Deaf Autism: Understanding The Connection Between The Two

Autism spectrum disorder (ASD), is a neurodevelopmental condition characterized by difficulties with social interaction, communication, and repetitive behaviors. Symptoms of autism can manifest differently in each individual, and each person with autism has unique strengths and challenges.

Deafness refers to a hearing loss or impairment that affects an individual’s ability to hear sounds. Deafness can range from mild to severe and can be present from birth or acquired later in life. Genetic factors, certain medical conditions, or exposure to loud noises can cause deafness. Hearing loss can impact an individual’s ability to understand speech, communicate effectively, and interact socially. 

Sometimes the two diagnoses can overlap, this is known as deaf autism. Flywheel Centers, experts on working with children with autism explain more here.

The Complex Relationship Between Autism and Hearing Loss

Autism and hearing loss are two distinct conditions, however, there is a significant relationship between the two. Understanding the connection is essential for providing support and interventions for people with autism who are deaf. 

Studies show that there is a higher co-occurrence of autism and deafness compared to deafness in the general population. Research has found that children with profound hearing loss were more likely to have a comorbid diagnosis of autism compared to those with milder forms of hearing loss. This suggests that the severity of hearing loss may contribute to the likelihood of autism being present alongside deafness. 

The exact causes of the relationship between autism and deafness are not yet fully understood and require further investigation. However, there are several theories, two of which are discussed below:

• Sensory processing differences that are common in children with autism may also affect their ability to process their auditory information. This could lead to difficulties in hearing and understanding speech, especially in noisy environments.
• There may be genetic factors that contribute to both autism and deafness. Studies have found that genetic mutations are more common in individuals with both of these conditions. 

Signs and Symptoms of Deafness and Autism

Deafness and autism spectrum disorders often have overlapping symptoms. Below we present some more information on what to look out for if you suspect someone might need help with a second diagnosis.

Identifying Deafness in Autistic Children 

It can be confusing to be able to tell if an autistic individual is deaf, as the symptoms of hearing loss are so similar to common signs of autism. It is important to look out for certain signs and to discuss them with a healthcare professional to ensure that hearing issues in autistic individuals are not overlooked. Some signs include:

Communication Symptoms 

• Delays in speech 
• Constant mispronunciation of words 
• No reaction when being spoken to

Behavioral Symptoms

• General behavioral problems at home and in school
• Not reacting to noises or sounds
• Using entertainment or devices on the highest volume 

While these signs may truly be connected solely to the individual’s autistic tendencies, it may be worthwhile to consider hearing loss as an issue as well. 

Indicators of Autism in Deaf Individuals

It is important to recognize the signs and symptoms of autism in deaf individuals, so they can receive the appropriate support and interventions. They may have difficulties with communication and social interaction.

Communication Difficulties

One of the most significant signs of autism in a deaf individual is difficulty with communication. These communication challenges can vary greatly among individuals, but may include the following:

• Challenges in developing and using language (in sign form as well)
• Delays in language acquisition
• Struggle with expressive and receptive communication 
• Difficulty following a conversation 
• Challenges understanding non-literal language

Social Difficulties

Deaf individuals with autism face a unique set of challenges when it comes to social interactions. Some aspects they may find difficult include:

• Making and maintaining eye contact
• Interpreting non-verbal communication
• Initiating and carrying a conversation
• Understanding social cues

These challenges can impact the individual’s ability to form relationships and can cause them to feel isolated and alone. 

Can Hearing Loss Look Like Autism?

Often, behaviors of autism and behaviors associated with hearing impairment can appear similar. This can make it hard to see whether you are looking at autism or hearing loss and there have been rare cases of hearing loss misdiagnosed as autism. These behaviors can be highlighted when they interact with others.

Behaviors in autism that mimic hearing loss include:

• Lack of normal eye contact: Avoiding eye contact is a common characteristic of autism. Children with hearing problems might not make eye contact if they don’t realize you are addressing them or trying to catch their attention.

• Echolalia: Children who are hard of hearing or deaf may repeat words to try to understand them and children with autism may also repeat words due to their behavioral patterns.  

• Delayed social skills: Children with autism usually have many social difficulties and children with hearing impairments tend to have trouble communicating as well.
• Delayed Language: Due to their hearing issues, children who are hard of hearing or deaf have difficulty reproducing sounds. Children with autism also have a hard time with verbal and non-verbal language development.

Challenges in Diagnosis

Diagnosing autism in deaf individuals presents unique challenges for clinicians and healthcare specialists. The cross-over between autism and deafness can complicate the diagnostic process and potentially lead to misdiagnosis or a missed diagnosis. Two major challenges in diagnosing autism in individuals who are deaf or have hearing loss are diagnostic overshadowing and the lack of validated assessment measures.

• Diagnostic Overshadowing 

Diagnostic overshadowing occurs when the presence of one disability, like deafness, masks the identification of another co-occurring condition, such as autism. The communication and behavioral difficulties that come along with deafness may overshadow the communication and behavioral challenges associated with autism, making it easy to misdiagnose a patient. 

All healthcare professionals and clinicians need to assess both hearing-related issues and the potential presence of autism. 

• Lack of Validated Assessment Measures

The lack of validated assessment measures brings forth yet another difficulty in diagnosing autism in individuals with hearing issues. Many traditional screening processes and diagnostic tools have demonstrated poor sensitivity specifically when used with deaf or hard-of-hearing individuals. 

