    • Abstract: Objective To evaluate the accuracy and quality of Korean videos associated with restless legs syndrome (RLS) on YouTube.MethodsA YouTube search was performed on April 1, 2020 using the term “restless legs syndrome” in the Korean language. Two reviewers coded the source, content, and demographics of the included videos. Video quality was assessed using the modified DISCERN (mDISCERN) instrument.ResultsAmong the 80 videos analyzed, 44 (55.0%) were reliable, and 36 (45.0%) were misleading. There was a trend toward a higher number of mean daily views in the misleading videos than in the reliable videos. Most of the misleading videos (72.2%) advocated complementary and alternative medicine as a primary treatment for RLS. Although the reliable videos had higher mDISCERN scores than the misleading videos, the overall quality of the reliable videos was low.ConclusionMany Korean videos regarding RLS on YouTube involve a risk of exposure to misinformation and are of unsatisfactory quality.

  • Factors Associated with Medication Beliefs in Patients with Parkinson

    • Abstract: ObjectiveMedication beliefs are a significant determinant of medication adherence in chronic illness. This study aimed to identify demographic, clinical, and medication-related factors associated with medication beliefs in patients with Parkinson’s disease (PD).MethodsWe used a descriptive cross-sectional design with a convenience sample of 173 PD patients who had been taking antiparkinson drugs for more than one year.ResultsThe subjects who believed PD medication was more necessary had more severe illness, younger age of onset, longer illness duration, and longer duration of levodopa therapy. They had higher levels of non-motor symptoms and depression, number of medication uses, number of drugs, and levodopa equivalent dose, and they reported fluctuation of motor symptoms and dyskinesia. The subjects who used catechol-O-methyltransferase (COMT) inhibitors, dopamine agonists, amantadine, and monoamine oxidase-B (MAO-B) inhibitors had significantly higher necessity scores than those who did not use them. The subjects who had higher concerns about PD medications had higher levels of non-motor symptoms and depression. The subjects using amantadine and anticholinergics had significantly higher concern scores than those who did not use them. Positive necessity-concerns differentials were associated with severe illness, the presence of motor fluctuation and dyskinesia, and the use of COMT inhibitors. Based on stepwise multiple regression, the most significant factors influencing necessity beliefs were severe illness, followed by depression and motor fluctuation.ConclusionSevere illness, higher levels of depression, and motor fluctuation are independent factors influencing patients’ beliefs regarding medication necessity. Therefore, these characteristics should be considered in medication belief assessment and interventions for PD patients.

  • Patient Knowledge, Attitude and Perceptions towards Botulinum Toxin
           Treatment for Movement ...

    • Abstract: Objective There is limited literature on the knowledge, attitude, and perceptions (KAP) of botulinum toxin (BoNT) treatment among patients and caregivers. The objective of this study was to assess the KAP in patients undergoing BoNT treatment for movement disorders.Methods One hundred patients with movement disorders from National Institute of Mental Health and Neurosciences Hospital in Bengaluru, South India, were recruited. The patients underwent demographic, clinical, and Patient Knowledge Questionnaire on Botulinum Toxin Use in Movement Disorders (PKQ-BMD)-based evaluations.Results The mean age of patients at the time of presentation was 47.97 ± 14.19 years (range, 12'79). Of all the patients, 26 (28%) patients were anxious, and 86% of these patients were reassured after appropriate counseling. There were 83 (89%) patients who found BoNT to be a costlier option. Education and previous Internet searches influenced positive performance in the “knowledge” domain and overall PKQ-BMD scores. The “number of injections” was also positively correlated with KAP performance.Conclusion This study showed that knowledge and perceptions about BoNT treatment need to be further improved. Wider availability of the Internet has provided a positive impact on patients’ and carers’ KAP. Internet-based information, higher educational qualifications of the patients, and a higher number of BoNT injection sessions are the most important predictors of satisfactory KAP related to BoNT injection treatment in patients with movement disorders.

  • Myoclonus-Ataxia Syndrome Associated with COVID-19

    • Abstract: Neurological manifestations of coronavirus disease (COVID-19) have increasingly been reported since the onset of the pandemic. Herein, we report a relatively new presentation. A patient in the convalescence period following a febrile illness with lower respiratory tract infection (fever, myalgia, nonproductive cough) presented with generalized disabling myoclonus, which is phenotypically suggestive of brainstem origin, along with additional truncal cerebellar ataxia. His neurology work-ups, such as brain MRI, electroencephalography, serum autoimmune and paraneoplastic antibody testing, were normal. His CT chest scan revealed right lower lung infiltrates, and serological and other laboratory testing did not show evidence of active infection. COVID-19 titers turned out to be strongly positive, suggestive of post-COVID-19 lung sequelae. He responded partially to antimyoclonic drugs and fully to a course of steroids, suggesting a para- or postinfectious immune-mediated pathophysiology. Myoclonusataxia syndrome appears to be a neurological manifestation of COVID-19 infection, and knowledge regarding this phenomenon should be increased among clinicians for better patient care in a pandemic situation.

