Does anyone out there know any high functioning high level autism adults? Just curious. How do these people get along in life when they are no longer children, over 25, or even older? Do any of you personally know someone like this? What happens when ADHD people get really old? My husband's half brother has high level adhd and is currently about 45. We aren't close as they weren't raised together, and he lives far away (something I've always been thankful for !!) He still can't organize life - his mother purchased him a house in order for his 5 assorted children to have a "home", but that isn't working either - poor mother. . . . Do these people live to be 90, and then what happens?
