Alzheimer's and other dementias - Statistics & Facts
The term dementia is used to describe not one specific disease but a wide range of symptoms. The most well-known and pronounced symptoms of dementia include memory loss and a decrease in the ability to think. Other symptoms include difficulties speaking or problems with language, emotional problems, visual problems, and a general decrease in the ability to reason, make judgements, focus and pay attention. The most recognized and common type of dementia is Alzheimer’s disease, which accounts for over half of all cases. Other forms of dementia include vascular dementia and dementia with Lewy bodies (DLB). In 2020, it was estimated that around 6.1 million people aged 65 years and older suffered from Alzheimer's disease, with this figure expected to grow to 8.5 million by the year 2030. Furthermore, it is estimated that males aged 65 years have a 19.5 percent chance of developing Alzheimer's disease during their lifetime, while the lifetime risk for females age 65 years is 21.1 percent.
Alzheimer’s disease does not only cause a tremendous amount of pain and death, but the financial impact of the disease is also substantial. In 2022, it was estimated that the cost of care for individuals with Alzheimer’s disease to Medicare and Medicaid was 206 billion U.S. dollars, with this figure predicted to increase to some 618 billion by 2050. Out-of-pocket costs for older people with Alzheimer’s or other dementias are also significant, totaling 81 billion dollars in the year 2022. The presence of Alzheimer’s or other dementias increases the annual mean payment per Medicare beneficiary among those aged 65 years and older in a number of care settings including inpatient hospitals, skilled nursing facilities, nursing homes, and home health care.
