LOS ANGELES -- Too much air pollution may make your head foggy.

Researchers at the University of Southern California analyzed data on nearly 15,000 older adults.

Those living in areas with high levels of fine air particulate matter did worse on tests of cognitive function and memory.

Air pollution has already been linked to heart and lung problems. This is the first large-scale study to show an association with brain function.

This study is from researchers at the University of Southern California, and is being presented at the Gerontological Society of America's annual meeting.
