A [1]new study by researchers at the University of California at San Francisco "adds to growing research linking increased social media use to detrimental effects on attention, [2]memory and cognition," [3]reports the Washington Post :

> The study followed more than 11,000 U.S. adolescents over a period of five years, with participants first asked about their own social media use at the average age of 12, and surveyed annually through the average age of 16. Researchers found that increases in addictive social media use were followed by rising ADHD one year later — particularly among boys who reported rising addictive social media use at ages 14 and 15. This association was not found consistently in reverse, meaning that ADHD symptoms did not appear to precede higher levels of addictive social media use... "When an individual adolescent's addictive social media use score increased from one year to the next, that same adolescent tended to show an increase in ADHD symptoms in the following year...." [said Jason Nagata, lead author of the study and an associate professor of pediatrics at the University of California at San Francisco]. He urged parents to consider: "Can their kids stop if they want to? Is social media interfering with their schoolwork? Is it impairing their social relationships? Are there addiction-like symptoms, like withdrawal and relapse?"

> Approximately 7 million American children between the ages of 3 and 17 have received an ADHD diagnosis, [4]according to the Centers for Disease Control and Prevention , and boys are diagnosed with ADHD at about twice the rate of girls. The study did not find a clear link between addictive social media use and ADHD among girls, Nagata said. "Some studies do suggest that teenage boys in particular may be more sensitive to immediate reward and sensation-seeking in adolescence," he said. And social media platforms are designed to provide exactly that: "It encourages frequent task-switching, and there's this constant stream of stimulation that might make it harder for adolescents to maintain and sustain attention that is needed for schoolwork and daily life," he said. "The design features of social media offer the constant reinforcement of impulsivity — it offers immediate gratification and novelty and it encourages multitasking, which can then override working memory and executive control." Experts have long noted that this kind of digital exposure [5]is particularly significant during critical stages of mental, social-emotional and cognitive development...
