Chronic Pain and Postoperative Cognitive Function in the Elderly: a Prospective Observational Study

Brief description of study

The purpose of this study is to explore how chronic pain and surgery affects brain function and cognition in the elderly, in order to identify those at risk of developing post-operative cognitive dysfunction (POCD). As part of the evaluation, we will use a series of well-established measures, including pain questionnaires, cognitive assessment tests, blood sampling and modern imaging techniques to quantify POCD. We are asking you to take part in this research study because you match the inclusion criteria and are scheduled to have surgery.
