Postoperative cognitive dysfunction (POCD) is a decline in cognitive function (especially in memory and executive functions) that may last from 1–12 months after surgery, or longer. In some cases, this disorder may persist for several years after major surgery. POCD is distinct from emergence delirium. Its causes are under investigation and occurs commonly in older patients and those with pre-existing cognitive impairment.

| - Die postoperative kognitive Dysfunktion (POCD) (engl. 'PostOperative Cognitive Dysfunction (POCD)) ist eine Störung der Kognition nach einer Operation. Zum Erkennen der Dysfunktionen bedient man sich einer Testbatterie, die die verschiedenen Domänen der Kognition (z. B. Gedächtnis, Lernen und Konzentrationsfähigkeit) abdeckt. Man vergleicht die Werte präoperativ und postoperativ mit einer Vergleichsgruppe ohne Operation aber mit dem gleichen Zeitintervall, um den Lerneffekt zu kompensieren. (de)

So wurde zum Beispiel als ein Test der Batterie von ISPOCD (International Study of PostOperative Cognitive Dysfunction) der von John Ridley Stroop entdeckte Stroop-Effekt getestet. (de)
- Postoperative cognitive dysfunction (POCD) is a decline in cognitive function (especially in memory and executive functions) that may last from 1–12 months after surgery, or longer. In some cases, this disorder may persist for several years after major surgery. POCD is distinct from emergence delirium. Its causes are under investigation and occurs commonly in older patients and those with pre-existing cognitive impairment. The causes of POCD are not understood. It does not appear to be caused by lack of oxygen or impaired blood flow to the brain and is equally likely under regional and general anesthesia. It may be mediated by the body's inflammatory response to surgery. (en)
