Don't take my personal opinion and make it accountable to a professional one. I'm not a doctor. But before doing finance I used to do some basic tutoring and teachers assistant stuff for a place filled with kids with "autism" and there was a very wide array of personalities there.
As per dimensionality, yes that's what I was saying. Each symptom or descriptor exists on its own spectrum, not the entire disorder/illness/whatever it is medically classified.
Anyways, yeah. I don't know what's an illness, what's a disorder, I don't particularly care what the medical industry uses to distinguish those two words, but I've spent a chunk of time working with autistic students, and its close to my heart.
