| Stroke A stroke occurs when a blood vessel inside the brain is blocked by a blood clot (ischemic stroke) or bursts (hemorrhagic stroke). When ischemic stroke occurs, there is a reduction of blood flow to the brain. As a result, that part of the brain will be deprived of oxygen and suffer from neuronal damage. When hemorrhagic stroke occurs, blood leaks out of the blood vessel after the vessel ruptures. Similar to ischemic strokes, hemorrhagic strokes interrupt the blood flow in brain tissue. In addition, further neuronal damage is caused by the blood leaked into the surrounding brain tissue. As a result, that damaged portion of the brain could not longer control the part of the part it once used to control. If you are experiencing symptoms of a stroke, immediately call 911 for emergency medical help for treatment to limit the amount of permanent damage to your brain. |
