The epidemiology of epilepsy in children: a report from a Turkish pediatric neurology clinic.

This retrospective cohort study aims to assess the distribution of seizure types and epileptic syndromes in children with epilepsy who were followed up in a tertiary outpatient pediatric neurology clinic between January 2004 and December 2009. The findings of 533 children aged between 2 months and 16 years were evaluated. The International League Against Epilepsy criteria (of 1981 and 1989) were used for diagnosis and classification. The rate of partial seizures (56.5%) was higher than that of generalized seizures (43.5%). Partial seizures were more common during late childhood (P < .001). Localization-related epilepsies (53.3%) were more frequent than generalized epilepsies (37.1%). Generalized epilepsies were more frequent during the first year of life, whereas localization-related epilepsies were more common at later ages (P < .001). The majority had a symptomatic etiology (47.1%). The increased frequency of symptomatic etiologies attributed to perinatal insults suggests that intractable epilepsies during childhood represent an important health issue for developing countries.
