@nprofile1q... @nprofile1q... I was also wondering about the reverse. The proportion is really about how common ADHD is compared to autism. And we don't really have reliable data on that. Like: we have data of diagnosed children saying that boys are twice as likely to be diagnosed which essentially means that girls are still massively underdiagnosed. Data on races (which is often just a proxy for poverty) indicates the same thing. Overall it seems that ADHD is more common than autism. But that would mean that these "60-70%" become almost 100% for the reverse. Which is strange: ADHD is definitely very common within the autistic population but it isn't universally present.
