Clinical Trials – Information for Participants


Clinical research trials are at the heart of all medical advances. Researchers enroll women, men, and children in clinical trials to test new ways to prevent, detect, or treat disease. Studies often enroll people with a specific disorder but some also accept people without health problems to provide baseline information on overall health.

To learn the basics about clinical trials, check out NIMH’s Clinical Research Trials and You: Questions and Answers brochure or visit the NIH Clinical Trials and You website.

Why Participate in Clinical Research?

People participate in clinical trials for a variety of reasons. Healthy volunteers say they participate to help others and to contribute to moving science forward. Participants with an illness or disease also participate to help others, but also to possibly receive the newest treatment and to have the additional care and attention from the clinical trial staff.

Clinical trials offer hope for many people and an opportunity to help researchers find better treatments for others in the future.

Join a Study at NIMH

NIMH, part of the National Institutes of Health (NIH), supports research studies through its Intramural Division on the NIH campus in Bethesda, Maryland. These studies enroll eligible participants from across the U.S. You can also learn more about studies conducted at the NIH using the following links:

  • Talk to your health care provider about local studies that may be right for you.
  • Search, the National Institutes of Health (NIH)/National Library of Medicine’s registry of federally and privately funded clinical trials conditions at NIH and across the country for a variety of diseases and conditions. You can also learn more about how to participate, refer a patient, or learn about results of studies. Please contact each research study team to learn more specifics. If you qualify for a study, then a study-related evaluation, treatment and, in some cases transportation to NIH is provided without cost to you or your health plan.
  • Join a National Registry of Research Volunteers, such as ResearchMatch. This is an NIH-funded initiative to connect 1) people who are trying to find research studies, and 2) researchers seeking people to participate in their studies. It is a free, secure registry to make it easier for the public to volunteer and to become involved in clinical research studies that contribute to improved health in the future.
