A stroke is a medical emergency caused by interrupted blood flow to the brain. Early recognition is critical because fast treatment can reduce brain damage.
The most widely used way to remember warning signs is FAST.
🧠FAST warning signs of stroke
F — Face drooping
- One side of the face looks uneven
- Smile becomes lopsided
A — Arm weakness
- One arm drifts downward when both arms are raised
- Numbness or weakness on one side
S — Speech difficulty
- Slurred speech
- Trouble speaking or understanding words
T — Time to call emergency help immediately
- Even if symptoms go away
⚠️ Other early warning signs
1. Sudden numbness or weakness
- Face, arm, or leg (usually one side)
2. Sudden confusion
- Trouble understanding speech or thinking clearly
3. Vision problems
- Blurred vision
- Loss of vision in one or both eyes
4. Sudden dizziness or loss of balance
- Trouble walking
- Loss of coordination
5. Severe sudden headache
- Often described as “worst headache of life”
- More common in hemorrhagic stroke
🧠Important related condition
Some people experience a mini-stroke called a:
- Transient ischemic attack (TIA)
A TIA causes stroke-like symptoms that may disappear within minutes or hours—but it is a major warning sign of a future stroke.
🚨 What to do immediately
If any of these symptoms appear:
- Call emergency services immediately
- Do NOT wait to see if it improves
- Note the time symptoms started
🧾 Bottom line
Stroke signs usually appear suddenly and affect movement, speech, vision, or balance. FAST is the simplest and most reliable way to remember them.
