Currently, the implantation of electrodes in epilepsy is only for the purpose of precise localization and to assist further treatment, but not a measure that plays a real therapeutic role. Epilepsy is a common disease in neurology, which is a neurological disorder caused by synchronized abnormal discharges of multiple brain nerves. In general, epilepsy can be well controlled with medication alone, and some benign epilepsies only develop in children, and by the time they reach puberty or adulthood, there is a high probability that they will resolve themselves and stop having seizures, while refractory epilepsies are not so simple. Refractory epilepsy is characterized by more frequent and prolonged seizures, poorly controlled by medication, and requires surgical resection. It is difficult to precisely locate the epileptic lesion by external EEG measurements, and if the resection area is large, it can lead to huge sequelae or even be life-threatening. The implantation of electrodes is designed to minimize the risk of surgery and control seizures. When epilepsy occurs, it is necessary to actively consult the doctor and follow the doctor’s instructions for reasonable treatment.
