Autism spectrum disorder (ASD) is a lifelong neurodevelopmental condition without a cure. In the past, this disorder was labeled either as autism or Asperger’s syndrome (also called Asperger syndrome). However, with the release of the 2013 Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) by the American Psychiatric Association, autism spectrum disorder was instead labeled as a spectrum with three levels of support needs. Below, explore these levels in more detail, as well as the controversy and history behind the name “Asperger.” In addition, find out how to seek an autism diagnosis and symptom management support.

Asperger’s syndrome: A look at the term used in early editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM) 

The term “Asperger’s syndrome” was first used in the 1980s to describe people with “high-functioning autism” or autism with lower support needs. British psychiatrist Dr. Lorna Wing, co-founder of the National Autistic Society, coined the term, citing the work of Hans Asperger, a scientist who noted differences between Autistic children when studying how they socialized and behaved. He noticed that some children were more capable of communicating socially and living independently. Because of his findings and social skills training efforts, he posited that there were several Autistic spectrum disorders and pervasive developmental disorders instead of one singular type of autism.

Why is “Asperger’s syndrome” no longer used? The historical controversy of labeling autism spectrum disorders 

Although the term “Asperger’s syndrome” was used for many years as a diagnostic label for individuals with lower support needs than others with autism, the term is controversial. Although this work led to what society now understands as autism spectrum disorder, Hans Asperger’s work was highly controversial. 

Asperger himself worked with the Nazis during the Holocaust, running experiments and studies on Autistic children. In his work, he reportedly said that Autistic children were unworthy of love and care from their families. Because of his work, many Autistic children were sent to a Nazi clinic to be studied. As a result, the children were murdered. This finding is often seen as controversial because some people don’t believe Hans Asperger knew that the Nazis would harm the children. 

However, recent research suggests that Hans was aware he was sending the children to their deaths, and the clinic had been referred to as a “euthanasia” clinic when he first connected with it. There are also reports of Asperger’s racism and agreement with the Nazi party’s views on racial purity.

What if someone wants to identify with this label?

Because Asperger was associated with Nazism, the term “Asperger’s syndrome” is no longer used to describe individuals with autism who have lower support needs. However, some people continue to use this term because they don’t know the history behind it or find the term is the best fit for them. In other countries, this term is still widely used. Although identity labels are a personal choice, considering the history behind the term may be helpful when understanding why others might not appreciate the use of this label to describe autism. Instead of using “Asperger’s,” you might use the level system as outlined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR). 

Understanding autism spectrum disorder (ASD) 

Autism spectrum disorder was labeled as a spectrum in the most recent edition of the DSM, partly because Asperger's research identified different presentations of the condition. However, many newer researchers have expanded on this research in ethical ways, moving away from the idea that some Autistic children are “better” or “worse” than others. The leveling system determines the level of support that Autistic children and adults require for optimal function. 

Level one autism: Previously known as Asperger’s syndrome 

Level one autism spectrum disorder is referred to as “requiring support.” People with this type of autism may have previously been identified with Asperger’s syndrome, which was considered a “milder” form of autism due to better communication and social skills. However, even though this is the lowest level of support needs, people with level one autism can still struggle significantly and require support in certain areas. Because autism is a spectrum, what one person on this level struggles with may be completely different from someone else’s struggles. For example, one person might be able to socialize well but struggle with rigid thinking and masking behaviors. Another might struggle to socialize but could be highly organized and able to maintain employment. 

Level two autism

In the DSM-5, level two autism is referred to as “requiring substantial support.” Those with this level of autism typically have more noticeable difficulties in social interaction and independent living. They might struggle to hold a job, maintain relationships, and connect with others in society. Some people with level two autism struggle with verbal and nonverbal communication. They may have more rigid thought patterns and struggle significantly with sensory input and language development. As with the other levels, people on this level can have varied struggles, and not all people with level two autism have the same difficulties.

Level three autism 

Level three autism is referred to as “requiring very substantial support.” Those categorized into this level usually have severe social deficits, difficulty with sensory input, and rigid, unmoving behaviors. They might be nonverbal, meaning they do not communicate through speech. Those on this level often require constant support and may never have jobs, relationships, or independent lives. As adults, they may live in a group home or clinical environment. 

Some people with level three autism do speak verbally. Although this level requires more support from external sources, it is not necessarily more “severe” or “important” than other levels. Still, advocacy work in the autism community might look at how to integrate conversations about all levels of autism without invalidating or pointing fingers at one or the other. When looking at what those with profound autism require to be supported in the community, invalidating other Autistic individuals or the family members of any Autistic child may not be helpful.

