title: Cluster headache in black patients. A report of 7 cases.
abstract: Cluster headache is an uncommon form of headache syndrome. It is characterised by paroxysms of severe unilateral head pain typically involving the orbit. There are often associated autonomic changes on the affected side such as lacrimation, nasal congestion and Horner's syndrome. Apart from episodic cluster headache, various subtypes such as chronic cluster headache, cluster headache variant and chronic paroxysmal hemicrania have been identified. There have been few reports of the incidence and clinical features of cluster headache in blacks; 7 black patients with various types of cluster headache are described.
