Hi there Helping him. First i must say what a wonderful person you are to care so much about your friend to try and help him. I am in shock. Everything I know about Dementia (After 10 years) is that it points to age, lifestyle, lots of unknown stuff, but never this young age. I find it very hard to believe. I suggest getting in touch with Alzheimers Society. If they can't help you I don 't know who can. I really feel for your friend if this is true. Please keep posting. We all need to know what is wrong with your friend. (Or why it has happened to one so young.) Thinking of you and wishing it all goes well with helping your friend.xxxx
