> It’s the long list of diagnoses Maya collected before she was 21, from borderline personality disorder to agoraphobia to obsessive-compulsive disorder, that begin to hint at how little we understand autism in women.

That doesn't follow. It could simply mean that she had really bad psychiatrists who just threw around diagnoses. Maybe it reflects that mental illness in general is poorly understood, because they didn't discover that the other diagnoses were false positives. I am afraid that unless a diagnosis is followed by a successful treatment, it's not worth much.
