Unlike the first generation antiepileptic medications, newer drugs for epilepsy such as levetiracetam are reported to have less adverse effect in children but not many studies have systematically reviewed the subject. This study aims to prospectively evaluate the effect of levetiracetam on neurocognition, behavioral issues and quality of life, as well as its seizure control efficacy and other adverse events in pediatric epilepsy patients, in comparison to carbamazepine, one of the classic antiepileptic medication, widely prescribed for both partial and generalized seizures, despite its well known side effects.
This multicenter, open-label, parallel-group trial is expected to enroll 130 patients from age 4 to 16 woh will be randomized into two groups, which will be prescribed with levetiracetam or carbamazepine. Series of neuropsychological assessment and behavioral and life evaluations of the patients will be performed at baseline period and after the 52 weeks of study period.

Levetiracetam is a second-generation antiepileptic drug that has been approved for the treatment of epilepsy in both children and adults. This anticonvulsant works by binding to the synaptic vesicle protein 2A resulting in a possible effect on neurotransmitter release from presynaptic vesicles, while the exact mechanism of action is still unclear. In both adults and children, levetiracetam treatment in has a proven efficacy in both localization-related and generalized epilepsies. In contrast to first generation, levetiracetam reports less side effects of somnolence or lethargy, but behavioral adverse events, such as changed mood state, aggression, and irritability are noted, but only a few studies have reported such effects in a systemic fashion.
|Active Comparator: Carabamazepine||
Carbamazepine, a first-generation antiepileptic medication, stabilizes the inactivated state of voltage-gated sodium channels, making fewer of these channels available to subsequently open, which leaves the affected cells less excitable and less seizure prone. It is approved for both focal seizures and generalized tonic-clonic or combined seizures for adults and children.
- Assessment and comparative analysis of initial and follow-up Neuropsychological evaluation in both treated groups. (Levetiracetam and Carbamazepine) [ Time Frame: 52 weeks ]changes in a series of follow-up neurocognitive, behavioral, and emotional function tests (Korean Wechsler Intelligence Scale for Children-Third edition (K-WISC-III, for subjects 6-16 years old)19, 20 or the Korean Weschler Preschool and Primary Scale of Intelligence-Third edition (K-WIPSSI-III, for ages 4-6), Korean-Child Behavior Checklist (K-CBCL), Children's Depression Inventory (CDI) 24 and Revised Children's Manifest Anxiety Scale (RCMAS))
- Seizure control efficacy [ Time Frame: 52 weeks ]Comparison of baseline frequency to final follow-up frequency during the last 24 weeks of the maintenance period(at last visit at 52 week time point)
