Toward an Emergent Paradigm for Neurodiversity and Health

Abstract

Autism research has developed through multiple paradigms. Medical models locate difficulty within individual neurology, while social and neurodiversity models emphasize environmental barriers and the legitimacy of cognitive variation. Biopsychosocial and hybrid approaches integrate these perspectives, recognizing that biological, psychological, and social factors all matter. Yet these frameworks remain largely descriptive and offer limited accounts of how these domains dynamically interact across development to produce the wide heterogeneity observed in autistic experience and adult outcomes. This paper introduces the Evolutionary Stress Framework (ESF), a complexity-based model that reframes neurodevelopmental variation as the emergent outcome of stress–energy regulation and predictive processing over time. Drawing on stress physiology, adaptive calibration theory, predictive processing, and disability scholarship, we review traditional medical, social, biopsychosocial, and hybrid models; examine the contributions and limits of the neurodiversity paradigm; and articulate ESF’s core constructs: emergent neurotypes, stress incoherence, and emergent allostasis. Within ESF, autistic traits function as coherent, context-dependent stress–energy strategies rather than separable strengths and deficits. ESF conceptualizes pathology not as deviation from a normative baseline but as stress incoherence—states in which long-standing calibrations become unsustainable under current environmental conditions. This framework helps explain heterogeneity, developmental change, the clustering of physical and mental health conditions, and the disproportionate burden of burnout and health disparities observed in autistic adulthood. ESF shifts intervention targets from trait suppression to environmental design, co-regulation, and individualized support organized around bio-neurotype–specific regulatory needs. We outline implications for research, clinical practice, and policy and identify directions for empirically operationalizing ESF constructs.

Community Brief: A New Paradigm for Understanding Autism

What is the purpose of this article?

This article introduces the Evolutionary Stress Framework (ESF), a way of understanding autism that integrates insights from medical, social, and neurodiversity models. ESF is not a new diagnosis or a replacement for existing paradigms. Instead, it explains ways in which autistic traits develop and why experiences vary so widely across people and life stages.

What is already known about this topic?

Understanding autism has been difficult because existing models each describe only part of the picture. Medical models focus on biology; social and neurodiversity models emphasize environment and acceptance. Biopsychosocial and hybrid approaches integrate these perspectives but remain largely descriptive. None fully explains why autistic people can thrive in some settings and struggle in others, or why health problems and burnout are so common in adulthood.

What personal or professional perspectives do the authors bring to this topic?

The lead author is an autistic researcher whose perspectives are shaped by lived experience of autistic adulthood, long-term engagement with neurodivergent communities, and interdisciplinary work across stress physiology, complexity science, and disability studies.

Why is this important?

Autistic adults face significant health disparities, including higher rates of burnout, mental health challenges, and early mortality. These outcomes are not inevitable features of being autistic; they reflect what happens when environments consistently fail to support autistic ways of regulating. ESF provides a framework for understanding these patterns and identifying where change is needed.

What do the authors recommend?

ESF shifts the focus from “fixing the person” to shaping environments that support regulation. It highlights the importance of predictability, sensory design, communication flexibility, and shared responsibility for co-regulation, not just accommodations placed on individuals.

ESF does not claim that autistic traits are always adaptive or always impairing. Instead, it shows how traits, challenges, and health outcomes emerge from the interaction of biology and environment over time.

How will these recommendations help autistic adults now or in the future?

These recommendations shift the focus of support from trying to change autistic behavior to improving the environments and systems autistic people live within. When environments are predictable, sensory demands are manageable, and support adapts to changing energy levels, autistic adults are less likely to experience burnout, loss of functioning, or chronic health strain. Recognizing autism as a dynamic developmental profile rather than a fixed deficit also encourages flexible support across the lifespan, allowing services to adjust as needs change. This perspective leads to several practical principles:

Autism is not a static diagnosis; it is an emergent, stress-shaped profile.

Reducing environmental mismatch may be more effective than behavioral control.

Well-being must be defined with, not for, autistic people.

Support must be dynamic and individualized over the lifespan.

Neurodiversity is a foundational feature of resilient communities, but only when supported by responsive infrastructure.

The goal is to build systems that allow autistic adults to regulate their environments, sustain their energy, and participate in society on their own terms.
