title: [Societal impact of migraine chronification].
abstract: Migraine is a common neurological disorder that produces substantial disability for sufferers. Chronic migraine (≥ 15 headache days/month; CM) was significantly more disabling than episodic migraine (< 15 headache days/month; EM). CM was associated with greater impairment of occupational and social aspects of quality of life. Lost productivity time was substantially higher among CM participants than persons with EM. Full time employment was lower in CM participants because of medical leave. The medical costs were two or three times higher for CM than EM. These results suggest that migraine chronification is associated with substantial economic burden.
