A stroke is a medical emergency. Recognizing early signs quickly can save brain function and life.
A useful way to remember key symptoms is the FAST stroke recognition system.
The FAST warning signs
F — Face drooping
- One side of the face may droop or feel numb
- Ask the person to smile—one side may look uneven
A — Arm weakness
- One arm may drift downward when both are raised
- Numbness or weakness on one side of the body
S — Speech difficulty
- Slurred speech or trouble speaking
- Person may sound confused or unable to form words
T — Time to call emergency services
- If any of these signs appear, seek immediate medical help
Other early warning signs of stroke
- Sudden confusion or trouble understanding speech
- Sudden vision problems in one or both eyes
- Sudden severe headache with no known cause
- Sudden dizziness or loss of balance/coordination
- Numbness or weakness in face, arm, or leg (especially one side)
- Difficulty walking or unsteady movement
- Sudden trouble seeing (blurred or double vision)
- Loss of coordination or “drunk-like” movement
- Sudden trouble swallowing
- Sudden collapse or loss of consciousness (in severe cases)
Important note
- Strokes often happen suddenly, without warning
- Even if symptoms disappear quickly (possible TIA or “mini-stroke”), it still requires urgent evaluation
- Immediate treatment can greatly reduce brain damage
Bottom line
The key message is simple:
Any sudden one-sided weakness, speech trouble, or facial droop = emergency. Don’t wait.
If you want, I can also explain the difference between stroke, TIA, and migraine symptoms, since they can sometimes look similar.
