohort continued to lose weight. For a smaller subset of participants, for whom nutritional intake were available, this was potentially due to insufficient energy, macronutrient, and fluid intake, alongside disease-specific catabolism. As post-gastrostomy weight loss negatively impacts survival, these findings highlight a need for proactive, tailored, and ongoing nutritional support and monitoring, to optimise post-gastrostomy outcomes and survival in ALS.",

Recent research highlights the potential role of gut microbiota and diet in modulating these symptoms, suggesting a complex interaction between nutrition, intestinal health, and presence of anxiety and depression in ALS patients. This study aims to investigate the relationship between dietary intake, gut microbiota composition, and presence of anxiety and depression in patients with amyotrophic lateral sclerosis (ALS). A cross-sectional study conducted with a sample of 48 patients with bulbar-onset or spinal-onset ALS from different regions of Spain. Dietary intake was assessed through 24-h records and food frequency questionnaires, while anxiety and depression were evaluated using validated scales that formed a latent factor called emotional distress. Stool consistency was assessed following the Bristol Stool Scale and the abundance of bacterial microbiota was quantified. Confirmatory factor analysis identified a nutritional factor composed of vitamins B1, B2, B9, C, and fiber, revealing a significant inverse association with anxiety and depression levels. The predictive model revealed both direct and indirect effects of this factor on presence of anxiety and depression, mediated by Bacteroides abundance and stool consistency. This model explained 19% of the variance in psychological distress. Our findings suggest that a diet rich in B vitamins, C vitamin and fiber may help improve emotional well-being in patients with ALS, highlighting the importance of nutritional strategies, as well as the role of Bacteroides related to stool consistency in patients with ALS.",
        "42339846": "ID: 42339846\nTitle: Single-O2ligation of hemoglobin links aerobic and anaerobic metabolism.\nAbstract: Oxygen (O2) binding and release by hemoglobin (Hb) are governed by cooperative interactions among its four subunits. During incremental workload exercise, femoral venous oxyhemoglobin (O2Hb) saturation exhibits a reproducible, momentary increase at the gas exchange threshold-coinciding with the inflection point of the in vivo O2 non-equilibrium curve (ONC). This suggests a transient shift in Hb's binding dynamics. We hypothesized that at this threshold, Hb tetramers carrying \u22641 bound O2 become predominant. In this state, the last bound O2 promotes further cooperative binding, but its release confers no cooperative advantage for unloading, biasing toward O2 rebinding. Using the O2 equilibrium curve models of Dash et al. (2016) and Adair, we computed the distribution of Hb's O2 ligation states across 12 pooled mean femoral venous blood samples from incremental workload cardiopulmonary exercise testing of five healthy male participants. At the gas exchange threshold-where the ONC inflects and flattens-tetramers with \u22641 O2 indeed dominated. This ligation-state distribution is consistent with Perrella et al.'s (1999) cryogenic resolution of native human Hb, which shows that carbon monoxide-ligated Hb tetramers peak at ~15-20% saturation, matching femoral venous ranges at the gas exchange threshold. Our results suggest that, at sufficiently low O\u2082Hb saturation, Hb may favor O\u2082 rebinding over cooperative unloading. We propose that glycolytic proton production and other Bohr effectors may counter this predicted binding bias supporting continued O\u2082 unloading. If confirmed, this mechanism unifies long-standing controversies in O2 transport physiology, framing the Hb-Bohr system as a proportional-integral controller of tissue oxygenation.",

This systematic review synthesised the literature on algorithmic and statistical models analysing cough acoustics for diagnosing or monitoring respiratory conditions. Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, five databases (PubMed, Embase, Scopus, Web of Science and CENTRAL) were systematically searched for studies published from January 2010 to June 2025. Eligible studies performed quantitative acoustic feature analysis of human coughs using statistical, machine learning or deep learning models and reported diagnostic or prognostic performance. 89 studies from 34 countries were assessed, covering cough detection (n=31), disease classification (n=55) and disease severity prediction (n=3), reflecting potential applications in disease monitoring. Deep learning approaches, especially convolutional and recurrent networks, were predominant (n=56) and tended to achieve the higher accuracies, although machine learning ensemble methods and logistic regression also demonstrated strong performance, particularly with well-engineered features. Across different diseases, sensitivities and specificities were often reported to be \u226590%, notably for tuberculosis, asthma and COVID-19. However, methodological weaknesses were common, with only 11.2% of studies introducing external validation, 71.1-87.6% demonstrating high risk of bias (according to PROBAST-AI) and most based on small, homogeneous or crowdsourced cohorts with limited generalisability. These limitations contribute to inflated internal performance and uncertainty about real-world applicability. Cough acoustic biomarkers hold promise as an adjunctive tool for screening and longitudinal monitoring in low-resource environments. Nevertheless, widespread implementation will require large, multicentre validation, standardised calibration, bias control and incorporation into privacy-preserving workflows.",

The Dimensional Apathy Scale (DAS) is widely used to assess these domains, yet no validated German version has been available. This study aimed to translate and validate the German DAS (G-DAS) in control participants (HC) and to characterize apathy profiles in German-speaking people with amyotrophic lateral sclerosis (pwALS). Seventy-seven HC and 32 pwALS completed self-rated and caregiver-rated measures of apathy, depression, disinhibition and executive dysfunction. The G-DAS was translated using a multi-round back-translation procedure. Psychometric validation was undertaken in the HC cohort. A subsample of HC matched to pwALS on age and sex was used for between-group comparisons and for deriving exploratory reference thresholds. The G-DAS demonstrated good to high internal consistency across subscales (\u03b1\u2009=\u2009.76-.85) and total scores (self-rated: \u03b1\u2009=\u2009.88; caregiver-rated: \u03b1\u2009=\u2009.86). Convergent validity was supported by significant correlations with the Apathy Evaluation Scale and Frontal Systems Behavior subscales, particularly for the Initiation and Executive subscales. Divergent validity was evidenced by the absence of associations with anxiety and depression. PwALS showed significantly higher Executive and Initiation apathy compared with matched HC, whereas Emotional apathy did not differ. Exploratory threshold scores derived from matched HC indicated that up to 47% of pwALS exhibited clinically elevated Initiation apathy. The G-DAS is a reliable and valid German-language measure of multidimensional apathy. It effectively captures the characteristic Executive and Initiation apathy profile in ALS, supporting its clinical and research utility.",

Mutations in the human superoxide dismutase 1 (hSOD1) gene, inherited in an autosomal dominant manner, lead to motor neuron degeneration in amyotrophic lateral sclerosis (ALS)-a fatal neurodegenerative disease with no effective treatment. In this study, we employed AAV9 to deliver to the SOD1G93A ALS mouse model artificial microRNAs targeting SOD1, embedded in dual miR-33 scaffolds driven by the promoter of the human survival motor neuron 1 (hSMN1) gene. A single intravenous injection achieved widespread and sustained suppression of SOD1, preserved \u03b1-motor neurons, maintained neuromuscular junctions (NMJs), and improved muscle function. These benefits are translated into significantly improved respiratory function, motor performance, and survival. Therapeutic efficacy was observed both when the treatment was administered pre-symptomatically and during symptomatic stages. Compared with previous AAV-based interventions, the survival benefit achieved in this IV delivery approach is unprecedented, supporting its potential for clinical translation in SOD1-linked ALS and other central nervous system (CNS) diseases caused by gain-of-toxicity gene mutations.",

This study aimed to investigate the relationship between clinical dysphagia assessment tools (EAT-10, GUSS, RSST, and sialorrhea severity) and videofluoroscopic swallowing study (VFSS) findings in patients with ALS. Materials and Methods: This retrospective observational study included 60 patients with ALS classified as spinal-onset (n = 38) or bulbar-onset (n = 22). Relationships between clinical assessments and VFSS findings were analysed using Spearman correlation analysis. Exploratory multivariable regression and receiver operating characteristic (ROC) analyses were performed to evaluate associations and aspiration risk discrimination. Results: Strong negative correlations were observed between PAS-Liquid and RSST and GUSS scores, whereas EAT-10 showed a strong positive correlation (all p < 0.001). ROC analyses demonstrated good discriminative ability for aspiration risk for GUSS (AUC = 0.89), RSST (AUC = 0.88), and EAT-10 (AUC = 0.82). Patients with bulbar-onset ALS demonstrated higher penetration-aspiration severity and lower functional oral intake. Conclusions: Clinical dysphagia assessment tools showed significant associations with instrumental swallowing findings in ALS. GUSS and RSST demonstrated good discriminative ability for aspiration risk and may be clinically useful bedside screening tools. However, instrumental swallowing assessment remains essential whenever feasible.",

Therefore, there is a critical need for non-invasive biomarkers that enable precise and accessible screening. In this study, we propose a multi-modal digital biomarker framework designed to accurately detect AD by evaluating impairments across multiple cognitive domains, such as language, working memory, and visuospatial attention. By leveraging voice and video data, our approach significantly enhances user accessibility and real-world applicability. We validated the proposed framework using a dataset of 128 participants, comprising 77 healthy controls (HCs) and 51 patients with AD. While individual cognitive tasks yielded F1-scores ranging from 69.23% to 77.78% and sensitivities from 69.23% to 80.77%, our ensemble strategy significantly enhanced detection performance, achieving an F1-score of 83.64% and a sensitivity of 88.46%. These findings confirm that the proposed multi-modal digital biomarker framework, enhanced via ensembling, provides a highly accurate, scalable, and practical solution for the non-invasive screening and detection of AD.",

Among these, ICI-related myocarditis, myositis and myasthenia gravis (MMM) overlap syndrome (ICI-MMM) is a rare but potentially fatal complication. Conventional immunotherapy often exhibits limited efficacy against ICI-MMM, which is associated with high mortality rates. Thus, there is an urgent need for novel and effective strategies to mitigate its life-threatening outcomes. We conducted a retrospective analysis of the successful rescue use of eculizumab in a patient with tislelizumab-related MMM overlap syndrome who tested seropositive for both anti-acetylcholine receptor (AChR) and anti-titin antibodies. We also performed a focused systematic literature review on the use of complement inhibitor therapy for ICI-related myasthenia gravis and its overlap syndrome. A 64-year-old male developed ptosis and tetraparesis two weeks following the second infusion of tislelizumab for lung adenocarcinoma. Serological testing revealed dual positivity for anti-AChR antibody and anti-titin antibody. Tislelizumab was immediately withdrawn, and the patient was treated with corticosteroids and intravenous immunoglobulin as first-line therapy. However, his clinical condition deteriorated rapidly, and new symptoms emerged, including chest pain, muscle pain, dysphagia, slurred speech, and dyspnea. Although the absence of histopathological confirmation for myocarditis and myositis, the clinical, laboratory, electrophysiological, and cardiac imaging findings supported the diagnosis of probable ICI-MMM. Rescue therapy with eculizumab was commenced (900 mg weekly for four doses), eliciting rapid and marked clinical improvement. The patient ultimately achieved minimal symptom expression without any exacerbation. This is the first reported case of successful eculizumab rescue treatment for probable tislelizumab-related MMM overlap syndrome with dual seropositivity. Our finding suggests eculizumab may represent a promising rescue option for ICI-MMM warranting prospective evaluation.",

How can the introduction of an organized, risk-adapted prostate cancer screening program in Germany shape preventive urology of the future? This narrative review article is based on guidelines and expert consensus supported by a\u00a0literature search in PubMed. The cited studies represent the most relevant work on this topic and were selected to illustrate developments and fundamental concepts; however, completeness is not claimed. Serum prostate-specific antigen (PSA) levels and prostate MRI not only identify patients at increased risk for prostate cancer but also offer insights into other urological conditions, such as lower urinary tract symptoms and hypogonadism. In analogy to other early detection strategies, PSA testing at the age of 45-50\u00a0years could serve as a\u00a0simple triage test to guide risk-adapted follow-up and timely referral to urological care. Lifestyle factors-including regular physical activity, a\u00a0balanced diet, and pelvic floor training-may favorably influence urological health and related outcomes. While organized prostate cancer screening has already been shown to improve cancer-specific mortality to a\u00a0level comparable to mammography, a\u00a0more holistic approach may further enhance its overall benefit. Urology has significant opportunities to actively promote healthy behaviors among aging men. The establishment of an organized prostate cancer screening program provides an ideal entry point for this purpose. Modern screening concepts should incorporate holistic health promotion for aging men alongside direct oncological endpoints.

This research used patient-reported data to identify the most prevalent and impactful symptoms experienced by individuals with PD and determine the demographic and clinical characteristics that are associated with higher symptomatic burden. We conducted semistructured qualitative interviews of 20 individuals with self-reported PD, obtaining 2,978 quotes regarding potential symptoms of importance. Findings from these interviews informed the development of a cross-sectional survey study designed to asess the impact of these symptoms in a larger cohort. Four-hundred four participants with self-reported PD participated in the survey study, providing the prevalence and relative importance (0-4 scale) of 301 symptoms representing 14 symptomatic themes. We subsequently performed subgroup analysis to identify demographic and clinical characteristics that were associated with a higher prevalence of symptomatic burden in PD. The most prevalent symptomatic themes identified by participants were sleep disturbances and daytime sleepiness (87.0%) and fatigue (84.7%). The symptomatic themes with the greatest impact (0-4) on participants' lives were fatigue (1.34) and sleep disturbances and daytime sleepiness (1.29). A higher prevalence of disease burden across all symptomatic themes was most strongly associated with speech impairment, gait freezing, and a duration of tremor greater than 5 years. The impact of PD on the lives of those living with this disease is multisystemic, reaching beyond the cardinal motor symptoms. Fatigue, sleep disturbances, and daytime sleepiness are highly prevalent and important to this population.",

In this controlled empirical comparison, we test whether spectrogram super-resolution (SR) at the feature level performed inside the model rather than via waveform resynthesis improves PD vs. healthy control (HC) discrimination under realistic constraints. Speech was recorded with a Microsoft HoloLens 2 using a standardized mixed-reality (MR) protocol from 161 speakers (75 PD/86 HC) across five tasks: Task 1 image description, Task 2 question answering, Task 3 story repetition, Task 4 sustained vowels, and Task 5 word repetition (DDK). Raw audio was exported as 48 kHz, 16-bit PCM, downmixed to mono, amplitude-normalized, conservatively trimmed for leading/trailing silence, and resampled to 16 kHz. Log-mel spectrograms (80 bins) were fed to practical ImageNet-pretrained backbones (ConvNeXt-Tiny, ResNet-50, EfficientNetV2-S). We compared six super-resolution (SR) strategies: identity, nearest (deterministic), bilinear SR, kernel/CARAFE-like SR, LIIF-like SR, and a frozen universal feature SR module (AnyUp) that upsamples intermediate feature maps. Evaluation used 5-fold, speaker-disjoint cross-validation with AUROC (AUC) and accuracy (ACC). AnyUp was the most consistent top performer, ranking first in 11/15 backbone-task cells. Gains were largest on tasks dominated by fine spectro-temporal cues: for ConvNeXt-Tiny, AnyUp vs. identity improved sustained vowels (Task 4) by \u0394AUC 0.030/\u0394ACC 0.070 and DDK (Task 5) by \u0394AUC 0.054/\u0394ACC 0.045. Macro-averaged over tasks, AnyUp outperformed identity by +0.025 AUC/+0.045 ACC (ConvNeXt-Tiny), +0.015/+0.027 (ResNet-50), and +0.052/+0.048 (EfficientNetV2-S). Representative best-in-class results include AUC/ACC of 0.899/0.886 (Task 4) and 0.927/0.897 (Task 5) for ConvNeXt-Tiny+AnyUp, and 0.940/0.903 (Task 5) for ResNet-50+AnyUp. Densifying spectrogram representations with a frozen, universal feature super-resolution module yields consistent, compute-efficient improvements in PD voice classification under MR-standardized acquisition, with the largest benefits on sustained vowels and DDK. The contribution is empirical rather than architectural: we compare practical representation-level SR choices rather than introduce a new SR module. Feature-level super-resolution is therefore a pragmatic alternative or complement to bandwidth extension when waveform synthesis is unnecessary. At a macro level, the observed accuracy gains (e.g., +0.045 for ConvNeXt-Tiny) suggest that representation-level SR may be operationally useful in low-resolution clinical-audio settings.",

