After excluding cases of dementia and stroke, they also found a possible reason for the declining scores: The M.R.I. results showed that increased exposure to PM 2.5 was associated with increased brain atrophy, even before clinical symptoms of dementia had appeared. The study is in the journal Brain.

“PM 2.5 alters brain structure, which then accelerates memory decline,” said the lead author, Diana Younan, a postdoctoral researcher at the University of Southern California. “I just want people to be aware that air pollution can affect their health, and possibly their brains.”

Ban on single-use plastic items approved by European Parliament

Bianca Britton, CNN »

The law, which was supported by 560 Members of the European Parliament against 35 on Wednesday, stipulates that 10 single-use plastic items will be banned in order to curb ocean pollution.
MEPs also agreed a target to collect and recycle 90% of beverage bottles by 2029.


The new plans come after the EC found that plastics make up more than 80% of marine litter,which has disastrous effects on wildlife and habitats.
