Table 1. NIH Funding and Disease Burden for Migraine, Headache Disorders and Other Chronic Disorders.

NIH has reported fiscal year 2007 funding for all disorders listed in table except migraine and headache disorders ¹⁰. NIH research funding for headache disorders in FY2007 is an estimate of the mean annual migraine funding across FY2003 to FY2006 which has been previously published ². Annual US economic costs attributable to all headache disorders were derived by adding the indirect costs of all headache disorders ($20 billion) ⁴ to the direct costs for migraine excluding over-the-counter medication costs ($11 billion) ⁵ . This is an underestimate of true costs since neither direct costs for non-migraine headache disorders (e.g. chronic daily headache) nor the costs for over-the-counter medications for all headache disorders (which may total $1 billion ⁶) are included in this total. All other data were derived from sources as cited.
