Global dementia cases projected to more than double by 2050
A global study led by researchers from the University of New South Wales projects that annual new cases of dementia will more than double by 2050. Based on data from over 38,000 individuals across 18 countries and territories, the research estimates that new cases will rise from 11.4 million in 2023 to 24.7 million annually by 2050.
The total number of people living with dementia is expected to reach nearly 150 million by mid-century. The study, published in JAMA Neurology, highlights significant disparities in incidence rates. Women and residents of low- to middle-income countries are expected to face higher rates of the disease compared to men and those in high-income nations.
Researchers emphasize that population ageing will place immense pressure on health systems, families, and global economies. Experts are calling for urgent investment in prevention, earlier diagnosis, and improved care to mitigate the projected burden.
