What does the 'F' in the FAST acronym refer to?

The 'F' in the FAST acronym stands for "Face," specifically checking for facial droop or asymmetry when the person is asked to smile. This is a critical component of assessing someone for a stroke, as facial drooping can indicate that a part of the brain may not be functioning properly due to a blockage of blood flow or hemorrhage. The ability to smile symmetrically can help determine neurological function, which is essential for timely and appropriate medical intervention. Recognizing these symptoms promptly can significantly affect outcomes in stroke management, making this check a vital part of the FAST assessment.
