Aarhus: Researchers from Aarhus University, Denmark, and the University of Florida have found that long-term exposure to air pollution may increase the risk of developing certain forms of dementia.

According to Anadolu Agency, the study highlights pollutants that are encountered by most people daily, linking prolonged exposure to fine air particles and nitrogen dioxide with a higher risk of Lewy body disease and Parkinson's-related dementia. Dimitry S. Davydow, a psychiatrist and professor, emphasized the widespread nature of these pollutants in a statement released by Aarhus University Hospital.

Researchers analyzed anonymized data from over 2 million individuals in Denmark, aged between 65 and 95. The study assessed air pollution levels at participants' home addresses over a decade before any dementia diagnoses were made. It specifically associated pollution from shipping, road traffic, and combustion sources with increased dementia risks.

The study noted some limitations, such as the lack of data on lifestyle factors like smoking habits. Jakob Christensen, chief physician at Aarhus University Hospital, remarked that the findings suggest air pollution could be a contributing environmental factor in the development of these diseases.
