Fibrotic valvular heart diseases are known as rare complications of long-time therapy of Parkinson's disease with ergot-derivatives including some ergot-dopamine agonists. The aim of this study is to assess the incidence of valvular heart disease, which may be an ergot-drug agonists side-effect or an overall complication of all dopamine agonists. Incidence, prevalence and addiction of dose or intake duration are not known so far. The reversibility of the changes is unknown too. To answer these questions the present study is designed as a cross sectional study followed by a 2 year follow-up prospective cohort study.
The purpose of this study is to determine the safety of using a modified virus to transfer a gene called GAD into a region of the brain called the subthalamic nucleus in patients with advanced Parkinson's disease. The overall goal of this approach is to ultimately normalize the flow of information in several brain regions responsible for movement, to ultimately improve function in patients with this disorder. The current study is primarily designed to evaluate the safety of this approach, but patients are also being monitored for possible signs of effectiveness as well.
Patients with Parkinson's disease (PD) suffer from motor fluctuations and levodopa induced dyskinesia. The prupose of this study is to evaluate the effect of an automatic system to assess the motor state of PD patients in real daily life. Movements and postures are assessed using 6 accelerometers attached to the the most affected wrist, trunk, both upper legs and both upper arms. Patients wear the system for two days and keep an own diary of their motor state
This study was designed to evaluate the symptomatic effects of Coenzyme Q10 nanodispersed solution in middle-stage Parkinson's disease (PD) patients (Hoehn&Yahr II to III). The treatment phase includes three months period of 300 mg Coenzyme Q10 per day or placebo. The primary outcome measure was the combined Unified Parkinson's Disease Rating Scale (UPDRS) Part II and III. The hypothesis of this study was that Coenzyme Q10 improves the energy status of the diseased dopaminergic neuronal cell type and thus producing more dopamine leading to an improvement of parkinsonian symptoms in PD patients.
We will evaluate the effect of deep brain stimulation on the depression and quality of life in Parkinson’s disease. We aim to compare depression pre-operatively and post-operatively in Parkinson’s patients with deep brain stimulation to Parkinson’s patients evaluated and approved for deep brain stimulation but who did not complete surgery. We will also compare quality of life measures between patients with and without deep brain stimulation.
Parkinson's disease is a frequent neurodegenerative disorder. Genetic forms of the disease have been recently identified. The monogenic form due to parkin mutation is responsible for many familial cases and sporadic forms. However, the relationship between the mutation and the genotype of patients is not fully established. The aim of this study is to compare clinical, metabolic and neuropsychological characteristics obtained in patients with parkin mutation with those of patients without parkin mutation.
This is a randomized, double-blind, two treatment, two group, parallel group study. Subjects will be randomized to one of two treatment groups (E2007 or Placebo) in a 3 to 1 ratio and receive treatment for a total of ten weeks (Days 1 to 70).
To determine the effects of the NMDA antagonist, CP-101,606, in subjects with Parkinson's Disease
The study is designed to measure the difference of dopamine turnover rate measured by Fluoro-Dopa-PET in the putamen between patients with Parkinson's disease treated with cabergoline and levodopa for 3 months. The study protocol includes an initial Fluoro-Dopa-PET scan before treatment and after three months double-blind treatment with cabergoline or levodopa. The hypothesis for this study is that the dopamine turnover rate is a more sensitive marker for the early diagnosis of Parkinson's disease compared to the standard Fluoro-Dopa-PET measuring only the Fluoro-Dopa uptake into the striatum. For the interventional part of the study, the hypothesis is that levodopa has larger effects on striatal dopamine turnover compared to dopamine agonists by providing more dopamine precursor. Enhancement of compensatory mechanisms for dopamine loss in early PD such as increased dopamine turnover could have several beneficial implications such as improvement or prolongation of symptomatic treatment responses, but might also produce therapeutic problems such as the development of levodopa-induced motor complications.
