Abstract
Answer C. Postoperative cognitive dysfunction (POCD)
Unlike postoperative delirium, which presents in the first few days after surgery, postoperative cognitive dysfunction (POCD) can develop in weeks to months after surgery. Patients report increasing difficulty with behaviour, memory and complex mental functioning. The cause of postoperative cognitive dysfunction is unclear, but suggestions include reduced blood pressure during surgery, increased stress levels while in hospital, genetic susceptibility and increased inflammation in the body. Recovery can take months to years and there is evidence that there may be some lasting effects in a few people. GPs can help to support patients by reassurance, considering social problems and offering formal assessment of their cognitive function with onward referral to memory clinics if necessary.
