Statins cause memory loss

RecordOBS-0317
CategoryHealth/Vaccines
StatusDEBUNKED
SummarySome claim that statin drugs cause memory loss and cognitive impairment. This concern was fueled by FDA label changes in 2012 based on anecdotal reports. Rigorous studies have found no evidence that statins commonly cause memory loss.
OriginThe FDA changed statin labels in 2012 after receiving reports of memory loss and confusion from some users.
Claimed
  • Statins cause memory loss and confusion.
  • Statins increase the risk of dementia.
Evidence / consensusLarge, rigorous studies show no effect on thinking and memory. Some evidence suggests statins may even have a beneficial effect on brain health by preventing strokes.
> OBSERVER NOTE:
The FDA label change was based on weak evidence. Subsequent high-quality research has not supported a causal link.
