What does the "F" in the FAST acronym stand for?

The "F" in the FAST acronym stands for "Face." This is a key component used in recognizing the signs of a stroke. When assessing someone for a possible stroke, observing the face is crucial because one of the classic symptoms is facial drooping. This occurs when the muscles on one side of the face become weak or paralyzed, leading to an uneven smile or difficulty in closing one eye. Early recognition of these symptoms is critical for effective treatment and can significantly affect recovery outcomes, making it vital to remember this aspect of the FAST assessment.

The other options do not pertain to the FAST acronym and therefore are not relevant for identifying the signs of a stroke.
