Summary: A 16-year longitudinal study of more than 10,000 adults aged 50 and over shows a consistent association between higher psychological wellbeing and stronger memory performance in middle and later life. Participants who reported greater life satisfaction, autonomy and purpose were more likely to score higher on episodic memory tests across the study period.
These results remained after accounting for depressive symptoms, indicating that wellbeing has a distinct relationship with cognitive health. The findings add to growing evidence that mental and emotional wellbeing may help protect memory and delay age-related cognitive decline.
Key facts
- Long-term association: Higher self-reported wellbeing predicted better memory scores across 16 years of follow-up.
- Independent of depression: The wellbeing–memory link persisted even after adjusting for depressive symptoms.
- Potentially protective: Supporting psychological wellbeing could be one component of strategies to preserve memory with aging.

Higher levels of wellbeing may help reduce the risk of memory loss in middle age, according to new research that followed more than 10,000 adults over 16 years.
Published in the peer-reviewed journal Aging & Mental Health, the study examined repeated measures of psychological wellbeing and episodic memory among participants drawn from a long-running UK cohort. Those who reported greater satisfaction with life, feelings of control and opportunities for self-realisation tended to perform better on memory tests over time.
All participants included in the analysis were free of diagnosed dementia at the start of the study. In addition to higher life satisfaction, those with greater wellbeing reported stronger senses of autonomy, independence and control over their daily lives.
The observed association was small but statistically significant. Importantly, the link between wellbeing and later memory performance held after researchers adjusted for depressive symptoms, suggesting wellbeing contributes to cognitive outcomes beyond the effects of depression.
The research team — composed of experts across the UK, US and Spain — found no strong evidence that better memory predicted later improvements in wellbeing. The authors note, however, that this lack of bidirectional evidence does not entirely rule out the possibility that declining wellbeing might signal early, preclinical cognitive changes.
The authors suggest these findings underline the influence of psychosocial factors on brain health. Interventions that foster psychological wellbeing, such as mindfulness, social engagement, or programs that support a sense of purpose and control, may help maintain cognitive functions like memory as people age.
Lead author Dr Amber John, a Lecturer in Psychology at the University of Liverpool and an Alzheimer’s Research UK Fellow, emphasises the public health importance of the findings: “In the context of an ageing population, understanding factors that may protect and maintain healthy cognitive function is critical for population health and for informing health policy.”
“While our study can’t establish causality, the pattern of results suggests that higher wellbeing tends to precede better memory performance rather than the other way around,” Dr John added. “If future research confirms a causal effect, improving wellbeing could be a modifiable way to help protect memory.”
Co-author Professor Joshua Stott of UCL notes that the study advances understanding of how self-rated wellbeing and memory relate over time and highlights the need to consider psychosocial influences in research on brain ageing.
Depression and anxiety are already recognised risk factors for accelerated cognitive decline and dementia. Wellbeing in this study was measured as emotional health combined with effective functioning — including happiness, confidence, a sense of purpose and perceived control over life.
Previous studies have linked wellbeing to slower age-related declines in certain cognitive processes, but most examined only one direction of association. This study aimed to provide longer-term, bidirectional analysis in people without substantial cognitive impairment at baseline.
Data came from 10,760 men and women participating in the English Longitudinal Study of Ageing (ELSA), a nationally representative cohort of UK adults over 50. Participants completed wellbeing and memory assessments every two years, for a total of nine assessments across the 16-year period beginning in 2002.
Memory was measured using a learning task that required immediate and delayed recall of a list of ten words. Wellbeing was assessed with a quality-of-life questionnaire that captured satisfaction across domains such as pleasure, control, autonomy and self-realisation, using items like “I can do the things that I want to do” and “I feel that life is full of opportunities.”
Analyses excluded individuals with a dementia diagnosis at baseline. Results showed small but consistent associations: higher wellbeing predicted higher immediate and delayed recall scores across multiple timepoints, and these associations remained after accounting for depressive symptoms.
The authors discuss plausible mechanisms linking wellbeing to memory, including biological pathways (for example cardiovascular health), lifestyle behaviors (physical activity and social engagement), and socioeconomic factors. Age, sex, lifestyle and socioeconomic status may influence the strength of the wellbeing–memory relationship.
Although the study did not find clear evidence that better memory leads to later improvements in wellbeing, the researchers acknowledge that lower psychological wellbeing could also be an early indicator of emerging cognitive impairment before clinical symptoms become apparent.
Funding for the research came from Alzheimer’s Research UK, the Medical Research Council (UKRI), the US National Institute on Aging, and the UK’s National Institute for Health and Care Research (NIHR).
Emma Taylor, Information Services Manager at Alzheimer’s Research UK, said the findings support public health messages about maintaining heart health, staying mentally active and keeping socially connected as ways to support brain health with age. She added that while this observational study cannot prove causation, it reinforces the importance of mental wellbeing as one piece of a broader strategy to reduce dementia risk.
Like all long-term cohort studies, this analysis faces challenges from sample attrition over many years; however, the authors used analytic methods that made use of available observed data without discarding cases or relying on imputation.
In conclusion, the authors suggest their findings provide a foundation for additional research into interventions and factors that could enhance brain health across aging populations.
Co-author Dr Emily Willroth, Assistant Professor of Psychological & Brain Sciences at Washington University in St Louis, commented: “Future work building on these results could help inform strategies to support cognitive health as populations age.”

Original research (open access): “Wellbeing and memory function: testing bidirectional associations in the English Longitudinal Study of Ageing (ELSA)” by Amber John et al., published in Aging & Mental Health. DOI: 10.1080/13607863.2025.2468408
Abstract
Wellbeing and memory function: testing bidirectional associations in the English Longitudinal Study of Ageing (ELSA)
Objectives
This study tested bidirectional relationships between psychological wellbeing and episodic memory in a large, nationally representative sample of adults aged 50 and over.
Method
Researchers used data from ELSA, a longitudinal cohort of older adults. After excluding participants with dementia at baseline, repeated measures of wellbeing (CASP-19) and episodic memory (immediate and delayed recall of a word list) were available nine times over 16 years. Cross-lagged models were applied to assess bidirectional associations between wellbeing and memory.
Results
Higher wellbeing consistently predicted higher subsequent immediate and delayed memory scores across time points, with small effect sizes (standardised betas approximately 0.04–0.07). There was no strong evidence that higher memory scores predicted later increases in wellbeing.
Conclusion
Higher psychological wellbeing is associated with better memory function over 16 years. The study did not find evidence that memory drives later wellbeing in this sample, which may indicate that such relationships emerge only after clinically meaningful cognitive impairment develops. Better wellbeing may therefore represent a protective factor for maintaining memory from middle to later adulthood.
