Schizophrenia is one of the most severe psychiatric disorders, carrying with it significant stigma and a number of debilitating symptoms. While material on its "positive" symptoms, such as hallucinations and delusions, is readily available, its "negative" symptoms, which present heterogeneously as deficits across a variety of domains, are not nearly so well-documented and often go undiagnosed with no effective treatment. Given the poor functioning and outcomes which occur as a result of these symptoms, it is imperative they receive greater focus. Part of the Oxford Psychiatry Library (OPL) series, this concise pocketbook provides readers with a comprehensive overview of the definition, evaluation, and treatment of negative symptoms. Written by experts in the field, with key points at the beginning of each chapter for quick reference, this is an invaluable resource for any mental health care professional working with individuals affected by schizophrenia.
