Clinical Trials in Parkinson's Disease

What are Clinical Trials?

Clinical trials are research studies on humans that are designed to answer specific questions about vaccines or new therapies, to test new ways of using known treatments, or to find out more about a disorder.  For information about clinical trials in general and at the NIH, please go to NIH Clinical Research Trials and You or Learning about Clinical Studies.

Finding a Clinical Trial

NINDS has developed several means of locating information about NINDS-sponsored clinical trials, which include studies on the NIH campus in Bethesda, Maryland, across the United States, and around the world.

  • Patient Recruitment for Studies includes information on studies conducted by NINDS physician/scientists at the NIH Clinical Center.
  • NINDS Clinical Trials features descriptions of a selected group of NINDS-sponsored trials organized by neurological disorder. This page also provides access to additional trials.
  • Selected trials are highlighted on the neurological disorder pages accesses under Disorders A to Z on the NINDS home page.

The National Library of Medicine has developed, a comprehensive searchable database, to provide current information on clinical research studies sponsored by the NIH and other Federal and Non-Federal Entities. Go directly to to search independently for studies, or use the following search boxes for studies on selected neurological disorders with particular sponsors. People interested in participating in any of these studies should ask their physicians to contact the individuals noted in the study descriptions.

  • Studies conducted by the NINDS at the NIH in Bethesda, MD.
  • Studies sponsored by NINDS throughout the United States and worldwide

In addition to NINDS, other NIH Institutes also fund and conduct clinical research on neurological disorders.

  • Studies sponsored by NIH throughout the United States and worldwide
  • Studies across the United States and worldwide regardless of sponsor

For all studies at the NIH Clinical Center, patients can search using Search the Studies – NIH Clinical Research Studies.
