Brief Summary:
Perioperative Neurocognitive Disorders(PND) is a common perioperative complication among the elderly, especially in the plastic surgery. Different anesthesia methods have different incidences of PND, but it's still unknow which is better between spinal anesthesia and nerve block combined with general anesthesia. We will apply a psychometric battery test which contain different cognitive domains to estimate the incidence of PND at a week a month and a year after surgery with different anesthesia methods. Study has showed that functional magnetic resonance imaging (fMRI) could detect a cognitive decline through spontaneous neuronal activity in the cortex and hippocampus. In our study, multi-mode imaging technology is used to conduct in-depth research on MRI and make correlation analysis with cognitive function.
