To some extent, we all have quirks or idiosyncrasies, and some geniuses, because of how bright they are and how focused they are, may have liberal eccentricities, but they're not at a disabling level.

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.

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.

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.

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.

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

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.
