To be fair, ADHD is a developmental disorder that sometimes can present as delayed development rather than halted development. I.e being behind in executive functioning development but eventually “catching up” to peers.

That said, the severity of cases is still often determined through the lens of “how well do they fit in/mask it” and not “how is their emotional/mental wellbeing”, which definitely gives the impression of kids “growing out of it”.

Well, minds are difficult, patterns are easy.
Not all doctors are going to do it the hard way, same as not all people (encompassing all professions) do it the hard way.
