The NHS says that there are five types of statin available on prescription in the UK. They include atorvastatin, fluvastatin pravastatin, rosuvastatin and simvastatin.
A study for the National Center for Biotechnology Information published in the U.S. National Library of Medicine says that although randomised controlled trials have not confirmed cognitive impairing effects with statins, “continuing evidence suggests statins have the ability to cause reversible cognitive impairment in some patients”.
It adds: “Paradoxically, statins have also been shown to decrease the risk of dementia, Alzheimer’s disease, and improve cognitive impairment in some cases.”
The Food and Drug Administration (FDA) previously recognised statins may cause reversible cognitive impairment.
