TIA and Stroke

Stroke and TIA are two kinds of "brain attacks"

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.

About TIAs

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.

  • A TIA lasts less than five minutes (a minute on average)
  • TIA is a proven risk factor for stroke, but it causes no permanent brain injury

About Strokes

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.

  • Strokes cause permanent injury to the brain
  • It is estimated that more than half of strokes can be prevented

Manage Risk Factors

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.

  • High blood pressure
  • High cholesterol
  • Cigarette smoking

Treatment and Prevention

TIA and stroke can be prevented.
In addition to managing your risk factors, there are medicines your doctor can prescribe to help prevent TIA and stroke.

  • Antiplatelets are drugs that interfere with clotting by preventing platelets (clotting cells in the blood) from sticking together
  • AGGRENOX is a combination of 2 antiplatelet drugs proven to help prevent recurrent TIA/stroke
