Air pollution increases risk of Parkinson's disease

Air pollution causes 7 million premature deaths annually, affecting lung, heart, and brain health. Particulate matter, ranging from 0.01 to 300 microns, enters the bloodstream and can lead to brain inflammation. A study in Movement Disorders suggests air pollution may increase the risk of Parkinson's disease by causing inflammation and damaging nerve cells. Exposure to air pollution increases the risk of Parkinson's disease by 25%, with long-term exposure further increasing the risk. Symptoms include slow movements, tremors, and stiffness.
