i dont kno much about it but i have known kids with that problem. usually the big 1 is they dont pay attention, they dont listen to you at all, scream and get mad and throw fits for anything. they dont interact well with other kids. they dont share toys, are very protective of their own things like toys and stuff. and thats all i can think of right now.. nd treatment it depends some kids have low levels others high, some are in pills and medicine [wich is bad because medicine makes youre system even worst]. then again alot of doctors these days say kids have autism and deep inside its just spoiledness, my little sister for example, we used 2 think she was autistic, then we found out shes juss spoiled and raised wrong. also this syndrome or w.e you call it is seen by age seven, but u can see it as early as 3. hope i helped

My brother is autistic, but I cannot really tell you about symptoms because everyone is different, and severity varies greatly.

Hope this helps.

Some are very functional others not so. I have a young friend (a boy) with autism, he's a great kid and fun to be around. he goes to a special school to learn, he has problems with regular school

try reading what the Autism society has to say

Hmm most are prisoners of routine. Many are low functioning, some are higher functioning.

My son is autistic, he's 17 and I'm still learning…..how long do you have
