Which sign would prompt stroke or TIA screening in a patient presenting with dizziness?

• A. Sudden unilateral facial droop, arm weakness, or speech difficulty (FAST)
• B. Sudden severe dizziness with gait disturbance or limb weakness
• C. Numbness or confusion
• D. Time of onset is critical

Answer: (A)

The key idea is that acute focal neurological deficits signal a possible cerebrovascular event. Sudden unilateral facial droop, arm weakness, or speech difficulty are classic signs of a stroke and mean there is likely brain involvement rather than a peripheral cause. When dizziness is the presenting symptom, these focal signs prompt urgent stroke/TIA screening and imaging because they indicate an urgent vascular problem that may benefit from time-sensitive treatment. Other statements—like dizziness with gait disturbance or limb weakness, numbness or confusion without a clear focal deficit, or notes about time of onset alone—are less specific indicators for stroke screening, even though timing is important for treatment decisions. This is why the presence of facial droop, arm weakness, or speech difficulty is the strongest trigger for stroke screening in a dizzy patient.
