Cluster headache manifests as an excruciating pain around one eye and/or temple. They can last anywhere from fifteen minutes to several hours, and are usually more intense than migraine or tension headaches. Cluster headache gets its name from the pattern of attacks: they occur in clusters, sometimes at the same time each day for weeks or even months, then disappear for prolonged periods.

During the cluster headache, the person is agitated and may become violent or even suicidal.

Cluster headache is uncommon, especially among women (they make up for it in the migraine category, though). Cluster headaches tend to start in middle age or later, and there is some genetic component.

Prevention of cluster headache

The underlying cause of cluster headaches is not known. Current research indicates that there may be brain, nerve, and vascular etiologies. Identifiable triggers such as alcohol, smoking, or stress should be avoided. Imitrex injections may be helpful.
