Air pollution linked to gray matter atrophy and increased risk of Alzheimer’s disease in older women


  • Exposure to air pollution in later life may increase the risk of Alzheimer’s disease in women.

Why this matters

    It has been suggested that air pollution is linked to dementia either through neurodegenerative processes or increased cerebrovascular damage. These novel findings have important public health and regulatory implications because they suggest that late-life exposure to ambient PM2.5 increases the neuroanatomical risk of Alzheimer’s disease.
