Why does autism affect males and females differently?

1.21K viewsBiologyOther

So I recently got diagnosed with autism, and my therapist was talking about how it was most likely missed because of how different the disorder can show itself in boys vs girls.

So, why?

It looks like it’s the same over different populations, so I don’t think it’s anything to do with culture or anything like that. So is it something biological? Maybe it interacts with chromosomes or something?

I keep seeing things that tell me that it’s different, but nothing about why.

The other commenter – /u/icedragon9791 – is incorrect. There are a number of [studies](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8328919/) that associate autism with [hypermasculinity](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7026150/), based on a number of factors including facial morphology and brain scans. The variation in hormonal and neurological milieu may explain its different presentations in men and women.

A separate issue is that its presentation in women has historically been recognised less in diagnosis, due to the majority of studies being performed in men.
