I recently heard that about 70% are estimated to continue with symptoms into adulthood, which suggests 30% grow out of it. Is that possible for anyone to grow out of AD/HD? Or could it have been 30% received a wrong diagnosis in the first place?

Maybe the 30% were mild enough that coping strategies they learn as children are sufficient to help them "deal with it" as addults?

I agree with you atomx that maybe a good portion of the 30% learned great coping skills and/or lived in "very ADD Friendly environments"
