Stroke (Completed)

You have had a stroke, or cerebrovascular accident (CVA). This is caused by a loss of blood flow to part of your brain. Ischemic type strokes can occur when a blood clot forms inside the carotid artery (main artery from the heart to the brain) or inside the heart and travels to the brain to lodge in a blood vessel and block blood flow. Another common ischemic cause of stroke is a gradual narrowing of the arteries in the brain because of buildup of fatty deposits (plaque). A clot can form at such a narrowing. Less commonly, infection or cancer can cause ischemic stroke. An autoimmune disease can cause inflammation of the blood vessels and also lead to stroke. A second type of stroke is hemorrhagic stroke. It occurs when a blood vessel ruptures and stops the flow of blood to part of the brain.


Blocked blood flow in different areas of the brain can cause different symptoms. If you have had a stroke before, a new one may be different. A memory aid for the basic signs of a stroke is F.A.S.T.


  • F: Face drooping, or numbness on one side. This may be more noticeable when you ask the affected person to smile.

  • A: Arm weakness or numbness. The affected person may have trouble using or lifting one side.

  • S: Speech difficulty. Speech may be slurred or hard to understand. The affected person may also use the wrong words.

  • T: Time to call 911. Time is critical in treating a stroke. Call 911 as soon as you suspect a stroke has happened—even a small one. The sooner treatment is started the better, even if the symptoms go away.

Other common symptoms of a stroke include:

  • Having trouble getting the right words to come out

  • Weakness in one leg

  • Numbness on one side

  • Trouble walking

  • Trouble with coordination

  • Trouble with vision

  • Severe headache

  • Confusion

  • Dizziness


After you have had a stroke, you are at risk of having another. Be sure to follow up with your healthcare provider for more assessment and treatment. If problems are found, your healthcare provider will advise treatment with medicines, procedures, or both.

To reduce your chance of having another stroke, you may be prescribed medicines. These include medicines to prevent blood clots, such as antiplatelet or anticoagulant medicines. Certain heart conditions can be treated with surgery to reduce the risk for more strokes. Surgery to open up a blockage in the carotid artery (endarterectomy) may also reduce the risk for future strokes.

You will likely need physical therapy, including speech and occupational therapy if appropriate. This can be done at home, at an outpatient office, or in a rehabilitation hospital. Which location depends on your needs and abilities.

Home care

  • Rest at home and don't exert yourself for the next few days.

  • If your healthcare provider has prescribed medicines, take them as directed.

Follow-up care

Follow up with your healthcare provider, or as advised. Additional tests may be needed. If you had an X-ray, CT scan, MRI, or ECG (electrocardiogram), it will be reviewed by a specialist. You will be notified of any new findings that will affect your care.

Call 911

Call 911 if any of these occur:

  • Any of your stroke symptoms worsen

  • Sudden new problems with speech, confusion, vision, walking, coordination, facial droop, or weakness or numbness on one side of your body

  • Severe headache, fainting spell, dizziness, or seizure

  • Chest pain or shortness of breath

Remember F.A.S.T. (described above). If you notice warning signs and symptoms of stroke, Call 911 right away.

Never drive yourself or the victim. The ambulance can alert the hospital and start treatment.
