In the previous podcast, we discussed the general approach to headache, red flags, and clues to help distinguish primary from secondary headaches. Because migraine is such a common neurological disorder affecting over 4,000,000 Canadians and resulting in significant social and economic impact, we will discuss acute and chronic migraine in some detail over the course of the next three podcasts. In this podcast we discuss the diagnostic criteria for migraine, the general principles of acute migraine management, and specific therapies for acute migraine. In the next two podcasts we will discuss migraine prophylaxis and the challenging condition of chronic migraine.With us again is Dr. Werner Becker, professor of Neurology at the University of Calgary. Dr. Becker is also the senior author of the Canadian Headache Society guidelines for acute migraine treatment and for prophylactic migraine treatment. Dr. Becker has no disclosures.
