BACKGROUND: The detection and characterization of speech changes may help in the identification of neurodegenerative diseases and have the potential to help with patient characterization and monitoring. Yet, there is limited research validating the presence of speech changes across different types of neurodegenerative disease. We report on the relationships between speech and other clinical assessments in the individuals with different dementia diagnoses and in comparison to healthy older adults.
METHODS: We analyzed speech recordings from 109 patients (52F, 57M; Age = 72.63± 8.61) who were diagnosed with various neurodegenerative diseases, including Alzheimer\'s disease, Frontotemporal Dementia, and Vascular Cognitive Impairment, in a cognitive neurology memory clinic. Speech recordings of an open-ended picture description task were processed using the Winterlight speech analysis platform which generates >500 acoustic and linguistic features. We investigated the linear relationship between the speech features and clinical assessments including the Mini Mental State Examination (MMSE), Western Aphasia Battery (WAB), and Mattis Dementia Rating Scale while controlling for age, sex and years of education. Speech features that were significantly associated with clinical measures were then included in group comparisons with healthy older adults (N = 74, ∼39F; Age = 61.31±7.29).
RESULTS: Speech features including lexical and syntactic features were significantly correlated with clinical assessments in patients, across diagnoses. Lower MMSE scores were associated with the use of more familiar nouns (β = -1.60, p<.001). Similarly, increased impairment as assessed by the WAB was correlated with the use of higher frequency nouns (β = -0.01, p<.001). Patients used significantly more nouns (z = 6.25, p<.001) and shorter words (z = 8.33, p<.001) than the healthy older adults. Their speech duration was also significantly shorter (z = 7.98, p<.001) and they paused more (z = 5.19, p<.001).
CONCLUSIONS: Speech changes representing decreased speech, with simpler vocabularies and syntax, were detectable in patients with different neurodegenerative diseases and correlated with clinical outcomes. These same speech patterns differed in patients with neurodegenerative disease compared to healthy older adults. Speech has the potential to be a sensitive measure for detecting cognitive impairments across various neurodegenerative diseases.

This study aims to demonstrate the feasibility of using a new wireless electroencephalography (EEG)-electromyography (EMG) wearable approach to generate characteristic EEG-EMG mixed patterns with mouth movements in order to detect distinct movement patterns for severe speech impairments. This paper describes a method for detecting mouth movement based on a new signal processing technology suitable for sensor integration and machine learning applications. This paper examines the relationship between the mouth motion and the brainwave in an effort to develop nonverbal interfacing for people who have lost the ability to communicate, such as people with paralysis. A set of experiments were conducted to assess the efficacy of the proposed method for feature selection. It was determined that the classification of mouth movements was meaningful. EEG-EMG signals were also collected during silent mouthing of phonemes. A few-shot neural network was trained to classify the phonemes from the EEG-EMG signals, yielding classification accuracy of 95%. This technique in data collection and processing bioelectrical signals for phoneme recognition proves a promising avenue for future communication aids.

OBJECTIVE: The present investigation examined how factors such as cleft type, age of primary palatal surgery, diagnosed syndromes, hearing problems, and malocclusions could predict persistent speech difficulties and the need for speech services in school-aged children with cleft palate.
METHODS: Participants included 100 school-aged children with cleft palate. Americleft speech protocol was used to assess the perceptual aspects of speech production. The logistic regression was performed to evaluate the impact of independent variables (IV) on the dependent variables (DV): intelligibility, posterior oral CSCs, audible nasal emission, hypernasality, anterior oral CSCs, and speech therapy required.
RESULTS: Sixty-five percent of the children were enrolled in (or had received) speech therapy. The logistic regression model shows a good fit to the data for the need for speech therapy (Hosmer and Lemeshow\'s χ2(8)=9.647,p=.291). No IVs were found to have a significant impact on the need for speech therapy. A diagnosed syndrome was associated with poorer intelligibility (Pulkstenis-Robinson\'s χ2(11)=7.120,p=.789). Children with diagnosed syndromes have about six times the odds of a higher hypernasality rating (Odds Ratio = 5.703) than others. The cleft type was significantly associated with audible nasal emission (Fisher\'sexactp=.006). At the same time, malocclusion had a significant association with anterior oral CSCs (Fisher\'sexactp=.005).
CONCLUSIONS: According to the latest data in the Cleft Registry and Audit Network Annual Report for the UK, the majority of children with cleft palate attain typical speech by age five. However, it is crucial to delve into the factors that may influence the continuation of speech disorders beyond this age. This understanding is vital for formulating intervention strategies aimed at mitigating the long-term effects of speech disorders as individuals grow older.

