Not only does long-term financial hardship strain wallets, it physically shrinks brains. This study found that persistent low income accelerates brain atrophy and tanks memory and processing speed by midlife. Prolonged poverty, not just a rough patch, is a direct threat to cognitive health, and policies that reduce chronic financial stress could cut future dementia rates.
The claim that poverty uniquely destroys cognitive function doesn't hold up under scrutiny. A reanalysis of key research found that when income data isn't artificially split into categories, the supposed link between financial worry and impaired cognition falls apart. Financial stress affects people across income levels; the poverty-brain ageing narrative is built on shaky methodology.
