A recent study from University College London suggests that financial difficulties may accelerate brain aging, especially in men. The research analyzed information from 2,759 individuals participating in the 1946 British cohort study. Participants were identified as having persistent low income if they were in the bottom 20% at least twice, affecting about one in six people in the study. Challenges included struggling to cope with their income or facing difficulty paying bills.
Individuals who encountered ongoing financial hardships or poverty in their early and middle adulthood exhibited poorer performance on cognitive assessments at age 53. Among those who underwent brain scans, the analysis revealed that individuals with lower incomes had inferior brain health by 69 to 71, with a more pronounced impact observed in men.
Researchers propose that financial struggles may impose chronic stress on the cognitive processing systems. Professor Praveetha Patalay, the study’s author from UCL, highlighted the importance of supporting individuals facing financial hardship to potentially prevent cognitive decline and dementia cases in the future.
The study also suggests that financial troubles in adulthood could occupy cognitive “bandwidth” related to functions like attention and decision-making. Data on financial adversity was gathered from the MRC National Survey of Health and Development, assessing household income at ages 26, 43, and 53.
Men who experienced a disadvantaged childhood and continued to face financial challenges as adults were at the highest risk of accelerated brain aging. The study, published in the journal Innovations in Aging, emphasized the necessity of aiding vulnerable households amid the current cost-of-living crisis.
Dr. Jacques Wels, from UCL’s unit for lifelong health and aging, noted the significance of examining financial hardship over several decades, indicating that prolonged adversity is linked to adverse cognitive health outcomes rather than occasional difficulties.
Commenting on the study, Dr. Richard Oakley, associate director at the Alzheimer’s Society, emphasized the broader societal and economic implications of dementia. He underscored the potential for addressing modifiable risk factors to delay or prevent around 45% of dementia cases globally, emphasizing the importance of promoting healthier lifestyles and mitigating disparities that impact brain health.
Despite dementia being a significant health concern, there is a need for greater public health attention and access to necessary support post-diagnosis to reduce its impact on the population.
