I think the medical profession quite a few years ago first started noticing cognitive decline in heart patients after long surgeries. It wasn’t clear then what the issue was; some thought it was because of trauma to the heart itself. It slowly became clear that any procedure in which the patient was anesthetized for a long period had the same effect.
I’m optimistic that the developments in this article prove useful.
Thanks. Nobody told us in advance what the possibly cognitive outcome would be for Dad. We all expected him to be himself after the surgery, but he was never the same. He was young, too. He did improve quite a bit post-op and started hitting the gym. But his Parkinson’s got a lot worse and it wasn’t bad before all of his muscles just would not work any more. It was a brutal end to a strapping, strong, vibrant man.
