ADHD diagnosis and treatment is also much more strictly controlled here, so diagnosis is below internationally predicted rates, treatment is about HALF predicted rate of incidence, and yet we are flooded with articles written in/about the USA where that is maybe not the case and our teachers and public swallow it hook, line and sinker. Misdiagnosis and inappropriate treatment can happen anywhere at any time, our system isn't perfect and we get mistakes here too, but you can't make a quick visit to your local Dr and have your kid put on ADHD medication because a teacher said so. Its a complex process requiring authorised specialists (and government authority every time our specialist writes a fresh script for DD). So it's super frustrating to come up against bias that's not even based on the local situation.
