Migraines and Cluster Headaches

The International Headache Society has published a detailed classification of primary headaches, including migraine. Chronic migraine is defined as the occurrence of 15 or more headache days per month, with migraine features present on at least eight of these days. Episodic migraine is the occurrence of 4 to 14 migraine days per month. Cluster headache, which is often misdiagnosed as migraine, is the most common of the primary headache disorders known as trigeminal autonomic cephalalgias; this type of headache derives its name from the fact that the attacks occur in cyclical patterns, or clusters.[4]
