This new, and heavily revised, edition of Psychopharmacology, provides a comprehensive scientific study of the effects of drugs on the mind and behavior. With the growing prevalence of psychiatric and behavioral disorders and the rapid advances in the development of new drug therapies, this textbook offers an essential understanding of the necessary details of drug action.The book presents its coverage in the context of the behavioral disorders they are designed to treat, rather than by traditional drug classifications, to strengthen understanding of the underlying physiology and neurochemistry, as well as the approaches to treatment. Each disorder from the major diagnostic categories is discussed from a historical context along with diagnostic criteria and descriptions of typical cases. In addition, what we presently know about the underlying pathology of each disorder is carefully described. Providing a solid foundation in psychology, neuroanatomy and physiology, the book also offers a critical examination of drug claims, as well as coverage of evidence-based alternatives to traditional drug therapies. Throughout, this text discusses how drug effectiveness is measured in both human and animal studies.Topics new to this edition include: a stronger emphasis on the environmental impacts on drug effectiveness; more on the mechanisms of adverse reactions to drugs and information on managing drug side effects; the risks and benefits of using mood stabilizing drugs to address behavior in youth with ADHD or ASD; and discussion of the research-to-practice gap in pharmacological care for children and adolescents.Accompanied by a robust selection of support material, this textbook is ideal for undergraduate and pre-professional students on courses in Psychopharmacology, Clinical Psychopharmacology, Drugs and Behavior. It is a valuable contribution to highlight the symbiotic relationship between psychopharmacology and the neural and behavioral sciences.
