An ischemic stroke
occurs when blood flow to a part of your brain is blocked. The blockage 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.
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.
Common symptoms include the following:
Signs and symptoms may begin suddenly and worsen quickly. Any of the following may appear minutes or hours after a stroke, and worsen quickly:
- 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
Call your local emergency number (911 in the US) or have someone else call if:
- You have any of the following signs of a stroke:
- Numbness or drooping on one side of your face
- Weakness in an arm or leg
- Confusion or difficulty speaking
- Dizziness, a severe headache, or vision loss
- You have a seizure.
- You feel lightheaded, short of breath, and have chest pain.
- You cough up blood.
- You have a severe headache, or loss of balance or coordination.
Call your doctor if:
- Your arm or leg feels warm, tender, and painful. It may look swollen and red.
- You have double vision or vision loss.
- You have unusual or heavy bleeding.
- Your blood pressure is higher or lower than you were told it should be.
- You have questions or concerns about your condition or care.
- Thrombolytics help break apart clots.
- Antiplatelets , such as aspirin, help prevent blood clots. Take your antiplatelet medicine exactly as directed. These medicines make it more likely for you to bleed or bruise. If you are told to take aspirin, do not take acetaminophen or ibuprofen instead.
- Blood thinners help prevent blood clots. Examples of blood thinners include heparin and warfarin. Clots can cause strokes, heart attacks, and death. The following are general safety guidelines to follow while you are taking a blood thinner:
- Watch for bleeding and bruising while you take blood thinners. Watch for bleeding from your gums or nose. Watch for blood in your urine and bowel movements. Use a soft washcloth on your skin, and a soft toothbrush to brush your teeth. This can keep your skin and gums from bleeding. If you shave, use an electric shaver. Do not play contact sports.
- Tell your dentist and other healthcare providers that you take anticoagulants. Wear a bracelet or necklace that says you take this medicine.
- Do not start or stop any medicines unless your healthcare provider tells you to. Many medicines cannot be used with blood thinners.
- Tell your healthcare provider right away if you forget to take the medicine, or if you take too much.
- Warfarin is a blood thinner that you may need to take. The following are things you should be aware of if you take warfarin:
- Foods and medicines can affect the amount of warfarin in your blood. Do not make major changes to your diet while you take warfarin. Warfarin works best when you eat about the same amount of vitamin K every day. Vitamin K is found in green leafy vegetables and certain other foods. Ask for more information about what to eat when you are taking warfarin.
- You will need to see your healthcare provider for follow-up visits when you are on warfarin. You will need regular blood tests. These tests are used to decide how much medicine you need.
- Other medicines may be given to treat other health conditions such as high cholesterol, high blood pressure, or 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. This surgery helps to improve blood flow and prevent clots.
Your healthcare provider will assess (test) your recovery 90 days (3 months) after your stroke. This may be done over the phone or in person. Your provider will ask how well you can do the activities you did before the stroke. He or she will also ask how well you can do your daily activities without help. Your provider may make recommendations for you based on your test. For example, you may need someone to help you walk safely. You may also need help with daily activities, such as getting dressed. Based on your answers, your provider may do this test again over time.
- Go to rehabilitation (rehab) as directed. Rehab is an important part of treatment. A speech therapist helps you relearn or improve your ability to talk and swallow. You may start slowly and start doing more difficult tasks over time. Physical therapists can help you gain strength and build endurance. Occupational therapists teach you new ways to do daily activities, such as getting dressed. Therapy can help you improve your ability to walk or keep your balance. Your therapy may include tasks or movements you will need to do for everyday activities. An example is being able to raise or lower yourself from a chair.
- 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.
- Use walking devices as directed. A cane or walker may help you keep your balance as you walk.
What you need to know about depression:
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
Decrease your risk for another stroke:
- Manage health conditions. Take your medicine as directed. Check your blood pressure and blood sugar levels as directed. Keep a record and bring it to your follow-up visits.
- Eat a variety of healthy foods. Healthy foods include whole-grain breads, low-fat dairy products, beans, fish, and lean meats. Eat at least 5 servings of fruits and vegetables each day. Choose foods that are low in salt, unhealthy fats (saturated and trans fat), salt, and sugar. Eat foods that are high in potassium, such as potatoes and bananas. Ask your dietitian what other nutrition guidelines you should follow. He or she can help you choose foods that are right for you.
- 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. Ask about the best exercise plan for you.
- Do not drink alcohol. Alcohol can increase your risk for a stroke. Alcohol may also increase your blood pressure or thin your blood. Blood thinning can increase your risk for hemorrhagic stroke.
- Do not smoke cigarettes or use illegal drugs. Smoking and drugs increase your risk for a stroke. Nicotine and other chemicals in cigarettes and cigars can also cause lung damage. 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.
Follow up with your healthcare provider or neurologist as directed:
You may need to come in for regular tests of your brain function. You may also need regular blood tests. Write down your questions so you remember to ask them during your visits.
