Recent studies have highlighted the potential link between air quality and cognitive decline in older adults. As air pollution levels rise globally, concerns about its effects on human health, particularly brain health, have become more pressing. Cognitive decline, including conditions such as dementia and Alzheimer's disease, is a major concern for aging populations. This article reviews the current literature on the effects of air quality on cognitive function in older adults, focusing on how exposure to pollutants such as particulate matter (PM), nitrogen dioxide (NO2), and sulfur dioxide (SO2) may contribute to neurological deterioration. The evidence suggests that long-term exposure to poor air quality accelerates cognitive decline and may increase the risk of developing neurodegenerative diseases. This article also discusses potential mechanisms, risk factors, and the need for policy interventions to mitigate exposure to air pollution in older populations.
