This study was designed with the objective of evaluating the chance of recurrence in our area and to answer questions regarding prognostic factors capable of helping in the management of the first seizure in childhood. One hundred and thirty six children from 1 month to 12 years of age seen at the Pediatric Emergency Division of Hospital de Clínicas de Porto Alegre because of a first seizure with or without triggering factors were included in the study. The follow-up included 121 children. We concluded that family history of seizures, presence of triggering factors at first event, seizure type, seizure duration and paroxysmal electroencephalographic abnormalities were predictive factors for seizure recurrence. The recurrence in this sample was 36.36% during the study. Cumulative recurrence risks were 14.88%, 23.14%, 28.93%, 33.06% and 35.54% to 3, 6, 9, 12 and 15 months, respectively.
