BACKGROUND: Brainstem involvement (BSI) has been reported as a major predictive factor for future disability in Multiple Sclerosis (MS).
AIMS/OBJECTIVES: To evaluate whether Cervical Vestibular Evoked Myogenic Potentials (cVEMPs) and Video Head Impulse Test (vHIT) can be used to detect demyelinating lesions in vestibular pathways in MS.
MATERIAL AND METHODS: Fifty three people with MS and 40 controls were evaluated with Dizziness Handicap Inventory (DHI), vHIT and cVEMP.
RESULTS: The median value of DHI in MS group was significantly higher than controls (p<.001). According to vHIT results, while the results of horizontal canal vestibulo-ocular reflex gain in group with brain stem involvement (gBSI (+)) were significantly different from both controls and group without brain stem involvement (gBSI (-)) (p= .036 and .024, respectively), results of gBSI (-) were similar with controls (p= .858). When cVEMP results were examined, mean P1 wave latency in gBSI (+) was significantly longer than controls (p= .002), but difference between gBSI (-) and controls and gBSI (+) was not statistically significant (p= .104 and .279, respectively).
CONCLUSIONS AND SIGNIFICANCE: vHIT and cVEMP can be used in diagnosis and follow-up of people with MS without demyelinating brainstem lesions on MRI.
