What New Research Says About Screen Time & ADHD (And Why Online Advice Gets It Wrong)

In this episode, Ryan and Mike discuss how screen time impacts the executive functioning skills already delayed in kids with ADHD — things like impulse control, attention shifting, and cognitive flexibility. They challenge the popular online messaging that frames screens as "social" or "regulating" for neurodivergent kids, arguing that these messages make parents feel better but don't actually build skills in children. They also cover practical advice for managing school-issued devices, why parents don't need their child's buy-in to set screen limits, and why short-term calm from screens comes at the cost of long-term development.
