The epidemiology of migraine.

This article provides a review of the epidemiology and risk factors for migraine in population studies, as well as patterns for healthcare use. The burden and costs of migraine, as well as risk factors for disease progression, are also discussed. Although migraine is a remarkably common cause of temporary disability, many persons with migraine, even those with disabling headache, have never consulted a physician for the problem. Prevalence is highest in women, in persons between the ages of 25 and 55 years, and, at least in the United States, in individuals from lower income households. However, prevalence is high in groups other than these high-risk groups. In a subgroup of patients, migraine may be a progressive disorder.
