ABSTRACT
PURPOSE: This study examined spontaneous, spoken-to-a-model, and two sung modes in speakers with Parkinson's disease (PD), speakers with cerebellar disease (CD), and healthy controls. Vocal performance was measured by intelligibility scores and listeners' perceptual ratings. METHOD: Participants included speakers with hypokinetic dysarthria secondary to PD, those with ataxic dysarthria secondary to CD, and healthy speakers. Participants produced utterances in four vocal modes: spontaneous speech, spoken-to-a-model, sung-to-a-model, and spontaneous singing. For spoken-to-a-model and sung-to-a-model modes, written material was provided the model. For spontaneous singing, participants sang songs that they endorsed as familiar. DEPENDENT VARIABLES: In Experiment I, listeners orthographically transcribed the audio samples of the first three vocal modes. In Experiment IIa, raters evaluated the accuracy of the pitch and rhythm of the spontaneous singing of familiar songs. Finally, familiar songs and sung-to-a-model utterances were rated on a competency scale by a second group of raters (Experiment IIb). RESULTS: Results showed increases in intelligibility during the spoken-to-a-model mode compared with the spontaneous mode in both PD and CD groups. Singing enhanced the vocal output of speakers with PD more than in speakers with CD, as measured by percent intelligibility. PD participants' pitch and rhythm accuracy and competency in singing familiar songs was rated more favorably than those produced by CD participants. CONCLUSIONS: The findings reveal a vocal task effect for spoken utterances in both groups. Sung exemplars, more impaired in CD, suggest a significant involvement of the cerebellum in singing.

INTRODUCTION: Myasthenia Gravis (MG) is an autoimmune disease. The characteristic symptoms of the disease are muscle weakness and fatigue. These symptoms affect de oral muscles causing dysarthria, affecting about 60% of patients with disease progression. PURPOSE: Describe the speech pattern of patients with MG and comparing with healthy controls (HC). MATERIAL AND METHODS: Case-control study. Participants were divided in MG group (MGG) with 38 patients MG diagnosed and HC with 18 individuals matched for age and sex. MGG was evaluated with clinical and motor scales and answered self-perceived questionnaires. Speech assessment of both groups included: recording of speech tasks, acoustic and auditory-perceptual analysis. RESULTS: In the MGG, 68.24% of the patients were female, with average age of 50.21 years old (±16.47), 14.18 years (±9.52) of disease duration and a motor scale of 11.19 points (±8.79). The auditory-perceptual analysis verified that 47.36% (n = 18) participants in MGG presented mild dysarthria, 10.52% (n = 4) moderate dysarthria, with a high percentage of alterations in phonation (95.2%) and breathing (52.63%). The acoustic analysis verified a change in phonation, with significantly higher shimmer values in the MGG compared to the HC and articulation with a significant difference between the groups for the first formant of the /iu/ (p = <.001). No correlation was found between the diagnosis of speech disorder and the dysarthria self-perception questionnaire. CONCLUSION: We found dysarthria mild in MG patients with changes in the motor bases phonation and breathing, with no correlation with severity and disease duration.

INTRODUCTION: Pseudobulbar palsy (PBP) is characterized by supranuclear lesions in the corticobulbar pathway. Neoplasia, inflammatory, demyelinating, and stroke are possible etiologies of this disorder. CASE REPORT: We report an elderly female who presented with dysarthria. She was dysarthric with a hypernasal voice, no apraxia or aphasia was observed. Tongue movements were slow with limited amplitude. Her soft palate dropped bilaterally; gag reflex was present. Also, she reported swallowing difficulty and choking with her saliva. Bilateral vertical and horizontal gaze were intact to either voluntary or oculocephalic movements. A cranial CT scan was suggestive of artery of Percheron (AOP) infarction. Brain magnetic resonance imaging showed hypersignal on diffusion-weighted and T2-weighted images and hyposignal on apparent diffusion coefficient in both thalami. CT angiography scan revealed an AOP originating from the left posterior cerebral artery. The swallowing study with a videofluoroscopic demonstrated oral and pharyngeal phases with severe dysfunction. CONCLUSION: To the authors' knowledge, there are two cases of individuals with artery of Percheron infarction who developed PBP associated with other clinical syndromes. Still, isolated PBP following infarction of Percheron's artery was not reported. We hypothesized that the PBP may have occurred because of the existence of vascular territory variations in the perforating arteries that arise from the AOP.

