The Alzheimer's Disease Genetics Study is a nationwide study to find the genes that play a role in late-onset Alzheimer's disease (AD). Scientists hope this all-out effort will speed the discovery of the genes that increase the risk of AD in later life and of ways to prevent it.

The AD Genetics Study is seeking families with two or more living siblings who have been diagnosed with AD. Volunteers should be aged 60 or older. A third family member also is needed—this family member may be either affected or unaffected by AD. Local sites will collect clinical and demographic information from the families for the National Cell Repository (NCRAD) at Indiana University. All information will be kept confidential. This study does not provide medical treatment.

Next Steps
People interested in participating in this study can call the toll-free NCRAD number, 1-800-526-2839, for more information. Study sites are located throughout the U.S., and arrangements can be made for eligible families who do not live near a participating site.