  • Manganese and Movement Disorders: A Review

    • Abstract: Scientific and technological advances achieved with industrial expansion have led to an ever-increasing demand for heavy metals. This demand has, in turn, led to increased contamination of soil, water and air with these metals. Chronic exposure to metals may be detrimental not only to occupational workers but also to the nonoccupational population exposed to these metals. Manganese (Mn), a commonly used heavy metal, is an essential cofactor for many enzymatic processes that drive biological functions. However, it is also a potential source of neurotoxicity, particularly in the field of movement disorders. The typical manifestation of Mn overexposure is parkinsonism, which may be difficult to differentiate from the more common idiopathic Parkinson’s disease. In addition to environmental exposure to Mn, other potential etiologies causing hypermanganesemia include systemic health conditions, total parenteral nutrition and genetic mutations causing Mn dyshomeostasis. In this review, we critically analyze Mn and discuss its sources of exposure, pathophysiology and clinical manifestations. We have highlighted the global public health impact of Mn and emphasize that movement disorder specialists should record a detailed social and occupational history to ensure that a toxic etiology is not misdiagnosed as a neurodegenerative disease. In the absence of a definite therapeutic option, early diagnosis and timely institution of preventive measures are the keys to managing its toxic effects.

  • Telemedicine in an Academic Movement Disorders Center during COVID-19

    • Abstract: Objective Telemedicine has rapidly gained momentum in movement disorder neurology during the coronavirus disease (COVID-19) pandemic to preserve clinical care while mitigating the risks of in-person visits. We present data from the rapid implementation of virtual visits in a large, academic, movement disorder practice during the COVID-19 pandemic.Methods We describe the strategic shift to virtual visits and retrospectively examine elements that impacted the ability to switch to telemedicine visits using historical prepandemic in-person data as a comparator, including demographics, distance driven, and diagnosis distribution, with an additional focus on patients with deep brain stimulators.Results A total of 686 telemedicine visits were performed over a five-week period (60% of those previously scheduled for in-office visits). The average age of participants was 65 years, 45% were female, and 73% were Caucasian. Men were more likely to make the transition (p = 0.02). Telemedicine patients lived farther from the clinic than those seen in person (66.47 km vs. 42.16 km, p < 0.001), age was not associated with making the switch, and patient satisfaction did not change. There was a significant shift in the distribution of movement disorder diagnoses seen by telemedicine compared to prepandemic in-person visits (p < 0.001). Patients with deep brain stimulators were more likely to use telemedicine (11.5% vs. 7%, p < 0.001).Conclusion Telemedicine is feasible, viable and relevant in the care of movement disorder patients, although health care disparities appear evident for women and minorities. Patients with deep brain stimulators preferred telemedicine in our study. Further study is warranted to explore these findings.

  • Immune-Mediated Cerebellar Ataxias: Clinical Diagnosis and Treatment Based
           on Immunological and ...

    • Abstract: Since the first description of immune-mediated cerebellar ataxias (IMCAs) by Charcot in 1868, several milestones have been reached in our understanding of this group of neurological disorders. IMCAs have diverse etiologies, such as gluten ataxia, postinfectious cerebellitis, paraneoplastic cerebellar degeneration, opsoclonus myoclonus syndrome, anti-GAD ataxia, and primary autoimmune cerebellar ataxia. The cerebellum, a vulnerable autoimmune target of the nervous system, has remarkable capacities (collectively known as the cerebellar reserve, closely linked to plasticity) to compensate and restore function following various pathological insults. Therefore, good prognosis is expected when immune-mediated therapeutic interventions are delivered during early stages when the cerebellar reserve can be preserved. However, some types of IMCAs show poor responses to immunotherapies, even if such therapies are introduced at an early stage. Thus, further research is needed to enhance our understanding of the autoimmune mechanisms underlying IMCAs, as such research could potentially lead to the development of more effective immunotherapies. We underscore the need to pursue the identification of robust biomarkers.

  • Impact of Upper Eyelid Surgery on Symptom Severity and Frequency in Benign
           Essential Blepharospasm

    • Abstract: Objective To assess the impact of periocular surgery, other than orbicularis stripping, on the severity and frequency of blepharospasm symptoms.Methods Consecutive patients with benign essential blepharospasm (BEB) who underwent eyelid/eyebrow surgery with the aim of improving symptoms were retrospectively reviewed over a 5-year period. Patients who had completed the Jankovic Rating Scale (JRS) and Blepharospasm Disability Index (BDI) pre- and at least 3 months postoperatively were included.Results Twenty-four patients were included. JRS scores significantly improved from 7.0 preoperatively to 4.1 postoperatively (p < 0.001), and BDI scores significantly improved from 18.4 preoperatively to 12.7 postoperatively (p < 0.001); the mean percentage improvements were 41% and 30%, respectively. Patients were followed for a median of 24 months postoperatively.Conclusion Periocular surgery significantly reduced BEB symptoms in the majority (83%) of patients by an average of 33% and may therefore be offered for suitable patients. An important minority (17%) of patients experienced symptom worsening.

  • Health-Related Quality of Life for Parkinson

    • Abstract: Objective Motor and non-motor symptoms (NMS) negatively impact the health-related quality of life (HRQoL) for individuals with Parkinson’s disease (PD), as well as their caregivers. NMS can emerge decades prior to the manifestation of motor symptoms but often go unrecognized and therefore untreated. To guide clinical management, we surveyed differences and identified factors that influence HRQoL in a cohort of PD patients and family caregivers.Methods A total of 103 PD patients were compared with 81 caregivers. Outcome measures collected from validated questionnaires included generic and disease-specific HRQoL assessments, depression frequency and severity, constipation severity, upper and lower gastrointestinal symptoms, physical activity and motor symptom severity.Results PD patients reported significantly decreased physical and mental HRQoL compared to their caregivers (both p < 0.001). Unemployment, the need for social support services, rehabilitation use, REM sleep behavior disorder, impulse control disorders and features suggestive of increasing disease severity hallmarked by increasing PD duration, higher MDS UPDRS-III (Movement Disorder Society'Unified Parkinson’s Disease Rating Scale'Part III) scores, higher daily levodopa equivalence dose and motor fluctuations were consistent with a lower HRQoL in our PD cohort. Furthermore, decreased physical activity, chronic pain, depression, constipation and upper gastrointestinal dysfunction (particularly indigestion, excess fullness and bloating) suggested vulnerability to reduced HRQoL. Overall, PD patients perceived their health to decline by 12% more than their caregivers did over a 1-year period.Conclusion PD patients reported decreased HRQoL, with both motor symptoms and NMS negatively impacting HRQoL. Our findings support the routine clinical screening of HRQoL in PD patients to identify and address modifiable factors.