Efforts are being made to develop and advance assessment measures to improve the diagnostic process for hard-of-hearing individuals who are suspected of having autism. 

Promoting Communication in Deaf Autistic Children

Due to their co-occurring conditions, individuals with autism and deafness may face unique challenges in expressing themselves and understanding others. It is crucial to adopt some techniques that consider their specific communication needs. Below are some of the strategies:

• Visual Supports: Visual aids such as visual schedules, visual cues, and social stories can be used to enhance understanding and communication.
• Communication Systems: Alternative communication systems like sign language, augmentative and alternative communication (AAC) devices, or picture exchange communication systems (PECS) can all facilitate communication for non-verbal or minimally verbal individuals.
• Positive Reinforcement: Positively reinforcing desired behaviors can encourage the development of communication skills. 

Role of Family and Caregivers in Communication

Family and Caregivers play an important role in facilitating communication for children with autism and deafness. They can help in several ways. 

• Supportive Environment: Creating a supportive environment is crucial in promoting the inclusiveness of children with autism and deafness. This can be achieved by:
• Communication aids: As mentioned above, implementing visual supports and alternative communication systems can create a more inclusive environment.
• Sensory considerations: Creating a sensory-friendly space, helps individuals with autism and deafness manage sensory overload and promotes comfort and engagement. One can do so by ensuring the lighting, temperature, and sound level are all comfortable for the individual. 
• Advocacy and Awareness: Parents and caregivers must advocate for their children with autism and deafness. By speaking out for their rights and raising awareness about their challenges and strengths, we can create a more inclusive society. Raising awareness can include the following:
• Collaboration: Encouraging collaboration among professionals, organizations, and communities can lead to the development of comprehensive interventions and services.
• Empowerment: Parents and caregivers can empower their children with autism and deafness to express their needs, make decisions, and be their own advocates. This empowerment fosters independence and ensures their voices are heard.

Educational Approaches and Resources for Autism and Deafness

The difficulties posed by having both autism and deafness may require a uniquely tailored educational approach. Below we have detailed some ideas that may be effective. 

Individualized Education Plans: (IEPs) are critical for students with autism and deafness. An IEP works well for children with autism and deafness by:

• Outlining specific goals, accommodations, and modifications to support their individualized learning abilities.
• It is developed collaboratively by the parents and educators to tailor it to the needs of each child. 
• Identifying specialized services that can benefit the individual such as occupational therapy, speech therapy, and applied behavior analysis (ABA).
• Tracking the progress of each child to make changes when necessary and celebrate growth.

Bilingual-bicultural approach: This approach emphasizes the use of sign language and provides a supportive learning environment that respects their specific needs alongside academic and social development.

Essential Resources and Support Networks

Many resources are available to support children and families of children with autism and deafness. These may include support groups, online forums, educational materials, advocacy organizations, and government programs. 

Services such as the American Speech Language Hearing Association (ASHA) can provide an invaluable amount of support for individuals with autism and deafness as well as their families and caregivers. 

Mental Health and Emotional Well-Being

The unique challenges faced by individuals with autism and deafness can have an impact on their mental and emotional health. They may have difficulties expressing their feelings and needs and understanding social cues. This lack of communication and social skills can lead to a variety of mental health issues and issues in emotional well-being, including:

• Anxiety
• Depression
• Reduced independence
• Meltdowns (because they may feel misunderstood)

 It is essential to prioritize emotional health when supporting individuals who are autistic and deaf. It is crucial to understand that behavior is a form of communication and challenging behaviors are often an expression of an unmet need rather than intentional misbehavior. 

Developing Emotional Resilience

Individuals with both autism and deafness can face challenges with emotional well-being. It is crucial to be aware of the risks and take steps to help them develop emotional resilience and well-being.

• Providing access to mental health professionals who have experience in helping individuals who are autistic and deaf.
• Promoting self-advocacy so that these individuals can express their needs and communicate effectively.
• Encouraging self-expression through music, art, or other creative outlets
• Establishing routines and predictable structures to reduce anxiety and promote a sense of security.

Future Directions in Research and Support for Deaf Autism 

Progress has been made in support of people with these co-occurring conditions. Below we look at some helpful tools. 

Screening and Diagnostic Tools

Traditional diagnostic tests designed for typical children may not be suitable for identifying autism in a child with hearing loss, potentially leading to missed or incorrect diagnoses. 

One tool that is commonly used is the Autism Diagnostic Observation Schedule, Second Edition  (ADOS-2). Originally it was not intended for children with sensory differences, such as deafness; however, modifications have been made to include this population, including task and scoring adaptations, but further validation is still needed. 

The Role of Interdisciplinary Teams

Due to the complexity of diagnosing autism in individuals who are deaf or hard of hearing, an interdisciplinary assessment approach is needed. This approach involves professionals from various fields, including audiology, speech/ language pathology, psychology, education, and occupational therapy. Each professional brings their specific expertise to the assessment to diagnose as accurately as possible and to ensure that the unique characteristics of autism and deafness are considered properly. 

Supporting Children Who Are Deaf and Autistic 

Deaf children with autism can greatly benefit from targeted therapeutic interventions. Therapy can teach them ways of communicating that work for them and help them be understood.  At Flywheel Center’s state-of-the-art facilities, we offer ABA therapy, speech therapy, and occupational therapy using the most up-to-date techniques and methods.
