Study links air pollution to potential dementia risk, suggesting cleaner air improves brain health in older adults.

Researchers from Taiwan's Yang Ming Chiao Tung University found that air pollution may harm brain health in older adults, potentially leading to dementia. The study of 412 people over 60 from various air quality areas showed that cleaner air correlated with better brain structure and cognitive function. The team suggests that reducing pollution could improve brain health and delay dementia risk.
