"Psychiatry and Psychosomatic Medicine are concerned with medical conditions affecting brain, mind and behaviour in manifold ways. Traditional approaches have focused on a restricted array of potential causes of psychiatric and psychosomatic conditions - including adverse experiences such as trauma, neglect or abuse, genetic vulnerability and epigenetic regulation of gene expression. Whilst essential for the understanding of mental disorders, these approaches have disregarded important questions such as why the human mind is vulnerable to dysfunction at all. The Textbook of Evolutionary Psychiatry and Psychosomatic Medicine updates and expands on the original Textbook of Evolutionary Psychiatry (OUP, 2008) to provide answers to these questions by emphasising an evolutionary perspective on psychiatric and psychosomatic conditions. It explains how the human brain/mind has been shaped by natural and sexual selection; why adaptations to environmental conditions in our evolutionary past may nowadays work in suboptimal ways; and how human cognition, emotions, and behaviour can be scientifically framed to improve our understanding of how people try to attain important biosocial goals pertaining to one's status in society, mating, eliciting and providing care, and maintaining rewarding relationships."--Publisher's description.
