A follow-up study of effect of type 2 diabetes mellitus on the cervical vestibular evoked myogenic potential

Abstract

Abstract Background Type 2 diabetes mellitus is a systemic disorder affecting glucose metabolism. It is known to impact neuronal function and lead to generalized neuropathy. This study aims to explore its effects on cervical vestibular evoked myogenic potentials, even after blood sugar levels are managed with appropriate treatment. Methods A pre-post follow-up study was conducted with 114 participants diagnosed with type 2 diabetes mellitus. Initial evaluations were performed before starting diabetes treatment, and a second evaluation occurred 3 months later, after blood sugar levels had been managed. A control group was established to compare the findings from the pre-treatment and post-treatment assessments of the study group. Results A significant decrease in sugar levels was observed after treatment. However, there was no notable difference between the pre-treatment and post-treatment indices of cervical vestibular evoked myogenic potentials in participants with diabetes mellitus. Additionally, participants consistently showed poorer results compared to the control group, both before and after treatment. Conclusion It can be inferred that elevated blood sugar levels have a lasting effect on the indices of cervical vestibular evoked myogenic potentials.
