This chapter provides information on the epidemiology of headache, with major sections devoted to migraine and tension-type headache. The clinical features of each headache type are discussed, and details of International Headache Society (IHS) criteria are described. This is followed by a summary of studies related to the incidence and prevalence, and a description of how headache frequency varies by age, sex, race, and geographic region. The chapter provides a summary of risk factors for headache, in addition to describing triggering factors among headache sufferers. The final section is devoted to a discussion of the impact of headaches, including frequency, severity, and health-related quality of life.Less

There can be no doubt that migraine is associated with changes in the cephalic (cerebral and non-cerebral) circulation; the doubts, however, concern the cause and nature of such changes. In a majority of migraine patients with ‘aura’, the cerebral blood flow decreases, but in ‘classical’ migraine patients both decreases and increases have been reported. In the non-cerebral cephalic circulation, vasodilatation and increased pulsations are observed principally on the side of the migraine headache, but the idea of simple vasodilatation is paradoxical to the facial pallor and laxity of tissues usually noticed during the headache. To resolve this paradox, Heyck suggested that vasodilatation involves cephalic arteriovenous anastomoses.Less
