Brief summary

This study aims to investigate if, following anaesthesia related healthcare inteventions, individuals with higher levels of inflammation at baseline, have a higher rate of postoperative cognitive dysfunction at 3 months after surgery. Participants will be having surgery with an expected stay of 3 or more days and consent to neuropsychological testing and having bloods taken during their hospital stay. Cognitive and memory testing will take place prior to surgery and at 3 months after surgery. Tests for delirium will also be conducted during the participants time in hospital.

Interventions

Observation study of elderly patients (60 years and older) undergoing healthcare interventions requiring surgery and anaesthesia. Patients will undergo baseline and 3 month neuropsychological testing prior to and following surgery. The two neuropsychological tests take roughly one hour and are completed at the patient's home. During the hospital stay patients will have blood samples taken prior to anaesthetic induction, at 30 minutes post surgical incision and also at 6, 24 and 48 hours followin
