Auditory evoked potential responses were recorded in 150 normal healthy subjects of different age groups (G1 = 15-29 years, G2 = 30-45 years, G3 = 46 years onwards), with a matched number of males and females in each group. These potentials were recorded by using EEG electrodes on an RMS EMG, EP MARC II (PC-based) machine. The data was statistically compared between the different age groups and between the males and females and regression analysis was done. Absolute latencies of the waves III, IV and V and the interpeak latency of the waves, I-III and I-V showed significant increase with age, thus suggesting degenerative changes in the auditory pathway and synaptic delay. There were significantly increased values of the latencies of the waves III, IV and V and interpeak latencies of the waves, I-III, I-V and III-V in males as compared to the females. Thus, age and sex have an effect on latency and interpeak latency in Brainstem auditory evoked potentials.
