Vestibular Hypofunction

What is Vestibular Neuronitis?

Vestibular Neuronitis is a condition caused by a viral infection that attacks the vestibular nerve which supplies communication between the inner ear and brain stem. Usually there is a gradual onset of vertigo, nausea, and vomiting over hours. The person’s symptoms usually peak in 24 hours, but can last 3 to 4 days. After the episode declines the person may have sensitivity to head movements, overall disequilibrium (particularly in the dark and when encountered with “busy” visual environments), and motion sensitivity. This sensitive may last for several weeks.

What is Labyrinthitis?

Labyrinthitis is very similar to Neuronitis since it is usually caused by a viral infection. The main difference is the person will experience hearing loss with the episode. Usually there is a gradual onset of hearing loss, vertigo, nausea, and vomiting either abruptly or over several hours. The symptoms will peak in 24 hours, but can last 3 to 4 days. After the episode declines, the person is usually left with persistent hearing loss. They may have sensitivity to head movements, overall disequilibrium (particularly in the dark and when encountered with “busy” visual environments), and motion sensitivity. This sensitivity may last for several weeks.
