“…They found a reduction in both frequency and amplitude of the α rhythm, the normal rhythm in an awake and alert person, for a period of up to 2 weeks after the trial. 2 In addition to general anesthetics, perioperative administration of analgesics and sedatives may also have an adverse effect on cognitive function. The impairment of memory during the first hours after surgery is therefore rather predictable but should nevertheless be given attention by the surgeon when informing the patient of surgical findings, future prognosis, and postoperative counseling.…”

Postoperative cognitive dysfunction (POCD) is a subtle impairment of memory, concentration, and speed of information processing. It is a frequent complication following surgery and can have a debilitating effect on patients' recovery and future prognosis. Neuropsychological testing is needed to reveal postoperative cognitive decline, and questionnaires are not useful for this purpose. There is a profound lack of consensus regarding the research methodology for detection of cognitive deterioration, especially the diagnostic criteria. Issues, such as baseline performance, learning effects, and the interval between test sessions, also influence test results and must be considered when designing and interpreting POCD data.
