Migraine is a common primary headache disorder characterised by severe, pulsating, mostly unilateral headaches accompanied by vomiting, nausea, and autonomic dysfunctions. In the United States alone, about 18% of the female population and 6% of the male population have migraine headaches. Some people experience transient neurological symptoms before or during the headache that are most often visual, such as seeing zigzag lines or flash spots, but might also include sensory or motor symptoms.
