Molly > "It's genetic brain organization, optimized for a hunter-gatherer
lifestyle, and only an issue in modern society. Not an illness, not a
disease, a difference, with benefits and disadvantages"

This is a very common description of ADD, that it's a difference rather
than a true disorder.  Being an ADD guy myself, I used to find it
comforting.  Problem is, it IS a true disorder.  Just as arthritis is a
true disorder.  And MS.  And celiac disease.  And any of the other
grain-induced, autoimmune diseases of civilization.

Your comment that it's "only an issue in modern society" is true, if by
the comment you mean that only in modern society do we eat non paleo
foods.  The characteristics of ADD - mood swings, inattention, inability
to complete tasks, depression, inability to sit still - did not occur
prior to our abandoning our ancestral diet.  So in that sense we are not
wired differently than anyone else, it's just that we happen to show our
issues with the modern diet differently.
