Stroke Awareness Mo

As a leading cause of death in the U.S., strokes represent a threat to us all. In fact, the U.S. Centers for Disease Control and Prevention (CDC) reports that an American dies of a stroke every four minutes. In honor of May’s status as National Stroke Awareness Month, here is a primer on the basics of stroke, how to control your risk of having a stroke, and how you can stay aware of this significant threat.

What Happens During a Stroke?

You may be familiar with the concept of a stroke, but you may not understand the specifics of the disease. A stroke is known to medical professionals as a cerebral vascular accident, or CVA. During a stroke, your brain tissue becomes damaged. Most commonly, strokes happen when a blood vessel that supplies the brain becomes blocked, causing a decrease in the brain’s blood flow, an event known as ischemia. The CDC reports that ischemic strokes account for 87% of all strokes.

Less commonly, a stroke can be hemorrhagic, meaning that brain tissue becomes damaged by excessive bleeding that occurs when a blood vessel bursts.

Whether ischemic or hemorrhagic, stroke experts caution that “time is brain.” This means that the earlier a stroke is identified, the better a person’s odds of receiving brain-sparing therapy.

Who Is at Risk of Having a Stroke?

A stroke can affect anyone, but the following risk factors can increase your likelihood of having a stroke.

  • Age: Americans over the age of 65 have a higher risk of stroke, with nearly 75% of strokes affecting people in this age group.
  • Ethnicity: The CDC reports that the risk of stroke for black Americans is double that of white Americans, and Black Americans have the highest stroke death rate.
  • Geographical location: People who live in the southeastern United States have a higher likelihood of dying from a stroke.
  • Health history: Having a medical condition such as high blood pressure, high cholesterol, diabetes, nicotine abuse, or obesity can increase your risk of stroke.
  • Previous stroke: The CDC reports that almost a quarter of strokes occur in people who have previously had a stroke.

While these risk factors may seem intimidating, your risk of stroke is largely under your control. In fact, experts report that up to 80% of strokes can be prevented when you adopt a healthy lifestyle.

How to Recognize a Stroke

Outside of being aware of stroke risk factors, one of the most important ways to enhance your awareness of strokes is to become familiar with the symptoms of a stroke. Many leading stroke authorities use the F.A.S.T. acronym to teach stroke recognition; its components stand for Face drooping, Arm weakness, Speech difficulty, and Time to call 9-1-1.

To quickly assess someone using F.A.S.T., you can perform the following series of simple commands:

  • Ask them to smile and evaluate for any facial asymmetry.
  • Ask them to raise their arms forward and evaluate any arm drifting or dropping.
  • Ask them to repeat a simple sentence and evaluate for speech garbling or slurring.
  • Call 9-1-1 if someone is showing these symptoms, even if they are otherwise acting normally or the symptoms seem to be resolving.

Other indications of a stroke can include the sudden development of the following symptoms:

  • Confusion
  • Difficulty walking
  • Numbness
  • Severe headache
  • Visual changes

The American Stroke Association also cautions that a specific type of stroke, known as a posterior circulation stroke, can cause a different set of symptoms, such as dizziness, vertigo, balance problems, or nausea and vomiting. If you or a loved one experiences a sudden onset of these symptoms, you should call 9-1-1 immediately.

Preventing Strokes

The best way to decrease your chance of having a stroke is to stay educated on stroke prevention. If you already have a medical condition that may predispose you to stroke, you can lower your risk by getting regular medical evaluations and taking your medication exactly as directed.
