Epilepsy is a chronic brain disorder caused by multiple causes, characterized by recurrent seizures due to excessive neuronal discharge in the brain; single or occasional epileptic seizures and those that occur during acute illness are not included in epilepsy. It is emphasized that epilepsy is a “chronic brain disorder” with “abnormal discharges” and “recurrent seizures” in nature. The first thing you need to do is to have a prenatal diagnosis of epilepsy caused by hereditary diseases, and to abort the fetus with epilepsy to reduce the occurrence of such epilepsy. The fiancé (wife) of an epileptic patient should have an EEG topographic examination before marriage, if there are epileptic waves on the EEG topographic map to avoid marriage, and people with a family history of epilepsy on both sides should also avoid marriage. In order to prevent epilepsy caused by brain injury at birth, for elderly first-time mothers, 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 these infections from occurring. 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, 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 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.
