These tests are useful in assessing sensory system functions in adults. Pattern shift visual evoked potentials are helpful in diagnosing visual disturbances, optic neuritis, multiple sclerosis and lesions of the afferent visual system.
Brainstem Auditory Evoked Potentials are useful in patients with disturbance of balance, eighth cranial nerve disorders, cerebellopontine angle tumors, neurofibromas and central disorders associated with vertigo.
Somatosensory evoked Potentials assess peripheral nerve, spinal cord and brainstem function in disorders such as spinal cord trauma, demyelinating disease and myelopathy.
