If swim is distracted by shiny objects and bright lights does he have ADD?
SWIY is much more likely to have Aspergers based on that brief description. Aspergers is high-functioning autism, and it is related to ADD in that it is a cortical stimulus disorder.
People with Aspergers typically combine high intelligence with autistic symptoms such as the shiny objects thing SWIY has just described.
Aspergers and ADD are often (and wrongly) cross-diagnosed. I was diagnosed with Aspergers before I was diagnosed with ADD. The Aspergers diagnosis turned out to be wrong. The specialist who finally worked this out based his opinion (in part) on the shiny object and bright lights distraction thing (which I don't have). The other thing he based his opinion on was eye contact and other empathic behaviour. Aspergers people have difficulties with these.
The current clinical view is that ADD and Aspedgers are mutually exclusive.
