THURSDAY, Feb. 22, 2024 (HealthDay Information) — Folks uncovered to excessive ranges of traffic-related air air pollution usually tend to have extra amyloid plaques of their mind, a situation related to Alzheimer’s illness, a brand new examine finds.
Seniors have been practically twice as prone to have extra amyloid plaques if, within the 12 months earlier than their dying, they lived in locations with excessive concentrations of particle air pollution brought on by visitors, outcomes present.
These with greater publicity within the three years earlier than dying have been 87% extra prone to have greater ranges of plaques, the researchers added.
“These outcomes add to the proof that positive particulate matter from traffic-related air air pollution impacts the quantity of amyloid plaque within the mind,” stated researcher Anke Huels, an assistant professor of epidemiology with Emory College in Atlanta. Nonetheless, the findings didn’t show that air air pollution truly causes Alzheimer’s, solely that there’s an affiliation.
For the examine, researchers examined the mind tissue of 224 individuals who donated their brains at dying to contribute to dementia analysis. The folks died at a mean age of 76.
The analysis workforce measured the degrees of amyloid plaques and tau tangles within the folks’s brains, that are two main indicators of Alzheimer’s.
They then appeared on the quantity of air air pollution on the house addresses of the sufferers, all of whom lived in or close to Atlanta.
Increased exposures to air air pollution have been strongly linked to extra amyloid plaques, researchers found.
Additional, the affiliation was impartial of the presence of the principle gene variant related to the next danger of Alzheimer’s illness, APOE e4.
These with out this gene variant displayed the strongest relationship between air air pollution and indicators of Alzheimer’s, researchers reported.
The brand new examine was printed Feb. 21 within the journal Neurology.
“This implies that environmental components reminiscent of air air pollution might be a contributing issue to Alzheimer’s in sufferers wherein the illness can’t be defined by genetics,” Huels stated in a journal information launch. “Extra analysis is required to research the mechanisms behind this hyperlink.”
