My cousin has aspergers syndrome help?

Kayla Asked: My cousin has aspergers syndrome help?

He is 7 years old, abd he has aspergers syndome. Its bad in my opinion. Hes in therapy for help in using steps and jumping and running and stuff like that. This is getting worse the older he gets. Heres why:
1) his parents and teachers cant get through to him to tell him anything. Hes really smart but he doesnt listen. Hes just like rain man, only you can touch him more.
2) he throws a fit when you sont get him a sirprise whenever he sees you, if he cant spend the night, if u dont fix a certaib type of macoroni, or if he doesnt get what he wants for christmas or his bday.
3) he threatens his mom to punch her (hes done it before too) if she doesnt buy him a monster truck. And hes hit his little brother in the back so hard he starts crying. Hes gettin more violent the older he getals it seems like.

So do you guys know anything that can help them so that he can get easier to deal with?
