Diabetes complications linked to dementia in older US adults
The estimated share of dementia cases attributable to measured risk factors was 11.1%, compared with 45.2% in the Lancet estimate.
Our read
Populations- Studied:
- Cohort study of 83,370 adults older than 50 without prior dementia
- What changed:
- Dementia risk was higher with several diabetes-related complications, including neuropathy, stroke, and chronic kidney disease
- The catch:
- Other health and social differences may have influenced links with diabetes and its complications
- In the record:
- The 16th paper on lower education with results in people; 22 on record in all.

Among 83,370 US adults older than 50 without prior dementia, an observational cohort study examined 12 potentially modifiable risk factors. Researchers used electronic health records and surveys from the All of Us Research Program, adjusting estimates for the other measured factors.
Lower education, smoking, diabetes, obesity, high blood pressure, traumatic brain injury, depression and social isolation were associated with dementia risk. Several diabetes-related complications had independent links, including nerve damage, stroke and chronic kidney disease. The combined population-attributable fraction—a statistical estimate of the share of cases attributed to the measured factors—was 11.1%, below the Lancet estimate of 45.2%. Adding diabetes-related complications left that total essentially unchanged, at 10.7%.
Why it matters
Dementia prevention in later life depends on understanding how potentially modifiable risks overlap. The analysis addresses where diabetes-related complications fit within that combined burden.
Caveats
Other health and social differences may have influenced the links with diabetes and its complications, so these estimates do not measure prevention benefits. The analysis covered 12 of 14 framework risk factors in adults older than 50 without prior dementia.
