While I am in no position to understand the paper, the possibility of AuDHD being a different pathology is exciting to me.

It makes a great point on why we should pursue a dual diagnosis instead of focusing only on one side of it, regardless if that is ADHD or ASD. It's a different problem and there is no guarantee that remedies for either pathology are going to help AuDHD people.

It's disappointing how little research there is on AuDHD, and hopefully findings like this are going to help us get more attention to our problems.

I didn't get diagnosed with ADHD until I pursued it viciously as an adult. I always wonder how I could have actually been treated as a child instead of dealing with doctors arguing if I was ADHD or ASD, as I could only be given one label back then (2000s). Good to see that there is now research being done on this and that we are moving forward finally.

Do you still have the pdf of the paper? I couldn't access it through the links you provided and it's not on Sci-Hub yet. It looks interesting and I'd like to read it :)