  • The Queensland Parkinson

    • Abstract: Objective The consensus is that life expectancy for individuals with Parkinson’s disease (PD) is reduced, but estimations vary. We aimed to provide an overview of 20 years of mortality and risk factor data from the Queensland Parkinson’s Project.Methods The analysis included 1,334 PD and 1,127 control participants. Preliminary analysis of baseline characteristics (sex, age at onset, family history, smoking status, pesticide exposure, depression and neurosurgery) was conducted, and Kaplan'Meier curves were generated for each potential risk factor. Standardized mortality ratios (SMRs) were calculated comparing this cohort to the general Australian population. Cox proportional hazards regression modeling was used to analyze potential predictors of mortality.Results In total, 625 (46.8%) PD and 237 (21.0%) control participants were deceased. Mean disease duration until death was 15.3 ± 7.84 years. Average ages at death were 78.0 ± 7.4 years and 80.4 ± 8.4 years for the deceased PD and control participants, respectively. Mortality was significantly increased for PD in general {SMR = 2.75 [95% confidence interval (CI): 2.53'2.96]; p = 0.001}. SMRs were slightly higher for women and those with an age of onset before 60 years. Multivariate analysis showed that deep brain stimulation (DBS) treatment was associated with lower mortality [hazard ratio (HR) = 0.76; 95% CI: 0.59'0.98], while occasional pesticide exposure increased mortality risk (HR = 1.48; 95% CI: 1.17'1.88). Family history of PD, smoking and depression were not independent predictors of mortality.Conclusion Mortality in PD is increased. Sex, age at onset and occasional pesticide exposure were independent determinants of increased mortality, while DBS treatment was associated with reduced mortality.

           COVID-19 Pneumonia

    • Abstract: Hydroxychloroquine (HCQ) has been used as an investigational drug for patients with moderate to severe coronavirus disease 2019 (COVID-19). There have been concerns of potential harms from side effects of the drug. We present a case of a 38-year-old male who was started on HCQ for COVID-19 pneumonia. He was referred for evaluation of myoclonus of all extremities, which resolved after discontinuation of HCQ. The involuntary movements were first reported after the initiation of HCQ, persisted despite improvement in inflammatory and radiologic parameters and eventually resolved after HCQ discontinuation. This supports a possible causality related to adverse drug reactions from HCQ that have not been commonly reported.

  • Sialidosis Type I without a Cherry Red Spot' Is There a Genetic
           Basis'

    • Abstract: Sialidosis is an inborn error of metabolism due to a defect in the NEU1 gene and manifests as two phenotypes: mild type I and severe type II. The cherry red spot (CRS) is a characteristic feature in both types of sialidosis; reports of sialidosis without a CRS are rare. We report two cases of genetically confirmed sialidosis type I with a typical presentation of progressive cortical myoclonus and ataxia but without the CRS. A previously reported homozygous pathogenic variant p.Arg294Cys was detected in the first case, and a novel homozygous pathogenic variant p.Arg305Pro was detected in the second case. Additionally, we reviewed the literature describing cases with similar mutations to find a genetic basis for the absence of a CRS. Milder mutation of both alleles detected in both patients may be the reason for the absence of a CRS.

    • Abstract: The genetic testing of hereditary ataxias includes screening for CAG-repeat expansions as well as pathogenic variants and nontranslated oligonucleotide expansion, which can cause spinocerebellar ataxia (SCA). Genotype-phenotype correlations of several SCA subtypes are difficult to establish, and the underlying mechanisms remain unclear. Here, we report a 58-year-old male patient who presented with severe generalized ataxia, horizontal gaze-evoked nystagmus, cognitive impairment and a positive family history of gait difficulties. Genetic panel diagnostics revealed a new nonsense pathogenic variant in the CACNA1A gene (c.2983G>T; p. Glu995*) that segregated with the phenotype in three clinically affected family members. This gene is related to SCA type 6 (SCA6), episodic ataxia type 2, familial hemiplegic migraine type 1, among others. When it is supported by the clinical findings and family history, additional DNA sequencing beyond fragment length analysis should be performed.

  • Perry Disease: Concept of a New Disease and Clinical Diagnostic Criteria

    • Abstract: Perry disease is a hereditary neurodegenerative disease with autosomal dominant inheritance. It is characterized by parkinsonism, psychiatric symptoms, unexpected weight loss, central hypoventilation, and transactive-response DNA-binding protein of 43kD (TDP-43) aggregation in the brain. In 2009, Perry disease was found to be caused by dynactin I gene (DCTN1), which encodes dynactin subunit p150 on chromosome 2p, in patients with the disease. The dynactin complex is a motor protein that is associated with axonal transport. Presently, at least 8 mutations and 22 families have been reported; other than the “classic” syndrome, distinct phenotypes are recognized. The neuropathology of Perry disease reveals severe degeneration in the substantia nigra and TDP-43 inclusions in the basal ganglia and brain stem. How dysfunction of the dynactin molecule is related to TDP-43 pathology in Perry disease is important to elucidate the pathological mechanism and develop new treatment.

