Parkinson's Disease

Frequently Asked Questions

25. Are there clinical trials for Parkinson's disease?

Yes. Parkinson’s disease clinical studies offer an opportunity to help researchers find better ways to safely detect, treat, or prevent Parkinson’s disease. NINDS conducts clinical studies on Parkinson’s disease at the NIH research campus in Bethesda, Maryland, and supports Parkinson’s disease studies at medical research centers throughout the United States. But studies can be completed only if people volunteer to participate. By participating in a clinical study, healthy individuals and people living with Parkinson’s disease can greatly benefit the lives of those affected by this disorder.

Current studies include genetics and Parkinson’s disease, search for Parkinson’s disease biomarkers, experimental therapies and other treatment options, diagnostic imaging, brain control and movement disorders, DBS, and exercise and Parkinson’s disease. For more information about NINDS clinical trials on Parkinson’s disease, see and search for “Parkinson AND NINDS.”
