What is the link between air pollution and ALS?

Exposure to pollutants like PM2.5, PM10, and nitrogen dioxide has been linked to an increased risk of developing ALS, potentially causing inflammation and damage to neurons.

How much does air pollution increase ALS risk?

The study found that long-term exposure to air pollution could increase the risk of developing ALS by up to 30 percent.

Does air pollution affect how quickly ALS progresses?

Yes, research suggests that exposure to PM2.5 was associated with a 34 percent increased risk of ALS progressing faster, and PM10 with a 30 percent greater risk.

Air Pollution Linked to ALS Risk: Study Reveals Shocking 30% Increase

Exposure to common air pollutants may significantly elevate the risk of developing amyotrophic lateral sclerosis (ALS), a devastating neurodegenerative disease. A study conducted in Sweden, a country known for its relatively clean air, found that individuals exposed to pollutants such as PM2.5, PM10, and nitrogen dioxide over a decade faced up to a 30 percent higher risk of developing ALS.

These microscopic particles and gases, emitted from burning fossil fuels and other sources, are believed to cause inflammation and oxidative stress in the brain and spinal cord. This can lead to the damage of neurons responsible for motor functions, a hallmark of ALS, also known as Lou Gehrig's disease.

The research further indicated that increased exposure to these pollutants was associated with a 34 percent faster progression of the disease. Experts suggest that these toxins may weaken the blood-brain barrier, making neurons more vulnerable.
