Neurodivergence as environmental adaptation

Abstract

Apparent increases in autism and other forms of neurodivergence are often interpreted as a rise in incidence. Yet demographic expansion, diagnostic broadening, and growing cultural awareness all contribute to higher prevalence estimates. At the same time, contemporary sensory and digital environments have become increasingly overstimulating, characterized by persistent noise, visual saturation, hyperconnectivity, and unpredictable social rhythms. These conditions heighten sensory and cognitive load for many individuals, making neurodivergent traits more visible and increasing the urgency of diagnosis. Drawing on cognitive ecology, sensory neuroscience, and neuroaffirmative scholarship, this perspective proposes that neurodivergence can be understood as an adaptive response to environments that exceed nervous-system thresholds. Autistic regulatory behaviors-including withdrawal, shutdown, sensory avoidance, and monotropism-driven focus-may serve as mechanisms for maintaining coherence in overstimulating contexts. Interpreting neurodivergence as an ecological signal offers new pathways for public health, accessibility design, and social policy. It reframes autistic embodiment not as internal dysfunction but as meaningful information about the livability of contemporary environments.
