Newly revised and updated, this is the definitive reference work on psychiatric terminology. It encompasses new information that has arisen from research advances, social changes, legal developments, and educational innovations since the appearance of the fifth edition in 1981. Many new terms have been added from the study of agoraphobia and panic disorder; sleep, speech, and eating disorders; depression; disorders in cognitive functioning; and particularly from neuroscience and psychopharmacology. In addition, the nomenclature of the recently revised third edition of the Diagnostic and Statistical Manual of the American Psychiatric Association has been incorporated. The result is an authoritative reference that offers encyclopedic, up-to-date coverage of all areas of psychiatric interest. Called "by far the best and most complete dictionary devoted to this subject" (Psychiatric Quarterly on a previous edition), this new edition will be welcomed by all professionals and students in the field of mental health.
