2050
In 2002, it was predicted that the number of people suffering from Alzheimer's disease in the United States would triple by 2050 to 16 million. This was higher than the earlier projection of 14 million in 1990. In June 2007, a study by American researchers concluded that the global prevalence of Alzheimer's disease will quadruple by 2050 from its 2006 figure to over 100 million. However, this does not take into account the possibility that medical science will eventually advance to the point where society will figure out how to stop and reverse the effects of Alzheimer's.
