MYTH: Nonverbal or Nonspeaking People with Autism are Intellectually Disabled

Just because someone is nonspeaking, does not mean they’re non-thinking. Around 25 to 30 percent of children with autism spectrum disorder are minimally verbal or do not speak at all. These individuals are referred to as nonverbal or nonspeaking, but even the term nonverbal is a bit of a misnomer. While nonspeaking individuals with autism may not speak words to communicate, many still understand words and even use written words to communicate.  

Nonspeaking individuals with autism utilize a variety of augmentative and alternative communication (AAC) methods. These range from no-tech and low-tech options such as gestures, writing, drawing, spelling words, and pointing to photos or written words, to high-tech options like iPads or speech-generating devices. 

There are several reasons that an individual with autism may have difficulty talking or holding conversation that are not related to intellectual disability. The disorder may have prevented the normal development of verbal communication skills. They may also have conditions such as apraxia of speech, which affects specific brain pathways, making it difficult for a person to actually formulate and speak the words they’re intending to say. Some may also have echolalia, which causes a person to repeat words over and over again.

While these conditions prevent many individuals from speaking, it does not mean they cannot learn, understand, or even communicate. There is a pervasive misunderstanding about this among the general population due to a lack of education. It is often wrongly assumed that anyone who has difficulty speaking is intellectually disabled.

This misconception can be particularly harmful when held by medical professionals. In the 1980s, as many as 69 percent of people with an autism diagnosis had a dual diagnosis of mental retardation, which would now be labeled intellectual disability. By 2014, that number had declined to just 30 percent, as researchers improved the diagnostic criteria for autism and a fuller picture of the disorder emerged.

Researchers are still working to try and improve diagnostics and better distinguish nonspeaking autism from intellectual disabilities. As Audrey Thurm, a child clinical psychologist at the National Institute of Mental Health in Bethesda, Maryland says: “We have to figure out who has only autism, who has only intellectual disability and, importantly, who has both intellectual disability and autism. That’s millions of people who could be better served by having an accurate distinction that would put them in the right group and get them the right services.”

It’s important to challenge the perception that those who do not speak cannot think. Not only do we risk failing to give them the proper supports and services, but we also undermine their individuality, ingenuity, creativity, and humanity by failing to see them as they truly are. Just because they are not talking does not mean they do not have much to tell us.

Brain Plasticity & Early Intervention: “Neurons that fire together, wire together”

by

The following is based on a conversation Ronit Molko, Ph.D., BCBA-D and Dr. Evian Gordon, Chairman and CEO of Brain Resource.

The development of the brain is a fascinating and essential aspect of child development. The science behind the brain provides parents and practitioners valuable insight as to why early intervention is important for individuals with autism and other developmental disabilities.

At birth, a child’s brain is a work in progress. It develops as they experience the world through seeing, hearing, tasting, touching, and smelling the environment. The natural, simple, loving encounters with adults that occur throughout the day, such as a caregiver singing, smiling, talking, and rocking their baby, are essential to this process. All of these encounters with the outside world affect the child’s emotional development and shape how their brain becomes wired and how it will work.

The experiences of babies have long-lasting effects on their ability to learn and regulate their emotions. When there is an absence of appropriate teaching and learning opportunities in the baby’s environment, the brain’s development can be affected and there are more likely to be sustained negative effects. Conversely, if we can provide ample learning opportunities, we can facilitate brain development. Let’s understand how and why.

Learning is about connection. A baby is born with more than 85 billion neurons in its brain, the major nerve cell of the brain. Neurons transmit information between each other through chemical and electrical signals via synapses thereby forming neural networks, a series of interconnected neurons. This is what is meant by “the wiring of the brain” and “neurons that fire together, wire together”. Neurons and synapses grow exponentially in the first years of life, even before a baby can walk and talk. Between birth and about 3 years of age, the number of synapses in the brain increases from about 2,500 to 15,000 per neuron.

As an infant experiences something or learns something for the first time, a strong neural connection is made. If this experience is repeated, the connection is reactivated and becomes strengthened. If the experience is not repeated, connections are removed. In this way, the brain “prunes” what is not necessary and consolidates the connections that are necessary. During infancy and the first years of childhood, there is significant loss of neural pathways as the brain starts to prune away what it doesn’t believe it will need to function. By the time your child reaches adulthood, the number of synaptic connections is reduced by half. Therefore, the earlier in a child’s development that we create that first, correct learning experience, the stronger those behaviors and skills are secured in the brain.