BACKGROUND: Dysarthric symptoms in Parkinson's disease (PD) vary greatly across cohorts. Abundant research suggests that such heterogeneity could reflect subject-level and task-related cognitive factors. However, the interplay of these variables during motor speech remains underexplored, let alone by administering validated materials to carefully matched samples with varying cognitive profiles and combining automated tools with machine learning methods. OBJECTIVE: We aimed to identify which speech dimensions best identify patients with PD in cognitively heterogeneous, cognitively preserved, and cognitively impaired groups through tasks with low (reading) and high (retelling) processing demands. METHODS: We used support vector machines to analyze prosodic, articulatory, and phonemic identifiability features. Patient groups were compared with healthy control subjects and against each other in both tasks, using each measure separately and in combination. RESULTS: Relative to control subjects, patients in cognitively heterogeneous and cognitively preserved groups were best discriminated by combined dysarthric signs during reading (accuracy = 84% and 80.2%). Conversely, patients with cognitive impairment were maximally discriminated from control subjects when considering phonemic identifiability during retelling (accuracy = 86.9%). This same pattern maximally distinguished between cognitively spared and impaired patients (accuracy = 72.1%). Also, cognitive (executive) symptom severity was predicted by prosody in cognitively preserved patients and by phonemic identifiability in cognitively heterogeneous and impaired groups. No measure predicted overall motor dysfunction in any group. CONCLUSIONS: Predominant dysarthric symptoms appear to be best captured through undemanding tasks in cognitively heterogeneous and preserved cohorts and through cognitively loaded tasks in patients with cognitive impairment. Further applications of this framework could enhance dysarthria assessments in PD. © 2021 International Parkinson and Movement Disorder Society.

PURPOSE: To evaluate speech intelligibility and dysarthria, correlated to the functional assessment of Amyotrophic Lateral Sclerosis (ALS). METHODS: Quantitative-descriptive study approved by REC under No. CAAE 62912416.4.0000.5404, comprised of 19 individuals with sporadic or familiar ALS. Data were collected using the Dysarthria Protocol and the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-Re). We used visual analogue scale (VAS) to assess speech intelligibility and summary measures; and Spearman's coefficients of correlation for the instruments with significance level of 5%. RESULTS: Speech intelligibility is compromised (41.37±39.73) in varied degrees with positive correlation with the general degree of dysarthria (p=<.0001), and with all the analyzed speech parameters, indicating impact on the speech deterioration of the studied group. There is negative correlation between speech intelligibility and the results of the bulbar sections - speech and deglutition (p=0.0166), arm - activities with the upper limb (p=0.0064) and leg - activities with the lower limb (p=0.0391). Breathing (p=0.0178), phonation (p=0.0334) and resonance (p=0.0053) parameters showed a negative correlation with the item "speech" of the ALSFRS-Re. CONCLUSION: Results show impaired speech intelligibility and dysarthria, and evidence breathing, phonation and resonance as important markers of the disease progression. A thorough and early evaluation of the oral motor production allows for a better management of alterations in ALS.
OBJETIVO: Avaliar a inteligibilidade de fala e disartria, correlacionando com a avaliação funcional da ELA. MÉTODO: Estudo quantitativo-descritivo aprovado pelo CEP, sob nº CAAE 62912416.4.0000.5404, constituído por 19 pessoas com ELA, esporádica ou familiar. Para coleta, aplicou-se o Protocolo de Disartria e Escala de Avaliação Funcional da Esclerose Lateral Amiotrófica (ALSFRS-Re). Para análise, foi utilizada escala visual analógica para inteligibilidade de fala e medidas de resumo e correlação dos instrumentos pelo Coeficiente de Spearman com nível de significância de 5%. RESULTADOS: A inteligibilidade de fala está comprometida (41,37±39,73) em graus variados com correlação positiva com o grau geral de disartria (p=<,0001) e com todos os parâmetros de fala analisados, indicando impacto na deterioração da fala do grupo estudado. Há correlação negativa entre inteligibilidade de fala e resultados das seções bulbar fala e deglutição (p=0,0166), braço atividades com membro superior (p=0,0064) e perna atividades com membro inferior (p=0,0391). Os parâmetros de respiração (p=0,0178), fonação (p=0,0334) e ressonância (p=0,0053) apresentaram correlação negativa com o item "fala" do ALSFRS-Re. CONCLUSÃO: Os achados mostram prejuízo da inteligibilidade de fala e disartria e evidenciam respiração, fonação e ressonância como importantes marcadores da progressão da doença. Uma avaliação criteriosa e precoce da produção motora oral permite melhor gerenciamento das alterações na ELA.

