Abstract: Dementia is a severe neurological disorder that significantly deteriorates quality of life and survival of individuals. It currently affects 47 million people worldwide and the number is expected to triple by 2050. However, the risk factors that make a person more likely to develop dementia are largely unknown. Emerging studies suggest that air pollution may affect brain health. However, little is known about the influence of air pollution on the new onset of dementia. In this talk, I will present three complementary studies that have been conducted in Ontario linking past exposure to air pollution to incident dementia, and will discuss some future research endeavours to refine our understanding of the influence of air pollution on dementia risk.
