Is there a correlation between adhd and brilliance?

Maybe: Dr. Ed hallowell, author of driven to distraction, has often made that point. The person who manages well despite his adhd often has superior intelligence that has allowed him or her to cope despite his or her distractibility.

Perhaps: Perhaps. But I am not aware of any data 1 way or the other. I suspect that any one at any level of intelligence may have add/adhd.
