Great article, Howie. And thanks for shedding light on your personal experiences, Elaine. It's interesting because most of the theories I've heard concerning the link between ADHD and digital media use focus on how the symptoms of ADHD (e.g., inattentiveness, impulsivity, etc.) put a person at risk for developing problematic technology use as an unhealthy way of coping with/expressing these symptoms. However, in your son's case, it appears that his video gaming preceded his ADHD symptoms. I'm wondering if there are bidirectional influences involved. Hopefully, more research will be conducted focusing on causality.
In the interim, raising awareness about the links between problematic technology use and ADHD (as well as other types of co-occurring mental health issues) is very important, and can help inform prevention efforts.
