A Migraine Headache is a very painful type of headache. Migraine is a chronic disorder characterized by recurrent moderate to severe headaches often in association with a number of autonomic nervous system symptoms.
People who get migraines often describe the pain as pulsing or throbbing in one area of the head. During migraines, people are typically very sensitive to light and sound. They may also become nauseated and vomit.
Migraines are three times more common in women than in men. Some people can tell when they are about to have a migraine because they see flashing lights, zigzag lines or they temporarily lose their vision.
Doctors used to believe migraines were linked to the opening and narrowing of blood vessels in the head. Now, they believe the cause is related to genes that control the activity of some brain cells. The exact mechanisms of migraines are not known. It is, however, believed to be a neurovascular disorder.
Globally, more than 10% of the population is affected by migraines at some point in life.
