## 3. Facial Drooping
A 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.
## 4. Trouble Speaking or Understanding Words
A TIA can temporarily affect the areas of the brain responsible for language.
Someone may suddenly:
* Slur words
* Speak strangely
* Struggle to find simple words
* Say sentences that do not make sense
* Be unable to understand what others are saying
Speech difficulty is one of the central FAST warning signs.
Ask the person to repeat a simple sentence. Any sudden abnormal speech should be taken seriously.
