What is a Stroke?

   A stroke occurs when a blood vessel (artery) that supplies blood to the brain bursts or is blocked by a blood clot. Within minutes, the nerve cells in that area of the brain are damaged and may die within a few hours. As a result, the part of the body controlled by the damaged section of the brain cannot function properly.

If you have symptoms of a stroke, you need emergency care just as if you are having a heart attack. If medical treatment begins soon after symptoms are noticed, fewer brain cells may be permanently damaged.

What are the Symptoms?

    Symptoms of a stroke begin suddenly and may include:

  • Sudden numbness, weakness or paralysis of the face, arm or leg, especially on one side of the body.
  • Sudden vision problems in one or both eyes, such as double vision or loss of eyesight.
  • Sudden confusion, such as trouble speaking or understanding.
  • Sudden trouble walking, dizziness, loss of balance or coordination.
  • Sudden severe headache with no known cause.


  • Call 9-1-1 immediately if you experience symptoms!

    What is the Treatment?

        Ischemic stroke: Doctors will first stabilize your condition and try to restore or improve blood flow to the brain. If less than three hours have passed since symptoms began, tissue plasminogen activator (t-PA), a clot-dissolving medication, may be administered. Research shows that the medication can improve recovery from a stroke, particularly if given within 90 minutes of your first symptoms.

    Hemorrhagic stroke: Treatment for a hemorrhagic stroke is difficult. It includes monitoring and controlling bleeding and pressure in the brain and other efforts to stabilize vital signs, such as blood pressure.

    After your initial emergency treatment, health professionals will focus on preventing complications such as pneumonia and future strokes. Your health professional will also involve you in a stroke rehabilitation program as soon as possible.

    Another treatment for stroke, carotid artery stenting, can sometimes be used to open narrowed arteries to the brain in an effort to prevent stroke. Carotid artery stenting, also called cerebral percutaneous transluminal angioplasty, is similar to cardiac angioplasty, the procedure used to open narrowed arteries that supply blood to the heart. During this procedure, a vascular surgeon inserts a metal tube called a stent inside your carotid artery to increase blood flow in areas blocked by plaque.
