Epilepsy is a clinical syndrome characterized by recurrent abnormal electrical discharges in the brain, leading to temporary disruption of brain function. Patients may experience seizures, which manifest as various degrees of dysfunction in motor, sensory, cognitive, autonomic, and psychiatric functions. Commonly used antiepileptic drugs include sodium phenytoin, carbamazepine, phenobarbital, ethosuximide, and clonazepam.
