Epilepsy is a transient episodic brain dysfunction caused by abnormal discharges of nerve cells in the brain.Can Glioma Trigger Epilepsy After Surgery? There are two main types of tumor triggering epilepsy. First, due to the growth and location of the glioma, it presses on the functional areas of the brain, resulting in abnormal discharges of neurons in the brain, which manifests the symptoms of epilepsy. This kind of epileptic symptoms will appear before the surgery, but through the surgery, most patients’ epileptic symptoms will disappear, but some patients still have seizures after the surgery and need to continue to take anti-epileptic drugs. Second, epilepsy symptoms appear after surgery. Seizure symptoms may appear within one week after surgery or several months after surgery, the former may be caused by edema and bleeding of local lesions after surgical resection of tumor, the latter is because of the formation of scar in the brain area where the tumor is resected, which will lead to the appearance of epilepsy with the proliferation of the scar, and the appearance of both situations requires the use of antiepileptic drugs according to the doctor’s instructions or the consideration of surgical treatment. In the treatment of gliomas that lead to secondary epilepsy is not to be ignored, the best way to prevent epilepsy in advance, whether or not there is no epilepsy before the operation, after the operation to take anti-epileptic drugs. If there is no epilepsy before surgery and no epilepsy occurs in the short term after surgery, then the medication can be tapered off for 2 weeks after surgery until it is stopped. Patients with epilepsy symptoms before surgery should take anti-epileptic drugs for at least 3 months after surgery, and review the EEG after 3 months, if there are no epileptic waves on the EEG, then the drugs can be gradually reduced according to the doctor’s prescription until they are stopped; if the EEG is not normal or there is a recurrence of epilepsy after a period of time, then it is necessary to continue to take anti-epileptic drugs according to the doctor’s prescription for more than half a year without any recurrence of seizures, and then diagnose according to the condition after the review of the EEG to determine whether or not to The drug should be reduced or discontinued according to the situation. Antiepileptic drugs need to be gradually reduced over a period of several weeks until they are stopped according to medical advice, and they cannot be stopped immediately to prevent seizures from recurring. Some patients feel that there are no more seizures, so they just stop taking the medication. This will easily make the seizures come back, and then they have to start taking the anti-epileptic medication again at the original dosage, which will make the whole anti-epileptic process even more arduous and complicated.
