Although the precise cause of migraine headaches is unknown, a key element is blood flow changes in the brain. People who get migraine headaches appear to have blood vessels that overreact to various triggers. One theory which might explain these changes suggests that the nervous system responds to a trigger by creating a spasm in the nerve-rich arteries at the base of the brain. The spasm closes down or constricts several arteries supplying blood to the brain, including the scalp artery and the carotid or neck arteries. As these arteries constrict, the flow of blood to the brain is reduced. At the same time, blood-clotting particles called platelets clump together, a process which is believed to release a chemical called serotonin. Serotonin acts as a powerful constrictor of arteries, further reducing the blood supply to the brain. Reduced blood flow |