Understanding neurodiversity: A different way of viewing autism 

Although autism is clinically organized into a level system, the levels themselves do not explain the full spectrum of Autistic individuals. Many people identify as “neurodivergent” as well as Autistic. The neurodiversity movement posits that all Autistic people are unique and that the spectrum can be as varied as an infinity symbol. For this reason, some people use the rainbow infinity symbol for autism awareness instead of the blue ribbon. 

Within the neurodiversity movement, people may identify more as an “Autistic person” than “someone with autism.” Autism can be seen as an identity that might not be associated with disability or difficulties if society were to change to better accommodate Autistic individuals. Some may argue that autism would not be seen as a disability at all if society were fully open to accommodating the sensory, emotional, and structural needs of Autistic people. However, critics of this movement cite the difficulties of those living with “profound” autism or level three autism, who might not be able to share their voices in this conversation and could disagree. Some people believe that autism is disabling and would be disabling regardless of whether society changed. 

The choice to identify with neurodivergence is a personal one. You don’t have to identify with this term if it doesn’t fit you. Overall, the idea of neurodiversity is about inclusion, equity, and understanding. Instead of judging Autistic children and adults for their natural stimming, personality traits, and unique interests, the theory of neurodiversity encourages society to accept the differences in how people’s minds work. Although many Autistic people struggle, studies also show that Autistic people tend to be more intelligent than “neurotypical” individuals in many areas, including decision-making, intentional focusing, sensory abilities, and synaptic functioning.  

How to get a diagnosis for your child

If you’re seeking an autism diagnosis for your child, reach out to your child’s primary care pediatrician. They can potentially refer you to a testing provider that takes your insurance. You may also look into autism diagnostic centers in your area. A therapist may be able to offer an evaluation as well. An official assessment usually involves testing tools, interviews, and analyses. These tests can be expensive and often involve several appointments. You might be able to get funding for these tests in your area, especially if you’re struggling to pay for support for your child.

Many providers on BetterHelp now accept major insurance carriers. In many states, certain therapists on BetterHelp may be in-network with certain insurance plans. Coverage depends on your plan, provider, and availability. 

When sessions are covered, members typically pay an average copay of about $19 per session. Check your in-network status on the BetterHelp site. Coverage varies by state and provider availability.

Getting an autism diagnosis as an adult based on the Diagnostic and Statistical Manual of Mental Disorders 

Many people aren’t diagnosed with autism until adulthood because their needs may not have been recognized as autism during their childhood years. Autism has only been studied in adults, women, and girls more recently, so many people were left out of early autism research. Initially, autism was thought to be a disorder that primarily impacted young white boys, who were the only participants in early studies. For this reason, many women may enter adulthood wondering how to seek a diagnosis if they weren’t taken seriously in childhood or if their symptoms were overlooked.

Adults can receive autism diagnoses, and there are many testing tools psychologists can use to identify symptoms. The provider may ask about your childhood symptoms, as signs of autism in childhood are required for you to receive a diagnosis in adulthood. In addition, they may ask you how your symptoms impact your daily function in areas like socialization, work, and independent living.

How is autism treated? 

Autism has no cure. Often, the best treatment recommended for autism is one that supports daily function in the child or adult client. Some people may require more support than others, which can look like more frequent therapy sessions. When seeking treatment, families often consider individual and group therapy, occupational support, family therapy, and long-term classes for supporting children with high support needs. 

If you’re seeking therapy for your child, look into the ethical considerations of each type of therapy and study all options in depth before choosing. Some autism treatments may be harmful, potentially leading to symptoms of post-traumatic stress disorder (PTSD) in Autistic children. In addition, remember that autism is a spectrum. Even those within the same level can vary widely in needs. Some children respond well to frequent treatment, whereas others may become easily distressed in these environments.

Mental health support options 

Caregivers and loved ones of children with autism, as well as Autistic adults, may also benefit from support. Therapy can be a helpful way to cope with symptoms of stress, anxiety, depression, and autism in daily life. One option that might be more accessible to those with limited time is online therapy through a platform like BetterHelp. With online therapy, you can attend sessions via phone, video, or live chat at any time that works for you. In addition, online therapy is often more cost-effective than in-person options. 

Studies have found online therapy especially effective for Autistic adults and adolescents. For example, a 2021 study reported that online therapy could be an accessible treatment for adults with autism, potentially leading to less energy expenditure. Many participants in the study appreciated the text-based form of communication, which allowed them to receive accessible support and communicate more effectively without having to meet face-to-face.

Takeaway

The term “Asperger’s syndrome” was initially used to diagnose people who had autism with lower support needs. However, this term is no longer used in a clinical setting due to the controversy surrounding the doctor after whom the terminology is named. Autism spectrum disorder is now organized into three levels, depending on one’s support needs. For more information and support, whether you or a loved one is living with autism, consider seeking support from a therapist online or in your area.