    • Abstract: Objective Willingness to undergo deep brain stimulation (DBS) among patients with Parkinson’s disease (PD) and their overall satisfaction with the procedure is highly dependent upon expectations, which are based on the core concepts of knowledge, attitude and perceptions. The present study aims to evaluate these factors in patients and caregivers with PD from a single tertiary care hospital in India.Methods A structured questionnaire designed to assess the knowledge, attitude and perceptions about DBS in PD was administered to 400 patients with PD and their caregivers.Results A very small proportion of patients and caregivers were aware of DBS. Even those who claimed to be aware of DBS were inadequately informed and had incorrect knowledge, which led to wrong attitudes and perceptions.Conclusion There are very significant knowledge gaps and misconceptions regarding DBS among patients with PD and caregivers. Adequate and appropriate education is necessary to clarify these misconceptions to avoid the development of unrealistic expectations and poor satisfaction.

    • Abstract: F-box only protein 7 (FBXO7) is a rare monogenic cause of hereditary Parkinson’s disease (PD) with an autosomal recessive mode of inheritance and a broad spectrum of clinical manifestations. Here, we report a de novo PD patient with onset at the age of 28 with novel compound heterozygous variants in the FBXO7 gene (c.1162C>T, p.Gln388X; c.80G>A, p.Arg27His). The clinical features of the patient were problematic impulse control disorder behaviors and pyromania, and pyramidal signs were negative. We describe the novel pathogenic variants of the FBXO7 gene with detailed clinical pictures to report the expanding genotypes and phenotypes of FBXO7-associated parkinsonism.

           in Patients with Parkinson

    • Abstract: Objective To investigate the efficacy of levodopa/carbidopa/entacapone (LCE) at bedtime for treating sleep disturbance in patients with Parkinson’s disease (PD) with motor fluctuations.Methods Participants included 128 PD patients with motor fluctuations. All patients were assessed for motor, nonmotor, and sleep-specific symptoms using the United Parkinson’s Disease Rating Scale (UPDRS), the Korean version of the Nonmotor Symptom Scale, the Parkinson’s Disease Sleep Scale (PDSS), the Epworth Sleepiness Scale, and the Rapid Eye Movement Sleep Behavior Disorder Screening Questionnaire (RBDSQ). We compared the baseline characteristics of patients with sleep disturbance (PDSS score < 120) and those without sleep disturbance (PDSS score ≥ 120). Thirty-nine patients with sleep disturbance who agreed to take LCE at bedtime completed 3-month follow-ups. We analyzed changes in the scores of motor, nonmotor, and sleep symptom scales over the 3 months.Results PD patients with sleep disturbance were at more advanced disease stages and had more severe motor, nonmotor, and sleep symptoms than those without sleep disturbance. Patients who took LCE at night showed improvements in motor (UPDRS part III, p = 0.007) and sleep symptoms (total PDSS, p < 0.001). Sleep features that benefitted from LCE included not only nocturnal motor components but also insomnia (PDSS items 2 and 3, p = 0.005 and p < 0.001) and rapid eye movement behavior disorder (PDSS item 6, p = 0.002; and RBDSQ, p < 0.001).Conclusion The use of LCE at bedtime may be a useful treatment for sleep disturbance in advanced PD patients with motor fluctuations.

  • Emerging Concepts of Motor Reserve in Parkinson

    • Abstract: The concept of cognitive reserve (CR) in Alzheimer’s disease (AD) explains the differences between individuals in their susceptibility to AD-related pathologies. An enhanced CR may lead to less cognitive deficits despite severe pathological lesions. Parkinson’s disease (PD) is also a common neurodegenerative disease and is mainly characterized by motor dysfunction related to striatal dopaminergic depletion. The degree of motor deficits in PD is closely correlated to the degree of dopamine depletion; however, significant individual variations still exist. Therefore, we hypothesized that the presence of motor reserve (MR) in PD explains the individual differences in motor deficits despite similar levels of striatal dopamine depletion. Since 2015, we have performed a series of studies investigating MR in de novo patients with PD using the data of initial clinical presentation and dopamine transporter PET scan. In this review, we summarized the results of these published studies. In particular, some premorbid experiences (i.e., physical activity and education) and modifiable factors (i.e., body mass index and white matter hyperintensity on brain image studies) could modulate an individual’s capacity to tolerate PD pathology, which can be maintained throughout disease progression.

  • Effectiveness of Exercise on the Sequence Effect in Parkinson

    • Abstract: Objective To determine the benefits of motor training on the sequence effect (SE), an essential component of bradykinesia in Parkinson’s disease (PD).Methods Seven patients with de novo PD participated in this study. The patients performed regular pentagon drawing tests and exercises during four visits. The first two visits occurred before the start of medication, and the last two visits occurred at least six months after the start of medication. We assessed the severity of bradykinesia and SE at each visit and compared the results before and after exercise in both the de novo and treatment conditions.Results In the de novo condition, the severity of bradykinesia significantly improved after motor training (p = 0.018), but it did not resolve and only showed a trend of improvement after treatment (p = 0.068). The severity of the SE decreased significantly in the drug-na've condition (p = 0.028) but not after medication (p = 0.273).Conclusion Our study suggests that regular motor training may be beneficial for the SE in PD.

