The Dementia Plague - Technology Review

The Dementia Plague - Technology Review: The latest global demographic analysis, from a World Health Organization report issued earlier this year, paints the dimensions of that slow-motion catastrophe in quick strokes. An estimated 36 million people worldwide currently suffer from dementia; experts predict the number will double, to approximately 70 million, by 2030 and triple by 2050. (China, India, and Latin America in particular face daunting medico-economic crises.) Since the prevalence of the disease doubles with every five-year age increment after 65, projections for 2050 put the total global population at risk for dementia (people 65 or older) at two billion.
