What is Migraine? Migraine is a neurological disease characterized by episodic moderate to severe headaches with associated other neurological symptoms predominately autonomic symptoms. Typically, the headache affects one side of the head, is pulsating in nature, and can last up to 3 days.
The word cluster is used because these headaches typically come in groups or bunches. A person may have several headaches a day for weeks or months, usually separated by headache-free periods of varying duration. Many more people have migraine or tension headaches than cluster headaches.
