Primary headache disorders are those in which headache is the predominant clinical feature and there is no obvious underlying structural, genetic, or metabolic cause. Chapter 51 reviews the common primary headache disorders of migraine, tension-type headache, and chronic daily headache. The present chapter reviews less common primary headache disorders, such as the trigeminal autonomic cephalgias (TACs) and headaches with certain triggers. A careful history, physical examination, and additional testing are often necessary to rule out a secondary cause. Red flag symptoms for secondary causes are reviewed in Chapter 50.
