Active clinical trials for "Parkinson Disease"

When a patient with Parkinson's disease (PD) is initially treated with L-dopa or dopamine agonists, the symptoms of PD improve or disappear. After several years of taking L dopa or dopamine agonists, patients notice that their PD medications wear off sooner than when they first started taking them. This "wearing off" is characterized by the return of symptoms (i.e., tremor, slowness, and rigidity) and may occur over the course of a few minutes to an hour. When a patient's PD symptoms have returned, the patient is said to be in the "off" state. When the patient takes another dose of medication, and his/her PD symptoms improve or resolve, the patient is said to be in the "on" state. Antagonism of adenosine Type 2a receptors (A2a) may provide relief of PD symptoms. This trial will test the hypothesis that A2a receptor antagonism can lead to improvement in the function of PD participants taking a stable dose of L-dopa, as measured by a reduction in "off" time.

By creating a neurogenebank from Parkinson's disease patients' blood donations we will ultimately be able to define genes for Parkinson's disease and other neurological conditions.

Determine if a novel levodopa/carbidopa formulation results in a better clinical response on Parkinson's Disease patients compared to the reference formulation of levodopa/carbidopa in terms of motor complications, onset of action and response duration.

The purpose of this study is to show Rotigotine dose response at four doses of Rotigotine used with L-dopa in treating advanced stage Parkinson's disease.

The aim of the study is to train patients with Parkinson's Disease to increase activity in a brain area that is involved in the control of motor functions with the use of a technique called real-time fMRI neurofeedback (NF) along with regular physical exercise. This will be a randomised and controlled clinical trial to evaluate the benefits of a novel treatment. The investigators expect NF training along with physical exercise practise to better improve motor functions compared to physical exercise alone.

The investigators conducted an intervention based in proprioceptive exercises and balance tasks. The investigators also carried out a brief intervention in manual dexterity. The study hypothesis is that a brief intervention in upper extremities and a exercise program can increase functionality in Parkinson.

Primary aim is to conduct a pilot trial to determine: The feasibility and efficiency of randomisation procedures and study design If recruitment rates are sufficient to adequately power a larger trial The secondary aim is to determine the efficiency of set dancing in comparison to a control for people with Patkinson's disease.

Single-centre, open-label, fixed-sequence design consisting of 2 periods separated by a washout period of at least 14 days.

This randomized, controlled trial (RCT) evaluates the benefits of expressive compared to neutral writing in individuals with Parkinson's Disease and their support persons. Participants will be randomly assigned to complete three, 20 minute sessions of expressive or neutral writing. Participants will complete evaluation of outcomes at baseline, immediate post, 4 month and 10 month follow ups to establish if benefits remain over time. Impact of these therapies on thinking abilities, physical health, and patient and support person ratings of thinking skills, mood and quality of life will be evaluated. Expressive writing is hypothesized to result in greater improvements and/or stability of function on neuropsychological tests of attention, working memory, learning, and memory skills compared to the neutral writing condition. Results from this study will determine whether brief writing exercises are easily used by and beneficial for individuals with Parkinson's Disease and their support persons. If positive benefit is observed, information from this study will be used to further optimize these therapies for larger trials designed to evaluate the value of the therapies for individuals with Parkinson's Disease and their support persons.

Computer-Based Cognitive Training for Individuals with Parkinson's Disease" is a 3-arm randomized controlled trial (RCT) comparing Brain Fitness, InSight, and an active control (AC) training program to evaluate the feasibility of empirically supported computer-based cognitive training programs (CCTPs) for patients diagnosed with Parkinson's disease (PD) with Mild Cognitive Impairment (MCI). This pilot study aims to address the need for increased interventions to target non-motor symptoms associated with PD.