We evaluated the Roche PD Mobile Application version 2, a smartphone-based platform, in 51 individuals with polysomnography-confirmed iRBD, 89 patients with early Parkinson's disease, and 22 healthy controls over 12 months. Participants completed daily active tasks generating validated digital summary measures. Adherence was high (73%). Baseline digital bradykinesia scores discriminated between groups (p\u2009<\u20090.001) and were higher in phenoconverters versus non-converters (p\u2009=\u20090.003; Cohen's d\u2009=\u20091.10). Over 50 weeks, bradykinesia (Cohen's d\u2009=\u20090.50) and speech (Cohen's d\u2009=\u20090.79) scores worsened significantly. Sample size modeling showed that digital bradykinesia required 132 participants per arm to detect a 50% treatment effect, fewer than the best-performing clinical measure. These findings support digital bradykinesia as a sensitive endpoint for prodromal Parkinson's disease trials.",

PD patients have motor and speech problems, so regular visits to and monitoring of the patients are hard. It is necessary to detect the presence of PD promptly and accurately, since early treatment will contribute greatly to enhancing patients' lives. As the number of aging people increases, there is a great demand for noninvasive, reliable, and remote diagnosis. In the current work, we studied 31 patients with PD and healthy subjects, their voice recordings, to create an automatic classification system. A Light Gradient Boosting Machine (LightGBM) classifier was adapted and boosted using metaheuristic-based feature selection (FS), namely the Pelican Optimization Algorithm (PAO). Hyperparameter optimization was made to optimize predictive performance. The models have been assessed on typical classification measures, i.e., accuracy, sensitivity, specificity, precision, and AUC. We classified using the baseline LightGBM classifier, with an accuracy of 95%. The resulting model had a better prediction accuracy of 97% after using PAO-based FS and hyperparameter optimization. More than that, the model was also sensitive, specific, precise, and had a high area under the curve, which validates its effectiveness at classifying PD. The paper shows that FS and hyperparameter tuning are effective approaches when applied to voice data and combined with LightGBM to detect PD as early as possible. The results point to the promise of noninvasive diagnostic systems based on the use of telemedicine to allow early intervention and enhance the lives of people with PD.",

However, the quantitative characterization of underlying age-related vocal tremor across the adult lifespan remains limited. This cross-sectional study investigated the characteristics of vocal tremor across the adult lifespan using automated acoustic analysis. A total of 291 native speakers aged 18-94 years were recruited and underwent perceptual voice evaluation and acoustic analysis during sustained phonation of the vowel /a/. Vocal tremor was quantified using digital signal processing, focusing on the prominence of fundamental frequency tremor (PF0T) and the prominence of amplitude tremor (PAT). A moderate-to-strong positive correlation between age and PF0T was observed in both males and females, indicating increasing instability of fundamental frequency with advancing age. In contrast, PAT did not show a significant age-related increase after correction for multiple comparisons. Perceptual ratings of tremor demonstrated only weak correlations with age but were moderately associated with acoustic measures of tremor. Normative models revealed that physiological tremor in healthy aging remains well below pathological thresholds reported in neurological disorders. These findings indicate that age-related vocal tremor is characterized predominantly by increasing instability of fundamental frequency rather than amplitude modulation, localizing the dominant age effect to laryngeal control of vocal fold tension rather than to respiratory drive. Automated acoustic analysis provides a sensitive and objective method for detecting subtle age-related vocal changes and may support future biomarker development for distinguishing physiological from pathological vocal tremor.",

VC is increasingly measured remotely in participants' homes, although in-clinic assessment remains the standard. We tested concordance between at-home and in-clinic VC to determine trial eligibility, track progression, and predict survival in a large ALS trial. At-home and in-clinic VC were assessed at baseline and approximately every 8\u2009weeks for a year in the first four regimens of the HEALEY ALS Platform Trial. At-home assessments were coached via live videoconference and centrally reviewed. VC measurements, expressed as percent of predicted normal (%PN), were compared cross-sectionally, longitudinally, and for predicting survival time. Data from 233 participants with 3-8 paired at-home and in-clinic VC assessments completed <\u200914\u2009days apart were analyzed. At-home and in-clinic VC were well correlated (Lin's rc\u2009=\u20090.82) with no systematic bias. At-home VC \u2265\u200960%PN predicted in-clinic VC \u2265\u200960%PN with a positive predictive value of 91% and a negative predictive value of 65%. VC slopes were moderately correlated (rc\u2009=\u20090.68). At-home VC progressed 28% faster than in-clinic VC with proportionately less variance (at-home [SE]\u2009=\u2009-1.882 [0.153] %PN/month, in-clinic\u2009=\u2009-1.476 [0.131] %PN/month). Slopes of at-home and in-clinic VC explained 15% and 17% of variation in future survival time, respectively. At-home and in-clinic VC were well correlated cross-sectionally. At-home VC performed well tracking longitudinal change and predicting survival. The reduced participant burden of assessment and concordance with in-clinic measurement support use of at-home monitoring of VC.",

A critical perspective on drug safety and disease vulnerability.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder with limited treatment options and diverse symptoms necessitating active management. Anticholinergic medications are frequently used in ALS care, particularly for sialorrhea and mood disturbances. Their cumulative effects, termed anticholinergic burden, may pose underrecognized risks in this neurologically vulnerable population. This review highlights a plausible safety signal and outlines priorities for future research. This narrative review synthesizes evidence from non-ALS populations reporting associations between higher anticholinergic burden and cognitive decline, respiratory complications, functional deterioration, and mortality. Evidence was identified through targeted PubMed/MEDLINE and Embase searches with reference chaining, emphasizing recent and seminal studies. Mechanistic overlap with ALS pathophysiology, including neuromuscular junction disruption, impaired cholinergic signaling, and neuroinflammation, supports biological plausibility for harm. Current ALS guidelines do not address cumulative anticholinergic exposure, leaving clinicians without a framework for evaluating risk or deprescribing. This article proposes a testable hypothesis that anticholinergic burden may represent a clinically relevant yet unmeasured risk factor in ALS. Emerging pharmacoepidemiologic methods and validated burden tools offer approaches to quantify exposure and evaluate relationships with ALS outcomes, supporting safer symptomatic management. Prioritizing longitudinal studies and integrating burden assessment into multidisciplinary care may help clarify risk.",

We examined fractional anisotropy (FA), mean diffusivity (MD), and number of streamlines (NoS) across five cerebellar pathways-the inferior, middle, and superior cerebellar peduncles, the input and Purkinje fibers, and the parallel fibers-in adolescents with (n\u2009=\u2009135) and without (n\u2009=\u20097276) a parent-reported ASD diagnosis. We further tested whether cerebellar dMRI measures differentially related to core ASD symptom domains of social communication and interaction (SCI) and restricted and repetitive behaviors (RRB). Group comparisons revealed significant differences in cerebellar NoS (Pillai's trace p\u2009=\u2009.033), driven by greater NoS of the superior cerebellar peduncle in early adolescents with ASD; FA and MD showed no significant group effects. Cerebellar pathway dMRI measures exhibited significant interactions with diagnosis in relation to ASD symptom severity. The superior cerebellar peduncle demonstrated the strongest diagnosis-dependent interaction effects, with the NoS showing markedly stronger associations with both social communication (\u0394\u03b2\u2009=\u20090.14, p\u2009=\u2009.0019) and restricted and repetitive behaviors (\u0394\u03b2\u2009=\u20090.21, p\u2009<\u2009.0001) in children with ASD. These findings highlight the superior cerebellar peduncle as a key pathway of structural variability and highlight dMRI measures of the cerebellar pathways as meaningful correlates of ASD symptoms in early adolescence.",

Pericardiocentesis was performed, with improvement in the clinical picture of heart failure, although residual dysphonia persisted upon discharge. Ortner syndrome or cardiovocal syndrome consists of paralysis of the left recurrent laryngeal nerve caused by a cardiovascular condition, usually and originally described by left atrial dilation in relation to rheumatic mitral valve disease. Early diagnosis can be useful to initiate immediate treatment and restore vocal cord function.

Immune modulatory drugs may show higher efficacy than anti-seizure drugs (ASD) in ESES. Our study aimed to determine the immune-modulatory treatment-responsive subgroups through assessment of neuroinflammatory mediators. The study included thirty-five consecutively diagnosed patients with treatment-resistant ESES, all under ASD treatment and the control group comprised 25 individuals diagnosed with primary headache disorders. Serum, peripheral blood and cerebrospinal fluid (CSF) samples were collected before commencement and after the 12-month follow-up of monthly intravenous immunoglobulin (IVIg)+ASD regimen. Serum and/or CSF levels of YKL-40, CXCL13, HMGB1, GFAP and NFL and NLRP3 and IL1\u03b2 gene expression levels in peripheral blood mononuclear cells (PBMC) were measured using ELISA and real time quantitative PCR, respectively. Seizures and ESES activity ceased in 20 (57.1%) patients with ESES. Under IVIg+ASD, CSF levels of YKL-40, CXCL13, HMGB1 and GFAP and serum levels of YKL-40 and HMGB1 were significantly reduced, whereas serum CXCL13, CSF NFL, PBMC NLRP3 and IL1\u03b2 levels remained comparable among groups. Enhanced baseline CSF CXCL13, CSF HMGB1 and PBMC IL1\u03b2 levels were associated with treatment resistance (n=15, 42.9%) in ESES. Levels of neuroinflammation markers were comparable among etiology subgroups (rolandic epilepsy, genetic abnormalities, cerebral palsy). IVIg treatment dampens the neuroinflammatory response and thus immune-modulatory treatment in combination with ASD may contribute to the improvement of ESES symptoms. CXCL13, HMGB1 and IL-1\u03b2 may serve as markers of immune-modulatory treatment response in ESES.",

Despite this, limited research has explored the experiences of adults living with voice disorders. This review synthesizes patient-reported experiences and impacts of voice disorders in adulthood. Six databases (PubMed, CINAHL, Web of Science, Embase, Cochrane, and Scopus) were systematically searched, and studies were screened using an established scoping review framework. The included studies were analyzed following recognized principles of qualitative meta-synthesis. From 3525 studies identified, six met study inclusion criteria and underwent thematic synthesis. Five overarching themes emerged: 1) My voice doesn't sound or feel like it used to; 2) My voice disorder has diminished my emotional well-being and self-confidence; 3) My voice disorder impacts my life participation; 4) Stigma hurts, support helps; 5) Living with my voice disorder means learning to adapt. Recurring themes surrounding psychosocial well-being and life participation restriction highlight the need for clinicians to develop counseling skills and knowledge of when and how to refer for additional support. Clinicians are urged to use a more holistic approach to voice assessment and treatment, acknowledging that the impacts of voice disorders often extend well beyond the larynx.",
        "42381876": "ID: 42381876\nTitle: From womb to words: the sex-specific interplay of fetal sex hormones and maternal mood on infant language development.\nAbstract: Language development is influenced by biological and environmental factors, including infant hormonal status and maternal mental health. Previous research on the role of infant sex hormones in language development focused on estradiol and testosterone, yet first evidence indicates that dehydroepiandrosterone (DHEA), the dominant fetal steroid hormone, may be a more sensitive biomarker for language development by shaping the organization of the developing brain. Concerning infants' language-learning environment, maternal well-being is a key factor, with maternal depressed mood postpartum, even at subclinical levels, negatively affecting language development, as depressed mothers engage less with their children and use less infant-directed speech. The present study examined the interplay of fetal DHEA levels and maternal mood at eight weeks postpartum on receptive language abilities at 12 months in boys and girls. Fetal DHEA levels were extracted from hair samples collected two weeks after birth (n\u00a0=\u00a058; 28 girls), allowing fetal hormone milieu quantification in the third trimester. Maternal mood in the subclinical depression range was assessed using the Edinburgh Postnatal Depression Scale. Children's receptive language abilities were assessed using the German version of the Bayley Scales of Infant and Toddler Development. Stepwise multiple linear regression analysis revealed fetal DHEA to predict language development in boys, with the effect depending on maternal mood. Only when mothers experienced better mood postpartum were higher DHEA levels related to lower language ability. By contrast, in girls, only maternal mood significantly contributed to language ability, with better mood relating to higher language outcome. Our findings suggest that the effect of infant sex hormones on language development follows sex-specific patterns and appears to be modulated by the learning environment. Moreover, our results emphasize the importance of mental support during the early stages of language development.",
        "42384108": "ID: 42384108\nTitle: Immune checkpoint inhibitor-induced myasthenia gravis and myocarditis: a fatal immune-related adverse event.\nAbstract: Checkpoint inhibitors, a class of immunotherapeutic agents, have transformed the oncology landscape by targeting immune checkpoints - regulatory pathways that modulate immune cell activity. By inhibiting proteins such as programmed cell death 1 (PD-1), programmed cell death ligand 1 (PD-L1), and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), these agents enhance the immune response against cancer cells. However, their efficacy comes at the cost of a range of immune-related adverse events (irAEs), including autoimmune reactions such as colitis, hepatitis, and endocrinopathies, which can range in severity from mild to life-threatening. We present the case of a 76-year-old man with cholangiocarcinoma on durvalumab, a PD-L1 inhibitor, who presented to the emergency department with shortness of breath, cough, and weakness. Workup led to the diagnosis of immune-related myasthenia gravis and a non-ST-elevation myocardial infarction (NSTEMI), the latter believed to be secondary to durvalumab-induced myocarditis. Initial treatment with intravenous immunoglobulin (IVIG) produced brief, partial symptomatic improvement but failed to resolve respiratory weakness or other bulbar manifestations. His condition deteriorated rapidly, progressing to respiratory failure within weeks of onset. Given the refractory nature of his disease course, he was subsequently treated with a repeat dose of IVIG and prednisone, then transferred to an outside facility for plasma exchange. Despite these interventions, the patient ultimately succumbed to his illness. This case highlights the rare but potentially fatal concurrent occurrence of immune-related myasthenia gravis and myocarditis as irAEs in a patient receiving durvalumab for cholangiocarcinoma. While checkpoint inhibitors have revolutionized outcomes across many solid tumor malignancies, this case underscores the diagnostic and management challenges posed by severe, refractory irAEs, and the importance of early recognition and aggressive treatment in this patient population.",

Machine learning speech analysis can detect motor and cognitive symptoms of HD, but not yet psychiatric symptoms. This study investigated whether speech analyses can detect the presence of psychiatric symptoms in HD. Audio recordings of six narrative tasks (cookie-theft picture description, red-riding hood storytelling, most recent 24 hours recalling, happy, sad, or angry storytelling) were prospectively collected from subsequent genetically confirmed HD participants from the BIOHD and REPAIR CAPIT-HD-Beta cohorts at the Hospital Henri-Mondor, Cr\u00e9teil. Speech therapists blindly annotated speech samples to allow extraction of three types of features: linguistic, LASER, and acoustic features. Psychiatric symptoms in participants were detected using the Problem Behaviors Assessment Short version (PBA-s). Machine learning classifier models were trained on 80% of the 89 participants before being tested on the remaining 20% of individuals. F1-scores were calculated and compared to chance. Linguistic features detected obsessive/compulsive behavior (OCB) with all but joy task, and best with the cookie task (F1-score: 0.67, confidence interval [0.47-0.86] (p\u2009\u2266\u20090.001)). They also best detected depression with the red-riding hood (F1 score 0.66, [0.45-0.87], p\u2009\u2266\u20090.001), apathy with the joy task (0.60, [0.39-0.81], p\u2009\u2266\u20090.001), but not irritability. LASER features best detected OCB (0.65, [0.45-0.84], p\u2009\u2266\u20090.001), depression (0.60, [0.40, 0.80], p\u2009\u2266\u20090.01) and apathy (0.61, [0.37, 0.86], p\u2009\u2266\u20090.001) from the red-riding hood task, but not irritability.

