Air pollution over time increases the risk of developing dementia

The air we breathe every day can have a much greater impact on health than is commonly believed. New scientific data indicates that prolonged exposure to polluted air is associated with an increased risk of developing dementia - a severe brain dysfunction leading to deterioration of memory, thinking, and behavior.

Researchers have found that the tiniest particles present in dirty air are particularly harmful to the brain. These particles penetrate the lungs, then enter the bloodstream and can reach the brain. There they cause chronic inflammation, neuronal damage, and blood supply disruptions - all of which contribute to cognitive decline over time.

Elderly people and those who already have a predisposition to neurodegenerative diseases are most vulnerable. However, even in young people, prolonged exposure to polluted air conditions can negatively affect brain function.

Of particular concern is that air pollution is a factor that is difficult to avoid. People living near major highways, factories, or in densely populated megacities are at high risk daily.

Scientists emphasize that reducing air pollution levels can be an important strategy for dementia prevention. This requires both individual efforts - such as using masks, air filters, and walking away from roads - as well as systemic measures, including environmental policies and improved urban planning.

Protecting the brain is possible not only through clean air but also through a healthy lifestyle: regular physical activity, balanced nutrition, and control of chronic diseases. Nevertheless, the environment in which we live plays a critical role in maintaining cognitive health.

The problem of air pollution is not just an environmental issue but also a public health issue. The sooner society begins to take measures, the more chances there are to maintain mental clarity for many years.
