Dr. D. Indumathi, Dr. I. J. V. Pradeep Vaiz, T

Abstract :

INTRODUCTION: Slow learners comprise upto 7% of the school going children in India. These children are associated with increased risk for psychopathological disorders. AIM:The present study was undertaken to examine the functional integrity of visual & auditory pathway in slow learners. A standard psychological & neurophysiological test, if done early will help to identify slow learners & prevent behavioral problems that result due to late diagnosis.METHODOLOGY: The subjects were selected from special education school. Psychological evaluation was done using Malin’s intelligence scale. Forty subjects (IQ:70–85) in the mean age group 10–15 yrs & forty age/sex matched control were selected. Electrophysiological evaluation of VEP & BAEP was done. RESULTS: VEP study shows significant prolongation of N75 and P100 latencies due to defect in magnocellular pathway & BAEP showed significant prolongation in I–III & I–V IPL due to delay in conduction of impulses in pontomedullary and midain auditory pathway in slow learners.
