This Shorter Oxford Textbook of Psychiatry succeeds the Oxford Textbook of Psychiatry, third edition (1996). It continues in the tradition of providing clear, comprehensive and practical coverage of clinical psychiatry specifically tailored to the needs of trainees, as well as providing a useful reference work for psychiatrists in practice and general practitioners. This new edition has been extensively revised and updated with the help of a team of expert advisors. The revision pays particular attention to the considerable advances in knowledge derived from the field of neuroscience, as well as emphasizing an evidence-based approach to practice and attention to ethical issues. In addition, there are new chapters on somatoform and dissociative disorders, neuropsychiatry and sleep disorders and eating disorders. The text and layout have been redesigned with greater use of illustrations, tables, lists and summary boxes, and the comprehensive reference section has been brought right up to date.
