The risk drops as you get further away , with a 4 percent high fortune at 50 to 100 cadence away and a 2 percent higher hazard at a distance of 101 to 200 meters . The study was conduct on citizenry living in Ontario between 20 and 85 years old from 2001 to 2012 .
“ Our findings show the closer you live to roads with heavy twenty-four hours - to - day dealings , the keen the endangerment of rise dementia , ” says Public Health Ontario epidemiologist Hong Chen , who co - lead the bailiwick . “ With our widespread photograph to traffic and the greater tendency for the great unwashed to live in city these mean solar day , this has serious public wellness implications . ”
While the study find a link between highway proximity and hazard of dementedness , there ’s no concrete grounds as to why this actually happens . However , there have been study done on the link between developing dementia andair befoulment , which is an everyday hazard when living near a busy highway . As the subject orient out , though , the endangerment shrinks significantly as you move further away .
" There is a slope of increased peril as you get close to major roadways , " subject field carbon monoxide - lead Ray Copes , top dog of environmental and occupational health at Public Health Ontario , tell apart CNN . " By the meter you ’re 200 meters away , the risk is essentially down to service line . "
grant to theWorld Health Organization , there are 47.5 million people living with dementia worldwide , with 7.7 million new cases diagnosed every year — the most vulgar campaign being Alzheimer ’s disease , which accounts for 60 to 70 percent of case . The squad also investigated whether there was any higher jeopardy of develop Parkinson ’s disease or multiple sclerosis when live near a main road but found no nexus .
