I don't see anything in the articel regarding autism, but the newest research I've seen on autism seems to place the culprit for the autistic brain on another cell functioning apparatus. With this PVS problem, it appears a shutdown mechanism has over workled the function and now it takes some blocking agent to return the brain to normal functioning or near normal. If I can find it, I read a recent article in the BBC medical archives that addressed the latest findings on autism. I'll go dig a bit ... knew I should have linked to that one.
Just curious - I have no particular insight.
