WRT my comment below, not the poster you seemed to have replied to, I am not at all upset about investigating a disease, mental or physical, however, I believe the initial impetus was to lobby to look into it as a physical disease (worms, tiny bugs, whatever), and that was where my astonishment came from; 6 years of finding no chemical, or organism, or other physical disease-causing entity. Maybe I misread the link, but that's how I took it. I am sorry you took it the wrong way.
