RESUMO
BACKGROUND: Parkinson's disease (PD) and vascular parkinsonism (VaP) have highly overlapping phenotypes, and different prognosis. This study comprehensively investigated the clinical, brain MRI and transcranial sonography differences between VaP and PD. METHODS: Forty-eight patients with PD, 27 patients with VaP, and 29 healthy controls were compared. All patients were assessed using the MDS-UPDRS, Berg Balance Scale (BBS), Ten-Meter Walking Test (10-MWT), Time Up and Go Test, and Non-Motor Symptoms Scale. Beck Depression Inventory, PD questionnaire- 39, international urine incontinence scale, cognitive assessment scales, MRI brain and transcranial colour-coded doppler. The study was registered on clinical-Trial.gov (NCT04308135) on 03/12/2020. RESULTS: VaP patients showed significantly older age of onset, shorter disease duration, lower drug doses and levodopa responsiveness, higher On and Off axial scores, On and Off BBS, higher On scores for PIGD, rigidity, bradykinesia and total motor MDS-UPDRS, lower On and Off tremor, lower-half predominance, lower asymmetrical presentation and symmetric index than PD patients. VaP patients had worse non-motor symptoms Scale (NMSS) than controls except for perceptual problems/hallucinations but better symptoms than PD patients except for urinary dysfunction. Quality of life (QoL) was impaired in VaP patients and was correlated with motor function and NMSs. The VaP group had significantly higher white matter lesions and brain atrophy, with lower hyperechogenicity of the substantia nigra and more impaired cerebral vascular resistance and vasoreactivity than the PD group. CONCLUSIONS: VaP has a characteristic motor and non-motor profile, with impaired QoL, white matter, and transcranial sonography abnormalities that differentiate it from PD. Further studies are warranted to explore the role of vascular lesions in the pathogenesis of VaP. TRIAL REGISTRATION: The registered identifier NCT04308135 on clinical-Trial.gov.

BACKGROUND: Zonisamide (ZNS) has shown some efficacy in motor symptoms of PD; however, more evidence is lacking, and its effects on nonmotor symptoms (NMSs) and quality of life (QoL) remain to be investigated. This randomized double-blinded placebo-controlled crossover study investigated the effect of ZNS on motor and NMS symptoms and QoL in advanced PD. METHODS: PD patients with Hoehn and Yahr stage ≥ 2 ("On" state) and at least 2 h off time daily were randomized to groups: ZNS 25 mg, ZNS 50 mg and placebo. Groups were assessed at baseline and at the 1- and 3-month follow-ups. The primary endpoint was the change in the total MDS-UPDRS III "On", while the secondary endpoint was the change in the total and parts I and IV MDS-UPDRS, Nonmotor Symptoms Scale and Parkinson's disease questionnaire-39 at the final assessment. RESULTS: Sixty-nine patients were assessed for efficacy at the 1-month follow-up, and 58 patients were assessed at the 3-month follow-up. The primary endpoint showed significant improvement in the ZNS 25 mg group compared to the placebo group (p = 0.009). At the final assessment, the ZNS 25 mg group showed significant improvement of total and part VI MDS-UPDRS, bradykinesia, tremor and functional impact of fluctuations compared to placebo. There was no change in dyskinesia, NMSs, QoL or side effects except for sedation. CONCLUSION: ZNS has a favourable effect on motor symptoms in patients with wearing off as adjunctive therapy with other dopaminergic drugs, with no exacerbation of dyskinesia and a limited impact on NMSs and QoL.

Genetic testing for persons with Parkinson's disease is becoming increasingly common. Significant gains have been made regarding genetic testing methods, and testing is becoming more readily available in clinical, research, and direct-to-consumer settings. Although the potential utility of clinical testing is expanding, there are currently no proven gene-targeted therapies, but clinical trials are underway. Furthermore, genetic testing practices vary widely, as do knowledge and attitudes of relevant stakeholders. The specter of testing mandates financial, ethical, and physician engagement, and there is a need for guidelines to help navigate the myriad of challenges. However, to develop guidelines, gaps and controversies need to be clearly identified and analyzed. To this end, we first reviewed recent literature and subsequently identified gaps and controversies, some of which were partially addressed in the literature, but many of which are not well delineated or researched. Key gaps and controversies include: (1) Is genetic testing appropriate in symptomatic and asymptomatic individuals without medical actionability? (2) How, if at all, should testing vary based on ethnicity? (3) What are the long-term outcomes of consumer- and research-based genetic testing in presymptomatic PD? (4) What resources are needed for clinical genetic testing, and how is this impacted by models of care and cost-benefit considerations? Addressing these issues will help facilitate the development of consensus and guidelines regarding the approach and access to genetic testing and counseling. This is also needed to guide a multidisciplinary approach that accounts for cultural, geographic, and socioeconomic factors in developing testing guidelines. © 2023 The Authors.

