Chronic money worries may quietly accelerate the ageing of the brain, according to new research from University College London. The study, which analysed data from 2,759 participants in the United Kingdom, found that by age 53, people who had experienced sustained financial hardship performed worse on cognitive tests than those who had not faced such difficulties.
“The accumulation of hardship over many years is linked to the worst cognitive health outcomes, rather than occasional episodes of adversity,” said Jacques Wels, a researcher at UCL and lead author of the study. The findings, published in the Journal of Epidemiology & Community Health, show that participants who endured persistent low income or money struggles from early to middle adulthood not only scored lower on cognitive assessments at 53 but also exhibited significant brain atrophy by age 71.
How financial stress reshapes the brain
The researchers observed that verbal memory decline slowed between ages 53 and 69 among those with chronic financial stress, suggesting that substantial cognitive losses had already occurred by midlife. The authors attribute this to financial adversity increasing cognitive load, which reduces the bandwidth available for attention and decision-making. “Persistent experience of financial adversity in adulthood may place chronic stress on the systems involved in cognitive processing and lead to cognitive impairments over time,” they wrote.
The impact was notably more severe for men, individuals from disadvantaged childhoods, and those carrying a genetic risk factor for Alzheimer’s disease. This aligns with broader research into how longer lives are not necessarily healthier years, a trend that disproportionately affects vulnerable populations.
Implications for dementia prevention
Dementia currently affects 57 million people globally, with cases projected to triple to over 150 million by 2050. The study underscores the importance of identifying modifiable factors that can slow cognitive decline. Given the ongoing cost-of-living crisis across Europe, where record numbers of households report financial hardship, the findings carry particular urgency.
“Supporting people facing financial hardship and reducing chronic poverty could also help prevent cognitive decline and dementia cases in the future,” said Praveetha Patalay, senior author of the study. The researchers argue that preventing financial adversity from becoming chronic could be a key strategy in protecting against age-related cognitive impairments.
The study adds to a growing body of evidence linking socioeconomic factors to brain health. For instance, traffic noise has been linked to higher Parkinson's risk, highlighting how environmental and economic stressors interact with neurological outcomes. Similarly, heat, not rainfall shortage, now drives Europe's droughts, a shift that may exacerbate economic pressures on vulnerable communities.
While the study is observational and cannot prove causation, its robust longitudinal design—tracking participants over decades—strengthens the case for policy interventions. As European governments grapple with rising living costs, these findings suggest that addressing chronic poverty may yield benefits far beyond economic stability, potentially safeguarding cognitive health across the continent.
