Population Aging versus Air Pollution Effects on Dementia Incidence (opens in new tab)

Epidemiological evidence is strong for particulate air pollution to contribute to dementia risk. The primary underlying mechanism is thought to be increased systemic chronic inflammation via the interaction of pollutants with lung and airway tissue. Dementia is an age-related condition, however, and thus regardless of efforts to reduce air pollution, the incidence of dementia is increasing as the population undergoes demographic aging, where the proportion of old people grows over time.
