I read an article recently about some of the research Harvard scientists are doing to unlock the mysteries of autism. They think that autism results from genes that have failed to activate, rather than defective ones. They believe that someday they will be able to activate these genes, kind of like you would activate your new bank card by calling the number listed on the back. They have already had success "reactivating genes" on lab animals. I'm sure it is years, maybe decades, away....but a little hope goes a long way for us right now.
