The issue is, yes, there are ADHD cases that are debilitating but they typically don't even make it out of training. If you're managing the condition through therapy and potentially medication there isn't an issue but the FAA fails to recognize that neurodivergence isn't binary.
A significant chunk of the pilot population has ADHD, it's common enough to basically be a meme in the community because the career/hobby is especially appealing to those that have it.
Military isn't necessarily a good benchmark for sane ideas.
It's total nonsense and the entire aeromedical division should be razed and rebuilt from the ground up.
