Your best bet to enroll in clinical research for an Alzheimer's disease treatment is to check the federal Alzheimer's Disease Clinical Trials Database, a joint project of the U.S. Food and Drug Administration (FDA), the National Institute on Aging (NIA), and the Alzheimer's Disease Education and Referral Center (ADEAR). Its website has a searchable database of clinical trials. You can also call (800) 438-4380.
There are two main kinds of clinical research. Clinical trials test drugs, devices, and other treatment interventions before they can be approved for general use. Clinical studies observe people and gather information that can be used to study changes over time as well as possible causes. Both kinds of research require thousands of volunteers with a variety of backgrounds.
Another good starting place is your doctor, who may know of local studies or who can refer you to nearby institutions conducting research.
