Psychogenic seizures after head injury in children.

A total of 148 patients with a history of probable seizure disorder were studied prospectively with long-term video electroencephalography over a 1-year period. Sixteen (11%) were identified with psychogenic seizures. Eleven (69%) of 16 were boys, with a mean age of 10.5 years. Seven (44%) of the 16 had an antecedent history of head injury prior to the development of these episodes; of these patients 85% were boys. Our results suggest that contrary to findings in the adult population, psychogenic seizures can be commonly seen in boys. The prevalence of antecedent head injury suggests that it is a notable risk factor in children as well as adults in the occurrence of psychogenic seizures.
