Reports about memory loss, forgetfulness and confusion span all statin drugs and all age groups of patients, the F.D.A. said. Dr. Egan said the reports were rare, but those affected often feel “fuzzy” or unfocused in their thinking.
The symptoms generally were not serious and went away within a few weeks after patients stopped taking the medications. Some people affected had been taking a statin for a day, others for years.
Before anyone is prescribed a statin, they should have a brain imaging study to provide a reference point of cognitive functioning.
If any side-effects develop, another brain imaging study would show it when compared to the pre-statin one.
And as far as I’m concerned, the side-effect is permanent. I can’t prove it — because I don’t have the set of images I suggest — but my short-term memory is not as good as it was before I encountered a statin.
