Most epilepsy can be prevented as long as active preventive measures are taken. 1. Genetic predisposition is the occurrence of convulsive susceptibility in certain children, which produces seizures prompted by various environmental factors. In this regard, special emphasis should be placed on the importance of genetic counseling. A detailed systematic family survey should be conducted to find out whether there are seizures and their characteristics in both parents, siblings and close relatives of the patient, whether there is a history of febrile convulsions, and a rough estimate of the possible incidence in their siblings, offspring and other relatives. 2. When choosing a marriage partner for a person with epilepsy, people with a family history of epilepsy on both sides should avoid getting married. Also pay attention to the issue of marriage and childbirth to avoid the occurrence of children with epilepsy and to improve the quality of the population. For certain serious genetic diseases that cause mental retardation and epilepsy, prenatal diagnosis, or neonatal over-screening should be performed to decide to terminate the pregnancy or to treat it early. For epilepsy caused by hereditary diseases, prenatal diagnosis should be performed, and fetuses found to have certain hereditary diseases with epilepsy can be aborted so that the occurrence of such epilepsy can be reduced. In order to prevent epilepsy caused by brain injury at birth, for senior primiparas, if the birth process is expected to be uneventful, the fetus should be removed by caesarean section early, so as to avoid epilepsy in the baby later due to hypoxia, asphyxia and birth injury. For epilepsy caused by various intracranial infections, the main thing is to actively prevent the occurrence of these infections, and once intracranial infectious diseases occur, early diagnosis and proper treatment should be made to reduce the degree of brain tissue damage. In the acute phase of intracranial infection, many patients often have seizures, which should be promptly and in sufficient quantity with antiepileptic drugs to reduce the damage to brain tissue caused by seizures, and also reduce the chance of seizures in the future. 5, prevention of epilepsy caused by traumatic brain injury, focusing on the prevention of traumatic brain injury, avoid traumatic brain injury caused by work, traffic accidents. 6, patients with febrile convulsions later about, a few will turn into epilepsy, such as the possibility of recurrence of febrile convulsions, should take early preventive measures, can greatly reduce the brain damage caused by febrile convulsions, but also reduce the incidence of epilepsy. 7. Removing seizure triggers is one of the important aspects to prevent recurrence of epilepsy, such as alcohol consumption, fatigue, mental depression, overeating, infectious diseases, frightening fever, sleep deprivation, marriage of close relatives and harmful sound and light stimulation.
