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.
