Study Links Financial Hardship to Cognitive Decline and Brain Changes

A study conducted over 70 years in Britain found that adults who experienced repeated financial hardship scored lower on memory and processing speed tests by age 53. Later brain scans indicated that those with a history of persistent low income had larger fluid-filled spaces in the brain, suggesting tissue shrinkage. The research, published in the journal Innovation in Aging, analyzed data from the 1946 British birth cohort, tracking nearly 3,000 individuals from birth into their 70s. The study identified that financial stress could be a modifiable factor for long-term brain health, although it does not establish a direct cause-and-effect relationship. Specific subgroups, including men and individuals carrying the APOE-ε4 Alzheimer’s risk gene, showed more pronounced brain changes, but these findings are preliminary. The study tracked financial hardship through income levels and self-reported struggles to meet basic needs at various life stages.
