Active clinical trials for "Parkinson Disease"

The purpose of this study was to evaluate the use of resources during titration of Duodopa at home.

The aims of this study is to assess the efficacy of the crossover on balance in Parkinsonian patients and compare this results with the results of a control group of patients treated with a stabilometric platform.

The purpose of this study is to determine the impact of sleep and breathing problems during sleep on memory, attention, and general well being (quality of life) in people with Parkinson Disease.

Changes in deep brain stimulation (DBS) settings can have a delayed effect on gait function, which makes it impractical to optimize DBS for gait parameters in the clinic. Wearable movement sensors could be used to assess gait impairment in the patient's home hours after treatment adjustments are made in the clinic. This study aims to quantitatively evaluate the effects of turning off deep brain stimulation on lower extremity and gait function over three hours. This study will provide vital information about our patient worn system's ability to detect changes in lower impairment over time, which could be used to assist with DBS tuning for the lower extremities and gait in the future.

The " Behavioural Addiction and Genetics in Parkinson's Disease " study (BADGE-PD) is a national (France), multicenter, genetic association, case-control study to identify genetic factors associated with behavioural addiction (or Impulse Control Disorders, ICD) related to dopamine agonists treatment in Parkinson's disease (PD). Polymorphisms of candidate genes supposed to be involved in this adverse effect will be compared in 200 PD patients with ICD (n=200) and 200 matched PD patients without ICD (n=200).

This project studies the impulsive side effects of common treatments for Parkinson's Disease. By learning how parts of the brain involved in Parkinson's encode information related to reward and motivation, the investigators will better understand the reasons why Parkinson's patients often suffer from compulsive gambling, hypersexuality, and repetitive tinkering ("punding"). These results may lead to the design of better methods of deep brain stimulation (DBS) that minimize the behavioral side effects of Parkinson's treatment.

This is a double-blind, placebo-controlled, Phase IV trial , comparing HMS 90® versus placebo (soy protein) as add-on (adjuvant) therapy in subjects with idiopathic Parkinson's Disease. The principal objective is to evaluate the changes in biomarkers of oxidative stress and,plasma amino acids, as well as improvement of clinical symptoms and brain function

Most leading academic centers including Baylor College of Medicine (BCM) perform deep brain stimulation surgery in the awake patient using microelectrode recording to guide final electrode placement. Microelectrode recording is a means of analyzing the electrical activity of the brain, and assessing whether we have found the target for the deep brain stimulator electrode. However, no evidence exists that microelectrode recording improves patient outcomes. The use of microelectrode recording does extend the duration of surgery and there is evidence to suggest that microelectrode recording may increase the risk of bleeding in the brain during surgery.

Use lay language. Apathy is one of the most under recognised, underdiagnosed and poorly managed aspects of Parkinson's disease. Depending on methodological approach of the study, its prevalence is estimated to be between 16 and 51%. Apathy derives from a dysfunction of the dopaminergic meso cortico limbic systems, which seems to play a central role in the control of mood and motivation. The subcortical components of this system are the ventral tegmental area (VTA), the nucleus accumbens, and the constituents of the limbic system (particularly the hippocampus and amygdala), all of which are located deep inside the brain (18). The hypothesis is that depletion of striatal dopamine from regulators located in the midbrain (VTA and SNpc) in striato-thalamo-cortical circuits results in hypofunction of these circuits and the loss of frontal cortical activity, particularly within in the frontal orbital cortex, the anterior cingulate cortex and the prefrontal cortex The objective of this study is to explore, using diffusion weighted MRI, the regions of the brain which are proposed to play a role in motivation in apathetic Parkinson's disease patients and to define more precisely the relation between dopaminergic fibres and the meso-cortico-limbic system with the help of tractography methods

Multi-center, retrospective observational cohort study in 4 tertiary referral centers in Cairo over the period from 2004 to 2016. Study population. including all patients with idiopathic Parkinson disease attending. Patients were diagnosed in accordance to the United Kingdom - Parkinson Disease Society Brain Bank criteria.
