Abstract
BACKGROUND: A systematic approach to the diagnosis of primary and secondary headache disorders requires the measurement of the frequency and the duration of headache. OBJECTIVE: This article presents thumbnail sketches of the most important headache subtypes and discusses some of the new revisions and headache types included in the International Classification of Headache Disorders (ICHD 2). DISCUSSION: The clinical features that distinguish secondary headaches requiring urgent investigation (red flags) from those that can be more safely monitored (blue flags) are discussed.
