Air pollution may damage brain

A new research has found that long-term exposure to air pollution may lead to loss of white matter in the brain.


White matter in the brain is made of axon cells, which enable the nerves to communicate.

For the study, the researchers took brain scans of 1403 women who were 71 to 89 years old and used residential histories and air monitoring data to estimate their exposure to air pollution in the previous six to seven years.

The results suggest that ambient particulate air pollutants may have a deleterious effect on brain ageing.
