Stroke warning sign acronyms drive 911 calls, F.A.S.T. leads in symptom recall for public

When it comes to prompting people to call 911 at the first sign of stroke, both F.A.S.T. and BE-FAST stroke warning signs acronyms were equally effective. However, people remembered the key stroke warning signs (face, arm and speech) better with the F.A.S.T. acronym, according to a preliminary study presented at the American Stroke Association’s International Stroke Conference 2025, held in Los Angeles, Feb. 5–7, 2025.
