Keys to Recognizing a Stroke


WebMD Feature

Strokes can happen to anyone at any time, regardless of sex or age. Each year, nearly 800,000 people in the U.S. have a stroke, and 130,000 die from one. Of those who survive, more than two-thirds will have some disability. Recognizing stroke symptoms is key to preventing a needless death.

“Many patients who have a stroke develop droopiness on one side of the face. And they get weakness in the arm, so in many cases their arm falls to the side and they can’t lift it. If you ask them to smile, it’s not symmetrical,” says Holli A. DeVon, PhD, RN, an associate professor in the College of Nursing at the University of Illinois at Chicago.

In general, the best way to tell if someone is having a stroke is to use the acronym FAST, which stands for face drooping, arm weakness, speech difficulty, and time to call 911.

If you think someone is having a stroke, ask them to smile, raise an arm, and speak a short sentence. If you see any of these signs, it's time to call 911.

Other common stroke symptoms can include the sudden onset of:

  • Numbness of the face, arm, or leg
  • Confusion, trouble speaking or understanding
  • Vision trouble in one or both eyes
  • Trouble walking, dizziness, loss of balance or coordination
  • Severe headache with no known cause

When It Isn't Obvious

Knowing when a stroke has occurred can be tricky. The classic image of stroke is not being able to move on one side, or to speak. But because some strokes are less severe than others, you might feel only minor weakness in an arm or leg if you’ve had one.

There are two types of stroke; the symptoms are the same:

As you age, the risk for a mini-stroke -- known as a transient ischemic attack, or TIA -- rises. The symptoms of TIA mimic those of an actual stroke but go away within about 24 hours.

The likelihood that a full ischemic stroke will follow a TIA is strong -- up to 40 percent of people who have a TIA go on to have a stroke. And it doesn’t take long -- 5% of people who have TIA have a stroke within 2-3 days; 10% to 15% have one within 3 months.
