70 MS patients, retrospectively evaluated for
possible occurrence of past and current
brainstem and/or cerebellar symptoms or signs.
  • RESULTS
  • VEMPs were abnormal in 31,
  • BAEPs in 38
  • SVV in 21
  • Saccadic eye movements showed a possible
    brainstem dysfunction in 44.4

Clinical study of vestibular-evoked myogenic
potentials and auditory brainstem responses in
patients with brainstem lesions.Itoh A, et al.
Acta Otolaryngol Suppl 2001545116-9
Brainstem lesions using MRI 4 multiple sclerosis,
3 brainstem hemorrhage, 1 pontomedullary
infarction, 4 Wallenberg's syndrome
Middle brainstem lesions of the pons ABR and
VEMP abnormal. Medulla ABR normal VEMP
abnormal. Middle-to-lower brainstem lesions
a disappearance of VEMP, delay of PN wave,
increase in PN interpeak latency decrease in
PN amplitude on the affected side

Clinical records of 134 patients (61 men and 73
women, aged 20-75 years) Diagnoses Meniere
disease in 43 patients, Acoustic neuroma in 62
patients, Vestibular neuritis in 23
patients,Multiple sclerosis in 6 patients.

VEMP were absent or decreased in 51 of
patients with Meniere disease 39 with
vestibular neuritis 77 with acoustic
neuroma 25 with multiple sclerosis

vestibular evoked myogenic potential.Murofushi

Concerning latency, Meniere disease or vestibular
neuritis no latency prolongation. 4 patients
with acoustic neuroma showed prolonged p13
all had large tumors. All patients with multiple
sclerosis showed prolonged p13. CONCLUSIONS
Prolonged latencies of the VEMP suggest lesions
in the retrolabyrinthine, especially in the
vestibulospinal tract.
