Given the possible link among oxidative stress and neurocognitive dysfunctions, we hypothesized that dynamic thiol-disulfide homeostasis could be an early predictor of cognitive impairment in cardiac surgery in parallel to the changes in cerebral oxygenation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Seventy-one patients undergoing elective coronary artery bypass graft (CABG) surgery were prospectively studied.
