That comment makes me wonder if the school understands what hyperfocus looks like. Not even sure how a med could cause it. I am trying to recall all the times and what I am coming up with is never have any of my family hyperfocused while on our meds, really, never.
Ritalin does make you zombie like, at least that was the complaint of my older kids and their teachers. So far as I know that is the only med that does this. When Adderall came out they switched to that are were much happier. They are now in the mid to late 20s so there was just Ritalin when they were in grade school.
I cannot even think of a task at school that would cause hyperfocus at his age. Just guessing here, is he having issues with transitioning? Is that what they think is hyperfocus because he doesn't want to stop a task? My younger son had a hard time transitioning but that wasn't the ADHD that was his Autism.
I hope this helped a bit though I feel kind of like I am stabbing in the dark.
