Cardiac arrest & resuscitation
Resting state EEG relates to short- and long-term cognitive functioning after cardiac arrest
Authors' conclusion
Early resting-state EEG parameters relate with short-term global cognitive functioning and with memory function at one year after cardiac arrest.
Study context
- Population
- Cardiac arrest survivors with EEG around one week after cardiac arrest
- Participants
- 80 survivors
- Primary endpoint
- Association of quantitative EEG measures (power spectral density, nATR, peak frequency, center of gravity (CoG)) with global cognitive functioning (MoCA)
- Follow-up
- One week, three and twelve months
Primary result
As reported in the abstract
MoCA at one week · one week
βnATR

Further findings
Montreal Cognitive Assessment (MoCA) at three months
- βnATR
- 2.49; P 0.01
MoCA at twelve months
- No EEG metrics significantly related to MoCA
Memory performance (neuropsychological examination) · twelve months
- Normalized alpha-to-theta ratio (nATR) and peak frequency related with memory performance
- Pearson correlation coefficients
- Consistent in sensitivity analyses
