“How long does anesthesia affect your memory?”

Unless you have brain damage from cardiac arrest, I am not sure there is a long term memory loss.

In general, you should feel pretty clear headed after anesthesia pretty quickly. Depending on whether you get sedation or general anesthesia it will take a short time for the medication to be inactivated or cleared from your system. We recommend not driving, signing contracts, or taking a math test fir 24 hours because higher cognitive centers are the last to recover. Rarely, patients may experience some cognitive symptoms for a few days to a few weeks. This does not usually interfere with daily activities. Short term memory going to long term memory is definitely at risk until you are fully recovered. At your age and assuming no medical issues, it will be a very quick recovery. Good luck!

Only for the duration that the medicine is in your system, typically 1-2 hours after your procedure. Older people can have a condition called post-op cognitive dysfunction that can last much longer.

General anesthesia does not usually affect the memory of a healthy 29-year-old.

General anesthesia affects thinking and memory for at least 24 hours. If you have had a general anesthetic lasting more than 2 hours, you probably should not make any important decisions for 48 hours. The above answer would only apply to a healthy young person. Older, medically unhealthy, and obese patients may take longer to clear anesthetics from their bodies.
