Vestibular neuritis accounts for approximately 7% of patients who consult with vertigo 1. It has a male/female ratio of 1/1 and the most common age of onset is between 30 and 60 years old, with a peak at between 40 and 50 years old. It has an annual incidence of between 1.7 (United Kingdom) and 3.5 (Japan) cases/100,000 people 2. The underlying causes may be viral infection or a vascular origin in patients with a history of hypertension.
The symptoms are a combination of severe rotatory vertigo, nausea and vomiting but without tinnitus or hearing loss. The severity of symptoms is extremely incapacitating and patients often need to stay in bed (for up to 2 days). This is a reason for visiting the emergency room.
The severity of symptoms, the generated disabilities and long-term complications of the disease process emphasize the need for specific treatments.
Current treatment involves two stages:
