Originally when we talked about language disorder it was a catastrophic language disorder. It's substantial, and from a treatment standpoint it's okay to keep diluting that term, but from a research standpoint we need to be much more precise. I wish somebody would take up the mantle of just that particular task.

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.

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.

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.

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

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

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.
