Dementia cases 'to almost triple by 2050' - RTE

The number of adults living with dementia worldwide is expected to nearly triple, from an estimated 57 million in 2019 to 153 million in 2050, according to a study.

Researchers suggest this is due to population growth and population ageing.

• They looked at four risk factors for dementia - smoking, obesity, high blood sugar, and low education - and the impact they will have on future trends.

For example, improvements in global education access are projected to reduce global dementia prevalence by 6.2 million cases by 2050.

But this will be countered by anticipated trends in obesity, high blood sugar, and smoking, which are expected to result in an additional 6.8 million dementia cases.
