MRI Maker of Perioperative Neurocognitive Disorder

Conditions
Knee Osteoarthritis
Necrosis of Femoral Head
Fracture of Lower Limb
Registration Number
NCT03773627
Lead Sponsor
RenJi Hospital
Brief Summary

Periperative neurocognitive disorder(PND) is consistently associated with increased morbidity and mortality, but its mechanisms remain unclear. Moreover, valid biomarkers for the prediction or diagnosis of the development of delayed neurocognitive recovery in aged patients have not been identified so far. The purpose of this study is trying to find the functional MRI marker of PND.
