Imagine you're at dinner with a friend and they suddenly can't finish their sentence. Or maybe you notice one side of their face looks strange. Would you know what to do?
A stroke is a medical emergency that happens when blood flow to part of the brain is cut off. Brain cells begin dying within minutes. The faster someone gets treatment, the better their chances of surviving without lasting damage. That's why doctors say: time is brain.
For every minute a stroke goes untreated, a person loses about 1.9 million brain cells.
The FAST Method — Four Things to Check
Doctors and emergency workers use a simple memory tool called FAST. It stands for Face, Arms, Speech, and Time. If you see any of these signs, call 911 immediately.
Face drooping
Ask the person to smile. Does one side of their face droop or look uneven? Is their smile crooked?
Arm weakness
Ask them to raise both arms. Does one arm drift downward or feel weak and numb?
Speech difficulty
Ask them to repeat a simple sentence. Is their speech slurred, strange, or hard to understand?
Time to call 911
If you notice ANY of these signs — even just one — call 911 right away. Note the exact time symptoms started.
🚨 Call 911 immediately — do not drive to the hospital yourself.
Ambulances can begin treatment on the way and alert the hospital so a stroke team is ready the moment you arrive.
Other Warning Signs to Watch For
FAST covers the most common stroke symptoms, but a stroke can show up in other ways too. Be alert for any of these:
- 👁Sudden trouble seeing in one or both eyes — blurry or double vision, or vision that goes dark
- 🤕A sudden, severe headache with no known cause — sometimes described as "the worst headache of my life"
- 😵Sudden dizziness, loss of balance, or difficulty walking or coordinating movements
- 😶Sudden numbness or weakness in the face, arm, or leg — especially on one side of the body
- 😕Sudden confusion or trouble understanding what people are saying
Why You Should Never "Wait and See"
One of the most dangerous things people do is wait to see if symptoms get better on their own. Sometimes stroke symptoms do go away temporarily. This is called a TIA (transient ischemic attack), often called a "mini-stroke." But a TIA is a serious warning sign — it means a full stroke may be coming soon.
What Happens When You Call 911
Note the exact time symptoms started
Doctors need this to decide what treatments are safe. Even if you're not sure, give your best estimate.
Keep the person calm and still
Have them sit or lie down in a safe position. Don't give them food, water, or medications.
Stay on the line with the dispatcher
The 911 operator will guide you and alert the hospital, so a stroke team is ready when you arrive.
Gather their medications if possible
If you can quickly grab a list of their medications or pill bottles, bring them — this helps doctors treat safely.