  • Update on Current Technologies for Deep Brain Stimulation in Parkinson

    • Abstract: Deep brain stimulation (DBS) is becoming increasingly central in the treatment of patients with Parkinson’s disease and other movement disorders. Recent developments in DBS lead and implantable pulse generator design provide increased flexibility for programming, potentially improving the therapeutic benefit of stimulation. Directional DBS leads may increase the therapeutic window of stimulation by providing a means of avoiding current spread to structures that might give rise to stimulation-related side effects. Similarly, control of current to individual contacts on a DBS lead allows for shaping of the electric field produced between multiple active contacts. The following review aims to describe the recent developments in DBS system technology and the features of each commercially available DBS system. The advantages of each system are reviewed, and general considerations for choosing the most appropriate system are discussed.

We report our experience with the management of acute worsening of symptoms due to battery exhaustion in 3 patients with DBS.Methods Patients with DBS for movement disorders who visited the emergency room due to battery exhaustion during the nationwide lockdown from April to May 2020 were included.Results Two patients with subthalamic nucleus-DBS for Parkinson’s disease (PD) and one with globus pallidus interna-DBS for generalized dystonia presented with acute worsening of symptoms due to battery exhaustion. Urgent battery replacement was performed in both patients with PD. The patient with generalized dystonia was managed with medication adjustment as he chose to defer battery replacement.Conclusion DBS battery replacement can be an emergency. Decisions regarding DBS battery replacement should be individualized during this COVID-19 pandemic.

  • Parkinson Anxiety Scale: A Validation Study for the Brazilian Population

    • Abstract: Objective The Parkinson Anxiety Scale (PAS) was developed to measure the severity of anxiety symptoms in patients with Parkinson’s disease (PD), and it has not yet been adapted and validated in Portuguese. Thus, this study evaluated the reliability and validity of a translated and adapted version of the PAS for the Brazilian population of PD patients.Methods The Parkinson Anxiety Scale ' Brazilian Version (PAS-BV) was completed by 55 patients with PD. The reliability (test-retest reliability, interrater reliability and internal consistency) and construct validity of the PAS-BV were assessed by comparing it with the Beck Anxiety Inventory (BAI), the Parkinson’s Disease Fatigue Scale (PFS) and the Unified Parkinson Disease Rating Scale (UPDRS) part III.Results Patients with PD had an average age of 64.51 ± 9.20 years and had PD for an average of 6.98 ± 5.02 years. The reliability of the PAS-BV was 0.83, and the intraclass correlation coefficient (ICC) (retest-test) was 0.88. The scale presented good convergent validity with the BAI (rs = 0.82, p < 0.05). It also presented good divergent validity with the PFS (rs = 0.24, p> 0.05) and the UPDRS part II (rs = -0.10, p> 0.05), part III (rs = -0.21, p> 0.05), and part IV (rs = 0.03, p> 0.05), as indicated by the absence of significant correlations. However, there was a significant correlation between the PAS-BV and part I of the UPDRS (rs = 0.67, p < 0.05).Conclusion The PAS-BV presents substantial reliability and validity for patients with PD without dementia.

A 55-year-old man presented with left ear clicking and hyperacusis. Examination showed arrhythmic left lateral soft palate contraction in the tensor veli palatini region without elevation of the uvula, which correlated with an audible click by auscultation with a stethoscope over the left ear. This is a rare case of focal, unilateral palatal myoclonus without visual uvula elevation with concurrent auscultation, demonstrating the importance of careful examination to detect focal myoclonic contractions.

  • Long-Term Outcomes of Genetic Parkinson

    • Abstract: Parkinson’s disease (PD) is a progressive neurodegenerative disorder that affects 1?2% of people by the age of 70 years. Age is the most important risk factor, and most cases are sporadic without any known environmental or genetic causes. Since the late 1990s, mutations in the genes SNCA, PRKN, LRRK2, PINK1, DJ-1, VPS35, and GBA have been shown to be important risk factors for PD. In addition, common variants with small effect sizes are now recognized to modulate the risk for PD. Most studies in genetic PD have focused on finding new genes, but few have studied the long-term outcome of patients with the specific genetic PD forms. Patients with known genetic PD have now been followed for more than 20 years, and we see that they may have distinct and different prognoses. New therapeutic possibilities are emerging based on the genetic cause underlying the disease. Future medication may be based on the pathophysiology individualized to the patient’s genetic background. The challenge is to find the biological consequences of different genetic variants. In this review, the clinical patterns and long-term prognoses of the most common genetic PD variants are presented.

  • Nutrition and Lifestyle Interventions for Managing Parkinson

    • Abstract: The etiology of Parkinson’s disease (PD) is not fully understood, but environmental toxin overexposure, increased intestinal permeability, and dysbiosis related to nutrition and lifestyle habits are thought to be contributors. Considering these nutrition and lifestyle implications, there is a lack of practice-based programs utilizing interventions for managing symptoms or slowing the progression of the disease. The purpose of this narrative review was to identify relevant research related to nutrition and lifestyle interventions for PD, evaluate the research utilizing the evidence analysis process of the Academy of Nutrition and Dietetics to assess the quality of each research article, and group the research into categories. A grading of recommendations assessment, development and evaluation (GRADE) of either good, fair, limited, or not assignable was allocated to each category of research, including diet patterns, vitamin D, B-complex, omega-3 fatty acids, coenzyme Q10, probiotics, physical activity, stress, and sleep. An intervention based on the research presented in the review may be utilized for coaching people with PD on symptom management.

