Long-term air pollution and traffic noise exposures and mild cognitive impairment in older adults: A cross-sectional analysis of the Heinz Nixdorf Recall Study

Mild cognitive impairment (MCI) describes the intermediate state between normal cognitive aging and dementia. Adverse effects of air pollution (AP) on cognitive functions have been proposed, but investigations of the simultaneous exposure to noise are scarce. The objective of the study was to analyze the cross-sectional associations of long-term exposure to AP and traffic noise with overall MCI, amnestic (aMCI) and non-amnestic (naMCI) MCI.
