Neurobiology of migraine

Migraine - an episodic headache - affects more than 10% of the general population. Despite recent progress, drug therapy for preventing and treating migraine remains unsatisfactory for many patients. One problem that slows the development of new therapeutic approaches is our limited understanding of migraine neurobiology. Activation of the trigeminovascular system is a central step in the development of migraine. However, two main issues remain incompletely understood: the primary cause of migraine, leading to activation of the trigeminovascular system, and the mechanisms of pain generation after its activation.
