Deaf children with autism spectrum disorders.

Epidemiological studies investigating the prevalence of autism have increased in recent years, within the United States and abroad. However, statistics as to how many of those children may also have a comorbid hearing loss is lacking. The prevalence of school-administrator reported diagnosis of autism spectrum disorders (clinical diagnosis [DSM-IV] and/or IDEA classification) among children with hearing loss in the US was estimated from the 2009–2010 Annual Survey of Deaf and Hard of Hearing Children and Youth conducted by the Gallaudet Research Institute.
