My friends brother is 20 years old and is starting to have a really hard time. Aparently he had some kind of breakdown while he was in his first year of college. I wont get into specifics but it seems like hes holding a huge grudge against all of his family (for no good reason) who is literally doing every thing they can to help. They (sister brother in law brother) try to show him a good time, take care of him, etc. His mom and dad coddled him growing up. Everything including college is paid for. 

While staying at my friends he was left alone for about 12 hours and drew all over EVERYTHING. He went to a phsycologist and was prescribed meds (not sure which ones) which i think is adding fuel to the fire honestly. Hes not a drug addict although he cant handle his liqour, weed etc. So i guess you could say he has a very addictive personality but hasnt gotten on the hard stuff. 
I dont understand how this could happen all of a sudden. Its so disturbing and sad to hear the disrespectful things that come out of his mouth. All he can do is attack everybody around him and then get super defensive when people try to talk to him. I wish i could help but I realized that being rational wont work.

Im trying to to organize my thoughts better so here is a list of things I think are wrong.

-lack of empathy towards the people who love him unconditionally
-Not being able to read social cues
-Saying random and untrue things in the middle of a conversation
-Turning very angry for no reason at everyone in a matter of seconds
-Trying to get everyone to feel sorry for him
-drawing all over everything

Does this sound like autism or is it possible to get a brain disease that causes you to mentally deteriorate?
