Active clinical trials for "Parkinson Disease"

A telephone call from a physician taking care of a patient in the hospital to a physician in the long term care setting at the time of discharge can improve transitional care for elderly patients. We believe direct communication between physicians can reduce re-hospitalizations, medication errors, morbidity and mortality. No studies have been done that involve physician-to-physician sign-outs after hospital discharge to the nursing home. In our study, we would like to address the breakdown in the transfer of information to the nursing home setting.

Ultimately a marker of microglial activation could be used for large-scale quantitative brain imaging trials in Alzheimer Disease (AD), Parkinson Disease (PD) or Multiple Sclerosis (MS), specifically to investigate the agent as an objective biomarker in treatments aimed at reducing inflammatory changes in these conditions. The significance of this work lies in applying state-of-art quantitative neuroimaging tools to develop a relevant biomarker in individuals with neurodegenerative diseases with the intention of using this efficiently in large clinical imaging trials.

This study investigates whether there is a change in 123iodine-2ß- carbomethoxy-3ß-(4-iodophenyl) tropane ([123I]ß-CIT) uptake after short-term treatment with levodopa compared to either dopamine agonist or placebo.

An open label, balanced, randomised, four-treatment, four-period, four-sequence, single oral dose, crossover Pharmacokinetics study of WD-1603 carbidopa/levodopa extended-release tablets in normal, healthy, adult human subjects under fed conditions. A single oral dose of (either Treatment A or B or C or D) carbidopa/levodopa extended release tablets will be administered to each subject within 5 minutes after completion of standardized vegetarian breakfast under fed condition in each period as per randomization schedule.

Cholinergic deficiency in the brain can be related to gait and balance problems in Parkinson disease (PD). Recent clinical trials suggested a beneficial role of acetylcholinesterase inhibitors (AchEI) on gait in PD. In this study, the investigators are planning to study the influence of AchEI on a brain network for gait and balance in PD. As gait problem is prominent in postural instability and gait disturbance (PIGD) subtype, this study will focus on the patients with PIGD phenotype.

A prospective, single-blind, parallel-group, randomised trial was conducted in Sao Paulo, Brazil. Thrid eight People with Parkinson's Disease were recruited and randomly allocated in two groups: Experimental Group (EG), that performed the balance and gait training based on games from Microsoft Xbox Kinect System ® (MXKS) supported by manual and verbal guidance (MVG) provided by a PT and a control group (CG) that performed an identical training with no MVG during the training.

Patients with an implantable electrical nerve stimulation system Patient criteria included: over 18 years of age,MMSE≥ 24 score; H-Y stage in medicine off condition>2.0;an ability to walk at least 10 meters independently;subscore≥2 for UPDRS part II item 15;subscore >1 for UPDRS part II item 14; permissions given by informed consent. Patients with serious diseases such as tumor, sever liver or kidney dysfunction were not selected in the clinical trials. Subjects participating in other clinical trials related or not related to these trials were not chosen.

The objective of this protocol is to investigate the microstructural alterations and monoaminergic function in Parkinson's disease patients with impulse control disorders and cognitive impairment by multimodal MRI and 18F-DTBZ PET imaging.

Potential for electrical stimulation to ameliorate Freezing of Gait (FOG)

Dystonia is a movement disorder characterized by involuntary, sustained, often repetitive muscle contractions of opposite muscles that lead to abnormal twisting movements or odd postures. Essential tremor is a slowly progressive neurologic disorder characterized by the appearance of a tremor during the voluntary movement. The pathophysiology of dystonia or essential tremor is not fully elucidated. Dystonia and essential tremor are associated with dysfunction of the sensorimotor basal ganglia-cortical network and involvement of the cerebellum and cerebellar pathways has also been recently suggested. The investigators propose to study 30 patients having a primary dystonia (15 DYT11 genetically documented), 15 patients having an essential tremor without deep brain stimulation and 15 patients having an essential tremor with deep brain stimulation.A group of 30 healthy volunteers will be recruited and tested according to the same modalities. They will be paired in sex and age. 30 patients having a Parkinson disease will be also tested. Eye position will be sampled with a video-based monocular eye tracker (SMI, Germany) before and immediately after an adaptation task. Saccade adaptation is evaluated as the percentage change in the mean saccade amplitude between pre-test and post-test. Expected results: no or fewer alteration of the performance to the adaptation task in the Parkinson group than in the Essential Tremor group/ dystonia group. abnormal reactive saccade backward adaptation in the Dystonia group and Essential Tremor group, providing further neurophysiological evidence of cerebellar dysfunction.
