Although postoperative cognitive dysfunction (POCD) is common among the older adults after surgery, the extent to which exposure to surgery and anesthesia, preexisting conditions, and other factors contribute to POCD is unclear. The current study was designed to examine the association between exposure to surgery and subsequent level of cognitive functioning in a very large population (8503) of middle-aged and elderly twins in Denmark with almost complete surgery records since 1977.
