Global dementia cases may triple by 2050: Study

Each year, an estimated 10 in every 100,000 individuals develop dementia with early-onset (prior to age 65). This corresponds to 350,000 new cases of early-onset dementia per year, globally.

New York: The number of people with dementia will nearly triple to more than 152 million by 2050, researchers estimate, based on anticipated trends in smoking, high body mass index and high blood sugar levels observed among people. The study, led by researchers at the University of Washington School of Medicine, forecast dementia prevalence attributable to smoking, high body mass index (BMI) and high fasting plasma glucose, using the expected relationship between these risk factors and dementia prevalence. They found an increase of 6.8 million dementia cases globally between 2019 and 2050 due specifically to expected changes in these risk factors.
