Ambient air pollution exposures increase risk for Alzheimer's disease (AD) and related dementias, possibly due to structural changes in the medial temporal lobe (MTL). However, previous MRI studies examining exposure effects on the MTL were cross-sectional and mostly focused on the hippocampus, yielding mixed results. We addressed these limitations using longitudinal data collected from 653 cognitively unimpaired community-dwelling women from the Women's Health Initiative Memory Study with two MRI scans (M Show less
