I been on atenolol 100mg daily in divided doses for years now, plus quite a bit of other medications I',m 45 and I used to have a phenomenal memory , but my memory is very poor for the last 3 years, its almost embarrassing I can be having a conversation and actually have to ask the other person/s would we were discussing, I don't if its the atenolol but I know oothers on atenolol with similar experiences of course thats a small price to pay for the benefits i get from it in my opinion.
I don't think atenolol can usually cause memory loss. It is less lipophilic than propranolol and is excreted by the kidneys besides.
