A recent study highlights a concerning link between persistent financial hardship and cognitive decline, as well as signs of accelerated brain aging, in adults. Researchers from University College London examined 2,759 participants from the UK’s MRC National Survey of Health and Development, which started in 1946.
According to their findings, adults facing continuous financial difficulty or low income struggled more with cognitive tests targeting verbal memory and processing speed. Moreover, MRI scans indicated poorer brain health, evidenced by indicators such as brain shrinkage and enlarged ventricles.
Dr. Jacques Wels, from UCL’s Unit for Lifelong Health & Ageing, explained, “We know cognitive decline ties to genetic risks and adverse childhood experiences, but the impact of lifelong financial hardship was less understood.” The study asserts that the accumulation of poverty significantly associates with cognitive decline.
The results were particularly pronounced in men, individuals from disadvantaged backgrounds, and carriers of the APOE-ε4 genetic variant, which raises Alzheimer’s disease risk. “Cognitive decline stems from genetic risks and behaviors, but lifelong experiences, often beyond personal control, play a role too,” Wels noted.
Chronic financial adversity is suggested to accelerate cognitive aging more than short-term hardships, potentially due to stress-induced inflammation or the mental strain of ongoing financial concerns. However, the study is observational and doesn’t definitively pin financial stress as the causal factor for cognitive issues.
Dr. Wels emphasized that the cohort, born in 1946, experienced life within specific historical contexts, noting its stronger effects on men, possibly due to the traditional ‘breadwinner’ role in past generations.
While reducing long-term poverty could safeguard brain health, further research is necessary to confirm whether better financial conditions directly impact reducing dementia and cognitive decline risks.
