My short term memory is gradually getting worse and worse, I have moments of confusion where I can't remember where I was going, or why. I used to be very confident and outgoing, now I avoid social gatherings because I feel anxious, and I have lost the last 4 jobs because I cannot retain infomation during training. I am a financial disaster which is not great because I will be 65 this year. Is my brain messed up permanently? I was very bright as a university student..and now I can't even manage a call center. Is this common?
