These days it's also a lot of pretty much random people who were sent to the school psychologist for some reason or other, plus a bunch of people who went to see a GP for things like a runny nose and were hoodwinked into a couple of psychiatric diagnoses they'll never get rid of, plus a lot of depressive narcissists who cling to their unfounded diagnosis to feel better about themselves, and the doctors play along because it's the easiest way to deal with them.

I suspect >90% of so called ASD cases have little real clinical basis these days and the entire disorder looks very fishy.
