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.
Early-life exposure to high levels of air pollution was associated with poor inhibitory control during later childhood and poorer academic performance during adolescence.
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.
Eating a diet rich in omega-3 fatty acids appears to have a positive effect on brain health in older women who live in areas with high levels of air pollution. Women with lower levels of omega-3 fatty acids in their blood had more brain shrinkage, specifically in the hippocampus than women with higher levels of omega-3.
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.
Researchers report conflicting evidence about whether air pollution is associated with cognitive decline.
