One thing that's maybe worth looking into is gifted children, overexcitabilities and asynchronous development. It very common to misdiagnose young gifted children with ADHD, Aspergers and other behavioural disorders. This is because at a young age the symptoms are very similar and it generally requires a more indepth interview with the child to tell the differences.

This is a good article about the differences: https://www.davidsongifted.org/Search-Database/entry/A10900

That's not to say some kids aren't both. But the rush to diagnose kids, along with the relatively simplistic diagnosis process many psychologists use can lead to misdiagnosis.
