The classification of headaches has a rich history. The first recorded system that resembles the modern ones was published by Thomas Willis, in De Cephalagia in 1672. In 1787 Christian Baur generally divided headaches into idiopathic (primary headaches) and symptomatic (secondary ones), and defined 84 categories. Today headaches are most thoroughly classified by the International Headache Society's, International Classification of Headache Disorders (ICHD), which published the second edition in 2004. This classification is accepted by the WHO
