I won't dispute that the definition of ADHD as it exists in clinical guidelines is entirely too broad. I do think that there is a "condition" that exists in a smaller subset of the population that is described by the guidelines of ADHD, and it's not a sleep disorder or anything like that (in fact, my ADHD is far worse if I sleep too much.) But the article is potentially harmful because it discounts this population and pretends that there's nothing there. The author says "there is no such thing as ADHD" without allowing for the possibility that there actually is, but it's far too broadly applied and needs to be tightened up.
