Study: Kids’ Screen Time Changes Struture Of The Brain

 Early results from an ongoing study funded by the National Institute of Health show that using smartphones, tables and video games is physically changing the brains of adolescents, according to a report on CBS’ 60 Minutes. The study is following more than 11,000 nine- to 10-year-olds for a decade to see how childhood experiences impact the brain and affect emotional development and mental health. The early results from brain scans are showing that more than seven hours of daily screen use leads to premature thinning of the brain cortex, the outermost layer that processes information from the physical world. However, study director Gaya Dowling cautioned, “We don’t know if it’s being caused by the screen time. We don’t know if it’s a bad thing.” She said, “It won’t be until we follow them over time that we will see if there are outcomes that are associated with the differences that we’re seeing in this single snapshot.”
