How to Tell If Someone is Having a Stroke

Posted on May 26, 2011 | 2 comments

Stroke is the third leading cause of death and it is the leading cause of adult disability in the United States. What makes it particularly scary is that it can occur suddenly and in such a way that the person having the stroke may be unaware that there is anything seriously wrong.

There are treatments that can halt or reverse the damage caused by an acute stroke, but they only work if they are administered in the short time window after symptoms first appear. To help a possible stroke victim, remember the word FAST: face, arms, speech and time.

  • Face: Does one side of the person’s face drop when you ask him or her to smile?
  • Arms: Ask the person to raise both arms. Does one arm drift downward?
  • Speech: Have the person try to repeat a simple sentence. Are the words slurred or incorrect?
  • Time: If you suspect that someone has had a stroke, call 911 to get the person to the emergency room right away where a team of specialists can evaluate him or her. The time you save may greatly improve the outcome of the stroke.

  1. Hello Dr,

    What is difference between stroke & veritigo? How to determine person having stroke or veritgo?


    • Dear Balaji,

      Vertigo in older patients is usually benign though very uncomfortable. Infrequently, however, it can be caused by stroke. When caused by stroke there are often other associated problems like face numbness or weakness, double vision, clumsiness or impaired function of arms or legs. The only way to be certain is to be seen and examined by a physician. Emergency Department physicians have neurologists on call to help them, and MRI imaging can usually provide a definite answer.
