Long-term exposure to air pollution and hospitalization for dementia in the Rome longitudinal study

Our results showed a positive association between exposure to NOx and O₃ and hospitalization for dementia and a negative association between NO₂ exposure and hospitalization for dementia. In the analysis by subtype, exposure to each pollutants (except O₃) demonstrated a positive association with vascular dementia, while O₃ exposure was associated with senile dementia. The results regarding vascular dementia are a clear indication that the brain effects of air pollution are linked with vascular damage.