A encefalite límbica vem sendo descrita como um distúrbio neurológico raro, que afeta seletivamente as estruturas do sistema límbico. Clinicamente, é caracterizada como uma desordem neurológica debilitante, que se desenvolve como encefalopatia rapidamente progressiva, causada por inflamação encefálica. Objetivamos aqui relatar um caso de encefalite do sistema límbico de provável etiologia autoimune para melhor conhecimento da comunidade médica, bem como averiguar métodos diagnósticos deste quadro. Paciente do sexo masculino, 59 anos, admitido em nosso serviço com queixa de confusão mental. O exame clínico evidenciou desorientação, disartria, paresia e parestesia no hemicorpo esquerdo, dificuldade de marcha, desvio de rima e histórico de epilepsia há 2 anos. No estudo por ressonância magnética do crânio, foram observadas extensas lesões que acometiam a região mesial do lobo temporal direito, todo o hipocampo e giro para-hipocampal direito, estendendo-se pelo fórnix até a porção posterior do hipocampo esquerdo, substância branca do lobo frontal bilateral. Mediante os resultados da investigação complementar, o paciente foi tratado com pulsoterapia de metilpredinisolona por 5 dias, resultando na regressão parcial dos sintomas. Atualmente, o paciente se encontra em seguimento ambulatorial para acompanhamento. A encefalite límbica é uma doença rara, porém muito importante de ser investigada e diagnosticada precocemente, uma vez que a progressão da doença pode causar incapacidade e sequelas irreversíveis.
Limbic encephalitis has been described as a rare neurological disorder affecting the limbic system structures selectively. Clinically, it is characterized as a debilitating neurological syndrome that develops as a quickly progressive encephalopathy caused by brain inflammation. This paper reports a case of limbic encephalitis, probably of autoimmune etiology, aiming to improve the knowledge of the medical community, and to promote a debate on diagnosis methods for this pathology. The patient is male, 59 years old, and was admitted at our service complaining of mental confusion. The clinical examination showed disorientation, dysarthria, left hemiparesis and paresthesia, gait difficulties, light asymmetrical smile, and history of epilepsy 2 years ago. The magnetic resonance imaging of skull showed extensive lesions affecting the mesial region of the right temporal lobe, the entire hippocampus, and right parahippocampal gyrus, extending through the fornix to the posterior portion of the left hippocampus, white matter of bilateral frontal lobe. Based on the complementary investigation results, the patient was treated with intravenous methylprednisolone for five days. Currently, he is being followed in the outpatient's department. Although being rare, limbic encephalitis shall be investigated and diagnosed early because its progression can lead to disability and irreversible sequelae

PURPOSE: Investigate the association between levodopa therapy and vocal characteristics in Parkinson's disease patients. SEARCH STRATEGY: Studies published at MEDLINE, LILACS, and SciELO, from 1960 to December 2016. A systematic review and meta-analysis was performed using the following keywords: Parkinson's disease; levodopa; L-dopa; voice; speech disorders; dysphonia; dysarthria. After analyzing titles and abstracts, two independent reviewers selected all clinical trials that met the eligibility criteria and selected the articles and the data recorded in a previously standardized table. SELECTION CRITERIA: Trials published in English between 1960 and December 2016 individuals with clinical diagnosis of Parkinson's disease; use of levodopa therapy in stable doses; acoustic analysis combined or not with auditory-perceptual analysis to evaluate the vocal parameters under investigation. DATA ANALYSIS: The following vocal parameters were analyzed: fundamental frequency (F 0), jitter, and vocal intensity. Standardized mean differences (SMD) were calculated using the Comprehensive Meta-analysis V2 software. RESULTS: Nine articles met the eligibility criteria and were selected, with a total of 119 individuals. From these, six articles with 83 individuals were included in the meta-analysis. During the levodopa therapy "on" state, modifications in F 0 (SMD=0.39; 95% CI - 0.21-0.57) and jitter (SMD=0.23; 95% CI - 0.02-0.45) were observed. Vocal intensity was not affected (SMD=0.09; 95% CI - 0.22-0.39) by levodopa ingestion. Data of the included studies were controversial in the auditory-perceptual analysis of voice. CONCLUSION: Levodopa therapy modifies F0 and jitter. No changes in vocal intensity were observed in either the "on" or "off" states of levodopa therapy.

