Active clinical trials for "Parkinson Disease"

The purpose of this study is to investigate the pharmacokinetic profile of ropinirole PR after single and multiple doses of the PR-formulation. It will also investigate the safety and tolerability of ropinirole PR after single and multiple doses of PR-formulation.

The investigators are interested in determining if the investigators are able to detect changes in brain chemistry using Magnetic Resonance Spectroscopy (MRS) in individuals with Parkinson's disease (PD), those with Gaucher's disease (GD), and those without neurological disorders (healthy controls) when they are given the antioxidant N-acetylcysteine (NAC). This study will combine information from a medical history, a physical examination and disease rating scales with results obtained using MRS brain scans and pharmacokinetic studies from blood samples. This research will require 1 visit that will require about 4 to 5 hours of time. During this study, participants will provide their medical history, be examined and undergo a rating scale for about one hour; the brain scan and pharmacokinetic studies will require 1.5-2 hours of time; in total the study will take about 4-5 hours.

The primary objective of the study is to evaluate the safety and tolerability of ADX48621 in Parkinson's disease patients following four weeks of dosing. The secondary objectives of the study include the evaluation of the efficacy of ADX48621 compared with placebo in reducing levodopa induced dyskinesia in patients with Parkinson's; the evaluation of the effect of ADX48621 on symptoms of Parkinson's disease and patient ability to function, and the evaluation of the effect of coadministration of ADX48621 on L-dopa efficacy.

The purpose of this study is to determine the relationship between attention and quality of life and how rivastigmine and atomoxetine alter attention in non-demented persons with Parkinson's disease (PD).

The purpose of this study is to determine if varenicline is effective in improving gait and balance impairment in patients with Parkinson disease.

People with disease (PD) tend to walk with short steps, decreased velocity, and increased stride time variability. Short steps and increased variability are related to greater fall risk. In addition, concurrent performance of a cognitive task (dual-task (DT)) has marked effects on gait in people with PD which is considered to reflect an impaired automaticity of gait. Objective: To investigate short and long term effects of high-volume walking with visual spatial cues (VSC) on gait variables, automaticity, and functional mobility, in people with Parkinson´s Disease (PD), compared with walking without VSC.

This study will assess the efficacy and safety of AFQ056 in patients that have Parkinson's Disease L-dopa Induced Dyskinesias (PD-LID)

This is a extended long-term safety study in Parkinson's disease patients who have motor response complications on levodopa therapy and completed 12 weeks administrations of KW-6500 in 6500-004 study. The safety and efficacy of long-term subcutaneous self-injections of KW-6500 are evaluated.

The use of low level electrical stimulation when applied over the head, also called transcranial direct current stimulation (tDCS), is being tested by several groups of researchers to see if tDCS can improve movements of persons with damage to the brain. The safety and potential benefits of tDCS to children or adults patients who are paralyzed because of brain damage are reported in the medical literature. In addition, some patients with Parkinson's disease (PD) experience improvement in memory and report better use of the hand after tDCS. The treatment requires putting electrodes (pads) over the head and sending very small amount of electrical current that the patient may feel as "little tingling". Application of tDCS takes 20 min. In this study we wish to test if tDCS application can improve stepping and walking ability of subjects with PD and if the improvement is the same as when walking on treadmill. We plan to test the subject's ability to step when pulled by a laboratory testing system and also test his/her walking ability. There will be 3 sessions 7 days apart. In the first session the subject will be tested then treated for 20 min with tDCS and then tested again. In the second session the subject will be tested then walk on a treadmill for 20 min then tested again. In the third session the subject will be tested then walk on the treadmill for 20 min while receiving also tDCS and tested one last time at the end of the session. Each session will take between 2 and 3 hours.

To evaluate the efficacy of a fixed dose of Azilect® (1 mg/day) vs placebo as assessed by the change from baseline in mean total daily OFF time during 18 weeks of treatment in levodopa-treated Parkinson's Disease (PD) patients with motor fluctuations in Korea.
