Comprehensive Diagnostic & Therapeutic Reference Profile
Also known as: Vestibular Neuronitis, Acute Peripheral Vestibulopathy, Acute Vestibular Syndrome.
Vestibular neuritis is an acute, self-limiting disorder characterized by sudden, severe vertigo caused by inflammation of the vestibular nerve, the branch of the vestibulocochlear nerve (CN VIII) responsible for balance. It typically manifests as intense rotatory vertigo, nausea, and postural imbalance without associated hearing loss.
The precise etiology remains debated, but it is widely attributed to a viral infection, specifically the reactivation of the herpes simplex virus type 1 (HSV-1) in the vestibular ganglion. Other potential triggers include post-viral inflammatory responses or vascular compromise of the vestibular labyrinth.
Inflammation of the vestibular nerve disrupts the transmission of tonic neural signals from the semicircular canals to the vestibular nuclei in the brainstem. This creates an asymmetric input (vestibular tone imbalance), where the brain perceives the body as rotating despite being stationary, resulting in vertigo and spontaneous nystagmus.
Vestibular neuritis accounts for approximately 5-10% of patients presenting to emergency departments with dizziness. It typically affects adults aged 30–60 years, with no significant gender predilection.
Upper respiratory tract infections, immune suppression, and periods of physical or emotional stress.
A. Early Symptoms
Examination typically reveals unidirectional, horizontal-torsional nystagmus that increases when gazing away from the affected side. The Head Impulse Test (HIT) is typically positive (abnormal) toward the side of the lesion.
A. Clinical Assessment: Bedside examination (HINTS exam).
B. Laboratory Testing: Generally not required; blood tests to rule out mimics.
C. Imaging Studies: MRI to exclude central vertigo (stroke).
D. Functional Tests: Videonystagmography (VNG).
E. Biopsy Findings: N/A.
F. Genetic Testing: Not indicated.
G. Differential Diagnosis: Meniere’s disease, Labyrinthitis, Cerebellar stroke.
Complete Blood Count
Type: Blood Test
Purpose: Screen for systemic infection.
Expected Findings: Normal or slightly elevated white blood cells.
Interpretation: Non-specific; helps exclude inflammatory processes.
MRI of the Brain/Internal Auditory Canal: Purpose is to rule out stroke or vestibular schwannoma. Findings usually show no pathology, confirming a peripheral vestibular origin.
Labyrinthitis (includes hearing loss), Meniere’s disease (recurrent), Vestibular Migraine (associated with aura/headache), Cerebellar Stroke (HINTS-plus exam can differentiate).
Development of BPPV, persistent postural-perceptual dizziness (PPPD), and chronic gait instability in elderly patients.
A. Lifestyle Modifications: Bed rest in the acute phase.
B. Preventive Measures: None known.
C. Medical Treatment:
Good; most patients experience significant resolution of vertigo within 7–14 days. Vestibular compensation typically occurs within weeks, though some instability may persist during rapid head movements.
No primary prevention exists due to the presumed viral etiology.
The following homeopathic remedies have been historically indicated for symptoms associated with Vestibular Neuritis. Selection should be based on individualized symptom totality and constitutional assessment.
