Often, surgery that involves the chest uses deep anesthesia to suppress breath movements to a minimum. I suggest you talk with the anesthesiologist about the depth of anesthesia and any options available to reduce the risk of anesthesia "chemo brain." If the anesthesiologist tries to discount any risk, shop around for another anesthesiologist for advice. I took months to recover from general anesthesia when I had minimal but full sedation for knee and ankle surgery. Two surgeries 12 months apart left me struggling for quite some time.

I suggest you get on a brain nutrition regimen like the one I list in the Vitamins sticky at the top long before the surgery. You want your brain to be as healthy as possible before undergoing anesthesia. B's, folic acid, D3, Omega 3 DHA, etc will strengthen your brain and the blood brain barrier.

I would not consider a neuro's 'all clear' opinion to be worth much. Very few accept the subtle but very real struggles we have.
