Vestibular neuritis is an inner ear disorder that may cause a person to experience such symptoms as sudden, severe vertigo (spinning/swaying sensation), dizziness, balance problems, nausea and vomiting.
What is the difference between vestibular neuritis and BPPV?
The main characteristic of VN is an acute onset of vertigo without hearing loss or tinnitus. Similarly to BPPV, symptoms of vertigo are aggravated by a change in the position of the head. Loss of balance is more prominent in VN, compared with other causes of vertigo, and patients may commonly present with falls.
Can you see vestibular neuritis on MRI?
Eight cases of vestibular neuronitis were studied with enhanced MRI. We did not detect any enhanced lesions of the vestibular nerve or ganglion. So far, as the present conditions of MRI are concerned, it is difficult to detect any enhancement in the vestibular nerve and ganglion.
Can vestibular disorders cause anxiety?
