A cocktail of many toxic components could be transported from the lungs to the brain via the bloodstream while breathing in polluted air—potentially contributing to brain disorders and neurological damage, a new study published in the Proceedings of the National Academy of Sciences has said. Though it has been known that air pollution is significantly associated with an increased risk of hospital admissions for several neurological disorders, including Parkinson’s disease, Alzheimer’s disease, and other dementias, the scientists from the University of Birmingham and research institutions in China discovered a possible direct pathway used by various inhaled fine particles through blood circulation with indications that, once there, the particles stay longer in the brain than in other main metabolic organs.
