This Tuesday a study was published in JAMA suggesting that frequent use of digital media by adolescents might increase their odds of developing symptoms of attention deficit hyperactivity disorder (ADHD). NPR covered the story noting that this is one of the first stories to look at modern digital media and ADHD risk. Previous studies found impacts of video games and television on teenagers as slightly higher risk of developing ADHD behaviors, however it had never been documented, longitudinally, the impacts of digital media devices on teens.
Per the NPR article, "The study followed 2,587 10th graders in schools in Los Angeles county over two years. The teens showed no symptoms of ADHD at the beginning of the study. By the end, teens with more frequent digital media use were more likely to have symptoms of ADHD." The study author notes that nearly 10% of the children who were high frequency users, showed symptoms of ADHD.