BACKGROUND: There is growing clinical and research utilization of genetic testing in Parkinson's disease (PD), including direct-to-consumer testing. OBJECTIVES: The aim is to determine the international landscape of genetic testing in PD to inform future worldwide recommendations. METHODS: A web-based survey assessing current practices, concerns, and barriers to genetic testing and counseling was administered to the International Parkinson and Movement Disorders Society membership. RESULTS: Common hurdles across sites included cost and access to genetic testing, and counseling, as well as education on genetic counseling. Region-dependent differences in access to and availability of testing and counseling were most notable in Africa. High-income countries also demonstrated heterogeneity, with European nations more likely to have genetic testing covered through insurance than Pan-American and Asian countries. CONCLUSIONS: This survey highlights not only diversity of barriers in different regions but also the shared and highly actionable needs for improved education and access to genetic counseling and testing for PD worldwide. © 2023 International Parkinson and Movement Disorder Society.

BACKGROUND: Patients with Restless Legs Syndrome (RLS) experience psychological distress and diminished quality of life. Antipsychotics and antidepressants are known to be linked to RLS. AIMS: This study aims to investigate the presence of RLS in psychiatric patients who receive antipsychotic and antidepressant drugs and to determine potential risk factors for its occurrence. METHODS: Two hundred patients who received antipsychotic and antidepressant drugs for more than 1 month were recruited from two tertiary psychiatric centers in Cairo, Egypt. One hundred apparently healthy volunteers were also included. All patients and controls were screened using the four-items questionnaire (Arabic version) for RLS. RLS severity was scored according to the validated Arabic version of International Restless Legs Syndrome Study Group rating scale (IRLS). Mimicking conditions were carefully investigated and excluded. RESULTS: Forty-one percent of the patients who receive antipsychotic and antidepressant drugs were found to have RLS. Family history, past history and smoking are potential risk factors. Trazodone and haloperidol were less associated with RLS. CONCLUSIONS: Although limited by its cross-sectional design, these findings suggest that patients who receive antipsychotic and antidepressant are susceptible to RLS. However, these results need to be replicated on a wider scale.

BACKGROUND: Further reports are required to describe the outcome of truncal dystonia treated by bilateral pallidal stimulation (globus pallidus interna deep brain stimulation [GPi-DBS]), owing to the small number of reports and clinical variability and complexity of truncal dystonia. Retrospectively, we report our experience of treating three patients with idiopathic generalized dystonia, with predominant mobile truncal dystonia by bilateral GPi-DBS. METHODS: Three patients with idiopathic generalized dystonia underwent bilateral GPi-DBS. One patient had adult-onset dystonia, while two patients had childhood-onset dystonia. All patients had predominant mobile truncal dystonia of mixed abnormal postures (camptocormia and lateral tilt), while one patient had also truncal twist. Patients were assessed pre- and post-GPi-DBS using the Burke-Fahn-Marsden Dystonia Rating Scale (BFMDRS) and Dystonia Disability Scale (DDS). RESULTS: The three patients showed marked improvement of global (94.78%, 92.4% and 80.95%) and truncal BFMDRS (all abnormal postures) (87.5%, 93.75% and 87.5%) and DDS (95.84% and 50%), using high amplitude monopolar settings, with a dramatic improvement of the mobile component. Improvement was persistent for 1.5, 3 and 6 years. CONCLUSION: Bilateral GPi-DBS improves markedly the mobile truncal dystonia and associated abnormal postures in patients with adult and childhood-onset idiopathic generalized dystonia. Improvement was persistent for up to 6 years.

Ataxia telangiectasia is a rare autosomal recessive multisystem disorder caused by mutations in the gene of ATM serine/threonine kinase. It is characterized by neurodegeneration, leading to severe ataxia, immunodeficiency, increased cancer susceptibility, and telangiectasia. Here, we discovered a co-segregation of two ATM gene variants with ataxia telangiectasia in an Egyptian family. While one of these variants (NM_000051.4(ATM_i001):p.(Val128*)) has previously been reported as pathogenic, the other one (NM_000051.4(ATM_i001):p.(Val1729Leu)) is regarded as a variant of uncertain significance. Our findings in this family provide additional evidence for causality of the second variant and argue that its status should be changed to pathogenic.

