"FAST" is an acronym used to help people recognize the signs of a stroke. It stands for Face, Arms, Speech, and Time. If someone’s face droops on one side, or if they can’t lift both arms, or if their speech is slurred, these are warning signs that they may be having a stroke. Recognizing these symptoms quickly is crucial because immediate medical attention can save lives and reduce long-term effects. The "Time" part emphasizes the importance of calling emergency services right away if you notice any of these signs. Remember, acting fast can make all the difference!
