Cortical Evoked Potentials in Children with Learning Disorder
Journal Title: Journal of Medical Science And clinical Research - Year 2015, Vol 3, Issue 4
Abstract
The purpose of the study was to investigate MLR and LLR response from children with LD. Auditory cortical potential were recorded in 30 subjects with LD (experimental group) and 30 age-gender matched children (control group) aged 10 -14 years with means age 11.2years. The responses were recorded using the click stimulus. MLR (Pa, Na) & P1, N1, P2, N2 latency and amplitude were analyzed. Result of study indicates that both the group had statistically significant difference in latency. Pa, Na , P1 and N1 amplitude had significant different between two test group. The present study finding reports that click evoked auditory late latency response is traceable in all children with LD and typically developing children. However, children with LD exhibited prolonged latency with reduced amplitude with inconsistent wave morphology responses. The present study, inferred that the abnormalities in processing from the thalamus, auditory cortical area results in altered auditory cortical recording. However further, research is required to use MLR, Long latency response as a tool that clinically differentiates between individuals with and without LD.
