Very interesting read I came across on Dr. Edward (Ned) Hallowell's site. In case you have been stranded on a desert island for the last 20 years, Dr Hallowell is a child and adult psychiatrist and founder of The Hallowell Centers. He has authored eighteen books on various psychological topics including attention deficit disorder best sellers Delivered From Distraction, Married to Distraction and Positively ADD.
The article on his web site talks about Emotional intelligence and ADHD being related;
"Emotional intelligence may be related to ADHD in that it is related to emotional maturity. In general, people with ADHD mature emotionally more slowly than their non-ADHD counterparts because their frontal lobes develop more slowly due to the effects of ADHD."
