/Autism Spectrum Disorder(ASD)Hearing Abnormalities Study
Co morbidity rates of hearing loss in children with autism spectrum disorder are high and
 increasing.

 Investigators are aiming to:

 1. evaluate peripheral auditory and brain stem auditory function in children with autism
 spectrum disorder.

 2. compare communication capabilities in autistic children having hearing abnormalities and
 autistic children with normal hearing.
Full audiological evaluation is carried out to all participants including:

 -  pure tone and speech audiometry.

 -  Tympanometry and acoustic reflex threshold evaluation.

 -  Threshold auditory brain stem response for threshold determination in non co operative
 children not respond to pure tone,speech audiometry.

 -  Auditory brain stem response for neuro-otologic diagnosis.

 -  Transient evoked otoacoustic emissions in children proved to have normal hearing to
 detect minimal cochlear affection .

 -  Transient evoked otoacoustic emissions with contralateral masking. Communication
 evaluation is carried out to all participants using arabic language test(kotby et
 al,1995).

 Investigators use childhood autism rating scale for (CARS) for diagnosis of autism spectrum
 disorder.
Inclusion Criteria:

 -  Children aged 3-12 years diagnosed to have mild to moderate autism spectrum disorder
 diagnosed by childhood autism spectrum disorder(CARS 35% or less)

 Exclusion Criteria:

 -  children with otitis media with effusion.

 -  Associated neurological deficit .
