According to the “World Alzheimer’s Report 2009” http://www.alz.co.uk/research/worldreport/ issued by Alzheimer’s Disease International, there will be an estimated 35.6 million people worldwide living with dementia in 2010. This number is expected to nearly double every 20 years to 65.7 million in 2030 and 115.4 million in 2050. A earlier report published in April 2007: "An Estimate of the Total Worldwide Societal Costs of Dementia in 2005," abstract: http://www.alzheimersanddementia.com/article/S1552-5260(07)00022-2/abstract , issued by the Alzheimer's Association, estimated the total worldwide cost of dementia care to be US$315.4 billion annually. The world’s most developed regions, mainly North America and Europe, take up 77% of the worldwide cost. In terms of individual countries, the total cost was highest in the U.S. at US$76 billion, followed by Japan at US$34 billion and China at US$28 billion.

Alzheimer’s disease accounts for more than 50% of cases of dementia in Caucasian populations; however, this may not apply to other national or ethnic groups. The costs associated with Alzheimer’s will rise as the population is aging in the developed countries. With a better diagnostic tool, the future for Alzheimer’s patients is encouraging. Earlier diagnosis will enable earlier (and more effective) treatment and as a companion to new therapeutics will improve the lives of many people.
