Commentary: Time to reconceptualize ASD? comments on Happe and Frith (2020) and Sonuga-Barke (2020)

Area of Science:

• Neurodevelopmental disorders
• Psychiatric nosology
• Autism spectrum disorder (ASD) research

Background:

• Autism has been a focus of clinical concern and research since the 1980s.
• Significant conceptual changes in understanding autism have been documented.
• A debate exists regarding the implications of these changes for psychiatric classification.

Purpose of the Study:

• To discuss the conclusion that a Kuhnian revolution in psychiatric nosology is not imminent for ASD.
• To call for a re-evaluation of a paradigm shift in ASD nosology among researchers.

Main Methods:

• Commentary on existing research and conclusions by Happe and Frith (2020) and Sonuga-Barke (2020).
• Analysis of the concept of paradigm shift in the context of autism spectrum disorder.
• Literature review and critical discussion of nosological changes in autism.

Main Results:

• Seven key changes in the concept of autism since the 1980s have been identified.
• Despite these changes, consensus on a fundamental paradigm shift in ASD classification is lacking.
• The commentary critically examines the resistance to a Kuhnian revolution in ASD nosology.

Conclusions:

• The commentary argues for a re-evaluation of the benefits of a paradigm shift in ASD nosology.
• Researchers are urged to consider the implications of ongoing conceptual changes for classification systems.
• The need for a potential redefinition of autism spectrum disorder classification is highlighted.
