This second edition reviews the history of diagnosis in psychiatry, emphasizing the limitations for classification of our current lack of knowledge of the causes of most mental disorders. It emphasizes that, in the absence of biomarkers, current categories can only be considered provisional. It takes a critical look at schema for spectra and dimensionalization of diagnosis, examines the borders between normality and psychopathology, and discusses the problem of clinical utility. The book has chapters on all the major diagnoses in psychiatry, in which the main problems of diagnosis are addressed, and in which all changes in DSM-5 are described.
