Every minute matters during a stroke. Brain cells begin dying within minutes of blood flow being interrupted, which is why recognizing the warning signs quickly—and acting on them immediately—can make the difference between a full recovery and permanent damage.
Most people have heard of the FAST acronym, and for good reason: it's simple, it's memorable, and it covers the most common stroke symptoms. But there's more to stroke recognition than FAST alone, including a warning sign that's easy to dismiss because it goes away on its own. Here's what to watch for, what to do, and why a vascular specialist is an important part of stroke prevention.
FAST: The Warning Signs to Know
FAST stands for:
- Face drooping — one side of the face droops or feels numb. Ask the person to smile; if the smile is uneven, that's a warning sign.
- Arm weakness — one arm feels weak or numb. Ask the person to raise both arms; if one arm drifts downward, that's a warning sign.
- Speech difficulty — speech is slurred, hard to understand, or the person can't speak at all. Ask them to repeat a simple sentence.
- Time to call 911 — if you notice any of these signs, even if they seem to pass, call 911 immediately. Note the time symptoms started—emergency responders and hospital staff will need this to determine treatment options.
Other stroke symptoms to watch for include sudden confusion, sudden trouble seeing in one or both eyes, sudden trouble walking, dizziness, loss of balance or coordination, and a sudden, severe headache with no known cause.
If you see any of these signs, call 911 right away. Don't wait to see if symptoms improve, and don't drive the person to the hospital yourself—emergency responders can begin treatment en route and alert the hospital before you arrive, which saves critical time.
The Warning Sign That's Easy to Miss: TIA
A transient ischemic attack, often called a TIA or "mini-stroke," causes the same symptoms as a stroke—facial drooping, arm weakness, slurred speech—but the symptoms resolve on their own, usually within minutes to a few hours. Because the symptoms go away, many people brush them off or assume nothing serious happened.
That assumption can be dangerous. A TIA is caused by a temporary blockage in blood flow to the brain, and it's one of the strongest warning signs that a full stroke may follow—often within days. Roughly one in three people who have a TIA will go on to have a stroke, and a significant portion of those happen within 48 hours of the TIA itself.
Any TIA symptoms, even ones that have already resolved, are a reason to seek medical attention right away. Don't wait to see if it happens again.
A TIA is also one of the clearest signals that it's worth talking to a vascular specialist about your stroke risk before a more serious event occurs.
Why a Vascular Specialist Matters for Stroke Prevention
Stroke is often thought of as a neurological or cardiac issue, but a significant number of strokes are caused by carotid artery disease—a narrowing of the arteries in the neck that supply blood to the brain, usually from a buildup of plaque. This is a vascular condition, and it's one that vascular surgeons are specifically trained to diagnose and treat.
Carotid artery disease often has no symptoms until it causes a TIA or stroke, which is why screening matters for people with risk factors like high blood pressure, high cholesterol, smoking history, diabetes, or a family history of stroke or vascular disease. A simple, non-invasive ultrasound can check blood flow through the carotid arteries and identify narrowing before it causes a stroke.
If narrowing is found, treatment options range from lifestyle and medical management to procedures that restore normal blood flow—decisions that depend on how severe the narrowing is and a person's overall health picture.
What to Do Right Now
- Learn FAST and share it with family members, especially those who are older or have risk factors for stroke.
- Know that TIA symptoms are never "nothing" — even if they resolve completely, they warrant medical evaluation right away.
- If you have risk factors for stroke—high blood pressure, high cholesterol, diabetes, smoking history, or a family history of stroke—ask about carotid artery screening, especially if you haven't had one before.
Vascular Associates of South Alabama offers stroke prevention screenings, including carotid artery ultrasound, for patients with risk factors for stroke. Contact our team to schedule a screening and get a clear picture of your risk.
