Diabetics Suffer Greater Brain Damage From Stroke than non-Diabetics. If you are diabetic, there will be higher than normal amounts of LDL cholesterol - the 'bad' cholesterol - in your blood vessels. This can cause narrowing of the arteries in the brain (the cerebral arteries) which will reduce the blood flow and lead to high blood pressure, the number one risk factor for stroke. They are two main types of stroke you are likely to suffer. Ischemic stroke. Hemorrhagic stroke. Ischemic stroke can occur when fatty deposits or a blood clot become wedged in an artery in the brain, blocking the blood flow. A piece of plaque from a partial blockage, which may be in the jugular or one of the larger arteries, can break off and make its way to smaller cerebral arteries which then becomes blocked. When this happens, the part of the brain which depended on the blocked vessel no longer receives any blood. Without a blood supply there is no oxygen getting to that brain tissue, and it will start to die within minutes. The death of brain tissue will result in a stroke and the area of the body controlled by that part of the brain will then become paralyzed There are two types of stroke. The type caused by a burst artery,is known as hemorrhagic stroke, and the second type caused by blockage of an artery, is known as ischemic stroke. With hemorrhagic stroke, a cerebral aneurysm burst open and the leaked blood increases the pressure on the surrounding brain tissue. This causes the death of those cells. Blood supply to any areas that depend on the burst artery is also reduced and that area of the brain will die as well. After a stroke a healthy person's blood supply is usually restored by using alternative routes through nearby blood vessels. This can either be done surgically or it may happen naturally. However, for persons with this disease, these other routes may not available because the nearby blood vessels may be blocked or damaged as well. This means that as a general rule, the brain tissue of diabetics who suffer from stroke, will be without oxygen for a longer time and therefore suffer greater damage than that of a healthy person. An aneurysm is a bulge in a blood vessel resulting in a balloon like area filled with blood. If this occurs in the brain it is called a cerebral aneurysm. Having diabetes also increases the risk of stroke in younger people. Type two sufferers in their thirties and forties have an increased risk of stroke because of the buildup of cholesterol and other fats in the arteries, which was going on even before the disease was diagnosed.
