The Substance Abuse and Mental Health Services Administration (SAMHSA) and Administration on Aging (AoA) commissioned a series of Issue Briefs to address behavioral health issues that are important to older Americans. The Issue Briefs identify key information and opportunities for action that can improve the lives of older people. This Issue Brief is designed to: (1) Foster the adoption of evidence-based behavioral health programs and promising practices by state and local service system leaders; and (2) Recognize essential elements of behavioral health practices that support sustainability of services.
