Causes and Symptoms of Brain Aneurysm
“An estimated 6 million people in the United States have an unruptured brain aneurysm, or 1 in 50 people” (Brain Aneurysm Foundation 2011). First of all, what is Brain Aneurysm? A brain (cerebral) aneurysm is a bulging, weak area in the wall of an artery that supplies blood to the brain. In most cases, a brain aneurysm causes no symptoms and goes unnoticed. In rare cases, the brain aneurysm ruptures, releasing blood into the skull and causing a “stroke” (Webmd staff 2011). When a brain aneurysm ruptures, the result is called a subarachnoid hemorrhage. Depending on the severity of the hemorrhage, brain damage or death may result. The most common location for brain aneurysms is in the network of blood vessels at the base of the brain called the “circle of Willis.” I think the basic idea here is that what happens in brain aneurysm is that a weak spot develops in the blood vessel which causes blood rupture. I’m really interested in this topic because I’m taking Human Biology right now and my instructor just finished discussing to us what a brain aneurysm is. Well, I think we all have an idea of what a brain aneurysm is so let’s get to the causes and symptoms of Brain Aneurysm.
A person may inherit the tendency to form aneurysms, or aneurysms may develop because of hardening of the arteries (atherosclerosis) and aging. Some risk factors that can lead to brain aneurysms can be controlled, and others can't. The following risk factors may increase your risk of developing an aneurysm or, if you already have an aneurysm, may increase your risk of rupturing it. First is gender, women are likely to develop a brain aneurysm or to suffer a subarachnoid hemorrhage. Another factor is family history; People who have a family history of brain aneurysms are more likely to have an aneurysm than those who don't. Next is hypertension, The risk of subarachnoid hemorrhage is greater in people with a...
