4Causes of Migraines with Aura
Scientists still do not know exactly why auras occur with a migraine. However, they believe that this may result from two possible causes:
– Vascular changes
– Cortical spreading depression: This condition occurs in many neurological diseases when a mechanical or electrical trigger leads to a disturbance in the brain’s electric activity.
Migraines with aura tend to start in the occipital region of the brain, which affects your vision. From this point, it radiates to other brain areas and causes headache pain. [4]
