> Hyperfocus can also be a side effect of stimulant medication.

This doesn't address the fact that the hyperfocus behavior is a side effect of the poor executive function and is present in unmedicated ADHD people. In fact stimulants in an ADHD brain tend to improve executive function and make hyperfocus less likely for them.

As I said before, it's not about focus at all. It's about executive function. It just manifests in ways that look like focus problems. And yes, hyperfocus is absolutely as much of a problem as completely lacking focus.
