Psychiatric problems in children have been classified as neurotic, psychotic, behaviour and development disorders and as problems due to cerebral dysfunction. Neurotic disorders include anxiety states, disorders of sleep and appetite, learning difficulties, school phobia and hysterical reactions. Psychotic disorders include infantile autism and childhood schizophrenia. Behaviour disorder takes the form of various antisocial activities, while development disorders comprise disorders of communication and specific learning and disorders of bladder and bowel control. Cerebral palsy, hyperkinetic syndrome and epilepsy are some common problems caused by cerebral disfunction.
