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.
How does Alzheimer's disease affect the brain? Read how genetics, environment, and lifestyle play a role in developing early- or late-onset Alzheimer’s.
What are risk factors for Alzheimer’s disease? Learn about genetic and other risks for early- and late-onset Alzheimer's and steps you can take to stay healthy.
Read about the genetics of Alzheimer's disease. A genetic mutation can cause early-onset Alzheimer's. In late-onset Alzheimer's, a variant of the APOE gene increases 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.
