According to this, stimulant use if anything normalizes the differences found. Without a proper understanding of the field, I have to admit its hard to criticize the specifics. https://ajp.psychiatryonline.org/doi/full/10.1176/appi.ajp.2011.11020281 https://ajp.psychiatryonline.org/doi/full/10.1176/appi.ajp.2... That said, all these studies are done way after ADHD was established. That is, ADHD as a concept wasn't established by looking at neurological brain scans or any kind of physical evidence. Makes me wonder what the exact thought process was for establishing the DSM. I still feel like if I made up a disorder by coming up with 9 semi-normal behaviors as symptoms, enough people would just by chance meet most of the criteria, and imaging scans would find some difference. Wish I was rich so I could conduct that experiment myself.
