Asperger's vs Autism: What's the Difference?
If you're searching for Asperger's vs autism, you may be wondering whether they are two different conditions. The main difference is that Asperger's syndrome was once a separate diagnosis, but it is now included under autism spectrum disorder (ASD) in the current diagnostic system used in the United States.
The term Asperger's is still used by some people to describe their identity or past diagnosis. Understanding the terminology can help you learn more about autism and the different ways it can affect people.
What Was Asperger's Syndrome?
Asperger's syndrome was a diagnosis used for people who experienced differences in social communication and had restricted interests or repetitive patterns of behavior, without the same early language delays typically associated with some other autism diagnoses.
People diagnosed with Asperger's often had average or above-average intellectual abilities, but they could still experience challenges with social situations, sensory input, changes in routine, or everyday responsibilities.
In 2013, the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) combined Asperger's syndrome and several other previously separate diagnoses into autism spectrum disorder.
What Is Autism Spectrum Disorder?
Autism spectrum disorder is a neurodevelopmental condition that affects social communication and involves restricted or repetitive patterns of behavior, interests, or activities. Sensory differences may also be part of the experience.
Autistic people have different strengths and support needs. Some may need substantial daily support, while others live independently but experience difficulties that are less visible to others.
Common autistic traits can include:
- Communicating or interpreting social situations differently
- Having strong, focused interests
- Preferring routines or finding unexpected changes difficult
- Repeating certain movements or behaviors
- Being unusually sensitive or less sensitive to sounds, lights, textures, or other sensations
Not every autistic person experiences all these traits, and no single characteristic confirms an autism diagnosis.
Asperger's vs Autism: Key Differences
Historically, Asperger's syndrome was used for a particular group of people on the autism spectrum, especially those without significant early language delays. Today, those individuals may receive an autism spectrum disorder diagnosis.
| Asperger's syndrome (historical term) | Autism spectrum disorder |
|---|---|
| Was a separate diagnostic category | Is the current broader diagnostic category |
| Usually did not involve significant early language delays | Can involve a wide range of language and communication profiles |
| Often associated with average or above-average intellectual ability | Includes people with varied intellectual abilities |
| Was diagnosed under older criteria | Assessment considers current autism diagnostic criteria and individual support needs |
These distinctions describe historical diagnostic criteria, not strict rules about how autistic people behave. Language ability or intelligence alone does not determine whether someone is autistic.
Is Asperger's Still a Diagnosis?
In the United States, Asperger's syndrome is no longer a separate diagnosis under the DSM-5 and DSM-5-TR. The World Health Organization's ICD-11 also places these presentations within autism spectrum disorder.
However, people who received an Asperger's diagnosis in the past may continue using that term. Some prefer it because it reflects their personal history or identity. Others prefer autistic or autistic person.
It is generally best to respect the terminology someone uses for themselves rather than assuming which label they prefer.
What Are the Signs of Asperger's in Adults?
People searching for Asperger's in adults are often trying to understand long-standing differences in communication, routines, interests, or sensory experiences.
An adult might find small talk confusing, prefer direct communication, become deeply absorbed in a particular interest, or feel overwhelmed by noisy environments. They may also find unexpected changes stressful or need time alone after social activities.
These experiences can occur in autistic people, but they can also have other explanations. An assessment looks at developmental history, current traits, and how these patterns affect everyday life.
Can You Have Asperger's and Autism Together?
Under current diagnostic criteria, Asperger's syndrome is not considered a separate condition alongside autism. It is an older diagnostic label that now falls within the broader autism spectrum.
If you previously received an Asperger's diagnosis, that does not mean your experiences have suddenly changed. The terminology and diagnostic framework changed, while your individual strengths, challenges, and support needs remain important.
If you think you may be autistic, a qualified healthcare professional with experience in autism assessment can help you understand your experiences and discuss possible next steps.
Final Thoughts
When comparing Asperger's vs autism, the key point is that Asperger's syndrome was a historical diagnosis that is now included under autism spectrum disorder. Autism is a spectrum, and people vary widely in their communication styles, abilities, sensory experiences, and support needs.
