Migraine is a neurological syndrome characterized by altered bodily perceptions, headaches, and nausea more common to women than men. Migraine is a very painful type of headache with throbbing or pulsating pain in one area of brain caused by a combination of enlargement of blood vessels and the release of chemicals from nerve fibers that surround the blood vessels and is often accompanied by nausea, vomiting, and extreme sensitivity to light and sound.

 

There is no cure or medications for migraine headache but the drugs can help reduce the frequency and severity of migraines. There are many drugs specifically designed to treat migraine which are given below
