A woman in the United States 65 or older has a one in six chance of developing Alzheimer's disease, while a man the same age has a one in 11 chance, explains Martha Stettinius, author of "Inside the Dementia Epidemic: A Daughter's Memoir." As of 2014, over 5 million people in the United States live with Alzheimer's. One out of every eight people over 65 has the disease, as well as approximately half of all people over 85.
One out of every three people 65 or older die of some type of dementia, according to OpenPlacement. Dementia is an umbrella term for a variety of conditions, including Alzheimer's disease, notes Stettinius. Dementia is the sixth leading cause of death in the United States, but it is the only cause within the top 10 that has no means of prevention, no way to slow its progression and no cure, states OpenPlacement.
From 2010 to 2030, the number of incidences of dementia worldwide is expected to double, with 65.7 million people suffering from the disease in 2030. The number is expected to double again in 2050 with 115.4 million people diagnosed worldwide. The estimated cost to care for people with dementia in the United States was $203 billion in 2013; the amount in 2050 is anticipated to total $1.2 trillion, explains OpenPlacement.
