About Migraine Visual Aura
Aura symptoms are often described as a warning sign that a migraine is about to appear and typically last between 20-40 minutes. Visual symptoms are the most common type of aura experiences. Migraine visual aura can present in various forms, and the visual distortions usually start small and progress across your vision over times. While it is not entirely understood why sensory disturbances happen in some patients, there is evidence that the migraine aura may be caused by an electrical or chemical wave that moves across the brain, affecting areas that process sensory signals, speech, and movement.
Symptoms of Migraine Visual Aura
Aura symptoms usually occur before other migraine symptoms like intense head pain, nausea, and sensitivity to light/sound.
Symptoms of migraine visual aura may include:
- Blind spots (scotomas), that are sometimes outlined by simple geometric designs
- Zigzag lines that gradually float across your visual field
- Shimmering spots or stars
- Changes to vision or vision loss
- Flashes of light
Risk Factors for Migraine Visual Aura
Visual aura associated with migraine tends to be more common in women and in people with a family history of migraines.
In addition to the demographic risks above, the following factors may trigger migraine with aura:
- Certain foods
- Certain medications
- Too much or too little sleep
