Who Gets Dementia?

Dementia is considered a late-life disease because it tends to develop mostly in elderly people. About 5% to 8% of all people over age 65 have some form of dementia, and this number doubles every 5 years above that age. It is estimated that as many as half of people in their 80s suffer from dementia.
