Study Reveals Impact of Early Adversity on Coping, Mental Health, and Cognition
Author(s):
Key Takeaways
- Early adversity impacts mental health, brain structure, and cognition, with coping strategies and neuroticism playing mediating roles.
- Physical neglect affects cognitive outcomes, but no direct link to brain volume was observed.
A recent large-scale analysis presented at the 2025 AD/PD Conference highlighted the role of coping strategies in mitigating negative outcomes.

A recent study leveraging data from the UK Biobank has shed new light on how early adverse experiences influence mental health, brain structure, and cognitive function. Although prior research has established a connection between early adversity and later-life outcomes, the mechanisms driving these associations were unclear. This study sought to clarify those pathways by examining the roles of coping strategies and personality traits, particularly neuroticism.1
Researchers analyzed data from over 500,000 participants, integrating behavioral and imaging measures into a structural equation model. Presented at the 2025 International Conference on Alzheimer’s and Parkinson’s Disease (AD/PD), held April 1-5 in Vienna, Austria, the findings suggested that the effects of early adversity vary depending on the specific type of adversity experienced. Notably, only physical neglect was linked to cognitive outcomes, whereas no direct association was observed between early adversity and brain volume. However, the study identified significant mediation effects through coping strategies.
Conducted by lead author Morgane Künzi, PhD, postdoctoral researcher at the Dementias Platform UK (DPUK) in the Department of Psychiatry at the University of Oxford, and colleagues, the findings underscored the potential for targeted interventions aimed at improving coping mechanisms to mitigate the long-term impact of early adversity. The results aligned with existing literature and suggested that fostering adaptive coping strategies could support cognitive and mental health resilience, ultimately promoting healthy brain aging.
Another recent study further underscored the long-term consequences of childhood abuse and deprivation on cognitive and health outcomes. Analyzing data from 2 large UK cohorts—the English Longitudinal Study of Ageing (ELSA) and the UK Biobank—researchers reported that early adversity was broadly associated with poorer physical and mental health, lifestyle choices, and cognitive function in later life.2

Published in BMC Public Health, the study identified education as a significant mediator in these associations. Individuals with higher educational attainment appeared to experience less severe negative outcomes linked to early adversity, suggesting that access to education may serve as a protective factor against long-term cognitive decline and dementia risk.
Although the effects varied depending on the type of adversity and cohort studied, the findings emphasized the need for policies that promote equitable access to education and early-life support. These interventions could play a crucial role in buffering the long-term impacts of early adversity, reinforcing the broader understanding that both psychological and social factors contribute to lifelong brain health.
A recent longitudinal study also offered further insight into how childhood mental health mediates the relationship between early-life adversity and later cognitive function. Examining data from over 13,000 individuals assessed from early childhood through adolescence, researchers reported that mental health difficulties significantly contributed to poorer cognitive performance over time, particularly in working memory and vocabulary development.3
Published in the Journal of Child Psychology and Psychiatry, the study revealed that mental health challenges accounted for a substantial proportion of the observed cognitive deficits, with mediation effects of 59% for working memory and 70% for vocabulary. Notably, mental health difficulties persisted throughout childhood, compounding the impact of early adversity on cognitive outcomes.
These findings underscored the critical role of early mental health support in fostering cognitive resilience. By identifying and addressing psychological challenges in vulnerable children, targeted interventions could help mitigate the long-term cognitive consequences of early adversity, reinforcing the importance of integrating mental health support into educational and clinical settings.
