> ...but I want to push back on the insinuation (if I understood you correctly) that ADHD or its treatments are any less legitimate because we haven't yet figured out if we can use brain imaging to diagnose and measure treatment efficacy.

I was playing devil's advocate to explain why someone might feel that way. My personal opinion is that every adult should have the right to assess for themselves whether they feel stimulants can improve their quality of life. The question of whether ADHD is "real" or legitimate is totally unimportant to me. And I agree with your take: if we can identify symptoms and effectively treat them, that is more important than uncovering some underlying "legitimacy" of the treated condition.

Congratulations on getting diagnosed. ADHD has the highest treatment success rate among psychiatric conditions. Be sure to keep up with all the other healthy habits for improving focus (sleep, exercise, nutrition, hydration, etc.).
