When a stroke hits, every minute costs brain cells. The F.A.S.T. check takes seconds and tells you exactly when to call for help.
Time is brain
A stroke happens when blood flow to part of the brain is suddenly cut off. Around 1.9 million neurons die every minute it goes untreated, so speed of response directly shapes how well someone recovers.
The good news: clot-busting treatment works best within the first few hours. Recognising the signs quickly is the most powerful thing a bystander can do.
F is for Face, A is for Arms
Ask the person to smile. Does one side of the face droop or feel numb? Then ask them to raise both arms. Does one drift downward or feel weak? Either sign on one side of the body is a red flag.
S is for Speech, T is for Time
Ask them to repeat a simple sentence. Is their speech slurred, jumbled, or are they unable to find words? If you see any of these signs, it is Time to call emergency services immediately.
Note the moment symptoms started; that timing decides which treatments are still possible. Do not wait to see if things improve, and do not drive yourself.
What not to do
Do not give food, drink, or medication, and do not let the person lie flat if they are struggling to breathe. Keep them calm, comfortable, and get expert help on the way fast.
