New York, Jan 9 (TIWN) Dementia cases are expected to rise by over 150 million by 2050, which is about three times more than in 2019, suggests a new study.

Globally, the number of people affected by dementia was estimated to have increased by 117 per cent between 1990 and 2016, largely due to population aging.  Demographic analyses suggest that these patterns are driven by decreases in fertility coupled with increases in life expectancy, which together lead to large changes in the age structure of the population.  These changes, along with largely stable age-specific prevalence estimates and population growth, lead to large increases in the number of people affected by dementia.  Given that these demographic trends are expected to continue into the future, the number of people with dementia will continue to rise, the study said.  Additionally, evidence has emerged supporting the importance of potentially modifiable risk factors for dementia.
