Text Extraction

Postoperative cognitive dysfunction (POCD) is difficult to define. Broadly, POCD refers to deterioration in cognition temporally associated with surgery. While the diagnosis of delirium requires a detection of symptoms, the diagnosis of POCD requires preoperative neuropsychological testing (baseline) and a determination that defines how much of a decline is called cognitive dysfunction. The spectrum of abilities referred to as cognition is diverse, including learning and memory, verbal abilities, perception, attention, executive functions and abstract thinking. It is possible to have a decrement in one area without a deficit in another. Self reporting of cognitive symptoms have been shown to correlate poorly with objective testing, so valid pre and postoperative testing is essential to the diagnosis of POCD. Many elderly patients may have preexisting mild cognitive impairment that has gone undiagnosed.
