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.

We have medicalized a lot of things that I think are not really medical conditions.

The term syndrome generally appears to be a constellation, or collection, of similar traits or behaviors within an individual. So, savants do have sort of a constellation of symptoms, which is characterized by some spectacular skill, or skills, coupled with this massive memory which is grafted on to some underlying disability. So those three conditions quantify, in my mind, the term syndrome.

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.

We have to be careful that we don't keep multiplying disorders and diluting them. I think there is a difference. People talk about Asperger's as high-functioning autism, which I think it is. But it does have some of its own characteristics, like the preservation of language, particularly, which may be right brain dysfunction instead of left brain dysfunction, and we lose something in that, as things lose their specificity, and we keep diluting things. I'm not sure that's helpful.

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.

With respect to why some acquired savants are musical, and some are good at the arts, and some are mathematical, why aren't they all the same; I think that has to do with this genetic endowment that all of us have.
