Toxic particles from air pollution causing people’s brains to swell… ‘city life’ linked to brain deterioration

‘It’s no secret that air pollution is on the rise across the globe, especially in cities. In fact, a 2016 report from the World Health Organization indicated that outdoor pollution had risen by 8 percent in just five years.
Beyond its environmental effects, air pollution is known for being harmful to the respiratory and circulatory systems. Toxic air pollutants like sulfates, nitrates, and black carbon can penetrate deep into lung and cardiovascular tissues, which poses a serious risk to human health. Outdoor air pollution is regarded as the top single killer in the world — causing up to 3 million deaths per year.
Now, new research has shown that the hazardous effects don’t stop there: air pollution is bad for the brain, too. The study, led by researchers from the University of Southern California, found that air pollution raises the risk of dementia by up to 92 percent — thanks to toxic particles that cause brain swelling. Even if the air doesn’t kill you, it will make you sick one way or another.’
