This is a descriptive study, carried out on 9875 school students of 21 schools, located in El Manyal Island (Cairo) searching for students having epilepsy. During this it passed through the following stages:1-The number of schools in El Manyal area as well as their address was collected from the Ministry of Education Information Centre.2-In each school, the total number of students, their sex, and their distribution in school grades were collected from each school data records, and the medical records in the medical offices in each school.3-The data about the epileptic children (number, sex, and school grades) also collected from school medical and social files as well as the Health Insurance medical centers and hospitals for children.4-Data about age at onset, type of seizure, possible aetiology, frequency of seizures, associated conditions and antiepileptic used were collected through individual interviews with epileptic children, school medical staff, and one of the family members whenever possible.5-Prestructured questionnaires (designed on the WHO recommendations for the diagnosis of epilepsy), were applied to the known epileptic students and also were applied on random method on 1268 students, whom age ranging from 13 to 18 years, for detection of possible non reported epileptic students. It can be concluded that:1-The prevalence of epilepsy in school children is much similar to that in other countries 2-Prevalence of epilepsy is higher in boys during the school age (this may be increased exposure to accidents and trauma)3-Children during school age period have relatively well controlled epilepsy (nearly 80 % of them have a monthly seizure or less.)4-Most children were controlled by using single antiepileptic drug, and Carbamazepine was the most commonly used, and partial seizures were the commonest type.5-Prestructured questionnaires give results about having a paroxysmal disorder, which need to be ascertained by more investigations to confirm the diagnosis of epilepsy.
