Spot a Stroke, Save a Life: Key Warning Signs Everyone Should Know

A stroke happens when blood flow to part of the brain is cut off—either by a clot (ischemic) or a burst vessel (hemorrhagic). Brain cells begin to die within minutes, so recognizing symptoms quickly and calling emergency services (e.g., 911 in the U.S.) can mean the difference between full recovery and long-term disability—or worse. Below is a concise, reader-friendly guide to the most common stroke warning signs, plus practical tips for what to do if you suspect one.

1. Remember “BE FAST”

Health organizations now favor BE FAST—an easy acronym that expands on the classic FAST test to catch even more stroke cases:

Letter Symptom to Check What You Might See or Feel
B – Balance Sudden loss of balance or coordination Unsteady walk, stumbling, dizziness
E – Eyes Sudden vision changes Blurry or double vision, loss of vision in one or both eyes
F – Face Facial drooping One side droops or feels numb; uneven smile
A – Arm Arm or leg weakness Inability to raise one arm, drifting downward, sudden numbness
S – Speech Speech difficulty Slurred or garbled words, inability to speak or understand
T – Time Call emergency services immediately Every minute counts—note the time symptoms started

Action step: If someone fails any part of the BE FAST check, call for an ambulance right away. Do not wait for symptoms to improve—they often worsen rapidly.

2. Additional Red-Flag Signs

While BE FAST covers most strokes, some people experience other sudden symptoms:

  • Severe, “thunderclap” headache with no known cause

  • Numbness or weakness on one side of the body (face, arm, leg)

  • Confusion or trouble understanding simple sentences

  • Difficulty swallowing or sudden drooling

  • Loss of consciousness or unexplained fainting

  • Sudden nausea or vomiting (especially with dizziness)

3. Why Speed Matters

  • 1.9 million brain cells die each minute a stroke goes untreated.

  • Thrombolytic (“clot-busting”) drugs must be given within about 3–4.5 hours of symptom onset to work safely.

  • Mechanical clot removal procedures are time-sensitive as well—typically up to 24 hours but most effective far sooner.

Simply put, the faster medical teams act, the better the odds of reversing damage.

4. What to Do While Waiting for Help

  1. Note the time symptoms began (or were last seen “normal”).

  2. Keep the person calm & seated upright if possible; avoid food, drink, or medications unless EMS directs.

  3. Loosen tight clothing to aid breathing.

  4. Prepare medical info: allergies, medications, health conditions.

  5. Do NOT drive yourself or the patient—ambulances provide lifesaving care en route and alert the hospital stroke team.

5. Risk Factors & Prevention Snapshot

Non-Modifiable Modifiable / Manageable
Age > 55 years High blood pressure (top risk)
Family history of stroke Smoking or vaping
Prior stroke/TIA Uncontrolled diabetes
Sex (men slightly higher overall risk; women more likely to die from stroke) High LDL cholesterol
Race/ethnicity (e.g., higher rates in Black & Hispanic populations) Atrial fibrillation (needs anticoagulation)
Sedentary lifestyle, obesity, excessive alcohol, high-salt diet

Prevention basics: keep BP, blood sugar, and cholesterol in check; move daily; eat plenty of fruits, veggies, and whole grains; quit smoking; limit alcohol; and follow your doctor’s advice on heart-rhythm issues.

Take-Home Message

  1. Learn BE FAST and practice spotting each sign.

  2. Call emergency services immediately—never wait for symptoms to subside.

  3. Share this knowledge with friends and family; you could save a life.
