Ischemic Stroke
Is my patient’s vertigo due to stroke?
Differentiate central from peripheral vertigo. Use HINTS when neurovestibular exam expertise is available, or the Sudbury Vertigo Risk Score when a simpler, clinically-based assessment is preferred.
Diagnosis
HINTS for Stroke in Acute Vestibular Syndrome
Accurate bedside test that may perform better than early MRI
Use this tool when
Concern for central cause of continuous vertigo; requires exam expertise
Prognosis
Sudbury Vertigo Risk Score
Simpler stroke risk estimate using easily obtained clinical variables
Use this tool when
Acute vertigo when HINTS exam expertise is limited
