In order to accurately describe and diagnose psychiatric illness, practitioners require in-depth knowledge of the signs and symptoms of behavioral disorders. Descriptive Psychopathology provides a broad review of the psychopathology of psychiatric illness, beyond the limitations of the DSM and ICD criteria. Beginning with a discussion of the background to psychiatric classification, the authors explore the problems and limitations of current diagnostic systems. The following chapters then present the principles of psychiatric examination and diagnosis, described with accompanying patient vignettes and summary tables, and related to different diagnostic concerns. A thought-provoking conclusion proposes a restructuring of psychiatric classification based on the psychopathology literature and its validating data. Written for psychiatry and neurology residents, as well as clinical psychologists, it is invaluable to anyone who accepts the responsibility for the care of patients with behavioral syndromes.
