Low risk (score <5):

• Imaging is generally unnecessary if no red-flag features are present.
• Manage benign causes (e.g., BPPV) and provide symptom relief.
• Discharge with return precautions, and arrange outpatient follow-up.

Moderate risk (score 5–8):

• If a peripheral cause is uncertain, obtain MRI (± vascular imaging).
• Tailor further work-up to clinical suspicion, comorbidities, and social factors.

High risk (score >8):

• Expedite evaluation and neuroimaging (MRI/A or CT/A) for a central cause of vertigo.
• Optimize cardiovascular risk factors.
• Consider admission for further workup and management.
