Brain Stroke

A stroke may be a “brain attack”. It occurs when blood flow to a neighborhood of brain is stop. When this happens, brain cells are bereft of oxygen and start to die. When brain cells die during a stroke, abilities controlled by that area of the brain like memory and muscle control are lost. Stroke may be a disease that affects the arteries resulting in and within the brain. It’s the No. 5 explanation for death and a number one explanation for disability within the us. A stroke occurs when a vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts (or ruptures). When that happens, a part of the brain cannot get the blood (and oxygen) it needs, so it and brain cells die
