How do the symptoms of autism change over time?

Depends on child. Like all of us, children with autism continue to develop over time both physically and mentally. Puberty can have an especially profound effect--good or bad--both because of increased size and because of emerging cognitive skills. In general, aggressive behaviors grow less as children age into adults, but social interactions and language may actually diminish over time.
Depends. On method of treatment. This is a biochemical disorder and does require detailed nutrients. Call the autism research institute in san diego for referral to a "defeat autism now physician near you.
