and TIA.

## 2. Weakness on One Side of the Body
A person experiencing a stroke may suddenly have difficulty using one arm or leg.
One simple check is to ask the person to raise both arms.
If one arm:
* Cannot be raised normally
* Feels unusually weak
* Drifts downward
it may indicate a neurological emergency.
Sudden arm weakness is part of the **B.E. F.A.S.T.** stroke-recognition system.
## 3. Facial Drooping
Look closely at the person’s smile.
