The aim of this work was to perform an audiological evaluation on a group of children with autistic features and to correlate the results with the intelligent quotient, communication skills, and sensory integration function of these children.

Study design

Descriptive cross-sectional study.

Patients and methods

The study was carried out on 25 Egyptian children with autistic features and 25 age-matched and sex-matched typically developing children. All the children’s age ranged from 4 to 9 years. All the children were subjected to the following: history taking, basic audiological evaluation, transient evoked otoacoustic emissions, N100, and P300. The children were also subjected to communication assessment, sensory integration dysfunction questionnaire, psychometric evaluation, and the Childhood Autism Rating Scale. The results obtained from the two groups were then compared. In addition, correlation studies were carried out for all the results obtained.


Autistic children presented with normal hearing sensitivities and cochlear function, and delayed N100 and P300 latencies and small P300 amplitudes compared with the control group. There was a significant negative correlation between N100 latency and verbal and nonverbal communication abilities. In addition, there was a significant correlation between P300 latency and amplitude and each of the following: intelligent quotient, the Childhood Autism Rating Scale, and dynamic assessment of verbal and nonverbal communication. The auditory and visual modalities of the sensory integration dysfunction score correlated positively with P300 latency but not amplitude.


The auditory deficits in autism involve controlled attention processes, speed of perceptual classification, and allocation of attention. N100 is a correlate of the level of communication and language development rather than a marker of autism. P300 abnormalities affect verbal and nonverbal communication, mental development, autistic features, and sensory integration function in autism and may be used as a tool to assess the prognosis of autism.
