Mental disorders are highly prevalent in the primary care setting, yet are frequently misdiagnosed and often inappropriately treated. The presence of unrecognized or misdiagnosed mental disorders is associated with increased service utilization and health care costs, and can significantly impact the patient’s quality of life and risk of suicide. Mental Disorders in Primary Care offers readers with a comprehensive and evidence-based guide to the diagnosis and treatment of mental disorders in the primary care setting. This book contains 21 chapters on a variety of psychiatric disorders, such as depressive disorders and substance use disorders, and key topics for discussion such as drug interactions and psychotherapeutic interventions.
