Nonverbal Autism: What Is It, Signs & How To Deal 2023

There are several subtypes and types of autism. Nonverbal autism is one type of autism spectrum disorder, ASD. It’s often referred to as a feature of profound autism. Profound autism^[1] is characterized by challenges in communication, social interaction, repetitive behaviors, and sensory sensitivities. And it often requires extensive support and specialized interventions.

A 2023 CDC research paper stated that 26.7%^[2] of 8-year-old autistic children have profound autism. Characteristics include a low IQ, and nonverbal, or minimally verbal communication.

In this review, we look into the nature of nonverbal autism. We’ll shed light on its definition, characteristics, and common nonverbal autism signs to watch for. We also delve into practical strategies and techniques for dealing with nonverbal autism, such as alternative communication interventions.

You’ll find valuable insights for non-speaking autistic people, family members, and professionals navigating nonverbal autism.

What Is Nonverbal Autism?

When minimally verbal children on the autistic spectrum have limited or no spoken language ability, they may have nonverbal autism.^[3] Such an autistic child would say no or a few words during conversations, making communicating challenging.

Nonverbal autistic older and younger children will often face difficulties using spoken language to communicate ideas, thoughts, needs, and emotions. Instead, these minimally verbal autistic children may rely on nonverbal cues, gestures, pointing, and body language.

Nonverbal children may also communicate or learn through picture-based communication systems or assistive devices such as speech-generating devices to communicate.

Why Are Some People With Autism Nonverbal?

Most peer-reviewed studies suggest that the causes of nonverbal autism can be genetic, neurological, and environmental factors. Understanding these causes is essential for gaining insights into the development of nonverbal autism.

Early Signs Of Non-verbal Autism

The predictors of adult, adolescent, and early childhood nonverbal autism can manifest in many ways. And the nonverbal autism lifespan is indefinite since autism has no cure. Nonetheless, some early signs of autism include: 

• Communication disorders
• Limited vocabulary,
• Difficulty initiating or sustaining conversations. 

A spoken language autistic person may also feel challenged in understanding and responding to verbal instructions. You may rely on alternative modes of communication, such as sign language, to bridge most communication gaps. Get a highly individualized and comprehensive approach that addresses your unique needs and strengths. You should be keen on these signs to get the best treatment.

It’s helpful to recognize that nonspeaking autism is a spectrum. This means you can struggle with various challenges. 

Causes Of Nonverbal Autism

Here are the critical factors associated with the causes of autism spectrum disorder:

Genetic Factors

• Gene mutations: When specific gene mutations^[4] or variations related to language and communication development occur, communication becomes limited.
• Family history:  A medically reviewed study found that the family history^[5] of autism spectrum disorders increases the likelihood of autism. This indicates a genetic predisposition.
• Chromosomal abnormalities: Certain chromosomal anomalies like fragile X syndrome,^[6] deletions, or duplications^[7] in chromosomal regions associated with ASD can contribute.

Neurological Factors

These entail factors that affect your normal brain chemistry:

• Brain structure and function: Differences in brain structure,^[8] including areas involved in language processing and communication, such as the frontal and temporal lobes.
• Neural connectivity: Atypical connectivity^[9] and synchronization of neural networks that play a role in developing language and communication skills.

Environmental Influences

These are the external influences that may lead to an impede in meeting developmental milestones like speech delay. These are:

• Prenatal factors: Maternal infections^[10] during pregnancy, exposure to toxins,^[11] medications, or maternal immune system dysregulation.^[12]
• Perinatal factors: Complications during birth, premature birth,^[13] low birth weight.
• Postnatal factors: Exposure to environmental toxins^[14] may cause autism spectrum disorder.
• Parental age: Older parents have a 40%-50% higher risk^[15] of having children with ASD. Specifically, women over 35 and men over 40 are more likely to bear children on the spectrum. 

It’s important to note that the causes of nonverbal autism can vary among people. There may be multiple factors may contribute to its development. Further autism research is needed to understand the interplay between these factors and their impact on nonverbal autism.

