WHAT YOU NEED TO KNOW:
What is an ischemic stroke?
An ischemic stroke occurs when blood flow to part of your brain is blocked. The block is usually caused by a blood clot that gets stuck in a narrow blood vessel. When oxygen cannot get to an area of the brain, tissue in that area may get damaged. The damage can cause loss of body functions controlled by that area of the brain.
What are the warning signs of a stroke?
The word F.A.S.T. can help you remember and recognize signs of a stroke.
- F = Face: One side of the face droops.
- A = Arms: One arm starts to drop when both arms are raised.
- S = Speech: Speech is slurred or sounds different than usual.
- T = Time: A person who is having a stroke needs to be seen immediately. A stroke is a medical emergency that needs immediate treatment. Some medicines and treatments work best if given within a few hours of a stroke. Early treatment can decrease the risk of long-term effects of a stroke.
What are the signs and symptoms of an ischemic stroke?
Signs and symptoms may begin suddenly and worsen quickly. Any of the following may appear minutes or hours after a stroke:
- Severe headache
- Blurred or double vision, or vision loss
- Numbness, tingling, weakness, or paralysis on one side of your body
- Trouble walking or speaking
- Dizziness, confusion, or fainting
What increases my risk for an ischemic stroke?
- Age 55 or older
- A family history of stroke, or a personal history of transient ischemic attack (TIA)
- Obesity or not enough physical activity
- High cholesterol, high blood pressure, or diabetes
- Smoking cigarettes or using illegal drugs
- A heart condition, such as atrial fibrillation, a recent heart attack, or valve disease
- A blood clotting disorder, such as Factor V Leiden
- In women, oral birth control pills or hormone replacement therapy
How is an ischemic stroke diagnosed?
Your healthcare provider will examine you and ask about your symptoms. He or she will ask if you have any medical conditions. You may need any of the following:
- Blood tests may be used to check your overall health. Your blood's ability to clot will also be tested. Blood tests may include a check for diabetes. Diabetes increases your risk for a stroke.
- CT or MRI pictures may show where the stroke happened and any damage to your brain. You may be given contrast liquid to help your skull and brain show up better in the pictures. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body.
- An arteriography is used to take x-rays of your arteries to look for blood flow blockage.
How is an ischemic stroke treated?
Your healthcare provider will talk to you and your family about ways to treat an ischemic stroke. They will explain the risks and benefits of each treatment. You will be able to help create a treatment plan that may include any of the following:
- Medicines may be used to help break apart clots, or prevent clots from forming. Other medicines may be given to treat health conditions that increase the risk for a stroke. Examples are high cholesterol, high blood pressure, and diabetes.
- Surgery may be needed to remove the clot. You may also need surgery to widen arteries or to place a filter into a blood vessel. Surgery can help improve blood flow and prevent clots.
What can I do to manage an ischemic stroke?
- Go to stroke rehabilitation (rehab) if directed. Rehab is a program run by specialists who will help you recover abilities you may have lost. Specialists include physical, occupational, and speech therapists. Physical therapists help you gain strength or keep your balance. Occupational therapists teach you new ways to do daily activities, such as getting dressed. Your therapy may include movements for everyday activities. An example is being able to raise yourself from a chair. A speech therapist helps you improve your ability to talk and swallow.
- Wear pressure stockings as directed. Pressure stockings help keep blood from pooling in your leg veins. Your healthcare provider can prescribe stockings that are right for you. Do not buy over-the-counter pressure stockings unless your healthcare provider says it is okay. They may not fit correctly or may have elastic that cuts off your circulation. Ask your healthcare provider when to start wearing pressure stockings and how long to wear them each day.
- Make your home safe. Remove anything you might trip over. Tape electrical cords down. Keep paths clear throughout your home. Make sure your home is well lit. Put nonslip materials on surfaces that might be slippery. An example is your bathtub or shower floor. A cane or walker may help you keep your balance as you walk.
What can I do to prevent another stroke?
- Manage health conditions. A condition such as diabetes can increase your risk for a stroke. Control your blood sugar level if you have hyperglycemia or diabetes. Take your prescribed medicines and check your blood sugar level as directed.
- Check your blood pressure as directed. High blood pressure can increase your risk for a stroke. If you have high blood pressure, follow your healthcare provider's directions for controlling it.
- Do not use nicotine products or illegal drugs. Nicotine and other chemicals in cigarettes and cigars can cause blood vessel damage. Nicotine and illegal drugs both increase your risk for a stroke. Ask your healthcare provider for information if you currently smoke or use drugs and need help to quit. E- cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.
- Talk to your healthcare provider about alcohol. Alcohol can raise your blood pressure. The recommended limit is 2 drinks in a day for men and 1 drink in a day for women. Do not binge drink or save a week's worth of alcohol to drink in 1 or 2 days. Limit weekly amounts as directed by your provider.
- Eat a variety of healthy foods. Healthy foods include whole-grain breads, low-fat dairy products, beans, lean meats, and fish. Eat at least 5 servings of fruits and vegetables each day. Choose foods that are low in fat, cholesterol, salt, and sugar. Eat foods that are high in potassium, such as potatoes and bananas. A dietitian can help you create healthy meal plans.
- Maintain a healthy weight. Ask your healthcare provider how much you should weigh. Ask him or her to help you create a weight loss plan if you are overweight. He or she can help you create small goals if you have a lot of weight to lose.
- Exercise as directed. Exercise can lower your blood pressure, cholesterol, weight, and blood sugar levels. Healthcare providers will help you create exercise goals. They can also help you make a plan to reach your goals. For example, you can break exercise into 10 minute periods, 3 times in the day. Find an exercise that you enjoy. This will make it easier for you to reach your exercise goals.
- Manage stress. Stress can raise your blood pressure. Find new ways to relax, such as deep breathing or listening to music.
- Talk to your healthcare provider about risk factors for women. Birth control pills increase your risk, especially if you are older than 35 or smoke cigarettes. Talk to your healthcare provider about other forms of contraception. Estrogen levels drop during menopause. Low estrogen levels may increase your risk for stroke. Talk to your healthcare provider about hormone replacement therapy to reduce your risk for a stroke.
What do I need to know about depression after a stroke?
Talk to your healthcare provider if you have depression that continues or is getting worse. Your provider may be able to help treat your depression. Your provider can also recommend support groups for you to join. A support group is a place to talk with others who have had a stroke. It may also help to talk to friends and family members about how you are feeling. Tell your family and friends to let your healthcare provider know if they see any signs of depression:
- Extreme sadness
- Avoiding social interaction with family or friends
- A lack of interest in things you once enjoyed
- Trouble sleeping
- Low energy levels
- A change in eating habits or sudden weight gain or loss
