Obstructive sleep apnea disrupts non-rapid eye movement sleep expression and impairs overnight memory retention in cognitively intact older adults at elevated risk for Alzheimer's disease.
Slow sigma power predicted memory retention with B=0.203 (p=0.007), whereas theta power clusters also demonstrated significant associations with word-pairs recall performance.
Overnight clinical polysomnography with 256-channel electroencephalography reveals that respiratory disturbances during sleep impair the neural oscillatory mechanisms necessary for memory.
