The top preventable risk factor for stroke is smoking. Research also has shown African-Americans are at higher risk of stroke than Caucasians. A family history of stroke, or a personal history of stroke or heart attack, also increase the risk of stroke. Strokes are more common in men, but more women die from them. However, the older a person is, the higher their risk of stroke. Strokes can happen to a person of any age, including children. Each of these conditions affects the flow of blood through the heart and blood vessels and increases the risk of stroke. Low blood pressure can result from a heart attack, large loss of blood or severe infection. This usually occurs with narrowed or diseased arteries. Ischemic strokes occur when blood supply is cut off to part of the brain by a blood clot or narrowing of the arteries.īlood clots may be caused by an irregular heartbeat such as arrhythmia, problems with the heart valve, infection of the heart muscle, hardening of the arteries, blood-clotting disorders, inflammation of the blood vessels, or a heart attack.Ī less common cause of ischemic stroke occurs when blood pressure becomes too low (hypotension), reducing blood flow to the brain. This is known to be one of the early warning signs of a stroke. Some patients experience symptoms that clear up within only a few minutes, which may be a sign of a transient ischemic attack (TIA). Not all symptoms occur with every stroke, and sometimes they go away and return. The effects of an acute ischemic stroke may cause additional symptoms in women including: Sudden, severe headache with no known cause.Sudden dizziness, loss of balance or coordination.Sudden trouble seeing in one or both eyes.Sudden numbness or weakness of the face, arm or leg, especially on one side of the body.If you notice one or more of these signs in another person or in yourself, do not wait to seek help.
