Prospective Study to Compare Results of STN-DBS Between Early Treated and Late-treated PD Patient...
Parkinson's DiseaseDBS2 moreThe aim of this study is to investigate the impact of DBS not only no motor outcomes, but also on neuropsychological and psychiatric aspects and on quality of life in young patients with a short history of disease.
A Longitudinal Observational Follow-up of the PRECEPT Study Cohort
Parkinson DiseaseThe purpose of this study is to longitudinally follow consenting clinical trial participants who participated in PRECEPT (A Randomized, Double Blind, Placebo Controlled, Dose Finding Study to Assess the Efficacy and Safety of CEP 1347 in Patients With Early Parkinson's Disease). The study will assess the clinical and imaging outcomes relevant to the natural history of Parkinson's disease (PD), as well as determine early biomarkers of the disease.
Ambulatory Assessment of Motor State in Patients With Parkinson's Disease in Real Daily Life
Parkinson's DiseasePatients 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
Natural History of Levodopa-Induced Dyskinesia (LID)
Parkinson's DiseaseLevodopa is the main drug treatment for Parkinson's disease. Levodopa can cause unwanted and uncontrolled movements called dyskinesias (LID). The severity of these movements can range from subtle to extremely debilitating. These movements may or may not interfere with normal activities such as putting on a coat or brushing ones teeth. Current estimates of the occurrence rate of LID range from 12 % to 100% after one year of levodopa treatment. These estimates used reporting mechanisms such as self-report and doctor-reported. These reporting mechanisms are not reliable. We will use an objective measure of dyskinesia in the first 5 years of treatment for Parkinson's disease. The purpose of this protocol is to use an objective measure to estimate dyskinesia onset.
The Natural History of Parkinson's Disease-associated Spinal Disorders
Parkinson DiseaseIdiopathic Parkinson DiseaseThis is a prospective single-institution longitudinal study to access quality of life and serial imaging and biodynamic testing to assess spinal disorders associated with Parkinson's disease patients.
Molecular Analysis of Human Neural Stem Cells
Parkinson's DiseaseParkinsonismThe aim of this study is to develop and optimize methods to isolate, propagate and differentiate adult human neural stem cells from patients with degenerative neurological disorders like Parkinson's disease.
Cellular Proteome From Leukocytes of Glaucoma Patients in Comparison With Patients With Parkinson's...
Parkinson's DiseaseGlaucomaGlaucoma is a worldwide leading cause of blindness. The key feature of this ocular neuropathy is characterized by an excavating optic nerve head. Loss of retinal ganglion cells is the final end point in blinding diseases of the optic nerve such as glaucoma. It is known that neuronal cell death in glaucoma occurs by an apoptotic mechanism. In earlier studies the investigators could demonstrate that the process of apoptosis is reflected in circulating leukocytes by different parameters, like differential mRNA expression and an increased fragmentation of the DNA. Such alterations point out a relationship between cellular stress and apoptotic events. Based on the results of mRNA-expression the investigators also expect alterations on the protein level. This study is, therefore, designed to characterize the proteome related to the proteins involved in cell death related pathways. Thus, the expression pattern of several proteins in leukocytes from patients with primary open angle glaucoma will be analyzed by techniques like Western-blot and tandem mass spectrometry. These samples will be compared with samples from healthy controls. In addition, they will also be compared with samples from patients with Parkinson's disease. Since glaucoma is a neurodegenerative disease, these patients will be included as positive controls in this study.
Biomarkers in Neurodegenerative Diseases
Mild Cognitive Impairment (MCI)Alzheimer Disease (AD)9 moreThe general purpose of this observational study is to examine biomarkers associated with the pathology of neurodegenerative diseases to potentially develop novel therapeutic approaches.
Expanded Access of Pimavanserin for Patients With PD Psychosis
Parkinson's Disease PsychosisThe purpose of this program is to provide patients with PDP access to pimavanserin until the product receives marketing approval from the FDA and is commercially available.
A Follow-up of the Influencing Factors of Dyskinesia in Patients With Parkinson's Disease
Parkinson DiseaseDyskinesiasParkinson' patients who have not had dyskinesia would be observed for 2 years in a multicenter prospective study with the purposes to clarify the predicting factors of dyskinesia.
