Right, but both ADHD and Autism don't have clear neuromarkers, we diagnose people largely based on their symptoms (or the results of their symptoms). The stuff you describe (being bored by regular people, your place being a complete mess) can have "ordinary" reasons, but can also themselves be symptoms of neural disorders. If you have a bunch of symptoms that you've dealt with for years and that you also (succesfully!) take the same medication for that people with the disorder take, I think it can actually be difficult to clearly delineate what is causing it.

Also your example is kinda dumb! You don't have to have Alzheimers to be forgetful, it's actually quite common. But if you post "anyone else here keep forgetting things?" on r/Alzheimers obviously people on there are going to be like "yeah me too".

I am not sure what your point is. Mine is precisely that there is no clear definition nor diagnostic criteria for ADHD, and that merely having more than an average collection of these otherwise ordinary behaviors, does not automatically constitute a new neurological disorder.

What I was trying to demonstrate is that people DO have the belief that ADHD is a causative thing in itself, and not merely a name for a collection of symptoms used to make treatment easier, as was suggested is the case.
