Social Media Shrinks Kids' Brains?
17 Apr
Summary
- Children aged 10-13 with higher social media use showed thinner cerebral cortex areas.
- The study analyzed data from 7,614 US children aged 10-13.
- Thinning occurred in brain regions linked to attention, self-control, and vision.
New research indicates that children aged 10 to 13 who spend more time on social media may exhibit thinner areas of their cerebral cortex. This observation stems from an analysis of data collected from 7,614 U.S. children as part of the Adolescent Brain Cognitive Development Study.
The study found that increased daily social media engagement was associated with lower overall cortical thickness and volume. These structural differences were particularly noted in the prefrontal, temporal, occipital, and parietal lobes. These regions are crucial for functions including decision-making, attention, and processing visual information.
While the findings highlight a correlation, researchers noted that it's unclear whether social media use causes these brain differences or if pre-existing factors contribute. Future research will involve tracking these participants over several years to monitor brain development over time.
