EP refers to Epilepsy, which is the abbreviation of English epilepsy, commonly known as "epilepsy" or "epilepsy". EP is a chronic disease caused by sudden abnormal discharge of brain neurons, which leads to temporary brain dysfunction. According to the latest epidemiological data in China, the overall prevalence rate of epilepsy in China is 7.0‰, the annual incidence rate is 28.8/65438+ 10,000, and the prevalence rate of active epilepsy in 1 year is 4.6‰.

Based on this, it is estimated that there are about 9 million people with epilepsy in China, of which 5-6 million are active epilepsy patients, and there are about 400,000 new epilepsy patients every year. In China, epilepsy has become the second most common disease in neurology after headache.

clinical picture

Epilepsy occurs in all ages. The incidence of epilepsy in children is higher than that in adults, and it decreases with age. Entering the old age (after 65 years old), the incidence of epilepsy has increased due to the increase of cerebrovascular diseases, Alzheimer's disease and neurodegenerative diseases. The clinical manifestations of epileptic seizures are complex and varied because of the different starting sites and conduction modes of abnormal discharges.

Typical absences are sudden occurrence, pause, gaze, no response to call and blinking, but there are basically no or slight motor symptoms, and the end is sudden. It usually lasts for 5-20 seconds, and rarely exceeds 1 minute. Mainly seen in children's absence epilepsy.