Childhood-onset movement disorders represent a heterogenous group of conditions. Given the complexity of these disorders, the transition of care from pediatric to adult medicine is an important consideration. We performed a scoping review of the literature on transitional care in chronic neurological disease, exploring key transitional issues and proposed transitional care models. Our aim was to describe the current knowledge and gaps about the transition process of young adults with chronic neurological disorders, paying special attention to childhood onset movement disorders. A total of 64 articles were included in the qualitative synthesis; 56 articles reported on transitional care issues, and 8 articles reported on transitional care models. Only 2 articles included patients with movement disorders. The following 4 main transitional issues were identified following synthesis of the available literature: (1) inadequate preparation for the transition process, (2) inappropriate and inconsistent transition practices, (3) inadequate adult services, and (4) heightened emotional response surrounding transition. Of the reported transitional care models, multidisciplinary ambulatory care was the most common approach. In studies evaluating patient-related outcomes, positive health, educational, and vocational outcomes were found. The available literature provides insights on issues that can arise during transition that should be addressed to improve patient and caregiver comfort and satisfaction with care. Further research is needed to evaluate how transitional care programs affect outcomes and their cost effectiveness. More studies are required to determine the needs and outcomes specific to patients with childhood onset movement disorders. © 2020 International Parkinson and Movement Disorder Society.

BACKGROUND: The growing burden of Parkinson's disease (PD) in Africa necessitates the identification of available therapies and services to improve patient care. OBJECTIVE: To investigate the availability, affordability, frequency of usage, and insurance coverage of PD therapies (pharmacological, surgical, physical, and speech therapies) and services including specialized clinics, specialists, and nurses across Africa. METHODS: A comprehensive web-based survey was constructed and distributed to neurologists/physicians with a special interest in PD across Africa. The survey instrument includes components that address availability, affordability, frequency of use, and insurance coverage of different therapies and services. RESULTS: Responses were received from 28 (of 43 contacted) countries. Levodopa-based oral preparations were always available in 13 countries (46.4%) with variable affordability and "partial or no" insurance coverage in 60% of countries. Bromocriptine was the most available (50%) and affordable ergot dopamine agonists (DA), whereas non-ergot DA was always available in only six countries (21.4%). Trihexyphenidyl was the most available and affordable anticholinergic drug (46.4%). Tricyclic antidepressants and selective serotonin reuptake inhibitors were available in most countries (89.3% and 85.7% respectively), with variable affordability. Quetiapine and clozapine were less available. Specialized clinics and nurses were available in 25% and 7.1% of countries surveyed, respectively. Other services were largely unavailable in the countries surveyed. CONCLUSION: PD-specific therapies and services are largely unavailable and unaffordable in most African countries. The data provide a platform for organizing strategies to initiate or scale up existing services and drive policies aimed at improving access to care and tailoring education programs in Africa. © 2021 International Parkinson and Movement Disorder Society.

BACKGROUND: Leukoaraiosis (LA) is a finding in the elderly, that might be asymptomatic or can impact their motor and cognitive functions. We studied the presence of LA in the MRI of patients with AIS and its impact on functional outcome at 3 months. METHODS: 500 consecutive patients diagnosed as AIS were enrolled. Medical history included pre-medication by antiplatelets or statins, and vascular risk factors were reported by history and laboratory investigations. Severity of stroke was assessed by NIHSS and stroke outcome was evaluated on discharge and at 3 months by modified Rankin scale (mRS). LA was diagnosed by MRI-FLAIR sequence and delineated from acute infarction by diffusion-weighted image. And accordingly, patients were divided into group A (absent LA) and group B (present LA). RESULTS: 460 patients completed the study, with 53% of patients on antiplatelet therapy and 11.7% on statins prior to stroke. The percentage of patients with LA was significantly more than those without LA. Patients with LA showed a significantly higher age, more frequent and longer duration of diabetes and hypertension, ischemic heart disease, previous stroke/TIA and antiplatelet intake. Microbleeds were more and mRS was worse in LA group. CONCLUSION: The presence of LA in the background MRI of AIS patients is accompanied by the presence of more risk factors, and unfavorable outcome. Pre-medication with antiplatelets did not prevent the incidence of a new stroke especially in LA group. This might necessitate the identification of some medication for secondary prevention in patients with small vessel disease.

