Causes of Alzheimer's Disease
Scientists believe that a combination of genetic, lifestyle, and environmental factors influence when Alzheimer’s disease begins and how it progresses.
In Alzheimer's disease, damage to the brain likely starts a decade or more before memory and other cognitive problems appear. Learn about the toxic changes occurring in the Alzheimer's brain.
A combination of age-related brain changes, genetics, and factors related to health, environment, and lifestyle may play a role in the development and course of Alzheimer's disease. Get more information.
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.
