Epilepsy is commonly known as “sheep epilepsy”, and its seizures are like walking in a fierce war zone full of landmines, which can lead to “explosion-like” seizures if touched accidentally. The number of people with epilepsy in China is about 9 million, of which about 20-30% are patients for whom the combination of multiple drugs is ineffective, which means that nearly 2 million people are living in a mine-ridden war zone every day and are at risk of losing their lives at any time. Epilepsy is a transient abnormal discharge of neurons in the brain, hidden in the most sophisticated and complex brain with 10 billion nerve cells, to prepare for locating the epileptogenic focus and to preserve the functional area intact, i.e. to remove the discharge site and not to affect the function of the limbs, which simply discourages many families. There are many different forms of seizures and many different parts of the body involved in epilepsy, so it is not easy to find the minefield more accurately and to completely remove this deadly “landmine”. Epilepsy surgery is different from the common brain tumors. In addition to understanding the disease, it is necessary to master the electrophysiology and neuropsychology to preserve the functional areas to the greatest extent possible, and to obtain the maximum therapeutic effect with the minimum extent of resection. Seizures are characterized by a series of transient abnormal discharges of neurons in the brain invisible to the naked eye. Such abnormal discharges are described only by EEG, and scalp EEG is often not clearly captured due to the cutting effect, and some patients need to insert pterygoid electrodes for EEG to be judged. In addition to EEG plus clinical symptoms, a combination of MRI and PECT as well as neuropsychological assessment is needed. These are often not enough, and for complex patients, electrodes need to be implanted in the brain first for repeated EEG monitoring and localization, and some patients need to be given electrical stimulation evoked potentials during surgery, and epilepsy surgery is the result of this continuous exploration.
