UCSF Study Links Addictive Social Media Use to Rising ADHD Symptoms in 11,000 U.S. Boys

Summary
A UCSF study of more than 11,000 U.S. adolescents found that year-to-year increases in addictive social media use were followed by higher ADHD symptoms one year later, especially among boys ages 14 and 15.
The five-year analysis, published in JAMA Network Open, did not consistently find the reverse pattern, suggesting ADHD symptoms generally did not precede heavier addictive social media behavior.
At age 12, 23% of participants said they spent a lot of time thinking about social media, 18% used it to forget problems, and 15% said they could not cut back.
Researchers said the study cannot prove causation, but argued addiction-like use patterns—not just total screen time—may matter most for parents watching for sleep, schoolwork and relationship problems.
About 7 million U.S. children ages 3 to 17 have been diagnosed with ADHD, and the study found no clear comparable link between addictive social media use and ADHD among girls.

Addictive Social Media Use Linked to 1-Year Rise in ADHD Symptoms Among Adolescent Boys: New UCSF Study and Global Policy Response
Overview
A major study from UCSF, published in July 2026, found that adolescent boys who showed signs of addictive social media use—such as constantly thinking about social media and wanting to cut back but being unable to—were more likely to develop increased ADHD symptoms over the following year. By surveying both the boys and their parents over time, the researchers revealed a strong link between addictive online habits and worsening attention issues. This research highlights a possible causal relationship, suggesting that heavy, compulsive social media use can directly contribute to mental health challenges in young people.
