Cluster Headaches - Cause
The cause of cluster headaches is not clear. They may be genetic, because you are more likely to develop cluster headaches if a parent or sibling has them.
Cluster headaches may be caused by a problem in an area of the brain called the hypothalamus, although the specific problem or abnormality that triggers cluster headaches is unclear.
