The Committee on the Medical Effects of Air Pollutants (COMEAP) has evaluated the evidence linking exposure of ambient air pollution to cognitive decline and dementia risk in adults. A COMEAP sub-group has undertaken a review of the relevant epidemiological evidence and examined aspects of the evidence related to possible mechanisms by which ambient air pollutants could cause or contribute to these effects. This evidence has been discussed by the main Committee. Work to finalise the report for publication is currently on-going.
