# Statin use and dementia risk in diabetes patients > Live situation record from CLSTR: https://clstr.news/situations/statin-use-and-dementia-risk-in-diabetes-patients > Updated: 2026-09-02T20:35:42.000Z. Sources: 7. Developments: 2. A large-scale Danish study involving over 132,000 individuals suggests that statin therapy may reduce the risk of dementia in patients with type 2 diabetes. The research, published in The Lancet Regional Health – Europe and presented at the European Society of Cardiology Congress, indicates that the timing of treatment is a critical factor in cognitive protection. Patients who initiated statin therapy within one year of their type 2 diabetes diagnosis experienced a 15% lower risk of dementia. Those who began treatment between one and five years after diagnosis saw a 10% reduction in risk. Researchers suggest the benefit may stem from lowering low-density lipoprotein (LDL) cholesterol, which helps prevent the narrowing or hardening of blood vessels supplying the brain. While the study shows a strong association, experts emphasize that further research is needed to establish direct causation. However, the findings are considered significant for public health due to the widespread availability and low cost of statins. ## Timeline ### 2026-09-02: Statins may reduce dementia risk in patients with type 2 diabetes A Danish study published in The Lancet suggests that early statin use in patients with type 2 diabetes can reduce dementia risk by up to 15% by managing LDL cholesterol levels. 4 sources. https://clstr.news/cluster/statins-linked-to-reduced-dementia-risk-in-diabetes-patients ### 2026-08-31: Statins linked to lower dementia risk in type 2 diabetes patients A Danish study published in The Lancet Regional Health – Europe indicates that starting statins within one year of a type 2 diabetes diagnosis can reduce dementia risk by 15%. 3 sources. https://clstr.news/cluster/statins-linked-to-lower-dementia-risk-in-diabetes-patients --- Cite as: Statin use and dementia risk in diabetes patients.