BACKGROUND: The COVID-19 pandemic restricted usual healthcare management for movement-disorders patients, with a consequent upsurge in telemedicine to bridge the gap. OBJECTIVE: To assess global telemedicine usage in the context of the pandemic. METHODS: The Movement Disorder Society (MDS) Telemedicine Study Group surveyed telemedicine experts from 40 countries across all continents in March-April 2020. Four domains of telemedicine were assessed: legal regulations, reimbursement, clinical use, and barriers; comparing emerging responses to the pandemic versus the baseline scenario. RESULTS: All forms of telemedicine for movement disorders increased globally, irrespective of country income categorization, as an immediate response to the pandemic. This was aided by widespread availability of technology and updated government regulations. However, privacy concerns, lack of reimbursement, limited access, and lack of telemedicine training were barriers highlighted worldwide. CONCLUSIONS: Questions remain about the longevity and extent of changes in regulations and reimbursement regarding telemedicine in the aftermath of the pandemic. © 2020 International Parkinson and Movement Disorder Society.

BACKGROUND: Sexual dysfunction (SD) is a common, yet under-reported, non-motor symptom (NMS) of Parkinson's disease (PD). The present study investigated the sexual functions in PD male patients, its correlation with motor and other NMSs, and their impact on health-related quality of life (HRQoL). METHODS: The sexual functions of 40 PD male patients were assessed using the International Index of Erectile Function (IIEF) and compared to 25 healthy age-matched controls. Patients were evaluated using the NMS Scale (NMSS) and the Arabic version of the Parkinson's-Disease Questionnaire (PDQ-39). We compared the sexual functions of younger (≤ 55 years) and elder (> 55 years) males and tested the correlations between sexual functions and motor, other NMSs, and HRQoL. RESULTS: Seventy percent of PD male patients reported erectile dysfunction. They showed significantly worse total (p < 0.001) and subscores of IIEF, compared to healthy controls. The total IIEF was inversely correlated to age of patients (p = 0.013), age at onset (p = 0.043), total, cognitive/mood, gastrointestinal and urinary domains of NMSS, and the cognitive domain of PDQ-39 (p = 0.013). Age was the main predictor (ß = - 0.581, p = 0.006) of SD. Elder patients showed worse sexual functions, stronger correlations to other NMSs, and more impact on HRQoL than younger patients. CONCLUSION: Sexual functions are worse among PD male patients with age as the main predictor. SD was associated with worse cognitive/mood and urinary domains of NMSS and has a negative impact on the patients' HRQoL among elder males.

BACKGROUND: Egypt is a densely populated country with living habits and health care services that differ from urban to rural regions. We aimed to study how characteristics of stroke vary among these regions. METHODS: This is a cross-sectional observational study of ischemic stroke, thus hemorrhagic and venous strokes were excluded. A total of 1475 ischemic stroke patients were recruited for analysis from a tertiary hospital in Cairo representing urban area and from a secondary care hospital in Suhag representing rural region. RESULTS: Analysis was done for 1143 ischemic stroke patients from urban and 332 from rural area. Onset to door was shorter in urban. Urban patients showed an older age and higher prevalence of hypertension and diabetes (65.9%, 48.6% respectively), while rural patients were characterized by female preponderance (51.5%), more dyslipidemia, smoking 44.6%, stroke in young 20.5%, atrial fibrillation 23.8% % and recurrent stroke 44.3%. Rural cases showed a severer deficit at onset and poorer outcome. CONCLUSION: Vascular risk factors, stroke type, and presentation tend to differ in Egypt according to the geographic distribution whether urban or rural. Studying patterns of such difference may aid in planning specific targeted preventive and therapeutic strategies for stroke in urban and rural Egypt.

