Can surgery and anaesthesia affect memory?

Preliminary findings suggest it may indeed be the case

Surgery and anaesthesia appear to have a negative impact on memory in middle-aged people, according to researchers.

Data from an analysis of almost 1000 people in their 50s who are cognitively unimpaired show that those who have had surgery and anaesthesia are at risk of small reductions in performance on neuropsychological tests of memory and executive function.
