Migraine (say: my-greyn) is a very common disorder. About 12% of women (12 out 100) and 6% (6 out 100) of men have migraines. It is by far the most common diagnosis in people who see a doctor for their headaches. The headaches are often very severe. Most people get migraines only every once in a while (episodic migraine).
Multiple sclerosis (MS) is a disease of the nervous system (the brain and spinal cord). MS damages the protective coating around nerve cells, called the myelin sheath. This coating helps nerves communicate with each other, and so MS slows down nerve conduction. No one knows what causes it, and there is no completely effective cure.
