The number of people living with dementia is expected to double to 65.7 million by 2030 and more than triple by 2050, with "the [current estimated] cost of treating and caring for those with the condition at $604 billion a year," according to a report released Wednesday by the WHO and Alzheimer's Disease International, Agence France-Presse reports (4/11). "Dementia affects people in all countries, with more than half (58 percent) living in low- and middle-income countries," and "[b]y 2050, this is likely to rise to more than 70 percent," according to a WHO press release.
