. An epidemiological study of absence epilepsy is presented. The study comprised a series of cases from a Swedish population, aged 0–15 years, selected on the basis of EEG criteria. All children with regular and symmetrical 3 (2–4) Hz spike‐and‐slow‐wave complexes, recorded for the first time during the period 1978–1982, were included. A total of 134 children fulfilled the inclusion criteria, and of these, 108 (80.6%) had absences alone or in combination with general tonic‐clonic seizures (GTCS); 11 (8.2%) had absences combined with other seizures; 15 (11.2%) had other types of seizures only. The mean annual incidence of absence epilepsy was 7/100 000 for children aged 0–15 years. Of these, 6.3/100 000 had absences alone or in combination with GTCS. The cumulative incidence of absence epilepsy was 98/100 000. The mean age of onset was 7 years.
