NCT02275026

Brief Summary

The purpose of this study is to understand how elderly individuals regain their cognitive skills following general anesthesia. The investigators will compare an age stratified group of volunteers who will be evaluated with a series of cognitive tests and a functional MRI. The participants will then be administered general anesthesia for two hours. The investigators will then assess the participants using state of the art tools to determine when participants return to their cognitive baseline.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants Recovered on Postoperative Quality of Recovery Scale (PQRS)

    Cognitive Function using scales of the PQRS to test whether age is associated with the time of return to baseline cognitive function. The PQRS is a brief measurement tool to assess multiple domains of recovery, including cognition, over time. It is scored as recovered / not recovered based on level of performance, within a certain tolerance range, relative to preoperative (baseline) performance - before the general anesthesia / MRI scanning session. Postoperative Quality of Recovery Cognitive Scale at each study timepoint by age decade. Postoperative Quality of Recovery Cognitive

    15 min, 60 min, 1 day, 3 days, 7 days, 30 days, 6 months

Secondary Outcomes (1)

  • Change in NIH Tool Box Composite

    Baseline, 1 day, 7 days, 30 days

Study Arms (1)

Functional magnetic resonance imaging

EXPERIMENTAL

Magnetic resonance images will be acquired on a 3 Tesla scanner (Skyra, Siemens, Erlangen, Germany) with a 20 channel receiver coil.

Procedure: Functional magnetic resonance imaging

Interventions

Diffusion tensor imaging

Also known as: fMRI
Functional magnetic resonance imaging
