I think you are right. There’s a lot of variety, and they keep recategorizing. Like apparently no one uses the term “Asperger’s” now, although it was common a few years ago.
Psychologist said my kid is an Aspie, that’s why I did so much research on the subject.
She wakes up, starts doing math problems at 6:30 in the morning and doesn’t stop until I put her to bed.
