Migraine Auras
Before the onset of headache pain, 10% to 20% of migraine sufferers experience a 10- to 60-minute aura. An aura is thought to result from the narrowing (constriction) of blood vessels in the brain. The location of the diminished blood supply determines the specific aura symptoms experienced.
An aura is usually, but not always, visual. Examples of visual aura symptoms include the following:
- silver streaks
- white lights
- light objects appearing excessively bright
- all objects appearing gray or yellow
- distortion of all linear objects
- dancing and moving cobwebs
- moving black veils
- scintillating picket fences
- silver stars
- heat waves
- flashing gold lights
- Fourth of July sparklers
- zigzag streaks of light
- herringbone patterns
- double vision
- blind spots
Auras may also be experienced as numbness and tingling in the face, arms, or legs. Some migraine sufferers experience weakness, slurred speech, or even brief paralysis.
