thank you iam on 5mg crestor a day which i no is not very much but as i have had 2 grand mal seizures which have effected my memory lobes iam relucted to continue to take it for much longer.I had a grand mal at 48 years old another at 62 years old iam now 65 years old and iam on 1200mg tegretol a day . My memory is getting worse and i really dont want any medication that will make it that way which i hear crestor can do. I eat healthy never eat sweets,cakes,biscuits,ice cream as iam a savoury eater and am going to have my blood tested next week for tegrotol levels,chloresterol which was 4.1 last year and i no one needs chloresterol for the brain to be healthy.I really mean my memory is bad as i now find it hard to remember words to use when iam talking,peoples names,reading a book,i have to ask hubby so many questions.I no this is a big ask but just to answer if crestor can cause memory loss will be a help to me thank you.
