What happened to Asperger’s syndrome?

If you were diagnosed with Asperger’s syndrome, the question is not just historical. It may be the name on an assessment report, the word through which you made sense of yourself, or the way you first found other people who recognised something familiar.

The category changed. The history around the name changed too. Neither fact requires you to pretend that an earlier diagnosis was unreal, or to adopt a particular identity now.

This guide separates three things that are often muddled together:

1. Hans Asperger’s clinical work in Vienna during the 1930s and 1940s;
2. Lorna Wing’s later clinical account and the development of Asperger syndrome as a diagnosis; and
3. the later decision to replace separate autism subtypes with autism spectrum disorder.

A fourth history matters as well: the archival research that changed the public understanding of Hans Asperger’s conduct under National Socialism. It is grave, but it is not the reason DSM-5 removed Asperger’s disorder in 2013.

A diagnosis that existed, and then changed

For a substantial period, Asperger syndrome was a formal diagnostic category. It appeared in ICD-10 as F84.5 and in DSM-IV as Asperger’s Disorder. People were assessed against criteria in use at the time; their diagnosis was neither imaginary nor retrospectively foolish because classifications later changed.[2]

The old categories did try to describe a particular profile. DSM-IV placed Asperger’s Disorder among the pervasive developmental disorders. It required social-interaction difficulties and restricted, repetitive interests or activities, while specifying no clinically significant general delay in language or cognitive development. Its rules also contained a difficult precedence condition: the diagnosis could not be given if the person met criteria for Autistic Disorder. ICD-10 likewise treated Asperger syndrome as a separate named category, alongside autism-related social-interaction and restricted-interest features and no general language or cognitive delay.[2]

That was not simply a polite way of saying “mild autism”. Language history, intellectual development, social communication, interests, development and day-to-day support can each matter in different ways. The older category was experienced as meaningful precisely because it appeared to recognise a pattern that did not fit the public stereotype of autism at the time.

But a formal category can be real in a diagnostic system without being a stable natural boundary. Over time, research and clinical practice raised a different question: could clinicians apply the boundary between Asperger’s Disorder, Autistic Disorder and PDD-NOS reliably and usefully across settings? Reviews of the DSM change describe overlapping profiles, inconsistent assignment of subtypes and weak evidence that the old subtypes reliably predicted later outcome or a distinct cause.[4]

That is the background to the merger. It was a change in classification, not a finding that people who had received Asperger diagnoses had somehow been misdescribed as people.

Hans Asperger’s work was not the later diagnosis

Hans Asperger was a paediatrician working at the University Children’s Clinic in Vienna. In a 1944 paper he described a group of children using the term autistic psychopathy. The historical term needs its own context: he used psychopathy in an older technical sense, not in the current everyday sense of cruel or antisocial behaviour.[3]

His published account included children with unusual social interaction and communication, intense or narrow interests, and uneven abilities. The phrase “little professors” later became widely associated with descriptions of some of these children. It should not be treated as a diagnosis, a compliment owed to autistic people, or an accurate shorthand for everyone later given an Asperger diagnosis. Asperger’s own clinical material was broader and more troubling than the familiar phrase suggests.

Nor did Hans Asperger invent the DSM-IV category. Lorna Wing coined and used the English term Asperger’s syndrome decades later, drawing on his work but also interpreting it through her own clinical experience and her developing account of autism as a spectrum. The later diagnosis was shaped by Wing, subsequent criteria and clinical practice; it was not a direct preservation of a 1944 case series.[3][4]

What Lorna Wing did — and did not — do

Lorna Wing’s 1981 paper, Asperger’s syndrome: a clinical account, brought Asperger’s work to far wider English-language attention. Importantly, her synopsis argued for including Asperger syndrome and early childhood autism within a wider group of conditions sharing impairments in social interaction, communication and imagination.[3]

That can sound surprising now, because a later diagnosis bearing Asperger’s name was often experienced as a useful distinction. Both things can be true. Wing was interested in variation across autistic people and in a spectrum approach, while also describing a recognisable clinical pattern that had been neglected in English-language discussion.

It would be wrong to present Wing as knowingly choosing the name of a man whose Nazi-era record she had simply decided to overlook. Her 1981 paper did not discuss the political history of Asperger’s work. The protective account of Asperger — a doctor said to have defended vulnerable children from Nazi policy — remained influential in English-language autism writing for decades. The fuller archival evidence that challenged that account was not available to her in 1981.[1]

Wing’s contribution therefore needs its own place in this history. It was not merely a handover from one clinician to another. Her work helped make autism’s heterogeneity visible and helped create the diagnostic territory in which many later adults were assessed.

Why the separate diagnosis was merged

DSM-5, published in 2013, replaced Asperger’s Disorder, Autistic Disorder and PDD-NOS with autism spectrum disorder. The rationale was clinical and empirical: the previous subtype boundaries were difficult to apply consistently, overlapped considerably and were not supported as robust, reproducible divisions. The new system aimed to describe the individual profile alongside the diagnosis rather than make a categorical distinction depend heavily on retrospective memories of early language milestones or the clinic doing the assessment.[4]

This is also why the idea that “Asperger’s and autism were the same thing all along” is too blunt. The previous system did make a distinction, people were diagnosed under it, and the distinction could shape identity, relationships with services and self-understanding. The later system concluded that this particular categorical division was not reliable or useful enough to retain as a separate diagnosis. That is a narrower claim than saying that all individual differences vanish inside a spectrum.

