To determine the distribution of various epilepsies and epileptic syndromes in the epileptic population treated in a university hospital in a developing country.
Data concerning 2,531 patients with epilepsy seen between January 1989 and June 1994 were analyzed using the International League Against Epilepsy (ILAE) classification.
Of 2,531 cases, 48% fell into ILAE categories 1.3,3.2, or 4.1 (cryptogenic, without unequivocal generalized or focal seizures : or situation-related seizures, respectively).
Localization-related epilepsies (LREs) and epileptic syndromes (1.1,1.2,1.3) were found in 1,591 (62.9%) patients ; of these patients, symptomatic localization-related epilepsies totaled 62.7%, and idiopathic localization-related epilepsies accounted for only 0.7%. Juvenile myoclonic epilepsy was the most common type of idiopathic generalized epilepsy (IGE), comprising 4.9% of the total study population and 7.7% of patients registered in the epilepsy clinic.
A combination of childhood and juvenile absence epilepsies were found in only 0.4% of the total study population.
Single computed tomography (CT) enhancing lesion (SCTEL) and focal cerebral calcification (FCC) accounted for 22% of the etiologic factors for localization-related epilepsies.
Neurologic deficits were found in 9.5% of patients with SCTEL ; none were found with FCC.
None of the patients with these lesions had any history of antecedent events that suggested CNS involvement. (...)
