Which finding warrants stroke evaluation in a patient with dizziness?

• A. Focal neurologic symptoms such as dysphagia, facial droop, trouble speaking, ataxia, or diplopia
• B. Hearing loss only
• C. Recent infections
• D. Tinnitus

Answer: (A)

The key concept is that dizziness with accompanying focal neurologic signs points toward a cerebrovascular event and necessitates urgent stroke evaluation. When dizziness is paired with deficits like difficulty swallowing, facial droop, trouble speaking, ataxia, or double vision, these signs localize to brain regions controlling language, facial movement, coordination, and eye movements, making stroke the top concern. This warrants immediate imaging and activation of the stroke protocol to determine eligibility for reperfusion therapy and to rule out hemorrhage. Hearing loss by itself can arise from inner ear disorders such as vestibular neuritis or otitis media, which do not imply an acute central stroke. Tinnitus can accompany benign vertigo or peripheral causes and likewise does not by itself mandate emergent stroke workup. Recent infections may be linked to peripheral vertigo or labyrinthitis rather than a central vascular event. So, while those features may explain dizziness, they lack the focal neurologic evidence that makes urgent stroke evaluation necessary.
