A family health history can help you and your doctor know if Alzheimer's disease runs in your family. Learn about genetic and other risks for early- and late-onset Alzheimer's.
Read about the genetics of Alzheimer's disease and related research. A genetic mutation can cause early-onset Alzheimer's. Genetic variants influence disease risk.
Many, but not all, people with Down syndrome develop Alzheimer's disease when they get older. Learn about the connection between the two and how to participate in research studies exploring this relationship.
