All epileptic patient will be recruited from outpatient epilepsy clinic, Department of Neurology, Mansoura University hospital. The control consists of 60 Age and gender matched healthy individual with negative past and family history of epilepsy and febrile convulsion.\n\nSubjects:\n\nInclusion criteria:\n\n1. Patient with diagnosis of epilepsy (idiopathic or cryptogenic/symptomatic), according to the International League Against Epilepsy classification confirmed by electroencephalogram.\n2. Treatment with at least one AED, long enough to achieve the optimal dose; drug-resistance and drug-responsiveness, according to the criteria ILAE 2010.\n3. Written consent obtained from a patient or legal guardian.\n\nExclusion criteria:\n\n1. Patient with severe adverse anti epileptic drug reactions.\n2. Patient with unreliable records of seizure frequency.\n3. Patient with poor compliance with AEDs,.\n4. Patient with significant psychiatric comor- bidity,\n5. Patient with progressive systemic disorders .\n6. Patient with history of alcohol or drug abuse.\n7. Epileptic patients in clinical remission or with gradual withdrawal of therapy.\n8. Epileptic patients with therapy titration phase.\n\nMethods:\n\nAfter an informed consent, all participants will be subjected to the following;\n\n1. A detailed history taking; including age, sex, age of onset , type of seizure, duration of epilepsy, pretreatment and post treatment seizure frequency , and drugs (antiepileptic drugs, others).\n2. Full laboratory investigation including (complete blood count, liver function test, serum creatinine, electrolyte assay, thyroid profile, blood sugar test).\n3. Serum level of antiepileptic drug.\n4. Electroencephalogram in order to localize site of paroxysmal activity.\n5. MRI brain: T1, T2 and FLAIR: axial and coronal cuts to detect any structural abnormalities,\n6.
