Starting Statin Therapy Early May Lower Dementia Risk for Diabetes Patients
Initiating statin therapy soon after a type 2 diabetes diagnosis may offer benefits beyond heart protection. A study presented at the European Society of Cardiology Congress on August 30 suggests a potential link to reduced dementia risk. The research showed that adults who began statin treatment within a year of being diagnosed with type 2 diabetes experienced a 15% lower relative risk of developing dementia over a decade compared to those who waited more than five years to start the medication.
For individuals delaying statin use between one to five years, the reduced relative dementia risk was 10%, as reported in The Lancet Regional Health – Europe.

Statins, prescribed to lower ‘bad’ LDL cholesterol, contribute to reducing the risks of heart attacks and strokes. Researchers conducted the study by analyzing health data from 132,585 patients in Denmark diagnosed with type 2 diabetes from 2006 to 2019, who had no history of statin use or dementia.
During a median follow-up period of 7.1 years, the study examined the effects of statin treatment timing on overall dementia rates.
Dr. Liron Sinvani, a geriatrician and research director at the Northwell Institute for Healthy Aging in New York, highlighted the study’s value in supporting the protective brain health effects of statins.
She emphasized that a 15% improvement, while modest, is significant for brain health. People with type 2 diabetes face heightened risks of cognitive decline and heart disease.
The study also explored the relation between treatment timing and dementia risk. Early statin usage correlated with a lower dementia risk than delayed treatments.
“The message here is that maybe waiting is actually not the right approach,” Sinvani suggests.
Dr. Sinvani described the results as particularly convincing, noting the association with reduced vascular dementia, rather than Alzheimer’s, supports the biological role of statins in lowering cholesterol and inflammation, and protecting blood vessels.
The research underscores the importance of timely statin therapy as part of a broader health approach, including regular exercise, a healthy diet, and maintaining social connections. As an observational study, it highlights an association rather than proving direct causation between statins and dementia prevention.
The Lancet Commission estimates that addressing modifiable risk factors could prevent or delay nearly half of dementia cases.
Despite the study’s limitations, Dr. Sinvani encourages diabetes patients without current statin prescriptions to consult their doctors about potential benefits.
