A study involving 2830 older adults found that greater neighborhood disadvantage, exposure to air pollution, higher homicide rates, and reduced greenspace are associated with an increased risk for mild cognitive impairment (MCI). Factors such as the Area Deprivation Index (ADI), fine particulate matter exposure, homicide rates, greenspace, and schooling location were linked to MCI. The study highlights the importance of considering social and environmental factors in assessing cognitive impairment risks in older adults. The findings were published in the Journal of the American Geriatrics Society. Limitations include the lack of data on all potential factors and the cross-sectional design of the study.
