Overview
Migraine is a neurological disease characterized by recurrent moderate to severe headaches, typically occurring on one side of the head. It is often accompanied by nausea, vomiting, sensitivity to light and noise, and physical exhaustion. The exact cause of migraine is unknown, but it is believed to be related to a combination of genetic and environmental factors, such as changes in the brain’s chemical balance and/or fluctuations in hormone levels, as well as lifestyle choices such as stress, poor sleep, and certain foods. Research has shown that the pathophysiology of migraine involves the activation of pain-sensitive nerve fibers, the release of inflammatory mediators and neurogenic inflammation, the alteration of brain signals or neural pathways, and the increased size or presence of trigeminal nerve fibers in the brain. Understanding the underlying pathophysiology of migraine is important for the development of more effective treatments to help reduce symptoms and prevent recurrence.
