Brain Aneurysm :
A brain aneurysm, also known as a cerebral aneurysm is an area of dilated blood vessel inside the brain as a result of weakness in a part of its wall. These enlargements can continue growing for months to years and then rupture, forming a hemorrhagic stroke, which is usually fatal. Several factors include high blood pressure, smoking, a family history, and several other genetic predispositions. Symptoms often do not develop until the rupture of an aneurysm, although people have reported, in previous months, headaches and vision changes or neck pain. Often with a rupture is associated with a "thunderclap" headache which is recognized as severe and abrupt onset. Imaging studies normally are the basis for diagnosis.
The treatment will depend on the size and location of the aneurysm. Small, unruptured aneurysms can be followed. However, a larger or symptomatic one can be operated on with surgical clipping or endovascular coiling to prevent rupture. In fact, very well known is the fact that the early detection becomes important because timely intervention will save those who would have otherwise died from complications of bleeding before being diagnosed. A healthy lifestyle can lessen the possibilities of developing this kind of aneurysm because of managing certain risk factors.
