What is the cause of migraine?

What we know: Migraine is inherited due to family genetics. We also are aware that sufferers are sensitive to external and internal triggers which set off glutamate receptors in the brain. The process results in electrical/chemical reactions in brainstem and ultimately parts of brain with release of a series of chemicals that cause pain and to a lesser extent blood vessel changes.

Response to stress: Migraine is the way the body reacts to a stress state. It is a familial trait that is very common. Often triggered by the onset of puberty or by head injury or allergic reactions. Hormone sensitive in women, occasion triggers include certain foods and wine. Life long risk but manageable.

Not really: What creates a migraine is still not understood, although evidence is pointing to altered blood flow in the brain as the probable culprit. What causes this altered blood flow is even less understood, as many forms of migraine exist, and many many triggers for migraines have been noted. Each person has a different set of triggers and symptoms. This is what makes migraines so difficult to treat.
