Active clinical trials for "Parkinsonian Disorders"

This is a double-blind, placebo-controlled, Phase IV trial , comparing HMS 90® versus placebo (soy protein) as add-on (adjuvant) therapy in subjects with idiopathic Parkinson's Disease. The principal objective is to evaluate the changes in biomarkers of oxidative stress and,plasma amino acids, as well as improvement of clinical symptoms and brain function

mPDia is a software that has been pre-learned based on a neurodegenerative parkinsonism diagnosis model using Nigrosome 1 MRI images, and clinical decision support system for diagnosing neurodegenerative parkinsonism by automatically analyzing Nigrosome 1 MRI images by assisting the medical team. The specific aims of this study are to evaluate efficacy of mPDia for neurodegenerative Parkinsonism compared to the sensitivity and specificity levels of 18F FP-CIT PET/CT which is currently used to diagnose neurodegenerative parkinsonism.

Drug therapy of atypical parkinsonism is generally considered either ineffective or minimal 1. Therefore, there is an urgent need to find alternative therapies to treat atypical parkinsonian disorders. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive tool that modulates cortical excitability with minimal discomfort and holds therapeutic promise in treating neurological and psychiatric disorders. The basal ganglia-thalamocortical circuits that are affected in Progressive Supranuclear Palsy (PSP) and Corticocbasal Ganglionic Degeneration (CBGD) are likely structurally and functionally segregated. The 'motor' circuit is implicated in parkinsonian akinesia and hypokinesia; a 'prefrontal' circuit is implicated in working memory and mood regulation, and linked with non-motor symptoms such as depression and apathy. In this proposal, we characterize motor and prefrontal network dysfunction in PSP and CBGD patients, and propose that high-frequency and low-frequency rTMS directed over separate motor and prefrontal cortical targets of each network may show specific and selective beneficial effects on motor vs. cognitive function in PSP and CBGD patients, respectively. Quantitative motor outcome measures include timed finger tapping tasks. Quantitative cognitive outcome measures comprise a visual analogue scale (VAS). If successful, this pilot study will provide proof of principle data to suggest potential benefits for rTMS in PSP/CBGD patients, and provide sufficient data and experience to support future PSP/CBGD studies that include the use of rTMS to investigate the pathophysiology of motor and non-motor features of PSP and CBGD patients.

Dystonia is a disabling symptom affecting both patients with idiopathic Parkinson's disease (PD) and atypical parkinsonism (AP). Botulinum toxinum (BoNT), by blocking muscle contraction, is a possible treatment for focal dystonia. The benefit of BoNT treatment has been proven in some focal dystonia associated with PD or AP. The investigators aim to give an overview of the efficacy of BoNT in a variety of focal dystonia in a large cohort of parkinsonian patients.

Background: - Parkinson s disease is a disease of the nervous system that affects movement. People usually get it in their 70s or 80s. Early onset Parkinson s disease (EOPD) begins before the age of 50. Researchers think EOPD may be caused by a mutation in a gene. They want to study the genetic causes so they can find therapies for this disease. Objective: - To better understand the genetic causes of EOPD. Eligibility: Adults ages 18 80 with a history of EOPD. Their family members, who do not have Parkinson s disease, can join as controls. Healthy volunteers ages 18 80. Design: Participants with EOPD and their relatives will be screened with a review of medical records. Healthy volunteers will have medical history, physical exam, and blood drawn. Relatives may send blood samples to NIH to test for mutations in genes that are linked to Parkinson s disease. They may have a physical exam. Participants may be asked to return to clinic for another visit that can last up to 2 hours. During this visit, participants will have blood taken from a vein in the arm via a needle stick. Participants may give a sample of their skin. The skin on the arm or leg will be numbed and a small skin punch biopsy will be taken with a special needle. Some cells from the blood or skin sample may be grown in a lab to establish cell lines. The cells may also potentially be genetically modified to make stem cells. Researchers may perform genetic analysis on the samples to compare them to EOPD patient samples.

The Cognitive Neuroscience Section of the National Institute of Neurological Disorders and Stroke proposes to continue its cross-sectional and longitudinal studies of cerebral metabolism in frontal lobe dementias and atypical basal ganglia disorders. These studies include repeated assessments of neuropsychological and brain anatomical and metabolic function in subjects with these important and possibly related brain disorders.

This observational and experimental study seeks to establish a Smart Device System (SDS) to monitor high-resolution handtremor-based data using Smartphones, SmartWatches and Tablets. By doing this, movement data will be analyzed in depth with advanced statistical and Deep-Learning algorithms to identify new clinical phenotypical characteristics Parkinson's Disease and Essential Tremor.

Diagnosing Parkinson's disease (PD) depends on the clinical history of the patient and the patient's response to specific treatments such as levodopa. Unfortunately, a definitive diagnosis of PD is still limited to post-mortem evaluation of brain tissues. Furthermore, diagnosis of idiopathic PD is even more challenging because symptoms of PD overlap with symptoms of other conditions such as essential tremor (ET) or Parkinsonian syndromes (PSs) such as progressive supranuclear palsy (PSP), multiple system atrophy (MSA), corticobasal degeneration (CBD), or vascular Parkinsonism (VaP). Based on the principle that PD and PSs affect brain areas involved in eye movement control, this trial will utilize a platform that records complex eye movements and use a proprietary algorithm to characterize PSs. Preliminary data demonstrate that by monitoring oculomotor alterations, the process can assign PD-specific oculomotor patterns, which have the potential to serve as a diagnostic tool for PD. This study will evaluate capabilities of the process and its ability to differentiate PD from other PSs with statistical significance. The specific aims of this proposal are: To optimize the detection and analysis algorithms, and then to evaluate the process against neurological diagnoses of PD patients in a clinical study.

This study is designed to determine if magnetic resonance imaging (MRI) measures can be used to diagnose and monitor the progression of Parkinson's disease (PD) while distinguishing between PD and parkinsonisms [conditions that are PD look-a-like diseases such as progressive supranuclear palsy (PSP) or multiple system atrophy (MSA)] when combined with changes in certain proteins in body fluids that are related to iron (Fe).
