Could statin drugs cause dementia

Hi, my grandmother is becoming more and more lost, not knowing even her closest family. This could be because of her age (83) or a side effect of Atoris?

Hi, I have very bad experience with amnesia and I believe it’s due to Lipitor. When I went to jogging one morning, I came back without being able to find my way home. In the end neighbors found me and brought back home. After some time I was diagnosed with dementia. It took me a while to come back to normal state. I couldn’t realize it was due to drug, statins until I heard in some TV show about this side effect of statins. So, I stopped taking them any longer. You must weight carefully, is it worth becoming useless in exchange for low cholesterol levels. I decided to search for new ways to control cholesterol level.
