First, across all five datasets, transgender and gender-diverse individuals were 3.03 to 6.36 times as likely to be autistic than were cisgender individuals, after controlling for age and educational attainment. Second, transgender and gender-diverse individuals scored significantly higher on self-report measures of autistic traits, systemizing and sensory sensitivity and scored significantly lower on empathy traits compared to cisgender individuals. Third, in two datasets with available data, transgender and gender-diverse individuals had elevated rates of multiple other neurodevelopmental and psychiatric conditions. Finally, exploratory analysis identified that transgender and gender-diverse individuals were more likely to report that they suspected they had undiagnosed autism.

Well, that's concerning. I certainly don't believe in this "opposite brain" nonsense when the same researcher who initially published it later found it wasn't true by accounting for sexuality. Most likely these kinds are predatory, see also "pink pillers", and autistic people or people with insecure identities are most likely and most easily taken up by uprooting their ideas of themselves. It's not a stretch, after all, if you already feel yourself completely isolated or disjoined from human society. Just some guesses on my part.

What I sincerely wish to find or get would be something like this, but more broadly considering personality disorders in conjunction with developmental or psychiatric conditions. But this is a start.
