Depression is a poorly used term and is often not diagnosed when it should be, or diagnosed and treated when it shouldn't. Clinicians face a wide range of presentations, and the challenge of delineating true depression from normal human responses to difficult situations; they then have to decide the best course of treatment. 'Fast Facts: Depression' will help health professionals to navigate the complexities of diagnosing and managing this common condition. It provides concise and clear descriptions of the features, identification and management of depression as well as the wider context of cause, prevention, and cost. The 4th edition of 'Fast Facts: Depression' has been fully updated using the DSM-5 diagnostic criteria and the latest recommendations from research reviews and clinical practice guidelines, and includes a new chapter on depression in women. It is ideal for healthcare professionals working in primary care and specialist medical centers, and is ideal for anyone who wants to better understand depression as both an international public health problem and a common clinical mental health disorder.
