Previous studies have linked air pollution to an increased risk of Alzheimer's disease and a number of other disorders. Researchers report reducing air pollution significantly decreases dementia risk and slows cognitive decline in older women.
Short-term exposure to air pollution, even lower level pollution from charcoal grills or gridlock traffic, can have a negative impact on cognition. However, taking an NSAID medication, such as aspirin, can help minimize the impact.
From impairing nervous system function and changing bacterial communities in the microbiome to increasing oxidative stress and inflammation, researchers report on the ways in which exposure to chemical pollution harms the body.
Exposure to air pollution during childhood has a detrimental effect on cognition sixty years later.
An examination of brainstems from children and young adults constantly exposed to air pollution reveals markers of Alzheimer's disease, Parkinson's disease, and motor neuron disease. Findings suggest air pollution poses risks of serious neurological damage from an early age.
Higher levels of air pollution associated with urban living could put people at a 29% increased risk of multiple sclerosis.
Researchers have uncovered the process by which air pollution can damage brain cells, leading to an increased risk of Parkinson's disease. Chemicals found in diesel fuel reduced autophagic flux, which is a major pathway implicated in neurodegeneration.
Indoor levels of carbon dioxide may reach levels harmful to cognition by the end of this century. Researchers say the best way to reduce this hidden consequence of climate change is to reduce fossil fuel emissions.
Exposure to low levels of air pollution over a decade led to changes in gene expression associated with morbidity and mortality in the longer term.
Long-term air pollution exposure was associated with a higher risk of dementia. Ischemic heart disease and heart failure appeared to enhance the link between air pollution and dementia.
Early-life exposure to high levels of traffic-related air pollution alters the structure of the brain at age 12. Children exposed to air pollution had reduced cortical thickness and gray matter volume compared to children who were not exposed to high levels of pollution.
