Abstract
Background and objectives: Brainstem auditory evoked potentials (BAEPs) have widespread clinical utility . BAEP responses exhibit a normal variability due to various non-pathologic factors and age is one of the variables suggested to have considerable influence on normal BAEP responses. Aging changes in the auditory system may significantly influence the interpretation of the auditory brainstem responses in comparison with younger adults. Hence, the study was planned to evaluate the influence of age on absolute and interpeak latencies in healthy subjects in the age-group of 18-70 years. Methods: The test was conducted on 150 healthy adults in the age-group of 18-70 years (75 males and 75 females). BAEP latencies were compared in different age groups by one way ANOVA. Correlations of latencies with age were performed using Pearson correlation coefficient. P value 48 years of age. Conclusion: Age contributes to the normal variations in BAEP latencies. Acquisition of a normative data for different age-groups can improve the clinical utility of the test. The pattern of interpeak latency changes with age in the present study indicates a greater possibility of involvement of peripheral auditory functions in the elderly subjects.
