Neurogenic vestibular evoked potentials in three cases of vestibular system dysfunction.

Objectives: To demonstrate that neurogenic vestibular evoked potentials (NVsEP) may be specific to the vestibular system using three cases of vestibular system dysfunction and normal auditory function,

Methods: Neurogenic vestibular evoked potentials were performed by recording from the parietal areas of the scalp using a tone-pip auditory stimulus via headphones. Brainstem auditory evoked potentials (BAEPs) and NVsEP were performed in all three cases.

Results: Brainstem auditory evoked potentials were within normal limits in all three cases.
