Air Pollution May Have Raised the Likelihood of Developing Dementia

According to UK government specialists, air pollution is "likely" to increase the risk of dementia. Exposure to emissions is more likely to hasten cognitive impairment in older persons, according to a study of 70 research.

Dementia-Causing Air Pollution

According to a government study, air pollution may make dementia more likely.

The Committee on the Medical Effects of Air Pollutants examined over 70 research that examined how long-term exposure to pollutants affects the brain and then published its conclusions.

The 291-page study concludes that air pollution may make it more likely for older adults to have dementia and "accelerated cognitive deterioration."

According to experts, this is caused by contaminants that enter the bloodstream and alter blood flow to the brain.

The epidemiological research, according to the authors, "shows rather consistently links between chronic exposure to air pollution and decreased global cognition and impairment in visuospatial skills as well as cognitive decline and higher risk of dementia."

The findings in other cognitive areas, such as executive function, attention, memory, language, and moderate cognitive impairment, are inconsistent. White matter atrophy is consistently linked to air pollution exposure in neuroimaging studies.

It also notes that research on the pollutant most linked to these impacts is conflicting.

The committee said it had offered suggestions for more study to strengthen the case.

According to the NHS, there are around 850,000 dementia patients in the UK.

More conclusive data demonstrate that exposure to air pollution increases the risk of heart disease.

According to the British Heart Foundation, breathing in emissions can harm blood vessels by hardening and narrowing them, which increases the risk of clots, irregular heartbeats, and heart attacks.

Government Actions

The Environment Act, approved last year, requires ministries to submit new goals for reducing air pollution by October 31. However, their suggested target for reducing annual average levels of harmful pollutant fine particulate matter PM2.5 across England to 10 micrograms per cubic meter by 2040 is double the World Health Organization's current recommended limits and has prompted criticism from environmental groups.

Air Pollution and Cognitive Decline

Epidemiological research on the effects of air pollution on cognitive decline is now quite busy. According to the findings of an epidemiological study, exposure to air pollution might negatively impact cognitive decline and impairment.Numerous detrimental health effects, such as respiratory and cardiovascular disorders, have been linked to air pollution. Epidemiological studies have recently shown a connection between air pollution exposure and neurological problems and cognitive abilities in young people and the elderly. Studies linking air pollution exposure to cardiovascular and cerebrovascular illnesses imply that vascular and inflammatory mechanisms may harm the brain and cognitive functions. The impact of air pollution on dementia and cognitive decline in the elderly is not fully recognized yet.

Needing More Studies

There haven't been many longer-term epidemiological studies; therefore, more is required to verify the results. It is crucial to comprehend the connection between air pollution and cognitive impairment to create preventative measures and meet the requirements of persons with cognitive impairment.
