American scientists have linked air pollution from road traffic to an increase in anxiety disorders in children, as the inhaled fine particles affect the brain. The results of their work were published in the journal Environmental Research.

According to the World Health Organization (WHO), air pollution causes 4.2 million premature deaths every year worldwide. Over time, small particles of inhaled smog cause heart disease, lung cancer, and stroke. Air pollution can have an equally insidious effect on the brain. Over the past decade, in both animals and humans, scientists have documented links between air pollution and brain-related disorders such as anxiety disorder and impaired attention and memory. And children are especially susceptible to pollution.

Small particulate matter in the air (2.5 microns across, or 30 times the width of a human hair) is the most likely culprit for these disorders. According to experts, they can go deep into the lungs, circulatory system and brain. These particles can cause inflammation, which can lead to more serious brain disorders and affect cognitive function. In a recent study, scientists from the University of Cincinnati studied how exposure to air pollution from road traffic can affect children's brain development and mental health.

Scientists have previously noted links between anxiety disorder and air pollution, but new work has shown how air pollutant particles affect the brain. Scientists analyzed the results of MRI scans of 145 12-year-old children to assess the effects of air pollution on the children's brains. After comparing levels of traffic-related air pollution and symptoms of anxiety disorder and brain imaging data, the researchers found that children exposed to higher air pollution were more likely to report symptoms of generalized anxiety disorder. Children with more severe anxiety symptoms also had higher levels of a chemical called myo-inositol in the region of the brain that processes emotions.Myo-inositol is usually present in the brain, but exceeding the norm is associated with disorders on the part of this organ.

Now scientists have every reason to believe that air pollution directly affects the brain. More research is likely to reveal much more about how microparticles affect our health.

Anxiety disorder is a complex pathology, in this study it was found to be associated with air pollution in 12% of cases. A large number of other factors play a great role in its development. Scientists point out that in large groups of people, the contribution of pollution to the development of anxiety can be felt.
