That's an oversimplification of ADHD. The "insufficient" dopamine is extremely contextual; more accurately, dopamine is dysregulated. By suggesting that dopamine itself is a cause, which I think you are suggesting, then that's like saying the a cause of ADHD is a lack of attention. The question for ADHD should be whether abstaining from dopamine-stimulating activities does anything to correct that dysregulation and, barring some evidence I've yet to research, I don't think the answer is obvious or self-evident. Besides that potentially fallacious point I made, I don't think the ADHD brain is really relevant to whether dopamine fasting is beneficial for other brains than those with ADHD.
