Differences between vestibular neuritis and otolith disease

The differences between vestibular neuritis and benign paroxysmal positional vertigo (BPPV) mainly include pathogenesis, predisposing factors, and symptom presentation.

1. Pathogenesis

Vestibular neuritis is usually caused by a viral infection of the vestibular nerve. BPPV is a functional disorder of the vestibular labyrinth, typically associated with structural changes or damage within the vestibular labyrinth.

2. Predisposing Factors

Risk factors for vestibular neuritis include viral infections such as influenza, mumps, measles, and others. Common risk factors for BPPV include head trauma, advancing age, and changes in body position.

3. Symptom Presentation

Common symptoms of vestibular neuritis include dizziness, vertigo, nausea, vomiting, and nystagmus. Severe symptoms typically last about one week, followed by milder symptoms that may persist for several weeks to months. Symptoms of BPPV are often characterized by sudden episodes of vertigo, balance disturbances, nausea, and vomiting. These symptoms become particularly pronounced with significant changes in body position.
