thank you John.

i think we need to be careful about invalidating an entire disorder (or "neurological reality" ), regardless of its etiology. I personally found your first post in this thread a little inflammatory in that sense, even if perhaps it was not meant to be.

I would certainly agree that it makes sense to try to frame things as correctly as possible... our understanding will hopefully increase as medical sciences advance.

here is the link to the article John refers to:
