Risk of Epilepsy in Children Presenting to Emergency Departments with Their First Afebrile Seizure

Seizure is one of the most common neurologic disorders in pediatric emergency department visits. Early detection of epilepsy development in children with afebrile seizures is important. We identified predictors of epilepsy development in children with their first afebrile seizure. In this retrospective multicenter study, we enrolled pediatric patients aged 1 month to 18 years who presented with afebrile seizures at the emergency department from January 2017 to December 2020. Multivariable logistic regression analysis was performed to identify factors associated with epilepsy development. A total of 417 pediatric patients were enrolled, 161 (38.6%) of whom developed epilepsy. From the multivariable logistic regression analysis, older age at onset (2−5 years, odds ratio [OR] 2.611, p = 0.010; 11−15 years, OR 3.138, p = 0.003; 16−18 years, OR 4.292, p = 0.002), longer seizure duration of more than 10 min (OR 4.869, p = 0.006), two or more seizures (OR 2.378, p = 0.004), lethargy (OR 2.341, p = 0.021), and a lactate level > 2.27 mg/dL (OR 4.205, p < 0.001) were significant predictors for the development of epilepsy in children experiencing their first afebrile seizure
