Signs of Stroke
When it comes to a stroke, time lost can be brain lost. Which is why knowing the signs of stroke and reacting quickly can save lives.
What Are the Signs of Stroke?
When trying to identify the signs of a stroke, think B.E.F.A.S.T.:
- Balance- Is the person experiencing Sudden dizziness, loss of balance or coordination?
- Eyes- Is the person having sudden trouble seeing out of one or both eyes?
- 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 difficulty - 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 the symptoms go away, call 9-1-1 and get the person to the hospital immediately. Check the time so you'll know when the first symptoms appeared.
Even if you notice only one symptom, immediately call 911.
B.E.F.A.S.T. was created by the American Stroke Association.

How Strokes Affect the Body
Since each area of your brain controls different body functions, the effect a stroke has on your body depends on the location of the obstruction and the extent of brain tissue affected.
While every stroke patient is different, there are physical, behavioral, communication and swallowing disorders that many people share.

Communication and Swallowing Conditions:
- Aphasia - loss of ability to understand or express speech

- Dysarthia - difficulty articulating speech
- Dysphagia - difficulty swallowing
