CLUSTER HEADACHE
DESCRIPTION |
|
|
Cluster headaches have been known as
histamine headaches, red migraines, and Horton's disease, among
others. The constant factor is the pain, which transcends by far the
distress of the more common tension-type headache or even that of a
migraine headache.
Cluster headaches afflict less than 0.5% of the population and
predominantly affect men; approximately 80% of sufferers are male.
Onset typically occurs in the late 20s, but there is no absolute age
restriction. Approximately 80% of cluster headaches are classified
as episodic; the remaining 20% are considered chronic. Both display
the same symptoms. However, episodic cluster headaches occur during
1- to 5-month periods followed by 6- to 24-month attack-free, or
remission, periods. There is no such reprieve for chronic cluster
headache sufferers. |
