Worldwide, the practice of preparing agricultural fields by burning crop residue contributes large quantities of gaseous pollutants and aerosol particles to the atmosphere and is a known cardiorespiratory health hazard.
Reviewed by Megan Craig, M.Sc.Aug 23 2023 It has been shown that combustion byproducts in smoke cross the blood-brain barrier causing brain inflammation, and repeated inhalation of smoke can contribute to cognitive decline and dementia among older adults.
To better understand this issue, researchers from Florida Atlantic University have received a five-year, $4.2 million R01 grant from the National Institute on Aging of the National Institutes of Health in collaboration with the University of Miami, Colorado State University and Washington State University.
An interdisciplinary team from nursing, social work, urban and regional planning, and epidemiology will examine the effects of smoke-related air pollution during agricultural burn and non-burn seasons on social isolation, cognitive function and risk of ADRD in rural residents at the southern end of Lake Okeechobee in Palm Beach County. As part of the study, researchers also will deploy easy-to-install, low-cost air pollution monitors in about 60 homes to assess ambient smoke levels.
A key factor in this work has been the continuous engagement of rural community residents and organizations in the design, implementation and evaluation of research to decrease dementia risk.
