A recent large-scale study has revealed that prolonged exposure to fine particle air pollution and smog can significantly increase the risk of Alzheimer’s disease, highlighting potential health concerns for residents of Lahore.
The research, conducted by scientists at Emory University and published in PLOS Medicine, analyzed health records of nearly 28 million people over almost two decades. The study examined the indirect ways in which air pollution can affect the brain, particularly through cardiovascular conditions such as high blood pressure, stroke, and depression — all of which are associated with dementia and cognitive decline.
Air Pollution and Brain Health
Researchers found that long-term exposure to airborne fine particulate matter, commonly present in smog-heavy urban centers, contributes to neuroinflammation and vascular stress, both of which can accelerate cognitive decline. The findings suggest that residents of cities like Lahore, where pollution levels frequently exceed safe limits, may face heightened vulnerability to Alzheimer’s and other forms of dementia.
Implications for Public Health
The study underscores the urgent need for stricter air quality regulations and public health interventions in Pakistan’s major urban centers. Reducing emissions from traffic, industrial activity, and other pollution sources could help lower the population’s long-term risk of neurodegenerative diseases.
Experts also recommend lifestyle measures for individuals, including regular cardiovascular health monitoring, a balanced diet, and limiting exposure to heavy smog days through masks or indoor air filtration.
The research adds to growing evidence that environmental factors, particularly air quality, play a crucial role in long-term cognitive health, reinforcing the importance of addressing pollution as a national health priority.
