Primary headache disorders are those in which the headache is the primary feature of the disorder and is not otherwise explained by a structural, genetic, or metabolic cause. This chapter reviews the clinical features, diagnosis, and treatment of common primary headache disorders, including migraine, tension-type, and chronic daily headaches. Migraine usually starts during adolescence, and 90% of patients with migraine have their first attack by age 40 years. In childhood, there is a slight male predominance, but after puberty, a 3:1 female predominance is established. The highest reported prevalence of migraine is in patients who are 30 to 39 years old. |
