Worldwide, migraines strike roughly 12% of people at least once per year, with women roughly three times as likely as men to have an attack. The Migraine Research Foundation estimates that U.S. employees take 113 million sick days per year because of migraines, creating an annual loss of $13 billion. The toll underscores how little current treatments—not just drugs, but nerve-numbing injections, behavioral therapies, and special diets—can help many people. On the horizon, however, is a new class of drugs that many scientists believe can stop migraines at their root.
