“Many governments are woefully unprepared for an epidemic of dementia currently affecting 44 million people worldwide and set to more than treble to 135 million people by 2050, health experts and campaigners said on Thursday,” Reuters reports. “Fresh estimates from the advocacy group Alzheimer’s Disease International (ADI) showed a 17 percent increase in the number of people with the … condition compared with 2010, and warned that by 2050 more than 70 percent of dementia sufferers will be living in poorer countries,” the news service writes. “Leaders from the Group of Eight (G8) industrialized countries are due to meet in London next week for a special summit on dementia — a condition that includes Alzheimer’s, vascular dementia, dementia with Lewy bodies (DLB), fronto-temporal dementia and many other causes of cognitive decline,” the news service notes (Kelland, 12/4).
