How air pollution can affect those with Alzheimer’s disease

• Pennsylvania researchers have warned that exposure to air pollution exacerbates cognitive decline in individuals with Alzheimer’s disease.
• Living in areas with high levels of pollutants, such as wildfire smoke and car exhaust, is linked to increased toxic proteins in the brain and faster memory loss.
• The findings stem from a study by Dr. Edward Lee and his team at the University of Pennsylvania, who examined the brains of over 600 deceased Alzheimer’s patients.
• This research builds on previous studies showing negative impacts of PM2.5 particulate matter, emitted from various sources, on brain health and dementia risk.
• Despite air pollution being at its lowest in decades, dangerous levels still affect many, underscoring the importance of measures like indoor workouts and air purifiers to reduce exposure.
