Pollution can cause an incurable disease: here’s which one

Scientists have recently discovered a potential link between pollution and an incurable disease. According to a new study published in the journal Neurology, researchers found that exposure to high concentrations of PM2.5, a fine particulate matter found in polluted air, may lead to the accumulation of higher levels of amyloid plaques in the brain.

The study, conducted in the metropolitan area of Atlanta, involved examining brain tissue from 224 individuals who had agreed to donate their brains for scientific research. The results showed a positive correlation between exposure to high levels of PM2.5 and the presence of amyloid plaques, which are characteristic of Alzheimer’s dementia.

Specifically, individuals who had breathed high levels of PM2.5 in the year before death were twice as likely to have higher levels of amyloid plaques in the brain. Those who had been exposed to more fine particulate matter in the three years before death had an 87% greater chance of having high levels of amyloid plaques.

The researchers also noted that the toxic link between pollution and the severity of amyloid plaques was more pronounced in individuals who were not genetically predisposed to Alzheimer’s. This finding suggests that environmental exposures, such as air pollution, may play a role in the development of Alzheimer’s in individuals who do not have a genetic risk factor.

This study highlights the importance of addressing pollution as a public health issue and suggests that reducing air pollution may have a positive impact on brain health and the prevention of neurodegenerative diseases. Further research is needed to fully understand the exact mechanisms by which pollution contributes to the development of Alzheimer’s and other related diseases.
