“…The study concurred with authors like Ghugare et al 20 that BMI showed no significant correlation with BAER variables; but varied with others like observations of Subramaniam et al 35 who reported an increase in the absolute latencies of waves I, III, and V obese adults with non-significant difference between interpeak latencies; Gupta et al 36 reported prolongation of BAEP absolute latencies III and V and interpeak latencies I-III and I-V (for both ears) in obese patients and Solanki et al 27 in their study emphasized BMI as an important variable influencing BAEP records.…”

“…The variance of present study to the above studies may be attributed to duration and type of obesity. Gupta et al 36 attributed the alteration in myelination in obese persons resulting in altered transmission and delay in latencies resulting in the said changes. In the present study only 16% were overweight and 2% were obese, hence the variance in results due to small sample representation is likely.…”

Head size gender and BMI have found to have correlation with Brainstem Auditory Evoked Potentials (BAEPs) in some studies but other have expressed doubts. There is no common consensus. To add to the complexity, the range of normative values also vary. The present pilot study was done aiming to study effect of gender and anthropometric parameters on the variables of BAEPs in audiometrically normal young adults and collect normative values for further studies. This was an observational prospective, cross sectional, pilot study conducted among 100 medical students with 50 males and 50 females. The selected students fulfilled the inclusion and exclusion criteria and had given informed consent for the study. In the study RMS EMG EP MARK II machine was used to measure and record the absolute, interpeak and wave amplitudes. The data was collected and statistically analysed. The BAEP measurements from the subjects were compared with gender and anthropometric measurements. The age of students enrolled in subject ranged from 18â€“21 years. The difference between Left and Right ears Wave I, III and V, besides I-Ia and V-Va difference was found to be significant; while differences between male and female peak latencies of Wave III (left and right) and V (left and right) and Wave IV right ear, I-V IPL and V-Va of Right ear were found to be statistically significant. BMI did not show any statistically significant correlation with BAEPs. AEP results were definitely individual effected by gender, with latency duration more among males than females in most BAERs but were significant in few. The head circumference of a person appears to affect the BAER. BMI in the study was not significant with BAER variables.

“…[21] A study on brainstem auditory evoked potential (BAEP) in overweight and obese individuals indicating CNS conduction delays with brainstem as well as cerebral cortical. [22] BERA comprise five or more waveforms that are recorded within 10 ms of an acoustic stimulus. Wave I originates from peripheral portion of cranial nerve VIII (auditory nerve) near the cochlear nucleus.…”

Background:The Type II diabetes mellitus (DM) is characterized by hyperglycemia, as a result of damaged beta cell function, along with increase insulin resistance, either at receptor or at postreceptor levels. Neuropathies complications are the most common in diabetes, that's may lead to delayed evoked potentials in the central pathways. Aims and Objective: This study was undertaken to know the hearing status of the Type II diabetic patients and to delay development of its related complication like central neuropathy. Materials and Methods: This study evaluates central neuropathy by brainstem evoked response audiometry (BERA) in Type II DM patients. Results: We observed significant differences in BERA latencies between diabetic patients and healthy controls. There was significantly delayed Wave II, IV latency in left ear (at 80 dB) and Wave II latency in left ear, as well as Wave IV latency in right ear (at 90 dB) as compared to control. Diabetics patients with and without peripheral neuropathy there were absolute delayed latencies of Wave I, III, and V (80 dB). With relation to blood glucose, a significant difference in absolute latencies of Wave II (right ear at 90 dB), Wave IV (in right ear at 90 dB), Wave V (left ear at 80 dB), and interpeak latencies I-V (in right ear at 90 band). Conclusion: This study suggests that BERA is a simple, non-invasive procedure to detect early impairment of acoustic nerve, and central nervous system pathways, even in the absence of specific symptoms, if BERA is carried out in diabetic patients, involvement of central neuronal axis can be detected earlier.

Background: Sleep interruption and disturbance of circadian rhythm are inevitable phenomena among night shift workers. A very few evidence is available that describing effects of sleep disturbance and its effect on the visual pathway by measuring the visual evoke potential parameters. Aims and Objectives: To study the change in visual evoked potential (VEP) due to disturbance of circadian rhythm among rotating shift workers. Materials and Methods: This cross-sectional study was done on 80 security guards of 20-40 years of age working in Government Medical College and New Civil Hospital of Surat. They were divided into two groups comprising of 40 participants. Group 1 comprised of 40 security guards who did rotating night shift for more than 6 months and Group 2 include 40 security guards who did not perform any night shift duty for the past 2 years. VEP test was done, and results of both groups were compared with each other. Result: The result showed that there was statistically significant (P < 0.05) prolongation of P100 latency in rotating shift workers compared to day workers. The amplitude of P100 decreases in shift worker while comparing both the groups, but it was statistically insignificant (P > 0.05). Pearson correlation revealed, as the head circumference increases, latency of VEP increases, and amplitude decreases. Conclusion: Alteration in circadian rhythm affected the parameters of VEP in a negative way. In long-term, it may impair their general health. Furthermore, further study is required to support this conclusion.
