I'm guessing based on my responses the articles are all correct and gifted kids tend to have the blended to NT looking ADHD. DS somehow isn't compensating at all. I guess the positive is that at least it doesn't mask his giftedness?
I don't know of any data that suggest that gifted people are more likely to have ADHD inattentive type than hyperactive type or combined type. I would instead look at it this way: kids whose behaviors are more extreme, or impulsive, or hyperactive, are less likely to be identified as gifted in the first place. The social stigma often gets in the way of correct identification.
ASD and ADHD often go together, by the way. Sometimes people manage this combination with both a stimulant (for attention) and an antidepressant (to manage anxiety).
