Dementia affects millions of individuals globally, and prevention remains paramount. A recent systematic review which evaluated the relationship between environmental factors and cognitive decline revealed air pollutants, including particulate matters and nitrogen oxides, increase the risk of dementia, in addition to accelerating cognitive decline1. Notably, individuals living near enhanced walkable and accessible local amenities showed better cognitive health compared to those who lived near major roads. These findings underscore the correlation between the environment and dementia risk, as well as the importance of designing an urbanized living that promotes cognitive well-being of individuals.
