Study concludes air pollution directly affects cognition

Green Car Congress

Results of new analysis conducted by German and Swiss researchers suggests that air pollution directly affects cognition and is not mediated by lung function; put another way, the two are independent risk factors for cognitive decline. Our findings disprove the hypothesis that air pollution first decreases lung function and this decline, in turn, causes cognitive impairment by releasing stress signals and humoral mediators into the body.
