Psychologists, psychiatrists, social workers, psychiatric nurses, theoreticians, practitioners, and other allied professionals who together represent the entire arc of the mental health field must be versed in psychopathology, the study of mental and emotional phenomena, abnormal psychology, and specific symptoms and behaviors. To this end, Henry Kellerman has assembled the first dictionary to focus exclusively on the subject of psychopathology, featuring more than two thousand entries (over fifteen hundred primary and more than five hundred subentries) on specific symptoms and disorders, general syndromes, facets of personality structure, and diagnosis as well as sampling benchmark contributions by theoreticians and researchers covering the history of psychopathology. These contributions include those of a psychodynamic nature as well as those that reflect the domain of cognitive and behavioral approaches. The relatively new field of neuropsychoanalysis is also represented. This branch of neuroscience is concerned with the relation between the brain and mind, specifically with reference to brain architecture and function. Monitored by a distinguished editorial board, The Dictionary of Psychopathology mostly adheres to the latest DSM nomenclature, yet Kellerman also retains useful residual diagnoses of previous DSM formulations. Thus, The Dictionary of Psychopathology is constructed as a product that can broadly contribute to the synthesis of psychopathology.
