What is an aneurysm? An aneurysm is a bulge in an artery. Because of a weakness in an artery wall, it "balloons." This makes the artery open to further weakening, and it could burst. Aneurysms can affect any blood vessel. The most important aneurysms affect the biggest artery leaving the heart and the arteries in the brain. Burst aneurysms are dangerous When a brain aneurysm bursts, there is a brain bleed known as a subarachnoid hemorrhage. This medical emergency needs urgent treatment. The chances of survival are worse when treatment is delayed. The National Institute of Neurological Disorders and Stroke say that about 40 percent of people who have a burst brain aneurysm die within the first 24 hours. A quarter will die within 6 months. Survival depends on a number of factors, including age, general health, and how quickly medical care is received. For people who do survive a burst brain aneurysm, the outlook remains serious. It increases the chances of another burst, and there are likely to be complications such as long-term brain damage and nervous disorders. Symptoms of stroke or aneurysm Most strokes are caused by a blocked artery, and produce symptoms such as: One side of the face dropping Inability to lift the arms Weakness or numbness in one arm Slurred speech or inability to talk It is important to call for an ambulance when a stroke is suspected. Other stroke symptoms may include: Complete paralysis of the body along one side Sudden vision disturbance Dizziness Confusion or difficulty understanding other people Loss of balance or coordination Difficulty swallowing Aneurysms that have not burst do not tend to produce symptoms. Symptoms are likely to appear only if the size of the bulge is large. Such an aneurysm has a high risk of bursting. Anyone already diagnosed with a brain aneurysm who develops symptoms should go to a doctor as soon as possible. They may be able to get treatment can prevent a burst. An intact brain aneurysm may produce symptoms such as: Vision problems Pain above or around the eye Weakness or numbness of the face Headaches Loss of balance Speaking difficulties Problems with thinking A burst aneurysm in the brain usually causes: Extreme headache Vomiting Collapse, seizure, or coma Differences between aneurysm and stroke symptoms Aneurysms that have not burst do not generally create symptoms. Instead, this article will look at the difference between symptoms of a burst aneurysm and a common stroke. Sudden headache is the main feature that distinguishes a burst aneurysm from a common stroke caused by a blood clot. Usually within seconds of a brain aneurysm bursting, there is a headache that is as severe as could be imagined. Other signs and symptoms may differ between a burst aneurysm and common stroke. Sudden extreme headache is the one that is noticeably different, however. Risk factors and prevention Two risk factors raise the risk of both stroke and aneurysm: smoking and high blood pressure. A doctor takes the blood pressure of a man High blood pressure can be alleviated by maintaining a healthy lifestyle. Age is also a risk factor for both. Older people are more likely to have an aneurysm or stroke than younger people. Smoking is dangerous for anyone who has an intact aneurysm since it raises the risk of it bursting. Stroke risk factors and prevention A number of risk factors are well-established to lie behind stroke. The biggest preventable risk factors are: Smoking or other tobacco use Lack of physical activity Poor diet Obesity Other risk factors are not preventable, including genetics, such as a family history of heart disease or stroke. Some factors are partly avoidable or manageable, including high cholesterol, high blood pressure, and diabetes. Aneurysm risk factors and prevention The two main risk factors that increase the chances of a brain aneurysm are smoking and high blood pressure. These also raise the risk of an aneurysm bursting. Having both risk factors together also adds to the risk by a greater amount than simply adding together the two individual factors. Prevention therefore means not starting smoking, or stopping it, and controlling blood pressure. Other risk factors that are not preventable are: Family history and other genetic factors Age Genetic risk can interact with other factors for aneurysm. This means that smoking can be even more risky for some people than for others. One way to prevent an aneurysm forming is to take regular exercise, which also has wider health benefits. Intact brain aneurysms A brain aneurysm that has not yet burst can be treated if it is a high-risk one. Smaller aneurysms that present a lower risk will be left alone, because the risk of the brain surgery itself is not worth taking. Surgery to prevent the rupture of high-risk brain aneurysms is designed to prevent blood flowing into them. Two different operations are available: neurosurgical clipping and endovascular coiling: Clipping involves the surgeon finding the aneurysm in the brain and applying a small metal clip. The clip is usually placed directly across the bulging part of the artery. For coiling, the brain is reached with a catheter rather than through an opening in the skull. This is inserted at the groin or leg and travels up to the brain in an artery. Coils made of platinum are placed in the aneurysm to prevent blood from entering. Burst brain aneurysms If a brain aneurysm has burst, emergency treatment is needed. Patients are usually sent to a specialist neurology center. Emergency treatment of a subarachnoid hemorrhage because of burst brain aneurysm means:
