WASHINGTON (AP) -- More than 26 million people worldwide have Alzheimer's disease, and a new forecast says the number will quadruple by 2050. At that rate, one in 85 people will have the brain-destroying disease in 40 years, researchers from Johns Hopkins University conclude.

"If we can make even modest advances in preventing Alzheimer's disease, or delay its progression, we could have a huge global public health impact," said Johns Hopkins public health specialist Ron Brookmeyer, who led the new study.

The biggest jump is projected for densely populated Asia, home of almost half of today's Alzheimer's cases, 12.6 million. By 2050, Asia will have 62.8 million of the world's 106 million Alzheimer's patients, the study projects.

A recent U.S. study estimated that this nation's Alzheimer's toll will reach 16 million by 2050, compared with more than 5 million today. The new estimate is significantly lower, suggesting only 3.1 million North American cases today and 8.8 million by 2050.
