ADHD is related to some dopamine dysfunctions which a decent proportion of people correct for with aggression[1] - I think predominantly men do this - since conflict will supply the reward response our brains should have given out for success. So a lot of confrontational people that have un-diagnosed ADHD will actually level out with medication.
1. Sort of a vast simplification, but basically hulking out and raging - maybe physically, maybe passive aggressively, maybe verbally - the form it takes varies wildly.
Yes, this is pretty spot on. In my specific case, most of the aggression gets channeled toward my work and makes me good at what I do. The stimulants (pushed on me by multiple doctors) almost ruined my career, and my life, in more ways than one! Took years away from me. Any other aggression that happens to be there is just a part of who I am, and taking that away is a bug, not a feature. The side effects and danger that comes with any of those drugs is not worth it in many cases.
