Aneurysm and Stroke

Definition: a ballooning out or dilation in an artery – when this occurs in the central nervous system and then bursts, causing bleeding, it is known as a stroke. Not all strokes are caused by aneurismal bleeding, however; some are caused by blood clots, which interrupt blood supply to the brain. A transient ischemic attack (TIA) is decreased blood supply to the brain temporarily.

Causes: an aneurysm occurs when the wall of an artery is weakened, such as from atherosclerosis or other disease processes. Abdominal aortic aneurysms are the most common aneurysms. In a stroke, the person usually has a history of high blood pressure, diabetes, heart valve disease, or atherosclerosis (hardening of the arteries).

Signs and symptoms:

An aneurysm may have no signs or symptoms until late. In a stroke, there are definite neurological signs, such as loss of consciousness, weakness, numbness, inability to move and arm or leg (inability to raise both arms above the head is a good sign), slurring of the speech, seizures, sudden headache, loss or blurring of vision or comprehension, and difficulty swallowing.

Treatment:

Medically, until the aneurysm is so bad that it requires surgery for bypass or stent or other procedure, includes exercise, weight loss, and smoking cessation. A person may also be prescribed medication to help prevent blood clots. A stroke is a medical emergency, as is a transient ischemic attack. A person may be prescribed aspirin or anti-coagulant drugs.

Alternative management of aneurysms and strokes involves supplements that strengthen the walls of the arteries. These include vitamins A and C, and flavanoids such as quercetin, hesperidin, rutin, and citrus bioflavanoids. Supplementation with fish oils can be beneficial. Anti-oxidants are helpful.

Prevention involves a diet rich in fruits and vegetables, which has been shown to lower the risk of strokes. Exercise and maintaining a normal weight have been shown to be essential. Reduction of salt intake and controlling high blood pressure, along with controlling diabetes will help prevent strokes and aneurysms. Smoking cessation also will help prevent both strokes and aneurysms.
