Other alternatives to treat epilepsy include medications, diets, and surgery. Medications used to treat epilepsy can range from anticonvulsants, such as phenytoin or valproic acid, to newer drugs like levetiracetam or lacosamide. Diets like the ketogenic diet have been shown in some studies to reduce seizures. The diet is a high-fat, low-carbohydrate plan that can help manage seizure activity when medication isn’t enough. Surgery may also be an option for those who don’t respond well to drug therapy. A procedure called hemispherectomy has been successful in reducing seizures in severe cases of epilepsy that are unresponsive to other treatments.
