Background: There is a high prevalence of auditory processing disorders in children diagnosed with learning disability; the deficits identified determine the appropriate management. So it is important to identify any auditory processing disorders in this population for optimum interventions so as not to compromise their learning process.Objective: To assess central auditory processing functions in children with learning disability through electrophysiological and behavioral testing, and to correlate between electrophysiological and behavioral test battery in learning disabled children.Subjects And Methods: The present study comprised 60 normal hearing children of both genders. Cases included 30 learning disabled children and the controls included 30 healthy children. Each group was further subdivided into three subgroups according to the age: Subgroup a: age ranging from 6-8 years, Subgroup b: age ranging > 8-10 years, Subgroup c: age ranging >10-12 years. All subjects were submitted to full history taking, otologic examination, basic audiological evaluation, central auditory processing testing and speech-ABR testing.Results: This study showed that the prevalence of CAPD in children with LD was 80 %. There were a statistically significant difference between the cases and controls regarding all the central tests except the LPFT and the youngest subgroup regarding the SPIN test. All LD children showed statistically significant delayed latencies of waves V, A and F in both ears in all tested subgroups, compared to their controls. Concerning the amplitude of the waves, there was statistically significant diminished amplitude of wave F in all tested subgroups in both ears when compared to their controls. In addition to a statistically significant decreased amplitudes of waves D and E in 6-8 years subgroup and waves C and D in 8-10 years subgroup. Wave F was the most common wave to correlate with the behavioral central tests especially SPIN, DDT and PPS tests, followed by wave E.Conclusion: The high prevalence of auditory processing disorders in children diagnosed with learning disability suggests that central auditory processing disorder can be an underlying etiology for learning disability. Speech evoked response parameters were highly correlated with most of psychophysical tests in LD children, so it is a valuable tool in testing young children who are too young to perform the psychophysical test battery.
