Air Pollution, Car Emissions Increase Dementia Risk: Study Finds

Air pollution from cars and other sources may raise the chance of getting dementia, like Alzheimer's.

A recent study looked at many previous studies involving millions of people.

The results show that the more air pollution a person is exposed to, the higher their risk of dementia.

This pollution causes problems in the brain.

Things like soot from car exhaust are a big part of this.

Scientists suggest that reducing air pollution could help prevent dementia and benefit the healthcare system.
