By the time they’re in elementary school, some kids prove to be more troublesome than others. They can’t sit still or they’re not socializing or they can’t focus enough to complete tasks that the other kids are handling well. Sounds like ADHD. But it might be that they’re just a little young for their grade.
Studies done in several countries including Iceland, Canada, Israel, Sweden and Taiwan show children who are at the young end of their grade cohort are more likely to get an ADHD diagnosis than their older classmates.