Children with developmental delays often experience the wiring of neurons together in a manner that is “unhelpful”, causing them to struggle with communication, social skills and other activities. These “unhelpful” connections need to be changed, which adds to the challenge and takes time. Technically, learning cannot be undone in the brain, but amazingly, with stimulation, the brain has the ability to re-process new pathways and build circuits that are helpful and functional. The brain has a remarkable capacity for change and adaptation, but timing is crucial. The earlier we create the correct connections in a child’s brain, the stronger those behaviors and skills are secured in the brain.

Intervention is best during early childhood when there are 50 percent more connections between neurons than exist in the adult brain. When a child reaches adolescence, another period of pruning begins where the brain starts to cut back on these important brain connections, and neurons that have not been used much. For children with all types of learning difficulties and developmental disorders, this understanding of the brain’s plasticity is particularly relevant, because it emphasizes why the correct type and intensity of early intervention is so critical. If we correctly understand a child’s skill deficits and design a program that appropriately stimulates the neurons in the targeted weakened areas of the brain, we can exercise and strengthen those areas of the brain to develop language, social skills etc.

While there is much evidence to support that early intervention is the preferred course of action because it capitalizes on this rapid early brain development, this wisdom often leaves parents or caretakers of teenage children with ASD feeling discouraged and concerned. Many children don’t have the opportunity to start therapy when they’re younger, and many others aren’t diagnosed until they’re teenagers. It may be easier and faster for children to learn new skills when they are younger, however, neuroscience tells us that the brain is still capable of learning during adolescent years, and this time period should not be forsaken.

So how do you train your child’s brain? In order to change the brain’s wiring and make new neural connections, a new skill needs to be practiced many times. Dr. Gordon recommends starting with one, simple task and practicing it at least 10 times per day. Measure how long it takes for your child’s behavior to change. This will help you determine your child’s rate of learning.

An example of a simple task is teaching your child to follow a simple instruction using a preferred item such as asking him to eat his favorite food. You can then move onto a more complex activity such as requesting eye contact by saying “Look at me” and then something more complex such as “touch the car” when playing with a toy car, for example. There are many opportunities throughout the day during normal daily parenting activities (bathing, feeding, diapering, reading, etc.) during which you can support your child’s development and train their brain to respond to people and their environment.

One common question is, “What is possible with the brain after childhood?” For many years, science has told us that brain plasticity is at its peak during childhood. However, experts now believe that under the correct circumstances, practicing a new skill can change hundreds of millions, if not billions, of connections between nerve cells in the brain even into adulthood. It is never too late to start. The most important thing to remember is that learning is what changes the brain and learning takes practice. Every opportunity to teach your child is an opportunity to shape their brain and change their future.

Neurodiversity: What It Means, Why It Matters

by

BY RONIT MOLKO, PH.D., BCBA-D
STRATEGIC ADVISOR, LEARN BEHAVIORAL

If there is one enduring hallmark of the American experience, it’s the immense diversity found within our expansive borders. Most of the time, we perceive diversity via differences in skin color, language, clothing, places of worship, or even the foods people eat when gathered around the table with their families. There is, however, one major aspect of diversity that is often overlooked—one that comes as no surprise, considering it cannot be detected solely through visual means. I am, of course, referring to neurodiversity.

Coined in the late 1990s by sociologist Judy Singer—who is on the autism spectrum—neurodiversity is a viewpoint that characterizes brain differences among individuals as normal, rather than as a disability. This viewpoint reduces stigmas around learning and thinking differences, while calling attention to the ability of neurodivergent communities to benefit from multiple perspectives and make greater contributions to society. Central to the movement is a rejection of the idea that these unique individuals need to be cured or fixed. Instead, it’s held that people possessing different types of brains need to be embraced and provided support systems that allow them to participate and contribute as members of the community to the best of their ability.

Grounded in Science

Unsurprisingly, the foundations of this not so new movement are grounded firmly in science and empirical study. By leveraging MRI results from hundreds of individuals, researchers have been able to compare the brains of people diagnosed with learning differences to their counterparts. So far, studies have shown that the brains of neurodivergent individuals are, in fact, unique. For example, the part of the brain that maintains language processing works differently for people diagnosed with dyslexia. Additionally, the prefrontal cortex, which manages executive functioning and attention, develops much slower in children diagnosed with ADHD. In other words, these individuals are not necessarily operating with a learning deficit but rather possess brains that are literally wired differently.

A Neurodiverse Population

Whether a group of kids recently diagnosed with autism or adults still grappling with ADHD or dyslexia, the American neurodiverse population is quite substantial. According to a 2021 report from the Center for Disease Control and Prevention, one in every 44 children in the United States is diagnosed with some sort of autism spectrum disorder, and an estimated 5.4 million adults—or roughly 2.2 percent of the entire population—fall somewhere along the spectrum. Many people on the spectrum have contributed (or still do) to their communities every day, such as Albert Einstein, Anthony Hopkins, Henry Cavendish, Greta Thunberg, Jerry Seinfeld, and Elon Musk. They have been among the world’s highest achievers, impacting the arts, sciences, technological innovation, and activism.