Symptoms Of Nonverbal Autism

A nonverbal autism diagnosis is characterized by distinct symptoms^[16] primarily involving communication and social interaction challenges. If you live with nonverbal autism, you may exhibit some of the following symptoms:

• Limited or no spoken language is characterized by an inability to communicate verbally to express needs, thoughts, or emotions.
• Reliance on alternative communication methods, such as nonverbal cues and gestures.
• Difficulty initiating or sustaining social interactions, lack of reciprocal conversation, limited eye contact, and difficulties understanding social cues.
• Repetitive behaviors or movements include hand-flapping, rocking, or repetitive vocalizations.
• Heightened or reduced sensitivity to sensory stimuli, including sounds, lights, textures, or smells.
• Resistance to routine changes, difficulty transitioning between activities, and a need for predictability and sameness.
• Other co-occurring conditions^[17] frequently associated with autism spectrum disorder include mood disorders, obsessive-compulsive disorder, or ADHD.
• Motor coordination difficulties^[18], including fine motor skills required for simple activities like writing or using utensils.

The severity and combination of symptoms can vary and differ entirely from another person’s experience.

Support Options For Nonverbal Autism

After you get diagnosed with nonverbal autism, the support options available encompass a range of early interventions. These interventions enhance communication, social skills, and overall quality of life. Here are some key support options:

Augmentative And Alternative Communication, i.e., AAC

Relying on AAC systems,^[19] such as speech-generating devices, visual aids, or sign language, facilitates effective communication.

Starting early, AAC can promote language development and enhance communication abilities. By providing alternative means of communication, these strategies empower you with nonverbal autism to navigate the world and connect with others.

Additionally, AAC systems help bridge the communication gap, enabling you to be noticed, understood, and connected to society.

Picture Exchange Communication System, i.e., PECS

PECS is a structured approach using pictures to promote communication and language development. PECS may help you improve understanding contextual information^[20] like steps or details to stories.

PECS can be particularly beneficial in cases where verbal communication proves difficult or limited. This treatment provides a valuable resource for caregivers, therapists, and educators in understanding the unique communication profiles of children with ASD.

It allows for a deeper comprehension of the child’s strengths and challenges, enabling tailored interventions and support.

Speech And Language Therapy

This autistic individualized^[21] therapy targets specific communication goals. It improves articulation, expands vocabulary, and enhances social communication skills. You may find valuable online counseling for kids that offer speech and language therapy.

Speech therapists work with you to improve your language skills through techniques tailored to your specific needs.

Social Skills Training

Structured programs or therapy help to develop social interaction skills^[22]. These sessions include turn-taking, initiating and maintaining significant conversation, and interpreting social cues.

Occupational Therapy

This therapy often employs a play-based and child-centered approach to engage nonspeaking autistic individuals and make therapy sessions enjoyable. Therapists can maximize motivation and promote active participation in such therapy sessions by incorporating meaningful and functional strategies.

Addressing sensory sensitivities, motor coordination challenges, and daily living skills improves independence^[23] and overall functioning. This may include simple daily tasks and exercises for autism.

Applied Behavior Analysis, i.e., ABA

ABA^[24] implements evidence-based behavioral interventions to target communication, social, and adaptive skills through positive reinforcement and behavior modification techniques.

Its effectiveness lies in its data-driven and individualized approach. ABA therapists regularly collect and analyze stats to measure progress, identify areas of improvement, and make necessary adjustments to the intervention plan.

Assistive Technology

Speech-generating devices, like tablets with communication apps or specialized software, support communication^[25] and language skills development. 

These devices allow autistic patients to express themselves effectively by selecting and generating spoken or written messages.

Parent And Caregiver Support

Support includes providing resources, knowledge, and support groups for parents and caregivers to enhance their understanding of nonverbal autism. This helps to develop strategies for effective communication and support.

It’s essential to consider the specific strengths, challenges, and preferences when selecting and implementing support options for nonverbal autism. A multidisciplinary approach involves talking to professionals from various fields.

These specialized scientists and doctors can provide comprehensive support to address your diverse needs with nonverbal autism. If the need arises, they may prescribe certain drugs to help with the above treatments.

The Bottom Line

If you’re experiencing non-verbal autism or know someone who is, exploring augmentative and alternative communication methods may work. 

The other valuable resources are speech and language therapy, social skills training, and occupational therapy. These approaches help children with autism spectrum disorder become fluent speakers and develop social interactions. 

Plus, applied behavior analysis interventions, assistive technology, and individualized education programs offer personalized support tailored to your needs.

Finally, comprehensive support for parents, family members, and caregivers ensures a nurturing environment for growth. 

A multifaceted communication approach and considering your unique needs empower you to communicate with fluent speech meaningfully. It also helps you to engage socially and open a bright future.

Regardless, talking to a trained autism specialist gets you the best plan. Remember, every person with nonverbal autism is unique. And with the proper support, you can communicate better and reduce developmental disorders.