The current study aimed to examine the relationship between timely vocal response during parent-child interactions (i.e., the probability of mothers responding to their child within a specified time period and vice versa), and later psychiatric diagnosis. Drawing on data from the Avon Longitudinal Study of Parents and Children (ALSPAC) cohort, a case control study was conducted based on infant-mother video observations of children assessed for neuropsychiatric disorders using the parent-reported Development and Wellbeing Assessment (DAWBA) at seven years of age (103 controls and 55 cases). Empirical examination suggested that 1 second represented the optimal threshold for maternal responses and 8 seconds for child responses. Only the maternal measure was found to predict later psychiatric disorders, with evidence of associations limited to hyperactivity and conduct disorders. These associations were not sensitive to either maternal education or child sex. The results are discussed in terms of the value of precise interpretation of early mother/child interaction and for the potential for providing targeted intervention to the population concerned.",

Ultrasonography is considered the imaging modality of choice. It allows detailed evaluation of anatomical structures without radiation exposure and usually without the need for anesthesia. Proper patient positioning (dorsal recumbency with extended head), clipping and the use of a high-frequency linear transducer are essential. A systematic approach based on anatomical landmarks - starting at the larynx and trachea, proceeding to the salivary glands and lymph nodes to blood vessels - is crucial for accurate assessment. A thorough understanding of the physiologic sonographic anatomy of the neck structures is mandatory to identify pathological changes. Key evaluation criteria for cervical masses include location, size, extent, margins, echogenicity, echotexture and vascularity. For example, anechoic lesions typically indicate fluid-filled structures, while enlarged hypoechoic lymph nodes may suggest inflammatory or neoplastic processes. Abscesses usually appear as cavities with thick walls, and foreign bodies are clearly visible when they exhibit a smooth, linear, echogenic, sound-attenuating surface and are surrounded by fluid. Thyroid tumors are frequently large and heterogeneous, sometimes with mineralization. The differentiation between benign and malignant lesions, however, is not possible based on ultrasound alone. A major advantage of ultrasonography is the ability to guide interventions. Fine-needle aspiration or biopsy enables cytological or histopathological diagnosis. Additionally, foreign bodies can ideally be removed with minimally invasive procedures under ultrasound guidance. Umfangsvermehrungen im ventralen Halsbereich des Hundes stellen diagnostisch eine Herausforderung dar, da Ursprung und Ursache nach Erhebung der Vorgeschichte und der klinischen Untersuchung oft unklar bleiben. Die Sonografie erweist sich als initiale bildgebende Methode der Wahl. Sie erm\u00f6glicht eine detaillierte Darstellung von Strukturen ohne Strahlenbelastung und meist ohne Narkose. Voraussetzung ist die korrekte Lagerung des Patienten in R\u00fcckenlage mit gestrecktem Kopf, Scheren sowie die Verwendung eines hochfrequenten Linearschallkopfes. Eine systematische Untersuchung anhand anatomischer Leitstrukturen \u2013 beginnend beim Kehlkopf \u00fcber Trachea, Speicheldr\u00fcsen und Lymphknoten bis hin zu Blutgef\u00e4\u00dfen \u2013 ist entscheidend f\u00fcr eine sichere Orientierung.Kenntnis der normalen Sonoanatomie der Halsorgane ist Voraussetzung, um pathologische Ver\u00e4nderungen identifizieren zu k\u00f6nnen. Die Beurteilungskriterien bei Umfangsvermehrungen sind Lokalisation, Gr\u00f6\u00dfe, Ausdehnung, Abgrenzbarkeit, Echogenit\u00e4t, Echotextur und Durchblutung. So weisen beispielsweise anechogene L\u00e4sionen meist auf Fl\u00fcssigkeit hin, w\u00e4hrend hypoechogene, vergr\u00f6\u00dferte Lymphknoten entz\u00fcndlich oder neoplastisch ver\u00e4ndert sein k\u00f6nnen. Ein Abszess besteht typischerweise aus einer Kavit\u00e4t mit dicker Wand, Fremdk\u00f6rper sind gut erkennbar, wenn sie eine glatte, lineare, echoreiche, schallmindernde Oberfl\u00e4che aufweisen und von Fl\u00fcssigkeit umgeben sind.

Recent reductions in global health funding have threatened TB control, making comprehensive assessment of TB, HIV-related TB, and drug-resistant TB burdens before these disruptions essential for shaping effective responses. The WHO End TB Strategy sets targets of a 95% reduction in TB deaths and a 90% reduction in TB incidence between 2015 and 2035. Using results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023, this study aims to assess the burden of TB and multidrug-resistant TB (MDR-TB) across 204 countries and territories, and to evaluate progress towards the WHO End TB incidence and mortality targets. We quantified TB mortality using the Cause of Death Ensemble modelling platform with global vital registration, surveillance, verbal autopsy, and minimally invasive tissue sampling data. For TB morbidity estimation, we simultaneously modelled incidence, prevalence, and mortality by age and sex using DisMod-MR 2.1. A population attributable fraction (PAF) approach was applied to stratify morbidity and mortality estimates by HIV and drug-resistance status. We also calculated disability-adjusted life-years (DALYs) as the sum of years of life lost and years lived with disability. For the risk factor analysis, a comparative risk assessment framework was used and PAFs were derived for alcohol use, smoking, and high fasting plasma glucose to determine the proportion of TB burden associated with these risk factors. In 2023, there were an estimated 9\u00b711 million (95% uncertainty interval 8\u00b704-10\u00b73) incident cases of all-form TB, 1\u00b722 million (0\u00b798-1\u00b749) deaths, and 54\u00b76 million (43\u00b78-65\u00b75) DALYs globally. HIV-related TB comprised 781\u2008000 (690\u2008000-879\u2008000) incident cases and 210\u2008000 (142\u2008000-279\u2008000) deaths, contributing 11\u00b70 million (7\u00b756-14\u00b73) DALYs. MDR-TB accounted for 466\u2008000 (198\u2008000-1\u2008080\u2008000) incident cases, 102\u2008000 (31\u2008700-238\u2008000) deaths, and 3\u00b796 million (1\u00b731-9\u00b701) DALYs. From 2015 to 2023, global all-form TB incidence rates declined by 19\u00b72% (17\u00b78-20\u00b75) and deaths declined by 22\u00b76% (4\u00b77-35\u00b77); declines were larger for drug-susceptible TB than for MDR-TB. Sub-Saharan Africa and south Asia had the highest mortality burdens in 2023; reductions in all-form TB incidence and mortality were uneven between 2000 and 2023, with limited progress in both measures in Latin America and the Caribbean. Removing smoking, alcohol use, and high fasting plasma glucose would reduce global TB deaths to 768\u2008000 (592\u2008000-970\u2008000) and DALYs to 34\u00b79 million (27\u00b78-43\u00b78) in 2023; MDR-TB deaths would decrease to 77\u2008200 (23\u2008400-183\u2008000) and DALYs to 3\u00b712 million (1\u00b703-7\u00b729). Global progress towards WHO End TB targets is disparate and fragile. Although many regions achieved meaningful gains, others have stagnated in recent years. The complexity of TB prevention is amplified by divergent MDR-TB trends, the persistent burden of HIV, and growing exposure to modifiable risk factors. Recent volatility in global health financing threatens to further destabilise this vulnerable epidemiological landscape; concerted action is urgently needed to temper disruptions and preserve progress.

This experimental study evaluated a novel intraoperative neuromonitoring (IONM)-guided selective vagus-recurrent laryngeal nerve anastomosis (SVRA) technique and compared its immediate electrophysiologic performance with DA in a porcine thyroid surgery model. 18 transected nerves from 9 pigs were randomized to DA or SVRA (9 nerves per group). In the SVRA group, low-current IONM was used to map vagus nerve (VN) motor fibers innervating laryngeal musculature; these fibers were selectively dissected and anastomosed to the transected RLN. In the DA group, end-to-end RLN neurorrhaphy was performed under microscopy. Electromyography (EMG) amplitudes and latencies were recorded at baseline and serially up to 2 hours after anastomosis; hemodynamic parameters were monitored to assess the safety of VN manipulation. VN motor fibers innervating the laryngeal muscles were predominantly localized to the lateral VN and were mostly concentrated in a single strand. After anastomosis, both techniques yielded early EMG recovery, with post-anastomotic amplitudes often exceeding 50% of baseline. A cross-innervation model (left VN to right RLN) produced immediate EMG responses approaching baseline and bilateral vocal fold activation. Moreover, when the anastomosed nerve was pulled, the EMG amplitude varied with the alteration of the relative position of the fiber components at the two severed ends. VN dissection did not cause clinically relevant changes in blood pressure or oxygen saturation, and only minor, non-significant heart rate increases were observed. IONM-guided SVRA enables selective recruitment of VN motor fibers for targeted RLN reconstruction while largely preserving VN trunk integrity. These findings support SVRA as a physiologically grounded and technically feasible reconstructive option that can achieve acute electrophysiological recovery when tension precludes DA during thyroid surgery-related RLN transection, although long-term functional reinnervation remains to be established.",

Hearing loss has also been linked to altered brain responses to emotional non-speech sounds, potentially contributing to the speech emotion perception deficits even under aided listening. While fMRI requires hearing aid removal due to metal incompatibility, fNIRS is silent and hearing-aid compatible, creating a novel opportunity to identify neural processes during aided listening. We leveraged fNIRS to examine how hearing aids affect brain function in experienced hearing-aid users during speech emotion perception. Older adults (17 normal hearing, 14 hearing-aid users) judged vocal-emotion changes in speech while fNIRS recorded hemodynamic activity. Hearing-aid users completed the task under aided and unaided listening. Behaviorally, hearing aids did not improve speech emotion perception, replicating prior research. In cortical responses, individuals with hearing loss showed increased planum temporale activity, regardless of hearing-aid use. Unaided listening showed additional frontal recruitment, including increased medial superior frontal gyrus activity and stronger functional connectivity between inferior frontal and superior temporal gyri. Conversely, aided listening increased inferior parietal lobe activity, but reduced connectivity between inferior frontal gyrus and inferior parietal lobe. Together, findings indicate that hearing aids partially modify cortical processing of emotional speech. They reduced reliance on frontal compensatory control systems and increased engagement of a higher-order parietal region, consistent with partial restoration of bottom-up auditory information during aided listening. Persistent abnormalities in early auditory processing and incomplete sensorimotor integration may explain why hearing aids fail to normalize speech emotion perception.",

A key advantage of this approach lies in its ability to quantify aspects of the articulatory process that have not been previously explored in the context of depression, namely, predictability, complexity, and randomness. These properties are respectively characterised using the Largest Lyapunov Exponent, the Correlation Dimension, and the Sample Entropy. Thorough experiments were conducted on the Androids Corpus, a publicly available dataset comprising 64 speakers diagnosed with depression by clinicians and 54 control speakers with no reported history of mental health conditions. The results indicate that the proposed biomarkers effectively discriminate between the depressed and control speakers, as evidenced by the high Cliff's delta values across both read and spontaneous speech.",
        "42394813": "ID: 42394813\nTitle: Operational integrity screening for telemedicine workflows: an explainable motion and audiovisual coherence framework.\nAbstract: Teleconsultations are exposed to digital impersonation and synthetic media attacks that can alter identity, articulation, or consent evidence, introducing emerging AI-enabled biosecurity risks to digitally mediated healthcare workflows. We evaluate an explainable integrity control based on motion dynamics and audiovisual temporal coherence, designed for conservative operation at extremely low false alarm rates with auditable evidence reporting to support governance and risk-based escalation. Our contribution is a reproducibility-oriented evaluation protocol and an evidence atlas of temporally grounded cues, together with a staged fusion that supports scalable prescreening and targeted verification under platform-style degradations characteristic of real-world dissemination chains. Building on prior biomarker-oriented analyses of physiological and structural cues for synthetic media detection, this work advances toward a calibrated, deployment-oriented integrity control architecture optimized for operational screening in telemedicine workflows. We use the DeepFake RealWorld (DFRW) dataset with 46,371 clips (229.28\u00a0h), combining 4,186 Open-Source Intelligence (OSINT) samples and 42,185 controlled, systematically degraded variants emulating recompression, resizing, filtering, and recapture. On the held-out binary-labeled test split, descriptor fusion reaches an AUC of 0.91 and achieves a true positive rate (TPR) of 18.5% (95% CI 16.2-20.8) at a false positive rate (FPR) of 0.1%, compared with 6.2% (95% CI 4.8-7.6) for an Xception baseline fine-tuned on the DFRW dataset. Microbenchmarked latencies motivate a two-stage deployment with explicit abstention and a structured integrity report aligned with healthcare governance and post-incident auditing requirements. This study evaluates telemedicine-oriented integrity controls using a benchmark dataset and does not claim demographic or clinical subgroup generalizability. Before deployment in clinical workflows, the proposed approach requires broader validation across age groups, ethnic backgrounds, speech characteristics, capture conditions, and medical conditions that may affect facial motion, articulation, or voice production. Prospective subgroup validation and governance-oriented assessment should therefore be treated as necessary directions for future work.",

In the present study, we compared the immunohistochemical expression of Nkx2.2 in cases of Ewing's sarcoma, neuroendocrine neoplasms at different sites, and a small subset of other mesenchymal and nonmesenchymal tumors in order to assess its utility in their distinction. This descriptive retrospective study lasted for 14 months and investigated 60 cases, with 17 cases of Ewing sarcoma, 34 cases of neuroendocrine neoplasms and nine cases of other tumors. Hematoxylin and eosin and Nkx2.2 immunohistochemistry-stained slides of previously diagnosed cases were retrieved and reviewed. Nkx2.2 exhibited sensitivity of 88.2% and specificity of 53.4% in the diagnosis of Ewing's sarcoma. Nkx2.2 expression was also present in neuroendocrine neoplasms (especially those of gastrointestinal and pancreatic origins) with 52.9% sensitivity and 34.6% specificity. Other neuroendocrine neoplasms that were positive for Nkx2.2 included those of prostate, female genital tract, and larynx origins. Among other tumors, pleomorphic sarcoma and melanoma exhibited Nkx2.2 positivity. Most cases (83.3%, 5/6) of lung neuroendocrine neoplasms were negative for Nkx2.2. Nkx2.2 exhibited high sensitivity in diagnosing Ewing's sarcoma and certain neuroendocrine neoplasms (especially those of gastrointestinal and pancreatic origins), but its lower specificity and varied expression across other tumor types highlight the need for a cautious and context-specific approach when used in clinical practice. \u062a\u064f\u0639\u062f \u0633\u0627\u0631\u0643\u0648\u0645\u0627

