Childhood Epilepsy

Great! 

I will ask at my Sons next review with his Peadiatrician 

I'm guessing that you might be referring to childhood absence epilepsy (CAE).

I'm not personally aware of any differences in the prognosis for CAE (or any other type of childhood epilepsy syndrome) in relation to autistic children versus others.

But we also need to be mindful of the rule, here, against offering medical advice. So I'd suggest that the best course of action would be to ask your son's doctor(s) about this.

The NAS has some more general information about epilepsy here, including links to other organisations that focus specifically on that subject. (I'm including these more for the benefit of others who come across your thread via search over time, but with a less specific question, but perhaps you might also find them of interest):
