Is ADD a real thing? Is that disorder questionable? Why do so many laymen roll their eyes about ADD?
I've honestly never been sure if ADD is a real thing or not. I can't tell if it's just a pop-psychology fad, or a real problem needing treatment and medication that a lot of people have. I'm sorry if this question is vague. What's the current scientific consensus on ADD/ADHD? Is it a legitimate disorder?
