The newly released version of the Global Burden of Disease (GBD 2010) ranks migraine between the most disabling diseases, the first among neurological ones, with a two-fold increase with respect to the previous GBD 2000 version. Almost 3 % of worldwide disability attributable to a specific disease, in terms of years lived with a disability, is due to migraine. The public health impact of migraine and headache disorders is thus a consolidated fact; however, further research is needed to provide stronger recognition of and policy actions for headache disorders in general, and in particular with regard to chronic forms of headache.
