Headache Occurring on More Days Than Not
The term “chronic daily headache” (CDH) is commonly used to refer to primary headache that occurs on at least 15 days per month (more days than not). CDH is common, and associated with social, behavioral, and occupational disability. In recent years, the concept of disease modification has been applied to migraine, with an emphasis on the identification of factors that might prevent disease progression. The early recognition of high-risk patients and the utilization of a multidisciplinary treatment plan while headaches are still in the episodic phase appear to be critical aspects in preventing or minimizing progression and resultant disability. In this chapter, risk factors for CDH will be reviewed and principles of preventing headache chronification, including the initiation of preventive medication and behavioral treatment, the recognition of medication overuse, and the implementation of lifestyle modifications, will be discussed. Areas of ongoing research will also be addressed.
