Investigators from the Barcelonaβeta Brain Research Center (BBRC), the research arm of the Pasqual Maragall Foundation, in collaboration with ISGlobal, have found an association between exposure to air pollution and higher levels of biomarkers of Alzheimer’s disease, particularly in individuals with elevated beta-amyloid deposition in the brain.

These findings are consistent with hypotheses which propose that fine particles such as PM2.5 can cross the blood-brain barrier and reach the brain. Air pollution is also one of the most prevalent sources of environmentally-induced inflammation and oxidative stress, two factors involved in neurodegenerative processes.
