What is a stroke? It is a "brain attack", or damage to the brain from interruption of its blood supply.
Symptoms of a stroke include the following:
- muscular problems (difficulty walking, problems with coordination, weak/stiff muscles)
- visual problems (visual loss, double vision, blurred vision)
- sensory problems (numbness, reduced sensation in touch)
- speech problems (speech loss, slurred speech)
- lightheadedness, balance disorder, fatigue, inability to understand, mental confusion
There are two types of strokes; ischemic and hemorrhagic.
Ischemic occurs if an artery that supplies oxygen rich blood to the brain is blocked.
Hemorrhagic occurs if an artery in the brain leaks blood or ruptures. It can be caused by high blood pressure and aneurysms.
Strokes in the U.S.
Strokes are the fifth leading cause of death in the U.S. About 800,000 Americans die from strokes each year, with an average of stroke causing death every 4 minutes.
How to Prevent a Stroke
- Identify: review the risk factors and identify your personal risk
- Reduce risk factors: change lifestyle and take medication if necessary
- Recognize and respond: learn to notice signs and symptoms of a stroke
- Managing key risk factors, including high blood pressure, cigarette smoking, atrial fibrillation and physical inactivity
Treatments and Testing
A treatment option is an endovascular procedure* in which specially trained doctors try removing the blood clot by sending a catheter to the site of the blocked blood vessel in the brain.
For strokes caused by a bleed within the brain (hemorrhagic stroke), or by an abnormal tangle of blood vessels (AVM), surgical treatment may be done to stop the bleeding.

- About 80% of strokes are preventable
- Stroke is a brain attack
- There are nearly 7 million survivors who face a stroke