The S3 Guideline on the Treatment of Language Development Disorders: Summary of Recommendations Abstract: The German S3 Guidelines on the Treatment of Developmental Speech and Language Disorders (AWMF: No. 049-015) were published on the AWMF homepage at the end of 2022. The German Society for Phoniatrics and Paedaudiologie coordinated the work and developed the guideline text together with linguists and speech and language therapists. Many scientific medical societies consented to the respective recommendations. For the first time in the German-speaking area, the guideline group reviewed international research results on the treatment of various speech and language disorders and formulated evidence- or consensus-based recommendations for clinical care. The present article summarizes these recommendations and evaluates the guidelines from the perspective of child and adolescent psychiatry and psychotherapy.
Zusammenfassung: Die S3-Leitlinie zur Therapie von Sprachentwicklungsstörungen (AWMF: Nr. 049-015), die Ende 2022 auf der Homepage der AWMF veröffentlich wurde, ist unter Federführung der Deutschen Gesellschaft für Phoniatrie und Pädaudiologie in Kooperation mit zahlreichen Sprachwissenschaftler_innen und Sprachtherapeut_innen entwickelt und von zahlreichen wissenschaftlichen medizinischen Fachgesellschaften konsentiert worden. Die Leitliniengruppe hat erstmalig für den deutschen Sprachraum versucht, die internationale Studienlage zur Therapie unterschiedlicher Sprach- und Sprechstörungen aufzuarbeiten und darauf basierend Evidenz- oder auch Konsensus-basierte Empfehlungen für die klinische Versorgung zu formulieren. In dem vorliegenden Artikel werden diese Empfehlungen zusammenfassend dargestellt, und es wird eine Wertung der Leitlinie aus Kinder- und Jugendpsychiatrischer Sicht vorgenommen.

Laryngeal dystonia is a potentially disabling task specific dystonia primarily affecting speech. The evaluation and diagnosis of laryngeal dystonia remain challenging, and often require a multi-disciplinary approach, involving collaboration among speech language pathologists, neurologists and laryngologists (1-5). It is crucial to correctly differentiate between the types of laryngeal dystonia due to the distinct therapeutic approaches and responses to botulinum toxin therapy or speech therapy. For educational purposes, we have divided laryngeal dystonia into two main types: adductor and abductor dystonia. In this article, we describe a series of examination techniques that can assist movement disorders neurologists diagnosing this condition, and appropriately differentiating the most common forms of laryngeal dystonia.

The process of identification and management of neurological disorder conditions faces challenges, prompting the investigation of novel methods in order to improve diagnostic accuracy. In this study, we conducted a systematic literature review to identify the significance of genetics- and molecular-pathway-based machine learning (ML) models in treating neurological disorder conditions. According to the study\'s objectives, search strategies were developed to extract the research studies using digital libraries. We followed rigorous study selection criteria. A total of 24 studies met the inclusion criteria and were included in the review. We classified the studies based on neurological disorders. The included studies highlighted multiple methodologies and exceptional results in treating neurological disorders. The study findings underscore the potential of the existing models, presenting personalized interventions based on the individual\'s conditions. The findings offer better-performing approaches that handle genetics and molecular data to generate effective outcomes. Moreover, we discuss the future research directions and challenges, emphasizing the demand for generalizing existing models in real-world clinical settings. This study contributes to advancing knowledge in the field of diagnosis and management of neurological disorders.

BACKGROUND: Emerging research shows that children and young adults (CYAs) with cerebral palsy (CP) are at higher risk for attention-deficit/hyperactivity disorder (ADHD). However, little is known about the clinical and functional characteristics of CYAs with these co-occurring disorders.
OBJECTIVE: To estimate associations between a diagnosis of ADHD among CYAs with CP and clinical and functional characteristics.
METHODS: This retrospective, cross-sectional study used data from the electronic health records of CYAs (aged 4-26 years) with CP (n = 1145). We used bivariate and multivariable analyses to estimate associations between an ADHD diagnosis, CP type, Gross Motor Function Classification System (GMFCS) level, speech or language disorder, and intellectual disability.
RESULTS: 18.1 % of CYAs with CP had a diagnosis of ADHD. CYAs with spastic-bilateral CP had lower odds of ADHD (adjusted odds ratio [AOR] = 0.58; 95 % confidence interval [CI], 0.35-0.96). Odds of having ADHD were significantly lower for those with GMFCS levels III-V (AOR = 0.10; 95 % CI, 0.06-0.15).
CONCLUSIONS: Our study found that a diagnosis of ADHD among CYAs with CP was associated with greater clinical and functional impairments compared to counterparts without ADHD. Findings highlight the need to screen for both conditions because of the high comorbidity rates in this population.

