Warning Signs of Stroke: What to Watch for and When to Act

A stroke is a medical emergency that occurs when the blood supply to a part of the brain is interrupted or reduced, depriving brain cells of oxygen and nutrients. Without quick intervention, brain cells begin to die, leading to permanent damage or even death. Recognizing the signs of a stroke and seeking immediate medical attention can make a life-saving difference.

Understanding the Different Types of Stroke

There are two main types of stroke:

Ischemic Stroke – The most common type, accounting for about 87% of all strokes. It occurs when a blood clot blocks a blood vessel in the brain, cutting off oxygen supply.
Hemorrhagic Stroke – Caused by a ruptured blood vessel, leading to bleeding in or around the brain. This type of stroke can be more severe and often requires surgical intervention.
Transient Ischemic Attack (TIA) – Sometimes called a “mini-stroke,” a TIA is a temporary blockage of blood flow to the brain, often lasting only a few minutes but serving as a critical warning sign of a future stroke.

Common Signs and Symptoms of Stroke

The warning signs of a stroke can vary depending on the part of the brain affected, but common symptoms include:

Sudden Numbness or Weakness – Often affecting one side of the body, including the face, arm, or leg.
Confusion and Trouble Speaking – Difficulty understanding speech or forming coherent sentences.
Vision Problems – Sudden blurred or double vision in one or both eyes.
Severe Headache – A sudden, intense headache that may be accompanied by dizziness, nausea, or vomiting.
Loss of Balance or Coordination – Sudden difficulty walking or maintaining balance.

The FAST Method for Recognizing Stroke

The FAST method is a simple way to remember the most common signs of a stroke:

F – Face Drooping – One side of the face droops or feels numb. Ask the person to smile, and check for unevenness.
A – Arm Weakness – One arm feels weak or numb. Ask the person to raise both arms and see if one drifts downward.
S – Speech Difficulty – Speech may be slurred, hard to understand, or completely absent. Ask the person to repeat a simple sentence.
T – Time to Call 911 – If you observe any of these symptoms, call 911 immediately. Time is critical in reducing long-term damage.

Certain factors can increase your risk of stroke, including:

High blood pressure
Smoking
Diabetes
