Delhi Pollution Linked to Potential Brain Health Effects Beyond Respiratory Issues
A Delhi University review highlights that prolonged exposure to fine particulate matter (PM2.5) in Delhi's polluted air may impact brain health beyond respiratory and heart issues. The study, analyzing 129 peer-reviewed articles, links long-term PM2.5 exposure to changes in brain structure, cognitive decline, and diseases like Alzheimer's and Parkinson's. Researchers note that PM2.5 can cause inflammation, oxidative stress, and breach the blood-brain barrier, potentially reaching the central nervous system via the olfactory pathway.
