No association found between late-in-life surgery and long-term cognitive decline

Beskrivelse

Undergoing surgery later in life is not associated with an increased risk of long-term cognitive decline, according to the results of a large twin study involving more than 8,500 middle-aged and elderly Danish twins. The study, which was published this week in the journal Anesthesiology, is the latest in a growing body of research that appears to debunk the idea that the use of general anesthesia during surgery leads to what has been referred to as persistent postoperative cognitive decline (POCD).
