Types of Cluster Headaches

Topic Overview

There are 2 types of cluster headaches :

The cluster periods are followed by headache-free periods (remissions) of 6 months or more. About 90 out of 100 people who have cluster headaches have episodic cluster headaches. 1
  • Chronic cluster headaches are those that occur during a period of at least 12 months without a headache-free period (remission) or when remissions last less than one month. 2 About 10 out of 100 people who have cluster headaches have chronic cluster headaches. 1
