The term "attention deficit disorder," as I understand it, is a bit misleading.

Attention disorders are about a deficiency in executive function, including a reduced ability to control one's attention (as opposed to just being a lack of attention). When disinterested, this leads to an inability to focus/concentrate. When it's something you like, this leads to "hyperfocus," whereby it's tough to pull away and behavior can be obsessive/addictive in nature. This latter symptom seems to receive less attention (edit: no pun intended :)). (And individuals and specifics differ.)

This is an oversimplification and I'm being a little loose with the vocabulary, but I wanted to at least briefly comment on the perceived "sketchiness" you mention.
