A US Study That Observes How Parkinson's Disease Changes Over Time in Patients Who Still Have Movement Symptoms Despite Taking Parkinson's Medications
This is an observational study in which data are collected and studied from Parkinson's disease patients who have movement symptoms despite taking standard Parkinson's medications. In observational studies, observations are made without any changes to the participant's healthcare or treatment plan. No investigational product will be administered in this study, …
Neural Correlates of Impulsivity in Idiopathic REM Sleep Behavior Disorder
This study aims to investigate the neural correlates (structural changes, functional connectivity, and structural connectivity of brain structures in prefrontal cortex and basal ganglia) of impulsivity by measuring structures and the blood-oxygen-level-dependent signal of brain in response to impulsive tasks and task-free using functional Magnetic Resonance Image method among healthy …
Investigating Complex Neurodegenerative Disorders Related to Amyotrophic Lateral Sclerosis and Frontotemporal Dementia
Background:Neurodegenerative disorders can lead to problems in movement or memory. Some can cause abnormal proteins to build up in brain cells. Researchers want to understand whether these diseases have related causes or risk factors.Objective:To test people with movement or thinking and memory problems to see if they are eligible for …
Improving Prognostic Confidence in Neurodegenerative Diseases Causing Dementia Using Peripheral Biomarkers and Integrative Modeling
To develop a model to predict disease progression in a large cohort of patients across a variety of neurodegenerative diseases, including Mild Cognitive Impairment (MCI) and dementia due to any neurodegenerative disease, including Alzheimer's Disease (AD), Lewy Body Disease (LBD), Vascular Disease (VaD) and Frontotemporal lobar degeneration (FTLD).
Investigating Neural Biomarkers for Gait in Parkinson's Patients
This observational study's main goal is to learn more about the neural mechanisms during movement in Parkinson's disease. Furthermore, it aims to inspire personalised treatment options.Participants will undergo a protocol that involves walking and gait-related motor tasks, such as seated stepping. During the protocol, brain activity will be recorded.
North American Prodromal Synucleinopathy Consortium Stage 2
This study will enroll participants with idiopathic REM sleep behavior disorder (RBD) and healthy controls for the purpose of preparing for a clinical trial of neuroprotective treatments against synucleinopathies.
Autoimmune Features of Neurodegenerative Disorders
This study is being conducted to better understand the role of inflammation in Parkinson's disease (PD) and Alzheimer's disease (AD). The investigators plan to recruit 30 PD, 30 AD/Amnestic Mild Cognitive Impairment (aMCI), and 60 age matched healthy controls in this study to study the role of immune response in …
Synaptic Loss in Multiple System Atrophy
In this study the investigators would like to investigate the degree of damage of the synapses, an important part of the neurons vital for the communications between neurons, in Multiple System Atrophy (MSA), and pathology related to abnormal accumulation of a protein named tau, in Progressive Supranuclear Palsy (PSP).
Chinese DENOVO PD Registry
The main objective of this longitudinal, multi-center study is to explore the clinical characteristics of PD and confirm biomarkers for PD evolution or progression.
DBS and Respiration
Patients referred to neurosurgery routinely and safely undergo deep brain stimulation (DBS) for treatment of neurological conditions, most commonly Parkinson's disease.The investigators have observed that respiratory problems (breathlessness) sometimes occur subsequent to DBS of the subthalamic nucleus (STN). This study aims to determine whether this is indeed a consequence of …
