for some years I have experienced short term memory loss with episodes of migraine. Have taken Simivastatin for a couple of years for family history of stroke/heart attack. Am 58 years of age and blood test prior to Simvastatin revealed levels of Had cholecstectomy last June. Experienced first dramatic episode of memory loss just prior to operation. It lasted for 35 days and by the end, apart from being exhausted could barely cross the road or go out of the house. Experienced anxiety and problems with peripheral vision. Was also on mmedication for high blood pressure. Stopped taking this and problems with memory seemed better but have now returned. Have just had 10 day bout with mood swings, anxiety, etc and husband and I both exhausted. Have read that statins can cause memory loss. Because I'm a migraneur STM and assoc problems have, by myself and practitioners been attributed to this. But not so sure. Please can you advise. Thank you. Deborah Hammond
