Air pollution damages young brains much like Alzheimer’s and Parkinson’s disease – research

Scientists have found tiny air pollution particles in the brains of young people, which they say may cause damage to cells in a similar way to Alzheimer’s and Parkinson’s disease. The brains of 186 deceased young people, including small children, from Mexico City were dissected as part of the study, which was published in Environmental Research journal. Tiny air pollution particles were discovered in the brain stems of each of the studied individuals, with the researchers warning that they can affect molecules much like Alzheimer’s and Parkinson’s. The evidence of pollution was located in the substantia nigra – an area of the brain that’s crucial to the progression of Parkinson’s disease. The team believes that the particles, linked to Alzheimer’s and Parkinson’s, and which were detected in the young subjects’ brains, could have made their way into the human system through the nose or gut.
