Stroke: How to Recognize It and What to Do About It

What is a stroke?

A stroke is like a “brain attack.” In a heart attack, not enough blood gets to the heart muscle. In a stroke, not enough blood gets to the brain. Parts of the brain can die if blood is cut off for more than a couple of hours. Weakness, numbness, or speech problems may clear up within a few hours if blood is cut off for a shorter time. This is called a transient ischemic attack (TIA) rather than a stroke.

How can I tell if someone has a stroke?

There are several ways to tell if someone has a stroke. F.A.S.T. is one way to remember the signs of stroke. If you see a person with any of these signs, call 9-1-1 for help right away:

  • Face drooping. Does one side of the face droop or is it numb? Ask the person to smile. Is the person's smile uneven?

  • Arm weakness. Is one arm weak or numb? Ask the person to raise both arms. Does one arm drift downward?

  • Speech problems. Is speech slurred? Is the person unable to speak or hard to understand? Ask the person to repeat a simple sentence, like “The sky is blue.” Is the sentence repeated correctly?

  • Time to call 9-1-1. If someone shows any of these symptoms, even if they go away, call 9-1-1 and get the person to the hospital right away. Check the time so you will know when the first symptoms appeared.

Five “suddens” also cover stroke warning signs:

  • Sudden numbness or weakness of face, arm, or leg, especially on one side of the body

  • Sudden confusion, trouble speaking or understanding

  • Sudden trouble seeing in one or both eyes

  • Sudden trouble walking, dizziness, loss of balance or coordination

  • Sudden severe headache with no known cause

If you think you or a family member may be having a stroke, call 9-1-1. Acting quickly improves the chance of survival and recovery. The doctor will do an exam and may order other tests, including pictures of the brain.

How can I prevent stroke and TIA?

  • If you smoke, quit.

  • Work with your doctor to control high blood pressure, high cholesterol, heart disease, and diabetes.

  • Walk or do some other exercise most days of the week.

  • Eat more fruits, vegetables, and fish.

  • Skip sugary drinks.
