Standardizing your approach to dizziness and vertigo
First, determine whether the sensation the patient is experiencing is dizziness or true vertigo. Then eliminate ominous causes from the array of benign ones.
PRACTICE RECOMMENDATIONS
› Employ the Dix-Hallpike maneuver to diagnose patients presenting with dizziness with features suggestive of benign paroxysmal positional vertigo (BPPV). A
› Use the head impulse, nystagmus, test of skew (HINTS) examination to differentiate between central and peripheral vestibular causes of dizziness and rule out stroke. B
› Prescribe betahistine only for patients with Meniere’s disease and not for patients with other causes of dizziness and/or vertigo. B
› Rely on antiemetics, antihistamines, and benzodiazepines to manage acute and brief episodes of vertigo, but not to treat BPPV because they blunt central compensation. C
Strength of recommendation (SOR)
A Good-quality patient-oriented evidence
B Inconsistent or limited-quality patient-oriented evidence
C Consensus, usual practice, opinion, disease-oriented evidence, case series

Management starts with primary and secondary prevention
Patient education is essential for avoiding potential triggers of dizziness. Patients with orthostatic hypotension should be educated about the need to correct the underlying mechanism, including the need for adequate hydration and recognition of offending medications and contributory conditions/situations (caffeine, heat, standing quickly).17 Encouraging balance maintenance through exercise and physiotherapy can help with gait and musculoskeletal disorders, and reducing harmful habits (smoking, poor diet, no exercise) can lead to overall improved cardiovascular health.32 Advise those with Meniere’s disease to avoid potential triggers such as caffeine, high sodium foods, and alcohol.33
