  7. Vestibular evoked myogenic potentials in multiple sclerosis patients. Versino M, Colnaghi S, Callieco R, Bergamaschi R, Romani A, Cosi V. Clin Neurophysiol 2002 Sep;113(9):1464-9 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%

  8. Clinical study of vestibular-evoked myogenic potentials and auditory brainstem responses in patients with brainstem lesions.Itoh A, et al. Acta Otolaryngol Suppl 2001;545:116-9 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

  9. Diagnostic value of prolonged latencies in the vestibular evoked myogenic potential.Murofushi T, Shimizu K, Takegoshi H, Cheng PW. Arch Otolaryngol Head Neck Surg 2001 Sep;127(9):1069-72 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.

  10. Diagnostic value of prolonged latencies in the vestibular evoked myogenic potential.Murofushi T, Shimizu K, Takegoshi H, Cheng PW. Arch Otolaryngol Head Neck Surg 2001 Sep;127(9):1069-72 VEMP were absent or decreased in 51% of patients with Meniere disease 39% with vestibular neuritis 77% with acoustic neuroma 25% with multiple sclerosis

  11. Diagnostic value of prolonged latencies in the vestibular evoked myogenic potential.Murofushi T, Shimizu K, Takegoshi H, Cheng PW. Arch Otolaryngol Head Neck Surg 2001 Sep;127(9):1069-72 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.
