Learning disability assessed through audiologic and physiologic measures: a case study.
This report describes a child with central auditory dysfunction. Audiologic tests (Willeford Battery and Staggered Spondaic Word Test) indicate a brain-stem dysfunction but normal cortical functioning. Electrophysiologic tests corroborated these results. Brain-stem auditory-evoked responses (BAERs) indicated an absent contralateral peak III bilaterally when stimulating each ear separately. This is the first reported case where brain-stem dysfunction on audiologic tests were associated with specific electrophysiologic changes in the BAER.
