Have you read the PDF? It is whichever of the choices explains your lack of success in the real world, and this then brings relief from blaming yourself for that.

Really, that's it. Read the PDF.

The article even acknowledges that psychiatrist answer is wrong, and that all of the above are on a spectrum and nobody is ADHD-free or 100%-autist. This is not a problem because the answer is not meant to be correct, but only to be helpful and to "alleviate shame to enable people to achieve their fullest potential".

So there isn't even an answer.

Which, judging by your post, I'm guessing you will find a deeply unsatisfying way to look at the world, as you sound like someone with a positivist view (facts are correct and everything is true or false, you either have ADHD or not, and even on a spectrum there's a number. But there isn't)
