What are the signs of a stroke as per the FAST acronym?

The FAST acronym is a widely recognized and effective tool for identifying the signs of a stroke quickly. Each component of FAST helps to highlight critical indicators that can suggest a stroke is occurring.

"Face drooping" refers to the asymmetrical appearance of the face, often most noticeable when the person is asked to smile. One side may droop downward, which is a telltale sign of potential stroke pathology affecting facial muscles.

"Arm weakness" indicates that one arm may not rise as high as the other when both arms are extended. This weakness can result from the brain's compromised ability to send signals to muscles due to a stroke.

"Speech difficulties" encompass slurred or confused speech, suggesting that the brain regions responsible for language may be affected, causing trouble in articulating words or understanding spoken language.

Lastly, "Time to call emergency services" is a critical reminder that prompt action is essential when stroke symptoms manifest, as early treatment can significantly impact recovery and outcomes.

This collection of signs is vital for public awareness and immediate response, making it a cornerstone of stroke recognition and response protocols.
