Types of Cluster Headaches

Topic Overview

There are 2 types of cluster headaches:

  • Episodic cluster headaches are the most common type of cluster headaches. People with episodic cluster headaches have cluster periods of 1 to 3 months when they are prone to having headaches. The cluster periods are followed by headache-free periods (remissions) of 6 months or more. About 90% of 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% of people who have cluster headaches have chronic cluster headaches.3
