Developmental profiles for the brainstem auditory evoked potential

Abstract Brainstem auditory evoked potentials (BAEP's) were recorded from 641 subjects in eleven age groups ranging from birth through adulthood, including three levels of prematurity, in order to establish an age-specific normative data base. The amplitude and latency values for waves 1–6, interwave differences for 3-1, 5-3, 5-1 and the amplitude ratios for 5/3 and 5/1 were then converted to percentile scores to permit construction of age-related BAEP profile report forms. Visual inspection of the printed output reveals the proportion of subjects falling above and below a given individual across all BAEP measures. This simple format is useful for general screening purposes as well as plotting maturational changes in healthy or high risk infants.
