Unlike many other types of headaches,
cluster headaches are more common in men than in
women. These headaches are rare in children younger than age 10. Cluster
headaches are not common. About 4 out of 1,000 people suffer from them.1
This type of headache may be
genetic, because your risk of getting cluster headaches
is higher if you have a parent or sibling who has the condition. Cluster
headaches usually start when you are in your 30s and 40s. But many men
have cluster headache cycles while they are still in their 20s.
About 9 out of 10 people with cluster headaches get them only
occasionally (episodic). One person out of 10 has chronic
cluster headaches.2 Chronic cluster headaches are
defined as headache cycles that happen one after another for longer than 1 year
without stopping (being in remission) at all or only stopping for less than a
month before a new headache starts.3
