whats the youngest person that has been diagnose with Alzheimer's disease?

Answer 1

I could google this and find an exct answer, but im not going to. Dementia can hit at any age and developes at different rates in different people resulting in Alzhimer's. People with Down's Syndrome are very prone to early develop Alsxhimer's early and over 90% have full blown alzhimer's by the time they are 40. So the youngest person is likely to have been someone with Down's Syndrome.

Answer 2

"Early onset Alzheimer's" can strike people in their 30's. Supposedly there was a case of someone only 29 (see first link).
This article says anyone younger than 65 who gets Alzheimer's has "early onset" but I have read in other places that the "early onset" version is 100% genetic (with no environmental components).

Answer 3

i dont know if this is the youngest, but i worked with a man with down syndrome who was diagnosed with dementia (probably alzheimers) in his late 20's. people with down syndrome seem to have a predisposition to develop symptoms of dementia earlier than the "normal" population.

Answer 4

Early-onset familial AD, a rare form of AD that usually occurs between the ages of 30 and 60, is inherited.

There are several kinds of dementia and AD is just one kind.

Answer 5

I know very little except that my stepsister was disgnosed at age 47.....a real heartbreaker for everyone involved. She was always a little "different", but we never thought too much about it until diagnosis came in.

Answer 6

my stepsister was diagnosed with alzeimers at age 22
