Psychotic Disorders: Comprehensive Conceptualization and Treatments emphasizes a dimensional approach to psychosis-one of the most fascinating manifestations of altered brain behavior-that cuts across a broad array of psychiatric diagnoses from schizophrenia to affective psychosis and organic disorders like epilepsy and dementias. Written by an international roster of over seventy leading experts in the field, this volume comprehensively reviews, critiques, and integrates available knowledge on the etiology, mechanisms, and treatments of psychotic disorders, and outlines ways forward in both research and clinical practice towards more objective, mechanistically-based definitions of psychotic disorders. Chapters address topics such as psychosis phenomenology, biomarkers and treatments, the overlaps and interfaces between psychiatric disorders within the psychosis dimension, and novel disease definitions. Furthermore, the volume incorporates findings on potential mechanisms, bridges between various system levels (i.e., genetic, epigenetic, molecular and cellular, brain circuit and function, psychological, social, environmental and cultural) and their interactions, as well as the potential role in causation and/or mediation in psychotic disorders. Finally, the volume outlines a broad array of treatment approaches, from the readily available (e.g., psychopharmacology, various modalities of psychotherapy) to the experimental (e.g., cognitive interventions, neuromodulation). With a concluding section of forward perspectives conjecturing future directions and related challenges, this book aspires to stimulate new knowledge, generate novel frameworks, and carry new directions forward on psychotic disorders.

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 2013.

Deconstructing Psychosis: Refining the Research Agenda for DSM-V examines the current evidence regarding the diagnosis and pathophysiology of common psychotic syndromes including: - Schizophrenia- Bipolar disorder- Major depressive psychosis- Substance-induced psychosis

It also addresses broad issues relating to diagnosis such as the ways in which psychosis cuts across multiple diagnostic categories. Beyond merely summarizing the current state of the science, the authors of these papers critique the current research and clinical evidence, and raise questions about gaps in our knowledge.

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.

In the learned editors' selection of papers for inclusion in this volume, they have exhibited their conviction that DSM-V is a "living document" that will reflect the pace of progress in multiple areas, ranging from molecular genetics and brain imaging to social, behavioral, and anthropological science.

As a book on the narrowly defined topic of linking the classification of psychotic syndromes with their underlying pathophysiology and potential etiology, there is no other writing of comparable content available today.
