Association of sleep and anaesthesia EEG biomarkers with preoperative Montreal cognitive assessment (MoCA) score: A pilot study
Authors' conclusion
Preoperative cognitive impairment appears to be detectable by both EEGsleep and EEGintraop .
Study context
- Population
- Patients undergoing propofol-based GA, assessed with MoCA and sleep EEG 1 day before surgery and intraoperative EEG from depth-of-anaesthesia monitors
- Participants
- 27 patients
- Comparison
- MoCA <25 vs normal MoCA
- MoCA <25n = 11
- Outcome
- Sleep spindle power on EEGsleep, MoCA <25 vs normal MoCA
- Follow-up
- 1 day before GA
Main finding
As reported in the abstract
