I just finished reading Send in the Idiots: Stories from the Other Side of Autism by Kamran Nazeer. It was a great follow-up read for me, having recently read Songs of the Gorilla Nation: My Journey Through Autism. The author of Send in the Idiots attended a small New York City school for autistic children about twenty years ago and uses this book to chronicle his reconnection with some of his former classmates. I really enjoyed his insights into his own adult life, as well as the thoughts he had on his classmates and teachers. He had a point toward the end of the book that many people stereotype autistics as savants with photographic memories, math whizzes or geniuses in some right. I've noticed this, as well.
While some people with autistic spectrum diagnoses have high IQs, that's certainly not true or all or even most. My personal experience with Bug, who does have a higher than normal IQ, is that it actually makes some aspects of his life more difficult. He often out-thinks himself (and us, for that matter.) Some of the other children I've worked with who have a more average IQ seem easier to get settled into a routine and less questioning. They also seem to think inside the box, where Bug spends most of his time thinking outside the box. While I realize this means he has the potential the discover great things in his lifetime, it makes for an interesting parenting challenge.
