You can have a stroke without knowing it.

  • Your Answer:
  • Correct Answer:

“Silent strokes” are real. They’re caused when blood flow to a part of the brain is cut off.  But you may not notice anything out of the ordinary. Typically, you learn you’ve had one when permanent damage is found on a brain scan that you may have for some other reason.

“Silent strokes” and “warning strokes” are the same thing.

  • Your Answer:
  • Correct Answer:

A “warning stroke,” or transient ischemic attack (TIA), happens when a clot briefly keeps blood from getting to part of the brain. Unlike a true stroke, it doesn't cause permanent damage.

 

TIAs come and go fast, lasting about a minute on average. If you have a TIA, you’re more likely to have a full stroke in the months that follow.

If someone is showing signs of a stroke, you should:

  • Your Answer:
  • Correct Answer:

When your brain is starved for oxygen, every second counts. If your stroke is caused by a clot, you may be given a drug called tPA to break it up. This can save brain cells and prevent permanent damage. 

 

For the best chance of a full recovery, you must take tPA within 3 hours of the first signs of a stroke. Many people don't get to the hospital in time. Stroke remains the top cause of long-term disability in adults.  

If you’re angry a lot, you may be more likely to have a stroke.

If you’re angry a lot, you may be more likely to have a stroke.

  • Your Answer:
  • Correct Answer:

Having an angry personality can cause your blood vessels to narrow and your blood pressure to rise. People with short tempers have more thickening of the neck arteries, which boosts the odds of having a stroke.

 

If you have trouble controlling your anger, talk to your health care provider about how to handle it.

You can reverse the damage caused by a stroke.

You can reverse the damage caused by a stroke.

  • Your Answer:
  • Correct Answer:

Rehabilitation can help you learn to work around problems after a stroke, but you can’t repair the damage.  

 

Physical therapy helps build strength and coordination. Occupational therapy helps you take charge of life skills like eating and dressing. Speech-language therapy helps you improve communication.   

Bleeding in the brain causes most strokes.

Bleeding in the brain causes most strokes.

  • Your Answer:
  • Correct Answer:

Brain bleeds, which happen when a blood vessel bursts, make up only 13% of strokes. It's much more common for a clot to block a blood vessel that leads to the brain. This can happen when blood vessels narrow from fatty buildup along their walls.

Which of the following is NOT a sign of stroke?

Which of the following is NOT a sign of stroke?

  • Your Answer:
  • Correct Answer:

Signs of a stroke can include weakness on one side of the body and slurred speech. Chest pain may be a sign of a heart attack, which is also dangerous and needs medical attention right away.  

 

Stroke damage to the right side of your brain could cause weakness on the left side of your body.

Stroke damage to the right side of your brain could cause weakness on the left side of your body.

  • Your Answer:
  • Correct Answer:

 The right side of the brain controls the left side of the body, and vice versa. Any sudden changes that affect a single side of the body are red flags for stroke, including:

  • Numbness in an arm or leg
  • Drooping on one side of the face
  • Trouble seeing with one eye

 

Women who get certain types of migraines are more likely to have a stroke.

Women who get certain types of migraines are more likely to have a stroke.

  • Your Answer:
  • Correct Answer:

Strokes are more common in women who get migraines with visual signs called auras. But the risk is still low, and doctors say these women are less likely to have disabilities after a stroke than survivors with no history of migraines. They’re not sure why.

 

If you have frequent migraines with auras, your doctor may tell you to stop taking birth control pills, to reduce your chance of a stroke.

The signs of stroke depend on what part of the brain loses its blood supply.

The signs of stroke depend on what part of the brain loses its blood supply.

  • Your Answer:
  • Correct Answer:

When part of the brain stops receiving blood and oxygen, that part can no longer do its job. If it's an area linked to language, you may have trouble speaking. If it's an area that controls muscles, you may not be able to move an arm or a leg.
