ADD is a pseudo-disorder.
It is a collection of different sets of personality attributes and psycho-physio symtoms. The term obviously does harm to the kids who act like kids and get diagnosed with a disease for their trouble. The only reason the term exists is simply because we don't know what the conditions are that comprise it, what causes them, and whether and how to treat them. I invite you to join our society's rejection of the term. You'll get no flame war from me Maddie.
