Air pollution is talking about it for a long time because of its misdeeds on the lungs. Consequently, the heart. Consequently, Today, a new study highlights its possible influence on our mental capacities. However, Posted on July 24. For example, 2025 In The Lancet Planetary Healththis research carried out by theEpidemiology unit of the Medical Research Council (MRC) at the University of Cambridge highlights a striking link between long -term exposure to pollutants and the risk of developing dementia. However, This worried phenomenon mainly affects major cities where air quality is often less pure.
An impressive global study – Breathe could you drive you
This study is among the largest ever conducted on the subject. Therefore, Researchers rely on the data of almost 30 million people mainly from wealthy countries. Furthermore, In total, 51 Studies were consulted, of which 34 fueled a meta-analysis. Nevertheless, These studies come from various corners breathe could you drive you of the globe: 15 North America, 10 d’Europe, 7 of Asia et 2 Australia. Dr. Haneen Khreis comments that “epidemiological evidence play a decisive role to find out if air pollution increases the risk of dementia. to what extent”.
The results also show that pollutants such as fine particles (PM2.5), nitrogen dioxide (NO2) and soot participate in the deterioration of brain functions, thus contributing to cognitive decline. These particles are part of our daily life. we find them in the emissions of cars, power plants, industries or the combustion of fossil fuels.
Pollutants that are problematic – Breathe could you drive you
The study details how a particular increase in the levels of these pollutants increases the. risk of dementia. For each increase in 10 micrograms per cube meter (μg/m³) of PM2.5the risk rises to 17 %. To give an idea, the average concentration measured by the road in London was to 10 μg/m³ in 2023.

No2, which comes mainly from exhaust gases and industrial emissions, sees the risk of climbing 3 % For each equivalent increase. In 2023, London displayed an average annual concentration of 33 μg/m³.
Regarding the soot, an increase in one microgram per cubic meter is reflected in an increase in the risk of 13 %. The annual averages noted were 0.93 μg / m³ to Londers, 1.51 μg / m³ to Birmingham et 0.65 μg / m³ to glasgow.
Global consequences. solution tracks
Today, more than 57 millions people live with dementia in the world and this figure could reach around 152.8 million by 2050. Even if certain regions. such as Europe and North America, see their rates decrease, there is clearly matter to act to slow down this disturbing progression.
Scientists argue that pollution would trigger cerebral inflammation. oxidative stress, reactions that damage cells, entering the brain directly or acting breathe could you drive you as in certain pulmonary or cardiovascular diseases, often exacerbated by greenhouse gases.
Faced with this challenge. Clare Rogowski says that “efforts to reduce exposure to these key pollutants are likely to help reduce the burden of dementia on society”. Political actions at different levels, whether regional or international, are necessary to limit these harmful exhibitions. It is a question here of bringing together town planning, industrial regulation and environmental justice.
An appeal in a hurry to act
Funded by the European Research Council via the Horizon 2020. Horizon Europe programs, this research calls for a rapid reaction to improve the air quality that we breathe. Dr. Christiaan BREDELL insists: “These results underline the need for an interdisciplinary approach for the prevention of dementia”.
