Active clinical trials for "Parkinson Disease"

The investigators hypothesize that multi-session anodal tDCS (atDCS) of the left dorsolateral prefrontal cortex (LDLPFC) will induce long-lasting effects in improving cognitive function and reducing cognitive fatigue and fatigability in PD patients with MCI.

This study evaluates the effect of transcranial direct current stimulation (tDCS) on non-motor symptoms of Parkinson's disease, including depression and cognitive symptoms. Participants are randomized to receive active or sham tDCS for 30 minutes over 10 treatment sessions.

The purpose of this study is to assess the efficacy, safety, tolerability and pharmacokinetics (PK) of flexible doses of tavapadon in participants with Parkinson's Disease.

This study is designed to measure the change in patients diagnosed with Parkinson's disease (PD) before, during and after a 12 week exercise program.The focus of this study is the glymphatic system. The glymphatic system is a recentlydiscovered novel waste clearance pathway, in patients with Parkinson's Disease (PD).The glymphatic system acts as a waste-clearance system in the brain of vertebrate animals.The glymphatic system has been proposed in which new clearance pathways involving communication between paravascular spaces, interstitial fluid, and ultimately meningeal and dural lymphatic vessels exists, and we have provided evidence that this system may be dysfunctional in patients with Parkinson's disease with cognitive disorders. Early research suggest glymphatic function increases following exercise, this response is believed to clear beta-amyloid in the brain and may mediate the neurobehavioral response to exercise in PD. This study will use cognitive exams, neurological exams as well as specialized imaging to record data points and evaluate the glymphatic function after exercise.

NOPARK is a double-blinded randomized controlled phase II trial, with the aim to assess the efficacy of nicotinamide adenine dinucleotide (NAD)-replenishment therapy in the form of oral nicotinamide riboside (NR) in delaying the progression of early Parkinson's disease (PD). A total of 400 persons with early stage Parkinson's disease will be enrolled, randomized on nicotinamide riboside (NR) 500mg x 2 per day or placebo, and followed for 52 weeks.

Full Title: A phase II, randomized, open-label, double-blind, two-center study to evaluate the tolerability, safety and dose-finding of oil cannabis preparation for pain in Parkinson's disease. Short title: Cannabis oil for pain in Parkinson's disease Sample Size: N = 15 Study Population: Patients with Parkinson's disease and pain, without cognitive impairment. Study Duration: July 2018 - July 2019 Study Agent/ Intervention: Cannabis oil: mixed oil cannabis preparation consisting of 3 different formulations of ∆-9THC and cannabidiol - 18:0; 10:10; and 1:20 respectively. Cannabis oil will be administered orally once per day, as required for pain; or taken 4h before bedtime, if no pain. Primary objective: to determine the safety and tolerability of different formulations of Cannabis oil for pain in PD patients (incidence and severity of adverse events). Secondary objective: to assess change from the start of treatment (V2) to end of treatment (V5) in frequency and severity of pain, sleep, dystonia and motor symptoms in PD patients.

This is a randomized, double blinded, placebo-controlled Phase II study to investigate the efficacy and safety of ceftriaxone in patients with mild to moderate Parkinson's disease dementia (PDD).This study will enroll approximately 106 patients to have up to 84 evaluable subjects, and conduct in Chung Shan Medical University Hospital, National Taiwan University Hospital, Kaohsiung Chang Gung Memorial Hospital, China Medical University Hospital, Changhua Christian Hospital, and Taipei Veterans General Hospital.

To study the effects of Botulinum toxin type A (BTXA) in the treatment of foot dystonia-associated pain in Parkinson's disease

The purpose of this study is to obtain clinical outcome data on safety and effectiveness of the directSTIM DBS system when used on-label, according to the instructions for use. All participants will undergo bilateral implant in the subthalamic nucleus (STN) and data collected in common practice will be recorded during six months post-implant and analyzed.

The purpose of this study is to evaluate the safety and efficacy of 34 mg pimavanserin compared to placebo in patients with Parkinson's disease psychosis (PDP).
