Transient Ischemic Attack (TIA)

A transient ischemic attack (TIA) is a stroke that lasts only a few minutes. It happens when the blood supply to part of the brain is briefly blocked. Symptoms of a TIA are like other stroke symptoms, but do not last as long. They happen suddenly, and include: - Numbness or weakness, especially on one side of the body - Confusion or trouble speaking or understanding speech - Trouble seeing in one or both eyes - Difficulty walking - Dizziness - Loss of balance or coordination Most symptoms of a TIA disappear within an hour, although they may last for up to 24 hours. Because you cannot tell if these symptoms are from TIA or a stroke, you should go to the hospital right away. TIAs are often a warning sign for future strokes. Taking medicine, such as blood thinners, may reduce your risk of a stroke. Your doctor might also recommend surgery. You can also help lower your risk by having a healthy lifestyle. This includes not smoking, not drinking too much, eating a healthy diet and exercising. It is also important to control other health problems, such as high blood pressure and cholesterol.
