The Claim
High fasting glucose and high body mass index (BMI) are associated with a significant proportion of dementia-related disability and death globally among adults aged 65 and older, accounting for 1,638 and 833 DALYs per 100,000 population in 2021, respectively, with both showing increasing trends over time.
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.
Among adults aged 65 and older, high fasting glucose and high body mass index are linked to a large number of dementia-related disabilities and deaths worldwide, with these conditions contributing 1,638 and 833 disability-adjusted life years per 100,000 people in 2021, and both contributions have risen over time.

High blood sugar and excess body fat cause the brain to accumulate toxic proteins and become inflamed, while blood flow to the brain decreases. This damages brain cells, prevents cleanup of waste, and leads to memory loss and dementia.
What the research says
1 studyThis study found that being overweight and having high blood sugar are big reasons why older adults lose healthy years to dementia, and these problems have gotten worse over the past 30 years — just like the claim says.
