People who have migraines with aura are more likely to have strokes caused by either a blood clot in the heart (cardio-embolic stroke) or a clot within the brain’s blood vessels (thrombotic stroke), compared to those that don’t have migraines with aura, according to research presented at the American Stroke Association’s International Stroke Conference 2016.
Some people with migraines experience neurological symptoms (aura) such as flashes of light, blind spots, or tingling in the hand or face. In adults, symptoms usually happen before the headache itself. Migraines with aura account for less than 20 percent of all migraines, researchers said.
