A stroke injures the brain the same way a heart attack injures the heart, by cutting off blood and oxygen to affected tissues. This is why a stroke is sometimes called a brain attack.
Both stroke and TIA share the same symptoms. But while a stroke may cause permanent injury and disability, TIAs last only a few minutes and leave no lasting effects. If you have had a TIA or stroke, you should know that aggressive treatment can help prevent a recurrence.

to learn more about TIA and stroke.
A TIA is a "mini-stroke."
A transient ischemic attack, or TIA, is caused by a brief blockage in a blood vessel that prevents part of the brain from getting the blood (and oxygen) it needs.
Stroke is a leading cause of disability.
A stroke is caused when a blood clot blocks a blood vessel (ischemic stroke), or when a blood vessel breaks (hemorrhagic stroke). This stops blood (and oxygen) from reaching part of the brain. Within minutes brain cells begin to die. And the functions these cells control are lost.
Ask your doctor about your risk factors.
There are a number of risk factors that are common to stroke and TIA. Some of them, like age, race, and heredity, are beyond your control. But some of the most important ones can be managed or treated with the help of your doctor.
