NR 565 Week 4 Study Guide NR 565 Week 4 Chapter 35: Chronic Migraine and Cluster Headache Chronic daily headache headaches 15 or more days a month for longer than 3 months  Chronic daily headaches (CDH) can be divided into five subtypes: o chronic tension-type headache o chronic migraine o hemicrania continua (Not in the study guide = not covered in depth)  rare disorder that responds completely to indomethacin and to nothing else. Indomethacin (Indocin) 75 to 150 mg is given daily; doses up to 200 mg daily may be needed. Referral to a neurologist is recommended. o medication-overuse headache o new daily persistent headache.  Use of drugs for acute headache treatment more than 9 days a month is associated with increased risk of chronic daily headaches.  Medication-overuse is addressed later Pathophysiology: Patho of CDH is often unclear and of mixed origin.  There is a clear difference between chronic migraine and hemicrania continua (Not in the study guide = not covered).  The boundary between chronic tension-type headache and chronic migraine is less clear and may require a neurology referral for treatment. The term chronic migraine refers to CDH that starts as episodic migraine (less than 15 days a month) that transforms into a chronic pattern of greater than 15 days a month of migraine headache  It was formerly called “transformed migraine.”  The initial migraines have the pathogenesis of migraine discussed earlier
