Stroke: Don't Ignore These Warning Signs

  • An Attack on Your Brain
    An Attack on Your Brain
    Strokes are sometimes referred to as "brain attacks." The most common type of stroke happens when an embolus (an obstruction like a blood clot or fragmented cholesterol plaque) prevents fresh, oxygenated blood from getting to the brain. Nearby brain cells are denied oxygen and nutrients, so they begin to die.

    No. 1 Cause of Disability
    Stroke is the number three killer in the United States, and it causes more serious long-term disabilities than any other disease. Because a stroke damages the brain, it's possible a person won't realize that he or she is having a stroke. So it could be imperative that someone else quickly recognizes the symptoms and calls 911. Do you know which warning signs to look for?

    Call 911
    When someone is having a stroke, every minute counts. Ischemic stroke is the most common type, and it can be treated with aggressive clot-busting drug therapy. However, effective stroke treatment must begin within three hours of the stroke. So you should get to the hospital within 60 minutes in order to have time for testing and treatment. If you suspect someone is having a stroke, don't wait for the symptoms to get better or worse. Call 911 immediately.
