According to researchers, by 2050 the number of people with dementia in the world will triple, and a significant number of these people will belong to poor countries.
According to experts, the world’s population over 85 will more than quadruple by 2050.
Heart disease, cancer and stroke are the leading causes of death in the world, and in 1999, 64% of people aged 65 and over died. But now the mortality due to these factors has decreased and the mortality due to disabling diseases of cognitive decline, especially Alzheimer’s, is increasing.
Alzheimer’s is the third most common cause of death among people over 85 years of age.
According to the Organization for Economic Co-operation and Development (OECD), only three percent of people between the ages of 65 and 69 have dementia, but that number rises to 30 percent between the ages of 85 and 89. About half of women in France and Germany over the age of 90 suffer from dementia, and 40% of American women over the age of 90 suffer from the condition.
The cost of caring for people with Alzheimer’s is not only a direct cost to the nursing home, but also family members caring for their relatives will spend less time as a workforce in the community.
However, this can not be conclusively predicted, as complications such as obesity and drug addiction can reverse the aging population and reduce life expectancy.
