Statins can reduce dementia risk by up to 15%, long-term study suggests
Source: Guardian Health ↗
A 15‑year Danish cohort study involving 132,585 individuals with type‑2 diabetes found that initiating statin therapy was linked to a lower likelihood of developing dementia, with early treatment reducing risk by 15% and later treatment by 10% over a decade. The research, presented at the European Society of Cardiology’s annual congress in Munich and published in Lancet Regional Health Europe, tracked participants from 2006 to 2021 and observed that only 2.7% of the cohort developed dementia during the follow‑up period. The findings were consistent across both sexes, underscoring the potential of widely used, inexpensive cholesterol‑lowering drugs to impact brain health.
The study builds on a broader understanding that high low‑density lipoprotein (LDL) cholesterol contributes to vascular damage that can impair cerebral blood flow, a recognized risk factor for dementia. Experts cited the Lancet dementia commission’s recommendation that addressing modifiable risks—such as elevated LDL—from midlife could prevent or delay up to 45% of cases. Dr Tummas Ternhamar of Copenhagen University Hospital emphasized that the timing of LDL‑C management matters, suggesting that early statin use may be more protective than later intervention. The proposed mechanism links statins’ ability to curb atherosclerosis and improve vascular health with reduced cerebrovascular injury, thereby potentially safeguarding brain tissue from ischemic damage.
Commentators highlighted both the promise and the limitations of the observational design. While Dr Honorine Lebraud of Alzheimer’s Research UK noted the study adds to evidence that cardiovascular and brain health are intertwined, she called for further research to establish a direct causal link. Prof Bryan Williams of the British Heart Foundation cautioned that association does not prove causation, though he acknowledged that randomized trials have also suggested a dementia‑risk reduction with statins. The results may inform future public‑health strategies that incorporate statins into a broader preventive package—including physical activity and diet—to curb the projected rise in dementia cases, which could reach 153 million worldwide by 2050.
