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.

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.

Not everyone who has a savant skill I would equate with a genius.

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.

The narrower we define autism, and the more strictly we control for particular behaviors, the more likely we are to find what I think are the subgroups of autism.

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.

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.
