Filter by:The overall goal of this research proposal is to develop an adjunct to standard treatments that 'correct' disrupted neural circuitry in Parkinson's Disease (PD) patients. Directly treating these core deficits via targeted behavioral training should slow the progression of PD, assure greater resilience against future decline, and improve the quality of life of many living with PD. The purpose of this exploratory research study is to determine the benefits, if any, of the mobile device-based treatment described above in individuals with PD.
Movement disorders such as Parkinson Disease, dystonia, and tremor are related to abnormalities of part of the brain known as the basal ganglia. Recently, it has been suggested that the basal ganglia works by oscillations (group of neurons cycle between activation/deactivation when stimulated) of electrical signals. A treatment that involves insertion of electrodes in the subthalamic nucleus (STN) for electrical stimulation, known as deep brain stimulation (DBS), is an established treatment for advanced Parkinson's disease. However its mechanism of action is still not completely understood. Currently, DBS utilizes an "open loop" system whereby the stimulation settings are manually adjusted depending on the patients' clinical response. 1. Determine whether the local field potential (LFP) recorded from the STN is stable over a 1.5 year period. 2. Address whether STN LFP is a suitable control signal, and how it should be used to change DBS parameters
Based on published animal and human studies, ExAblate Transcranial subthalamotomy can be as safe and as effective as any of the surgical treatments within the currently accepted standard of care including radiofrequency lesioning and Deep Brain Stimulation (DBS). A unilateral lesion of the subthalamic nucleus has shown reduction of contralateral motor symptoms in Parkinson's disease (PD). Using ExAblate Transcranial Magnetic Resonance guided High Intensity Focused Ultrasound (MRgHIFU) to create the subthalamotomy has several potential advantages over current therapies including the fact that transcranial lesioning can be performed in a precise manner with simultaneous as well as continuous clinical and radiographic monitoring. If the potential of ExAblate Transcranial subthalamotomy can be realized, it could supplant radiofrequency and radiosurgery techniques and provide a viable alternative procedure for subjects considering DBS.
Disruption of sleep and alertness is one of the most disabling non-motor symptoms of Parkinson's disease (PD). Mechanisms leading to impaired sleep and alertness in PD are not well understood, and treatment options remain limited. The proposed research will examine markers of the circadian system, sleepiness and sleep quality in PD patients. Further, the project will examine effects of bright light exposure on circadin function, sleep and alertness in PD.
The purpose of this study is to assess the safety and efficacy of long-term use of Duodopa in patients with Parkinkon's disease in actual usage
Primary Objectives: - Part 1: To determine the safety and tolerability of 4, 8, and 15 milligrams of GZ/SAR402671 (venglustat) administered orally for 4 weeks, as compared to placebo in participants with early-stage Parkinson's disease (PD) carrying a glucocerebrosidase gene (GBA) mutation or other pre-specified variants. - Part 2: To determine the efficacy of GZ/SAR402671 administered orally daily, as compared to placebo in participants with early-stage PD carrying a GBA mutation or other pre-specified variants. Secondary Objectives: Part 1: - To assess the pharmacokinetic (PK) profile of oral dosing of GZ/SAR402671 in plasma when administered in early-stage PD participants carrying a GBA mutation. - To assess the exposure of GZ/SAR402671 in cerebrospinal fluid (CSF) when administered in early-stage PD participants carrying a GBA mutation. Part 2: - To demonstrate overall safety and tolerability of GZ/SAR402671 administered orally for 52 weeks in early-stage PD participants carrying a GBA mutation as compared to placebo. - To assess the pharmacodynamic response to daily oral dosing of GZ/SAR402671 in plasma and CSF as measured by glucosylceramide (GL-1) when administered in early-stage PD participants carrying a GBA mutation over a 52-week period.
This is a single blind, randomized, wait-list controlled, phase II exploratory pilot study.
This project is investigating whether a home-based exercise program will reduce depression in patients with Parkinson's disease.
The purpose of this study is to determine if changes in brain serotonin affects the accumulation of amyloid in the brain. The investigators will use brain imaging methods to measure the amount of serotonin and amyloid in the brain of individuals with Parkinson's Disease (PD) and otherwise healthy older people. PD participants will undergo repeat brain imaging to assess amyloid accumulation two years after their first brain imaging session. All participants will undergo examinations to assess their motor function, and asked questions to assess their mood and thinking.
The purpose of this study is to provide proof-of-concept that directional stimulation and directional recording, in an intraoperative setting, is perceivable in a subject. The tests will be performed using a dedicated intraoperative lead connected to an external neuro-recorder/stimulator, during a deep brain stimulation implantation surgery.