        "42396248": "ID: 42396248\nTitle: Case Report: Extraforaminal endoscopic lumbar discectomy in two dogs with far-lateral intervertebral disc extrusions.\nAbstract: Far-lateral intervertebral disc extrusions (IVDE) represent an uncommon subset of intervertebral disc disease in dogs, in which disc material is herniated dorsolaterally or laterally to compress the exiting nerve root in an extraforaminal location. While minimally invasive spinal surgery techniques have been described in dogs, to the authors knowledge, full-endoscopic discectomy has not previously been reported for extraforaminal IVDE. This case report describes the clinical presentation, surgical technique, and short-term outcomes of extraforaminal endoscopic lumbar discectomy (EELD) in two dogs. Two middle-aged crossbreed dogs were presented with subacute onset of vocalization, pelvic limb lameness presumed to be a nerve root signature, and marked lumbar hyperaesthesia without other abnormalities on neurological examination. MRI or CT confirmed L5-6 extraforaminal disc extrusion with L5 spinal nerve root compression in both cases. Medical management failed to resolve clinical signs. Using a uniportal approach, a 6.3 mm diameter working-channel endoscope was fluoroscopically docked onto the transverse process of the vertebra caudal to the affected disc, creating a muscle-sparing lateral corridor. Extruded disc material was visualized, released from its fibrous capsule, and removed piecemeal without the need for osteotomy. Surgical times were 25 and 30 min. Post-operative CT confirmed effective decompression in both dogs. Post-operative recovery was rapid, with low pain scores and no requirement for opioid analgesia. Dogs were discharged within 24 h, and by 3 weeks both were free of lameness and spinal pain. At 12 weeks, caregiver-reported outcomes demonstrated sustained improvement, including a substantial reduction in Canine Brief Pain Inventory scores. EELD provided effective decompression through a minimally invasive corridor with excellent early outcomes. This first description in dogs supports further investigation of EELD as an alternative to conventional open surgical approaches for extraforaminal IVDE.",
        "42396380": "ID: 42396380\nTitle: A pilot study on AI-based voice analysis for monitoring patients hospitalized with acute decompensated heart failure.\nAbstract: Monitoring pulmonary congestion in chronic heart failure (HF) reduces decompensation and hospitalization, but conventional methods such as weight and symptom tracking are often unreliable. As fluid accumulation affects the lungs and vocal tract, subtle voice alterations may serve as a non-invasive signal for early detection of worsening HF. The Voice Analysis for Monitoring Patients with HF trial (VAMP-HF, NCT06566911) prospectively enrolled 104 patients hospitalized with acute decompensated HF (ADHF) across two academic centres in the USA and Germany. Daily voice recordings were collected from admission to discharge, with breathing features extracted from speech and acoustic features from sustained vowels. A machine-learning model was trained to classify recordings as admission-phase vs. discharge-phase using leave-one-patient-out. Patients with clinical deterioration, insufficient audio quality, or short length of stay were excluded. Seventy-nine patients were included in the final dataset. The model classified admission and discharge with an F 1-score of 0.83 (95% CI: 0.77-0.90; AUC = 0.90). In patients with higher audio volume (N = 54), performance reached 0.89 (95% CI: 0.82-0.94; AUC = 0.91). When applied to intermediate hospitalization days, model-predicted scores showed progressive increases from admission towards discharge. Performance remained robust irrespective of significant weight loss during hospitalization. In this pilot study, structured voice and breathing analysis discriminated hospitalization phase from admission through discharge in patients with ADHF. This non-invasive approach captured progressive changes during the hospital course and warrants further investigation with concurrent objective congestion markers to establish physiological specificity.",
        "42397370": "ID: 42397370\nTitle: [A Comprehensive Regional Rehabilitation Program for Children with Hearing Impairments with Active Parental Involvement: The Ivanovo Region Experience].\nAbstract: The problem of hearing impairment in children remains of high medical and social significance, as it negatively affects speech development, social adaptation, and quality of life. Early rehabilitation plays a crucial role, and parental involvement is a key factor in success. In the Russian Federation, ear diseases account for 5% of the structure of childhood disability, necessitating the development of accessible regional rehabilitation programs with active family involvement. To present a comprehensive regional rehabilitation program for children with hearing impairments in the Ivanovo region, developed with the support of the National Medical Research Center for Otorhinolaryngology of the FMBA of Russia, and to describe its main modules aimed at actively involving parents in the process of hearing restoration, speech development, and social adaptation of the child. This work is based on an analysis of the experience of implementing the regional program at the audiology department of the Ivanovo Regional Clinical Hospital with the participation of the Department of Otorhinolaryngology of Ivanovo State Medical University. The description is based on program documentation, session protocols, and interviews with participants (specialists and parents). A qualitative and descriptive analysis was conducted, identifying key modules, rehabilitation stages, and the roles of specialists. The program includes comprehensive diagnostics (audiological, speech therapy, psychological), an individualized rehabilitation plan, and a differentiated approach for users of hearing aids and cochlear implants. Educational modules for parents have been developed: psychological education, training in device handling, communication strategies, parental coaching, psychological support, social navigation, monitoring, and supervision. Innovative components include theater therapy and vocal lessons, which contribute to the development of prosody and strengthen parent-child relationships. The program is implemented by a multidisciplinary team (audiologist, ENT physician, speech-language pathologist, psychologist, social worker, coordinator) in accordance with a calendar model (0-1 month, 1-6 months, 6-24 months, preschool and school stages). Distance learning formats are provided for families from remote areas. The regional program of the Ivanovo region represents an example of a comprehensive family-centered approach that integrates modern evidence-based rehabilitation methods. This experience can serve as a model for the development of similar programs in other regions. Further research will be aimed at quantitative evaluation of the effectiveness of the described modules. \u041d\u0430\u0440\u0443\u0448\u0435\u043d\u0438\u044f \u0441\u043b\u0443\u0445\u0430 \u0443

This study evaluated whether explainable machine learning applied to ECG features could identify autonomic markers for FDS-ES discrimination. ECG recordings from 125 patients with FDS (n\u00a0=\u00a083) or ES (n\u00a0=\u00a042) from two epilepsy centres were analysed. A number of heart rate, HRV, and morphological ECG features was extracted from interictal and preictal segments. Relative-change features were calculated by normalising preictal values to interictal baseline. Classification used Leave-One-Subject-Out Cross-Validation with mutual information filtering, SHapley Additive exPlanations (SHAP)-guided feature selection, class balancing, and hyperparameter tuning. Entropy-based HRV measures were the most consistent discriminative features. In FDS, Sample Entropy, Fuzzy Entropy, and Dispersion Entropy decreased significantly from interictal to preictal states, whereas no significant entropy modulation was observed in ES. Dispersion Entropy showed the strongest contribution across statistical testing, SHAP interpretation, and feature-selection stability. Classification was limited in the interictal condition, and the best performance was obtained using relative-change features: XGBoost achieved 73.5% sensitivity (95% confidence interval [CI]: 62.7-82.6%) and 61.9% specificity (95% CI: 45.6-76.4%). FDS was associated with preictal reduction in HRV entropy, indicating more regular, less complex cardiac dynamics. Within-subject changes appeared to provide more discriminative than static ECG features. Although current performance does not support standalone diagnostic use, entropy-based HRV measures offer interpretable peri-ictal autonomic markers, suggesting visceral changes contribute to FDS emergence.",

This retrospective observational cohort study included patients with ALS followed by a multidisciplinary palliative care team between 2018 and 2020. Patients were classified according to gastrostomy status (RIG vs no RIG). Clinical data, respiratory support, nutritional status and survival outcomes were collected from medical records. Survival was analysed from gastrostomy indication using Kaplan-Meier curves stratified by baseline non-invasive ventilation (NIV) use. Among 155 patients with ALS, RIG was indicated in 53 and performed in 45; eight patients died before the procedure. 65 patients did not undergo gastrostomy. Median survival after RIG was 14.7 months, compared with 8 months in non-RIG patients who died. Baseline NIV use was associated with longer survival. No major safety concerns were identified. RIG appears to be a safe and feasible option in advanced ALS. Multidisciplinary care with integrated palliative involvement may facilitate referral, optimise nutritional support and support shared decision-making aligned with patients' goals of care. Further prospective studies are needed to confirm benefits and identify intervention timing.",

Among these, dysphagia management is crucial, as safe and efficient swallowing depends on the coordinated action of neuromuscular and anatomical structures within the oropharyngeal, laryngeal, and esophageal systems. Disruption of this coordination, particularly after prolonged intubation, can lead to aspiration, malnutrition, and reduced quality of life. To review the literature on swallowing disorders following prolonged intubation, identify associated risk factors, and describe the main Speech-Language Patathology (SLP) assessment and intervention strategies. A systematic review was conducted on swallowing disorders after prolonged endotracheal intubation using PubMed, BVS, and Cochrane databases. Following PRISMA 2020 guidelines, 266 articles were identified, of which 16 met the inclusion criteria. Risk of bias was assessed with the ROBINS-I and Newcastle-Ottawa (NOS) scales. Most studies showed low risk of bias and moderate methodological quality. Prolonged intubation was consistently associated with dysphagia. Key risk factors included advanced age, neurological conditions, tracheostomy, inflammation, pneumonia, poor functional status, and extended ICU (Intensive care unit) or hospital stays. Dysphagia after prolonged intubation results from multifactorial influences that compromise the swallowing mechanism. Early assessment and targeted Speech-Language Pathology significantly improve swallowing safety, accelerate recovery, and enhance patients' quality of life. These findings highlight the essential role of Speech-Language Pathology (SLP) in post-extubation care and the importance of standardized assessment and rehabilitation protocols.",

However, some autistic subgroups, particularly minimally verbal children, children with low expressive-language ability, and those with suspected co-occurring speech-motor difficulties, may show atypical vowel-acoustic patterns. Because vowel production can be quantified through measures such as formant frequencies, vowel-space area, duration, and variability, these parameters may offer useful objective information for characterizing speech impairment and informing rehabilitation planning in selected phenotypes. This narrative review critically examined the literature on vowel-acoustic characteristics in autistic children and their possible relevance to rehabilitation-oriented systems. Structured searches of PubMed, Scopus, and Web of Science were conducted for studies published up to September 2025. Evidence suggests that some autistic subgroups may exhibit reduced vowel distinctiveness, greater acoustic variability, and atypical temporal or dynamic speech features, although findings are heterogeneous and do not support a single uniform acoustic profile across ASD. Direct intervention evidence remains limited. Most rehabilitation-related studies are small, exploratory investigations, and the available literature is concentrated largely around Auditory-Motor Mapping Training (AMMT), an indirectly relevant speech-motor intervention that reports vowel-related outcomes but does not directly target vowel-acoustic parameters in isolation.Overall, vowel-acoustic measures are better regarded as candidate quantitative tools for subgroup characterization, monitoring, and rehabilitation planning rather than as universal biomarkers across ASD. Their translational potential is promising but remains insufficiently validated, requiring stronger longitudinal, mechanistic, and intervention research before broad clinical application can be justified.",

While several studies assessed PEG indications, outcomes, and prognostic factors, there is no evidence regarding ALS patients' perspectives and health-related quality of life (HRQoL) associated with PEG. This study included 48 consecutive ALS patients. At the 1-month follow-up after PEG, patients and their caregivers completed a PEG satisfaction questionnaire regarding their decision to proceed with the PEG-tube placement. HRQoL was assessed using the Gastrointestinal Quality of Life Index (GIQLI) and the Short Form-36 (SF-36). In total, 77.1% of patients and 88.9% of caregivers confirmed that they would prefer to have a PEG tube placed again if required (p\u202f>\u202f0.001); 93.8% of patients felt that PEG made feeding easier, exerting a positive effect on overall wellbeing (83.3%) and increasing survival rates (93.8%) (p\u202f>\u202f0.001); 54.2% felt that PEG was cosmetically acceptable. Consistent positive rates were reported by caregivers. The GIQLI digestion subscale values significantly improved from baseline (28.3; SD\u202f=\u202f6.6) to discharge (30.97, SD\u202f=\u202f5.84) and were maintained at 1-month follow-up (30.21, SD\u202f=\u202f6.7; p\u202f=\u202f0.014). Conversely, in follow-up assessments, we observed a significant reduction in the SF-36 physical component summary (PCS) subscale (baseline\u202f=\u202f33.3; 1-month follow-up\u202f=\u202f28.61; p\u202f=\u202f0.032), which was accompanied by a significant worsening in the GIQLI physical dimension subscale (baseline\u202f=\u202f9.63; 1-month follow-up\u202f=\u202f7.38; p\u202f=\u202f0.044).

Among various behavioral biomarkers, speech-based features have gained increasing attention in depression detection due to their non-invasive nature, affordability, and rich capacity for conveying affective states. However, conventional depression recognition approaches rely solely on unimodal acoustic representations and largely overlook the influence of emotion and gender. To address this limitation, this study proposed a gender-emotion interaction multi-task network(G-EIMTNet) for depression recognition via transformer-based cross modal fusion. In the feature fusion stage, the deep representations of Mel-spectrograms were extracted using convolutional neural networks(CNN), and then the Maximum Correlation Minimum Redundancy (MRMR) algorithm was employed to select acoustic higher-order statistical features that were highly correlated with emotions and depressive states. These two types of features were then fused through the transformer attention mechanism. In the depression recognition stage, a depression recognition network for the interaction between gender and emotion was constructed based on a multi-task framework. Experiments on the AVEC2014 dataset showed that this approach outperformed the baseline model by 15.88% and 14.73% in accuracy and F1 score, respectively. Ablation experiments verify the effectiveness of multi-modal fusion and gender-emotion interaction.",

Advanced therapeutic strategies, including FcRn antagonists and C5 complement inhibitors, have demonstrated early and sustained clinical efficacy in pivotal phase 3 trials. However, evidence supporting their early use in complex clinical scenarios remains limited. We report two cases of severe generalized MG in which early initiation of advanced therapies was associated with rapid clinical stabilization. In the first case, a 75-year-old man with thymoma-associated MG and severe bulbar involvement refractory (MG-ADL: 11) to plasma exchange (PLEX) and intravenous immunoglobulins (IVIg), and unable to continue azathioprine due to adverse events, received off-label efgartigimod preoperatively. Near-complete resolution of bulbar symptoms was observed within 48 hours, enabling robot-assisted thymectomy on day 4 following the first infusion, with sustained neurological improvement at one-month follow-up (MG-ADL score: 2). In the second case, a 74-year-old man with severe refractory bulbar MG requiring nasogastric tube feeding (MG-ADL: 13) and subsequent percutaneous endoscopic gastrostomy (PEG) was treated with ravulizumab after an incomplete response to PLEX, IVIg, corticosteroids, and azathioprine. MG-ADL decreased from 9 at treatment initiation to 5 after two infusions of ravulizumab, and complete recovery of swallowing function allowed PEG removal at 18-week follow-up, with achievement of minimal symptom expression (MG-ADL score: 0). These cases highlight the potential role of early and targeted use of advanced immunotherapies in severe, refractory MG, including as a bridging strategy to thymectomy. Further prospective studies are needed to define optimal criteria and timing for early integration of these agents into the therapeutic algorithm.",

Among these, personality traits such as neuroticism have been linked to heightened symptom perception and disability. However, few studies have systematically examined the relationship between neuroticism, functional burden, and diagnostic characteristics in a population with clinical dizziness.ObjectiveTo investigate the relationship between perceived dizziness-related handicap and neuroticism as a personality trait among patients referred to a multidisciplinary dizziness and balance clinic.MethodsThis observational study included 247 adult patients with persistent dizziness referred to a specialist clinic. Patients completed the Eysenck Personality Questionnaire (EPQ) and the Dizziness Handicap Inventory (DHI). Clinical data included diagnosis category, duration of symptoms, fall history, comorbidities, and consultation history. Statistical analyses included Spearman correlations, ANOVA, chi-square tests, cluster analysis, and multivariate linear regression.ResultsNeuroticism was significantly correlated with higher DHI scores (\u03c1 = 0.39, p < 0.001) and a greater number of healthcare consultations (\u03c1 = 0.19, p = 0.003). It was not associated with duration of symptoms or fall history. A chi-square test indicated a significant association between the neuroticism category and diagnosis category (\u03c72 = 32.02, p = 0.043), with higher neuroticism observed in functional and central disorders. Cluster analysis revealed three psychological-clinical subgroups varying in emotional burden, functional disability, and comorbidity profiles. In regression modelling, neuroticism was the only significant predictor of DHI score (p < 0.001), independent of diagnosis or symptom duration.ConclusionPersonality domains, especially neuroticism, are strong predictors of perceived functional burden in patients with chronic dizziness. These findings underscore the importance of incorporating psychological assessment into the clinical evaluation to further facilitate tailored interventions for the management of dizziness. Personality profiling may help identify high-burden subgroups and guide individualized, multidisciplinary care strategies.",

