What is a migraine aura?
The two most prevalent types of migraine headache are migraine without aura and migraine with aura. Approximately 20 percent of migraine sufferers experience aura during their migraine attacks. The aura is comprised of neurological symptoms that most often include visual disturbances, such as flashing lights or lines, and may also include dizziness, numbness, or tingling that usually precedes the headache.
