This updated resource refines and expands on both the core concepts and the real-world practice of consultation-liaison psychiatry in medical settings. New and revised chapters provide background and basics and describe CL psychiatry approaches to managing a wide array of common conditions, including heart disease, dementia, anxiety and depressive disorders, alcohol and substance use problems, and chronic pain. Besides the fine points of practice in varied chronic and acute care settings, specific patient populations such as children, elders, ob/gyn patients, and the immunocompromised are discussed. The latest information and insights on pharmacology, interviewing, and ethical and cultural issues round out the book's highly accessible coverage.
