This book illustrates the imperative for late-life depression prevention. It introduces a broad range of approaches to prevention, and provides detailed examples of clinical and research applications of late-life depression prevention - all with consideration of medical and scientific, social, economic and global health perspectives.  Current guidelines and tools for assessing depressive disorders among older adults are discussed, with a view toward applications for prevention. Written by experts in the field, this text also considers policy and economic implications for preventing late-life depression, such as  the many complicating conditions - such as diabetes, hypertension or heart disease - that may co-occur with depression among older adults and that may incur higher total healthcare costs.   Prevention of Late-Life Depression: Current Clinical Challenges and Priorities is an important new volume that will be useful to all providers that are concerned with the mental health of our rapidly expanding aged population.
