Anne Stein's excellent article on epilepsy surgery ("Most epilepsy surgery candidates don't opt for it," Feb. 16) omits several crucial facts. Candidates for epilepsy surgery not only must have seizures refractory to two appropriately used medications but must have the seizures originating from one location. That location must be in a brain area accessible to the surgeon and not vital to the patient. When these criteria are not met, or when patients or the families of young patients do not agree to surgery, the ketogenic diet, a medically supervised high-fat, low-carbohydrate, adequate protein diet, may be as effective in controlling or even curing seizures as the figures given for the successes of surgery.
