My DS7 was evaluated for ADD/ADHD by a psychologist who has experience with gifted kids. We originally saw this psychologist for self-esteem issues with DS and eventually consented to a formal evaluation for ADD which it turns out he does NOT have. The symptoms that appear ADHD in our DS were related to his autism spectrum disorder and gifted-ness. I do not know who other people go to for diagnosing ADD...this is just our story! Nan
