Abstract
This study aimed to compare cervical vestibular-evoked myogenic potentials (cVEMP), ocular vestibular-evoked myogenic potentials (oVEMP) and video head impulse test (vHIT) results between patients with type 2 diabetes mellitus (DM) or diabetic polyneuropathy (DPN) and healthy controls to determine vestibular end-organ pathologies. The participants in the present study consisted of three groups: the type 2 DM group (n = 33 patients), the DPN group (n = 33 patients), and the age- and sex-matched control group (n = 35). Cervical VEMP, oVEMP and vHIT were performed for each participant in the study and test results were compared between the groups. Peak-to-peak amplitudes of cVEMP (p13-n21) and oVEMP (n10-p15) were significantly lower in the DM and DPN groups than the control group. The values of vHIT were not statistically different between the groups. To our knowledge, the present study is the first report investigating oVEMP and cVEMP responses combined with vHIT findings in patients with DM and DPN. Vestibular end-organ pathologies can be determined via clinical vestibular diagnostic tools in spite of prominent vestibular symptoms in patients with type 2 DM as well as patients with DPN.