Introduction: Dysarthria is a speech disorder most frequently associated with cerebral palsy (CP). The approach from the phono-audiology perspective is typically based on clinical observation criteria for assessment, diagnosis and intervention. Objective: Identify existing speech-language therapies for the treatment of dysarthria in children with cerebral palsy and assess their effectiveness according to the International Classification of Functioning, Disability and Health (ICF). Materials and Methods: Systematic review carried out according to Cochrane recommendations. Randomized and quasi-experimental clinical studies with children with CP and dysarthria were considered. The search was carried out through the on-line platforms CINAHL Plus, Central (Cochrane), Embase, SciELO and LILACS, Medline (Pub Med), Speech Bite and ScienceDirect. Identified studies were reviewed independently by two authors; disagreements were resolved by a third party. Risk of bias was assessed using Cochrane's risk of bias assessment tool. Results: 840 studies were identified in the on-line search. Only three studies met the inclusion criteria. These correspond to quasi-experimental studies and all three indicate that an intervention model focused on basic motor processes related to respiration, phonation, articulation, fluency and prosody, does improve voice and speech functions. Conclusions: There is no evidence to conclude that there is an effective treatment for dysarthria in children with CP.

BACKGROUND The body of literature on oral motor and swallowing disorders in patients with ataxia telangiectasia (AT) is limited. CASE REPORT The purpose of this study was to characterize oral motor and swallowing disorders in two siblings with AT, based on oral motor and swallowing assessments. Specific procedures were applied for oral motor and swallowing assessments and both patients underwent videofluoroscopy (VFS). Case 1 presented vocal instability, change in postural control during feeding; food retention in oral cavity; slower oral transit time; and multiple swallowing (signs for solid and liquid). Case 2 presented parted lips at rest and reduced muscle strength; reduced strength and mobility of the tongue; vocal weakness and instability; reduced speech precision and intelligibility; decreased intonation pattern; food retention in oral cavity during feeding; slower oral transit time; multiple swallowing (signs for solid and liquid); poor bolus ejection; incoordination and difficulty in controlling the sips of water taken from the cup; altered cervical auscultation after swallowing and respiratory distress (liquid and puree). For both patients VFS results revealed laryngeal penetration for liquid. CONCLUSIONS Although the literature describes the occurrence of dysarthria and swallowing disorders in patients with AT, little attention has been given to describing which oral motor deficits are responsible for these disorders. Early identification of swallowing alterations and rehabilitation could decrease the risk of aspiration pneumonia. Future studies are necessary in order to investigate the deterioration process of swallowing in AT and the influence of rehabilitation in maintaining functional health.

Phonoarticulation is characterized by changes in resonance, diadochokinesis, prosody, sound frequency, vocal quality, and intraoral pressure. The main aim of this study was to characterize the phonoarticulation in spinocerebellar ataxia type 3 (SCA3) and correlate it with clinical and genetic factors. Thirty-one patients with SCA3 who were subjected to spontaneous speech recordings and phonoarticulatory diadochokinesis (DDK) participated in the study. Speech analyses were performed starting after 10 s of spontaneous speech, by three experienced speech therapists, using a protocol for dysarthria adapted from the Mayo Clinic. The intra-evaluator reliability was analyzed. The lower the patient's age at disease onset was, the more frequent the occurrences of monofrequency and altered speech rhythm were. Articulation, DDK, resonance, and prosody showed a moderate correlation with the number of "CAG" triplet repeats. We conclude that the phonoarticulation of patients with Machado-Joseph disease (MJD) is characterized by mixed dysarthrophonia with cerebellar and hypokinetic components, and that there is a tendency toward higher frequency of dysarthrophonia symptoms with lower age of disease onset, longer time since onset and higher number of "CAG" triplet repeats.
