Type of disease: Rare conditions
Cluster headaches are a form of headache notable for their extreme pain and their pattern of occurring in “clusters”, usually at the same time(s) of the day for several weeks. A cluster headache usually begins suddenly with excruciating pain on one side of the head, often behind or around one eye. In some individuals, it may be preceded by a migraine-like “aura.” The pain usually peaks over the next 5 to 10 minutes, and then continues at that intensity for up to an hour or two before going away. Cluster headaches generally begin between the ages of 20 and 50, although the syndrome can also start in childhood or late in life. Males are much more likely than females to develop cluster headaches. Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
