Stroke

Symptoms

Stroke symptoms vary considerably, depending upon:

  • The type of stroke
  • The part of the brain that is affected
  • The severity of the brain damage

Primary Symptoms

Usually, symptoms start suddenly and a disability is evident right away—for instance, weakness or paralysis in some part of the body, with or without a headache. Often, the symptoms get progressively worse over the first hours or days, or the symptoms may come and go. Some people are not even aware they have had a stroke. In cases of TIA, symptoms may last only a few minutes and go away completely.

Go to the hospital immediately if you suspect that you are having a stroke or TIA. Call 911 right away or have someone drive you. If it is a TIA, the symptoms will likely disappear before you get to the hospital. However, you still need to be evaluated. 

The National Stroke Association suggests following the “FAST” guideline below if you suspect that you or someone in your care may be having a stroke.

FACE:  Ask the person to smile. Does one side of the face droop?
ARMS:  Ask the person to raise both arms. Does one arm drift downward?
SPEECH: Ask the person to repeat a simple sentence. Does the speech sound slurred or strange?
TIME:  If you observe any of these signs, it’s time to call 911 or go to the nearest stroke center or hospital. 

Other Symptoms

  • Sleepiness, reduced responsiveness, unconsciousness, or coma
  • Changes in sense of touch, and sensations of pressure, temperature, or pain
