Active clinical trials for "Parkinson Disease"

48 PD patients (age 35-75y; H&Y 1-3) testing positive in a stool PD-dysbiosis test will be randomized in a 2:1 ratio to receive either donor FMT or their own stool through intracaecal infusion. The main outcome measure will be the sum of MDS-UPDRS I-III at 6 months to cover motor and non-motor symptom changes. A wide array of secondary clinical outcome measures will be assessed longitudinally and a large array of measurements, biospecimens (stool, urine, blood, colonic biopsies), and imaging data will be collected for further analysis at baseline, 1, 6, and 12 months.

This study aims to assess the therapeutic role of rTMS on parkinson's patients with cognitive impairment. Patients diagnosed with Parkinson's Disease and cognitive impairment will be recruited. All patients will be admitted and will be allocated randomly into two groups one of which will receive real sessions of high frequency rTMS for each hemisphere for 10 consecutive sessions totally over period of 10 days with repeated booster sessions every month during the period of follow up. The other will receive sham sessions.

Vanderbilt University Medical Center is one of the largest-volume DBS centers in the country. From 2007 through October 2017, 265 Parkinson's disease (PD) patients underwent deep brain stimulation (DBS), 168 of those implanted in subthalamic nucleus (STN) and 97 in globus pallidus interna (GPi). Pre-operatively, each patient is extensively evaluated with a battery of validated motor, cognitive, and mood instruments. This information is stored in RedCAP, a secure online database platform. In an attempt to capture longitudinal outcomes in this population of interest, we will recruit all PD patients two years or more status post DBS who are receiving regular care at Vanderbilt University Medical Center. Study participants will undergo a condensed evaluation of motor function (Unified Parkinson's Disease Rating Scale Part III), cognitive performance (Mini-Mental Status Examination), mood (Beck Depression Inventory), and quality of life (Parkinson's Disease Questionnaire-39). These results will be compared to baseline measures performed pre-operatively, allowing for assessment of interval change. STN and GPi DBS patients will be analyzed separately.

the purpose of the study was to the compare pharmacokinetic profile of BIA 6-512 in healthy elderly subjects versus healthy young subjects after single and repeated oral administration of 200 mg BIA 6-512.

This will be a double-blind, randomised, placebo-controlled parallel-arm phase II proof of concept in subjects with PD treated with a stable dose of levodopa who are experiencing both end-of-dose wearing off and Levodopa-Induced Dyskinesia (LID)

The purpose of this study is to investigate whether speed-dependent measures of gait can be identified in patients with neurological conditions that affect gait, particularly in subjects with parkinsonian disorders.

Purpose: Rest tremor in Parkinson's disease is notoriously difficult to treat through pharmacological measures, currently only predictably attenuated by the invasive deep brain stimulation surgery. The investigators hope to find some predictable and clinically meaningful attenuation of tremor with targeted use of onabotulinum toxin on muscles involved in creating the tremor. Participants: 16 subjects who meet United Kingdom (UK) brain bank criteria for Parkinson's disease with medically refractory rest tremor of at least 3 cm amplitude. Procedures (methods): Subjects will be blinded to receive either sham saline injection versus onabotulinum toxin injections directed to muscle groups felt to be clinically involved in causing the oscillatory movement of the tremor. Assessment of tremor severity and functional improvement from baseline after injection will occur within group (i.e. each subject will serve as their own control). Hypotheses: 1. (A) Onabotulinumtoxin A significantly attenuates the amplitude of medically-refractory rest tremor of the upper limb in Parkinson's patients as compared to sham injections; as measured by reduction in the Movement Disorders Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) tremor subscore. 1. (B) Onabotulinumtoxin A significantly improves the limb function of Parkinson's patients with medically-refractory rest tremor of the upper limb as compared to sham injections; as measured by an increase in Action Research Arm Test (ARAT) scores.

A pilot study with the "10cubes" for small and precise movements and training in the virtual environment will be carried out. We will recruit at least 20 persons with Parkinson's disease to participate in the study. Such activities can increase participation, slow down the progress of the disease and contribute to the functional improvements of the hand that lead to the increased quality of life. The movement of the hand will be assessed with a small 3D camera, also suitable for the estimation of kinematic parameters. Participants will be randomized into 2 groups; one group using an LCD screen and the other using 3D goggles (Oculus Rift CV1) enabling them to carry out the task in virtual environment. Both groups will take 10 training sessions within 2 weeks. Their task will be collecting 10 virtual cubes one-by-one and putting them in the virtual treasure box. Clinical tests (Box and Blocks Test and motor part of the UPDRS) will be carried out in the clinical settings prior and after the training sessions. We hypothesise that the different feedback equipment may provide different results.
