Sudden unexplained dizziness, instability or falling. A sudden severe and unexplained headache. If you are experiencing any of these symptoms, seek medical help immediately at the nearest emergency room. Beyond about three hours, this kind of treatment becomes less effective, and may even be harmful. By waiting to go to the emergency room, a person whose stroke may otherwise have been treatable risks permanent effects, such as losing the ability to walk, speak or use one or more limbs.
Some people are at higher risk of stroke than others.
Your risk is elevated if you are over 55 or have a family history of stroke. Also, African-Americans are three times more likely than the general population to have a stroke. High blood pressure, smoking, hardening of the arteries, high cholesterol, an abnormal heart rate or diabetes can also add to the risk. As with heart disease, your lifestyle choices can play a big role in preventing stroke. A low-fat, high fiber diet, regular exercise and a general reduction in stress all can help reduce the risk of stroke.
