This whole thread is based upon nonsense and its premise is blatant anti-intellecualism.
Calling for evidence is hardly nonsense or anti-intellectualism. Clearly because of your association with Brady you are incapable of rational thought or of producing evidence for any of the claims that he has made concerning Fischer.
You're judging a book based an a sensationalist tagline that was, in all likelihood, placed on the cover by the publisher (since the publisher is the one who comissions and approves the cover), not the author. Read the book before you judge it or its author. It's actually one of the most balanced accounts of Fischer's life that I've seen.
Also: you'll not find a medical diagnosis for "madness" because "madness" isn't actually a medical condition or diagnosis. It's about on the level of calling someone an "asshole" (which, I'll contend, Bobby Fischer most certainly was. Perhaps the cover should have read "from America's chess prodigy to an asshole").
