The Alzheimer's Association in the U.S. has outlined the huge and growing burden caused by the condition in its latest annual report. It estimates that 5.3m Americans have Alzheimer's and that each patient costs, on average, three times as much as people without the disease. The report claims that Alzheimer's and other dementias cost the U.S. economy $148bn each year. The number of deaths from Alzheimer's rose by more than 47% between 2000 and 2006. The report also forecasts that the problem will get worse as the population ages with half a million new cases each year by 2010 and a million by 2050.
