You’re off by a little bit: it’s not a chemical imbalance but an actual neurological difference. ADHD develops when the brain is very young and results in permanent differences in cognition and executive function.

We do use dopamine (via stimulants) to treat it, though. We essentially flood the brain with excess dopamine and hope that it’s enough to overcome the deficits caused by developmental differences.
