Abstract :

Background:

Diabetes mellitus(DM) is a metabolic disease that produces vascular and neurological complications. In type 2 diabetes mellitus, resistance to insulin is accompanied by an insufficient recompense in the secretion of insulin. Due to metabolic dysregulation many pathophysiological changes are seen. Brainstem auditory evoked potentials(BAEP)are the potentials recorded from the ear and vertex in response to a ief auditory stimulation to assess the conduction through auditory pathway up to the midain and it produces wave I to wave V. The eighth cranial nerve and ain functions are impaired in type II Diabetic patients. Aim&Objective: To study the Brainstem auditory evoked potential in type II diabetic patients and to compare it with normal individuals. Materials and Methods: In this study 30 type 2 diabetes mellitus subjects were selected from department of diabetology OPD, Stanley medical college and Control group of 30 were selected from master health check up.BERA recording was done in Neurophysiology laboratory, Department of physiology, Stanley medical College using POLYRITE MEDICAID –Neuroperfect plus.Results:There was a significant increase in latencies of waves I,III,V and interpeak latencies of waves I–V&III–V of diabetics when compared with controls (p < 0.01).Conclusion:BERA is a simple and non invasive procedure to detect early impairment of acoustic nerve damage and CNS pathways.Hence it can be used even in the absence of specific symptoms.This study suggests that if BERA is carried out in diabetics,involvement of central neuronal axis can be detected earlier.
