I\’m an adult who was diagnosed with ADHD as a child (called ADD at the time). Thanks to the video that was on the front page a few days ago, I was recently introduced to the work of Dr. Russell Barkley. Much of what he said about ADHD being primarily an impairment of executive function sounded like it made a lot of sense, and it matched up very well with my own experience of my disability. Is this a well established theory of the cause and nature of ADHD? Is it well supported by the work of other researchers, or is Dr. Barkley on the fringe? If it goes against the consensus, then what is the consensus? Or what are competing theories?

Here\’s a video that summarizes his ideas.

EDIT: Here are a few more videos that better describe Dr. Barkley\’s theory of ADHD, executive function, brain morphology, and genetics:

• an hour long video

• the relevant sections from a long lecture for parents (this section and the four following)
