Understanding Asperger Syndrome: Why the Term Is No Longer Used
What Was Asperger Syndrome?
Asperger syndrome, sometimes referred to simply as “Asperger’s,” was once a commonly used term to describe individuals on the autism spectrum who did not have an accompanying intellectual disability. These individuals often had strong language skills but experienced significant challenges in social interaction, communication, and flexible thinking.
While the term was used for several decades, it has since been phased out of clinical use. Experts now recognize that the traits once attributed to Asperger syndrome fall within the broader category of Autism Spectrum Disorder (ASD). This shift reflects a more accurate and inclusive understanding of autism.
Why the Term Is No Longer in Use
Today, Asperger syndrome is not recognized as a standalone diagnosis. The change came as part of updates to diagnostic manuals used worldwide:
- In 2013, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) merged Asperger syndrome into Autism Spectrum Disorder.
- In 2019, the International Classification of Diseases, 11th Revision (ICD-11) followed suit, also retiring the term.
These changes were made to reflect the understanding that autism exists along a spectrum, with varying strengths and support needs, rather than as separate and distinct subcategories.
Historical Context and Controversy
The term “Asperger syndrome” was first popularized in the 1980s by Dr. Lorna Wing, a British psychiatrist and pioneer in autism research. She used the term in reference to the earlier work of Austrian pediatrician Hans Asperger, who had studied children with behavioral traits resembling what we now recognize as autism.
While Dr. Wing’s efforts contributed significantly to our modern understanding of autism as a spectrum, later revelations about Hans Asperger himself have led to the term becoming controversial. Historical investigations have shown that Asperger was complicit with the Nazi regime during World War II. He played a role in identifying children he deemed less socially valuable, some of whom were sent to clinics where they were ultimately killed under the Nazi euthanasia program.
Although there was once debate about Asperger’s intentions and awareness, recent scholarship has made it clear that he knowingly contributed to these atrocities. This knowledge has further supported the move away from using his name in association with autism.
Identity and Terminology
Some individuals who were diagnosed with Asperger syndrome before the term was retired continue to use it to describe themselves. For many, the diagnosis formed a meaningful part of their personal identity and helped them better understand their experiences.
While it’s important to honor how individuals choose to identify, it’s equally vital to understand the clinical and historical reasons for moving away from the term. Autism Spectrum Disorder is now the accepted terminology and offers a more accurate, inclusive framework for support and understanding.
Moving Forward with Inclusive Language
The retirement of the term Asperger syndrome marks an important shift toward more inclusive, respectful, and evidence-based approaches to autism. It also highlights the importance of language in shaping how we understand and support neurodivergent individuals.
By embracing the spectrum model of autism, clinicians, educators, and communities can better recognize the diverse strengths and needs of autistic people, without relying on outdated or problematic labels.
Final Thoughts
Although Asperger syndrome is no longer used in clinical settings, its history remains a part of the evolution of autism research and advocacy. Understanding why the term was retired helps promote a more compassionate and accurate view of autism, grounded in both science and social responsibility.
Choosing inclusive, modern terminology is a meaningful way to respect the dignity of autistic individuals and support a better-informed future for autism awareness.