           Postural Instability and ...

    • Abstract: Objective The long-term effects of bilateral subthalamic nucleus deep brain stimulation (STN-DBS) on postural instability and gait difficulty (PIGD) in patients with Parkinson’s disease (PD) remain unclear. In this study, we aimed to evaluate the longterm effects of STN-DBS surgery on PIGD symptoms in patients with advanced-stage PD. Methods This study included 49 consecutively included patients with PD who underwent bilateral STN-DBS. The Unified Parkinson’s Disease Rating Scale (UPDRS) scores and subscores for PIGD were assessed at baseline and at 1, 3, and 5 years postoperatively. The PIGD subscore was divided into PIGD-motor and PIGD-activities of daily living (ADL) scores according to parts III and II of the UPDRS, respectively. Results The PIGD-motor and PIGD-ADL scores at the “medication-off” state improved at 3 and 5 years, respectively. Overall, the UPDRS III and II scores at “medication-off” improved at 5 years. The UPDRS IV score also significantly improved and the levodopa equivalent daily dosage decreased at all follow-ups. Finally, the PIGD-motor score at baseline was able to predict long-term improvement in the PIGD-motor score at the 5-year follow-up. Conclusion The STN-DBS has both short- and long-term effects on PIGD, as well as overall motor function, in patients with advanced PD. The degree of PIGD at the preoperative evaluation can be used to predict long-term outcomes after STN-DBS surgery.

  • Risk Factors for Falls in Patients with de novo Parkinson

    • Abstract: Objective We aimed to identify risk factors for falls in patients with de novo Parkinson’s disease (PD). Methods Forty-six patients with de novo PD were retrospectively included in the study. We assessed details on the patients’ motor symptoms as well as non-motor symptoms using several representative scales for global cognition, depression, fatigue, and dysautonomia. Fallers and non-fallers were identified according to their history of falls during the preceding year. Results Twenty-two patients (45.8%) with de novo PD had a history of falls. Compared with the non-faller group, the faller group exhibited higher scores for postural instability/gait difficulty (PIGD), anxiety, fatigue, total dysautonomia, gastrointestinal dysfunction, and thermoregulatory dysfunction. Moreover, logistic regression analysis showed that falling was positively correlated with anxiety and gastrointestinal symptoms but negatively associated with the tremor scores. Conclusion Our findings suggest that falling in patients with de novo PD is significantly associated with PIGD/non-tremor symptoms, anxiety, and gastrointestinal dysfunction.

  • Sedentary Time is Associated with Worse Attention in Parkinson

    • Abstract: Objective Cognitive symptoms of Parkinson’s disease (PD) may be alleviated by moderate-to-vigorous physical activity (MVPA), but no published research has characterized the relationship between objectively measured sedentary behavior and cognitive symptoms of PD. Therefore, the objective of this study was to assess the cross-sectional relationship between sedentary time and cognitive performance in a small pilot sample of individuals with mild-to-moderate PD. Methods Objective measures of sedentary time were obtained using an armband accelerometer. Cognition was assessed with the Parkinson’s Disease Cognitive Rating Scale and a computerized task-switching paradigm. Results The percentage of awake time spent in sedentary activities was negatively correlated with attention (β = -14.20, t(12) = -2.47, p = 0.03) but not other cognitive domains (p> 0.05) after controlling for MVPA and medication dosage. Conclusion Sedentary activity may have unique associations with cognition, particularly attention, over and above MVPA in individuals with PD.

  • Treatment of Acute Delirium in a Patient with Parkinson

    • Abstract: The treatment of delirium or psychosis in patients with Parkinson’s disease (PD) can be complicated by the limited number of pharmacological agents that can be used in this population. Typical and atypical antipsychotics are contraindicated, as they can worsen motor symptoms. The treatment of acute delirium is even more complicated in the hospital setting, as many medications deemed safer in this population are only available in oral form. We present a case of acute delirium in a patient with PD, likely precipitated by a polypharmacy interaction of new medications, that was successfully managed by transferring the patient to the intensive care unit and administering dexmedetomidine for 72 hours.

  • COVID-19: An Early Review of Its Global Impact and Considerations for
           Parkinson

    • Abstract: While many infectious disorders are unknown to most neurologists, COVID-19 is very different. It has impacted neurologists and other health care workers, not only in our professional lives but also through the fear and panic within our own families, colleagues, patients and their families, and even in the wider public. COVID-19 affects all sorts of individuals, but the elderly with underlying chronic conditions are particularly at risk of severe disease, or even death. Parkinson’s disease (PD) shares a common profile as an age-dependent degenerative disorder, frequently associated with comorbidities, particularly cardiovascular diseases, so PD patients will almost certainly fall into the high-risk group. Therefore, the aim of this review is to explore the risk of COVID-19 in PD based on the susceptibility to severe disease, its impact on PD disease severity, potential long-term sequelae, and difficulties of PD management during this outbreak, where neurologists face various challenges on how we can maintain effective care for PD patients without exposing them, or ourselves, to the risk of infection. It is less than six months since the identification of the original COVID-19 case on New Year’s Eve 2019, so it is still too early to fully understand the natural history of COVID-19 and the evidence on COVID-19-related PD is scant. Though the possibilities presented are speculative, they are theory-based, and supported by prior evidence from other neurotrophic viruses closely related to SARS-CoV-2. Neurologists should be on high alert and vigilant for potential acute and chronic complications when encountering PD patients who are suspected of having COVID-19.

