Auditory Testing can Identify Kids for Autism Screening

A strong link between auditory dysfunction and autism has been identified, suggesting that hearing issues identified at birth can be a clue to monitor the child for autism.

A new and noninvasive hearing test was found to assist with early detection and diagnosis of autism spectrum disorders, revealed research published in the Journal of the American Osteopathic Association.

The authors note a strong //connection between auditory dysfunction and autism, suggesting that hearing issues identified at birth can be a clue to monitor the child for autism. Uncovering hearing issues would also improve outcomes for all children because the finding would trigger early interventions.

Autism Causes, Symptoms, Diagnosis, Treatment, Prognosis
Autism is a neurodevelopmental disorder typically characterized by impaired social and communication skills combined with repetitive movements.

‘Testing at birth for autism could allow for optimized early interventions that improve outcomes. ’

"We know the vast majority of people with autism have some type of hearing problem connected to abnormalities in the brain," says Randy Kulesza, Jr., PhD, Professor of Anatomy at Lake Erie College of Osteopathic Medicine. "That means these issues will be present and detectable at birth."

Kulesza acknowledges that while the vast majority of people with autism have hearing issues, not everyone with hearing issues has autism. Still, he says early detection would benefit both groups.

"Especially early in life, the brain is very plastic, meaning the right early interventions can literally train out those deficits. The person might not be perfectly neuro-typical but such interventions can improve function," says Kulesza.

Quiz on Autism
Autism spectrum disorder is a complex genetic disorder that impairs social, behavioral, and communication functions in humans. Autistic people may act, communicate, interact, and learn differently than most other people. ASD usually begins in childhood and can last for the rest of a person's life, though symptoms may improve over time

He also notes that hearing is critical to speech-language development, which in turn, also affects social-emotional development. By optimizing auditory function, the person's quality of life can be profoundly better.

Currently, newborn babies have their hearing tested. However, Kulesza says those tests merely assess whether the child can hear on a pass/fail basis. He says stapedial reflex testing provides much more information about the types of dysfunction that may be present.

Microbial Activity in the Mouth May Help Identify Autism in Children
Bacteria living in a child's mouth can serve as a potential tool to identify autism spectrum disorder (ASD) in children.

Stapedial reflex testing, also known as acoustic reflex testing, measures pressure changes in the middle ear in response to sounds. It assesses a person's sensitivity and response times to a wide range of frequencies.

"Often people with autism suffer from hypersensitivity, meaning even relatively quiet sounds can feel like overwhelming noise," says Kulesza. "If parents and physicians understand that from the start, they can work to acclimate the child's sensitivity and make his or her experience of the world much less intense and frightening."

While there are clear connections between autism spectrum disorders and auditory dysfunction, Kulesza says more research is needed to understand how best to employ interventions for those who have the hearing issues.

One serious concern Kulesza shares is causing unnecessary stress to parents. He emphasizes that stapedial reflex testing should not be presented as a diagnostic tool for autism. Rather, parents should understand that testing positive for auditory dysfunction allows for tailored early intervention that will maximize their child's potential.
