According to the proposal of the World Health Organization (who) and the international anti epileptic Association, epilepsy is currently considered to be a chronic brain dysfunction syndrome caused by a variety of causes, which is caused by repeated supersynchronous discharges of brain nerve cell groups. During the attack, there was a sudden and transient brain dysfunction, accompanied by various types of clinical attacks. During the interval, the patient was normal. The clinical manifestations of epilepsy can be varied. In addition to conscious changes and motor convulsions, there can also be sensory abnormalities, mental disorders and behavioral abnormalities. The expression of these abnormalities and the intensity of seizures mainly depend on the brain area of abnormal discharge.
