@marield65, I would like to extend my welcome to you. I am happy that Colleen has brought me into this discussion. I can assure you that you are not alone asking this question or dealing with this concern. I will be happy to share whatever I have gained from my experience. I did experience some memory lapses after surgery. And it was frightening and confusing for me. Fortunately I had my husband at my side, so I was not really fearful in the physical sense.
I am looking forward to hearing from you.
Rosemary
