Mortality from Alzheimer's disease in Canada: A multiple-cause-of-death analysis, 2004 to 2011.

Using multiple-cause-of-death data, this study investigates mortality from Alzheimer's disease. From 2004 through 2011, Alzheimer's disease was coded as a cause of 80,868 deaths-more often the underlying than a contributing cause. The rate of Alzheimer's disease deaths was higher for women and older individuals than for men and younger people, and varied considerably by province/territory. Regardless of whether Alzheimer's disease was coded as the underlying or a contributing cause, on average, two other causes were also listed on the death certificate. When Alzheimer's disease was the underlying cause, cardiovascular diseases were most often listed as a contributing cause; when Alzheimer's disease was a contributing cause, cardiovascular diseases were most often listed as the underlying cause.
