lots if math people are borderline autistic, which keeps them working obsessively on something. i think people call it asperger's syndrome, which is like autism's little brother.
I just read a book on autistic savants, among whom you find the amazing mental calculators, and another book on Asperger's syndrome. Neither of these diagnoses fit John Nash.
Nor does he fit squarely into any of the psychiatric diagnoses, although he was diagnosed as "schizophrenic". He is the only person I've ever heard of who has had such extended visual and auditory hallucinations involving recurring characters. Visual hallucinations are actually fairly rare in mental illness, and are generally not extended, and definitely not so coherent over so many years. I think John Nash has some undiagnosed organic problem.
i read in the paper that there's evidence to suggest that einstein & Newton had it.
The more I find out about Asperger's I think it is really, really unlikely that Einstein or Newton had it. They both may have had some kind of syndrome or very mild pathology, but I don't think it was Asperger's. Einstein, in particular, was too socially adept, too sensitive to social signals, to be given this diagnosis. His language delay almost rules Asperger's out since Asperger's kids tend to be the opposite: quite precocious, learning to speak and read before their contemporaries.
I actually know very little about Newton as a person except that he was a recluse and got into many heated arguments via letters. Asperger's people tend to be non-confrontational, and greatly dislike the stress of argumentation.
Some great people in history did, certainly, have major neurological problems about which there's little doubt: Julius Caesar and Dostoyevski had seizures, Samuel Johnson had Tourettes, Nikola Tesla had Obsessive-Compulsive disorder, Beethoven was bipolar (manic/depressive), but this suggested diagnosis of Asperger's doesn't actually fit in these two cases (or for John Nash).
