"Deconstructing Psychosis: Refining the Research Agenda for DSM-V" provides an all-important summary of the latest research about the diagnosis and pathophysiology of psychosis. This volume gives the reader an inside look at how psychotic phenomena are represented in the current diagnostic system and how DSM-V might better address the needs of patients with such disorders. The book presents a selection of papers reporting the proceedings of a conference titled 'Deconstructing Psychosis' convened by the American Psychiatric Association (APA) in collaboration with the World Health Organization (WHO) and the U.S. National Institutes of Health (NIH). The conference was designed to be a key element in the multiphase research review process for the fifth revision of "DSM". This book is one in a series of ten that reflects some of the most current and critical examinations of psychiatric disorders and psychotic syndromes. APA published the fourth edition of "DSM" in 1994 and a text revision in 2000. "DSM-V" is scheduled for publication in 2012. The book provides recommendations for the most promising areas of research in psychosis, which may lead to more refined treatments based on a better understanding of what biological and environmental factors contribute to its development and symptoms.
