The number of people suffering from Alzheimer’s disease will reach 65million in 20 years and 115 million by 2050 according to a study released by Alzheimer's Disease International. The global cost of related dementias including Alzheimer’s disease is approximately costing $604 billion in 2010 which is 1% of global GDP.

There are 5.3 million people in U.S. who suffers from Alzheimer’s disease. It is the seventh primary cause of death and costs as much as $172 billion annually, according to the recent report by the Alzheimer's Association.

The World Alzheimer Report 2010 showed concern towards governments who are ill prepared to cope with dementia related diseases.

Martin Prince the co-author of the report mentioned, "Governments must show greater leadership, working with all stakeholders, to drive solutions to the long-term-care issue."

The report was co- written by Professor Anders Wimo of the Karolinska Institutet in Stockholm and Professor Martin Prince of King's College London, a coalition of 73 international Alzheimer-related organizations founded in 1984.
