The prevalence, disability, progression, and treatment needs associated with chronic migraine (CM) mandate epidemiological, clinical, and basic research to better understand the clinical course of this disorder and to facilitate development of more effective therapies. Such efforts have been significantly impeded by lack of agreement within the headache specialist community of the most appropriate diagnostic criteria for CM. ⋯ The proposed criteria are guided by the aims of accurately characterizing patients with migraine who develop primary chronic daily headache, reflecting the large numbers of patients with CM in clinical practice, and facilitating research into a disorder that is an academic and clinical priority.

Medication overuse headache (MOH) affects between 1% and 2% of the general population but is present in up to 50% of patients seen in headache centers. There are currently no internationally accepted guidelines for treatment of MOH. ⋯ Increased focus on MOH is extremely important, as MOH both can and should be treated and prevented. MOH is thus a diagnosis that should be considered in all chronic headache patients as the very first step in their management strategy. In the general population, prevention campaigns against MOH are essential to minimize chronic pain disability.

To conduct a systematic review to evaluate persistence to and switching of triptan therapy for the acute treatment of migraine. ⋯ Triptans can be a valuable option for acute treatment of migraine. However, studies have shown that treatment persistence is low. This, along with frequent switching behaviors, suggests that a significant unmet clinical need remains despite the wide availability of triptans.

Migraine and neck pain can be critical causes of disability. The contribution of neck pain for the overall disability of individuals with migraine remains unknown. ⋯ Neck pain significantly adds to the overall disability of individuals with episodic and chronic migraine.

Migraine increases the risk of stroke, particularly in young and otherwise healthy adults. Being the most frequent neurological condition, migraine prevalence is on a par with that of other common stroke risk factors, such as diabetes or hypertension. ⋯ The severe stroke phenotype in migraine mutant mice can be prevented by suppressing spreading depolarization. If confirmed in the clinical setting, inhibiting spreading depolarization might protect migraineurs at stroke risk as well as decrease attacks of migraine.
