Active clinical trials for "Parkinson Disease"

Excessive free radical formation and depletion of the brain's primary antioxidant, glutathione, are established components of Parkinson's disease (PD) pathophysiology. While there is rationale for the therapeutic use of reduced glutathione (GSH) in PD, and even some preliminary evidence to suggest the use of GSH can lead to symptomatic improvement, obstacles surrounding currently employed delivery methods have hindered the clinical utility of this therapy. Intranasal GSH, (in)GSH, is a novel method of glutathione augmentation. The aim of this study is to evaluate whether 200 mg of (in)GSH results in measurable changes in brain glutathione concentrations, as measured by magnetic resonance spectroscopy (MRS) in 15 individuals with PD.

Treadmill training has been shown to be beneficial for reducing motor symptoms of Parkinson's disease (PD). The mechanisms for the therapeutic effects of treadmill training remain unknown. However, specific types of intrinsic feedback generated from muscle spindles (detect changes in length of muscle) and golgi tendon organs (detect muscle force) seem to be an important factor for achieving the reductions in motor scores. This study will compare a treadmill program that generates a high rate of intrinsic feedback to a treadmill program focused on generating a high magnitude of intrinsic feedback.

The primary objective of this study is to measure the efficacy of ABT-SLV187 in subjects with advanced Parkinson's disease.

This study investigates a treatment protocol which holds the potential to significantly improve communication and quality of life for individuals affected by Parkinson's disease (PD). Disorders of emotional communication are widely reported in PD and can negatively impact quality of life by increasing social isolation and decreasing independence. Individuals with emotional prosodic communication disorders are often perceived as depressed or unconcerned about others. This seeming negativity can cause difficulties in relationships, and increased feelings of stress and burden in caregivers which may result in earlier placement in an institutional care setting. This innovative treatment program could improve care for individuals with PD, as well as other individuals who may be affected by disorders of emotional prosodic communication (e.g., stroke or traumatic brain injury).

This is a phase 3, open-label, multiple-center, non-randomized single dose study to assess the safety and efficacy of [123I]NAV5001 SPECT imaging in aiding in the differentiaion of parkinsonian syndromes from non-parkinsonian tremor.

The purpose of the study will be to determine the effects of the Cognitive Orientation to daily Occupational Performance (CO-OP) as a treatment program for individuals with Parkinson's disease-related cognitive impairment. The potential effects of the CO-OP on successful engagement in meaningful activities will be examined from participants' and live-in caregivers' perspectives. Effects of the CO-OP on participant-perceived health-related quality of life and caregiver burden will also be evaluated. Hypotheses: Training with the CO-OP will have an effect or multiple effects on participation in meaningful activities and health-related quality of life for individuals with Parkinson's-related cognitive impairment. Training with the CO-OP will have an effect or multiple effects on caregiver burden and health-related quality of life for caregivers of individuals with Parkinson's-related cognitive impairment.

Parkinson's disease, a degenerative disorder of the dopaminergic system, combines motor symptoms but also non-motor, such as depression, sleep disorders and circadian rhythms and impaired cognitive functions. Difficulties in balancing the dopaminergic treatment of these patients emphasizes the need to find effective adjuvant therapies. Light therapy (LT) represents one such innovative therapeutic approach. Although light has an obvious to visual pathways within the brain, today it is known to additionally exert non-visual effects throughout the body. Recently our team has shown that non-visual, non-circadian light plays a major role in the regulation of sleep, as well as cognitive brain function in general. The retina, the primary conduit for the transmission of light information is weakened or thinned in Parkinson's patients. The dopamine system is known to enhance the processing of light information and intraocular injection of L-dopa in animal models of Parkinson's disease, can reverse associated motor symptoms. This allows for the possibility that LT would strengthen the dopaminergic tone in the central nervous system. However, to this date its effectiveness for alleviating Parkinson's symptoms has only been suggested by two studies, both poorly controlled. Thus, through the convergence of basic and clinical data, a study examining the effect of LT directly in people Parkinson's disease symptoms, whilst controlling for the effects on sleep, circadian system, mood, and cognitive functioning, is of extreme importance. With this information our hope is to determine if these polymorphisms allow for a predictive model of response to LT treatment.

This is an extension study to evaluate the long-term safety and tolerability of ABT-SLV187 in subjects with advanced Parkinson's disease.

The primary objective of this study is to evaluate the efficacy, tolerability and safety of single treatments of APL-130277 in 16 patients with Parkinson's Disease (PD)

A higher prevalence of Helicobacter pylori infection rate has been demonstrated among PD patients compared to controls. As H. pylori infection is known to interfere with levodopa absorption, we embarked on this is a study to understand the effects of Helicobacter pylori infection eradication among a selected Malaysian population with Parkinsons disease, in relation to levodopa effectiveness and motor improvements. The study hypotheses are: H. pylori eradication improves L-dopa 'onset' time and prolongs the L-dopa 'on-time' duration. PD patients with H. pylori infection show clinical improvement in motor disability and quality of life after eradication therapy of H. pylori, assessed using UPDRS-III / PDQ39 questionnaires.
