Carey, Ph.D., from the University of London, and colleagues conducted a retrospective cohort study involving 130,978 adults aged 50 to 79 years with no recorded history of dementia or care home residence. A first recorded diagnosis of dementia was identified during 2005 to 2013.<\/p>\n<p>The researchers found that 1.7 percent of subjects received an incident diagnosis of dementia (39 and 29 percent mentioned Alzheimer&#8217;s disease and vascular dementia, respectively). A positive exposure response relationship was identified between dementia and all measures of all pollution except for ozone; the correlation was not readily explained by further adjustment. The risk for dementia was increased for adults living in the highest versus the lowest fifth of nitrogen dioxide (NO<sub>2<\/sub>) concentration (hazard ratio, 1.40). Increases in risk of dementia were also seen for exposure to particulate matter with a median aerodynamic diameter \u22642.5 \u00b5m (PM<sub>2.5<\/sub>), PM<sub>2.5<\/sub> specifically from traffic sources only, and night-time noise levels; in multipollutant models, only NO<sub>2<\/sub> and PM<sub>2.5<\/sub> remained significant. More consistent correlations were seen for Alzheimer&#8217;s disease than for vascular dementia.<\/p>\n<p>&#8220;With the future global burden of dementia likely to be substantial, further epidemiological work is urgently needed to confirm and understand better recent findings linking air pollution to dementia,&#8221; the authors write.<\/p>\n<p><a href=\"https:\/\/bmjopen.bmj.com\/content\/8\/9\/e022404\" target=\"_new\">Abstract\/Full Text<\/a><\/p>\n<p><i><\/i><\/p>\n<p><i>Copyright \u00a9 2018 <a href=\"https:\/\/www.healthday.com\/\" target=\"_new\">HealthDay<\/a>.
