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.

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 ways in which acquired savants show up are usually the same ways that congenital, or non-acquired, savant syndrome shows up. They tend to show up in the same areas: music, art, math, visual, spatial skills, and calendar calculating, although calendar calculating probably isn't quite as prominent in that group. They tend to show up quite quickly, or sort of explode on the scene and they then tend to have an obsessive sort of forceful quality about them in the same way as savant skills. So they tend to show up in the same ways.

When we come to research, if we want to find out the cause of autism, we're going to have to be much more specific, and that's why when it comes to research, I'm fairly strict with respect to criteria. When it comes to treatment, I'm much more open to not making that differentiation.

We can't use the word normal anymore because it's sort of come to be politically incorrect, because normal implies a classification, and categorizations, and exclusions, and so forth. So neurotypical is the word that we now have to use for what I call normal behavior. Neurotypical behaviors are those kinds of behaviors within the range of usual human conduct that do not rise to the level of a disorder.

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.
