Although epilepsy is characterized by sudden and recurrent seizures, most epilepsies can be prevented by taking active preventive measures. 1. For epilepsy caused by hereditary diseases, prenatal diagnosis should be performed, and fetuses found to be suffering from certain hereditary diseases with epilepsy can be aborted so that the occurrence of such epilepsy can be reduced. The fiancé (wife) of an epileptic patient should have an EEG topographic examination before marriage, and those with epileptic waves on the EEG topographic map should avoid getting married, and those with a family history of epilepsy on both sides should also avoid getting married. In order to prevent epilepsy caused by brain injury at birth, for elderly primigravida, if the birth process is expected to be uneventful, early caesarean section should be performed, so that the baby can avoid epilepsy caused by hypoxia, asphyxia and birth injury later on. For epilepsy caused by various intracranial infections, it is important to actively prevent the occurrence of these infections. Once intracranial infectious diseases have occurred, they should be diagnosed early and treated correctly to reduce the degree of brain tissue damage. In the acute phase of intracranial infection, many patients often have seizures, when antiepileptic drugs should be used in a timely and adequate amount to reduce the damage to brain tissue caused by seizures and also to 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, to avoid traumatic brain injury caused by work, traffic accidents. 6, about 15% of patients with febrile convulsions later turn into epilepsy, if there is a possibility of recurrence of febrile convulsions, preventive measures should be taken early, which can greatly reduce the brain damage caused by febrile convulsions, and also reduce the incidence of epilepsy. 7. Removing seizure triggers is one of the important aspects of preventing seizure recurrence, such as alcohol consumption, smoking, fatigue, mental depression, overeating, infectious diseases, fever with shock, sleep deprivation, marriage of close relatives and harmful sound and light stimulation. 8, the most important point of drug treatment is that once you start taking medication, you must insist on taking it, never interrupt, only then can you effectively control the seizure, if the seizure has been completely controlled, reduce the amount of medication should be gradually reduced, not suddenly stop. If a relapse occurs during the discontinuation or reduction of medication, the original treatment dose should be restored immediately under the guidance of a doctor.
