Abstract

Background: Obesity is a chronic condition, affecting central and peripheral nervous system. Studies on cranial nerve conduction in obesity are scarce and unclear; therefore, we planned this study. The aim of this study was to evaluate optic and auditory nerve conductions in obesity.

Methods: It was a case-control study, with inclusion of 40 young males (20 obese and 20 controls) in age group of 18-30 years. We recorded pattern reversal visual evoked potential (PRVEP) and brainstem auditory evoked potential (BAEP). The PRVEP P100 latency and BAEP absolute and interpeak latencies were analyzed.

Results: In obese individuals, BAEP absolute latencies of wave V were significantly prolonged in both the ears and wave I in left ear. In addition, significant prolongation of interpeak latency III-V was observed in both the ears and I-V latency, in right ear among obese cases. A positive correlation was seen between body mass index and interpeak latency I-V. In PRVEP recordings, P100 latency did not show any significant difference in both the groups.

Conclusion: Therefore, we can conclude that obesity does not affect optic nerve conduction, but auditory nerve conduction is affected. BAEP I-V interpeak latency may be an indicator of subclinical auditory conduction defects in young obese males.
