How to Spot the Warning Signs of a Stroke

Apr 28, 2022

As we age, our risk of having a stroke increases. That is why it is important for our patients to understand the warning signs of a stroke as well as causes, symptoms, and how to prevent them. Here’s what to do if a stroke occurs. 

What is a stroke

A stroke is when blood supply to a certain area of the brain is interrupted. As a result, the brain is unable to get the necessary oxygen and nutrients that it needs to function properly. 

The three main types of stroke are:

  • Ischemic Stroke
  • Hemorrhagic Stroke
  • Transient Ischemic Attack (TIA)

Ischemic strokes make up 87 percent of all strokes. They occur when a vessel supplying blood to the brain is blocked. Hemorrhagic strokes are caused by a weakened vessel that ruptures and bleeds into the surrounding brain. They make up approximately 13 percent of strokes. A Transient Ischemic Attack, also known as a mini-stroke, is a temporary interruption of blood flow to the brain. This type of stroke may signal that a major stroke is ahead; however, they are often overlooked. 

Each year, nearly 140,000 Americans die of a stroke, according to the CDC. Some of those deaths can be prevented if people get help quickly when the stroke begins. That is why we need to understand the warning signs and symptoms so that you or a loved one can act fast. 

What are the warning signs of a stroke?

Use the acronym, F.A.S.T, from the American Stroke Association to spot the signs of a stroke and know when to contact emergency medical services.

F.A.S.T stands for:

  • Face Drooping
  • Arm Weakness
  • Speech
  • Time to Call 9-1-1

Face drooping is when one side of the face looks saggy compared to the other--especially when they smile. Arm weakness really includes any limb that doesn’t move when your brain tells it to. The speech symptoms include slurred speech but can also present as trouble with words or “word salad” where the words sound correct but don’t make any sense together. Any of these symptoms are an indication to call emergency services to rule out a stroke.

Other symptoms include:

  • Numbness
  • Confusion
  • Trouble seeing
  • Trouble walking
  • Severe headache

If you or someone you know has any of the listed symptoms, it is important to contact 9-1-1 as quickly as possible. Knowing these warning signs and acting fast can lead to a successful recovery and significantly decrease the amount of damage to the brain. Even if the symptoms seem to go away, this might have been a mini-stroke. Many mini-strokes precede full strokes, so it is important to seek medical attention even if the concerning symptoms resolve on their own.

Stroke risk factors

Although there are a few risks that we do not have control over, such as aging, there are several other factors that can be both treated and controlled by you and your care team.

Some of these risk factors include:

Right side vs. left side stroke

Strokes can affect both sides of the brain–the right and left. If a stroke occurs on the right side of the brain, the left side of the brain will be affected, and vice versa when a left-side stroke occurs. 

Changes that may happen after a right-side stroke include: 

  • Paralysis on the left side of the body
  • Vision problems
  • Quick, inquisitive behavioral style
  • Memory loss

Changes that may happen after a left-side stroke include: 

  • Paralysis on the right side of the body
  • Speech/language problems
  • Slow behavior style
  • Memory loss
