The Impact of Shift Work on Migraine: A Case Series and Narrative Review.

In the 2 cases presented, shift work appeared to be associated with chronification of migraine and higher headache-related disability despite optimal headache management and good patient adherence. A switch to only day shifts promoted transition to an episodic, less disabling pattern of migraine. It is clinically important to take a detailed sleep history in headache patients, and when appropriate, provide support for workplace accommodations. Further larger-scale, rigorous studies are needed to more clearly delineate the relationship between shift work and migraine.
