Short-Term Exposure to Air Pollution May Impede Cognition; Aspirin Could Help

Exposure to air pollution, even over the course of just a few weeks, can impede mental performance, according to a new study led by researchers at Columbia University Mailman School of Public Health.

Exposure to air pollution, even over the course of just a few weeks, can impede mental performance, according to a new study led by researchers at Columbia University Mailman School of Public Health. However, these adverse effects were lessened in people taking nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin. The study is among the first to explore short-term air pollution exposures and the use of NSAIDs to mitigate their effects. The results are published in the journal Nature Aging.

Examples of events that would increase someone’s exposure to air pollution over the short term could include forest fires, smog, second-hand cigarette smoke, charcoal grills, and gridlock traffic.

The researchers examined the relationship between exposures to fine particulate matter (PM2.5) and black carbon, a component of PM, and cognitive performance in 954 older white males from the Greater Boston Area enrolled in the Normative Aging Study. They also explored whether taking NSAIDs could modify their relationships. Cognitive performance was assessed using the Global Cognitive Function (GCF) and Mini-Mental State Examination (MMSE) scales. Air pollution levels were obtained from a site in Boston.
