The transition from the DSM-IV to the DSM-5 criteria for autism spectrum disorders represents an effort to create a more unified and nuanced understanding of autism. This shift allows for a broader recognition of the diverse range of individuals who fall within the spectrum, including those who were previously diagnosed with Asperger’s Syndrome. As a result, autism therapy services have evolved to better address the needs of this expanded group of individuals.
Elimination of Asperger Syndrome and PDD-NOS and Its Impact
In the previous edition of the DSM, Asperger syndrome was considered a distinct diagnosis characterized by qualitative impairments in social interaction and repetitive behavior, interests, and activities. However, with the release of the DSM-5, the diagnosis of Asperger syndrome was eliminated, and it is now under the autism spectrum disorder umbrella.
Similarly, PDD-NOS, which encompassed individuals who did not fully meet the criteria for a specific autism spectrum disorder, was also eliminated as a separate diagnosis. This change aims to streamline the diagnostic criteria and promote a more unified understanding of autism spectrum disorders.
The elimination of Asperger syndrome and PDD-NOS means that individuals who previously received these diagnoses now fall under the diagnosis of autism spectrum disorder.
According to the DSM-5, individuals diagnosed with autistic disorder, Asperger’s disorder, or PDD-NOS via DSM-IV should now be given the diagnosis of autism spectrum disorder.
The diagnostic criteria for ASD in the DSM-5 emphasize persistent impairments in reciprocal social communication and social interaction, as well as restricted, repetitive patterns of behavior, interests, or activities. These symptoms must be present at an early age and negatively impact everyday functioning.
It’s important to note that ASD is now seen as a continuum, with individuals exhibiting a range of symptoms and severity levels. Some individuals may have mild symptoms, while others may have more severe symptoms that significantly affect their daily lives.
DSM-IV vs. DSM-5 Criteria
In the previous edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), the diagnostic criteria for Asperger’s included a qualitative impairment in social interaction and restricted or repetitive behavior, interests, and activities.
These impairments had to cause clinically significant impairment in social, occupational, or other important areas of functioning.
However, in the DSM-5, the specific diagnosis of Asperger’s disorder was eliminated. Instead, individuals who previously would have received a diagnosis of Asperger’s Disorder, as well as those with autistic disorder and pervasive developmental disorder not otherwise specified, are now given the diagnosis of Autism Spectrum Disorder (ASD).
The DSM-5 criteria for ASD encompass two core domains: persistent social communication deficits and social interaction, and restricted or repetitive behavior, interests, or activities. These criteria take into account the severity levels of autism, ranging from level 1 (requiring support) to level 3 (requiring very substantial support).
Reclassification of Asperger's
With the reclassification of Asperger’s within the autism spectrum, individuals who previously identified with Asperger’s may now be diagnosed with autism spectrum disorder. This change aims to provide a more comprehensive and inclusive framework for understanding and diagnosing autism.
It’s important to note that the DSM-5 recognizes a new diagnosis called Social (Pragmatic) Communication Disorder (SCD), which falls under the category of Communication Disorders. SCD may serve as an alternative diagnosis for individuals who exhibit symptoms similar to those previously associated with Asperger’s.
SCD focuses specifically on difficulties in social communication without the presence of restricted and repetitive behaviors.

Introduction to Social Communication Disorder
SCD is a diagnostic category intended for individuals who experience deficits in the social use of language, without displaying the restricted interests or repetitive behaviors seen in autism spectrum disorders.
It is important to note that social communication disorder is not included within the autism spectrum but is instead considered a communication disorder. Individuals who meet the criteria for an autism spectrum disorder will receive that diagnosis rather than SCD.
The key difference between SCD and ASD lies in the presence of restricted, repetitive patterns of behavior, interests, or activities. While both disorders involve difficulties with social communication, ASD places equal emphasis on communication issues and repetitive behaviors. SCD, on the other hand, focuses primarily on challenges related to the social use of language and communication in naturalistic contexts.
To receive a diagnosis of SCD, an individual must exhibit a primary difficulty with pragmatics, which refers to the social use of language and communication. The diagnostic criteria for SCD include deficits in understanding and following social rules of verbal and non-verbal communication in naturalistic contexts, as well as challenges in adapting language according to the needs of the listener or situation. Difficulties in following conversational rules and storytelling may also be observed.
It is important to note that the difficulties associated with SCD impact effective communication, social participation, development of social relationships, academic achievement, and occupational performance. However, these challenges should not be attributed to low cognitive ability.
Practical Implications
The changes brought about by the DSM-5 in the classification of Asperger’s and related conditions have practical implications, particularly in terms of educational and service eligibility.
As such, it is important for parents, caregivers, and individuals with autism to understand these implications to ensure appropriate support and access to services.
This means that children who previously had an Asperger’s diagnosis can still qualify for programs and services despite the changes in medical diagnosis terminology.
It is essential for parents and caregivers to communicate with educational professionals and service providers to ensure that individuals with autism continue to receive the support they need.
It is also worth noting that while the DSM-5 has reclassified Asperger’s as part of Autism Spectrum Disorder (ASD), the International Classification of Diseases, 10th Revision (ICD-10) still maintains separate diagnostic codes for autism, Asperger Syndrome, and other developmental disorders.
Some professionals have chosen to use the ICD-10 diagnostic codes, anticipating that Medicare and most insurance companies may require their use in the near future. This approach allows for a more specific differentiation between different conditions within the autism spectrum.
However, it is important to consult with healthcare professionals and insurance providers to understand the specific requirements and implications of using ICD-10 codes.
It is important to emphasize that if a child is currently receiving Special Education services with an Asperger’s or PDD-NOS diagnosis, there is generally no need for a standard re-evaluation or reconsideration of treatments unless there are clinical or legal reasons to do so.
The focus should remain on providing appropriate support and accommodations based on the individual’s needs, regardless of the specific diagnostic label.
The Key Takeaway
Long story short, the DSM-5 has transformed the way we understand Asperger’s by placing it under the broader category of autism spectrum disorder. This change helps to recognize the unique traits and needs of each individual, offering better support and understanding.
