The prevalence, impact, and treatment of migraine and severe headaches in the United States: a review of statistics from national surveillance studies.

Abstract

Four ongoing U.S. public health surveillance studies gather information relevant to the prevalence, impact, and treatment of headache and migraine: the National Health Interview Survey, the National Health and Nutrition Examination Survey, the National Ambulatory Care Survey, and the National Hospital Ambulatory Medical Care Survey. The American Migraine Prevalence and Prevention (AMPP) study is a privately funded study that provides comparative U.S. population-based estimates of the prevalence and burden of migraine and chronic migraine.
