Background: There are few studies evaluating risk factors for poststroke epilepsy (PSE) after an arterial ischemic stroke (AIS) in childhood. This study aimed to evaluate clinical and radiological predictors for PSE in a cohort of children with a first-ever AIS. Methods: A retrospective analysis of a single-center prospective consecutive cohort of children beyond neonatal age with a first-ever AIS admitted at the Pontifical Catholic University of Chile's Clinical Hospital between 2003 and 2013. All participants had a brain magnetic resonance imaging at the time of diagnosis. All children underwent follow-up for at least three years with an annual dinical evaluation. We used the current epilepsy definition of the International League Against Epilepsy. Studied variables include demographics, clinical manifestations at onset, stroke risk factors, and radiological characteristics of MS. Cox proportional hazards regression analysis was used to evaluate PSE risk adjusted for dinical and radiological variables. Results: Among 98 children who met the study criteria, 41 (41.8%) with PSE. Following multivariate analysis, it was determined that the predictors of PSE include young age at AIS (hazard ratio [HR] = 0.91; confidence interval [CI] = 0.84-0.99), the occurrence of acute symptomatic seizures (HR = 329; CI = 1.35-8.01), cortical infarction (HR = 5.01; CI = 2.00-12.6), and multifocal infarction (HR = 327; CI = 1.01-10.8). Conclusion: Seizures, young age, cortical lesions, and multiple infarction at the time of stroke are independent risk factors for PSE in children following a first-ever AIS. (C) 2018 Elsevier Inc.
