My IQ is in the 150 range, and I was diagnosed with ADHD. I feel very pompous announcing my IQ, so I will just add that I have other issues, and I think IQ is vastly overrated. We are all very stupid, it's just a matter of degree I guess. I've been told I'm an indigo, and am on the fence if that is even a thing or not. My closest friend is also a diagnosed ADHD. I don't know his IQ but I'm fairly certain it's high.
