Transient ischemic attack

Common Name(s)

Transient ischemic attack

A stroke occurs when the blood flow to the brain is interrupted or cut-off. When this happens, the affected area of the brain does not receive the oxygen and nutrients that it needs. A transient ischemic attack (TIA) is sometimes referred to as a “mini-stroke” or a “warning stroke”. Like a stroke, a TIA is caused by the formation of a blood clot that interrupts or cuts off blood flow to the brain. The difference between a TIA and a stroke is that in a TIA, the interruption in blood flow is only temporary and there is usually no permanent injury to the brain. A TIA lasts about a minute on average, and usually no longer than five minutes.

The symptoms of a TIA can include sudden onset of weakness, numbness, or paralysis in a body part, slurred speech, blurred vision, loss of vision, and loss of coordination. The most common cause of a TIA is the buildup of cholesterol in the arteries, which causes a small blood clot. TIA’s are called “warning strokes” because one in three people who experience a TIA will later experience a stroke. If you believe that you are having a TIA, you should seek medical help immediately. If you have had a TIA, there are steps that you can take to lower your risk of stroke. These steps include: working to lower cholesterol levels, quitting smoking, engaging in regular physical activity, improving nutrition, limiting alcohol intake, and stopping any illicit drug use.
