Evolutionary Psychiatry was first published in 1996, the second edition followed in 2000. This ground breaking book challenged the medical model which supplied few effective answers to long-standing conundrums. A comprehensive introduction to the science of Darwinian Psychiatry, the second edition included important fresh material on a number of disorders, along with a chapter on research. Anthony Stevens and John Price argue that psychiatric symptoms are manifestations of ancient adaptive strategies which are no longer necessarily appropriate but which can best be understood and treated in an evolutionary and developmental context. Particularly important are the theories Stevens and Price propose to account for the worldwide existence of mood disorders and schizophrenia, as well as offering solutions for such puzzles as paedophilia, sado-masochism and the function of dreams. Readily accessible to both the specialist and non-specialist reader, Evolutionary Psychiatry describes in detail the disorders and conditions commonly encountered in psychiatric practice and shows how evolutionary theory can account for their biological origins and functional nature. This Classic Edition of the book includes a new preface by Anthony Stevens and a foreword by Paul Gilbert.

A founder of the field of evolutionary medicine uses his decades of experience as a psychiatrist to provide a much-needed new framework for making sense of mental illness. Why do I feel bad? There is real power in understanding our bad feelings. With his classic Why We Get Sick, Dr. Randolph Nesse helped to establish the field of evolutionary medicine. Now he returns with a book that transforms our understanding of mental disorders by exploring a fundamentally new question. Instead of asking why certain people suffer from mental illness, Nesse asks why natural selection has left us all with fragile minds. Drawing on revealing stories from his own clinical practice and insights from evolutionary biology, Nesse shows how negative emotions are useful in certain situations, yet can become overwhelming. Anxiety protects us from harm in the face of danger, but false alarms are inevitable. Low moods prevent us from wasting effort in pursuit of unreachable goals, but they often escalate into pathological depression. Other mental disorders, such as addiction and anorexia, result from the mismatch between modern environment and our ancient human past. And there are good evolutionary reasons for sexual disorders and for why genes for schizophrenia persist. Taken together, these and many more insights help to explain the pervasiveness of human suffering, and show us new paths for relieving it by understanding individuals as individuals.

This book is unique in taking an evolutionary perspective to understanding psychiatric and psychosomatic conditions. It explores how the human brain/mind has been shaped by natural and sexual selection and why adaptations to environmental conditions in our evolutionary past may not always work in our best interests.

For years, psychiatry has operated without a unified theory of behavior; instead, it has spawned a pluralism of approaches--including biomedical, psychoanalytic, behavioral, and sociocultural models--each with radically different explanations for various clinical disorders. In Darwinian Psychiatry, Michael T. McGuire and Alfonso Troisi provide a conceptual framework for integrating many features of prevailing models. Based on Darwinian theory rather than traditional approaches, the book offers clinicians a fundamentally new perspective for looking at the etiology, pathogenesis, diagnosis, and treatment of psychiatric disorders. Writing from this innovative theoretical position, the authors discuss the origin of pathological conditions, the adaptation of symptoms and syndromes, the biological basis of social relations, and many other key concepts. This groundbreaking book will introduce those who study and are involved in the alleviation of mental suffering to an approach that will lead to radical changes in clinical practice. The authors suggest that when making diagnostic assessments, psychiatrists should evaluate not only the patients' symptoms but also their functional capacities, and that therapeutic interventions should work toward the achievement of biological goals. Providing an essential framework for understanding both everyday human behavior and a range of mental disorders, Darwinian Psychiatry will appeal to all mental health professionals and general readers interested in human psychology and behavior.

This book examines human psychology and behavior through the lens of modern evolutionary psychology. Evolutionary Psychology: The Ne w Science of the Mind, 5/e provides students with the conceptual tools of evolutionary psychology, and applies them to empirical research on the human mind. Content topics are logically arrayed, starting with challenges of survival, mating, parenting, and kinship; and then progressing to challenges of group living, including cooperation, aggression, sexual conflict, and status, prestige, and social hierarchies. Students gain a deep understanding of applying evolutionary psychology to their own lives and all the people they interact with.

Mental disorders arise from neural and psychological mechanisms that have been built and shaped by natural selection across our evolutionary history. Looking at psychopathology through the lens of evolution is the only way to understand the deeper nature of mental disorders and turn a mass of behavioral, genetic, and neurobiological findings into a coherent, theoretically grounded discipline. The rise of evolutionary psychopathology is part of an exciting scientific movement in psychology and medicine -- a movement that is fundamentally transforming the way we think about health and disease. Evolutionary Psychopathology takes steps toward a unified approach to psychopathology, using the concepts of life history theory -- a biological account of how individual differences in development, physiology and behavior arise from tradeoffs in survival and reproduction -- to build an integrative framework for mental disorders. This book reviews existing evolutionary models of specific conditions and connects them in a broader perspective, with the goal of explaining the large-scale patterns of risk and comorbidity that characterize psychopathology. Using the life history framework allows for a seamless integration of mental disorders with normative individual differences in personality and cognition, and offers new conceptual tools for the analysis of developmental, genetic, and neurobiological data. The concepts presented in Evolutionary Psychopathology are used to derive a new taxonomy of mental disorders, the Fast-Slow-Defense (FSD) model. The FSD model is the first classification system explicitly based on evolutionary concepts, a biologically grounded alternative to transdiagnostic models. The book reviews a wide range of common mental disorders, discusses their classification in the FSD model, and identifies functional subtypes within existing diagnostic categories.

This text explores the relationship between evolutionary theory and philosophy of psychiatry. In particular, it discusses a number of reasons why philosophers of psychiatry should take an interest in evolutionary explanations of mental disorders, and more generally, in evolutionary thinking.