Prospective cohort study. Tertiary referral center. From December 2021 to June 2024, ECochG was measured intraoperatively using the Active Insertion Monitoring (AIM) system by Advanced Bionics. After insertion, multifrequency tone bursts were delivered via a sound tube from 250\u2009Hz to 2\u2009kHz at 95 to 105\u2009dB HL with recordings at each internal electrode. Using spectral analysis, the maximal amplitude (MA) response electrode was identified by frequency and summed into a single value of total response (MA-ECochG-TR). Postoperative CI performance was routinely monitored. Of 57 participants with ECochG recordings, 43 completed 6-month testing. Of these, 23 were perimodiolar (Mid-Scala [MS]), and 20 were lateral wall (SlimJ [SJ]). MA-ECochG-TR had a moderately strong positive correlation to 6-month consonant-nucleus-consonant (CNC) word scores for MS cases (r\u2009=\u20090.73, 95% CI [0.46-0.88], P\u2009<\u2009.001), but showed no significant correlation for SJ cases (r\u2009=\u20090.04, 95% CI [-0.41 to 0.47], P\u2009=\u2009.87). For the 13 SJ recipients without electroacoustic stimulation (EAS), there was a moderate, non-significant positive correlation between MA-ECochG-TR and 6-month CNC (r\u2009=\u20090.44, 95% CI [-0.14 to 0.80], P\u2009=\u2009.13). MA-ECochG-TR independently estimates performance for perimodiolar arrays. Intracochlear ECochG is less predictive for lateral wall arrays; this may be due to confounding from EAS (though this was not statistically significant) or from signal degradation with a larger electrode-modiolar distance.",

We evaluated the feasibility of a multimodal home monitoring protocol in ALS. Methods: We conducted a 3-month prospective cohort study at the University Medical Center Utrecht, Netherlands, with monthly home assessments of spirometry, accelerometry, speech, and questionnaires on functioning. The primary outcome was protocol adherence, defined as percentage of completed assessments. Secondary outcomes included acceptability ((totally) agree, neutral, (totally) disagree), and perceived burden, ranging from 0 (no burden) to 10 (extremely burdensome). Exploratory analyses were performed to evaluate changes in digital endpoints using linear mixed-effects models. Findings: Fifty patients with ALS were included (January 2023 - June 2025), of whom 47 (94%) completed the 3-month follow-up. Overall adherence was 83.2% (95% CI 76.9-88.6) and did not differ across modalities (p\u2009=\u20090.75). Adherers did not differ from non-adherers in either demographic or disease characteristics. In month 3, 93.0% to 95.3% of patients considered monthly remote assessments as acceptable, with a mean burden score of 2.0 (95% CI 1.7 to 2.3); burden was highest for speech (2.5) and the lowest for questionnaires (1.5). Digital endpoints showed significant change over 3\u2009months (all p\u2009<\u20090.05). Interpretation: This study demonstrates good adherence and acceptability of a multimodal remote monitoring protocol. Digital endpoints offer an innovative approach to capturing disease progression. Future research should assess its long-term feasibility, added value, and integration alongside established clinical outcomes.",

This randomized controlled trial (RCT) evaluated the effectiveness of Let's Play; a bespoke, caregiver-mediated early support program for Autistic children and their caregivers. This single-blind (rater) RCT included 91 parent-child dyads, randomly assigned to the Let's Play program (active support; AS [n\u2009=\u200945]) or a waitlist control (WLC; n\u2009=\u200946). Participants were caregivers of children aged 0 to 5 years with a formal diagnosis or characteristics of autism. Let's Play was delivered over 9 weeks via group workshops and in-home coaching. Primary child and caregiver outcomes, assessed at baseline, post-support, and 6-month follow-up, included parent-child engagement and parental stress, respectively. Children showed descriptive evidence of improvement in caregiver-child engagement, health-related quality of life and behaviour from baseline to post-support. Improvement in parental stress, depression and anxiety symptoms, and self-perceived parenting competence were also evident, across timepoints. However, there were no significant Group x Ttime effects for caregiver-child engagement, number of utterances or number of different words. A Group x Time effect was evident for all other child and caregiver outcome variables, underscoring the benefits of Let's Play. This research provides preliminary evidence of the effectiveness of a low-intensity, community-based, caregiver-mediated early support program for Autistic children's health-related quality of life and behavior and caregiver well-being. However, more targeted or sustained approaches to supporting caregiver-child engagement and vocal communication may be needed for improvement to be observed. The research protocol was prospectively registered on the Australian New Zealand Clinical Trials Registry (ACTRN12622001139763).",

This prospective study included 107 patients who underwent endoscopic sinus surgery for medically refractory unilateral chronic rhinosinusitis with or without nasal polyposis treated at our institution between January 2024 and March 2025. Patients with a history of previous sinus surgery or malignant disease were excluded. Detailed current and past dental histories were obtained from all patients. Preoperative paranasal sinus computed tomography and magnetic resonance imaging were evaluated for radiological signs possibly related to odontogenic pathology such as periapical lucency, mucosal thickening, or oroantral fistula as well as for anatomical variants such as dental root protrusion into the maxillary sinus. Intraoperatively, pathological specimens were obtained from all patients for histopathological examination. The data were statistically analyzed. Of the 107 patients analyzed, 25 (23%) reported a history of dental disease or intervention involving the adjacent tooth. Periapical radiolucency was identified in 67 patients (63%) and oroantral fistulas in seven patients (6%). Seventy-eight patients (73%) demonstrated radiological evidence of mucosal thickening. Among the 78 patients with radiological findings suggestive of odontogenic involvement, the most common histopathological findings were unilateral inflammatory sinonasal polyps in 41 patients (53%) and chronic inflammatory changes consistent with sinusitis in 26 patients (33%). Antrochoanal polyps were identified in four patients (5%). These findings indicate frequent coexistence of odontogenic and inflammatory sinonasal findings in unilateral disease. Exploratory comparative analysis showed no statistically significant difference in the prevalence of odontogenic findings between patients with unilateral nasal polyposis and those with non-polyp pathologies (Fisher's exact test, p\u00a0=\u00a00.829). Dental-origin pathologies and related anatomical variants appear to be encountered in patients with unilateral chronic rhinosinusitis. These findings suggest a possible association between odontogenic findings and unilateral sinus disease with or without nasal polyposis. A comprehensive dental evaluation and detailed radiological assessment should be considered as part of the preoperative workup. Furthermore, the observed coexistence of unilateral polyposis and odontogenic findings warrants further investigation to clarify the nature of this association.",

Thirty-six pediatric patients were prospectively enrolled. SWI was calculated from NREM sleep EEG at baseline, 6 months, and 12 months. Clinical and electroencephalographic (EEG) findings, including spike-wave index (SWI), seizure frequency, functional disability (PEDI), and behavioral status (CBCL) were assessed longitudinally. SWI showed a significant and sustained reduction over time following IVIg therapy (Friedman test, p\u202f<\u202f0.001), with large effect sizes at 6 and 12 months. Seizure frequency decreased and clinical scale scores improved during follow-up. However, multivariable regression analyses demonstrated no significant association between changes in SWI and changes in PEDI or CBCL scores (all p\u202f>\u202f0.05). In addition, change in seizure frequency was not an independent predictor of SWI reduction (\u03b2 = -0.007, 95% CI -0.019-0.006, p\u202f=\u202f0.274). The correlation between SWI reduction and seizure outcome was weak and non-significant (\u03c1 = -0.18, p\u202f=\u202f0.29). IVIg therapy was associated with significant and sustained electrophysiological improvement and is accompanied by clinical improvement in children with EE-SWAS and DEE-SWAS. However, changes in SWI were not significantly correlated with functional, behavioral, or seizure outcomes, suggesting a dissociation between electrophysiological and clinical responses. These findings indicate that SWI should not be considered a standalone biomarker of treatment response and should be interpreted alongside clinical parameters.",

This guideline aims to provide evidence-based recommendations for the diagnosis and management of tinnitus in Korean adults, adapted to the Korean healthcare system. A multidisciplinary panel (eight otorhinolaryngologists, one neurologist, one psychiatrist, and one audiologist) conducted systematic literature searches up to 2025 using PubMed, Embase, Cochrane Library, KoreaMed, and KMBASE. Evidence quality was assessed using the GRADE methodology. Nine key clinical questions (KQs) were developed in PICO format, and recommendations were finalized through a modified Delphi process (\u226580% agreement threshold). Imaging is recommended for the evaluation of patients with pulsatile tinnitus or asymmetric hearing loss (Grade B). Tinnitus retraining therapy (TRT) and cognitive behavioral therapy (CBT) are conditionally recommended for patients with tinnitus (Grade B). Hearing aids are conditionally recommended for patients with tinnitus and coexisting hearing loss (Grade B). Sound therapy is conditionally recommended to reduce tinnitus-related distress (Grade B). Neuromodulation (transcranial direct current stimulation (tDCS) or repetitive transcranial magnetic stimulation (rTMS)) is conditionally recommended as an adjunctive treatment (Grade B). Routine zinc and vitamin supplementation are strongly recommended against for tinnitus symptom improvement (Grade D\u2020), whereas Ginkgo biloba may be considered for patients with subjective tinnitus (Grade B). Most available evidence was predominantly of low or very low certainty. This guideline provides the first comprehensive evidence-based framework for tinnitus management in Korea. Behavioral and rehabilitative interventions provided the strongest evidence for reducing tinnitus-related distress. Considerations of Korean National Health Insurance coverage, regional accessibility, and patient preferences were integrated throughout the guideline development process. The primary therapeutic goal is to reduce tinnitus-related distress and improve functional outcomes, thereby enhancing overall quality of life.",

Dental findings are frequently the most prominent clinical features and may play a key role in identifying the condition. A 16-year-old girl presented with missing permanent teeth, impaired mastication and esthetic concerns. The patient had previously been diagnosed with growth delay despite normal endocrine evaluation, including growth hormone stimulation testing. The diagnosis of CCD was suspected during dental examination based on characteristic clinical and radiographic features. Clinical assessment revealed short stature, clavicular hypoplasia with shoulder hypermobility and typical craniofacial features. Intraoral findings included prolonged retention of primary teeth, delayed eruption of permanent dentition and Class III malocclusion. Radiographic and CBCT imaging confirmed multiple impacted and supernumerary teeth, delayed cranial suture closure and additional skeletal abnormalities consistent with CCD. A conservative, stage-based treatment approach was adopted to coordinate future surgical and orthodontic interventions according to skeletal maturity. A removable partial denture (RPD) was provided as an interim solution, resulting in improved mastication, speech and esthetics. This case emphasizes the important role of dental professionals in recognizing undiagnosed systemic conditions such as CCD. Early identification based on dental findings and appropriate timing of intervention are essential for optimizing functional and esthetic outcomes.",

This study aimed to identify language markers for specific neuropathologies using both standard clinical tests and narrative speech analysis. We analyzed data from 82 autopsy-confirmed PPA cases, including Alzheimer's disease (AD), transactive DNA-binding protein 43 (TDP-43) type C (TDP-C), Pick's disease, and 4R-tauopathies (progressive supranuclear palsy/ cortico-basal degeneration (PSP/CBD). Linear mixed-effects regression was used to analyze performance on standardized aphasia tests and narrative speech variables. TDP-C showed severe semantic deficits but high fluency, while AD was distinguished by impaired repetition. Narrative analysis differentiated 4R-Tauopathies: CBD patients demonstrated significantly poorer syntax and irregular verb inflection than PSP or Pick's, whereas PSP showed the lowest fluency. While standard tests effectively capture lexical-semantic features in AD and TDP-C, narrative measures reveal subtle grammatical and fluency differences critical for distinguishing specific tauopathies. This study outlines a more robust approach for predicting underlying pathology in PPA.",

Greater volume of the choroid plexus (ChP), a brain structure supporting neurotoxic waste clearance, is linked to neurodegeneration and cognitive decline. We tested whether poor sleep promotes neurodegeneration and cognitive deficits via ChP dysfunction. Baseline magnetic resonance imaging (MRI) -derived ChP, hippocampal, ventricular, and gray matter volumes from 635 cognitively unimpaired older adults were analyzed. Sleep was measured with the Pittsburgh Sleep Quality Index and accelerometry. Confirmatory factor analysis generated cognitive domain scores. Poorer self-reported sleep quality was associated with greater ChP volume, while accelerometry measures were not. Greater ChP volume was associated with smaller hippocampi and gray matter, and larger ventricles. ChP mediated relationships between sleep quality and hippocampal and ventricular volumes. Gray matter mediated associations between ChP and cognitive domains. Altered ChP morphology may link poor sleep to neurodegeneration and cognitive decline in older adults.",

Current methods for assessing muscle health, such as motor tasks or magnetic resonance imaging (MRI), are limited in young or severely affected individuals. This study evaluated electrical impedance myography (EIM) as a noninvasive biomarker of muscle health in PD. Sixty-four participants (11 IOPD, 27 LOPD, 26 healthy controls) were assessed. EIM phase and reactance values were obtained from bilateral limb muscles. Twenty PD participants underwent lower limb musculoskeletal MRI. Participants completed Perceived Stress Scale-10 and Patient-Reported Outcomes Measurement Information System questionnaires. Motor performance was evaluated via balance tests, 9-Hole Peg Test, grip strength, 2-Minute Walk Test, and 4-Meter Walk Test. Participants with PD reported greater impairment in pain intensity, mobility, physical stress experience, and physical function, and performed worse on motor tasks than healthy controls (all p<0.05). EIM phase at 100 and 211 kHz was reduced in participants with PD, particularly in those with IOPD and in pediatric PD participants, compared to healthy controls. Lower phase correlated with higher MRI fat fraction and poorer motor performance. With additional longitudinal investigation, EIM may represent a functionally relevant, noninvasive tool to evaluate disease severity in individuals with PD.",

The present study aims to establish the psychometric properties and validate a lexical screening tool for 19-36-month-old British English-speaking children, the WinG (Words in Game) test. Specifically, it examines gender differences in internal consistency, concurrent validity and predictive gender invariance across comprehension and production tasks. In addition, the study evaluates the diagnostic accuracy of the tool by establishing clinical cut-off scores to distinguish children with typical versus at-risk language development. Finally, it presents developmental trends in toddlers' aggregate lexical comprehension and production scores, reported in percentiles and stratified by gender. Participants were 336 English-speaking children aged 19-36 months. Sub-set of 85 children were screened with the Words in Game (WinG) test and the Preschool Language Scale (PLS-4). The PLS-4 scores were used as reference tests to ascertain psychometric properties and estimate the sensitivity and specificity of the WinG comprehension and production tasks. Girls outperformed boys on both comprehension and production tasks. The WinG comprehension and production tasks showed strong concurrent validity, with scores positively and highly correlated with the PLS-4 reference measures. Predictive gender invariance was also demonstrated, as both WinG dimensions predicted PLS-4 scores equivalently across genders. Using the 15th percentile as a cut-off, the WinG test demonstrated fair sensitivity for comprehension and good sensitivity for production, though specificity was below the desirable threshold for both tasks. The tool provides a valuable starting point for identifying early receptive and expressive lexical difficulties through direct assessment by speech and language therapists (SLTs). Clinical implications and limitations are also discussed. What is already known on this subject Lexical receptive and expressive abilities emerge and expand rapidly in the second and third years of life. Clinicians and Speech and Language therapists (SLTs) need a systematic, reliable tool to observe the early lexical skills of toddlers. What this study adds to existing knowledge This study established the psychometric properties and validated the Words in Game (WinG) test from a large sample of 19-36-month-old British English learning children to measure the receptive and expressive nouns and predicates (verbs, adjectives and adverbs). The PLS-4 scores were used as a reference standard test. The WinG comprehension and production tasks showed strong concurrent validity, with scores positively and highly correlated with the PLS-4 reference measures. The developmental trends in toddlers' lexical comprehension and production scores are reported in percentiles and stratified by gender. The diagnostic accuracy of the WinG test was ascertained, performing receiver operating curves (ROC) on comprehension and production WinG tasks, entering the 15th percentile clinical cut-off scores, as indicated by the PLS-4 reference measures. What are the clinical implications of this study? The WinG test is a valid tool designed to screen the comprehension and production of words of British English children in the second and third years of life. The WinG test is a tool to be administered by professionals with expertise in language development, such as SLTs. Thanks to its systematic, direct observation approach and validation against established measures, the WinG test demonstrates fair psychometric properties. It provides SLTs with a reliable tool for early screening of toddlers' lexical skills to identify language delays or disorders.",

