ABSTRACT
This article discusses two theories about the cause of migraine. The first theory assumes that a genetic defect causes an abnormal release of neurotransmitters in the brain. This leads to a state of hyperexcitability in the brain and an abnormal response to one or more stimulating factors. The second theory involves the mechanisms in the brain that control pain and blood flow. These mechanisms may be triggered to malfunction, causing nerve cells to become hypersensitive and creating what one scientist calls a nerve storm in your head. As such, the brain might be considered a migraine generator that is activated by normal input from the environment, such as sounds or smells.
