Abstract:

Objective To establish a range of clinical reference values for each component of P1, N1, P2, N2, and P3 in auditory event related potentials (AERPs) in normal children aged 6-17 years, and to provide an assessment of cognitive impairments caused by clinically relevant diseases in children. Methods Healthy children with normal hearing who visited the Diagnosis and Treatment Center for Hearing Impairment and Vertigo between January 2024 and January 2025 were selected as study participants. AERPs were recorded using the auditory Oddball paradigm. Differences in AERP waveform components between both ears were compared, and normative values for the latency and amplitude of each AERP component were established. Results A total of 28 healthy children (56 ears) with normal hearing aged 6 to 17 years were included, with an average age of (8.75±2.40) years, including 15 boys (30 ears) and 13 girls (26 ears). The normal latency of each wave component of AERP in children is as follows: P1 (56.00±13.11) ms, N1 (106.36±15.26) ms, P2 (183.29±26.77) ms, N2 (229.21±26.28) ms and P3 (329.89±22.32) ms. The 95% confidence intervals (CI) are: P1 (30.29-81.71) ms, N1 (76.44-136.27) ms, P2 (130.82-235.75) ms, N2 (177.71-280.72) ms, and P3 (286.14-373.64) ms. The amplitude values are as follows: P1 [6.91 (4.91 - 10.92)] μV, P1-N1 [9.26 (4.82 - 14.79)] μV, N1-P2 [9.90 (5.60-14.25)] μV, P2-N2 [6.21 (4.40-9.94)] μV and N2-P3 [10.68 (5.95-15.81)] μV; 95% confidence intervals are: P1 (5.37-10.43) μV, P1-N1 (6.06-11.79) μV, N1-P2 (6.96-12.98) μV, P2-N2 (5.20-8.80) μV and N2-P3 (9.15-14.93) μV. Conclusions This study initially established the normal reference values of each component of AERPs for children aged 6 to 17, which is helpful in providing data support for the clinical assessment of cognitive function impairment in children.
