The goal of this interventional study is to learn about the efficacy and safety of first line anti epileptic drugs (AEDs) as substitution therapy for children who are resistant to second-line AEDs. The main question to answer it aims are : how much the difference proportion of responders (responders are children who achieve the decrease of seizure frequencies by 50%) how much time it is needed to achieve the decrease of seizure frequencies by 50% The patients who are eligible for the study and have given their consent, will be enrolled, divided into 2 groups, the control and intervention. The participant should follow the 14 weeks of intervention that consists of 6 phases : baseline, initial dose, titration dose, maintenance dose, tapering-off dose, and new combination maintenance dose.
Each phase of the study is described below In baseline phase, data such as demographic, clinical characteristic including seizure frequency, seizure type, seizure onset, medication history, family history of seizure, and also developmental stages, will be recorded from electronic medical record. Besides, the CT-scan or MRI are also collected from the same source. After that, their quality of life will be assessed by QOLCE-55 validated questionnaire through self-guided report. Furthermore, the laboratory investigation and EEG will be performed. The next phase is intervention phase, started from initial phase and ended by the maintenance of new combination therapy phase, takes with overall 12 weeks. Initially, the substitution drugs with each initial dose are consumed. The drugs consist of valproic acid for the generalized and carbamazepine for focal epilepsies. On the other hand, the control group will take lamotrigine or clobazam for generalized and oxcarbazepine for focal ones. The phase continuous to titration dose, in which, the dose is raised gradually until it causes 50% of seizure reduction, and the next step is maintained the dose for about 2 weeks. \- The following is tapering-off and after that stopping the substituted drug, levetiracetam or topiramate, which is determined by considering individual condition. Yet, if the seizures increase more than one and a half time of the previous frequency during the phases, the intervention will be ended immediately. On the contrary, if the condition is better, then the children go to the maintenance of new combination, that is the substitution drug and the old drugs in which the seizures do not go up or even better keep going down.

RECRUITINGthe different proportion of responders between groups who get first-line anti-epileptic drugs (intervention) and second-line anti-epileptic drugs (control)
responders are children who get the reduction of seizure frequency by 50%
Time frame: trough the study completion, about 14 weeks
time to achieve the reduction of seizure frequency by 50% or more among responders
time that is counted in week and is divided into 3 categories , 2-\<4 weeks, 4-\<8 weeks and 8-12 weeks
Time frame: during intervention, about 12 weeks
the difference of quality of life between groups who get first-line anti-epileptic drugs (intervention) and second-line anti-epileptic drugs (control)
quality of life is assessed by validated instrument QOLCE-55. It has 55 questions including cognitive (22 items), emotional (17 items), social (7 items) and also physical (9 items) function. Items are rated on a five-point Likert scale, 0 = very often, 1 = fairly often, 2 = sometime, 3 = almost never, 5 = never. The composite score is the unweighted average of the four subscales, ranging from 1-100, higher score indicates better quality of life. b. Differences in quality of life: quality of life assessment using QOLCE-55 instrument. The average of each function (cognitive, emotional, social and physical functions) and the average of the total functions are assessed. This variable is categorized into: * Different, if there is a difference in the average quality of life * Not different, if there is no difference in the average quality of life
Time frame: at baseline phase in the 1st week (before intervention) and after intervention in the 14th week
the difference of the electroencephalography (EEG) changing between groups who get first-line anti-epileptic drugs (intervention) and second-line anti-epileptic drugs (control)
The EEG examination is operated two times, at the baseline and post intervention phase, with high density machine (Caldwell Easy III) is done twice, pre- and post-intervention. The machine will operate for about 45 minutes including 5 minutes each for eye-open and eye-close in every subjects. Beginning with acquisition, EEG recordings use standard parameter to analyze brain activity at various frequencies to gain good quality and artefact-free result. The printed results of the EEG is available for about 4-7 days after the examination. EEG recording results are categorized into: * Normal : does not show of hypofunction/asymmetry/epileptiform waves * Abnormal: shows a picture of hypofunction/asymmetry/epileptiform waves or a combination of 1 or more of these features The subjects who show changes in their EEG are later grouped into groups of abnormal to normal or abnormalities that showed improvement. Abnormalities that show improvement, for example are hypofunction (slowing down)
