Not all epilepsies are suitable for surgical treatment. Internationally, most epilepsies are still primarily treated with pharmacological control, less than 40% of patients can be considered for surgical treatment after a detailed pre-surgical evaluation, and only 50-60% of patients who undergo surgery reach a lifelong cure. What types of patients can be considered for surgery? First, the patient has focal epilepsy rather than generalized epilepsy, i.e., not simultaneous discharges throughout the head. If the lesion causes secondary epilepsy, removal of this epileptic focus can cure the epilepsy. Second, intractable epilepsy that is difficult to control with drugs, and the seizures cannot be controlled with 1-2 or 3 antiepileptic drugs. That is, the control by medication is not satisfactory and has a great impact on daily work. Surgical treatment can be considered. Third, seizures are disabling, affecting memory, thinking and quality of life (work, life, study and social life, etc.) after seizures, surgery can be considered. IV. Regular medication for 2 years before surgery (but lesions in the brain, or early diagnosis of medial temporal lobe type epilepsy should be operated as early as possible). V. For infants or children, especially catastrophic epilepsy, which affects brain development and cognitive ability, surgery should be performed as early as possible, the sooner the better. Sixth, surgical treatment does not cause serious functional impairment. That is, there will be no hemiplegia or speech impairment after surgery, and the surgery is not life-threatening. Seven, the patient’s family can objectively understand the expected results of the surgery and agree to the surgery. It must be recognized that only half of the patients can be cured for life, and the other half of the patients can have their seizures reduced and still need to take long-term medication after surgery.
