STUDY OF BRAINSTEM EVOKED AUDITORY RESPONSE IN TYPE 2 DIABETICS WITH NORMALAND ELEVATED BODY MASS INDEX

Abstract

Background: Diabetes mellitus is a metabolic syndrome affecting many organs including the heart, kidneys, eyes and nerves Aim: The study aims to understand the changes in brain stem evoked auditory response(BERA) in type 2 diabetics with normal and elevated Body mass index. Materials And Methods: 60 individuals diagnosed with type 2 diabetes belonging to age group 30 - 50 years having normal and elevated BMI (Body Mass Index) were studied. Their Brainstem evoked auditory response was recorded and results were studied with the help of unpaired t test. The brainstem evoked auditory response(BERA) wave latencies I, II, III, IV, V and interpeak latencies I-III, III-V, I-V were recorded individually for left and right ear. Result: Signicant increase in latencies of waves I, III, V and interpeak latencies I-III, III-V, I-V were observed in diabetics with elevated BMI when compared with normal BMI. There was a positive association seen between BMI and wave latencies I, III,V and interpeak latencies I-III, III-V, I-Vwere also observed. Conclusion: The study shows that type2 diabetic patients with elevated BMI can have subclinical hearing loss and impaired brainstem evoked auditory response. BERA is a simple non-invasive tool in early diagnosis. So management of diabetes along with maintaining ideal Body mass index will help in preventing early sensory neural hearing loss.
