Liu JM, et al. - Authors assessed the correlation of statin use and dementia in patients with type 2 diabetes mellitus (T2DM) receiving androgen deprivation therapy (ADT). They used the National Health Insurance Research Database of Taiwan to conduct a population-based nationwide cohort study of T2DM patients newly diagnosed with prostate cancer (PCa) between 1998 and 2013. In T2DM patients receiving ADT for PCa, statin use led to decreased risk of dementia (with an absolute risk reduction by 1%), with statin adherence and intensity augmenting this benefit.
