As per other siblings, not necessarily actual dementia but symptoms of dementia and the people that are supposed to be able to distinguish these can't/won't/don't. Another not too uncommon one can occur in older people even when they aren't on drugs: dehydration. The tests they do in hospital to see if you have dementia can easily misdiagnose as dementia when you're simply being dehydrated. Now imagine giving this test to a 30 year old vs. a 75 year old. I've personally seen it attributed to "this person is old, must be dementia". Made sure to hydrate regularly while in hospital (which nurses couldn't/wouldn't/didn't) w/ perfect recovery from their "dementia".