The dates matter. DSM-5 made the merger in 2013. The major archival research by the medical historian Herwig Czech, which substantially changed public discussion of Asperger’s Nazi-era record, was published in 2018. The DSM-5 change was therefore not a response to those later revelations.[1][4]

ICD-11 took a related but not identical approach. It uses autism spectrum disorder and records combinations relating to intellectual development and functional language. For example, 6A02.0 is autism spectrum disorder without disorder of intellectual development and with mild or no impairment of functional language. In the WHO’s ICD-10-to-ICD-11 mapping, F84.5 Asperger syndrome is shown against that category.[6] That does not make the categories identical. ICD-11 uses a different classification structure, but it does provide a route from the older term into the current system.

The later reckoning with Hans Asperger

For years, a popular account portrayed Asperger as a principled opponent of National Socialism and protector of children in his care. Czech’s 2018 archival study tested that story against personnel records, Nazi political assessments and surviving patient records, including records from Asperger’s ward and Am Spiegelgrund.[1]

Several points are documented in that research. Asperger did not join the Nazi Party. At the same time, Czech documents his memberships in Nazi-affiliated organisations, public accommodations to Nazi ideology, favourable political assessment by the authorities, and professional advancement under the regime. Czech’s account does not require the false choice between “secret resistance hero” and a simplified label that explains everything.[1]

The evidence concerning Am Spiegelgrund is particularly important. Czech documents that Herta Schreiber was transferred there on Asperger’s authority and died there two months later. He also analyses Asperger’s recommendation of Spiegelgrund as the preferred option for Elisabeth Schreiber, who was later transferred there. Am Spiegelgrund was a place where disabled children were killed within Nazi child “euthanasia”.[1]

There are limits on what a historical record can settle. It cannot give us a complete interior account of what Asperger knew at each moment or why he made every clinical recommendation. A later article by Dean Falk disputed Czech’s interpretation, including whether Asperger knew the fate facing children sent to Spiegelgrund. Czech replied in detail, arguing that Falk’s case rested on historical errors and mistranslations, and that it was implausible Asperger could have been unaware of the danger.[8][9]

A 2023 re-examination of referral and admission records also reached a more limited conclusion about what can be proved of Asperger’s knowledge at the time of the two 1941 referrals. It documented the referrals and the deaths, but argued that the available evidence did not establish that he knew of the killing programme then. This differs from Czech’s 2018 interpretation of the available contextual evidence. The careful point is not that historians have resolved every question of knowledge or intent; it is that the old uncomplicated account of Asperger as a protector is no longer supportable in light of the archive.[1][15]

ZenEmu’s conclusion is deliberately restrained: the archival record makes the heroic protector story untenable. It documents conduct and institutional accommodation that many people reasonably find incompatible with continuing to use the eponym. It does not require us to turn historical explanation into a slogan, or to pretend that a person’s later Asperger diagnosis was a personal endorsement of Hans Asperger.

What does an old Asperger diagnosis mean now?

It remains an accurate record of what you were diagnosed with under the classification used at the time. DSM-5 said that a person with a well-established DSM-IV diagnosis of Autistic Disorder, Asperger’s Disorder or PDD-NOS should receive an autism spectrum disorder diagnosis, or another more appropriate DSM-5 diagnosis. It did not frame the terminology change itself as a requirement for everyone to seek a new assessment.[11][12]

In the UK, the National Autistic Society says Asperger syndrome is no longer used as a diagnostic term, while recognising that some people who received the diagnosis continue to use it for themselves and others do not.[2] NHS England describes autism spectrum disorder as the official ICD-11 name, while noting the practical transition from ICD-10 in records systems.[13] We have not found an authoritative UK source saying that a person with a historical Asperger diagnosis must be reassessed solely because terminology has changed. If a current employer, university, service or clinician needs a particular form of evidence, ask what they actually need rather than assuming the old wording is automatically inadequate.

The guide does not make broader claims about benefits, reasonable adjustments or NHS records because those arrangements depend on the specific setting and current evidence of need. The name of a past diagnosis alone is not a reliable guide to what support a person may need now.

What should you call yourself?

There is no ZenEmu-approved answer.

Some people still use Asperger’s or Aspie. Some use autistic. Some use both depending on the audience or are still deciding. Some find the term inseparable from a diagnosis that helped them understand their life. Others reject it because of the man it honours or because the wider autism spectrum describes them better.

Small qualitative studies support the fact of divergent reactions, rather than one correct reaction. One Australian interview study involved 12 adults previously diagnosed with Asperger’s and found varied responses related to how participants integrated Asperger’s and/or autistic identities. A small UK study of nine young men reported that its participants often valued the Asperger label and worried about its removal. These studies are useful evidence that the loss of a label can matter; neither is a basis for speaking for everyone.[7][16]

The history can explain the word without deciding what you have to call yourself.

A short chronology

• 1944: Hans Asperger publishes a paper on “autistic psychopathy” in Vienna.
• 1981: Lorna Wing publishes Asperger’s syndrome: a clinical account, bringing the work to wider English-language attention and placing the pattern within a wider autism-related group.[3]
• 1992/1994: Asperger syndrome becomes a formal category in ICD-10 and DSM-IV respectively.[2]
• 2013: DSM-5 incorporates Asperger’s Disorder into autism spectrum disorder, for reasons concerning the validity and reliability of the old subtype boundaries.[4]
• 2018: Herwig Czech publishes extensive archival research reassessing Asperger’s conduct under National Socialism.[1]
• ICD-11: WHO’s newer structure uses autism spectrum disorder with categories relating to intellectual development and functional language, rather than a named Asperger syndrome diagnosis.[6]
