    Stroke Symptoms

    When discussing stroke symptoms, we often say “time is brain.” Every hour that a stroke is left untreated results in the loss of 120 million nerve cells and accelerates aging of the brain by 3.6 years. Recognizing the symptoms of stroke and seeking immediate medical attention can not only save lives but also prevent lasting neurological deficits for stroke victims.

    Think F.A.S.T. for Stroke Symptoms

    In other words, think F.A.S.T.

    fast stroke acronym illustration means watch out for facial drooping, arm weakness, speech difficulty and time to call 9-1-1

    Facial drooping – Ask the person to smile. Does one side of the face droop?
    Arm weakness – Ask the person to raise both arms. Does one arm drift downward?
    Speech difficulty – Ask the person to repeat a simple phrase, such as “the sky is blue.” Is their speech slurred or strange?
    Time – Call 9-1-1 immediately if you observe any of these signs, even if they go away. Note the time they began.


    TIA and Stroke Symptoms

    Sometimes stroke symptoms disappear within minutes. This may be a transient ischemic attack (TIA), which is also known as a “mini stroke.” Symptoms of a TIA resemble  the symptoms of a full-blown stroke but only last a few minutes because they are caused by a temporary blockage in the blood supply to brain.

    Although a TIA normally does not result in permanent disability, it may be a warning sign of a future stroke and an indication of a partially blocked or narrowed artery or a clot source in the heart. Even if stroke symptoms begin to disappear quickly, call 9-1-1.
