Forty seven children were followed up for one year, after their first epileptic seizure, without treatment. Six patients (12,8°,/o) had a second episode, in five of them the fust crisis been tonic and generalized, in one been a typical Grand Mai convulsion; in three of this cases the second episode had the same clinical pattern than the first one. The age of onset seems not to have any predictive value. EEC records showed slow and paroxistic electric patterns in those children with a second seizure.Cuando un enfermo presenta por primera vez una crisis epileptica, se plantea al medico el importante desafio de si se debe o no recomendar un tratamiento antiepileptico. La decision deberia estar basada en el conocimiento del pronostico de la crisis y de los factores predictores de recurrencia de nuevos episodios.

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. (
