A clinical trial is a kind of research study performed in people and aimed at evaluating a medical, surgical, or behavioral intervention. The NIA has information about clinical trials pertinent to older people. The NIA tip sheet Clinical Trials and Older People [1] can help you think about why you might consider participating in a clinical trial and how your safety is protected. If you are interested in clinical trials for Alzheimer’s disease, the tip sheet Participating in Alzheimer's Disease Clinical Trials and Studies [2] can help. Learn more about participating in research at NIH Clinical Research Trials and You [3].
