Stroke are either ischemic, caused by partial or complete occlusions of a cerebral blood vessel by cerebral thrombosis or embolism or hemorrhage (leakage of blood from a vessel causes compression of brain tissue and spasm of adjacent vessels).

A stroke is a result of low oxygen or low blood flow to an area of the brain this can happen from a blood clot causing a blockage of blood flow (ischemic stroke), a leak in a blood vessel, or a burst blood vessel (hemorrhagic stroke) blood carries oxygen to the tissues of the brain, and when blood .
