The Claim

In 2021, Alzheimer's disease and other dementias caused 8.02 million deaths and 25.38 million disability-adjusted life years (DALYs) globally among adults aged 65 and older, with women accounting for nearly two-thirds of the total burden.

Description
1 study reviewed
In plain English

See the scientific wording

In 2021, Alzheimer's disease and other dementias caused 8.02 million deaths and 25.38 million disability-adjusted life years (DALYs) globally among adults aged 65 and older, with women accounting for nearly two-thirds of the total burden, highlighting a significant gender disparity in disease impact.

Why this might work

High blood sugar and excess body fat cause the brain to accumulate toxic proteins and trigger inflammation, which kills brain cells and impairs memory and thinking over time.

What the research says

1 study
  1. Study: Global Burden of Alzheimer's disease and other dementias in adults aged 65 years and older, 1991–2021: population-based study

    This study found that in 2021, dementia killed over 8 million older adults and took away 25 million years of healthy life worldwide, and most of those affected were women—because women live longer and are more likely to get dementia as they age.
