Parkinson's DiseaseFunctional Movement Disorders1 more

The purpose of this study is to investigate the clinical correlates of the effects of the COVID-19 pandemic on patients with Functional movement disorder (FMD) and Parkinson s Disease (PD). Primary objectives: To evaluate the change in neurological symptoms domain of the survey between pre and post-COVID 19 in FMD and PD patients. Secondary objectives: To evaluate the change in total score of the survey between pre and post COVID 19 in FMD and PD patients To evaluate the change in other symptom domains of the survey between pre and post COVID 19 in FMD and PD patients. Domains include: Mood/Energy, sleep, symptoms of abnormal movements related or unrelated to primary disease, physical health and exercise related change Exploratory objectives: To evaluate whether there is a modifying effect of disease group in the changes in total score or symptom domains To evaluate whether there is a relationship between disease severity and changes in total score or symptom domains To evaluate whether there is a correlation between changes across symptom domains To evaluate whether there is a correlation in raw score across symptom domains within each period Research Methods: Data will be solely collected through the use of online instruments via CiSTAR as a designed questionnaire. Questionnaire items A questionnaire aimed at determining the effects of the COVID 19 pandemic and subsequent isolation on functional state of patients with FMD and PD. The questionnaire items include: Items investigating Mood/Energy before and after COVID 19 out break Items investigating Sleep habits before and after COVID 19 out break Items investigating Neurological symptoms before and after COVID 19 out break Items investigating daily functioning before and after COVID 19 out break Items investigating Exercise habits before and after COVID 19 out break No questionnaire items will be actionable , which are items that would identify an imminent risk for participant safety requiring urgent and immediate medical or psychiatric

Diagnosis of Parkinson's Disease Using Diffusion Magnetic Resonance Imaging

Parkinson Disease

The hypothesis of the study is that the dopaminergic cell death located in the basal ganglia of the brain in patients with Parkinson's Disease can be detected by diffusion Magnetic Resonance Imaging, specifically by diffusion kurtosis imaging. The preliminary result was published in Radiology 2011. The current study proposed to investigate the following issues: validation of diagnostic sensitivity and specificity differential diagnosis capability between PD and PD+ syndrome prognosis capability In the first year, patients with Parkinson's disease will be recruited from the outpatient clinics of movement disorders in ChangGung memorial hospital Linkou, Taiwan. The diffusion parameters in basal ganglia will be compared with a group of healthy controls. In the second year, patients with progressive supranuclear palsy and patients with multiple system atrophy will be recruited for assessment of differential diagnosis. The patients with Parkinson's Disease will return for assessment of disease severity and in the third year, for the outcome evaluation.

Neurotransmitter Measurements Using (WINCS) During Deep Brain Stimulation Neurosurgery

Essential TremorParkinson's Disease1 more

In this study, the investigators will monitor extracellular neurotransmitter levels using a probe that is able to perform real time electrochemical detection during deep brain stimulation surgery. The overall question this study is designed to answer is: Are there neurotransmitters released during deep brain stimulation?

DBS Frequency on Swallowing Function in Parkinson's Disease

Parkinson's Disease

The stimulation frequency has been found to affect the axial symptoms of freezing of gait (FOG) and speech in advanced Parkinson's disease (PD) patients with subthalamic nucleus deep brain stimulation (STN DBS), with the traditionally high stimulation frequency of 130 Hz worsening while low frequency of 60 Hz improving these symptoms. The effect of stimulation frequency on another important axial symptom, swallowing dysfunction, has not been studied. The investigators hypothesize that stimulation frequency could have similar effect on swallowing function.

A Post Marketing Observational Study of Activities of Daily Living in Advanced Parkinson's Disease...

Parkinson's Disease

Patients with advanced Parkinson's Disease experience a range in the severity of their motor fluctuations. The rationale for this Post Marketing Observational Study is to demonstrate the benefits of Duodopa treatment on Parkinson's Disease patients entering the advanced stage of the disease whose motor fluctuations have become troublesome and complicate management with oral therapy. The aim of this post-marketing observational study is to assess the effect of Duodopa treatment on activities of daily living in advanced Parkinson's Disease participants characterised by either 2-4 hours of "off" time or 2 hours of non-troublesome or troublesome dyskinesia daily, supported by a Unified Parkinson's Disease Rating Scale Total Score in the best "on" state of at least 40 points at baseline.

Evaluation of Directional Stimulation During the Implantation of Deep Brain Stimulation (DBS) Leads...

Parkinson's DiseaseEssential Tremor

The purpose of this study is to provide proof-of-concept that directional stimulation, in an intraoperative setting, is perceivable in a subject and is different from omnidirectional stimulation. The tests will be performed using a dedicated DBS lead connected to external neurostimulator.

Imaging Biomarkers in Parkinson s Disease

Parkinson Disease

Background: - Parkinson s disease (PD) causes slow movement, stiffness, and tremor. It results from the loss of a brain chemical called dopamine. PD gets worse over time, but researchers do not fully understand why the brain cells that produce dopamine stop working or die in people with PD. This study will use different ways of imaging the brain and brain chemicals to look at PD. It will compare brain imaging in people who definitely have PD to people who might have PD and to people without signs of PD. It will provide more information how the brain in people with PD changes over time. Objectives: - To understand the changes that occur in the brains of people with Parkinson s disease. Eligibility: Individuals at least 18 years of age who have definite or possible Parkinson s disease. Healthy volunteers at least 18 years of age. Design: Participants will have a screening visit with a physical exam and medical history. Participants will visit the National Institutes of Health Clinical Center every 18 month or 3 years for up to 9 years. There will be up to 6 total visits. Most visits will last 5 to 6 hours a day for 1 to 3 days. Some or all of the following tests will be performed at each visit: Magnetic resonance imaging to take pictures of the brain. Some of these tests will be done at rest. Others will require participants to perform an activity during the scan. Medication withdrawal for 12 hours overnight for people taking PD medications. This may be done before some scans. Participants who feel unwell when they stop taking medications will be allowed to start taking them again. Participants will continue with the follow up visits until the end of the study.
