ABSTRACT
Objective To determine whether sleep structures,the waveform components of NREM and rapid eye movement (REM) sleep, and the relationship between sleep variables and mental status are altered. Methods Totally 16 Alzheimer's disease(AD) patients and 16 age-matched controls were studied for two consecutive nights.All cases were video-monitored during the recordings of electroencephalography,electro-oculography,electrocardiography,electromyography in chin,and nasal airflow. Results (1) Compared with normal controls,duration of total sleep ( F =6.30, P =0.017 9),stage Ⅱ sleep ( F =16.03, P =0.000 4),and REM sleep ( F =9.84, P =0.002 1) were remarkably decreased,but waveform components of slow-wave (stage Ⅲ-IV) sleep ( F =11.50, P =0.004) were increased in AD patients.(2) Sleep spindle duration and density,and its relative and absolute power,and K complex density ( F =13.64~79.11, P
