An embolic stroke occurs when a blood clot moves to the brain and prevents blood flow, states Healthline. These blood clots typically travel upwards from the neck and upper chest.
Artery wall plaque, an abnormal heartbeat, air bubbles and fat globules can cause an embolic stroke, explains Healthline. Symptoms include confusion, loss of balance, loss of vision, difficulty understanding or speaking words, and numbness in the face, a leg or an arm. Treatment for an embolic stroke involves restoring blood flow to the brain with medications that rupture blood clots. Risk factors for embolic stroke include high blood pressure, high cholesterol, certain autoimmune diseases, smoking, and abusing drugs or alcohol.
