Thinking in Harmony -- a Different Kind of ADD?

I once mentioned, in a discussion with my wife and some friends, that the environment in my head is pretty crowded -- like a bunch of conversations going on all at once. This is true, except when I am listening to or composing music -- or even when I am playing. Otherwise, the old attic is full of people and they are chattering away.

When I said this about the "conversations," my wife said that this is a prime symptom of ADD. I disagreed with her diagnosis and began questioning how I could have achieved what modest academic, professional and artistic successes I have if I am an un-diagnosed sufferer of that learning disability (which, as you know, prevents focus in thinking -- or, at least, clouds focus).

Yesterday, I was taking a class on learning disabilities and we were discussing the various types of cognitive malfunctions and, as always, I found myself "hearing" several conversations at once: 1) one about my own childrens' learning styles by comparison; 2) one about students in my own school and how our program for "special education" works; 3) one about the content I was supposed to retain by the end of the class about documentation for learning disabilities; 4) one about the line between not discriminating against those with disabilities and overburdening schools 5) one about this blog post -- the workings of my own possibly learning-disabled mind; 6) one about my strategies for accomplishing my tasks for the rest of the day; 7) one about an idea for a composition that I have; 8) one about...well, you get the point.
