Every day we hear or see information about stroke and the warning signs, as well as what we can do to prevent it. So let's talk about strokes and what they are, where they come from and possible treatments. We will discuss CVAs and TIAs and briefly review the different types of strokes. We will address the importance of this topic and over time we will see how strokes can affect the daily lives of many Americans. I will walk you through the facts and give you some personal experiences.Cerebrovascular Accident: The medical term for a stroke. A stroke occurs when blood clots and forms blockages in an artery or blood vessel that ruptures, disturbing blood flow to an area of the brain. With both of these things the brain cells start to die and brain damage occurs. When this happens, the abilities controlled by that area of the brain cease, this includes but is not limited to; Word, movement and even memory. The effects depend on where the stroke occurs and how much of the brain is damaged. Someone who suffers a small stroke may have only minor problems such as weakness in a ligament. Those who suffer larger attacks may become paralyzed on that side or lose the ability to speak. Recovery from strokes is possible. However, more than 2/3 of stroke survivors will have some type of permanent disability. There are 7 types of stroke; one of the most important ones I will talk about will be the TIA. Ischemic stroke: In everyday life, blood clotting is beneficial. When you bleed from a wound, blood clots work to slow and eventually stop the bleeding. In the event of a stroke, however, blood clots are dangerous because they can block arteries and stop blood flow, a process called ischemia. An ischemic stroke… half of the paper… those caused by the rupture or “burst” of a blood vessel in the brain are called hemorrhagic strokes. The medical word for this type of rupture is hemorrhage. Hemorrhages can be caused by a number of disorders that affect the blood vessels, including chronic hypertension and brain aneurysms. An aneurysm is a weak or thin spot on the wall of a blood vessel. These weaknesses are usually present at birth. Aneurysms develop over several years and usually cause no detectable problems until they rupture. There are two types of hemorrhagic stroke: subarachnoid and intracerebral. TIA: transient ischemic attack is also considered a mini-stroke. With stroke-like symptoms lasting less than 24 hours before disappearing, although TIAs generally do not cause any permanent damage, they are a serious warning sign of a stroke and should not be ignored.
