Currently a prolonged non-hemiplegic migraine with aura (NHMA) is classified as ‘persistent aura without infarction’ if the duration is equal or longer than 7 days. Those lasting more than 60 min and less than 7 days are classified as ‘probable migraine with aura (prolonged aura)’.
What happens in the brain during a migraine aura?
The result: The brain produces an outsize reaction to the trigger, its electrical system (mis)firing on all cylinders. This electrical activity causes a change in blood flow to the brain, which in turn affects the brain’s nerves, causing pain.
Why is migraine with aura a stroke risk?
People who experience aura might have increased tendency to form blood clots due to temporarily narrowed blood vessels, which can predispose them to stroke, Tietjen said, which studies suggest may increase stroke risk compared to women in that age group who don’t have migraines.
