Anesthesia related cognitive decline, specifically dysnomia

I am a 73yo woman who retired 18 mos ago.
Almost exactly a year later, a pulmonary nodule we had been following in annual lung screening CTs as it slowly increased from 6mm to 14mm over 4 years, and at that last size the pulmonologist and cardiothoracic surgeon determined it was time to remove it in a wedge resection if it proved benign, followed by lobectomy if malignant. While that determination was made I remained under anesthesia. So in my case, it was quite a while.

Since the surgery i have slowly become
Aware that I have a material decline in specific brain function. It’s not as if I have a global cognitive decline. I don’t seem to have decline in executive function for instance.
But I have significant dysnomia. Not just names of people - rather names of “things” - but it’s easier to describe as a word to reference anything that functions as a label or reference term. Like names of diseases or an object. Virtually anything.

I had meetings over last couple of days with a hand surgeon to discuss surgery for duypuytren contracture (I have RA) and I inquired whether it could be done under a local nerve block and we got into a discussion about anesthesia related cognitive issues. He said that it sometimes takes more than a year for “brain fog” to clear. I guess fog is a good term, for I have become relatively sedentary and withdrawn since the surgery.

Concurrently I find that as a 73 yo patient, I am discounted and some docs - not all thank goodness - show little effort to even appear engaged. I have found a couple of Docs
- the hand surgeon and a new oncologist - who will discuss it.
So in that context I’d like to ask if any of you are experiencing cognitive or personality issues following general anesthesia? Am I a population of One, or a member of a much larger population?
