Psychiatric diagnosis is indispensable to treatment, prognosis, and research in psychiatry and is used in other areas of medicine, law, education, criminal justice, the regulation of drugs by the FDA, and other arenas as well. Yet the current DSM system is a work in progress that will be altered by emerging knowledge about the causes of mental disorders, diagnostic tools such as functional MRI, and developments in neuroscience-all new since DSM-IV was issued. In Advancing DSM: Dilemmas in Psychiatric Diagnosis, leading clinicians and researchers present diagnostic dilemmas from clinical practice that are intriguing, controversial, unresolved, and remarkable in their theoretical and scientific complexity. Chapters present a specific case study of a disorder or an area of diagnosis that illuminates the need for a revised diagnostic system. Chapter by chapter, Advancing DSM raises important, clinically relevant questions about the nature of diagnosis under the current DSM system and recommends new approaches. DSM has been a landmark achievement for the field. By allowing reliable diagnosis, it has brought order out of chaos and fostered groundbreaking advances in research and clinical care. Advancing DSM updates readers on exciting changes in psychiatry today that will impact the DSM of tomorrow.
