Vestibular Paroxysmia
Complete guide to understanding and treating vestibular paroxysmia
Vestibular paroxysmia (VP) accounts for approximately 3.7% of vestibular disorders. It occurs when arteries in the cerebellar pontine angle cause pressure-induced dysfunction of the eighth cranial nerve. The condition is characterized by brief, recurrent attacks of vertigo that typically respond well to anticonvulsant medication.
Key Symptoms & Signs
Primary Symptoms
- •Short attacks of spinning or non-spinning vertigo (seconds to minutes)
- •Multiple episodes per day (up to 30 or more)
- •Spontaneous or triggered by head position
- •Brief episodes of unsteadiness
- •Series of attacks common
Associated Features
- •Unilateral tinnitus during attacks
- •Temporary hearing changes
- •Symptoms may worsen with head movement
- •Hyperventilation may trigger attacks
- •Response to carbamazepine
Clinical Presentation
Diagnostic Features
Key clinical characteristics that help identify vestibular paroxysmia.
- •Very brief vertigo episodes
- •High frequency of attacks
- •Normal neurological exam
- •MRI shows neurovascular compression in 95% of cases
- •Responds to low-dose anticonvulsants
Risk Factors
Common factors associated with developing vestibular paroxysmia.
- •Two age peaks: young (vascular anomalies) and 40-70 years (vascular elongation)
- •Male predominance (2:1 ratio)
- •Arterial hypertension
- •Atherosclerosis
- •Vascular anatomical variations
Treatment Phases
Initial Medical Management
- •Carbamazepine 200-600mg/day
- •Oxcarbazepine 300-900mg/day
- •Monitor for side effects
- •Regular follow-up to assess response
Alternative Medications
- •Lamotrigine
- •Phenytoin
- •Gabapentin
- •Baclofen
- •Topiramate
Surgical Intervention
- •Microvascular decompression surgery
- •Careful patient selection
- •Risk-benefit assessment
- •Long-term outcome monitoring
