Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Various biomarkers of brain damage have been studied in the context of epilepsy and brain damage but most widely investigated biochemical biomarker is neuron-specific enolase (NSE). NSE is γγ-isoenzyme of enolase involved in glycolysis pathway. NSE originates predominantly from the cytoplasm of neurons and neuroendocrine cells. Neuronal damage and impairment of blood brain barrier integrity can be detected by the release of NSE into cerebrospinal fluid (CSF) and eventually into blood. NSE is therefore regarded as a marker of neuronal damage and prognosis in various disorders associated with cell damage in the central or peripheral nervous system.
CSF and serum NSE levels obtained within first 48 hours were found to be elevated and correlated well with the duration of epilepsy and outcome of patients. Some studies have shown elevated NSE levels in temporal lobe epilepsy, after single tonic-clonic seizures, and status epilepticus. Literature review reveals that there is lack of data on serum NSE in focal seizures and there is no study on the effect of antiepileptic drugs on the level of serum NSE. So the present study has been planned to assess the level of serum NSE in focal seizures and its changes after antiepileptic therapy.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Healthy control
Twenty five (25) healthy individuals of same age group will serve as the control group. Control subjects will be evaluated at baseline only.
No interventions assigned to this group
Carbamazepine group
Twenty five (25) patients recruited in this group will receive Tab. Carbamazepine. Carbamazepine will be started with a dose of 200 mg/day for one week and then increased to 400 mg/day for one week and then 600mg/day for next two weeks.
Carbamazepine
Carbamazepine will be started with a dose of 200 mg/day for one week and then increased to 400 mg/day for one week and then 600mg/day for next two weeks.
Oxcarbazepine group
Twenty five (25) patients recruited in this group will receive Tab. Oxcarbazepine. Oxcarbazepine will be started with 10mg/kg daily dose for one week followed by 15mg/kg daily for next one week and then will be increased to 20mg/kg for next two weeks.
Oxcarbazepine
Oxcarbazepine will be started with 10mg/kg daily dose for one week followed by 15mg/kg daily for next one week and then will be increased to 20mg/kg for next two weeks.
