Cognitive dysfunction 1–2 years after non‐cardiac surgery in the elderly

Background: Postoperative cognitive dysfunction (POCD) is a well‐recognised complication of cardiac surgery, but evidence of POCD after general surgery has been lacking. We recently showed that POCD was present in 9.9% of elderly patients 3 months after major non‐cardiac surgery. The aim of the present study was to investigate whether POCD persists for 1–2 years after operation.
