Aspergers vs Autism: What’s the Difference?

Autism is often misunderstood, especially when it comes to its historical differentiation between Asperger’s syndrome and autism. Asperger’s was initially considered its own distinct diagnosis, but in 2013, the DSM-5 merged it with the broader category of autism.

This blog discusses Aspergers vs Autism, the key differences, and how the diagnosis has evolved over time.

The History of the Autism Spectrum and Aspergers

What is Asperger’s Syndrome?

Asperger’s Syndrome was first identified in the 1940s by Hans Asperger. It was included in the DSM-IV as a separate diagnosis until 2013, when it was merged under the umbrella of F84.0 Autism Spectrum Disorder (ASD) in the DSM-5. The shift from a separate diagnosis to including it within autism spectrum disorders has sparked ongoing debate.

Despite being removed as a diagnosis in the DSM, some autistic adults continue to identify with the term Asperger’s due to personal significance. Many in the autistic community still use it as part of their self-identity, and that’s completely valid.

What is the Difference between Aspergers and Autism Spectrum Disorder?

Before the DSM-5 revision in 2013, Asperger’s was often referred to as “high-functioning autism” due to its similarity to autism, but with no language delays or cognitive impairment. However, there are four main differences between Asperger’s and autism as originally defined in the DSM-IV.

Differences between Aspergers and Autism Spectrum Disorder (DSM-IV)

• Absence of a delay in language development
• No significant cognitive delay
• No requirement for symptom onset prior to age 3
• Autism spectrum disorder includes a broader range of “symptoms”, including communication challenges

While Asperger’s was once considered “less severe” than autism, the classification led to misunderstanding.

Instead of labeling autism as “high functioning” or “low functioning”, the modern understanding of autism focuses on support needs rather than a hierarchy of severity.

How Autism Diagnoses Have Evolved Over Time

Historically, autism was seen only in terms of more obvious developmental delays. However, Autism Spectrum Disorder in the DSM-5-TR now covers a wider spectrum, including a variety of support levels. The current DSM classification categorizes autism into three levels of support needs rather than using outdated labels like “high-functioning” or “low-functioning.”

Since the merger of the autism spectrum and Aspergers, the autistic community has continued to advocate for more nuanced and individualized diagnoses that don’t rely on “functioning labels” but instead focus on support needs and individual characteristics.

Why the Aspergers vs Autism Debate Still Matters

While the DSM-5 no longer uses Asperger’s as a distinct diagnosis, the discussion about the autism spectrum and Aspergers still holds weight within the autistic community. Many people with Asperger’s feel a strong connection to the term, and for them, it represents a significant part of their identity. Others have embraced the term “autistic” and prefer the broader, inclusive label it offers.

The core takeaway is that both terms describe individuals with autism who have unique challenges, including social difficulties, sensory sensitivities, and communication differences. However, the nuances of these traits and the support needs vary greatly from person to person, regardless of the label used.

Understanding Your Own Neurodivergent Identity

Whether you identify as autistic, Asperger’s, or another neurodivergent trait, exploring your identity is an important step toward self-understanding. If you’re considering whether you might be on the autism spectrum or wondering about past diagnoses, know that the autistic community offers a wealth of resources and guidance.

Self-diagnosis or informal exploration can be a powerful tool for understanding neurodivergent identity. Autism assessments can also be valuable for those seeking validation, a deeper understanding of their traits, or access to the resources that suit their needs.

How to Determine if You’re Autistic

Curious if you fall on the autism spectrum? Think about the traits of autism. Do any of these resonate with you?

Traits to Consider

• Difficulty with social interaction: You may find it hard to understand social cues or engage in conversations naturally.
• Sensory sensitivities: Lights, sounds, or textures may feel overwhelming.
• Repetitive behaviors: Engaging in repetitive tasks or routines may feel comforting or help you focus.
• Need for predictability: Struggling with sudden changes or disruptions to routines.

If these traits sound familiar, an autism evaluation may help clarify a diagnosis and connect you with resources that support your unique neurotype.

Key Takeaways

1. Aspergers vs Autism: While once considered separate, Asperger’s is now part of the broader autism spectrum.
2. Asperger syndrome is now classified as Level 1 Autism Spectrum Disorder in the DSM
3. Diagnosis evolution: The DSM-5 moved away from functioning labels, focusing instead on individual support needs.
