High-Functioning Autism: Levels, Diagnosis, & Support Options

What Is Autism?

Autism spectrum disorder (ASD) is an umbrella term for a group of neurological disorders that affect how a person communicates and behaves. Autism looks different in everyone, and some may be non-verbal while others are highly independent. The wide autism spectrum includes many different diagnoses including Asperger’s Syndrome, Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS), Rett syndrome, and Childhood Disintegrative Disorder.²

According to current diagnostic criteria, a person with autism will experience:

• Social differences: These may include difficulty understanding others’ perspectives, preferring more alone time, struggles with communicating emotional needs, and challenges with interpreting social cues.
• Sensory issues: Sensory issues may cause discomfort with certain clothing textures, smells and sounds, or food textures.
• Special interests/repetitive behaviors: Autistic individuals can become highly knowledgeable in specific topics of interest or engage in repetitive motor movements, also known as autistic stimming.

What Is High-Functioning Autism?

The term  “high-functioning” is intended to describe an autistic person who is independent and not as restricted by their symptoms as others. In the DSM-5, this would be referred to now as Level 1 as we begin to shift away from the use of high and low functioning labels.

Can Asperger’s Be Considered High-Functioning Autism?

Asperger’s has been removed from the DSM-5 and incorporated into the expanded diagnosis of Autism Spectrum Disorder.³ Many people may still associate Asperger’s with “high-functioning autism” due to this recent change.

DSM-5 Levels of “Functioning”

Although there are other terms used to describe autistic individuals, such as high and low functioning, the DSM-5 provides three levels of autism to describe the severity of one’s symptoms.

These levels help individuals and caregivers recognize the ways in which their autism impacts them, as well as learn how to manage more challenging symptoms.

Then DSM-5 levels of symptom severity include:

• Level 1: Requires Support
• Level 2: Requires substantial Support
• Level 3: Requires very substantial Support

Examples of the DSM 5 levels of autism include:

How Is Autism Diagnosed?

Autism is a complex neurological disorder that manifests in many ways. While everyone will experience slightly different symptoms, there are some common threads that can help professionals identify autism in children and adults. A clinician will look for difficulties with social interaction, delayed speech and language skills, repetitive behaviors, and other challenges associated with autism.

Autism may be diagnosed with one of the following:

• The Autism Diagnostic Observation Schedule (ADOS): This includes direct observations of an individual in order to determine a diagnosis. This tool allows a clinician the option to observe a person’s social interaction, communication, and behavior.⁵
• The Autism Diagnostic Interview, Revised (ADI-R): This tool can be used to interview caregivers about their loved ones.⁴
• The Autism Spectrum Rating Scale (ASRS): This tool is a rating scale used to identify autism by looking at variances in social responsiveness.⁶

Support Options for High-Functioning Autism

Support and treatment options for autistic individuals are varied, and can include medication, therapy, family counseling, and specialized education. There are also unique social supports offered through local organizations. It’s important to find a neurodiversity-affirming therapist and any local resources that offer a neurodiverse lens to treatment. This ensures that an approach supports an autistic person, rather than aim to change them.

Support options for autistic individuals include:

• Speech therapy: Speech therapy is used to help people learn and practice communication skills, such as vocabulary and social language. It can also be used to teach autistic children and adults how to express their emotions in ways that don’t cause emotional distress, and understand the emotions of others.
• Physical therapy: Physical therapy works to improve one’s motor skills, physical abilities, and muscle tone, as well as reduce fatigue. The goal of physical therapy is to maximize functional abilities and reduce limitations.
• Occupational therapy: Occupational therapy (OT) can help an autistic person develop skills in areas such as fine motor, gross motor, and sensory processing. The goal of OT is to promote social competence, adaptive living, and handle everyday situations.
• Sensorimotor psychotherapy: Sensorimotor psychotherapy focuses on improving one’s sensory processing, attention, and regulatory skills. This can help autistic individuals learn how to better self-regulate their behaviors and emotions.
• Applied behavioral analysis (ABA): Applied behavioral analysis (ABA) helps a client change their behavior by teaching them skills to improve their quality of life. ABA can be a controversial treatment and should be used to benefit the person, not force the person to conform to societal norms.
• Medication: Medications can be a big help in treating the symptoms of depression, anxiety, or other mental illnesses. These conditions are often common for autistic individuals, so using medication in combination with therapy can help restore balance in your life.
• Psychoeducation: Psychoeducation plays a vital role for autistic people, as it helps them understand how autism shows up for them and how to cope with it.
• Self-advocacy: As a self-advocate, you can objectively express what you need and want so others understand your thoughts and feelings. This is an important skill, because it allows you to share your experiences with caregivers and other influential people in your life.

How to Support Someone With High-Functioning Autism

Understanding how autistic people react to and view the world will help you better provide them with support. It is important to respect their feelings and needs by asking questions. For example, if you are confused about what they are trying to express, consider repeating it in a different way or even writing it down on paper for yourself.

Fighting Against the Stigma Towards Autism

When it comes to autism, much of the stigma surrounds the idea that autistic people are not as intelligent or capable as ‘neurotypical’ people. The obvious problem with this is that it’s false. Autistic people can have especially high IQs, possess unique creative thinking skills, and are often able to think in abstract ways that neurotypical individuals simply cannot. Fighting to remove the stigma associated with autism is important–not only for autistic people, but our community as a whole.
