Recognizing the signs of a stroke quickly can save a life. A stroke happens when blood flow to part of the brain is suddenly blocked or when a blood vessel in the brain bursts. Without oxygen-rich blood, brain cells begin to die within minutes.
That’s why time is critical. The faster a stroke is spotted and treated, the better the chances of survival and recovery. But many people don’t know the symptoms or brush them off, thinking they’ll go away. Understanding how to recognize a stroke—and acting fast—can make all the difference.
Experts use a simple method called F.A.S.T. to help people remember the main warning signs. F is for Face drooping, A is for Arm weakness, S is for Speech difficulty, and T is for Time to call emergency services.
If someone’s face suddenly looks uneven, if one arm can’t be lifted, or if their speech becomes slurred or strange, it’s time to call for help right away. Even if the symptoms go away after a few minutes, it may have been a transient ischemic attack (TIA), often called a mini-stroke, which is a serious warning sign that a bigger stroke may be coming soon.
Research published in the journal Stroke shows that using the F.A.S.T. method helps people recognize over 80% of strokes caused by blocked blood flow (ischemic strokes), which are the most common type.
But there are also other symptoms to watch out for, especially in strokes that affect the back part of the brain (posterior strokes). These may include sudden vision problems in one or both eyes, dizziness, trouble walking, or a sudden severe headache with no known cause.
One study from the American Heart Association found that people often delay seeking help because they don’t realize what’s happening. Some assume they’re just tired, dehydrated, or stressed.
Others wait to see if the problem goes away. But every minute counts. According to the National Institutes of Health, nearly two million brain cells can die each minute a stroke goes untreated.
There are also differences in how strokes can appear in women, who may experience symptoms like sudden confusion, trouble breathing, nausea, or even fainting. Because these signs aren’t always included in traditional stroke awareness campaigns, strokes in women are sometimes missed or misdiagnosed.
If you think someone might be having a stroke, don’t wait. Call emergency services immediately. Paramedics can start treatment faster than if you try to drive someone to the hospital yourself.
Hospitals also have special stroke teams that can give medications like tPA, a clot-busting drug, within a few hours of the first symptoms. If given early, this treatment can greatly reduce damage and improve recovery.
It’s also important to learn the risk factors that make a stroke more likely, such as high blood pressure, smoking, diabetes, high cholesterol, and a family history of stroke. But even people without these risk factors can still have a stroke, so being able to recognize the signs is essential for everyone.
In the end, knowing the signs of a stroke and acting quickly can mean the difference between a full recovery and lasting damage—or even death. Keep the F.A.S.T. test in mind, trust your instincts, and never wait to call for help. When it comes to stroke, every second truly matters.
