I have had long Covid since 2020. Last year I had 3 surgeries within 5 months - 2 with sedation and one with general anesthesia. It definitely affected my cognition. I had increased brain fog, trouble with word finding and difficulty putting sentences together, in general more confusion. My long Covid nurse practitioner assured me that this was a normal reaction after having sedation and anesthesia. It took about 3 months after the last surgery to improve back to where I was cognitively before the surgeries.
