Migraine is believed to be a neurological disease. Typical symptoms include intense, one-sided headache, nausea and sensitivity to light or sound. It is not simply a bad headache. Though these symptoms are typical, they are not universal. Sometimes migraine symptoms do not include pain at all, for example. Sometimes the headache is on both sides of the head, not just one side.Back to M
The exact cause is still unknown, though it is now believed to be genetically based. We know quite a bit about the chain reaction, but the actual cause may lie deep in the brain itself.
The things that are often thought to cause headache or related symptoms are more technically called triggers. Certain types of food, environmental changes, or changes in sleep patterns, for example, can start the chain reaction in people who are predisposed.
Treatment varies from person to person. Some find preventative medication helpful, while others use abortive once the headache starts. Many non-drug remedies have also been successful, including diet, massage or biofeedback. For more, be sure to explore this site using the navigation bar to the left.
