The last line is logically ambiguous. In Europe, I believe in 2019, they found two effects: a significant _underdiagnosis_, offset by a tiny over diagnosis; now you could argue phones and screens artificially raise the genetic baseline, or that America is inherently different. But I will tell you ADHD meds calm me down, or when measured with a heart strap monitor over a full day fairly meaningfully lower my heart rate.

It’s perhaps a meme now that adhd is over diagnosed, but I’d guess the majority is pill seeking individuals looking to compete at school or at work and less false positive diagnoses such as yours.

Net net you seem to have solved it fairly quickly so at least that’s good: even when you get the diagnosis wrong if you can backtrack without significant cost then maybe it’s not absolutely horrible.
