>E.g. ADD could be a "deficit" of attention, or it could be a "surplus" of attention

This is very true. Of the six types of ADD, one is "over focus". It is ironic that someone with attention deficit disorder can focus intensely on the same thing for 12 hours. I'm not an expert on the biology of it, but it seems like a problem caused by improper regulation of some chemicals in the brain, the same way improper regulation of insulin release can cause all kinds of problems.
