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.

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.

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.

The beginning of wisdom is to call things by their right names in research.

Savant syndrome and autism, I think, are not disorders of brain structure, but they're disorders of brain function.

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.

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.
