Abstract

Objective The purpose of this study was to investigate the features of polysomnography (PSG) parameters in patients with insomnia. Methods Polysomnographic recordings were performed in 62 patients with insomnia and 22 normal subjects. The sleep parameters were analyzed. Results A prolonged sleep latency (21.7 minutes longer than normal control), increased awake frequency (5.4 awakes more than normal), decreased total sleep duration (330.6 minutes shorter than normal), low sleep efficiency (73.3% lower than normal), abnormal sleep architecture such as decreased REM sleep (17.1%) and decreased REM density and REM activity were found in patients with insomnia. The difference between subjective sleep and objective estimates of sleep was significant ( P 0.05～0.01). Conclusion There are varying features of PSG parameters with patients insomnia. PSG may be helpful in evaluating the sleep quality of insomnia.
