The Study Of Age And Sex Related Changes In The Brainstem Auditory Evoked Potential

摘要

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.
