Research from the University of Rochester suggests adolescents exhibiting problematic gaming behaviours show reduced activity in the brain’s reward system, highlighting potential neurological factors behind gaming vulnerabilities.
Researchers at the University of Rochester have found that teenagers who showed stronger signs of problematic gaming tended to have lower activity in the brain’s caudate nucleus when anticipating a reward, adding to evidence that differences in reward processing may help explain why some young people become more drawn to games. The study, published in the Journal of Behavioral Addictions, analysed data from the NIH-backed Adolescent Brain Cognitive Development study and followed 6,143 adolescents aged 10 to 15 over several years.
But the findings do not amount to a clinical diagnosis, and the researchers were careful not to oversell the result. The team used a six-question self-report measure, the Video Game Addiction Questionnaire, to capture symptoms of gaming addiction rather than Gaming Disorder itself, and it did not apply a clinical threshold to label participants as disordered gamers. That distinction matters: a symptom score is not the same as a diagnosis, and the study’s design can show association, not cause and effect.
The result fits with a wider body of research suggesting that adolescents with attention and self-regulation difficulties may also be more vulnerable to problematic gaming. A separate study in Frontiers in Psychology found that adolescents with ADHD were more likely to show problematic gaming patterns, while research in Entertainment Computing reported a link between ADHD symptoms, internet gaming disorder and greater spending on in-game purchases among university students. Those studies, however, do not prove that ADHD causes gaming problems or that gaming causes attention difficulties in school.
John Foxe of the Del Monte Institute for Neuroscience said the findings offer only early clues about how the adolescent brain responds to reward, while also underscoring a practical question for families: how much gaming is too much? That question has become more pressing as the gaming market continues to expand, with companies and studios increasingly using live operations, in-game purchases and other engagement tools to keep players active after launch. Still, the Rochester research does not directly explain classroom focus or academic performance, and any link between reward circuitry and school effort remains a hypothesis rather than a demonstrated mechanism.
