The study found that even those that "outgrew" ADHD still had one thing in common with those that still do have ADHD, and that's impairment in executive function. The thing is, ADHD seems to be a catch-all diagnosis for people having attention problems, and yet there might be multiple conditions that give rise to symptoms similar to classic ADHD. Consider SCT[0] for example. I know that Russell A. Barkley, who is a leading ADHD researcher tends to believe that "real" ADHD is the one that begins with hyperactivity symptoms in childhood (children diagnosed with the hyperactive-impulsive subtype), and those that don't have those symptoms (diagnosed with the primarily-inattentive subtype) have a condition called SCT, which is separate from ADHD.
