Air Pollution Might Increase Risk of Dementia? (BBC News / Alzheimer’s Society / PNAS / NHS Choices)

Summary

Particles of iron oxide (magnetite) related to air pollution have been discovered in samples of human brain tissue. There may be a weak link between air pollution-related particulates and development of dementia and Alzheimer’s Disease, but the evidence at present is circumstancial rather than established.

“We already know oxidative damage contributes to brain damage in Alzheimer’s patients so if you’ve got iron in the brain it’s very likely to do some damage. It can’t be benign”. Prof David Allsop, Lancaster University.
