Abstract
Introduction: There is a high prevalence of auditory processing disorders in children diagnosed as specific language impairment (SLI). Speech-evoked auditory brainstem response (speech ABR) is used to represent neural activity generated at different levels along the auditory pathway. Study design: Case- control study. Aim: To assess the neural encoding of speech at the brainstem level in children with SLI using Speech ABR, to compare the Speech ABR results of SLI children with their normal peers and then to correlate the results of Speech ABR to results of the behavioral speech in noise test (SPIN). Subjects and methods: Sixty children of both genders were enrolled in this study and divided into 30 normal children and 30 children with SLI. Their age ranged from 3 to 7 years. All subjects were submitted to full history taking, otologic examination, basic audiological examination, Speech ABR, SPIN test, psycho-social evaluation (IQ testing) and language evaluation. Results: All SLI children showed statistically significant delayed latencies and diminished amplitudes of all waves in both ears, compared to their controls. In addition, SLI children had shallower V-A complex slope. There was a statistically significant difference between the SLI children and their control peers regarding the SPIN test. Also a decrease in the language test scores was noticed among the SLI children compared to their normal peers. Latency of Speech ABR waves decreased with increasing age of children under study. On the other hand, no significant correlation was present between waves’ amplitude and age. Wave V was the most common wave to correlate with the SPIN test, followed by wave F
