Health Care: According to a new cohort study, the number of people living with dementia is anticipated to increase by more than 150 million by 2050, which is around three times the number in 2019. According to the research, the number of persons with dementia will rise from 57.4 million cases in 2019 to 152.8 million cases in 2050, as per The Lancet Public Health journal.

The researchers noted, "we projected that there were more women with dementia than males with dementia globally in 2019, and we predict this pattern to continue through 2050."  Between 1990 and 2016, the number of people affected by dementia was expected to have increased by 117% globally, owing mostly to population ageing.

Demographic assessments imply that these patterns are driven by lower fertility combined with higher life expectancy, resulting in major shifts in the population's age structure. These developments, together with relatively unchanged age-specific prevalence estimates and population expansion, have resulted in significant increases in the number of dementia sufferers.

The number of persons with dementia is likely to climb in the future as a result of these demographic changes, according to the study. Furthermore, research has developed that supports the importance of possibly modifiable dementia risk factors.
