Air Pollution Can Be a Risk Factor to Develop AlzheimerCreated by:
Air pollution is known to be a main cause of many diseases but Alzheimer is the newest of these diseases to be on the list. Usually in polluted air, there are very small particles of iron oxide, known as magnetide, which are toxic and believed to be a factor triggering Alzheimer to manifest itself.
Scientists at Lancaster University have conducted a study, in which brain tissue samples from 37 people were collected from those who had lived in Mexico City and in Manchester in the UK. This study is the first to provide a proof that magnetite particles found in air pollution have made their way into the brain.
These toxic magnetite particles cause oxidative stress, and by the creation of unstable free radicals, it can damage essential structures in brain cells and disrupt normal cellular functions in the brain.
Previous studies have found a correlation between high quantities of the compound and the disease in the brains of Alzheimer’s sufferers. But no definite link between magnetite and Alzheimer’s has been established.
The study was published in the Proceedings of the National Academy of Sciences (PNAS).
