Treatment of Dizziness (Vertigo)
The primary treatment for benign paroxysmal positional vertigo (BPPV), the most common cause of vertigo, is canalith repositioning procedures (CRP) with success rates of 80-90% after 1-2 treatments, not medication. 1, 2
Diagnosis and Classification
Before treatment, proper diagnosis is essential:
- Peripheral vs. Central Vertigo: Distinguish using HINTS examination (Head-Impulse, Nystagmus, Test of Skew) 2
- BPPV Diagnosis: Confirmed with Dix-Hallpike test (gold standard) or supine roll test 1, 2
- Common Causes: BPPV (38.8%), vestibular migraine, vestibular neuritis, Menière's disease, and vascular causes 2, 3
Treatment Algorithm
1. BPPV (Most Common Cause)
First-line: Canalith Repositioning Procedures (CRP) such as Epley maneuver 1
- Success rate: 80-90% after 1-2 treatments
- Can be performed during diagnostic testing
- May cause brief distress, vertigo, nausea during procedure
For patients unable to undergo CRP (cervical stenosis, severe arthritis, obesity, etc.):
2. Vestibular Suppressant Medications
- Not recommended for routine BPPV treatment 1
- Short-term use only for severe symptoms or when CRP is delayed 1, 2
- Options include:
- Meclizine (FDA-approved for vertigo) 4
- Antihistamines
- Benzodiazepines (lorazepam)
- Dopamine receptor antagonists (prochlorperazine, metoclopramide)
3. Vestibular Rehabilitation
Indicated for:
- Patients who fail initial CRP
- Those with additional balance impairments
- Elderly patients with fall risk
- Patients with persistent symptoms after successful CRP 1
Components:
- Habituation exercises
- Balance retraining
- Gait training
- Fall prevention strategies 2
4. Specific Treatments for Other Vertigo Causes
Vestibular Neuritis/Labyrinthitis:
- Short course of oral corticosteroids (7-14 days with tapering)
- Antibiotics if bacterial cause suspected 2
Menière's Disease:
- Diuretics (reduce endolymph volume)
- Low-salt diet
- Transtympanic gentamicin for refractory cases with non-usable hearing 2
Vestibular Migraine:
- Beta-blockers, anticonvulsants, or antidepressants for prophylaxis 2
Central Vertigo (stroke, MS):
Follow-up and Monitoring
- Reassessment within 1 month after initial treatment to document resolution or persistence 1
- Monitor for recurrence: BPPV has 10-18% recurrence rate at 1 year, up to 36% long-term 2
Special Considerations
Elderly Patients
- Higher fall risk requires more aggressive management
- Home safety assessment recommended
- Consider vestibular rehabilitation even after successful CRP 1, 2
Persistent Symptoms
- If symptoms persist beyond 1 month despite appropriate treatment:
- Reassess diagnosis
- Consider additional vestibular testing
- Evaluate for comorbid conditions (anxiety, depression) 1
Common Pitfalls
- Overuse of vestibular suppressant medications which can delay vestibular compensation 2
- Failure to diagnose central causes of vertigo (stroke, MS) which require different management 5, 6
- Not addressing fall risk in elderly patients with vertigo 1, 2
- Missing BPPV diagnosis due to improper testing technique 1
Remember that while observation alone may lead to spontaneous resolution in 15-85% of BPPV cases within a month, active treatment with CRP provides faster symptom relief and reduces fall risk, especially in elderly patients 1.
