China: Over 9 million people with dementia

29 Sep

I came across a blog post claiming that there are 5 million people with dementia in China. I was skeptical at first but found substantiation at the highly regarded New Scientist Health blog.

The post cites WHO data:

“In 2010, China had more people living with Alzheimer’s disease than any other country in the world – and twice as many cases of Alzheimer’s and other kinds of dementia as the World Health Organization thought.

Cases of all kinds of age-related dementia in the country rose from 3.7 million in 1990 to 9.2 million in 2010.”

This rapid increase may be related to increasing life expectancy, high levels of smoking, environmental pollution,  and the adoption of unhealthy western diet and sedentary life style.

Of course, China is a a very populous nation and one percent translates into 10,000,000 people. So, dementia is still under one percent in China, but the absolute number is quite large.
