Sažetak
Some children with an idiopathic articulation disorder have poor phonemic discrimination abilities (PDA) which can be due to a central hearing disorder, although this has not been confirmed by neurophysiologic techniques to date. Literature suggests cortical localization of the disturbances, although the subcortical level is not excluded. Authors have used the auditory brainstem response (ABR) technique and tested 30 boys 6 to 7 years old with articulation disorders and poor PDA (group 1), and compared the ABR results with those obtained in a group of 30 children with articulation disorders but good PDA and 20 children with correct articulation. Statistical analysis found significant differences between group 1 and the other children because of prolonged latencies of waves III and V and interpeak latencies I-III and I-V compared with the other children. The average ABR in group 1 had the characteristics of the ABR of a child under the age of one, whose maturation of response has not fully developed. The authors concluded that poor PDA are not only the result of cortical dysfunction and that it is possible that the basic problem in these children is prolonged conduction time and too slow processing of auditory stimuli at the level of the lower part of the brainstem, which can be the reason of the dysfunction at the cortical level.
