I think that if I could do any sort of research of autism that I wanted to do, at this point I would take a sample of classic, early infantile autism persons and compare them with what I call "classic late onset autism", individuals. I think we will find that the cause of those youngsters with autism who have autism from birth is probably different than those who have late onset autism.

Quotes from the same author

There are some cases that have come to my attention where there's been a head injury, or getting struck by lightning and surviving, with really no disability or residual. So there are cases that I'm aware of where there's been some incident which triggered the acquired savant ability, but is not associated with long term disability, so that can occur. But I think that's probably the exception rather than the rule in that I think many of the acquired savants do end up with some residual disability.

When I met my first savant in 1962, I was impressed by the abilities in these youngsters who had severe disabilities. They appeared to me to be islands of genius in the sea of disability. So I've maintained that word picture since that time, of these islands of genius that are so striking and so jarring when you see them, especially in people who have severe disability.

A savant, by definition, is somebody who has a disability and, along with that disability, has some remarkable ability. Prodigies and geniuses have the remarkable abilities that the savant shows, but they do not have a disability. So, by definition, a savant includes someone with a disability, and a prodigy or genius are people who have these remarkable skills but they do not have a disability.

There are people at the extremes who aren't able to do anything musically, and then others sort of fall in the middle. And the same thing with math, and the same thing with art. You'll find people who are geniuses, or prodigies at the far end of the bell shaped curve, and I think you will find some of the acquired savants in that category who happened to have been endowed with that kind of talent, which explains why not everyone becomes an acquired savant.

I have a fairly strict definition of early infantile autism. That is not to say that people who don't meet that classic description don't have autism, but we might do well to narrow our definitions, and our samples, down to groups that are very similar, because I think you're more likely to find the cause.
