Vestibular neuritis is inflammation of the vestibular nerve (the nerve in the ear that sends messages related to motion and position to the brain). [2] [3] [4] Both conditions involve inflammation of the inner ear. [5] Labyrinths that house the vestibular system sense changes in the head's position or the head's motion. [6]
In vestibular neuritis the onset of vertigo is sudden, and the nystagmus occurs even when the person has not been moving. [9] In this condition vertigo can last for days. [2] More severe causes should also be considered, [9] especially if other problems such as weakness, headache, double vision, or numbness occur. [2]

The vestibular nerve is one of the two branches of the vestibulocochlear nerve (the cochlear nerve being the other). In humans the vestibular nerve transmits sensory information from vestibular hair cells located in the two otolith organs (the utricle and the saccule ) and the three semicircular canals via the vestibular ganglion of Scarpa .
Neuritis is a general term for inflammation of a nerve [26] or the general inflammation of the peripheral nervous system. Symptoms depend on the nerves involved, but may include pain , paresthesia (pins-and-needles), paresis (weakness), hypoesthesia (numbness), anesthesia , paralysis , wasting, and disappearance of the reflexes .
The most common vestibular diseases in humans are vestibular neuritis, a related condition called labyrinthitis, Ménière's disease, and BPPV. In addition, the vestibular system's function can be affected by tumours on the vestibulocochlear nerve , an infarct in the brain stem or in cortical regions related to the processing of vestibular ...
As its name suggests, the test is subjective and cannot directly diagnose Acute Vestibular Syndrome (AVS), Ménière's disease, vestibular migraine, vestibular neuritis, or other central nervous system pathologies. [1]
Benign paroxysmal positional vertigo (BPPV) is a disorder arising from a problem in the inner ear. [3] Symptoms are repeated, brief periods of vertigo with movement, characterized by a spinning sensation upon changes in the position of the head. [1]
