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, according to researchers from Johns Hopkins University.


  • 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.
  • A recent study estimates the Alzheimer's toll in the United States will reach 16 million by 2050, compared with more than 5 million today.

Estimates for other regions include Africa, with an estimated 1.3 million cases today and 6.3 million in 2050; Europe, 7.2 million and 16.5 million; Latin America and the Caribbean, 2 million and 10.8 million, and Oceania, 200,00 and 800,000, respectively.
