Abstract

Objective Specific language impairment (SLI) is a developmental disorder when a child has difficulty in producing or understanding spoken language for no apparent reason. The study attempts to carry out an in-depth review of electrphysiological findings in individuals with SLI. Study design Review of literature was carried out to review and critical analyse the electrophysiological findings in individuals with SLI. Results The results of the review showed contradicting results in this population. Some studies have reported a statistically significant difference in morphology, latency and amplitude of auditory evoked potentials (AEPs) between the children with SLI and the control group. This suggests that children with SLI may have auditory processing problems at the level of brainstem, sub-cortical and cortical areas. While few other studies showed no abnormalities in auditory processing in children with SLI, with intact waveform morphology, latency and amplitude of AEPs. Conclusion AEPs were observed to be more variable lacking uniformity because of the heterogeneous nature of SLI. However, further studies need to be conducted to evaluate the auditory processing abilities using auditory evoked potentials in children with SLI.
