I'm glad you posted this--I have read everything I've come across but still am confused about this issue. Our DD9 has been suggested to have a variety of things but if you actually look at whether she meets the criteria (and several psychologists have basically said that they're more guidelines/a concept than criteria per se (despite what it actually says in the DSM)) I think PDD-NOS would be correct. But after reading the James Webb Misdiagnosis book and some popular articles (e.g., about scientists/ mathematicians and how many of them are not 'normal' in terms of behavior) I really wonder whether this isn't part of the current trend to diagnose anyone who isn't within a very narrow range of NT behavior. On the other hand, I actually met a PG kid last year and also our nephew (now in high school) both seem completely NT to me. So I think it can happen

LOL
This.
My DD13 is very definitely (functionally) PG, though we've never had her
formally evaluated, so of course we don't
know that she's >145. Just based on comparisons with family members who range from 135-170, she seems to be at the high end, and a 3-4y skip has presented her with few problems academically (other than residual ennui). KWIM?
I consider her pretty NT. Maybe even
super-typical, in some sense. She's kind of an
anti-Aspie, though she shares some superficial characteristics that link her behavior to typical Aspie characteristics-- sensory sensitivities, etc. (In the sense of being anti-matter, if that makes sense.)
She's very definitely quirky. But far less so than many of the non-NT PG people I've known.
We've never seen a reason to have her 'evaluated' for anything in particular, though-- so it's entirely possible that she would earn one or more labels. But she seems completely functional to me.
