Abstract

Background: Febrile seizures are the most common convulsion disorder in childhood. The possible risk of developing epilepsy in febrile seizures is about 2-10%. EEG is helpful to diagnose epilepsy; however, there are controversies about the abnormal EEG and associated risk factors .The aim of this study was to determine EEG abnormality and effective risk factors in patients with complex febrile seizures.

Methods: This study was conducted on the patients with complex febrile seizures in 2009-2010.EEG   was performed on all children 6 to 10 days after seizure and reported by a neurologist. Demographic data and risk factors, including age, sex, family history of epilepsy and febrile convulsions, presentation of seizure, postictal neurological disorder were documented by a checklist and their association with EEG was analyzed.

Results: 111 patients with complex febrile seizure, 70 girls and 41 boys, with the mean age of 3.4±20 months were studied. EEG was abnormal in 37.8% of patients, 9% were epileptic form abnormality and 28.8% were nonspecific abnormal.

There was a statistically significant association between EEG abnormality in patients with focal seizures, family history of febrile seizures and postictal neurologic disorder (p<0.05).

Conclusion: The results of this study showed abnormality of EEG in complex febrile convulsions in 37.8% of patients, which was significantly higher in patients with postictal neurological disorder, focal seizures and family history of febrile seizure.