We report the experience of a diagnostic day hospital that systematically integrates both a clinical pharmacist and a speech-language pathologist in a socioeconomically advantaged area. This retrospective study included patients undergoing their initial assessment at the day hospital. The primary objective was to describe their neurocognitive, pharmaceutical, and speech-language characteristics. As a secondary objective, we investigated differences according to educational level in pharmaceutical and speech-language assessments and recommendations. A total of 110 patients were included. Polypharmacy was identified in 55% of patients, and at least one pharmaceutical intervention was recommended in 75%. A high prevalence of language disorders was observed, leading to referral for speech therapy in 61% of cases. Compared with the general population consulting for neurocognitive disorders, our patients had a higher average sociocultural level. No significant differences according to educational level were observed in pharmaceutical or speech-language assessment outcomes. These findings highlight the potential value of integrating clinical pharmacy and speech-language pathology into multidisciplinary neurocognitive assessment pathways.",

However, developmental science still struggles practically and methodologically to capture, label, integrate, and understand these data streams, especially in a way that is generalizable and inclusive. This review explores the state of the art in sensing and machine learning (ML) methods to study infants 0-36 months in natural environments. It delineates (i) sensing technologies, (ii) data collection and annotation approaches, (iii) ML approaches for behaviour recognition, prediction and modelling, and (iv) translational paths towards screening and early intervention, with a focus on feasibility, inclusivity, and ethics. A systematic review of literature published between 2015 and 2025 was performed in the following databases (Scopus, Web of Science, PubMed, IEEE Xplore, ACM), in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Inclusion criteria involved studies of infants between 0 and 36 months, naturalistic or free-flowing contexts, and mobile/wearable sensing, computer vision, signal processing or ML. The review examined the sensor modalities (egocentric and exocentric camera and microphone, inertial measurement unit/actigraphy, physiological sensors), data properties (temporal resolution, density, duration), and settings (home, clinic, community). The synthesis places a primary emphasis on naturalistic motor behavior, which is the area most well-represented in the studies included. Selectively considered sensing and ML evidence for vocal and communicative behavior (including language exposure and caregiver-infant interaction), social-affective behavior, and sleep-wake regulation are presented where relevant. It also explored ML paradigms (supervised, semi- and weakly supervised, self-supervised, multimodal, sequential, and transformer-based), validation approaches, and reporting quality.",

Laboratory findings revealed elevated creatine kinase and positive serum human T-cell leukaemia virus type 1 (HTLV-1) antibody. Clinical and electrophysiological findings met revised El Escorial criteria for amyotrophic lateral sclerosis (ALS), but muscle MRI showed inflammatory changes. Muscle biopsy revealed both neurogenic and inflammatory features. While methylprednisolone showed no benefit, intravenous immunoglobulin therapy produced transient improvement in weakness with normalisation of creatine kinase levels. The patient died from respiratory failure 3 years after symptom onset. Autopsy confirmed typical ALS-TDP pathology with phosphorylated TDP-43 inclusions in motor neurons. HTLV-1 Tax-positive lymphocytes infiltrated skeletal muscles but not the central nervous system, establishing dual pathology of ALS-TDP with HTLV-1-associated myositis. The improvement most likely reflected treatment of the HTLV-1-associated myositis rather than the underlying motor neuron disease. This case highlights the importance of evaluating treatable conditions in HTLV-1-seropositive ALS patients.",

However, the prospective implications of these changes remain unclear. To examine whether perceived changes in alcohol effects 6months after MBS predict alcohol-related outcomes at 1year and whether psychological vulnerability moderates these associations. Four Belgian hospitals. Two hundred and five adults were assessed preoperatively and at 6 and 12 months postoperatively (73.5% retention). Perceived changes in alcohol effects were measured at 6 months. Alcohol use, drinking motives, and anxiety were assessed at baseline and 12 months. Three separate 2 \u00d7 2 analyses of covariance tested main and interaction effects of perceived change (increase vs. no change) and anxiety (high vs. low) on 12-month outcomes, controlling for baseline levels. Bootstrap regression models assessed robustness. At 6 months, 54.1% reported stronger and/or faster alcohol effects. Significant perceived change \u00d7 anxiety interactions were observed for alcohol use (F(1,200) = 7.33, P < .01), enhancement motives (F(1,200) = 11.95, P < .001), and coping motives (F(1,200) = 6.94, P < .01). Interaction effects for enhancement (B = 1.23, P = .02) and coping motives (B = .96, P = .04) remained significant in bootstrap analyses, whereas the interaction for alcohol use was attenuated (B = 2.76, P = .09). Perceived increases in postoperative alcohol effects were associated with stronger enhancement and coping motives, particularly among individuals with elevated anxiety. Assessing perceived alcohol sensitivity and psychological vulnerability may help identify patients at increased risk for alcohol-related problems.",

In this retrospective study, acoustic recordings from 42 patients (21 with AdLD and 21 with pMTD) at a tertiary voice center were analyzed. Participants produced six CAPE-V sentences during a standardized voice evaluation. Recordings were segmented and analyzed using an automated algorithm to compute percent creak (%), defined as creak duration relative to total voicing duration. Smoothed cepstral peak prominence (CPP) was also extracted. Hierarchical binomial logistic regression models evaluated whether creak alone or creak in combination with CPP predicted the diagnostic group. Mean creak (%) values were comparable between groups. Creak (%) did not significantly predict the\u00a0diagnostic group (P > 0.05). Inclusion of CPP did not improve model performance. Creak distributions were positively skewed in both groups, with notable interindividual variability. Creak derived from CAPE-V sentences does not differentiate AdLD from pMTD. These findings suggest that stimulus characteristics, particularly sentence length and the\u00a0associated respiratory-phonatory demands, may influence the discriminative validity of creak.

        "42415081": "ID: 42415081\nTitle: Generating Alzheimer's narratives using large language models.\nAbstract: Analyzing semi-spontaneous speech is a promising direction for supporting Alzheimer's disease (AD) assessment, yet progress is limited by the scarcity of annotated clinical data. Large Language Models (LLMs) offer new opportunities to generate synthetic narratives that may resemble speech patterns of both patients with AD and healthy controls during cognitive evaluation tasks such as the Cookie Theft Picture description. This study evaluates whether models including GPT, T5/Flan-T5, LLaMA, Mistral, and Qwen can generate clinically plausible picture-description narratives under two configurations: Human-to-Bot, where an LLM responds directly to real interviewer prompts, and Bot-to-Bot, where two LLMs simulate both interviewer and participant roles. Models were fine-tuned on transcripts from the DementiaBank Pitt Corpus and assessed using lexical and semantic metrics, as well as human expert ratings. Generated narratives were further used to augment training data for an AD vs. healthy control classifier based on BERT embeddings and an MLP architecture. LLMs differed substantially in their ability to reproduce clinically meaningful and semantically coherent narratives of patient-interviewer interactions. Mistral, LLaMA, and Qwen achieved the strongest automatic evaluation metrics, e.g., BERTScores above 0.90 in the Human-to-Bot condition-and produced narratives rated by human experts as fluent, plausible, and diagnostically informative. When combining real and synthetic narratives for classifier training, the highest F1-score reached 0.84, outperforming models trained on real data alone (F1\u2009=\u20090.74). Synthetic data generated in Human-to-Bot settings contributed most to diagnostic improvements, whereas Bot-to-Bot interactions exhibited greater variability and reduced clinical realism. LLMs can generate high-quality synthetic narratives that enhance downstream AD classification and show promising clinical plausibility in cognitive assessment contexts. Incorporating LLM-generated data provides a scalable strategy for mitigating data scarcity in dementia research. Future work should focus on improving fully synthetic dialogue quality, expanding multilingual capabilities, and refining evaluation frameworks to better capture clinically relevant linguistic features.",
        "42415806": "ID: 42415806\nTitle: A novel class-attention transformer-driven feature fusion technique-based speech disorder classification.\nAbstract: Speech disorders (SD) present significant diagnostic challenges due to the complex and indistinct acoustic characteristics embedded within speech signals. The standalone convolutional neural networks (CNNs) and vision transformers (ViT) struggle to capture SD temporal and spectral dynamics. To address these limitations, this study proposes an end-to-end binary pathological SD detection framework that processes raw audio waveforms to differentiate disordered speech from healthy speech while improving feature representation, interpretability, and generalization. A hybrid feature extraction integrating one-dimensional CNNs and ViT's self-attention mechanism is developed to extract crucial SD features. An adaptive fusion and a Class-attention transformer (CaiT)-based feature refinement is introduced to transform the extracted features into a classification-optimized global representation. Through the integration of gradient-weighted class activation mapping (Grad-CAM) and attention-based visualization with the model architecture, the temporal-localization of disorder-relevant acoustic patterns is enabled. Two benchmark datasets are utilized for model's performance evaluation, benchmarking against state-of-the-art CNNs and ViT architectures. The model is trained and internally validated on the SVD dataset using subject-level splitting, while the PD and VOICED datasets are used exclusively for external validation to assess cross-dataset generalization across neurological and heterogeneous pathological voice conditions. The proposed model achieves 97.50% accuracy on both SVD and PD datasets and 95.80% accuracy on VOICED, while maintaining a lightweight design with 5.2 million parameters. Statistical analysis further confirms the results' reliability and significance. The integration of adaptive fusion and transformer-based refinement significantly enhances SD detection performance while ensuring interpretability. The suggested framework offers a sound and proof-of-concept for diagnosing SD, allowing clinicians and speech-language pathologists to make reliable predictions and pay attention to diagnostically significant time intervals.",

Dysphagia can have serious consequences, including aspiration pneumonia and prolonged hospital stays, which need to be avoided in resource-constrained environments such as South Africa (SA). To investigate the characteristics of dysphagia in critically ill patients using an interdisciplinary assessment approach that utilises both bedside evaluations and fibreoptic endoscopic evaluation of swallowing (FEES). A retrospective file review was conducted of 68 adult patients who underwent interdisciplinary dysphagia assessments in a private SA hospital between July 2022 and January 2024. Data collected included clinical notes, anatomical and physiological markers, Penetration-Aspiration Scale (PAS) scores and post-assessment diagnoses. Descriptive statistics were employed to analyse variables such as age, gender, comorbidities and dysphagia symptoms. The mean age of participants was 59.5 years (standard deviation (SD) 17.05 years), with the majority presenting with trauma-related injuries or cerebrovascular accidents. Dysphagia was prevalent, with 49% of patients exhibiting significant swallowing difficulties. The mean PAS score was 3.44 (SD 2.82), indicating that material often entered the airway without being ejected. Notably, 17% of patients presented with silent aspiration, highlighting the need for comprehensive interdisciplinary assessment techniques. Common symptoms included pooling, dysphonia and delayed swallow triggers, which may be identified at the bedside and confirmed using FEES. Patients were referred to speech-language therapy (SLT) after a median of 13 days in the intensive care unit (ICU). Dysphagia is a significant concern in critical care, necessitating early and co-ordinated assessment strategies to minimise complications and improve patient outcomes. This study advocates enhanced protocols and interdisciplinary collaboration to manage dysphagia effectively. Early referral to SLT is critical for timely intervention, which is essential in an under-resourced setting. Future research across various settings is needed to further validate the interdisciplinary model of dysphagia assessment and management and to generate additional local data on dysphagia in the ICU. This retrospective file review demonstrates the prevalence, clinical features, and consequences of dysphagia among critically ill adults assessed with an interdisciplinary FEES approach in a South African (SA) ICU. The study contributes to important local evidence by (i) quantifying the burden of dysphagia and silent aspiration in an ICU population, (ii) showing that interdisciplinary FEES (SLP + ENT) augments the standard bedside dysphagia assessment and yields important diagnostic detail that informs safer feeding and management decisions, and (iii) identified substantial delays to SLT for assessment that likely increase the risk of complications such as aspiration pneumonia. These findings support calls for earlier SLT involvement, development of context-appropriate referral pathways and practice guidelines, and wider adoption of interdisciplinary assessment models in resource-constrained SA ICU settings.",

It is unknown if PPA symptoms in bilingual speakers differ from those of monolingual speakers. In addition, it remains unclear if one of a bilingual speaker's languages is more vulnerable to the onset of symptoms and/or is better preserved. Furthermore, bilingualism factors (e.g. order/age of language acquisition (L1/L2) and language dominance) may explain patterns of impairment both within and across the variants of PPA. To characterize the bilingualism factors, speech and language symptoms, and patterns of language impairment in a retrospective cohort of bilingual speakers with PPA. In a large cohort (N = 69) of bilingual speakers, we performed a chart review to extract information regarding self/caregiver-reported PPA symptoms, first language impacted by PPA at symptom onset, less preserved language at time of evaluation, and bilingual history factors (age/order of acquisition (L1/L2) and language dominance). We explored how emergence and presentation of symptoms associated with bilingualism factors. The presenting symptoms were mostly consistent with current PPA diagnostic criteria, although symptoms unique to bilingual speakers were reported. The language reported to first be impacted by PPA, as well as the less preserved language at the time of evaluation, was generally reported to be the less dominant language, regardless of PPA variant. These measures did not associate as closely with age/order of acquisition (L1 versus L2). Bilingual speakers with PPA may report additional symptoms that reflect their ability to speak more than one language. The less dominant language was most susceptible to the initial impact of PPA and also tended to the less preserved language at the time of evaluation. Future studies of bilingual speakers with neurodegenerative diseases should systematically consider bilingualism factors, which are likely to contribute to clinical presentation and disease progression.",

This study aimed to develop and evaluate a multilayer classification system for voice disorder diagnosis tailored for machine learning applications, and to determine its inter- and intra-rater reliability among otolaryngologists and speech-language pathologists. We conducted a diagnostic reliability study of 45 adults with voice disorders who underwent comprehensive clinical assessment, including videostroboscopy, at a tertiary voice clinic in Sydney, Australia, between February 2018 and March 2024. A multidisciplinary team developed a five-level hierarchical classification framework through iterative consensus. Four blinded raters independently applied the framework to anonymised video and clinical datasets, with 15 cases randomly repeated for intra-rater analysis. Reliability was quantified using Fleiss \u03ba statistics and intraclass correlation coefficients across all diagnostic levels. Intra-rater reliability was high (intraclass correlation coefficient range, 0.768-0.865), with comparable consistency across disciplines. Inter-rater reliability was strongest for identifying disordered vs. non-disordered voices (\u03ba = 0.812; 95% CI, 0.733-0.891) and major aetiological categories (\u03ba = 0.695; 95% CI, 0.611-0.779), supporting the utility of structured classification for foundational diagnostic decisions. Agreement declined with increasing diagnostic specificity, particularly for perceptually based conditions such as muscle tension disorders (\u03ba = 0.253; 95% CI, 0.172-0.334) and vocal fold paresis (\u03ba = 0.238; 95% CI, 0.155-0.321). Functional neurological voice disorders and structural lesions demonstrated the highest category-level agreement. These findings show that a structured, multilayer framework improves diagnostic consistency where machine learning systems most rely on stable labels and highlights key areas of diagnostic ambiguity. The system provides a practical foundation for creating reliable annotated datasets and supports future development of machine learning tools for voice disorder classification and clinical decision support.",

