So ADHD/ADD is a defect? You could say it is a defect, but ADHD/ADD may very well have been a critical survival trait for our earlier ancestors, helping them quickly identify possible predators. How could it be a defect in that case?
I don't think it works like that. This kid in my health class has it, and he just randomly shouts out his opinions (and I mean
shout). He also has these keys to his bike lock that he plays with and eats all the time. I know he can't help it because of AD(H)D, but that doesn't stop him from being annoying.
I guess it's a combination of not thinking before acting, and not being able concentrate on anything very well.
