A growing body of neurological research is raising fresh concerns about how extensive screen time is affecting children’s brain development, with scientists now linking heavy digital use to measurable structural changes in key areas of the brain responsible for memory, attention and emotional regulation.
In a newly released analysis of pediatric brain scans, researchers found evidence of cortical thinning—a reduction of the brain’s outer layer that plays a crucial role in cognitive processing—in children who spend long hours daily on phones, tablets, gaming devices or streaming platforms.
Experts say the findings are especially troubling because cortical thinning is associated with issues such as weakened memory, shorter attention spans, and slower information processing.
“This isn’t just about kids being distracted,” researchers explained. “We are seeing biological changes in the brain that appear connected to chronic screen exposure.”
The study examined children across various age groups, but the most striking effects were seen in younger children whose brains are still rapidly developing. Some children in the highest screen-time category showed accelerated thinning in regions linked to decision-making and impulse control.
While researchers emphasize that screen time is not inherently harmful, they warn that unrestricted or excessive use—especially without educational content or adult oversight—appears to pose the greatest risk.
Pediatric specialists are urging families to set limits, encourage more outdoor activity and prioritize in-person social interaction to help reduce potential long-term effects.
“We’re not saying eliminate screens entirely,” one pediatric neurologist clarified. “We’re saying be intentional. The developing brain is extremely sensitive.”
The findings come as schools, parents and policymakers continue debating how digital media should be incorporated—or restricted—in classrooms, homes and childcare settings.