Recordings generate vast amounts of audio, making manual analysis impractical and requiring automated processing. Two automated algorithms have emerged: the proprietary LENA (Language ENvironment Analysis) and the open-source ACLEW (Analyzing Child Language Experiences around the World) systems; yet, systematic performance comparisons remain scarce. Here, we validate and compare the performance of these two algorithms across key measures: audio segmentation into speaker categories, conversational turn count (CTC), adult word count (AWC), and child vocalization count (CVC). This analysis is based on 25 h of manually annotated audio recordings from 50 age-matched U.S. children with diverse neurodevelopmental profiles: children with Down syndrome, Fragile X syndrome, and Angelman syndrome, children at elevated likelihood of autism, and low-risk controls. We hypothesized that the algorithms might be less accurate for children with neurodevelopmental conditions, since these children often show different patterns of volubility and vocal maturity compared to the typically developing children used to train the algorithms. Thus, we assessed the performance of algorithms across diagnostic groups, a crucial validation step for both cross-population research and the evaluation of language interventions. Results reveal that while algorithms achieve similar performance across groups, they show different patterns: LENA makes fewer segmentation mistakes but misses many segments (identification error rate = 81.3%, percent correct = 45.3%), while ACLEW shows the opposite pattern (identification error rate = 129.4%, percent correct = 69.4%). Both LENA and ACLEW achieve reasonable levels of accuracy in their automatic counts (Pearson's r ranging from 0.78 to 0.92) and maintain stable performance across diagnostic groups. We conclude with recommendations for the validation and potential use of these algorithms in research and clinical practice. SUMMARY: Our comparison of the LENA and ACLEW algorithms in analyzing children's language environment and vocal production across five neurodevelopmental profiles reveals similar performance but distinct error patterns. LENA makes fewer errors but misses speech (81.3% error rate, 45.3% correct); ACLEW makes more errors but captures more speech (129.4% error rate, 69.4% correct). Both algorithms maintain consistent performance across diagnostic groups, supporting their reliability for research with these 2-year-old populations with diverse neurodevelopmental profiles. Variations in algorithm performance are primarily driven by the total speaking time of surrounding speakers (other children and adults), rather than the diagnostic group.",

Observational, cross-sectional, and quantitative study involving 20 neurologically healthy older adults (with no signs of cognitive decline), matched by age and education, divided into two groups: one with a quadritonal average within normal limits, and the other with bilateral moderate or greater hearing loss, all users of bilateral Hearing Aids (HA). Participants were assessed through anamnesis, pure-tone audiometry, speech audiometry, tympanometry, Mini-Mental State Examination (MMSE), and MoCA-H. Comparisons between groups were conducted using Student's t-test, with a significance level of 5%. Similar performance was observed between groups in seven of the eight cognitive domains assessed by the MoCA-H. The only statistically significant difference was found in the visuo-spatial/executive domain, with lower performance in the group with hearing loss. No significant difference was found in the total MoCA-H score between the groups. Neurologically healthy older adults with and without treated hearing loss showed similar performance on the MoCA-H tasks. Only the visuospatial/executive task distinguished the groups evaluated. The MoCA-H proved to be an effective and sensitive tool in the cognitive assessment of older adults with moderate to severe hearing loss, at least in the sample studied.

This study aimed to develop a model to predict naming rehabilitation in patients with subacute PSA. Data of PSA were collected retrospectively. Logistic regression (LR) analyses by a nested fivefold cross-validation were performed to identify predictors and construct a predictive model. The efficacy of the model was evaluated using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA). Additionally, the net reclassification index (NRI) and integrated discrimination improvement (IDI) were calculated to assess the discrimination of the model. Shapley additive explanation (SHAP) values were utilized to determine the prediction role of each feature in the model. To reduce the variance of the best model, data resampling was performed using fivefold cross-validation and three distinct random seeds. A total of 199 patients and 21 clinical variables were analyzed. Lesion site, Broca's area damage, education level, Boston Diagnostic Aphasia Examination grade, and transcranial direct current stimulation (tDCS) therapy were significant in \u2265 50% of inner folds across three different random seed conditions in univariate LR analysis and were incorporated into the predictive model. The model achieved the mean area under the curve in the fivefold cross-validation, surpassing the single-predictor models (Seed 42: 0.792 \u00b1 0.099; Seed 123: 0.828 \u00b1 0.045; Seed 456: 0.816 \u00b1 0.065). The ROC curves, calibration curves, and DCA demonstrated high accuracy, consistency, and clinical utility in the prediction of rehabilitation of PSA. Furthermore, the NRI and IDI indicated that the model offered better discrimination than single-predictor models. The model showed high balanced accuracy (Seed 42: 0.892 \u00b1 0.031; Seed 123: 0.874 \u00b1 0.061; Seed 456: 0.883 \u00b1 0.074). The SHAP analysis identified the importance of these features. Notably, tDCS, as the sole modifiable core factor, holds a prominent position in the predictive model, highlighting its potential therapeutic value in accelerating language functional recovery through the facilitation of neuroplasticity. However, its therapeutic efficacy is modulated by stimulation target status (Broca's area integrity), suggesting that alternative therapeutic targets may be explored for patients with Broca's area damage. The predictive model demonstrated a strong performance and may assist clinicians in stratifying patients with aphasia for early intervention, thereby potentially improving rehabilitation outcomes. https://doi.org/10.23641/asha.32774427.",
        "42418303": "ID: 42418303\nTitle: Diagnostic Agreement and 1-Year Outcomes in Functional Neurological Disorder Following Neuroscience-Informed Assessment, Education, and Counseling: A Retrospective Cohort Study.\nAbstract: We sought to explore outcomes at 1\u00a0year in functional neurological disorder (FND) following a neuroscience-informed education and counseling assessment. Patients with FND were assessed at a quaternary neuropsychiatry clinic in Toronto, Canada, and provided education and counseling to build insight into their FND diagnosis. Patient-determined diagnostic agreement at follow-up was categorized as a binary variable: (i) symptoms attributable primarily to FND or (ii) attributable to another cause (neurological disease or unknown). One-year symptom status was patient-reported on a 7-point scale (-3 to +3), with scores \u22652 defined as meaningful improvement. Return to work/school was assessed as an indicator of global improvement of functional status. Univariate tests screened variables for inclusion in multivariate logistic regression models, which evaluated associations between diagnostic agreement and other outcomes. A total of 282 patients with FND were assessed (mean age 38.9\u00a0\u00b1\u00a012.0\u00a0years; 80.3% female), and of these, 127 had 1-year follow-up data. FND subtypes included functional movement disorder (functional weakness [26.8%], hyperkinetic movement [15.7%]), seizure (15.0%), sensory (16.5%), functional cognitive disorder (7.9%), persistent postural perceptual dizziness (14.2%), and speech/swallowing (3.9%). Diagnostic agreement was significantly associated with symptom improvement (odds ratio [OR]\u00a0=\u00a03.81, 95% CI: 1.33-11.71, p\u00a0=\u00a00.015) and global improvement (OR\u00a0=\u00a05.74, 95% CI: 1.11-37.54, p\u00a0=\u00a00.047). Psychiatric comorbidity (p\u00a0=\u00a00.026), childhood trauma (p\u00a0=\u00a00.015), and psychological triggers (p\u00a0=\u00a00.013) were associated with diagnostic agreement, while ongoing medical/neurological workup was linked to disagreement (p\u00a0<\u00a00.001). Diagnostic agreement was associated with symptom improvement and return-to-work/school status in FND patients who received a neuroscience-informed education and counseling assessment. However, given the observational design and lack of baseline measurement of diagnostic agreement, the directionality of this relationship cannot be determined.",

The convergence of machine learning (ML) with low-cost, widely available digital devices creates new opportunities for objective, scalable, and accessible PD screening and monitoring. This systematic literature review aims to examine ML approaches for PD detection, early diagnosis, severity assessment, and stage classification using four key data modalities: facial expressions, hand movements, speech and voice, and gait employing general-purpose, low-cost equipment. A systematic literature review of 133 papers published between January 2020 and June 2025 was conducted following PRISMA 2020 guidelines. Data were extracted on feature extraction techniques, assessment protocols, computational frameworks, classifier architectures, performance metrics, and participant cohorts for each modality and for multimodal fusion studies. The quality of multimodal fusion studies was evaluated using the IJMEDI checklist. Cross-modality comparison for PD vs. healthy control classification indicated a promising trend for speech and voice modality. Binary classification was the most common ML task (74.5% of studies). Support Vector Machines (SVM) and Random Forests (RF) were the predominant classifiers. While multimodal data fusion demonstrated a promising trend toward improved performance (observed in 75% of studies), this finding requires cautious interpretation due to the limited statistical validation in the source literature. This review synthesizes the current landscape of ML-based PD assessment using accessible hardware. It demonstrates the technical viability and performance advantages of multimodal systems while providing a detailed compendium of methodologies for signal processing, feature engineering, and model selection. These findings support the development of practical, cost-effective tools for remote PD screening and monitoring.",

Methods: A total of 32 individuals with ARHL who were recruited from Peking Union Medical College Hospital between September 2020 and March 2024 were enrolled, including 12 males and 20 females, aged 60-73 years (mean age: 66.1 years). Additionally, 32 age-matched individuals with normal hearing were recruited as the control group, including 14 males and 18 females, aged 60-70 years (mean age: 65.4 years). Peripheral auditory function was assessed using pure-tone audiometry (PTA). Central auditory processing was evaluated using the speech-in-noise (SIN) test and the gaps-in-noise (GIN) test. Attentional function was assessed with the digit vigilance test (DVT). Statistical analyses were performed using SPSS 27.0 software. Results: Compared with the control group, individuals with ARHL exhibited significantly prolonged DVT reaction time (RT), indicating poorer performance on the attention task [ARHL group: (210.2\u00b143.1) s; control group: (189.3\u00b137.3) s; t=2.068, P=0.043]. In the ARHL group, SIN threshold was significantly positively correlated with DVT RT (pr=0.502, P=0.005). Among all participants, both SIN and GIN thresholds were significantly positively correlated with DVT RT (SIN: pr=0.691, P<0.001; GIN: pr=0.349, P=0.006), whereas the PTA threshold showed only a marginal correlation with DVT RT (pr=0.229, P=0.075). Multiple linear regression analysis revealed that the SIN threshold was the only auditory measure independently associated with DVT RT (\u03b2=9.673, 95%CI: 3.611-15.734, P=0.002). Conclusions: Individuals with ARHL demonstrate prolonged RT on attention-related tasks, suggesting a potential decline in attentional processing speed. The association between central auditory processing ability and attentional processing speed is substantially stronger than that between peripheral auditory function and attentional processing speed. These findings suggest that central auditory processing function may have potential value in the investigation and assessment of cognitive function in older adults. \u76ee\u7684\uff1a \u63a2\u8ba8\u5e74\u9f84\u76f8\u5173\u542c\u529b\u635f\u5931\uff08age-related hearing loss\uff0cARHL\uff09\u60a3\u8005\u5916\u5468\u542c\u89c9\u529f\u80fd\u53ca\u4e2d\u67a2\u542c\u89c9\u5904\u7406\u529f\u80fd\u4e0e\u6ce8\u610f\u529f\u80fd\u4e4b\u95f4\u7684\u5173\u7cfb\uff0c\u4e3aARHL\u7684\u4e34\u5e8a\u8bc4\u4f30\u53ca\u5e72\u9884\u63d0\u4f9b\u79d1\u5b66\u4f9d\u636e\u3002 \u65b9\u6cd5\uff1a \u7814\u7a76\u5bf9\u8c61\u4e3a2020\u5e749\u6708\u81f32024\u5e743\u6708\u5c31\u8bca\u4e8e\u5317\u4eac\u534f\u548c\u533b\u9662\u768432\u4f8bARHL\u60a3\u8005\uff0c\u5176\u4e2d\u753712\u4f8b\uff0c\u597320\u4f8b\uff0c\u5e74\u9f84\u8303\u56f460~73\u5c81\uff0c\u5e73\u5747\u5e74\u9f8466.1\u5c81\u3002\u53e6\u5916\u62db\u52df32\u540d\u542c\u529b\u6b63\u5e38\u4eba\u4f5c\u4e3a\u5bf9\u7167\u7ec4\uff0c\u5176\u4e2d\u753714\u4f8b\uff0c\u597318\u4f8b\uff0c\u5e74\u9f84\u8303\u56f460~70\u5c81\uff0c\u5e73\u5747\u5e74\u9f8465.4\u5c81\u3002\u53d7\u8bd5\u8005\u5916\u5468\u542c\u89c9\u529f\u80fd\u901a\u8fc7\u7eaf\u97f3\u6d4b\u542c\u8fdb\u884c\u8bc4\u4f30\uff0c\u4e2d\u67a2\u542c\u89c9\u5904\u7406\u529f\u80fd\u901a\u8fc7\u566a\u58f0\u4e0b\u8a00\u8bed\u8bc6\u522b\uff08speech-in-noise\uff0cSIN\uff09\u53ca\u566a\u58f0\u95f4\u9694\uff08gaps-in-noise\uff0cGIN\uff09\u6d4b\u8bd5\u52a0\u4ee5\u8bc4\u4f30\u3002\u901a\u8fc7\u6570\u5b57\u8b66\u9192\u6d4b\u8bd5\uff08digit vigilance test\uff0cDVT\uff09\u8bc4\u4f30\u53d7\u8bd5\u8005\u6ce8\u610f\u529f\u80fd\u3002\u91c7\u7528SPSS 27.0\u8f6f\u4ef6\u5b8c\u6210\u7edf\u8ba1\u5206\u6790\u3002 \u7ed3\u679c\uff1a \u4e0e\u5bf9\u7167\u7ec4\u76f8\u6bd4\uff0cARHL\u60a3\u8005\u7684DVT\u53cd\u5e94\u65f6\u95f4\u663e\u8457\u5ef6\u957f\uff0c\u5dee\u5f02\u5177\u6709\u7edf\u8ba1\u5b66\u610f\u4e49\uff3bARHL\u7ec4\uff1a\uff08210.2\u00b143.1\uff09s\uff1b\u5bf9\u7167\u7ec4\uff1a\uff08189.3\u00b137.3\uff09s\uff1bt=2.068\uff0cP=0.043\uff3d\u3002SIN\u9608\u503c\u4e0eDVT\u53cd\u5e94\u65f6\u95f4\u5728ARHL\u7ec4\u4e2d\u5448\u663e\u8457\u6b63\u76f8\u5173\uff08pr=0.502\uff0cP=0.005\uff09\u3002\u5728\u6240\u6709\u53d7\u8bd5\u8005\u4e2d\uff0cSIN\u9608\u503c\u548cGIN\u9608\u503c\u5747\u4e0eDVT\u53cd\u5e94\u65f6\u95f4\u663e\u8457\u76f8\u5173\uff08SIN\uff1apr=0.691\uff0cP<0.001\uff1bGIN\uff1apr=0.349\uff0cP=0.006\uff09\uff0c\u800c\u7eaf\u97f3\u5e73\u5747\u542c\u9608\u4e0eDVT\u53cd\u5e94\u65f6\u95f4\u4ec5\u5448\u8fb9\u7f18\u76f8\u5173\uff08pr=0.229\uff0cP=0.075\uff09\u3002\u591a\u5143\u7ebf\u6027\u56de\u5f52\u5206\u6790\u7ed3\u679c\u663e\u793a\uff0cSIN\u9608\u503c\u662f\u552f\u4e00\u4e0eDVT\u53cd\u5e94\u65f6\u95f4\u72ec\u7acb\u76f8\u5173\u7684\u542c\u89c9\u8bc4\u4f30\u6307\u6807\uff08\u03b2=9.673\uff0c95%CI=3.611~15.734\uff0cP=0.002\uff09\u3002 \u7ed3\u8bba\uff1a ARHL\u60a3\u8005\u6ce8\u610f\u76f8\u5173\u4efb\u52a1\u53cd\u5e94\u65f6\u95f4\u5ef6\u957f\uff0c\u63d0\u793a\u6ce8\u610f\u52a0\u5de5\u901f\u5ea6\u53ef\u80fd\u53d7\u635f\u3002\u8001\u5e74\u4eba\u4e2d\u67a2\u542c\u89c9\u5904\u7406\u80fd\u529b\u4e0e\u6ce8\u610f\u52a0\u5de5\u901f\u5ea6\u7684\u76f8\u5173\u6027\u663e\u8457\u5f3a\u4e8e\u5916\u5468\u542c\u89c9\u80fd\u529b\u3002\u4e2d\u67a2\u542c\u89c9\u5904\u7406\u529f\u80fd\u5728\u8001\u5e74\u4eba\u8ba4\u77e5\u529f\u80fd\u7814\u7a76\u53ca\u8bc4\u4f30\u4e2d\u53ef\u80fd\u5177\u6709\u4e00\u5b9a\u7684\u6f5c\u5728\u4ef7\u503c\u3002.",

