Active clinical trials for "Parkinson Disease"

The primary purpose of this study is to characterize the acute anti-dyskinetic properties of intravenous levetiracetam in Parkinson's disease patients who have been optimized on antiparkinsonian medication. The secondary objective is to study the effect of intravenous LEV on additional motor and cognitive symptoms of PD.

The purpose of this study is to determine whether F-18 FPCIT is effective and safe radiopharmaceutical for the objective diagnosis of Parkinson's disease.

Outcomes study to test the hypothesis that patients first identified by community-based neurologists, implanted by a networked movement disorders center, and then managed by the same community-based neurologist will have clinical outcomes comparable to movement disorders centers.

The aim of this trial is to verify that neurostimulated parkinsonian patients gain weight and to study its link with an energetic balance change.

Study participants who have been clinically diagnosed with Parkinson disease will receive no treatment, treatment with either levodopa, or treatment with Mirapex for a period of 12 weeks. Over the course of the study subjects will travel to the Institute for Neurodegenerative Disorders (IND) in New Haven, Connecticut for brain imaging.

20 patients with idiopathic Parkinson's disease, who are planned to undergo intestinal L-Dopa + entacapone (Lecigon®) treatment will be included into this observational single-armed study. These patient will be observed for hyperdopaminergic complications and neuropsychiatric fluctuations postprocedure at 3, 6 and 12 months.

BioGenParkinson is an observational, prospective cohort study evaluating biomarkers of Parkinson's Disease (PD) progression in community-dwelling subjects aged 65 years or more, consecutively referring to INRCA outpatient clinic of the Neurology Unit. Selected patients will undergo clinical and laboratory evaluations at the baseline, and will be followed up after 6 and 12 months. The biological evaluation will include the determination of i) routine biological parameters ii) advanced biomarkers such as epigenetic analysis of DNA methylation, genetic analysis on multiple loci associated with PD progression and specific proteins associated with motor and non-motor decline. After obtaining all data, multiple statistical analysis will be performed to evaluate the most accurate prognostic biomarkers of PD progression at this stage of disease.

Study Purpose: Parkinson's disease leads to severally impaired motor control. The purpose of this study is to better understand and analyze the characteristics of arm muscle activity while doing some reaching tasks and of leg muscles while walking. This will allow the investigators to improve understanding of the mechanisms underlying the motor impairments in Parkinson's disease.

In France, an estimated 860 000 patients are affected by Alzheimer Disease (AD) which represents, as in other developed countries, a major public health issue. In many cases, AD diagnosis is uncertain and its clinical evolution unpredictable. The exactitude of the diagnosis is however particularly important in the perspective of the validation and use of new therapeutic strategies in AD. Detection of cerebrospinal fluid (CSF) diagnosis biomarkers fell short in the detection, of atypical/mixed cases, of some differential diagnosis, and in differentiating rapid or slow clinical evolutions. Hence, CSF analysis gives a unique opportunity to detect and validate biomarkers in many neurological disorders. Nevertheless, in medical practice, CSF biological analysis is currently limited to a small number of analytes.Quantitative and targeted mass spectrometry, especially operated in the Multiple reaction monitoring mode (MRM), represents an alternative to immunodetection and could be used to detect specific biomarkers in complex matrices such as plasma by specifically discriminating the proteotypic peptides corresponding to each proteins. Mass spectrometry has also the ability to distinguish and quantify isotopically labelled and unlabeled selected targets. This ability was used in a publication by the group of R. Bateman (Washington University, St Louis, USA) who could, after administering stable isotope-labelled leucine, evaluate Ab synthesis and clearance in humans. This approach has an enormous potential to study the metabolism of proteins within the human CNS and consequently help in the understanding and diagnosis of neurological disorders.The main objective of this program is set up a targeted quantitative mass spectrometry method for existing and stable isotope-labelled CSF biomarkers in the neurological field; exploit this approach for diagnostic purpurses and to gain knowledge in the pathophysiology of diseases.

Breathing is a complex process, which can be controlled through voluntary command or neural control. Parkinson's disease (PD) is a progressive neurological disorder. Many individuals with PD experience respiratory problems, such as coughing difficulties or shortness of breath. Changes in neural control of breathing could be part of the reason of these respiratory problems. This study will measure whether neural control of breathing is impaired in individuals with PD compared to healthy individuals.
