Global dementia cases set to triple by 2050 unless countries address risk factors

The number of adults (aged 40 years and older) living with dementia worldwide is expected to nearly triple, from an estimated 57 million in 2019 to 153 million in 2050, due primarily to population growth and population ageing. The Global Burden of Disease study is the first to provide forecasting estimates for 204 countries worldwide, and is published in The Lancet Public Health.
