A Comparative Study of Brainstem Auditory Evoked Responses in Patients of Type 2 Diabetes Mellitus and Healthy Matched Controls at Tertiary Care Hospital, Bikaner, Rajasthan India
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2018, Vol 6, Issue 4
Abstract
Diabetes Mellitus has been implicated as an independent causative factor of sensorineural hearing loss. The Brainstem auditory evoked responses (BAER) represent a useful, non invasive and simple procedure to detect both acoustic nerve and CNS damage. The study was conducted to compare Brainstem auditory evoked responses in patients of Type 2 diabetes mellitus with matched normal subjects. Effect of duration of diabetes on BAER and usefulness of this screening tool were also assessed. A Comparative Cross-sectional study was carried out to compare Brainstem auditory evoked responses in patients of type 2 Diabetes Mellitus (n=50) and matched healthy controls (n=50) at Department of Physiology in association with ENT Department at S.P. Medical College & P.B.M. hospital Bikaner, Rajasthan from June 2016 to May 2017 with Consecutive sampling technique. All BAER waves I to V & Interpeak latencies (I-III, III-V & III-V) of both ears showed statistically significant difference (p<0.05) among cases and controls except Interpeak latency of III-V of left ear. Cases had prolonged interpeak latencies which is an early sign of central neuropathy and can prove diagnostically important. Correlation coefficient among BAER Interpeak latencies among both right and left ears of cases showed only partial or weak correlation which depicts that interpeak latencies are not affected much by duration of disease. Therefore it is derived that BAER waves can act as a screening tool for central neuropathy.
