Migraines are "vascular" headaches, meaning that their source is the contraction and dilation of blood vessels. Originally, vascular headaches were thought to be caused solely by changes in the dilation of blood vessels. More recent research, however, indicates that the nervous system and genetics contribute to the problem.
The exact causes of vascular headaches are a mystery. Some theories hold that nerve fibers surrounding blood vessels give off chemicals that cause the blood vessels to dilate or constrict. Others suggest that brain neuron activity sets off a reaction in the brain stem that causes the facial arteries to become inflamed. Yet another suggests that the brain's blood vessels spasm, reducing Some researchers have suggested that migraines can be traced to an overactive nervous system. When the nervous system detects certain substances, sensations or other triggers, it sets in motion a series of brain activity that leads to blood vessel dilation or contraction.
