A new study has suggested that worsening financial conditions may speed up cognitive ageing in middle-aged and older adults. Researchers say that a person’s financial wellbeing could play a significant role in how their brain ages over time.
Experts from the Columbia University Mailman School of Public Health found a direct connection between financial decline and memory loss. According to their findings, significant financial deterioration is associated with memory decline equivalent to about five extra months of ageing per year.
The study, published in the American Journal of Epidemiology, revealed that both lower financial wellbeing and worsening financial conditions were consistently linked to poorer memory and faster cognitive decline. These effects were especially strong among adults aged 65 and older.
Lead researcher Adina Zeki Al Hazzouri explained that financial wellbeing is an important and emerging factor influencing overall health, including brain function. She noted that prolonged financial stress can overwhelm mental capacity and contribute to negative cognitive outcomes.
The findings also suggest that providing financial support and income assistance later in life may help protect cognitive health and reduce the risk of dementia, particularly for individuals experiencing financial hardship.
For the study, the researchers had analysed data from nearly 7,700 adults aged 50 and older who participated in the Health and Retirement Study between 2010 and 2020. They examined how both long-term financial status and changes over four years affected participants’ performance on memory and cognitive tests.
Financial wellbeing was measured using an index that accounted for both psychological stress and material hardship — such as difficulty paying bills, low income, financial dissatisfaction, and limited access to basic needs. Each decline in financial wellbeing was associated with lower memory scores and faster deterioration.
Interestingly, improvements in financial status did not always lead to better cognitive outcomes.
Researchers believe financial strain may affect brain health through several pathways, including chronic stress, reduced access to healthcare and nutritious food, and fewer opportunities for social interaction.
Older adults may be particularly vulnerable, as they often rely on fixed incomes and have limited ability to recover from financial setbacks.
Overall, the study supports the idea that declining financial wellbeing in midlife and later years can accelerate cognitive ageing, highlighting the importance of financial stability for long-term brain health.
