TIA can temporarily weaken the muscles on one side of the face.
You may notice that:
* One corner of the mouth droops
* The smile becomes uneven
* One eye or side of the face appears lower
* The person says their face feels numb
The **F in FAST** stands for Face because facial drooping is one of the classic warning signs.
Ask the person to smile. If one side does not move normally, treat it as an emergency.
