When I saw this comment this morning I was a little surprised, and I second guessed my own familiarity with my own brain. So I did what I do when challenged on the facts and did more reading. It’s not ambiguous. ADHD is directly related to dopamine (reception/production) deficiency. Medicating ADHD improves dopamine uptake (and production depending on the meds), and that chemical regulation relieves ADHD symptoms. It’s a small but perfectly reasonable stretch to infer that behavioral coping strategies that produce reward experiences which also relieve symptoms are likely producing similar chemical outcomes.
