Cluster headaches are rare, extremely painful and debilitating [[headache]]s that occur in groups or clusters. Often appearing during seasonal changes. They may also be described as suicide headaches, a reference to the excruciating pain and resulting desperation that has culminated in actual [[suicide]]. Cluster headaches are classified as [[vascular headache]]s. The intense pain is caused by the [[dilation]] of blood vessels which creates pressure on the [[trigeminal nerve]]. While this process is the immediate cause of the pain, the [[etiology]] (underlying cause or causes) is not fully understood. Differential of cluster headache usually involves syndromes that manifest as unilateral headache, brief but frequent attacks. Such syndromes include the following: [[Chronic paroxysmal hemicrania]] (CPH) , Short-lasting unilateral neuralgiform headache attacks''',''' [[Trigeminal neuralgia]], primary stabbing [[headache]], and headache associated with an underlying intracranial lesion. Patients with cluster headaches usually have an underlying secondary cause of headaches such as structural brain lesion, TBI and genetic predisposition that may increase the risk of cluster headache. Cluster headache is one of the most common trigeminal autonomic cephalalgias. It is a life long condition and usually results in reduced quality of life and marked functional disability. Although, the frequency of episodes usually decrease with age, 80% of patients continue to experience the attacks even after 15 years of onset. Diagnostic criteria for cluster headache require the following as per ICHD-3: International Classification of Headache Disorders, 3rd edition. Cluster headache sufferers typically experience very severe headaches of a piercing quality near one [[eye]] or [[temple]] that last for fifteen minutes to three hours with some lasting days (rarely more than three days). The headaches are typically [[wiktionary:unilateral|unilateral]] and rarely change sides during the same cycle (see episodic). Cluster headaches have a characteristic circadian periodicity and usually present with autonomic symptoms. Neuro-imaging with an magnetic resonance imaging (MRI) scan with and without contrast is preferred to non-contrast computed tomography (CT) scan. MRI is usually indicated to rule out underlying structural brain lesion or to evaluate brain and pituitary gland in patient presenting with typical features or highly suspicious of cluster headache. Cluster headache treatment is generally divided into acute therapy or abortive therapy focused at aborting individual attacks and preventive or prophylactic therapy aimed at preventing recurrent attacks during the cluster period. Cluster headaches often go undiagnosed for many years, being confused with migraine or other causes of headache.

Historical Perspective
Cluster headaches have been called by several other names in the past including Erythroprosopalgia of Bing, ciliary neuralgia, migrainous neuralgia, erythromelagia of the head, Horton's headache, histaminic cephalalgia, petrosal neuralgia, sphenopalatine neuralgia, Vidian neuralgia, Sluder's neuralgia, and hemicrania angioparalyticia. In 1952, cluster headache was named by American physician E. Charles Kunkle. In 1998, cluster headache was established as a separate entity by International Classification of Headache Disorders (ICHD-I). In 2004, restlessness/agitation was added with the ICHD-II revision.
