Surgery, anaesthesia may affect memory, says study

Turns out, surgery and anaesthesia can slightly affect memory of patients. According to a new study, patients may score slightly lower on certain memory tests after having surgery and anaesthesia. In the study of 312 participants who had surgery and 652 participants who had not (with an average age in the 50s), surgery between tests was associated with a decline in immediate memory by one point out of a possible maximum test score of 30 points. The findings from the study are published in the journal Anaesthesia.
