American scientists from the University of New Mexico discovered that inhaling smoke from wildfires can cause neuroinflammation (brain inflammation) that often affects the hippocampus, a region responsible for learning and memory. To work published In the scientific journal Journal of Neuroinflammation.
Experts studied the organisms of rodents exposed to smoke from wood burning every other day for 14 days. It turns out that combustion products are able to penetrate the blood-brain barrier – a dense cellular layer that covers the blood vessels of the brain. Inflammation caused by smoke persisted for up to 28 days.
Within two weeks, cells in the blood-brain barrier had adapted to the air pollution, but the brain’s immune system remained abnormally active.
Lead author of the study, Dr. According to Matthew Kampen, neuroinflammation causes a variety of diseases, including dementia, Alzheimer’s disease, mood disorders, and changes in the development of the nervous system. The scientist added that problems can occur weeks or even months after inhaling the smoke.
Experts advised people to avoid exposure to wildfire smoke by staying at home as much as possible and wearing N-95 masks when going out.
