Research published in The Lancet journals indicates that early statin use may be linked to a 15% reduction in dementia risk among individuals with type 2 diabetes. An observational study utilizing Danish national health registers tracked over 132,000 people, suggesting that the protective effect against dementia was most significant when treatment began shortly after a diabetes diagnosis.

Researchers noted that while the findings highlight potential vascular benefits for brain health, a direct causal link cannot be proven due to potential confounding factors, such as the “healthy-user effect.”

In related studies regarding elderly populations, a French trial involving 1,180 participants aged 75 and older found that stopping statin treatment did not meaningfully worsen survival rates over a three-year period for those without a history of heart disease or stroke. The study reported a 7.2% mortality rate in the group that stopped treatment compared to 7.9% in the group that continued.
