"Migraine headaches are a major public health problem affecting more than 28 million persons in this country.1 Nearly 25 percent of women and 9 percent of men experience disabling migraines.2,3 The impact of these headaches on patients and their families is tremendous, with many patients reporting frequent and significant disability.4 The economic burden of migraine headaches in the United States is also tremendous. Persons with migraines lose an average of four to six work days each year, with an annual total loss nationwide of 64 to 150 million work days. The estimated direct and indirect costs of migraine approach $17 billion.5,6 Despite the prevalence of migraines and the availability of multiple treatment options, this condition is often undiagnosed and untreated.7 About one half of patients stop seeking medical care for their migraines, in part because of dissatisfaction with the therapy they have received.4"
