When I hear trans people speak of how they realised growing up that something wasn't right and they felt different from others and struggled to conform to societal expectations, it resonates so strongly with my own experience of trying to conform to neurotypical expectations with an undiagnosed neurodevelopmental disorder.
I wasn't diagnosed as neurodivergent (ADHD) until my late 30s, but I had spent my whole life feeling I didn't fit in and desperately trying to figure out why.
The only reason I never considered gender dysphoria as an explanation was because I've always had a firm belief that gender's a social construct, so that explanation would have made no logical sense to me. But if I had believed that gender was an actual thing, I absolutely would have taken gender dysphoria to be a plausible explanation, because the trans existential experience appears identical to my own.
I don't think many people realise how much neurodivergence can affect people's self-perception and their experience of the world, and I personally believe that this is the reason for many misdiagnoses of gender dysphoria.
IMO, neurodevelopmental disorders should be ruled out as part of a gender dysphoria diagnosis, because ASD and ADHD (and any sensory/executive dysfunction) can have such a significant impact on one's perception and sense of self, along with a lack of awareness on the part of the patient.
