There is a theory that what we consider ADHD might have naturally evolved, because it would give an evolutionary advantage for hunter-gatherers.[0] Life in the modern era is different from hunter-gatherer lifestyle and thus people with ADHD find it difficult to fit in. I don't know how true this theory is. There is some evidence for it, because ADHD is very prevalent, but at the end of the day it doesn't matter why people struggle. What matters is that they do and we have the tools to help with that. A big reason for the divide between Europe and the US in ADHD is that Europe usually uses the ICD, while the US uses the DSM. The DSM seems to be less strict about the criteria. It's probably also the case that many Europeans, particularly in former Soviet states were never tested.
