We should probably start searching around a little earlier in our lives for what I call parallel activities, because most of us get entrenched in our careers. And, of necessity, we're earning a living, and it's taking our time, and we're building our résumé, and we want our résumé generally to be our proficiency within our field, because chances are we're going to be applying for another position within the field. So we tend to put off a lot of this sort of what I call parallel discovery until we're either very successful and have the time to do that, or more often until we're retired.

Parents don't particularly care whether it's early infantile autism or whatever label the clinicians have put on it. All they want is treatment, and they want what's best for their child, whatever that is. And when it comes to treatment, it may be that there's much more shared interventions that don't make any difference what label we're putting on it.

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.

Savant syndrome, characteristically, consists of left hemisphere dysfunction coupled with right hemisphere emergence, and what you see in the savant are basically right brain skills.

Now I realize, and I acknowledge, that the right brain/left brain distinction is a tremendous oversimplification. We don't come neatly divided into right and left hemispheres, but the fact is that the two hemispheres of the brain do specialize in certain functions.

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.

Savant syndrome is not a disorder in the same way as autism is a disorder or dementia is a disorder. Savant syndrome are some conditions that are superimposed and grafted on to some underlying disability. So savant syndrome is not a disease or disorder in and of itself. It is a collection of characteristics, or symptoms, or behaviors that have grafted on to the underlying disability.
