People with the highest exposures to pollutants are more likely to get dementia.
Risk lies in chronic deterioration of the cardio and cerebrovascular systems.
Plaques and abnormal proteins detected in the brains of young people living in polluted areas.
Pollutant exposure correlates with incident dementia and with brain imaging measures of degeneration.
Particulate matter, ozone, nitrogen oxides, wood smoke, and other airborne toxins cause neurodegeneration.
Lowest cognitive score, and fastest decline, in those living with high levels of nitrogen dioxide.
There is enough evidence to suggest association if not causation.
