As the percentage of U.S. adults older than 65 years continues to grow, so too does the need for preventing mental illness among older adults as well as improving clinical services and outcomes for older patients with psychiatric disorders. Psychiatry's obligation to treat this population, and an agenda for research and enhancement of clinical services, is outlined by Warren D. Taylor, M.D., M.H.Sc., James G. Blakemore Professor of Psychiatry and Director, Division of General Psychiatry, and Charles F. Reynolds III, M.D., of the University of Pittsburgh in an article published in JAMA Psychiatry.
