It's a term that gets used sometimes for those who would be on the autism spectrum, or have diversity in how their brains work. Interesting numbers are being seen in the research literature around those who are neurodiverse more prominently presenting as gender-diverse as well. Sometimes that presents a barrier for a young person in getting care, for example, because they will find there is much more gatekeeping around accessing gender affirmation because they may also have an autism diagnosis.
