Air pollution, cardiovascular disease and dementia risk


  • Exposure to air pollution is associated with an increased risk of dementia; the presence of cardiovascular disease enhances this association.

Why this matters

  • Evidence concerning the link between air pollution and dementia is sparse and inconsistent.

  • Studies have identified high levels of air pollution as a risk factor for cardiovascular disease (CVD).

  • Considering the established link between cardiovascular burden and dementia it is possible that CVD plays a role in the association between air pollution and dementia.
