  • 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.

    • Abstract: Palatal myoclonus generally entails a visible elevation of the palate and uvula and may be accompanied by myoclonus of other oropharyngeal muscles. 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.

  • Association between Olfactory Deficit and Motor and Cognitive Function in
           Parkinson

    • 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.
