Filter by:This clinical study is a double-blind, randomized, placebo-controlled trial to investigate the effects of melatonin on the sleep disturbance symptoms of Parkinson's disease patients, symptoms which have a significant impact on the quality of life of these patients.
Parkinson's disease (PD) affects more than 100,000 Canadians and results in symptoms affecting both motor and cognitive (thinking and memory) functions. Parkinson's disease with Mild Cognitive Impairment (MCI) frequently results in development of dementia for which few treatment options exist. Transcranial Magnetic Stimulation (TMS) is used to alter activity in the outer regions of the brain and has been shown in previous studies to increase cognitive performance in patients with different disorders. This study will investigate the effectiveness of TMS as a clinical treatment for the cognitive deficits associated with Parkinson's disease. 64 male and female participants between the ages of 50 and 90 will attend eight study visits over a period of 63 to 66 days. This study is a double-blind randomized clinical trial meaning the participant will be assigned by chance to either the TMS-treatment group or the Sham-treatment group. Additionally, a combination of memory and thinking tests and Magnetic Resonance Imaging (MRI) will be used to see if there are structural and functional changes within the brain. Genotyping and blood analysis before and after treatment for different biomarkers will also be performed and these data will be compared to the TMS data. Initially, this research will increase knowledge about the effects of TMS on various brain regions. Ultimately, we will be able to determine if TMS can be used as a complementary therapy for PD to improve cognitive performance and to reduce progression into dementia.
This study aims to develop and evaluate biomarkers using non-invasive optical coherence tomography (OCT) and OCT angiography (OCTA) as well as ultra-widefield (UWF) fundus photography to assess the structure and function of the retinal and choroidal microvasculature and structure in persons with mild cognitive impairment (MCI) and Alzheimer's Disease (AD), Parkinson's Disease (PD), or other neurodegenerative disease, diseases as outlined.
Depression is common in Parkinson's disease (PD), but the effective treatment is not established yet. tDCS is a non-invasive brain stimulation to modulate brain function. The tDCS on the depression in general population were already conducted, but not in PD. This study is to know whether transcranial direct current stimulation (tDCS) is effective for the treatment of depression in PD. Participant will be asked to visit three consecutive days for the non-invasive stimulation.
This study is a double blind comparative study examining the effectiveness of the rTMS treatment on Freezing of Gait (FOG) in patients with Parkinson's disease (PD). The investigators hypothesize that treatment with rTMS on supplemental motor area will improve gait quality and decrease the frequency of FOG in PD patients.
The Measuring Parkinson's Disease Progression study aims to use MRI scans and a controlled dose of levodopa to find a biomarker (objective measurement) of Parkinson's disease (PD). Biomarkers would help determine the effectiveness of therapies in slowing or stopping PD progression, and accelerate the pace of research.
This is a phase IIa, first in human, randomized, double-blind, multicenter study to evaluate the safety, tolerability and efficacy of DA-9805 at 45mg, 90mg versus placebo in subjects diagnosed with early Parkinson's disease.
A cardiac safety study of an investigational drug to see how it affects the heart in people with Parkinson's Disease Complicated by Motor Fluctuations ("OFF" Episodes)
The purpose of this study is to determine if droxidopa reduces fall risk by improving gait speed, kyphosis, and functional reach in individuals with Parkinson's disease.
The study investigates the effect of dopaminergic stimulation over declarative memory functions in Parkinson's disease (PD) patients. At this aim, 20 PD patients will receive declarative memory tasks in two different conditions: after 12-18 hours of dopaminergic stimulation withdrawal ("off" condition) and after the first daily dose dopaminergic therapy ("on" condition). 20 healthy controls will also administered the two tasks in two conditions with the same inter-session delay as PD patients, but without taking drugs.
