What is a stroke?

There are 2 types of stroke – bleeding stroke (hemorrhagic) and clotting stroke (ischemic).

  • Some causes of a bleeding stroke are:
    • High blood pressure (hypertension)
    • Aneurysm rupture (subarachnoid hemorrhage)
    • Vascular malformation (abnormal blood vessels)
  • clotting stroke (ischemic stroke) happens when an artery in the brain is blocked by a blood clot and oxygen cannot get to the brain.

What are the signs of a stroke?

There are many signs of a stroke.  Any sudden change in your body could be a stroke. Common signs of stroke are:

  • Balance problems
  • Trouble walking
  • Dizziness
  • Vision loss or double vision
  • Face drooping or twisting
  • Weakness on one side of the body
  • Numbness on one side of the body
  • Trouble talking or understanding

The acronym BE-FAST can help you remember the common signs of stroke.

What are risk factors for a Stroke?

Risk factors you can control (called Modifiable Risk Factors)

  • High Blood Pressure
  • Smoking
  • Diabetes
  • Heart Disease
  • Peripheral Vascular Disease
  • Atrial Fibrillation
  • Atherosclerosis
  • High Blood Cholesterol
  • Diets high in saturated and trans fats and high in cholesterol
  • Physical Inactivity
  • Obesity
  • Alcohol and Drug Abuse

Risk Factors you have no control over (called Non-Modifiable Risk Factors)

  • Advanced Age
  • Family History of Stroke
  • Genetic Disorders
  • Personal History of Prior Stroke or TIA
  • Personal History of Prior Heart Attack

What if the stroke signs or symptoms go away?

Stroke signs that go away completely in a short time are called a transient ischemic attack or “TIA”. A TIA happens when the blood clot causing the symptoms goes away. A TIA is a warning sign that a bigger stroke could happen soon. Anyone with stroke signs should go to the hospital immediately, even if they go away. In the hospital you will get tests and medication that can prevent a bigger stroke.

What should I do if I experience stroke signs or symptoms?

Call 911 and say, “I am having a stroke”. Go to the closet hospital. Stroke is an emergency. The treatment for stroke must be given right away. People do better if they are treated fast.
