What does the FAST exam assess in suspected stroke?

• A. Balance and coordination.
• B. Vision changes and hearing loss.
• C. Dizziness and nausea.
• D. Face drooping, Arm weakness, Speech difficulties; Time to call emergency.

Answer: (D)

Recognizing stroke signs quickly using a simple FAST screen is aimed at identifying sudden, focal deficits that require urgent treatment. The FAST exam focuses on three hallmark signs: facial weakness (one side of the face droops), arm weakness (one arm drifts downward when both arms are raised), and speech difficulties (trouble speaking or understanding speech). When any of these signs are present, it strongly suggests a stroke affecting brain areas that control face, arm movement, and language, and it triggers the imperative to call emergency services immediately. Time matters because treatments to restore blood flow are most effective within narrow windows, so starting urgent evaluation and transport right away can significantly impact outcomes. While dizziness, vision changes, or nausea can occur with stroke, they are less specific, and FAST prioritizes the most indicative, rapid signs that point to a possible stroke.
