The Atlas of Headache Disorders presents the findings of the first global enquiry into headache disorders and health-care resource allocation to headache, providing the most comprehensive compilation of information on these matters, gathered from 101 countries. The facts and figures presented within it illuminate the worldwide neglect of a major cause of public ill-health and reveal the inadequacies of responses to it in countries throughout the world.

This report is the result of a collaborative effort between the World Health Organization and Lifting The Burden: The Global Campaign Against Headache.
