Is alzheimer's disease inherited?

Likely yes: If there is a strong history of alzheimer's disease in the family like grandparents, parents, uncles, aunts, brothers or sisters, then you could be at risk of developing it.

Genetics: There are rare families with genetic risks, such as presenilin i or ii, and amyloid precursor protein mutations. Apoe epsilon 4 homozygous states can increase risk.

Some types yes: Alzheimer's disease with early onset at ages 40 to 60 has a large genetic component while alzheimer's with a late onset has a small genetic component.

Small percentage: There is a small percentage of Alzheimer's disease that's felt to be hereditary. Can do genetic testing to further delineate this issue.
