A transient ischemic attack is when blood flow to a part of the brain stops for a brief period of time. Dr. Edward Hill explains more about TIAs in todays 60 Second Housecall.

Dr. Hill:

A transient ischemic attack, or TIA, happens when a blood vessel called an artery becomes blocked. This causes less blood to get to your brain. It is sometimes called a mini stroke.

The difference between TIA and stroke is that in TIA, the artery doesnt stay blocked and the blood starts to flow again. In a stroke, the artery stays blocked and parts of the brain die.

The symptoms of TIA come on suddenly and go away on their own. Common symptoms include weakness on one side of your body, problems speaking or walking, and blindness in one eye.

Anyone can have a TIA, but some people have risk factors that make it more likely. Risk factors include diabetes, high blood pressure, high cholesterol, obesity and smoking.

If you are having symptoms of a TIA, you should get medical attention right away. It is important to find out whether you are having a TIA or a stroke because the symptoms are the same.
