Neuropsychiatry is a rapidly expanding field, linking the traditional areas of neurology and psychiatry, which has benefited greatly from recognition of the role of genetic and environmental determinants of psychiatric disorder particularly in childhood and adolescence. Based on twenty years of clinical experience and eighteen years of research, Professor Gillberg has utilised his unique and detailed interdisciplinary knowledge of neurobiology, pharmacology, epidemiology and neuropsychology to compile this comprehensive reference to clinical assessment and treatment of the many neuropsychiatric disorders of childhood which, at a conservative estimate, affect five in every hundred children. This is valuable reference resource that is sure to be welcomed by a wide range of professionals and researchers including child neurologists, psychiatrists, psychologists, speech therapists and special education teachers.
