Abstract

The intractable partial epilepsy outcome information is important in determining not only when epilepsy surgery evaluation should begin but also in deciding who would benefit and what is the likelihood of any benefit from surgery. Medical records of 50 children diagnosed with nontumor-related partial seizures, confirmed by video-electroencephalography (video-EEG), had at least one seizure per week and were followed for at least 2 consecutive years after video-EEGs were reviewed. There were 30 patients who continued with antiepileptic drug treatment after video-EEG. The seizure outcome analysis revealed a significant improvement of seizure control in the first year of follow-up but no difference between the first year and the following 3 years. Only 30% had excellent long-term outcome (seizure free or less than one seizure per 6 months). The presence of focal lesions on neuroimaging was the only risk factor of poor outcome. The other 20 patients underwent epilepsy surgery after video-EEG; 60% attained excellent outcome despite the fact that 90% had focal neuroimaging abnormality. Children whose partial epilepsy remained intractable after 1 year of antiepileptic drug treatment should be evaluated for candidacy of epilepsy surgery, particularly those who have focal lesions on neuroimaging.
