Yes, Asperger’s syndrome is autism. Since 2013, Asperger’s has been officially folded into the broader diagnosis of autism spectrum disorder (ASD). What doctors once called Asperger’s syndrome is now typically diagnosed as Level 1 ASD, the category requiring the least support. The traits haven’t changed, but the label has.
Why the Diagnosis Changed
The shift happened when the American Psychiatric Association published the fifth edition of its Diagnostic and Statistical Manual (DSM-5) in 2013. Before that, Asperger’s syndrome, autistic disorder, and a catch-all category called “pervasive developmental disorder not otherwise specified” were all separate diagnoses. The DSM-5 merged them into a single umbrella: autism spectrum disorder.
The reasoning was largely practical. Research had shown that clinicians weren’t reliably distinguishing between these conditions. Two evaluators could see the same child and give different diagnoses depending on how they weighted certain traits. A single spectrum diagnosis, with severity levels attached, was meant to be more consistent and more useful for matching people to the support they actually need.
How Asperger’s Differed From Classic Autism
Under the old system, Asperger’s syndrome had a specific profile. Children with Asperger’s typically developed language on schedule, using single words by age two and communicative phrases by three. Their IQ scores were above 70, and they showed normal curiosity about the world around them. The core difficulties were social: trouble reading social cues, forming peer relationships, and navigating the unwritten rules of conversation. They also showed the restricted interests and repetitive behaviors common across the autism spectrum.
Classic autism, by contrast, often involved significant language delays and a wider range of cognitive and adaptive challenges. Motor difficulties were actually more common in Asperger’s than in classic autism, and the onset of noticeable symptoms tended to come somewhat later, often when social demands increased at school age. Early descriptions of the condition also noted it exclusively in boys, though that reflected the biases of early research more than the reality of who was affected.
The practical difference was that many people with Asperger’s could manage daily life independently but struggled in social settings, while people diagnosed with autistic disorder often needed more pervasive support.
What Level 1 ASD Looks Like
Most people who would have received an Asperger’s diagnosis before 2013 now fall under Level 1 ASD, defined as “requiring support.” At this level, a person may have difficulty starting social interactions, respond in ways that seem unusual or miss the mark, or appear less interested in socializing than their peers. Repetitive behaviors and fixed interests are present and can interfere with daily functioning, but with some support, redirecting from those interests is possible.
Level 2 (“requiring substantial support”) involves more pronounced communication challenges, limited ability to initiate social contact, and restricted interests that are obvious to a casual observer. Level 3 (“requiring very substantial support”) describes people with severe daily impairment, very limited verbal communication, and intense difficulty coping with change.
This three-level system replaced the old separate diagnoses. Instead of sorting people into different conditions, clinicians now place everyone on the same spectrum and describe how much support each person needs. A child might have typical language and intelligence but still need significant support for repetitive behaviors, for instance, which the old system handled awkwardly.
If You Already Have an Asperger’s Diagnosis
A pre-2013 Asperger’s diagnosis doesn’t need to be re-evaluated. The DSM-5 explicitly states that anyone with a well-established diagnosis of Asperger’s disorder should simply be given the diagnosis of autism spectrum disorder going forward. No one loses their diagnosis because of the administrative change, and no new testing is required.
That said, many people diagnosed with Asperger’s before the change still use the term. For some, it’s a meaningful part of their identity and describes their experience more precisely than the broad label of ASD. Others prefer the updated terminology because it places them within a larger community. Both are widely understood, though only ASD appears in current medical records.
Why Some People Still Say “Asperger’s”
Beyond personal preference, the name itself has become complicated. Hans Asperger, the Austrian pediatrician the syndrome was named for, was the subject of major historical investigations published in 2018. Researchers examining wartime archives found that Asperger was a member of several Nazi organizations and was aware that children under his evaluation were being sent to a facility where many were killed. He also helped save some children. The full picture is contested, but the findings prompted many in the autism community to move away from the eponymous label.
The combination of the diagnostic merger and the historical controversy means “Asperger’s” is fading from clinical and public use, though it remains common in everyday conversation and self-description.
A Related but Separate Condition
When the DSM-5 merged Asperger’s into ASD, it also created a new diagnosis: social (pragmatic) communication disorder. This condition shares some features with autism, particularly difficulty using language in social contexts. The key difference is that people with social communication disorder do not have the restricted, repetitive behaviors or intense fixed interests that define autism. ASD must be ruled out before this diagnosis can be given. For someone whose social difficulties were the primary feature of their old Asperger’s diagnosis and who doesn’t have significant repetitive behaviors, this newer category could apply.
