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.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In 2021, Alzheimer's disease and other dementias resulted in 8.02 million deaths and 25.38 million disability-adjusted life years worldwide among people aged 65 and older, and nearly two-thirds of this burden occurred in women.

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 studyThis 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.
