Early Statin Use After Diabetes Diagnosis Linked to Reduced Dementia Risk

At the European Society of Cardiology Congress in Munich, investigators presented data from a Danish cohort of 132,585 adults newly diagnosed with type 2 diabetes, none of whom had used statins or had dementia before. Over a median follow-up of 7.1 years, initiating statin therapy within a year of diagnosis corresponded to a 15% lower relative risk of dementia compared with waiting up to five years, which still showed a 10% reduction.

The effect was most pronounced for vascular dementia, reflecting statins' role in lowering LDL cholesterol, reducing inflammation, and protecting blood vessels. Dr Liron Sinvani of the Northwell Institute for Healthy Aging called the study well-designed and noted that, while observational, it adds to evidence that statins may support brain health. She cautioned that the results do not prove causation and urged patients with diabetes to discuss statin suitability with their doctors as part of a broader lifestyle approach.
