Epilepsy is one of the most common chronic diseases of the nervous system in children, and it is a disease with a high disability rate and a long course, which seriously threatens the physical and mental health of patients (especially children and adolescents). According to statistics, the prevalence of epilepsy in China is 0.7%, according to which it is estimated that there are about 9-10 million epilepsy patients in China, while the number of new patients increases about 400,000 every year, the majority of whom are children and adolescents. Epilepsy is a chronic, recurrent (sudden onset, sudden termination) disease caused by abnormal nerve cell discharges in the brain, with a variety of clinical symptoms, but the same patient has the same seizure each time. The causes of epilepsy are many and complex. In general, epilepsy can be divided into two main categories from etiology. The first is primary epilepsy: this type of epilepsy accounts for 20% of the total number of epilepsy patients and has no known cause. The second is secondary epilepsy or symptomatic epilepsy: congenital malformations of brain development, neurocutaneous syndromes, genetic metabolic diseases, perinatal brain injury, intracranial infections, nutritional metabolic disorders and endocrine diseases, cerebrovascular disease, traumatic brain injury, complex post-febrile convulsion brain injury, brain tumors, brain degenerative diseases, toxic encephalopathy. Once epilepsy is diagnosed, active medical treatment should be sought.
