The study investigated the association of statin use and the risk of dementia. Over an average period of 5.3 years, the study analysed 2,798 adults, aged 65 years and older, who were free of dementia at the start of the study.
The study found:
(a) Those who used statins had an 8% increased risk of dementia compared to those who had never used cholesterol lowering drugs.
(b) Those who used statins had an 21% increased risk of Alzheimer's compared to those who had never used cholesterol lowering drugs.