However, few technologies have met the complex requirements of health-care systems for adoption. Diabetic eye screening (DES) in England exemplifies the difficulty of understanding these requirements and translating them into real-world implementation decisions. This Review responds to a recognised policy need to develop a target product profile (TPP) for a DES AI system for use in England. The TPP outlines the requirements of the English health-care system for such a device and was developed using a modified Delphi consensus process involving interviews, surveys, and a consensus meeting. Participants included people living with diabetes, health-care professionals, health-care managers and leaders, regulators and policy makers, and developers. Thirty-five product specifications were agreed upon, covering areas such as clinical validity, utility, and environmental sustainability. Our TPP establishes clear criteria for DES AI development and deployment in England, and this TPP development process can serve as a template for initiatives to create TPPs for other AI health technologies and settings.",

Evaluation and diagnosis using valid instruments is critical for ensuring timely and appropriate intervention. This study aimed to conduct a cross-cultural adaptation and examine the psychometric properties of a Croatian adaptation of the Developmental Coordination Disorder Questionnaire (DCDQ), a 15-item parent questionnaire designed to evaluate the impact of motor coordination difficulties on performance in everyday activities. Questionnaire adaptation was conducted according to guidelines for cross-cultural adaptation of measurement instruments. The Croatian adaptation of the questionnaire was completed by parents of 413 children (5-15\u2009years). Factor structure was examined using exploratory, following by confirmatory, factor analyses. Gender and age distributions were examined using inferential statistics. Internal consistency and item-total correlations were high. Inferential statistics revealed a statistically significant difference in overall scores for sex, but not age. Factor analysis revealed a 4-factor solution different from the 3-factor solution found for the original version of the questionnaire, in which items were grouped under the following 4 factors: ball coordination, fine motor/handwriting, control during movement, and general coordination. Other tests of validity indicated that items under each factor measure unique aspects of motor coordination while at the same time being logically related to one another. Results suggest that the Croatian adaptation of the DCDQ is a potentially useful instrument for understanding and evaluating the impact of motor coordination difficulties on daily activities. Further research is necessary to more clearly determine the scale's factor structure and to confirm age cutoffs for screening purposes.",

This study aimed to investigate whether SNR improvement provided by a spatial filter can be measured during free conversation in virtual reality (VR) and to compare this SNR improvement with the benefit measured using a speech test with two spatially separated talkers in the same VR. Two experimental conditions were tested in 11 normal-hearing participants. Condition 1 involved free conversations between a participant and two confederates represented by avatars, and Condition 2 utilized an adaptive speech test with two speakers, presented by the same avatars. Acoustic simulations were used to render speech signals, background noise and room acoustics. A spatial filter with two levels of selectivity was simulated in VR using the participant's actual dynamic head orientation. Acoustic measures of the benefit of the spatial filter were derived from these simulated signals. The benefit was higher when measured in free conversations than in the speech test. Additionally, participants were found to move their heads closer to active speakers during free conversation than during the speech test. Furthermore, SNR in free conversations was closer to SNRs typical of conversational environments. These findings suggest that the effectiveness of hearing devices can be evaluated through conversations in VR at more realistic SNRs. Consequently, this approach may improve the ecological validity of hearing aid research outcomes.",

This systematic review and meta-analysis evaluated the efficacy and effectiveness of digital interventions to improve outcomes for first-time hearing aid users. The protocol was pre-registered (PROSPERO; CRD420251125785) and conducted in accordance with PRISMA 2020. PubMed, Scopus, and Web of Science were searched (January 2026). Eligible studies included randomized controlled trials, controlled clinical trials, and quasi-experimental studies evaluating internet-, app-, or web-based interventions. Outcomes were grouped into six domains: hearing aid use, benefit and satisfaction, hearing and communication, knowledge, skills and self-management, speech-in-noise performance, and psychosocial and emotional adjustment. Risk of bias was assessed using RoB 2 and ROBINS-I, and certainty of evidence using GRADE. Random-effects meta-analyses were conducted where \u22653 randomized trials reported comparable outcomes. Eleven publications (nine trials) were included. Most interventions focused on education, self-management, and counseling, with few targeting perceptual training. The most consistent improvements were observed in knowledge, skills and self-management (moderate-certainty). Evidence for hearing aid use, benefit and satisfaction, hearing and communication, and psychosocial and emotional adjustment was limited and inconsistent (low-certainty), while speech-in-noise evidence was of very low certainty. Meta-analyses of hearing aid use and IOI-HA outcomes showed no significant pooled effects. Digital interventions show the most consistent evidence for improving knowledge, skills, and self-management. Evidence for other outcomes remains limited and inconsistent. Clinicians may consider digital educational programs complementing standard care. Future research should prioritize larger, pre-registered trials with broader interventions and standardized outcomes.",

Organ preservation in cervical esophageal malignant tumors is particularly challenging because curative resection often necessitates laryngectomy. We describe a cervical esophageal carcinosarcoma that responded markedly to neoadjuvant docetaxel/cisplatin/5-fluorouracil (DCF), permitting laryngeal preservation, with a brief literature context. A woman in her 50s presented with discomfort on swallowing. Upper endoscopy identified a type-1 polypoid tumor on the posterior wall 18 cm from the incisors, with involvement near the esophageal inlet at 17 cm. Biopsies showed a spindle-cell-predominant tumor; immunohistochemistry (cytokeratin AE1/AE3, p63) demonstrated an admixed epithelial component, supporting a diagnosis of esophageal carcinosarcoma. Contrast-enhanced CT revealed an approximately 6.5-cm exophytic lesion in the cervical to upper thoracic esophagus, and PET-CT showed intense uptake (maximum standardized uptake value 15.3). Clinical staging was cT3N0M0, cStage II (UICC TNM 8th edition). Two cycles of neoadjuvant DCF induced a dramatic response, leaving only a subtle ~5-mm proximal extension toward the right posterior wall. The patient underwent robot-assisted thoracoscopic subtotal esophagectomy with 3-field lymphadenectomy, followed by gastric conduit reconstruction through the posterior mediastinal route with cervical esophagogastric anastomosis using a 23-mm powered circular stapler. Intraoperative iodine staining delineated the proximal margin, and laryngeal preservation was achieved. Pathology showed pT1b-SM1, pN0, M0, pStage I with treatment-effect grade 1a, and the proximal resection margin was negative. Histology demonstrated a continuous transition between atypical squamous cells and spindle sarcomatous elements; the sarcomatous component exhibited inflammatory infiltrates predominantly composed of lymphocytes and foamy histiocytes, with focal hyalinization, consistent with a therapeutic effect. The postoperative course was uneventful, and the patient was discharged on day 16. No adjuvant therapy was administered. At 12 months of follow-up, no evidence of recurrence or metastasis has been observed. This rare case illustrates that neoadjuvant DCF can downstage cervical esophageal carcinosarcoma and enable curative, larynx-preserving resection. Such responses support consideration of neoadjuvant chemotherapy as a strategy for functional preservation in selected patients with this histology.",
        "42422787": "ID: 42422787\nTitle: Efficacy of superiorly based nasolabial flap in post-mucor infrastructure maxillectomy defects.\nAbstract: Reconstruction of post-mucor oral cavity defects (ranging from simple alveolectomy defects to complete maxillectomy defects) will improve the function, esthetics, and general health of an individual. Various surgical and prosthetic options are available for the successful reconstruction of the defects. The nasolabial flap has versatile role in the reconstruction of oral cavity defects because of its proximity to the defect area, optimal esthetic results, and less surgical morbidity unlike distant flaps. In this study, we assessed the efficiency of the nasolabial flap in reconstruction of post-mucor infrastructure maxillectomy defects in 42 individuals by comparing the pre-surgical and post-surgical abilities to speak and swallow. Patients with post-mucor infrastructure maxillectomy defects were involved in this prospective study. Fifty-one patients who met the inclusion criteria were selected. All the study parameters (swallowing ability, hypernasality, speech intelligibility, and subjective satisfaction of an individual) were assessed preoperatively. Reconstruction of the defect was done with a superiorly based nasolabial flap. Nine patients were lost to follow up, and 42 patients were followed up for six months to evaluate the study parameters. Pre-surgical and post-surgical statistical data analysis shows that there is a significant improvement in the functional outcomes of an individual. 76% of the patients showed no signs of nasal regurgitation, dribbling of saliva, or coughing upon swallowing after reconstruction of the defect with nasolabial flap. Significant improvement in speech after the closure of maxillary defect was observed as 93% of patients had socially acceptable speech and 64.5% had normal intelligible speech postoperatively. Upon subjective satisfaction assessment, 64% of the patients were satisfied with the treatment procedure. Closure of oro-antral communication and creation of a seal between oral and nasal cavities using the nasolabial flap leads to improvement in the function of an individual in terms of speech intelligibility and swallowing ability. The nasolabial flap can be considered as an optimal option for managing post-mucor infrastructure maxillectomy defects by restoring functional and psychosocial well-being of a person.",
        "42422850": "ID: 42422850\nTitle: Improving respiratory disease detection through SSL-enhanced acoustic analysis and exercise-rest measurements.\nAbstract: Voice analysis has emerged as a promising non-invasive approach for monitoring respiratory and systemic health conditions. However, subtle physiological alterations are often difficult to capture using recordings collected at rest. In addition, combining traditional acoustic descriptors with modern self-supervised speech representations may provide complementary information for clinical voice analysis. This study evaluates a generalized screening model integrating stress-induced acoustic analysis with machine learning. We investigate how physical exertion and the fusion of traditional acoustic features with self-supervised learning embeddings (such as wav2vec 2.0 and WavLM) enhance the diagnostic sensitivity of vocal and respiratory signals. Post-Acute Sequelae of SARS-CoV-2 (PASC) is used as a case study to evaluate the proposed framework. Utilizing the DICOPERIA-Voice dataset (n = 154), we collected recordings of sustained vowel phonation (/a/) and voluntary coughing at two clinical moments: resting state and following a physiological stress protocol (six-minute walk and one-minute sit-to-stand tests). We employed a dual-feature extraction strategy, combining traditional acoustic biomarkers with high-dimensional Self-Supervised Learning (SSL) embeddings from wav2vec 2.0, WavLM and HuBERT. Binary classification (PASC vs. Healthy) was performed using Logistic Regression, evaluated via stratified 5-fold cross-validation. Physical exertion significantly improved classification performance and reduced model variability across all tasks. The fusion of acoustic features, WavLM and wav2vec 2.0 achieved peak F1-scores of 82.2% for vowel phonation and 80.8% for coughing both in post-exercise conditions. A cross-task late fusion model aggregation reached the highest overall performance, with an F1-score of 87.7%. Incorporating Self-Supervised Learning representations into acoustic analysis improves the sensitivity of voice-based screening, while post-exercise measurements further enhance the robustness and consistency of classification. Together, these strategies provide a scalable and objective framework for detecting respiratory and vocal sequelae in chronic or post-viral conditions. With further validation, this approach could be integrated into routine functional assessments, offering a rapid, non-invasive adjunct to clinical decision-making.",
        "42422859": "ID: 42422859\nTitle: xHD-Vox, an Automated Speech Model for Estimating Motor and Cognitive Scores in Huntington Disease: Development and Longitudinal Validation.\nAbstract: Huntington disease (HD) is a rare genetic neurodegenerative disease that causes progressive motor, cognitive, and psychiatric symptoms over decades after onset. Clinical care is typically provided in specialized centers with only annual clinical assessments, highlighting the need for more frequent and cost-effective monitoring. This study aimed to develop and validate xHD-Vox, a fully automated, interpretable, speech-based model for predicting the composite Unified Huntington Disease Rating Scale (cUHDRS) and its cognitive, motor, and functional components. We included 181 HD gene carriers (341 annual visits) from three French prospective cohorts: BIO-HD (NCT01412125), REPAIR-HD (NCT03119246), and MIG-HD (NCT00190450). Participants had \u226540 cytosine-adenine-guanine (CAG) repeats, available cUHDRS scores, and audio recordings of forward and backward counting (1-20). For model development and feature selection, we used a speech pathologist-annotated subset (145 visits and 90 participants). Selected speech features were then automated using Whisper, an open-source speech recognition tool. The final linear regression model, xHD-Vox, was calibrated on the training set of 269 visits (157 participants, and annotated subset included). Performance was evaluated on an independent longitudinal test set (24 participants, with 3 annual visits each) using mean absolute error, explained variance (R \u00b2), and intraclass correlation coefficient. Longitudinal decline was assessed with 2-way repeated-measures ANOVAs. Predicted 1-year and 2-year changes were compared with clinician-assessed 95% CIs. Feature selection identified four key predictors: standardized CAG-age-product score, CAG repeat length, rate of numbers pronounced per second, and the SD of that rate. On the test set, xHD-Vox achieved a mean absolute error of 2.1 for cUHDRS and explained 57% of its variance, compared with 38% when using only demographic features. Longitudinal analyses using repeated-measures ANOVAs with post hoc Tukey tests confirmed a significant decline over the 2-year follow-up for both clinician-assessed measures and xHD-Vox predictions. At the group level, the mean 1-year and 2-year changes predicted by xHD-Vox were consistent with clinically measured changes, falling within the corresponding 95% CIs. We developed xHD-Vox, an interpretable and automated model that predicts clinical scores in HD using a short speech task. Predicted scores were consistent with clinician-assessed scores, supporting its potential use in mobile apps for remote monitoring. This approach could facilitate scalable, real-time tracking of disease progression, especially in underserved regions, and enable personalized and responsive clinical care.",
        "42423253": "ID: 42423253\nTitle: Laryngeal Cryotherapy for Neurogenic Cough: Safety, Feasibility, and Prospective Outcomes.\nAbstract: Despite the prevalence of neurogenic chronic cough (NCC), treatment options remain limited. This study investigates selective laryngeal cryotherapy (SLC) as a potential sensory neurolytic therapy. The primary objective was to explore the feasibility and safety of SLC, while the secondary objectives assessed efficacy in the reduction of laryngeal hypersensation and cough symptoms. Patients with refractory NCC were prospectively recruited. Patients underwent laryngeal laser sensory testing (LST), immediately followed by awake SLC treatment. Cough measures including the cough severity index (CSI) and urge to cough visual analog scale (UTC-VAS) were collected at baseline and regular intervals. At 1-month postprocedure, additional LST was performed. Safety, tolerability, and adverse events were recorded. Thirty patients with NCC were enrolled. All patients successfully completed awake SLC. There were no serious adverse events or unanticipated adverse device effects. 21% of patients experienced at least one treatment-emergent adverse event, all of which self-resolved within 2\u2009days. Post-SLC patients had a higher mean laser power threshold, 7.5\u2009W (SD 2.42) to trigger a cough response compared to their baseline threshold of 2.8\u2009W (SD 2.76) (p\u2009<\u20090.001). By 6 months, patients demonstrated sustained improvement compared to their baseline, with a reduction in CSI of -8.25 (95% CI 11.60, -4.91) (p\u2009<\u20090.001) and UTC-VAS -18.07 (95% CI -29.71, -6.43) (p\u2009=\u20090.003). The data suggest that awake laryngeal cryotherapy is feasible, tolerable, and safe. SLC reduced laryngeal hypersensitivity, and while it is a promising treatment option for neurogenic cough, further research is required to confirm its long-term effectiveness."
