I have been watching Russell Barkley's series on ADHD. He mentioned the acquired one vs the genetic one.

I think he said the genetic one come with an underdeveloped front lope and another area of the brain which I don't know how to spell.

The acquired one came from injuiry or whatever.

What he said is that ADHD is really a lack of executive function to implement your ideas, and a number of other things, such as anixety, lack of self control, lack of emotional regulation... so on

So is Russell Barkley right on?

Are all ADHD curable? Are there ADHD that is incurable?
