Active clinical trials for "Parkinson Disease"

This is a non-drug study in patients with Parkinson's Disease (PD) and healthy volunteers to process and analyze their blood and optional cerebrospinal fluid (CSF) samples ex vivo, or outside of their body, to further develop researchers knowledge on LRRK2 biomarkers. Participants were enrolled either in Cohort A or in Cohort B. A blood sample was collected in each participant within a maximum of two study visits within 14 days, and an option to complete both visits on the same day.

Articulatory deficits are present in most speakers with dysarthria, which negatively impacts their speech intelligibility, yet little is known about the relationship between articulatory movement and speech intelligibility. This study will examine the relationship between articulation measures, both acoustic and kinematic, and their relationship to perceptual measures (i.e., speech intelligibility and articulation ratings) in 30 individuals with dysarthria secondary to Parkinson's disease and 30 neurologically healthy adults of the same age. The findings will have implications for behavioral management.

This study aims to characterize dynamic stability disorders in two conditions mainly affecting the elderly and with similar walking deficits: hydrocephalus at normal pressure and Parkinson's disease, to provide the most relevant monitoring criteria in usual care.

Transcranial magnetic stimulation (TMS) is a procedure that has been shown to improve pain in chronic sufferers. It is a well-tolerated procedure that can be performed on an outpatient basis. It uses a plastic covered coil that sends a magnetic pulse through the skull into the brain and by targeting particular areas in the brain it can be used to help modulate the perception of pain. The study intends to use this technique to treat such a disabling symptom in patients who suffer from Parkinson's Disease (PD). Initially the aim is to study this technique in 48 patients who are suffering from pain and have PD. These patients would require an EEG before and after the stimulation. The stimulation would be performed over ten sessions and the patients would be assessed by a clinician using well recognized clinical tools. It is anticipated that there will be a meaningful improvement in pain. It is also anticipated that TMS is a safe technique to use in patients with PD. The study will be used to help plan a future study that compares TMS with sham technique to prove whether TMS could be an option in the treatment of such a disabling condition.

The purpose of this research study is to establish if a novel high-speed yoga program which incorporates visual cues can make a positive change in the participant's ability to make decisions and move as measured by several cognitive, balance and functional tests. It has been shown that yoga can improve balance and movement in those diagnosed with Parkinson's disease.

The Investigators aim to identify speech and language markers that provide information on cognitive function and predict cognitive decline in Parkinson's disease. The Investigators will administer speech tasks and cognitive assessments to participants with Parkinson's disease and healthy controls. The Investigators will also explore the associations between genetic factors and speech and cognitive status in Parkinson's disease.

Rationale: Parkinson's disease patients with deep brain stimulation electrodes represent a unique opportunity to study the influence of basal ganglia on neurocognitive function. Intervention: Patients' deep brain stimulators will be turned off or on and the frequency will be changed to either theta or gamma. Objectives: To identify differences in higher cognitive functions with stimulation "on" and "off" and theta versus gamma frequency stimulation. Study population: 12 patients who had previously undergone bilateral STN deep brain stimulation implantation. Study methodology: Patients will undergo four sessions of neuropsychological testing (RNGT, verbal fluency, D-KEFS CWIT) at baseline, no stimulation, theta stimulation and gamma stimulation, in random order over one day. Study outcomes: Test results of RNGT, verbal fluency, D-KEFS CWIT. Follow-up: none Statistics: Test results will be analyzed using within-subjects statistical tests.

this pilot study aims to further explore the potential usage of Fecal microbiota transplantation in treating constipation and possibly also motor symptoms in Parkinson's disease (PD) patients, and to increase understanding of the potential relationship between the identities of intestinal microbial communities and PD.

Evaluate the use by the patient and his family and professional environment of a self-rehabilitation device with follow-up in tele-rehabilitation in people with Parkinson's disease taking into account the different actors within a health area (health professionals and paramedics in structure and in liberal).

The purpose of this study is to determine how using auditory cues of a metronome at various frequencies impacts the gait mechanics and balance in people with Parkinson's disease when walking over ground and on a treadmill. We will enroll 10 participants with a diagnosis of Parkinson's disease (Stages 2 or 3). All participants will complete 18 training sessions over 6 weeks and participate in pre- and post-testing of gait and balance.
