title: Primary Headache Disorders: Focus on Migraine.
abstract: Migraine is the most common disabling headache disorder.Most patients with disabling tension-type headache are likely to have migraine and accordingly respond to treatments efficacious in migraine.Individuals are genetically predisposed to experiencing recurrent migraine.Evidence supports migraine to be a primarily neural and not vascular mediated disorder.1-2% of the population have chronic daily headache associated with acute-relief medication overuse; the majority are migraineurs.The presence of acute-relief medication overuse renders preventative medication less adequately efficacious.