  • The Non-Motor Symptom Profile of Progressive Supranuclear Palsy

    • Abstract: Objective Non-motor symptoms (NMSs) significantly contribute to increased morbidity and poor quality of life in patients with parkinsonian disorders. This study aims to explore the profile of NMSs in patients with progressive supranuclear palsy (PSP) using the validated Non-Motor Symptom Scale (NMSS).Methods Seventy-six patients with PSP were evaluated in this study. Motor symptoms and NMSs were evaluated using the PSP Rating Scale (PSPRS), Unified Parkinson’s Disease Rating Scale-III, Montreal Cognitive Assessment, Hamilton Depression (HAMD) and Anxiety Rating Scales, Parkinson’s Disease Sleep Scale (PDSS) and NMSS. NMS severity and prevalence were also compared between patients with PSP-Richardson syndrome (PSP-RS) and those with PSP-parkinsonism.Results All subjects in this cohort reported at least 2 NMSs. The most prevalent NMSs in patients with PSP were in the domains of sleep/fatigue, mood/cognition, and sexual function. The least prevalent NMSs were in the domains of cardiovascular including falls, and perceptual problems/hallucinations. Significant correlations were observed between the NMSS scores and HAM-D, PDSS, PSPRS scores and PSPRS sub-scores. The severity of NMSs was unrelated to the duration of illness. Patients with PSP-RS reported a higher severity of drooling, altered smell/taste, depression and altered interest in sex and a higher prevalence of sexual dysfunction.Conclusion NMSs are commonly observed in patients with PSP, and the domains of sleep, mood and sexual function are most commonly affected. These symptoms contribute significantly to disease morbidity, and clinicians should pay adequate attention to identifying and addressing these symptoms.

    • Abstract: Objective To investigate whether baseline olfactory dysfunction in Parkinson’s disease (PD) patients is associated with baseline and longitudinal motor and cognitive function.Methods We recruited 228 drug-na've PD patients who were followed for a mean of 6 years. Patients underwent the Cross-Cultural Smell Identification Test (CCSIT), a neuropsychological test, and N-(3-[18F]fluoropropyl)-2β-carbomethoxy-3β-(4-iodophenyl) nortropane positron emission tomography within 6 months of the baseline evaluation. Olfactory dysfunction was categorized as normosmia (CCSIT score ≥ 9), hyposmia (CCSIT score 5'8), and anosmia (CCSIT score ≤ 4). During the follow-up period, we investigated changes in the levodopa-equivalent dose (LED) and the occurrence of wearing-off, levodopa-induced dyskinesia, and dementia.Results Among the PD patients, 80.7% were hyposmic at the time of diagnosis, and 26.1% were anosmic. Baseline olfactory dysfunction was not associated with either initial parkinsonian motor symptoms or with the longitudinal LED increment and motor complications. Meanwhile, the anosmic group had lower baseline scores on the Korea version of the Boston Naming Test and Stroop color reading test than the normosmic and hyposmic groups. The anosmic group exhibited a higher rate of conversion to dementia than the normosmic [adjusted hazard ratio (HR) 3.99, 95% confidence interval (CI) 1.08'14.72] and hyposmic (adjusted HR 2.48, 95% CI 1.15'5.32) PD groups, regardless of baseline motor deficits and cognitive status.Conclusion Baseline olfactory dysfunction was not associated with motor deficits and complications, but it was associated with cognitive dysfunction and prognosis, suggesting that severe olfactory impairment may reflect early cortical involvement, probably in the frontotemporal region, and rapid spreading of Lewy body pathology.

  • Future of Tanscranial Magnetic Stimulation in Movement Disorders:
           Introduction of Novel Methods

    • Abstract: Transcranial magnetic stimulation (TMS) and repetitive TMS (rTMS) have been used for human physiological analyses and treatment of movement disorders. In this review, we present three new TMS utilities for scientific research or clinical application for movement disorders. 1) Confirmation of animal findings. Functional modulation of particular brain areas induced by rTMS can produce changes in task performance. This indicates that the area stimulated by rTMS should play some role in the target task. One example of this use is the study of functional differences between the presupplementary motor area (preSMA) and SMA in a sequential learning task. 2) Utility of cerebellar stimulation. Cerebellar functional changes in basal ganglia disorders are a hot topic in this field. These changes have been studied by cerebellar inhibition using a paired TMS coil experiment. Several researchers have recently used rTMS over the cerebellum as a treatment option for movement disorders. 3) rTMS enhancement of the effects of rehabilitation. The combination of rTMS and conventional rehabilitation may enhance rehabilitation efficacy. For example, rTMS over the lumbar gait (locomotion) center may enhance functional recovery of the gait more robustly than conventional rehabilitation alone in patients with a spinal cord injury.

  • Successful Pallidal Stimulation in a Patient with KMT2B-Related Dystonia

    • Abstract: Although the KMT2B gene was identified as a causative gene for early-onset generalized dystonia, the efficacy of deep brain stimulation (DBS) in KMT2B-related dystonia has not been clearly elucidated. Here, we describe a 28-year-old woman who developed generalized dystonia with developmental delay, microcephaly, short stature, and cognitive decline. She was diagnosed with KMT2B- related dystonia using whole-exome sequencing with a heterozygous frameshift insertion of c.515dupC (p.T172fs) in the KMT2B gene. Oral medications and botulinum toxin injection were not effective. The dystonia markedly improved with bilateral pallidal DBS (the Burke-Fahn-Marsden Dystonia Rating Scale score was reduced from 30 to 5 on the dystonia movement scale and from 11 to 1 on the disability scale), and she could walk independently. From this case, we suggest that bilateral globus pallidus internus DBS can be an effective treatment option for patients with KMT2B-related generalized dystonia.

