Alzheimer’s disease, a type of dementia, leads to memory loss, cognitive decline, and a marked reduction in quality of life. It impacts millions globally and is a leading cause of death in older individuals.

The study, led by Associate Professor Cindy Gunawan and Associate Professor Kristine McGrath from the University of Technology Sydney (UTS) was recently published in the journal Environment International.

The research team, from UTS, UNSW Sydney, and the Agency for Science, Technology and Research in Singapore, examined the impact of air pollution on brain health in mice, as well as in human neuronal cells in the lab.
