A seizure is a finite event of altered cerebral function because of excessive and abnormal electrical discharges of the brain cells. Epilepsy is a chronic condition predisposing a person to recurrent seizures. Epilepsy is common, affecting approximately 2 million people in the United States at any one time with a world-wide age-adjusted incidence of 16–111/100,000 people per year. It has been estimated that about 7%–8% of the population experiences at least one epileptic seizure during their lifetimes . The basic mechanism of epileptic seizures has not been fully elucidated. The classification of epileptic seizures by the International League Against Epilepsy was last revised in 2010.
