Stroke is a medical condition in which poor blood flow to a part of the brain causes cell death. [5] There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. [5] Both cause parts of the brain to stop functioning properly. [5]

A stroke is the rapid loss of brain function(s) due to disturbance in the blood supply to the brain. This can happen because of ischemia (lack of blood flow) caused by blockage ( thrombosis , arterial embolism ), or a haemorrhage (leakage of blood).

Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
