A stroke, sometimes referred to as a cerebrovascular accident (CVA), cerebrovascular insult (CVI), or colloquially brain attack is the loss of brain function due to a disturbance in the blood supply to the brain.

This disturbance is due to either ischemia (lack of blood flow) or hemorrhage.

Ischemia is caused by either blockage of a blood vessel via thrombosis or arterial embolism, or by systemic hypoperfusion.

Hemorrhagic stroke is caused by bleeding of blood vessels of the brain, either directly into the brain parenchyma or into the subarachnoid space surrounding brain tissue.
