Alzheimer's Disease Genetics Study

Start: June 2002
End: July 2026
Enrollment: 10000

What Is This Study About?

This study will identify and analyze genes associated with late-onset Alzheimer's disease. Researchers will collect genetic material from families in the United States in which two or more two living, blood-related individuals that have been diagnosed with or are showing symptoms of Alzheimer's disease or dementia. Participants will provide biological samples, such as tissue or blood. The biological samples and data from participants will be made available to qualified researchers. Results of individual tests are not available to participants or family members. For eligible families that do not live near a participating site, other arrangements may be possible to allow participation.
