CVA (Cerebrovascular Accident), commonly known as a stroke, is a cardiovascular disease affecting the blood vessels that supply blood to the brain. A stroke occurs when a blood vessel that brings oxygen and nutrients to the brain bursts (hemorrhagic) or is clogged by a blood clot or some other mass (ischemic). When a vessel bursts or is clogged it deprives the brain of blood and oxygen it needs. If the brain does not receive the nutrients supplied by the blood after several minutes the cells and tissue begin to die, causing irreversible damage.
Hemorrhagic stroke accounts for about 17 percent of stroke cases. It results from a weakened vessel that ruptures and bleeds into the surrounding brain. The blood accumulates and compresses the surrounding brain tissue.
Ischemic stroke accounts for about 83 percent of all cases. It results from an obstruction, typically a blood clot. These clots are called a cerebral thrombus (a blood clot that develops in the clogged part of the vessel) or a cerebral embolism (a blood clot that forms at another location in the circulatory system then breaks loose, enters the bloodstream and travels through the brain's blood vessels until it reaches vessels too small to let it pass).
The effects of a stroke can vary from case to case depending on location of the obstruction. If the obstruction is on the right side of the brain; vision problems, paralysis on the left side of the body (including left side of face), memory loss, and a quick, inquisitive behavior style could all be signs and symptoms of a right hemisphere obstruction. If the obstruction is on the left side; aphasia (speech problems), paralysis on the right side of the body (including right side of face), memory loss, and a slow, cautious behavior style could all be signs and symptoms of a left hemisphere obstruction. .
There are many risk factors associated with stroke. The more risk factors a person has, the greater the chance that he or she will have a stroke.
