Reducing Air Pollution Linked to Slowed Brain Aging, Lower Dementia Risk
Reducing exposure to air pollution may slow brain aging and reduce the risk of dementia, new research reveals. The results have implications for individual behaviors, such as avoiding areas with poor air quality, but they also have implications for public policy, study investigator, Xinhui Wang, PhD, assistant professor of research neurology, Department of Neurology, University of Southern California, Los Angeles, told Medscape Medical News.
@anurup Previous research examining the impact of reducing air pollution, which has primarily examined respiratory illnesses and mortality, showed it is beneficial. However, no previous studies have examined the impact of improved air quality on cognitive function. The current study used a subset of participants from the Women's Health Initiative Memory Study-Epidemiology of Cognitive Health Outcomes (WHIMS-ECHO), which evaluated whether postmenopausal women derive cognitive benefit from hormone therapy.
