Lower attention ability in adolescence can predict substance use in young adulthood

The study, undertaken by researchers in Trinity's School of Psychology and School of Medicine, suggests that sustained attention and associated brain activity could be used as early biomarkers for vulnerability to substance use. The research involved the analysis of brain imaging data from over 1,000 participants in the IMAGEN study, obtained at ages 14, 19, and 23 years.

"By identifying lower sustained attention as a predictor of substance use, our findings can potentially guide the development of targeted educational programmes and cognitive training interventions to improve attention in adolescents identified as vulnerable to substance use. This proactive approach could reduce substance abuse risks, improve individual lives, and lessen societal burdens related to addiction."
