Light vs. heavy weight training for Parkinson's disease
This study compares two types of weight training (lifting lighter weights versus heavier weights) in people with Parkinson's disease. It aims to see which approach best improves movement, strength, and daily function.
Coral Gables, FloridaAges 50–85 - NCT07745673Recruiting
Study of targeted treatment for Parkinson's disease symptoms
This study compares different ways of targeting treatment for Parkinson's disease symptoms. It is designed for people with mild to moderate Parkinson's who have had symptoms for at least 2 years and are generally stable on their current medications.
Wuhan, HubeiAges 40 years+ - NCT04239079Recruiting
Study of immune-related changes in Parkinson’s and Alzheimer’s
This study looks for “autoimmune-like” (immune-system) features in brain-related diseases such as Parkinson’s and Alzheimer’s, using genetic testing and other assessments. Results may help researchers understand what drives these conditions and who might be more likely to have immune-related changes.
New York, New YorkAges 55–90 - NCT00001215Enrolling by invitation
Understanding Genetic Lysosomal Storage Disorders
This study aims to understand genetic factors in lysosomal storage disorders—rare conditions where the body cannot break down certain substances. Researchers will collect information from patients with these disorders, their family members, and healthy volunteers to learn how these diseases develop and affect people over time.
