What autism subtype was abandoned in the DSM-5?

• A. Asperger Syndrome
• B. Pervasive Developmental Disorder not Otherwise Specified
• C. Childhood Disintegrative Disorder
• D. Autistic Disorder

Answer: (B)

The autism subtype that was abandoned in the DSM-5 is Asperger Syndrome. In the transition from DSM-IV to DSM-5, the previously distinct categories such as Asperger Syndrome, Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS), and Autistic Disorder were all merged into a single umbrella diagnosis known as Autism Spectrum Disorder (ASD).

The reason for this change was to provide a more consistent and clear understanding of autism, as individuals with these various diagnoses exhibited overlapping characteristics and behaviors. By consolidating them into one category, the DSM-5 aims to improve the diagnostic process and ensure that individuals receive appropriate support and interventions based on their needs, regardless of where they might have previously been classified.

The old categories were seen as too rigid and inadequate in capturing the complexity and variability of how autism usually presents in individuals, leading to the decision to utilize a spectrum model that reflects a range of symptoms and levels of functioning.
