You get at something that I'd meant to say as well...my gut reaction was fuck you and your cure, when I first saw the book.

That, and while I'm not a neuroscientist, I don't think sorting this kid's brain chemistry by antibiotic alone would be enough to end his OCD symptoms. I've found that a lot of behaviour becomes so entrenched that it's hard to eradicate. Maybe they go into therapy or something in the book, but...I don't know.

And then we get into the whole 'does having OCD mean you're not neurotypical' issue, thanks to the author linking PANDAS somehow to autism...I do not even know.
