About Hemorrhagic Stroke
A individual suffers a stroke when the blood circulation to his or her brain ceases, causing brain cells to die due to decreased blood flow and lack of oxygen. The type of stroke an individual suffers usually is dinstinguished into two groups: ischemic stroke and hemorrhagic stroke. Ischemic stroke occurs when an individual experiences a blockage of blood flow to the brain. This blockage stems from three conditions: (1) thrombosis: the formation of a clot within a blood vessel of the brain or neck; (2) embolism: the movement of a clot from another part of the body to the brain; and (3) stenosis: a severe narrowing of an artery in or leading to the brain.
A hemorrhagic stroke occurs when an individual experiences bleeding in the brain or the spaces surrounding the brain after a blood vessel bursts.
