I have ADHD and an IQ which ranks up there at the borderline between Highly Gifted and Genius. Is this common among those of us with ADD/ADHD?

I also believe that I am an Indigo Adult. I believe that Indigo's are here to help usher in the Aquarian Age. I am also leaning toward a belief that Indigos are usually diagnosed with ADD/ADHD. I have never been treated for ADHD and I have always felt like I was never a part of any group but always on the outside looking in. Even as a child, I was the third among six children and the only boy. My mother referred to me as the "lone wolf".

Most people that I know whom also believe they are Indigo have a high IQ and also have been diagnosed with ADD/ADHD. Are they related? I would love to receive an opinion from you on this subject!
