Initial dose was 2 mg/kg/day, increased after 2\~4 weeks to 6\~8 mg/kg/day.
Percentage of Participants Who Were Assessed As Seizure Free
63.1 percentage of participants
57.6 percentage of participants

SECONDARY outcome

Timeframe: Baseline and 24 weeks

Cognitive assessment was performed using K-WISC-III. The total score of K-WISC-III is calculated as Full Scale IQ which ranges from 31 (worst) to 151(best). Higher scores indicate greater intelligence, lower scores indicate less intelligence. Thus a positive change indicated an improvement.

SECONDARY outcome

Timeframe: Baseline and 24 weeks

The difference of K-CBCL between before and after the administration. K-CBCL is the Korean version of CBCL which is a standardized form that parents fill out to describe their children's behavioral and emotional problems. The total score ranges 0- 234, with higher scores indicating worse behavioral and emotional problems.
