In ancient Rome, patients with unbearable head pain were sometimes treated with jolts from the electricity-producing black torpedo fish, or electric ray. Scribonius Largus, physician to Emperor Claudius, was a staunch advocate of the remedy. “To immediately remove and permanently cure a headache, however long-lasting and intolerable, a live black torpedo is put on the place which is in pain, until the pain ceases and the part grows numb,” he wrote in the first century. Electric fish have long disappeared from the medical armamentarium. And patients with headaches are most frequently treated with pharmaceuticals. But recently, electrical or electromagnetic devices that hark back to the head-zapping torpedo fish have come into vogue among the country’s most prominent migraine researchers. Two different kinds of stimulatory devices are now in large-scale clinical trials for possible use in patients with the most severe migraine cases. Many researchers believe that such devices are likely to play a greater role in migraine treatment in the future. Roughly 30 million Americans suffer from migraines, an inherited neurological disorder characterized in part by painful, throbbing headaches.
