Comparison of a single-channel EEG sleep study to polysomnography.

摘要: Summary An accurate home sleep study to assess electroencephalography (EEG)-based stages and EEG power would be advantageous for both clinical research purposes, such as longitudinal studies measuring changes in over time. The purpose of this was compare scoring a single-channel recorded simultaneously on the forehead against attended polysomnography. Participants were recruited from centre investigating cognitively normal ageing Alzheimer's disease. Analysis overall epoch-by-epoch agreement found strong substantial between compared polysomnography (κ = 0.67). Slow wave activity frontal regions also similar when comparing device As expected, Stage N1 showed poor (sensitivity 0.2) due lack occipital electrodes. Other parameters, latency rapid eye movement (REM) onset latency, had decreased agreement. with disrupted consolidation, obstructive apnea, We suspect that disagreement parameters is partially altered waveform morphology and/or poorer signal quality derivation. Our results show provides comparable assessing REM, combined Stages N2 N3 several other including slow activity. data establish can useful tool.
