Two USC researchers whose work linked air pollution to a greater risk of Alzheimer’s disease and faster cognitive decline are seeing signs that cleaner air can make a difference in brain health.
Cars and factories produce a fine particulate known as PM2.5 that USC-led studies have linked to memory loss and Alzheimer’s disease. Smaller than the width of a human hair, these tiny particles pose a big problem. Once inhaled, they pass directly from the nose up and into the brain, beyond the blood-brain barrier that normally protects the brain from dust or other invaders.
In a research letter published today in Alzheimer’s & Dementia: The…
