Abstract
Deep brain stimulation (DBS) is an effective surgical therapy for carefully selected patients with medication refractory essential tremor (ET). The most popular anatomical targets for ET DBS are the ventral intermedius nucleus (VIM) of the thalamus, the caudal zona incerta (cZI) and the posterior subthalamic area (PSA). Despite extensive knowledge in DBS programming for tremor suppression, it is not uncommon to experience stimulation induced side effects related to DBS therapy. Dysarthria, dysphagia, ataxia, and gait impairment are common stimulation induced side effects from modulation of brain tissue that surround the target of interest. In this review, we explore current evidence about the etiology of stimulation induced side effects in ET DBS and provide several evidence-based strategies to troubleshoot, reprogram and retain tremor suppression.

Abstract
PURPOSE As Huntington disease (HD) progresses, speech and swallowing difficulties become more profound. These difficulties have an adverse effect on health-related quality of life (HRQOL), thus psychometrically robust measures of speech and swallowing are needed to better understand the impact of these domains across the course of the disease. Therefore, the purpose of this study is to establish the clinical utility of two new patient-reported outcome measures (PROs), HDQLIFE Speech Difficulties and HDQLIFE Swallowing Difficulties. METHODS Thirty-one participants with premanifest or manifest HD, and 31 age- and sex-matched healthy control participants were recruited for this study. Participants completed several PROs [HDQLIFE Speech Difficulties, HDQLIFE Swallowing Difficulties, Communication Participation Item Bank (CPIB)], as well as several clinician-rated assessments of speech and functioning. A computational algorithm designed to detect features of spoken discourse was also examined. Analyses were focused on establishing the reliability and validity of these new measures. RESULTS Internal consistency was good for Swallowing (Cronbach's alpha = 0.89) and excellent for Speech and the CPIB (both Cronbach's alpha ≥ 0.94), and convergent/discriminant validity was supported. Known groups validity for the PROs was supported by significant group differences among control participants and persons with different stages of HD (all p < 0.0001). All PROs were able to distinguish those with and without clinician-rated dysarthria (likelihood ratios far exceeded the threshold for clinical decision making [all ≥ 3.28]). CONCLUSIONS Findings support the clinical utility of the HDQLIFE Speech and Swallowing PROs and the CPIB for use across the HD disease spectrum. These PROs also have the potential to be clinically useful in other populations.

J Clin Neurosci 2020; 81:133-138. [PMID: 33222902 PMCID: PMC7683823 DOI: 10.1016/j.jocn.2020.09.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2020] [Revised: 07/27/2020] [Accepted: 09/06/2020] [Indexed: 10/23/2022]
Abstract
INTRODUCTION Bulbar symptoms are frequent in patients with rapid-onset dystonia-parkinsonism (RDP). RDP is caused by ATP1A3 mutations, with onset typically within 30 days of stressor exposure. Most patients have impairments in speech (dysarthria) and voice (dysphonia). These have not been quantified. We aimed to formally characterize these in RDP subjects as compared to mutation negative family controls. METHODS We analyzed recordings in 32 RDP subjects (male = 21, female = 11) and 29 mutation negative controls (male = 15, female = 14). Three raters, blinded to mutation status, rated speech and vocal quality. Dysarthria was classified by subtype. Dysphonia was rated via the GRBAS (Grade, Roughness, Breathiness, Asthenia, Strain) scale. We used general neurological exams and the Burke-Fahn-Marsden Dystonia Rating Scale (BFMDRS) to assess dysarthria, dystonia, and speech/swallowing dysfunction. RESULTS The presence of dysarthria was more frequent in RDP subjects compared to controls (72% vs. 17%, p < 0.0001). GRBAS voice ratings were worse in the RDP cohort across nearly all categories. Dysarthria in RDP was associated with concordant cranial nerve 9-11 dysfunction (54%, p = 0.048), speech/swallowing dysfunction (96%, p = 0.0003); and oral dystonia (88%, p = 0.001). CONCLUSIONS Quantitative voice and speech analyses are important in assessing RDP. Subjects frequently experience dysarthria and dysphonia. Dystonia is not the exclusive voice abnormality present in this population. In our analysis, RDP subjects more frequently experienced bulbar symptoms than controls. GRBAS scores are useful in quantifying voice impairment, potentially allowing for better assessments of progression or treatment effects. Future directions include using task-specific diagnostic and perceptual voice evaluation tools to further assess laryngeal dystonia.

Abstract
Essential tremor is one of the most common tremor syndromes. According to the recent tremor classification, tremor as a symptom is defined as an involuntary, rhythmic, oscillatory movement of a body part and is classified along two axes: axis 1-defining syndromes based on the clinical features such as historical features, tremor characteristics, associated signs, and laboratory tests; and axis 2-classifying the etiology (Bhatia et al., Mov Disord 33:75-87, 2018). The management of this condition has two major approaches. The first is to exclude treatable etiologies, as particularly during the onset of this condition the presentation of a variety of etiologies can be with monosymptomatic tremor. Once the few etiologies with causal treatments are excluded, all further treatment is symptomatic. Shared decision-making with enabling the patient to knowledgeably choose treatment options is needed to customize the management. Mild to moderate tremor severity can sometimes be controlled with occupational treatment, speech therapy of psychotherapy, or adaptation of coping strategy. First-line pharmacological treatments include symptomatic treatment with propranolol, primidone, and topiramate. Botulinum toxin is for selected cases. Invasive treatments for essential tremor should be considered for severe tremors. They are generally accepted as the most powerful interventions and provide not only improvement of tremor but also a significant improvement of life quality. The current standard is deep brain stimulation (DBS) of the thalamic and subthalamic region. Focused ultrasound thalamotomy is a new therapy attracting increasing interest. Radiofrequency lesioning is only rarely done if DBS or focused ultrasound is not possible. Radiosurgery is not well established. We present our treatment algorithm.

