First generalized non treated epileptic seizure: PrognosisThe first epileptic crisis of a child force physicians to therapeutic decissions involving knowledge of its evolution and prognosis. This study was aimed to delineate prognosis, throughout an at least three years long follow up, in 50 children after their fust non provoked nor treated generalized epileptic crisis, all free from known predisposing factors for recurrence. Eleven (22%) patients had a second seizure, 9 (81%) within the following 2 years after the first episode. Epilepsy among second grade relatives, age, sex, type of generalized crisis and previous morbility were not significant variables for recurrence (p > 0.05). The second sezure was similar to the first one in 1:2 patients. This report demonstrates that few recurrences can be expected in children with a first non treated epileptic seizure, if the characteristics of every patient are properly considered. (
