Active clinical trials for "Parkinson Disease"

This study is intended to look at the safety and efficacy of the use of autologous bone marrow derived stem cell transplant in patients with advanced Parkinson's disease.

The purpose of this study is to determine whether treatment of H. pylori (an infection of the stomach) improves treatment effectiveness in patients with Parkinson's disease and motor fluctuations.

This is an open, randomised, active-controlled, 2-period crossover study comparing the effect of single doses of Stalevo 200 and Sinemet on striatal (putamenal and caudate) 11C-raclopride BP in PD patients with wearing-off symptoms. The study consists of 4 visits: a screening visit (visit 1), 2 treatment periods (period 1=visit 2, period 2=visit 3) separated by a minimum wash-out period of at least 3 days, and an end-of-study visit (visit 4). Subjects will be randomly allocated to start the period 1 with a single dose of Stalevo 200 or Sinemet. After the wash-out the study drug on period 2 will be administered according to a crossover design.

Retrospective review of records in the Emory Movement Disorders clinic suggests vitamin D deficiency occurs in over 80% of patients with Parkinson's Disease (PD), much more frequently than in internal medicine clinics. Laboratory studies have suggested vitamin D could play a role in the development of PD. In addition, low vitamin D levels have been associated with slower walking speeds, worse memory and thinking, and depression.

Patients with Parkinson's disease represent a significant proportion of VA elderly patients. Sleep disturbances and caregiver burnout association with this condition represent a significant problem. In this study, the investigators propose to perform an evaluation of a fixed doe of ramelteon on sleep in VA outpatients diagnosed with Parkinson's disease. The hypothesis to be examined is that ramelteon will improve the quality of sleep in patients with Parkinson's disease while indirectly improving the quality of life for the patients and caregivers. The investigators further hypothesize that these changes will occur through restructuring and normalization of the sleep architecture.

The goal of this study is to increase magnetic resonance image quality in patients suffering from Parkinson's disease. The main question it aims to answer is: can super-resolution improve clinical magnetic resonance image quality to benefit deep brain stimulation for Parkinson's disease? Participants will receive an additional high-quality MRI scan.

The presence of a damage to the central and / or peripheral nervous system resulting from diseases of a different nature (such as, Multiple Sclerosis, Parkinson's disease, dementia, head trauma, stroke, epilepsy or other neurological syndromes) is commonly cause of both physical than mental disability. The evaluation of certain domains may be more difficult so, specific assessment tools are necessary to analyze them.

The goal of this project is to provide comprehensive longitudinal assessments of a cohort of PD patients before, during, and after DBS surgery, including neurological, neurophysiological, and neuropsychological data.

The purpose of the study is to learn about the impact of exercise on fatigue, anxiety, and depression in Parkinson's disease. It is well established that exercise improves the motor symptoms of Parkinson's disease. However, it is not clear which types of exercise are most beneficial for specific non-motor symptoms.

Subthalamic nucleus deep brain stimulation (STN-DBS) has become a choice treatment for fluctuating Parkinson's disease (PD) patients, inducing remarkable improvement in motor symptoms. However, as PD is a complex neuropsychiatric disease, it has been hypothesized that in some patients, non-motor features, i.e. dysfunctional expectations for the result of neurosurgery, could interfere with postoperative result of DBS, even in case of motor improvement. Recent literature highlights the necessity to take these preoperative expectations into account, but to our knowledge, no specific scale investigating these cognitions in this PD-specific condition is available. So, the investigators developped the DBS-PS, a self-scale constructed to measure preoperative expectations for DBS, with 11 questions and visuo-analogical responses (1 to 10), theorically divided in three domains investigating the expectations concerning symptoms of PD, postoperative social-life and leisures, and postoperative familial and marital sphere. The investigators would like to validate this new-developped scale in the preoperative subthalamic nucleus deep brain stimulation population through patients recruited in the Predistim study, whereas the investigators did not recruite sufficiently patients through the PsyParkinson study, the one in which the DBS-PS scale was developed. The DBS-PS constitutes an interesting basis for the consideration of these cognitive and affective factors in preoperative PD patients.
