Good news for most migraine sufferers: With age, you can expect to get fewer, less- painful migraine attacks that don’t last as long, a new study from Sweden suggests.

“It does seem that in most people migraine is not a progressive disease,” says Carl Dahlof, MD, PhD, a neurologist and medical director and founder of the Gothenburg Migraine Clinic in Gothenberg. He presented his findings this week at the American Headache Society annual meeting in Chicago. But you may have to be patient. “The average duration is 25 years,” Dahlof tells WebMD. “The average age of onset is about age 20.”