Abstract
Background Palato-pharyngo-laryngeal myoclonus, a variant of palatal myoclonus, is characterized by involuntary rhythmic movements of palatal, pharyngeal, and laryngeal muscles. Symptomatic palatal myoclonus is classically associated with hypertrophic olivary degeneration on MRI imaging due to a lesion in the triangle of Guillain-Mollaret. Case presentation We report a case of palato-pharyngo-laryngeal myoclonus in a patient post-cerebellar hemorrhagic stroke who presented with recurrent retrograde migration of his gastrojejunostomy feeding tubes. Treatment with either divalproex sodium or gabapentin resulted in a significant decrease in his gastrointestinal symptoms and no further episodes of gastrojejunostomy tube migration. Conclusions This case study indicates that the movement disorder associated with hypertrophic olivary degeneration may involve the gastrointestinal system. Anticonvulsants, such as gabapentin and divalproex sodium, may reduce the severity of gastrointestinal symptoms in cases associated with hypertrophic olivary degeneration. The anatomy of the Guillain-Mollaret triangle and the pathophysiology of hypertrophic olivary degeneration are reviewed.

Abstract
Oro-pharyngeal dysphagia is a common symptom in patients with Parkinson’s disease (PD) and related disorders, even in their early stage of diseases. Dysphagia in these patients has been underdiagnosed, probably due to poor the self-awareness of the conditions and the underuse of validated tools and objective instruments for assessment. The early detection and intervention of dysphagia are closely related to improving the quality of life and decreasing the mortality rate in these patients. The purpose of this paper is to give an overview of the characteristics of dysphagia, including the epidemiology, pathophysiology, and clinical symptomatology, in patients with PD compared with other parkinsonian disorders and movement disorders. The management of dysphagia and future research directions related to these disorders are also discussed.

Abstract
OBJECTIVES To compare signs and symptoms of dysphagia in individuals with cervical dystonia (CD) before and after application of botulinum toxin (BTX). METHODS A prospective study was conducted with 20 patients diagnosed with CD with indications for BTX application. We selected 18 patients who met the study inclusion criteria. All individuals were patients from the Movement Disorders Unit, Department of Neurology, Federal University of São Paulo. BTX was applied in the cervical region at the necessary dose for each individual. To identify signs/complaints of changes in swallowing, we used a specific questionnaire that was completed by patients and/or their companions on the day of BTX injection and repeated 10 to 15 days after BTX injection. RESULTS Among the 18 study subjects, 15 (83.3%) showed primary and three (16.7%) showed secondary cervical dystonia. The most frequent dystonic movements were rotation (18), tilt (5), forward shift (3), backward shift (7), shoulder elevation (12), shoulder depression (2), and cervical tremor (6). The main complaints reported before BTX application were voice changes in 10 (55.6%), need for adjustment of eating position in 10 (55.6%), coughing and/or choking while eating in nine (50%), and increased eating time in nine (50%) individuals. The main complaints reported after BTX application were coughing and/or choking while eating in 11 (61.1%), voice changes in nine (50%), sensation of food stuck in the throat in eight (44%), and increased eating time in eight (44%) individuals. CONCLUSION The administration of a swallowing-specific questionnaire to individuals with CD before and after BTX application enabled the identification of possible dysphagia symptoms prior to drug treatment resulting from CD, which are often subsequently interpreted as side effects of the drug treatment. Thus, dysphagia can be managed, and aspiration symptoms can be prevented.

Abstract
Cortical auditory evoked potentials (CAEP) throughout a language task is beneficial during psychophysiological evaluation to advance identification of language disorders. So as to better comprehend human communication and to provide additional elements for neuropsychological examinations we aimed to (1) examine the influence of language tasks on cortical auditory processing and vagal control of heart rate and (2) to verify a possible association between the parasympathetic cardiac regulation and cortical auditory processing in language tasks. This study was completed with 49 women. The subjects were separated into two groups: (1) phonological language tasks (N = 21) and (2) semantic (N = 21) language tasks. Heart rate variability (HRV) and CAEP were evaluated before and after the tests. HRV reduced (small effect size) and P3 wave latency increased after the phonological task. Identical variables were significantly correlated after the phonological task and linear regression indicated significant interaction between pNN50 (percentage of adjacent RR intervals with a difference of duration greater than 50 milliseconds) and P3 latency (16.9%). In conclusion, phonological language tasks slightly reduced parasympathetic control of HR and increased cognitive effort. The association between HRV and CAEP are anticipated to be involved in this mechanism.
