’ . . . .my memory got impaired due to gen. anesthesia almost 2 yrs ago.’
I experienced the same thing after surgery. But it does get better eventually, especially if you are active.
It was really severe right after, then a cancer drug had horrible side effects including affecting cognizance. I stopped it. Taking herbs that help. I’m as active as I can be in my situation. No more surgery for me, ever, no matter what.
