What is Transient Ischemic Attack (TIA) Causes Symptoms & Risk Factors
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. The Symptoms are like other strokes, 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
- 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 can’t tell if these symptoms are from a TIA or a stroke, you should go to the emergency room 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.
What Are The Symptoms of TIA?
When someone’s having a TIA, it looks like a stroke. The big difference is that TIAs last just a few minutes and the symptoms usually go away in an hour.
If you see or have one or more of these symptoms, don’t wait, go to your local emergency room.
- Sudden numbness or weakness of ace, arm, or leg, especially on one side of the body.
- Confusion or trouble speaking or understanding speech.
- Trouble seeing in one or both eyes.
- Sudden trouble walking, dizziness, or loss of balance or coordination
- Sudden severe headache with no known cause.
What Causes a TIA?
TIAs typically happen because a blood clot gets lodged in an artery that supplies blood to the brain. Without regular blood flow, your brain is starved for oxygen and can’t work like it normally does.
That’s why you get symptoms like muscle weakness or slurred speech. It would be like having a clogged fuel line in your car. Your engine can’t run if it’s not getting gas.
