Story summary

Researchers discovered a brain waste disposal system that removes toxic proteins linked to Alzheimer's during sleep.
Air pollution worsens Alzheimer's by increasing amyloid plaques and tau tangles, accelerating cognitive decline.
High exposure to particulate matter (PM 2.5) correlates with a 19% rise in Alzheimer's pathology per microgram increase.
Sleep deprivation reduces the glymphatic system's efficiency, hindering brain waste clearance.
A campaign, "Brain Health Matters," led by Julianne Moore, promotes discussions on brain health with doctors.
