China has world’s fastest rise in dementia with up to 115 million cases forecast by 2050

China has the world’s fastest growing number of cases of dementia with the number of diagnosed cases increasing threefold over the past three decades, a new study has warned.

In 1990 the country had about 4 million patients with dementia, a number that rose to 17 million by 2021 and is projected to reach 115 million by 2050, according to the research published in PLOS One earlier this month.
