We investigated familiarity with, knowledge of, and attitudes toward epilepsy among teachers in elementary schools in Korea, where there is profound prejudice against epilepsy. Most of the teachers thought that epilepsy is a genetic disease. They agreed that children with epilepsy (CWE) should attend regular classes (although with some restriction of school activities) because their academic achievement would be comparable to that of children without epilepsy. However, half of the teachers opposed having CWE in their own classes because they feared a child having a seizure during class and they felt they lacked knowledge of first-aid for seizures. Those teachers who had inaccurate clinical knowledge of epilepsy also demonstrated negative attitudes toward the marriage and employment of persons with epilepsy. We conclude that information about epilepsy should be included in teacher training programs so as to increase their level of knowledge of epilepsy and correct prejudices against epilepsy.
