This text presents a comprehensive overview of the psychopathological disorders of childhood and adolescence from a brain-based perspective. Based upon the highly respected Handbook of Pediatric Neuropsychology, this text covers all of the major pediatric disorders described in the DSM-IV-TR, while also offering hard-to-find coverage of childhood cognitive disorders that have not been addressed sufficiently in the DSM and other child psychopathology texts. Each chapter includes the etiology of each disorder (including genetics), its prevalence, clinical presentation, assessment considerations.
