ADHD is not just "having trouble concentrating". It is a completely broken prioritizer, executive function deficit, and nearly non-existing ability to linearize tasks into intermediate-scale command sequences. And tons of other things, some of them good (like immediate recall of association trees, whether we like it or not; this helps if you want some original ideas), but most of them bad. About 3% of population have ADHD. And it is quite easily recognizable and distinct from just "troubles of concentration".
