By definition, CDH refers to headache frequency of >15 days per month with duration of >4 hours per day (if untreated), and is classified as chronic migraine, chronic tension-type headache, new daily persistent headache and hemicrania continua. Patients with CDH are frequently comorbid with psychiatric disorders and medication overuse, leading to therapeutic hindrance.
