Subjective Interpretation of Caloric Induced Vertigo in Asymptomatic Diabetic Versus Normal Volunteers:

Abstract

objectives: to evaluate if there is variability in subjective perception of vertigo in diabetic patients in comparison to non-diabetic subjects. Methods: 28 patients with diabetes type 2 and 28 normal volunteers participated in the present study. Monothermal cool caloric test used to induce vertigo and visual analog scale (VAS) used to quantify the intensity the perceived caloric induced vertigo. Results: there was no significant difference between both groups in all study variables. There was a significant difference in VAS scores between both ears in diabetic group patients. Conclusion: there is abnormal vestibular performance in diabetic patients even in the presence of normal vestibular laboratory functions.
