Active clinical trials for "Parkinson Disease"

Study to obtain information about the co-operation of the different physician-colleagues in the treatment of patients with Parkinson's disease, both in private practices and clinics and about the primary treatment strategies in the pharmacotherapy of Parkinson's disease and to collect data on the tolerability of Sifrol® in ambulatory patients suffering from Parkinson's disease under routing conditions

Parkinson's Disease (PD) is a movement disorder causing either uncontrolled movement, slowness of movement, slowness of initiation of movement or rigidity of muscles. Deep Brain Stimulation (DBS) is the FDA-approved method for patients who no longer get effective treatment from the best available medication. The location in the brain where the electrode is placed during DBS surgery for PD is called the Subthalamic Nucleus or STN. This study aims to investigate another location in the brain, the Substantia nigra pars reticulata or SNr. The SNr is also known to be involved in motor control of muscles and may be involved in the process by which the initiation of movement occurs.

Non-Ergot Dopamine agonists are meanwhile the drugs of first-choice in the treatment of Parkinson's disease. The receptor profile of the non-ergot dopamine-agonist piribedil is unique. In addition to agonistic effects on dopaminergic D2- and D3-receptors piribedil has adrenergic alpha-2A- and alpha-2C-receptors antagonisic properties. There is evidence from the literature that the antagonistic properties of piribedil are correlated with an improvement of cognitive function and vigilance parameters in parkinson's disease. The aim of the present non-interventional study is to investigate the safety and efficacy of piribedil during long-term therapy of patients with M. Parkinson under consideration of cognitive functions and quality of life.

Parkinson's disease is caused by a reduction of dopamine causing motor deficits. The investigators are studying how exercise can help PD patients by increasing dopamine release in an area of the brain that coordinates movement, the striatum. The investigators will enroll PD patients into two groups; one group will complete a 12-week aerobic exercise program and the other will complete a 12-week control program including yoga and stretching only. The investigators will measure changes in dopamine release before and after either 12-week intervention. Subjects will complete motor and cognitive questionnaires in addition to functional magnetic resonance imaging and positron emission tomography neuroimaging.

The purpose of this study is to document the long-term safety and tolerability after intracerebroventricular (ICV) administration of sNN0031 (PDGF-BB) in patients who participated in study sNN0031-001

Although deep brain stimulation of the subthalamic nucleus(STN DBS) has become the surgical treatment of choice for Parkinson's disease(PD), a consensus on the timing of surgery is lacking. This study is intended to demonstrate that early, compared with delayed, introduction of STN DBS is more beneficial for PD patients who have developed motor complications.

The aim of this study is to determine whether adherence to oral maintenance medications differs for patients randomized to receive a RxTimerCap, a Take-N-Slide, a standard pillbox, or none of these devices, with the hypothesis that low-touch devices improve adherence over control and that the increase in adherence is agnostic across devices.

The study of non-invasive and reliable biomarkers to track progression of Parkinson's disease (PD) is essential while disease-modifying treatments are being developed. Many clinical biological or imaging biomarkers have been tested but no "gold standard" has been found as of yet. Among these, Magnetic Resonance Imaging (MRI) relaxometry using R2* measurement (R2* = 1/T2*), which is a validated marker for estimating brain iron concentration, appears to be an attractive technique because its safety, rapidly measured in clinical conditions and its ease to ensure individual longitudinal follow-up. Current data of cross sectional studies of R2*, which have shown an iron increase in Substantia Nigra (SN), led to suppose that it could be a biomarker of disease vulnerability. Recently, the investigators have conducted the first longitudinal follow-up of R2* (1.5 T MRI), which showed a rapid R2* increase in both parts of the SN and in the caudal putamen. We propose, here, a multicenter prospective study of one-year cohort follow-up of R2* variations (ΔR2*) in three regions of interest (ROIs) (the SN, the Ventral Tegmental Area (VTA) and the Putamen) of 160 patients with PD, using a 3 Tesla MRI, to evaluate the potential interest of R2* as a biomarker of disease progression. The variation of R2* (ΔR2*) will be correlated with clinical markers of disease progress, non-motor symptoms. 80 healthy controls subjects will also be included to assess the effect of aging on cerebral physiological iron levels.

The purpose of this study is to evaluate the blood brain barrier in the striatum of patients that have other types of movement disorders compared to patients with Parkinson's Disease that are receiving similar treatment, to determine if a there is a disruption of the blood brain barrier in patients with Parkinson's Disease.

This study is a non-interventional post-marketing observational study (PMOS) of participants with advanced Parkinson's disease (PD) treated with Duodopa/Duopa in a routine clinical setting. Effectiveness of treatment will be collected with physician and participant/caregiver health outcomes beginning with PMOS enrollment (baseline visit), at the start of Duodopa/Duopa treatment via percutaneous endoscopic gastrostomy-with jejunal extension (PEG-J), at regularly scheduled visits closest to Months 3 and 6, and every 6 months thereafter up to 36 months. An additional cohort of participants will be enrolled who in addition will be evaluated with a wearable device.
