Diabetes increases the severity of atherosclerosis - narrowing of the arteries due to accumulation of fatty deposits - and the speed with which it develops. PAD causes the blood vessels that carry blood to the arms and legs to become clogged. In this condition, the blood vessels in the neck that lead to the brain become clogged. This includes heart failure, a heart defect, a heart infection or a heart rhythm that isn't typical. If you can't control your cholesterol through dietary changes alone, your provider may prescribe a statin or another type of cholesterol-lowering medication. Eating less cholesterol and fat, especially saturated fat and trans fat, may reduce the plaques in your arteries. Your health care provider will help you decide on a target blood pressure based on your age, whether you have diabetes and other factors. The risk of a stroke begins to increase at blood pressure readings higher than 140/90 millimeters of mercury (mm Hg). Having one or more of these risk factors doesn't mean you'll have a stroke, but your risk increases if you have two or more of them. You can control or treat a number of factors - including certain health conditions and lifestyle choices - that increase your risk of a stroke. However, with proper treatment of sickle cell disease, you can lower your risk of a stroke.

Sickle-shaped blood cells carry less oxygen and also tend to get stuck in artery walls, hampering blood flow to the brain. Another name for this inherited disorder is sickle cell anemia. Stroke is a frequent complication of sickle cell disease. If you've had one or more TIAs, you're much more likely to have a stroke. But as women age, their risk of a stroke goes up. Men have a slightly higher risk of a TIA and a stroke. Your risk increases as you get older, especially after age 55. Your risk may be greater if one of your family members has had a TIA or a stroke. But knowing you're at risk can motivate you to change your lifestyle to reduce other risks. You can't change the following risk factors for a TIA and stroke. Some risk factors for a TIA and stroke can't be changed. A blood clot moving to an artery that supplies the brain from another part of the body, most commonly from the heart, also may cause a TIA. Plaques can decrease the blood flow through an artery or lead to the development of a clot. The underlying cause of a TIA often is a buildup of cholesterol-containing fatty deposits called plaques (atherosclerosis) in an artery or one of its branches that supplies oxygen and nutrients to the brain. In a TIA, unlike a stroke, the blockage is brief, and there is no permanent damage. In an ischemic stroke, a clot blocks the blood supply to part of the brain. A TIA has the same origins as that of an ischemic stroke, the most common type of stroke.
