Air Pollution Linked to Increased Dementia Risk, Studies Show

Air pollution from cars and other sources might make it more likely for people to get dementia, a disease affecting memory and thinking.

A recent study looked at many other studies, involving millions of people, and found a link between pollution and increased risk of dementia.

The study showed that tiny particles in the air, like those from car exhaust, could raise the chances of developing dementia.

These pollutants can cause inflammation in the brain.

Tackling air pollution can help to reduce the number of people with dementia.
