The development of psychiatric disorder among schoolchildren with epilepsy.

Two groups of epileptic children, one newly diagnosed and one with chronic epilepsy, were compared with two comparable groups of diabetic children and with children in the general population in order to investigate the development of psychiatric disorder. The results confirm previous findings that children with chronic epilepsy are significantly more disturbed than children with chronic physical illness not involving the central nervous system, and than children in the general population. Children with newly diagnosed epilepsy were also significantly more disturbed than those with newly diagnosed diabetes, and than children in the general population. The rate of psychiatric disturbance was similar in the two groups of epileptic children. In both groups of epileptic children, those with focal EEG abnormalities and/or complex partial seizures were particularly vulnerable to psychiatric disturbance.
