Abstract The objective of the study was to assess whether a relationship exists between the auditory brain stem response (ABR) results and diabetes mellitus with and without complications. In the clinical and audiometry laboratory settings, diabetic patients with and without complications (retinopathy and/or nephropathy) were examined using ABR testing, and the results were interpreted for their applicability in clinical practice. Fifty-nine patients with diabetic retinopathy or nephropathy (study group) and 20 diabetic patients without any known diabetic complication (control group) were assessed with audiometry and ABR testing. ABR revealed that the absolute latencies and interwave intervals of the waves I through V were prolonged significantly in the study group when compared to the control group. The amplitudes of waves I through V were diminished in the study group when compared to the control group, but a statistical significance was present only for wave V amplitude. Quantitative (wave I to wave V amplitude ratio) and qualitative analyses of the ABR waves showed abnormal waveforms in the study and control groups by 55.2 and 27.6\%, respectively. There is a brain stem neuropathy in diabetes mellitus which can be assessed with ABR testing. The likelihood of encountering a diabetic complication increases as the ABR results become abnormal.