In much the same way as the neurotypical population, the neurodivergent population is broad, diverse, and multidimensional. It’s crucial, then, for the public not only to embrace their different brethren but also to actively promote opportunities for them both in society and in the workplace at all abilities and levels.

Fortunately for society writ-large, corporate America is starting to take notice. A recent article published in the Harvard Business Review named neurodiversity as a bona fide “competitive advantage,” noting the unique and, often, incomparable output provided by atypical members of their workforce. Numerous companies, including Hewlett-Packard, Enterprise, Microsoft, SAP, and Ford, have recently begun to reform their HR practices in an effort to expand neurodiversity in their ranks by identifying, hiring, and empowering these unique individuals. The results, so far, have been outstanding, with managers noting legitimate “productivity gains, quality improvements, boosts in innovative capabilities, and broad increases in employee engagement.”

Diversity of all kinds, including neurodiversity, strengthens our daily institutions. Just as we are seeing a focus on diversity, equity, and inclusion (DEI) in employment and other areas of life and commerce, we must also remember that recognizing and celebrating differences, promoting justice and fairness, and ensuring true support and inclusion applies not only to people with observable differences but also to our neurodiverse populations. Not all cognitive differences are visible, and it’s crucial to keep in mind that there’s more than meets the eye when it comes to true diversity.

Why Adherence to Your Behavior Analyst’s Clinical Recommendation is Critical to Success

by

Parents and caregivers will do just about anything to provide for their children’s needs and requirements.  Unfortunately, for those whose children require additional supports and services, this can feel nearly impossible. For parents and caregivers of children on the autism spectrum, who are already struggling to meet the demands of their schedules and responsibilities, the added time and energy required to support intensive weekly ABA therapy hours can be difficult and overwhelming. The result is quite often a compromise on therapy hours which can seriously impact the child’s progress.

What commonly occurs in autism services is parents will seek ABA therapy for their child, knowing that it is considered the gold standard for autism intervention with decades of research and evidence to support its efficacy. As part of this process, the ABA provider will observe and assess the child, as well as interview the family to determine their recommendation for weekly hours of ABA services based on the child’s needs, age, and other determining factors. What we commonly see, however, is families not making their children available for the recommended hours. While not being able to reach the clinically recommended hours is affected by multiple factors such as family schedules, staffing issues, sickness, weather and other extenuating factors, lack of access to the child often accounts for anywhere from 5-40% of weekly clinically recommended hours not occurring.

Families who do this are typically trying to compromise between their child’s needs and the demands of their other responsibilities—and managing and navigating the needs of a child with special needs alongside all the competing needs and requirements of daily life is challenging. However, if one looks at this objectively, it is akin to getting a prescription from a doctor and telling the pharmacist to only give you part of it. Most families assume that with fewer hours per week, their child will still progress and learn new skills but at a slower pace. Unfortunately, this is not necessarily the case.

It is true that ABA therapy is unique in its intensity, but this is a core component of why ABA is so effective. ABA is effective at helping a child catch up to and develop alongside their chronological age when the recommendation for frequency and intensity of services is adhered to. There are decades of research to support the efficacy of ABA at teaching the skills necessary for communication, social interactions and self-management. In a recent research study which included 1,468 children with autism ranging in age from 18 months to 12 years old, treatment intensity and duration were both significant predictors of mastering learning objectives and goals across eight domains of functioning (academic, adaptive, cognitive, executive function, language, motor, play and social). Similar findings have been reported from other researchers over the decades. Overall, studies have strongly indicated that treatment intensity has significant positive effects on individual progress and the acquisition of skills.

Intensity or “dosage” of treatment will vary by client and should always be individualized to the child’s needs and goals. Generally, for children under the age of 5, more intensive hours are recommended to capitalize on the intensive brain growth during the first 5 years of age and to stimulate a child’s brain before children enter Kindergarten. Once a child is engaged in learning at school at least 3 hours per day, treatment recommendations generally include 15-20 hours per week. Again, recommendations for intensity and duration of intervention should always be based on a detailed assessment of your child’s needs, level of functioning compared to other children of their current age, and your child’s individual goals.

It’s very important that parents and caregivers of young children with autism spectrum disorder understand that ABA is the gold standard of treatment but is only most effective when the program recommendations are adhered to entirely. The structure and design of an ABA program is essential to its outcomes. While it is understandable that parents are trying to do their best to meet the demands of their family’s schedule, it is vital to consider the research when making decisions regarding how to prioritize interventions. Finding that extra time every week to ensure that your child is receiving their recommended amount of ABA can make a huge difference in their life and yours.
