Migraine is a common neurological condition occurring in at least 15 to 20 percent of the population and in up to 50 percent of women.

Classic migraine starts with visual symptoms (often zigzag lines, colored lights or flashes of light expanding to one side of your vision over 10 to 30 minutes), followed by a single-sided pounding, severe headache. The headache may be associated with nausea, vomiting, and light sensitivity. Sometimes visual symptoms and even neurologic dysfunction may occur without the headache. These are called “migraine variant.”

Common migraine may cause only a headache felt on both sides of the head. This form of migraine may be responsible for the headaches that many people may have attributed to tension, stress, or sinus pain.