There is no definite biomarker for confirming the diagnosis of essential tremor (ET) or differentiating it from other diseases, particularly Parkinson's disease. The present study aimed to investigate the serum levels of the α-synuclein protein (α-syn) and its autoantibodies in patients with ET compared with healthy controls and its relation to motor and non-motor symptoms in patients with ET. Serum α-syn and its autoantibodies were measured in 32 patients with ET and 32 age- and sex-matched controls. Both groups were assessed using the non-motor symptoms scale, MoCA, Beck Depression Inventory, Hamilton Anxiety Rating Scale, and the Short Form 36 Health Survey Questionnaire. Tremor was assessed using the Fahn-Tolosa-Marin Tremor Rating Scale. The serum α-syn concentration in patients with ET was significantly lower than that in healthy controls (P<0.001), with a positive predictive value of 0.81 and a negative predictive value of 0.75, while the serum anti-a-syn autoantibody concentration was not significantly different between the two groups. There were no correlations between serum α-syn or its autoantibodies and patients' clinical characteristics. Furthermore, patients with ET had worse cognitive impairment, depression, anxiety, non-motor symptoms and quality of life. The serum α-syn concentration was lower in patients with ET than in controls, with favorable predictive values, suggesting that it could serve as a biomarker for ET diagnosis.
RESUMO
BACKGROUND: Post-stroke movement disorders (PSMD) encompass a wide array of presentations, which vary in mode of onset, phenomenology, response to treatment, and natural history. There are no evidence-based guidelines on the diagnosis and treatment of PSMD. OBJECTIVES: To survey current opinions and practices on the diagnosis and treatment of PSMD. METHODS: A survey was developed by the PSMD Study Group, commissioned by the International Parkinson's and Movement Disorders Society (MDS). The survey, distributed to all members, yielded a total of 529 responses, 395 (74.7%) of which came from clinicians with experience with PSMD. RESULTS: Parkinsonism (68%), hemiballismus/hemichorea (61%), tremor (58%), and dystonia (54%) were by far the most commonly endorsed presentation of PSMD, although this varied by region. Basal ganglia stroke (76% of responders), symptoms contralateral to stroke (75%), and a temporal relationship (59%) were considered important factors for the diagnosis of PSMD. Oral medication use depended on the phenomenology of the PSMD. Almost 50% of respondents considered deep brain stimulation and ablative surgeries as options for treatment. The lack of guidelines for the diagnosis and treatment was considered the most important gap to address. CONCLUSIONS: Regionally varying opinions and practices on PSMD highlight gaps in (and mistranslation of) epidemiologic and therapeutic knowledge. Multicenter registries and prospective community-based studies are needed for the creation of evidence-based guidelines to inform the diagnosis and treatment of patients with PSMD.

Objective: Pain is one of the most common non-motor symptoms in Parkinson's disease (PD), with variable characteristics among populations. This multicenter Egyptian study aimed to translate and validate the King's Parkinson's Disease Pain Scale (KPPS) and questionnaire (KPPQ) into Arabic versions and to investigate the pain characteristics in Egyptian people with PD (PWP). Methods: 192 PWP and 100 sex and age-matched controls were evaluated by KPPS-Arabic and KPPQ-Arabic. Both tools were assessed for test-retest reliability, floor or ceiling effects, construct validity and convert validity. PWP were assessed also by MDS-UPDRS, Hoehn and Yahr, NMSS, PD Questionnaire-39, and the Non-Motor Fluctuation Assessment (NoMoFA). Results: KPPS-Arabic and KPPQ-Arabic showed inter and intra-rater consistency and high validity, with an acceptable ceiling effect. 188 PWP (97.9%) reported at least 1 type of pain, (p<0.001). The severity and prevalence of KPPS-Arabic domains were significantly higher in all pain domains among PWP compared to controls (p < 0.001). Fluctuation-related and musculoskeletal pains were the most common (81.3% and 80.7%, respectively). In the PD group, the total and domains of KPPS-Arabic were significantly correlated to the MDS-UPDRS total, parts I, II, III, PIGD, axial, and H &Y scores, but not age or age of onset. Predictors of KPPS-Arabic included the total MDS-UPDRS, part III-Off, disease duration, total NMSS, and NoMoFA. Conclusion: The current multicentre study provided a validated Arabic versions of KPPS and KPPQ, with high reliability and validity, and demonstrated a high prevalence and severity of pain within Egyptian PWP and characterized its determinants.
RESUMO
BACKGROUND AND PURPOSE: Intracranial arterial steno-occlusive disease is prevalent among non-white populations. We explored whether a similar pattern exists in Egyptians and assessed its clinical-radiological associations. METHODS: Consecutive acute ischemic stroke patients were recruited for 6 months and had magnetic resonance imaging/magnetic resonance angiography of brain within 2 days of the event. Magnetic resonance angiography was analyzed for significant stenosis (>50%), flow gaps, and complete occlusions in the major intracranial arteries. RESULTS: A total of 143 patients completed the study (62.4 ± 12.6 years, 58.7% males). Magnetic resonance angiography showed symptomatic arterial stenosis in 27.3%, asymptomatic stenosis in 16.1%, and occlusions in 23.7% patients. Carotid duplex showed stenosis >70% in only 7.7% patients. Patients with intracranial arterial steno-occlusive disease had higher National Institutes of Health Stroke Score at admission (10.9 ± 7 versus 8 ± 5.6; P=0.01). CONCLUSIONS: Symptomatic and asymptomatic intracranial arterial steno-occlusive disease was prevalent in this Egyptian acute stroke sample. This might have important implications on stroke management in this population.
