Understanding aging and neurodevelopmental change in autistic adults: Language and cognition at the crossroads

The study of aging in adults with autism, particularly in relation to language and cognitive challenges, represents a rapidly evolving field within neurodevelopmental and gerontological research. While much effort has been devoted to understanding autism spectrum disorder (ASD) in childhood, there is a notable lack of comprehensive research that tracks the experiences of autistic individuals as they age. Key questions remain about how typical aging processes interact with lifelong neurodevelopmental conditions, including issues such as the trajectory of language skills, changes in cognitive abilities, and the impact of co-occurring medical conditions. Recent studies suggest that autistic adults might experience aging differently than neurotypical peers, with possible variations in cognitive decline, language processing, and social communication. However, much of the existing work is cross-sectional and lacks longitudinal depth, making it challenging to fully capture the nuanced interplay between aging, autism, language, and cognition.Recent advances in longitudinal study designs, neuroimaging, and behavioral science have begun to shed light on the cognitive and communicative aging process within autistic populations. Findings suggest diverse outcomes; some autistic adults maintain stable cognitive and language abilities over time, while others encounter increased difficulties, potentially compounded by age-related health challenges. The heterogeneity of autism itself complicates generalizations, and factors such as support networks, early interventions, and co-morbid conditions influence outcomes substantially. Despite these efforts, major gaps persist in our understanding of mechanisms underlying decline or resilience, culturally informed differences, and the role of social environments.This Research Topic aims to synthesize the latest evidence on the intersection of autism and aging, with a primary focus on challenges related to language and cognition in adults. Key objectives include elucidating the developmental trajectories of cognitive and communicative functions, identifying risk and protective factors for decline or preservation, and exploring the lived experiences and needs of older autistic adults. Critical questions involve how neurodevelopmental and neurodegenerative processes interact, which aspects of cognition and language are most affected, and what interventions or supports may bolster quality of life across the lifespan.To gather further insights into how aging uniquely impacts language and cognition in autistic adults, we welcome articles addressing, but not limited to, the following themes:• Longitudinal and cross-sectional analyses of language and cognitive trajectories• Interactions between neurodevelopmental and neurodegenerative changes in autism• Impact of co-occurring conditions on aging outcomes in autistic adults• Role of social, cultural, and environmental factors in shaping cognitive and communicative aging• Interventions and supports targeting language and cognitive decline• Lived experiences, healthcare access, and quality of life in older autistic adults• Methodological advances and challenges in research on autism and aging Topic editors: Joseph C.Y.
