Teen mental health crises are rising — but what if providers could intervene before symptoms fully take hold? In this conversation, Duke University School of Medicine's Jonathan Posner, M.D., professor of psychiatry and behavioral sciences, and Matthew Engelhard, M.D., P.h.D., assistant professor of the Department of Biostatistics and Bioinformatics, break down the "Duke PMA" — an AI-powered predictive model designed to identify adolescents at high risk for psychiatric illness. They explore how sleep, device use, and a myriad of other factors shape mental health risk, and how this technology could transform prevention, especially in underserved communities.
