By the middle of the century, the number of older people suffering from Alzheimer's and other forms of dementia will nearly triple, severely straining caregiving resources, the charity Alzheimer's Disease International says in a new study released Thursday.
Currently, some 100 million people globally suffer from the potentially fatal disease. That number is expected to increase to 277 million by 2050, as the graying population increases, The World Alzheimer's Report 2013 says.
As NPR reported in May, the number of Americans with Alzheimer's disease is expected to triple by 2050. But studies published in the last two weeks based in European countries show signs of declining dementia.
Right now, 5 million Americans have Alzheimer's disease and other dementias. One of them is 73-year-old Pansy Greene. She's in the early stages of Alzheimer's, and she and her husband, Winston, want people to know that so far, their daily lives have changed little despite the diagnosis.
