Screen Time in Tweens Predicts ADHD, Slower Brain Growth
Researchers tracked children’s digital habits and brain development to uncover how screen time affects ADHD symptoms.
Heavy screen use predicted a meaningful rise in ADHD severity two years later, and MRI scans showed structural differences—including reduced cortical volume and altered development in attention-related regions.
These brain measures partially explained why high screen exposure was linked to more behavioral symptoms.
The results highlight the need for thoughtful limits around screen time during crucial developmental windows.
