Epilepsy is a group of common diseases, which is a chronic brain disease with sudden abnormal discharge of neurons in the brain leading to transient brain dysfunction. In recent years, the incidence of epilepsy has been increasing year by year. If seizures are not properly controlled, they can bring many hazards to patients, their families and society. The first is the psycho-psychiatric aspect. Epilepsy is a long, recurrent disease with unpredictable seizures. Therefore, patients not only endure unimaginable pain during each seizure, but also worry about the possibility of seizures at all times, especially for patients and their families who are clear-headed, and the misunderstanding and discrimination against epilepsy in society, which greatly affects the psychological and mental aspects of patients. Second, seizures can easily lead to trauma. Patients may be injured by sudden loss of consciousness, touching hard objects, sharp objects, flames, boiling water, chemicals, etc. during seizures. Accidental bruises may not be apparent to children of small stature, but are especially apparent to adolescents and adults who have the ability to move on their own. Third, seizures can lead to life-threatening injuries. The main ones are persistent status epilepticus, accidents, suicide, and sudden death that cannot be explained. Persistent status epilepticus with generalized seizures is often accompanied by varying degrees of consciousness, motor dysfunction, and in severe cases, cerebral edema and increased cranial pressure. Even with aggressive resuscitation, the death rate is still 3.6%. The average life expectancy of children and young people with frequent seizures is significantly lower than that of the general population, and according to the International League Against Epilepsy, the mortality rate of young people with epilepsy is four times higher than that of normal young people. Among them, 10% die directly from epilepsy or status epilepticus, 5% die from accidents during seizures (such as drowning, falling from height, head trauma, burns, etc.), 7%-20% die from suicide, and the rest belong to sudden death that cannot be explained by epilepsy itself, i.e. sudden epileptic death. Therefore, it is very important to control seizures as much as possible so that patients and their families can get a normal life order, regardless of whether medication or surgical treatment is taken. The Chinese Anti-Epilepsy Association has done a survey, and the majority of families can accept a certain degree of disability for the patient, but cannot tolerate the endless suffering caused by frequent seizures that prevent the whole family from living in peace.
