Vestibular Neuritis Labyrinthitis
Vestibular neuritis (VN) is characterized by a sudden onset of vertigo or dizziness, often accompanied by nausea and vomiting. These symptoms usually last for several hours and decrease gradually over three to five days.
Once symptoms pass, you may be fairly comfortable when lying down or sitting still. Walking or moving your head quickly may result in unsteadiness, nausea or blurred vision.
Causes of Vestibular Neuritis
VN occurs when the nerve that connects the inner ear to the brain becomes inflamed due to:
- Herpes virus
When the nerve becomes inflamed, the information from the inner ear on that side is reduced suddenly, and sometimes drastically. The severity of VN can range from mild temporary inflammation that ends in a few days with no lingering problems, up to total and permanent destruction of the nerve pathway. Typically, it falls between these two extremes.
Vestibular Neuritis Treatment
Taking anti-nausea medication or an imbalance drug for three to five days may relieve VN. In addition, rehabilitation balance exercises should begin once the acute phase has passed. This will retrain the brain to use information provided by the inner ear. Exercises are most effective if you are not taking any sedating medication (such as Antivert).
