Transformed Migraine Is a Cause of Chronic Daily Headaches

Abstract: Chronic daily headaches (CDH) consist of episodes of head pain occurring daily; more than 15 days each month; often associated with a history of migraine, with or without aura; or with a history of tension-type headaches occurring alone or both occurring together. Chronic daily headaches are frequently associated with rebound headaches after ergotamine, barbiturate, caffeine, and analgesic abuse. We previously reported that migraineurs with typical intermittent headaches exhibited excessive cerebral cortical v… Show more

“…The implication of analgesic overuse has been considered in chronic headache [9][10][11][12][13][14][15][16], although we do not have common diagnostic criteria for classifying rebound headache. In adults, the percentages of analgesic overuse range from 72% [17] to 87% [14] to 91% [18]. The prevalence of medication abuse in a general CDH population is 25% [19].…”

“…This condition affects approximately 3% to 5% of the general adult population 2,3 and is responsible for up to 80% of new patient complaints in headache‐specialty clinics 4,5 . Most cases of CDH arise from episodic migraine or tension‐type headaches that gradually transform into daily or near‐daily headaches 6,7 . Medications commonly used to treat headache, such as acetaminophen, aspirin, nonsteroidal anti‐inflammatory drugs, triptans, narcotics, or barbiturates, can have problematic side effects and paradoxically contribute to the transformation of episodic headaches to CDH 8–14 .…”
