Filter by:The purpose of the study is to develop, deliver, and test an online Alexander-based training program for people with Parkinson's disease and their care partners.
The purpose of this investigation is to determine the optimal DRT/VIM target location and its safety margins based on MR-SISET imaging features by comparing with postoperative lesions and clinical outcomes in patients with tremor who will undergo the MRgFUS tremor therapy.
Converging evidence from the literature suggests that digestive inflammation may play a role in the development of Parkinson's disease (PD). The investigators showed in the laboratory in a pilot study that PD patients have digestive inflammation and that the level of inflammation was inversely related to the length of the disease course. This digestive inflammation could be at the origin of an increased intestinal permeability in a subpopulation of parkinsonian patients, cause or consequence of modifications of the intestinal microbiota, thus offering a potential portal of entry for a pathogen according to Braak's theory. To opponents of this theory, it could also reflect the spread of inflammation from the Central nervous System to the Enteral Nervous System (ENS), via the brain-gut axis. Investigators' hypothesis is that digestive inflammation occurs very early in Parkinson's disease and that it is associated with hyperpermeability of the intestinal epithelial barrier and a change in the intestinal microbiota composition. The investigators propose to study the inflammation markers in the ENS of patients with a pre-motor form of PD (idiopathic Rapid Eye Movement (REM) sleep behavior disorder, n = 20), early-stage PD (<5 years, without dopatherapy, n = 20), more advanced PD (> 5 years, n = 20) and control subjects (n = 20), on colonic biopsies taken during a rectosigmoidoscopy or a coloscopy. Intestinal permeability will be measured by ex-vivo techniques (in a Ussing chamber), the composition of the microbiota will be established by sequencing 16s RNA and the lesional load of phosphorylated alpha-synuclein will be evaluated by immunohistochemistry. All of these parameters will be correlated with clinical data on the severity of PD: duration of development, age, total Unified Parkinson's Disease Rating Scale (UPDRS) motor score and axial sub-score, cognitive tests (Montreal Cognitive Assessment, MoCA), existence of a probable idiopathic REM sleep behavior disorder (REM Sleep Behavior Disorder Screening Questionnaire RBDSQ), olfactory tests, complaint of dysautonomia (SCales for Outcomes in Parkinson's disease - autonomic dysfunction, SCOPA-Aut). The analysis of inflammation markers, the intestinal barrier and the microbiota could be a first step making it possible to formulate physiopathological hypotheses on the development of PD, to propose predictive biomarkers of the disease and its severity and to design early interventions in the hope of modifying the evolutionary course of the pathological process.
The primary purpose of the study is to evaluate the safety and tolerability of single ascending doses of UCB7853 in healthy male study participants and to evaluate the safety and tolerability of multiple ascending doses of UCB7853 administered in study participants with Parkinson's Disease (PD)
This trial is expected to recruit patients with primary Parkinson's disease and give them four consecutive weeks of aerobic exercise to observe its effect on Parkinson's disease and explore its mechanism
Nearly 90% of people with Parkinson's disease have speech and voice disorders that negatively impact their ability to communicate effectively in daily life. This study will test the hypothesis that a combined speech and exercise intervention will improve speech intelligibility in people with Parkinson's disease and speech impairment. This approach would offer an affordable way to continue to both instruct and encourage training by Veterans virtually indefinitely through the remote access technology. These findings may help VA clinicians provide optimal care for the many Veterans with Parkinson's disease and speech impairment.
The aim of this project is to measure behavioural disorders in Parkinson's disease (PD) patients in a more objective way, in order to facilitate the detection of those symptoms and improve the treatment of non-motor symptoms in Parkinson's disease.
The purpose of this study is to Evaluate the Safety, Tolerability and Pharmacokinetics of Four Formulations of LY03009 in Healthy Volunteers.
Background: The ketogenic diet uses fats as a person's major energy source rather than carbohydrates. There is increasing interest in using this diet to treat neurodegenerative disorders like Parkinson's disease. Researchers want to learn more about the ketogenic diet before recommending this diet in clinical practice. Objective: To study the effects of a ketogenic diet for someone with PD. Eligibility: People over age 50 with mild to moderate PD. Design: Participants will be screened with surveys and a 10-foot walking test. They will have a medical history, physical exam, and blood test. Participants will be contacted twice in a 1-week period to discuss what they ate over the last 24 hours. They will log data about their daily exercise and activities using an online fitness tracking app. Participants will stay at NIH Clinical Center for 1 week. They will be put into 1 of 2 groups. One group will follow a ketogenic diet and take MCT oil. The other group will follow a low-fat diet. Their body measurements will be taken. They will meet with a physical therapist and nutritionist. Participants will have daily respiratory and glucose monitoring. They will have cognitive tests and complete surveys. They will have walking, motor function, and reaction time/finger tapping tests. They will have heart and nerve function tests. They will have electrocardiograms and electroencephalograms. Blood will be taken twice daily. Participants will follow the ketogenic diet at home for 2 weeks. They will log their activities using the fitness tracking app. Then they will have a follow-up visit at NIH. Participation in the trial will last for 4 weeks.
The primary objective of the study is to determine if subthalamic nucleus (STN) deep brain stimulation (DBS) using the Vercise directional leads improves neuropsychiatric state and neuropsychiatric fluctuations 12 months after surgery in a large consecutive series of STN-DBS Parkinson's disease (PD) patients.