OBJECTIVE: To develop a universal system for assessing the speech function in patients with congenital palatal cleft in the postoperative period.
METHODS: A universal system for assessing the speech function for patients with a palatal cleft can be applied both after the primary operation of uranoplasty and for patients diagnosed with velopharyngeal insufficiency (VPI). The patient\'s speech is assessed according to the following criteria: defects in the pronunciation of consonants by place of articulation: labial, labiodental, lingual-dental, lingual-palatal, lingual-alveolar; speech breathing; tongue position; directed air stream; voicing disorders; The patient\'s is also evaluated for the following findings: hypernasality (reflected speech); hypernasality (spontaneous speech); hyponasality; pharyngeal reflex; audible nasal emission/turbulence; facial grimaces; speech intelligibility. The speech therapy and dental assessments are added to obtain a value characterizing the patient\'s condition: from 0 to 10 scoring indicates than only speech therapy correction is needed; from 11 to 18 - the decision on the necessity of surgical treatment is made by the surgeon together with the speech therapist, from 18 to 25 - surgical treatment is necessary with subsequent sessions with a speech therapist.
RESULTS: With the help of this questionnaire, the operating surgeon can more accurately and objectively assess in dynamics the result of the surgical treatment, regardless of the results of speech therapy treatment in the postoperative period. The creation of this scoring system for speech assessment is aimed at objectivizing the results of uranoplasty and speech-improving operations. It allows the surgeon to compare the effectiveness of different surgical methods.
CONCLUSIONS: The universal scoring system for assessing the state of speech function can be applied in the diagnosis of a patient with a palatal cleft both after the primary operation on the palate and after corrective surgical interventions. It allows monitoring progress and identifying dynamics in surgical and speech therapy treatment.
UNASSIGNED: Разработать универсальную систему оценки речевой функции у пациентов с врожденной расщелиной неба в послеоперационном периоде.
UNASSIGNED: Была разработана универсальная система оценки речевой функции для пациентов с расщелиной неба, которая может быть применена как после первичной операции уранопластики, так и для пациентов с диагнозом небно-глоточная недостаточность (НГН). Речь пациента оценивают по следующим критериям: дефекты произношения согласных по месту артикуляции: губные, губно-зубные, язычно-зубные, язычно-небные, язычно-альвеолярные; речевое дыхание; положение языка; направленная воздушная струя; нарушение озвончения. Стоматологическая оценка включает следующие критерии: гиперназальность (отраженная речь); гиперназальность (спонтанная речь); гипоназальность; глоточный рефлекс; слышимая носовая эмиссия/турбулентность; лицевые гримасы; разборчивость речи. Логопедическую и стоматологическую оценки складывают и получают значение, характеризующее состояние пациента. При значении от 0 до 10 показана только логопедическая коррекция; от 11 до 18 — решение о необходимости хирургического лечения принимается хирургом совместно с логопедом, от 18 до 25 — необходимо хирургическое лечение с последующими занятиями с логопедом.
UNASSIGNED: При помощи данной анкеты оперирующий хирург может более точно и объективно оценить в динамике результат оперативного лечения. Создание данной балльной системы оценки речи направлено на объективизацию результатов операции уранопластики и речеулучшающих операций, а также дает хирургу возможность сравнивать эффективность различных хирургических методик.
UNASSIGNED: Универсальная балльная система оценки состояния речевой функции может быть применена в диагностике пациента с расщелиной неба как после первичной операции на небе, так и после корригирующих оперативных вмешательств. Она позволяет отследить прогресс и выявить динамику в хирургическом и логопедическом лечении.

BACKGROUND: Patients with classic-onset corticobasal syndrome (CBS) present with asymmetric limb apraxia and parkinsonism. We have, however, observed patients who initially present with speech and/or language (SL) problems and several years later develop CBS (i.e., SL-onset CBS). We aimed to compare clinical, neuroimaging and pathological characteristics of classic-onset CBS with SL-onset CBS.
METHODS: We conducted a retrospective cohort study of 62 patients who met criteria for CBS (17 presented with classic-onset CBS and 45 had SL-onset CBS). We compared demographics, clinical characteristics, and grey and white matter volume loss with SPM12 between groups and assessed pathology and corticobasal degeneration (CBD) pathological lesion counts in patients who had died and undergone autopsy.
RESULTS: Median age at CBS diagnosis was 66.4 years in classic-onset CBS and 73.6 years in SL-onset CBS. Classic-onset CBS had higher frequencies of dystonia, myoclonus, and alien limb phenomenon, while SL-onset CBS had a higher frequency of vertical supranuclear gaze palsy. Both groups showed smaller frontoparietal volumes than controls, with SL-onset CBS having greater volume loss in the left supplementary motor area than classic-onset CBS. All three classic-onset CBS cases with autopsy (100 %) had CBD pathology while 8/21 of SL-onset CBS cases (38 %) had CBD. Pathological lesion burden (including astrocytic plaques) did not differ between classic-onset and SL-onset CBS.
CONCLUSIONS: Classic-onset and SL-onset CBS appear to be different syndromes, with the former being a more profuse motor syndrome. The more widespread volume loss in SL-onset CBS likely reflects longer disease course.
