The aging of the US population and the substantial rates of depression among the elderly population both attest to the public health significance of depression in old age. It complicates medical illnesses and their management, increasing disability, mortality, and health care use.1 Moreover, it can be difficult to treat to remission. Unless prevention strategies are developed, depression in old age will increasingly erode health-related quality of life and drain health care resources.
