Persistent financial struggles have been linked to faster brain ageing, a new study has revealed. The study found that there was a pronounced impact on men, individuals from disadvantaged childhoods and those with a greater genetic risk of Alzheimer's disease. Researchers suggest that supporting those facing financial hardship and reducing poverty could be crucial in preventing future dementia cases. And among people who had brain scans, analysis showed those who had lower incomes had worse brain health by 69 to 71. Those facing persistent financial problems in adulthood may place chronic stress on the systems involved in cognitive processing, leading to impairments over time.
