[Epidemiology of central auditory disorders in school-age children. Literature review].

UNLABELLED: Central auditory disorders (CSD) - this is a violation of the processing of sound stimuli, including speech, above the cochlear nuclei of the brain stem, which is mainly manifested by difficulties in speech recognition, especially in noisy environments. Children with this pathology are more likely to have behavioral problems, impaired auditory, linguistic and cognitive development, and especially difficulties with learning at school.

OBJECTIVE

To analyze the literature data on the epidemiology of central auditory disorders in school-age children.

MATERIAL AND

METHODS

As a result of an initial search in databases (PubMed, ClinicalTrials, SCOPUS, ResearchGate, eLibrary, CyberLeninka), 328 articles were found by keywords, after an initial and further detailed analysis, a description of 9 studies is included in the review.

RESULTS

The prevalence of CSD in school-age children varies from 0.2% to 43.3% (median 8.6±14.6%), depending on the research methods used and the criteria for diagnosis. Sophisticated variants of speech audiometry (speech intelligibility in noise, low-excess, dichotic tests) and non-speech tests evaluating frequency and time resolution are most often used as diagnostic methods.

CONCLUSION

In the future, it is necessary to conduct population-based studies of the epidemiology of central auditory disorders among Russian schoolchildren using a standardized diagnostic protocol and with a sufficient sample size.
