AbstractSecondary epilepsy is a common concomitant disease of viral encephalitis (VE) in children. However, the risk factors for secondary epilepsy after VE remain debated. The aim of this study was to perform a 10-year single-center retrospective analysis to investigate the incidence and risk factors of secondary epilepsy after VE in children. A total of 8691 patients suffered from VE in our hospital between December 2011 and February 2022 were included. The patients were divided into control group (Group C) and epilepsy group (Group E) according to whether they followed secondary epilepsy. Information about treatment process was collected from medical records to determine the incidence. Univariate analysis and multivariate logistic regression analysis were performed to identify the independent risk factors. In the current study, the occurrence of secondary epilepsy after VE in pediatric patients was 10.99% (385 of 3503). The results of univariate and multivariate analysis showed that unconsciousness, convulsions, times of epilepsy >2, epileptiform discharge of Electroencephalogram (EEG), and cortical and subcortical damage of magnetic resonance imaging/computer tomography were the significant risk factors for secondary epilepsy after VE. Nearly one tenth of pediatric patients suffered from secondary epilepsy after VE. Interventions for identified risk factors should be used to prevent the occurrence of secondary epilepsy.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
