Before we begin: Transient ischemic attack (TIA) is a mini stroke. Even though the symptoms come and go, learn why TIA needs medical attention right away.
This tutorial walks you through everything you need to know about transient ischemic attack. We explain it in plain language, step by step, so whether you are a student, a patient, or simply curious, you will come away with a solid understanding.
We cover what it is, why it matters, how it is diagnosed, and what you can do about it. Key facts are called out along the way.
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 a 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.
