The Claim
From 1991 to 2021, the global age-standardized mortality rate from Alzheimer's disease and other dementias among adults aged 65 and older increased by 115%, from 6.5 to 14 deaths per 100,000 population, with an average annual increase of 1.10%.
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.
Between 1991 and 2021, the number of deaths from Alzheimer's disease and other dementias per 100,000 people aged 65 and older rose from 6.5 to 14, reflecting a 115% increase over that period.

From 1991 to 2021, global age-standardized mortality from Alzheimer's disease and other dementias among adults aged 65 and older increased by 115%, from 6.5 to 14 deaths per 100,000 population, with an average annual increase of 1.10%, reflecting growing disease burden despite advances in medical care.
High blood sugar and excess body fat cause the brain to accumulate toxic proteins and reduce blood flow, which kills brain cells over time and leads to dementia.
What the research says
1 studyThis study found that more older people are dying from Alzheimer’s and dementia each year than before, exactly as the claim says—up 115% since 1991—because more people are living longer, even though medicine has improved.
