After many years of mental health treatment, untreated ADD has come up as a possibility. I have been prescribed accordingly, etc. so I'm not asking for medical advice. Anyway, For the past week I've been reading on the internet about ADD to educate myself about the disorder, but I've mostly found extreme views (ADD is a conspiracy manufactured by big pharma, turn to Jesus) that didn't present any evidence or sound arguments. So, is ADD 'real'? Is it overdiagnosed? Reputable sources/thoughtful replies preferred, since this seems to be such a contentious subject.
