Summary points

  • Cluster headache is an excruciatingly painful primary headache disorder, which places an exceptional burden on those affected

  • Attacks are one sided, generally last 15 minutes to three hours, and have a characteristic set of cranial autonomic features, which are accompanied by agitation

  • Attacks occur from once every other day to eight times daily, in bouts that last several weeks, usually with complete remission between bouts

  • Treat acute attacks with high flow oxygen (12 L/min for at least 15 minutes) or parenteral triptans (or both), such as subcutaneous sumatriptan 6 mg, unless contraindicated

  • High doses of verapamil are often necessary as preventive treatment; electrocardiographic monitoring is mandatory when escalating doses

Despite this remarkably prescient view, and the extreme and stereotyped nature of its presentation, cluster headache is still commonly misdiagnosed. Without a clear diagnosis, affected patients can wait many years before receiving adequate help, and they often endure unnecessary and unhelpful attempts at treatment before gaining any relief.2

Patients describe the pain of a single attack as being worse than anything else they have experienced, including childbirth. Many endure repeated attacks, lasting up to three hours, every single day. The severity of the pain has earned it the sobriquet “suicide headache,” although in our experience this is a rare occurrence in this exceptional patient group.

The management of this condition differs from that of other headache disorders. This article will review the clinical entity of cluster headache by highlighting its unique and defining characteristics as an aid to correct diagnosis, before critically appraising …
