Dementia has mostly been a rich-world sickness, because it becomes more common as people live longer. China is fast catching up. Life expectancy increased from 45 in 1960 to 77 now, and the population is aging rapidly: one person in six is over 60 now; by 2025 nearly one in four will be. Factors that increase the risk of developing dementia are also on the rise, including obesity, smoking, lack of exercise and diabetes.
