Slow-frequency electroencephalography activity during wake and sleep in obesity hypoventilation syndrome

Study Objective Neurophysiological activity during wake and sleep states in obesity hypoventilation (OHS) and its relationship with neurocognitive function is not well understood. This study compared OHS with equally obese obstructive sleep apnea (OSA) patients, with similar apnea-hypopnea indices. Methods Resting wake and overnight sleep electroencephalography (EEG) recordings, neurocognitive tests, and sleepiness, depression and anxiety scores...
