Prevalence of Migraine Headache in Canada: A Population-Based Survey

Abstract

We estimate that 2.6 million adult females and 0.8 million adult males in Canada are migraineurs, but only half are likely to have been diagnosed by a physician. Contrary to a recent US survey, people from lower income households in Canada are not at greater risk of migraine. The lower prevalence of migraine in Quebec was unexpected and remains unexplained, but it may be influenced by language/translation problems.
