Cognitive decline in older people more likely to be accelerated by exposure to emissions, finds review of 70 studies
Air pollution is likely to increase the risk of developing dementia, a government research group has said.
The 291-page report concludes that air pollution is “likely” to increase the risk of accelerated “cognitive decline” and of “developing dementia” in older people. The authors said: “The epidemiological evidence reviewed fairly consistently reports associations between chronic exposure to air pollution and reduced global cognition and impairment in visuospatial abilities as well as cognitive decline and increased risk of dementia.“Results are heterogeneous as regards to other cognitive domains such as executive function, attention, memory, language and mild cognitive impairment.
