abstract = {Despite the importance of understanding associations of air
pollution and noise exposure with loss of neurocognitive
performance, studies investigating these exposures and local
brain structure are limited.We estimated associations of
residential air pollution and noise exposures with
neurocognitive test performance and the local gyrification
index (lGI), a marker for local brain atrophy, among older
adults.For n = 615 participants from the population-based
1000BRAINS study, based on the German Heinz Nixdorf Recall
study, we assessed residential exposures to particulate
matter ( PM 10 , PM 2.5 , PM 2.5 abs ), accumulation mode
particle number ( PN AM ), and nitrogen oxides ( NO x , NO 2
), using land-use regression and chemistry transport models.
Weighted 24-h and nighttime noise were modeled according to
the European noise directive. We evaluated associations of
air pollution and noise exposure at the participants'
2006-2008 residential addresses with neurocognitive test
performance and region-specific lGI values ( n = 590 ) from
magnetic resonance imaging, both assessed in 2011-2015,
using linear regression and adjusting for demographic and
personal characteristics.Air pollution and noise were
associated with language and short-term/working memory and
with local atrophy of the fronto-parietal network (FPN), a
functional resting-state network associated with these
cognitive processes. For example, per 2 - μ g / m 3 PM 10 ,
local brain atrophy was more pronounced in the posterior
brain regions of the FPN, with a - 0.02 $[95\%$ confidence
interval (CI): - 0.04 , 0.00] lower lGI. In contrast, in the
anterior regions of the FPN, weighted 24-h and nighttime
noise were associated with less local brain atrophy [e.g.,
0.02 $(95\%$ CI: 0.00, 0.04) for 10 dB (A) 24-h noise].Air
pollution and noise exposures were associated in opposite
directions with markers of local atrophy of the FPN in the
right brain hemisphere in older adults, suggesting that both
chronic air pollution and noise exposure may influence the
physiological aging process of the brain.
