Recognising a Stroke: Know FAST and Act Without Delay
Sudden face weakness, arm weakness or speech difficulty can be an emergency. Learn the FAST signs and the next step.
Stroke symptoms usually begin suddenly. Recognising the change and getting emergency help quickly matters more than trying to work out the cause at home. A stroke can happen at any age, so do not dismiss a new symptom simply because someone is young or normally well.
Remember FAST
- Face: has one side of the face become weak or started to droop?
- Arms: can the person raise both arms and keep them raised, or is one weak or numb?
- Speech: is speech suddenly slurred, unusual or difficult to understand?
- Time: call 112 for emergency help in India if you suspect a stroke.
There can be other sudden signs
A stroke can also cause sudden trouble seeing, loss of balance, difficulty walking, confusion or a severe headache with no known cause. FAST is a helpful reminder, but it does not describe every possible stroke symptom.
Do not wait for every sign to appear. Get urgent help even if the symptoms seem to improve or disappear. A brief episode can still need emergency assessment.
Help the emergency team
Note when the symptoms were first noticed. If you know when the person was last without symptoms, share that information too. Tell the emergency team what changed and follow the dispatcher's instructions.
Use emergency medical transport rather than driving yourself. Do not delay the call to arrange an outpatient visit or collect every previous report. Prompt assessment allows the medical team to identify the cause and decide on the treatment that is appropriate.
Have the conversation before an emergency
Share the FAST reminder with the people you live with. Keep your address and essential contact information easy to find. If you are supporting an older relative, make sure family members know that sudden speech or movement changes require an immediate response.
