I'd like to make a few points about possibly misdiagnosing ADD.
When I began art college, we were told by the professors that creative personalities tend towards lack of focus, easily distracted, easily bored, novelty seekers and sometimes lazy. We were told that we would need to overcome those natural tendencies and force ourselves to focus, finish, listen, etc. The entire freshmen class was warned about this. It was like they were mind readers with this incredible insight into our personalities!
We were not a class of ADD, although a methodical person might have thought so. Highly creative cream of the crop, but with all the bad aspects that come from that.

...I have found that, when giving him a task to do, he can only process one, maybe two in a row before he loses it. If I say, do the dishes and sweep the floors, then take out the trash....he only hears do the dishes. Then he goes to the bathroom and comes back and goes to his room for something and two hours later nothing is done.