  • Dopa-Responsive Dystonia: A Male Patient Inherited a Novel GCH1 Deletion
           from an Asymptomatic Mother

    • Abstract: Dopa-responsive dystonia (DRD) is a complex genetic disorder with either autosomal dominant or autosomal recessive inheritance, with autosomal dominant being more frequent. Autosomal dominant DRD is known to be caused by mutations in the GCH1 gene, with incomplete penetrance frequently reported, particularly in males. Here, we report a male patient with DRD caused by exon 1 deletion in the GCH1 gene inherited from the asymptomatic mother. The patient had an atypical presentation, notably with no dystonia, and underwent extensive workup for a myriad of neuromuscular disorders before a low-dose L-dopa trial and confirmatory genetic testing were performed. Our experience with this family highlights an atypical presentation of DRD and prompts us to consider the genetic complexity of DRD.

  • Principles of Electrophysiological Assessments for Movement Disorders

    • Abstract: Electrophysiological studies can provide objective and quantifiable assessments of movement disorders. They are useful in the diagnosis of hyperkinetic movement disorders, particularly tremors and myoclonus. The most commonly used measures are surface electromyography (sEMG), electroencephalography (EEG) and accelerometry. Frequency and coherence analyses of sEMG signals may reveal the nature of tremors and the source of the tremors. The effects of voluntary tapping, ballistic movements and weighting of the limbs can help to distinguish between organic and functional tremors. The presence of Bereitschafts-potentials and beta-band desynchronization recorded by EEG before movement onset provide strong evidence for functional movement disorders. EMG burst durations, distributions and muscle recruitment orders may identify and classify myoclonus to cortical, subcortical or spinal origins and help in the diagnosis of functional myoclonus. Organic and functional cervical dystonia can potentially be distinguished by EMG power spectral analysis. Several reflex circuits, such as the long latency reflex, blink reflex and startle reflex, can be elicited with different types of external stimuli and are useful in the assessment of myoclonus, excessive startle and stiff person syndrome. However, limitations of the tests should be recognized, and the results should be interpreted together with clinical observations.

  • Comparison of Spontaneous Motor Tempo during Finger Tapping, Toe Tapping
           and Stepping on the ...

    • Abstract: Objective Spontaneous motor tempo (SMT), observed in walking, tapping and clapping, tends to occur around 2 Hz. Initiating and controlling movement can be difficult for people with Parkinson’s (PWP), but studies have not identified whether PWP differ from controls in SMT. For community-based interventions, e.g. dancing, it would be helpful to know a baseline SMT to optimize the tempi of cued activities. Therefore, this study compared finger tapping (FT), toe tapping (TT) and stepping ‘on the spot’ (SS) in PWP and two groups of healthy controls [age-matched controls (AMC) and young healthy controls (YHC)], as SMT is known to change with age.Methods Participants (PWP; n = 30, AMC; n = 23, YHC; n = 35) were asked to tap or step on the spot at a natural pace for two trials lasting 40 seconds. The central 30 seconds were averaged for analyses using mean inter-onset intervals (IOI) and coefficient of variation (CoV) to measure rate and variability respectively.Results PWP had faster SMT than both control groups, depending on the movement modality: FT, F(2, 87) = 7.92, p < 0.01 (PWP faster than YHC); TT, F(2, 87) = 4.89, p = 0.01 (PWP faster than AMC); and SS, F(2, 77) = 3.26, p = 0.04 (PWP faster than AMC). PWP had higher CoV (more variable tapping) than AMC in FT only, F(2, 87) = 4.10, p = 0.02.Conclusion This study provides the first direct comparison of SMT between PWP and two control groups for different types of movements. Results suggest SMT is generally faster in PWP than control groups, and more variable when measured with finger tapping compared to stepping on the spot.

  • Rescue Levodopa/Carbidopa Intestinal Gel for Secondary Deep Brain
           Stimulation Failure

    • Abstract: Objective The long-term efficacy of deep brain stimulation (DBS) for motor fluctuations in advanced Parkinson’s disease (PD) has been well established; however, motor fluctuations may recur over time despite multiple adjustments of DBS settings and medications.Methods We conducted a retrospective chart review of three patients for whom levodopa-carbidopa intestinal gel (LCIG) was additionally administered as a rescue therapy for secondary DBS failure due to the recurrence of motor fluctuations.Results The three patients had advanced PD with a disease duration of 14–19 years, and had undergone DBS for motor fluctuations refractory to standard medical management. LCIG was administered to the patients because of symptom recurrence years after DBS and provided complementary effects in all patients.Conclusion The cases presented here show that rescue LCIG therapy may be a complementary treatment option for patients with post-DBS advanced PD who have a recurrence of troublesome motor complications.

  • A Case of Abnormal Postures in the Left Extremities after Pontine
           Hemorrhage: Dystonia or ...

    • Abstract: It is difficult to determine the pathoanatomical correlates of dystonia because of its complex pathophysiology, and most cases with secondary dystonia are associated with basal ganglia lesions. Moreover, it is a challenging issue that patients with abnormal postures accompanied by other neurological findings in the affected body part (e.g., sensory loss) can be diagnosed with true dystonia or pseudodystonia. Here, we report a case of abnormal postures with loss of proprioception in the left extremities after right dorsal pontine hemorrhage.
