If neurological convulsions occur after brain tumor surgery, epilepsy is most often considered to be associated with the surgery, and hypocalcemia is not excluded. If the electrolytes are normal and the convulsions are still present, it is most likely due to epilepsy after surgery. For patients who develop epilepsy after brain tumor surgery, medication is needed to bring the symptoms of epilepsy under control, because once epilepsy occurs, it can lead to lack of oxygen in brain tissue and aggravate the symptoms of neurological damage in patients, so controlling epilepsy is the first step. After the use of drugs, in the follow-up process, it is necessary to insist on taking antiepileptic drugs until the epilepsy is completely controlled and can be considered to gradually stop the drugs.
