What does the acronym "FAST" stand for in stroke recognition?

The acronym "FAST" is a critical tool in recognizing the signs of a stroke and facilitating prompt treatment. It stands for:

• Face drooping: This refers to an observable drooping or weakness on one side of the face when the person is asked to smile. This can indicate a problem with the brain's ability to control facial muscles.

• Arm weakness: This involves checking if one arm drifts downward when the person is asked to raise both arms. If weakness is present, one arm may not be lifted as high as the other or may fall unexpectedly.

• Speech difficulties: This component assesses if the person can speak clearly or if their speech is slurred or strange. Communication issues can be a sign of a stroke.

• Time to call emergency services: This emphasizes the urgency of the situation. If any of the above symptoms are noticed, it's crucial to call emergency services immediately, as timely treatment can significantly improve outcomes.

In contrast, the other options include variations of these symptoms but either misrepresent the specifics (like mentioning "strength" instead of "weakness" or including symptoms unrelated to the FAST acronym, such as sudden headache) or change the phrasing in ways that don't align with the established
