There are two types of blockages that can lead to ischemic stroke: a cerebral embolism and cerebral thrombosis.Ī cerebral embolism (often referred to as embolic stroke) occurs when a blood clot forms in another part of the body - often the heart or arteries in the upper chest and neck - and moves through the bloodstream until it hits an artery too narrow to let it pass. Pieces of plaque breaking off and blocking a blood vessel can also cause them. Blood clots or severely reduced blow flow to the brain causes these blockages.
