Meningitis patients with convulsions may be caused by high cranial pressure, which is treated mainly with cranial pressure-lowering drugs, such as mannitol, glycerol fructose and tachyphylaxis. If the patient has a single seizure, anti-seizure medication is not required. If the patient has more than two seizures, anti-seizure medication is usually routinely applied, and commonly used drugs include sodium valproate and carbamazepine. If the patient has hyponatremia, convulsions can also occur in severe cases, and the main treatment is sodium replacement, which can be done by intravenous pumping of concentrated salt or oral sodium chloride. If the patient has meningococcal infection, it may cause the patient to have fever, and in severe cases, the patient may also have convulsions.
