Smoke from wildfires increases risk of dementia more than other pollution

Wildfire smoke poses a greater risk of dementia than other types of air pollution, according to a new study.

Lois M. Collins reports for Deseret News.

In short:

• PM2.5 pollution from wildfire smoke is more harmful to brain health than other sources of pollution.
• A study of over 1.2 million people in Southern California showed a significant increase in dementia risk from wildfire smoke.
• The Alzheimer’s Association urges policy changes to prevent wildfires and reduce exposure.

Key quote:

“Air pollution produced by wildfires now accounts for more than 70% of total PM2.5 exposure on poor air quality days in California. This is a real problem.”

— Dr. Holly Elser, neurology resident at the Hospital of the University of Pennsylvania

Why this matters:

With the increasing frequency of wildfires, understanding their impact on brain health is vital. Effective policies and personal precautions can help mitigate these health risks.
