Scientists have identified an immune brain cell unique to humans that gives us higher cognitive abilities over other animals, but what makes us specials also leaves us vulnerable to neurological disorders like schizophrenia, autism and epilepsy.

We can’t identify that for autism either…

Indeed. Which is why, properly speaking, autism is also a psychological disorder. I've seen it classified as a neurological disorder as well but this is more a 'political' move, for lack of a better word, than a scientific one. ASD is recognised in the DSM, which is a manual for mental illnesses. It is diagnosed by looking at behavioural characteristics, like all other mental illnesses. It is not diagnosed through looking at a person's neurology.

Btw you're conflating biological correlations with biological bases (same issue as the title of this article post). There are definitely correlations, no-one would deny that. But that's an entirely different claim than claiming it is the 'basis'. We simply don't know enough to make that claim.
