The trouble now is that, more than ever, Autism is a wide umbrella heading. If two people, Alice and Bob, have Autism, then they don't necessarily have the same thing, and the degree of similarity between Alice's Autism and Bob's Autism may be great or little.
There are many common features of Autisms* such as non-verbal, stimming, and so on. Then there are less obvious features, such as those described in books like Pretending To Be Normal.
*(and I think it best to pluralise: Alice has an Autism, and Bob has an Autism, but Alice's Autism may not be the same as Bob's Autism).
Part of the problem is the way the medical people like to apply diagnostic labels, as they do with physical medicine, and then try to reason based on those diagnostic labels. For example one may want to try a randomised controlled trial of treatments for Autism (without even considering the possibility that such a trial may not be comparing like with like).
Mind and brain are complex, and complexity is a bitch.
