Transient Ischemic Attack
WHAT YOU NEED TO KNOW:
A transient ischemic attack (TIA), or mini-stroke, happens when blood cannot flow to part of the brain. A TIA only lasts minutes to hours and does not cause lasting damage. It is still important to get immediate medical care. A TIA may be a warning that you are about to have an ischemic stroke. An ischemic stroke happens when blood flow to the brain is suddenly blocked, usually by a blood clot.
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
Call your doctor or neurologist if:
- You have double vision or vision loss.
- You have a severe headache or feel dizzy.
- Your blood pressure or blood sugar level is higher or lower than you were told it should be.
- You have questions or concerns about your condition or care.
Warning signs of a stroke:
The word F.A.S.T. can help you remember and recognize warning 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.
You may need any of the following:
- Antiplatelets prevent blood clots from forming. Aspirin is an antiplatelet. 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 needed to treat diabetes, depression, high cholesterol, or blood pressure problems. You may also need medicine to decrease the pressure in your brain, reduce pain, or prevent seizures.
- Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him of her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.
Follow up with your doctor or neurologist in 1 to 2 days:
Write down your questions so you remember to ask them during your visits.
What you can do to prevent another TIA or a 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 your blood pressure.
- 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 ways to relax, such as deep breathing or listening to music.
