Abstract:
Objective To investigate the characteristics of auditory brainstem response (ABR) in autistic children of 6 years or younger .Methods A total of 98 children with normal hearing and 22 autistic children were en‐rolled in this study .They were divided into 3 groups :1~2 years age group ,2< ~3 years age group ,and 3< ~6 years age group .The thresholds ,wave latencies and interpeak intervals of ABR were statistically analyzed .Results The ABR thresholds in normal hearing children (and autistic children) in 1~2 years age group ,2< ~3 years age group ,and 3< ~6 years age group were 15 .64 ± 5 .02 (17 .50 ± 5 .35) ,14 .73 ± 4 .85 (17 .81 ± 6 .58) ,and 15 .57 ± 5 .62 (17 .25 ± 6 .97) dB nHL ,respectively .There were no significantly statistical difference between the normal hearing children and autistic children (P>0 .05) .In 80 dB nHL click sound stimulus ,there was also no statistical difference in the values of peak latencies or interpeak intervals of ABR between normal hearing children and autistic children (P> 0 .05) ,whereas ,prolongation of peak latencies or interpeak intervals of ABR occurred in 36 .36%(25 .00% ears) autistic children .The ratio of prolongation of peak latencies of I ,III ,V waves and interpeak inter‐vals of I-III ,III-V ,I-V occurred in 4 .54% ,6 .82% ,13 .64% ,18 .18% ,6 .83% and 15 .91% ,respectively . Conclusion The ABR in some autistic children present abnormality and occur in various forms with the prolongation of interpeak intervals of I -III as the most common .
