We will never rename ADHD because of laws. ADHD is a bad name, but the laws that help or protect those who have the condition would lose all of that the moment they stopped having ADHD and had a better label for the same condition. Unfortunately the laws and protections are for the label not the condition

ADHD is both overdiagnosed and underdiagnosed, but I suspect that neither will be helped by renaming to ADH. Perhaps we should just normalize encouraging kindergarteners experiencing difficulty to spend an extra year there, whether they're just a little young or neurodivergent or both. We're the ones who stigmatize that, and it affects more than just ADHD kids.
