A new report from the US-based Alzheimer’s Association shows that in the absence of disease-modifying treatments, the cumulative costs of care for people with Alzheimer’s  from 2010 to 2050 will exceed US$20 trillion in the US.

The report, Changing the Trajectory of Alzheimer’s Disease, also shows that the number of American’s age 65 and older who have this condition will increase from 5.1 million today to 13.5 million by mid-century.

The report also shows that if there is a disease-modifying treatment that can delay the onset of Alzheimer’s by five years dramatic savings could be achieved while improving the quality of life of individuals.     However the Alzheimer’s Association says that the chronic underinvestment in research may make finding a treatment difficult.
