Abstract:
To describe the first unprovoked seizure in typically developing children, its clinical characteristics, recurrence rate, and possible risk factors in a real-life setting in Southern Brazil. Method In this retrospective cohort study, medical records of typically developing children aged 28 days to 14 years who had a first unprovoked seizure in a single tertiary care center were reviewed, in a 10-year period (2006-2016). Results Seventy-four children were included, 41 males and 33 females. The most frequent age group of the first seizure was 5 to 10 years and seizure main type was focal (50%). Most seizures occurred while children were awake (70%). All patients underwent an electroencephalogram (EEG), which was normal in 44.6%. Neuroimaging was performed in 81%, in 2 cases the etiology was considered structural, the remaining was classified as unknown. Median follow-up period was 32.5 months. Seizure recurrence rate was 56.7% and age younger than 5 years was a possible risk factor. Interpretation In the subpopulation of Brazilian typically developing children with a first unprovoked epileptic seizure there is a high recurrence rate. An abnormal EEG was a common finding, although it was not associated with a higher risk of seizure recurrence. A possible risk factor was age younger than 5 years, which may suggest a more rigorous follow-up of these patients.
