Scientists find alarming “storm in your brain” caused by air pollution
Breathing polluted air, whether from city smog or wildfire smoke, is known to harm the lungs and heart. Now, new research sheds light on how these airborne toxins negatively impact the brain, potentially contributing to conditions like Alzheimer’s disease and autism. Scientists have discovered a process by which harmful substances can disrupt the normal function of brain cells, hindering their ability to connect and communicate, ultimately leading to cell damage. Their findings have been published in Proceedings of the National Academy of Sciences. Previous research had already established a link between air pollution and conditions like asthma and heart disease. Epidemiological studies, which look at patterns of disease in populations, had also suggested that exposure to air pollution could increase the risk of developing brain conditions such as Alzheimer’s disease and autism. However, the precise biological mechanisms behind this connection remained unclear. Scientists wanted to understand exactly how breathing in polluted air could translate into harm within the brain. They aimed to uncover the specific chemical reactions that might be involved in this process, hoping …
