New study reveals that there may be a connection between hearing and autism.

Many children with autism have difficulties interacting and communicating with others. Due to these social, communication and behavioral challenges, it is important that parents are aware of how to properly care for their children – especially when they are young. However, it may be a while before parents discover that their child has autism. New research suggests that a connection between hearing and autism might be able to identify which children are at risk for the disorder.

Hearing and Autism: Inner-Ear Deficiency

Autism Spectrum Disorder (ASD) is classified as a neurodevelopmental disorder, in which it is difficult for one to interact socially or communicate with others (verbally and non-verbally). Some even display restrictive or repetitive behavior. The behavioral signs of autism are not the same for every person. Some children with autism are able to interact with people better than other kids can.

Diagnosis is often troublesome. Most parents identify the disorder after their child is two. However, since the disorder’s symptoms are behavioral, some children will develop normally—and then start to show signs after they turn four.

The new research from the University of Rochester Medical Center has discovered an inner-ear deficiency in children with autism. It may be why some children have trouble recognizing speech. The researchers hope that doctors can use their findings to start identifying the deficiency in younger children, in order to inform parents that their child is at risk.

“This study identifies a simple, safe, and non-invasive method to screen young children for hearing deficits that are associated with Autism,” says Anne Luebuke, Ph.D., co-author of the study, and associate professor of the University of Rochester Medical Center Departments of Biomedical Engineering and Neuroscience.

The hearing test they used measures optoacoustic emissions by using a miniature microphone and speakers to listen to the inside of the ear. Certain sounds are made inside the ear in response to the sounds heard by the individual. When the inner workings of the ear do not respond to certain sounds, then it is determined that this function is impaired. Of the 17 children who were tested, half where already diagnosed with ASD. Those children had difficulties hearing certain frequencies.

With this new research into hearing and autism, Dr. Luebuke is optimistic, stating “This technique may provide clinicians a new window into the disorder and enable us to intervene earlier and help achieve optimal outcomes.”
