Brain-stem auditory evoked response: normative values in children
1Dept. of Child Psychiatry, Laval University, Beauport, Que., Canada.
Insights
This study presents normative brain-stem auditory evoked response (BAER) values for school-aged children (4-14 years). Findings reveal significant age and sex influences on specific BAER components, informing normative data development.
Area of Science:
- Neuroscience
- Audiology
- Developmental Psychology
Background:
- Brain-stem auditory evoked response (BAER) is a key electrophysiological measure for assessing auditory pathway function.
- Establishing normative data is crucial for interpreting BAER results in pediatric populations.
- Previous studies have indicated potential age and sex differences in BAER, but comprehensive normative data across a wide age range is needed.
Purpose of the Study:
- To establish normative values for brain-stem auditory evoked response (BAER) in a large sample of typically developing school-aged children.
- To investigate the influence of age and sex on various BAER components within this age group.
- To develop age- and sex-adjusted normative data for improved diagnostic accuracy.
Main Methods:
- A large cohort of 174 normal school-aged children (4-14 years) underwent BAER testing.
- Data analysis focused on identifying significant effects of age and sex on specific BAER waveform components.
- Normative values were computed, accounting for identified age and sex influences.
Main Results:
- Significant influences of sex were observed on certain BAER components.
- Significant influences of age were identified on other BAER components.
- Normative values were calculated and adjusted based on these age and sex effects.
Conclusions:
- Age and sex are significant factors influencing brain-stem auditory evoked response (BAER) measures in school-aged children.
- The derived normative values, adjusted for age and sex, provide a more accurate reference for clinical audiological assessment.
- These findings contribute to a better understanding of auditory development and maturation during childhood.
Abstract:
Normative values of brain-stem auditory evoked response (BAER) derived from a large (N = 174) normal school age sample are presented. In our 4-14 years of age sample we found a significant influence of sex on some BAER components, and a significant influence of age on others. The norms have been computed according to these influences. Particular aspects of the influence of age and sex are also discussed.
