Filter by:This is a randomized, double-blind, two-part placebo-controlled parallel group outpatient treatment study that will utilize standard Parkinson's Disease measures to evaluate the effect of DNS-7801
The purpose of this study is to evaluate the safety and effectiveness of deep brain stimulation of the nucleus basalis of Meynert (also called the "nbM") at improving memory in Parkinson's disease patients with mild cognitive impairments and memory difficulties. Patients with Parkinson's disease (PD) that are eligible for Deep Brain Stimulation (DBS) therapy for improvement of their motor symptoms and with evidence of mild cognitive impairments and memory difficulties will be enrolled.
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.
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.
The purpose of the study is to learn about the impact of exercise on fatigue, anxiety, and depression in Parkinson's disease. It is well established that exercise improves the motor symptoms of Parkinson's disease. However, it is not clear which types of exercise are most beneficial for specific non-motor symptoms.
Parkinson's disease is not only a pathology of movements. There are many non-motor symptoms that complicate and impair patients' quality of life. Among those disorders are sleep disorders. Insomnia is the most frequent symptom. Most patients report 2-5 awakenings per night and long periods of awakening which occupy 30 to 40% of their night. Apomorphine is a dopamine agonist that may be administered with a pump . The objective of the study is to assess changes in the quality of sleep in Parkinson's disease patients treated with an apomorphine pump.
Physical activity has demonstrated its beneficial effect on functional capabilities and quality of life in patients with PD. However, the daily physical activity remains limited in these patients. Rhythmic auditory cueing improves spatio-temporal gait parameters in patients with PD. The first results of BeatHealth studies have allowed us to identify the best musical stimulation to improve these parameters and the motivation of the patients. The originality of this study is to propose a gait auto-rehabilitation program using BeatHealth device with optimal auditory cueing during four weeks in ecological conditions in PD. Observance (utilization's time), safety (falls, pain, fatigability) and efficacy (gait parameters, balance, quality of life) will be evaluated.
The purpose of this study is to assess the effect of tryptophan depletion on mood and behavior in Parkinson's disease (PD) patients treated with deep brain stimulation (DBS) of the subthalamic nucleus (STN). By doing this, the investigators hope to be able to identify risk factors for and mechanisms underlying psychiatric side effects of STN DBS. The study will be an intervention study with a placebo controlled, randomized cross-over design.
The primary objective of this study is to evaluate the efficacy of buspirone in combination with amantadine in reducing levodopa-induced dyskinesia (LID) in patients with Parkinson's disease (PD).
Many people with idiopathic rapid eye movement (REM) sleep behavior disorder (RBD) have an underlying synucleinopathy, the most common of which are Parkinson's disease (PD) and Lewy body disease. Identifying additional abnormal clinical features may help in identifying those at greater risk of evolving to a more severe syndrome. Because gait disorders are common in the synucleinopathies, early abnormalities in gait in those with RBD could help in identifying those at increased risk of developing overt parkinsonism and/or cognitive impairment. The investigators aim to identify subtle gait abnormalities in idiopathic RBD and to identify sensitive and early biomarkers: 1. to detect subtle gait disorders in pre-symptomatic stage of synucleinopathy and 2. to track their evolution in the parallel with the disease progression. Main objective: In comparison with age and gender matched-controls, to identify in patients with RBD a larger reduction of gait velocity (and other abnormalities of spatio-temporal characteristics of gait) between a single (gait) and a dual-task (gait+cognitive task). Secondary objective: 1. In comparison with age and gender matched-PD patients, to identify in patients with RBD a smaller reduction of gait velocity (and other abnormalities of spatio-temporal characteristics of gait) between a single (gait) and a dual-task (gait+cognitive task). 2. In patients with RBD to identify correlations between the spatio-temporal characteristics modifications of gait between a single (gait) and a dual-task (gait+cognitive task) and the percentage of REM without atonia - the dopamine transporter (DAT) density using FP-CIT single-photon emission computed tomography; the reduction of the olfactory discrimination and thresholds. 3. In patients with RBD to track the spatio-temporal characteristics evolution of gait over time (every 6 months for 2 years)
