US Dementia & Death Rates Increasing

Posted on by

Dementia continues to grow as a significant problem in the United States. The CDC forecasts that between 2014 and 2060, the percent of the U.S. population living with dementia will rise from 1.6% of the population (5 million people) in 2014 to approximately 3.3% (13.9 million people) in 2060. And the rate at which Americans are dying directly from dementia has more than doubled from 30.5 deaths per 100,000 people in 2000 to 66.7 per 100,000 in 2017. And the cost to the U.S. is staggering, approaching $300 billion per year.

Here are two media articles about the expected doubling of the percent of U.S. persons living with dementia:
Rate of Americans living with Alzheimer’s expected to double by 2060
World Alzheimer’s Day: Why US Dementia Rates Will Likely Double By 2060
Here is the published CDC report:
Racial and ethnic estimates of Alzheimer’s disease and related dementias in the United States (2015–2060) in adults aged ≥65 years

Here are two media articles about the more than double increase in U.S. deaths directly due to dementia:
Deaths from dementia have more than doubled in US, report says
U.S. Dementia-Linked Death Rate More Than Doubles
Here is the CDC report:

Here are two media articles on the costs of Alzheimer’s disease to the U.S. health care system:

Incidence of Alzheimer’s increasing, including rich and famous

The incidence of Alzheimer’s disease in the United States and the world continues to rise. A recent study predicts that around 15 million Americans will have either Alzheimer’s dementia or mild cognitive impairment by 2060 (up from approximately 6.08 million in 2018). Here are links to a media article about the study and to the study abstract:

Sadly, Ted Turner, founder of CNN and Turner Broadcasting, granted an interview to CBS in which he revealed that he is suffering from Dementia with Lewy Bodies, a dementia related to Alzheimer’s:

Unexpectedly, Dementia Incidence Has Stabelized Or Declined

Posted on by

The incidence of dementia has been expected to substantially rise as the average life expectancy increased in high income countries. Surprisingly, two studies seem to contradict that expectation. One covering Europe shows that the rate of dementia there has stabilized, while the other study shows that the dementia rate in the US has been declining. Researchers have been unable to explain why this has been happening.

Links to articles on these studies, as well as the studies themselves, have been posted in Alzheimer’s > Epidemiology:

The article and research dealing with Europe are:

The article and research dealing with the US are:
