ABSTRACT
Age is one of the important factors in the clinical interpretation of Brainstem Auditory Evoked Potential (BAEP) waveform components and it can change the value of peak latencies and interpeak latencies among different age groups. The present study aims to measure all BAEP waveform peak latencies and interpeak latencies and to evaluate changes in standard deviation in 77 normal adult male subjects in age groups of 10-20, 20-30, 30-40, 40-50 and 50-60 years. The results obtained in this study show that as the age rises from 10 to 60 years, so do the values in peak latencies and interpeak latencies of all BAEP waveforms recorded from ipsilateral and contralateral ears. For example, the changes in value of wave I that belong to age group of 10-20 years come out to be 1.53±0.005 (p<0.001) while changes in the same wave for the age group of 50-60 years was 1.83±0.035 (p<0.001). I-III interpeak latency values from younger to older age groups vary from 1.96±0.014 (p<0.001) to 2.08±0.148 (p<0.005), respectively. The results in this study show that the variation related to waves I, III and V peak latencies of younger age groups in both ears is smaller than older and that changes attributed to ipsilateral ears are slightly smaller than values of contralateral ears in all age groups. While I-III, III-V and I-V interpeak latencies in all age groups had an increased value.
