Study of brainstem auditory evoked response in type 2 diabetes mellitus.

ABSTRACT

Background: Diabetes is a major cause of morbidity and among its complications neuropathies are the most common. Diabetes may alter both the central and peripheral nerve functions but the peripheral manifestations of diabetic neuropathy are more frequently discussed in the literature than the impairment of central nervous system. Objective: To study the Brainstem Auditory Evoked Response (BAER) in 30 type 2 diabetes mellitus patients and compared to age and sex matched 30 non diabetic group. Methods: 30 Type 2 diabetics and 30 age and sex matched control group were selected and subjected to BAER. Duration of latencies, interpeak latencies and amplitudes were recorded. Results: According to BAER report, Left side latencies III , both left and right IPL III – V , right side ampliude V decreased with p > 0.05 in type 2 DM compared to control group . Conclusion: The study showed bilateral changes in BAER report in type 2 DM. This indicates use of evoked potentials like BAER helps in evaluating central neuropathy in patients with type2 DM. Earlier diagnosis of central neuropathy is recommended for proper management.
