[Phantasm]

Speaking as someone who also has ADD (I lost the Hyperactivity part somewhere in my teens), the combination of Single-Minded to represent the hyper-focus along with Short Attention Span for representing the inability to focus on things that you are not interested in makes perfect sense.

In addition, at least in my case, I'd also tack on Laziness to represent the inability to do what you're supposed to in order to operate in modern society when you need to - like looking for job when you've been laid off. But that's just me.
