FACTORS ASSOCIATED WITH SUBSEQUENT EPILEPSY IN CHILDREN WITH FEBRILE SEIZURES

Abstract

This study was conducted to evaluate the risk factors of recurrence and development of epilepsy in children with febrile seizures at Pediatrics Department of Ibn-e Sina Hospital, Multan from January 2023 to January  2025.A total of 100 children with febrile seizures being follow-up for at least 1 year were included in the study. All patients whose guardians reported more two occurrences of febrile seizures, complex febrile seizures and an episode of febrile seizure with neurodevelopmental delay underwent electroencephalogram. Children with ≥2 unprovoked seizures after febrile seizure occurrence and those with an unprovoked seizure showing epileptiform discharges as detected on an EEG were suspected for development of epilepsy. Results showed that FS recurrence was significantly associated with type of seizure(p<0.001) and family history of epilepsy (p=0.030). Logistic regression analysis revealed that patients who suffered from a seizure after one hour of developing a fever had a 7 times greater chance of recurrence and those with longer episodes had 3 times more risk. Patients who had a FS onset at younger than 1 year were 18 folds more likely to develop epilepsy and 10 folds in those with longer seizure duration. In conclusion, younger than 1-year, complex seizures, seizures within 1 hour of fever, low fever before FS onset and family history are significant risk factors of FS recurrence in children with febrile seizures. Development of epilepsy in such patients is significantly associated with FS onset at younger than 12 months of age, longer seizure duration, clonic seizures, neurodevelopmental delay, abnormal EEG, recurrent FS and complex FS.
