Adhd and autism are closely related
My brother is autistic and I most likely have adhd (never got tested but after hours of research I have the same symptoms and struggles as a person with Adhd)
I have taken that test and it has come back as very high
When I take autism tests (which I know I don't have. I've been tested for that and I don't match my brother in those ways) I come as you might have autism every time.
